We will have a period of using both C++ and Rust, and both cargo and CMake, leveraging FFI tools (see below). + +The work will **proceed on master**: no long-lived branches. Tests and CI continue to pass at every commit for recent Linux and Mac. Centos7, \*BSD, etc may be temporarily disabled if they prove problematic. + +The Rust code will initially resemble the replaced C++. Fidelity to existing code is more important than Rust idiomaticity, to aid review and bisecting. But don't take this to extremes - use judgement. + +The port will proceed "outside in." We'll start with leaf components (e.g. builtins) and proceed towards the core. Some components will have both a Rust and C++ implementation (e.g. FLOG), in other cases we'll change the existing C++ to invoke the new Rust implementations (builtins). + +After porting the C++, we'll replace CMake. + +We will continue to use wide chars, locales, gettext, printf format strings, and PCRE2. We will not change the fish scripting language at all. We will _not_ use this as an opportunity to fix existing design flaws, with a few carefully chosen exceptions. See [Strings](#strings). + +We will not use tokio, serde, async, or other fancy Rust frameworks initially. + +### FFI + +Rust/C++ interop will use [autocxx](https://github.com/google/autocxx), [Cxx](https://cxx.rs), and possibly [bindgen](https://rust-lang.github.io/rust-bindgen/). I've forked these for fish (see the Development Guide). Once the port is done, we will stop using them, except perhaps bindgen for PCRE2. + +We will use [corrosion](https://github.com/corrosion-rs/corrosion) for CMake integration. + +Inefficiencies (e.g. extra string copying) at the FFI layer are fine, since it will all get thrown away. + +Tests can stay in fish_tests.cpp or be moved into Rust .rs files; either is fine. + +### Strings + +Rust's `String` / `&str` types cannot represent non-UTF8 filenames or data using the default encoding scheme. That's why all string conversions must go through fish's encoding scheme (using the private-use area to encode invalid sequences). For example, fish cannot use `File::open` with a `&str` because the decoding will be incorrect. + +So instead of `String`, fish will use its own string type, and manage encoding and decoding as it does today. However we will make some specific changes: + +1. Drop the nul-terminated requirement. When passing `const wchar_t*` back to C++, we will allocate and copy into a nul-terminated buffer. +2. Drop support for 16-bit wchar. fish will use UTF32 on all platforms, and manage conversions itself. + +After the port we can consider moving to UTF-8, for memory usage reasons. + +See the Rust Development Guide for more on strings. + +### Thread Safety + +Allowing [background functions](https://github.com/fish-shell/fish-shell/issues/238) and concurrent functions has been a goal for many years. I have been nursing [a long-lived branch](https://github.com/ridiculousfish/fish-shell/tree/concurrent_even_simpler) which allows full threaded execution. But though the changes are small, I have been reluctant to propose them, because they will make reasoning about the shell internals too complex: it is difficult in C++ to check and enforce what crosses thread boundaries. + +This is Rust's bread and butter: we will encode thread requirements into our types, making it explicit and compiler-checked, via Send and Sync. Rust will allow turning on concurrent mode in a safe way, with a manageable increase in complexity, finally enabling this feature. + +## Timeline + +Handwaving, 6 months? Frankly unknown - there's 102 remaining .cpp files of various lengths. It'll go faster as we get better at it. Peter (ridiculous_fish) is motivated to work on this, other current contributors have some Rust as well, and we may also get new contributors from the Rust community. Part of the point is to make contribution easier. + +## Links + +- [Packaging Rust projects](https://wiki.archlinux.org/title/Rust_package_guidelines) from Arch Linux diff --git a/doc_internal/rust-devel.md b/doc_internal/rust-devel.md new file mode 100644 index 000000000..83edc9870 --- /dev/null +++ b/doc_internal/rust-devel.md @@ -0,0 +1,162 @@ +# fish-shell Rust Development Guide + +This describes how to get started building fish-shell in its partial Rust state, and how to contribute to the port. + +## Overview + +fish is in the process of transitioning from C++ to Rust. The fish project has a Rust crate embedded at path `fish-rust`. This crate builds a Rust library `libfish_rust.a` which is linked with the C++ `libfish.a`. Existing C++ code will be incrementally migrated to this crate; then CMake will be replaced with cargo and other Rust-native tooling. + +Important tools used during this transition: + +1. [Corrosion](https://github.com/corrosion-rs/corrosion) to invoke cargo from CMake. +2. [cxx](http://cxx.rs) for basic C++ <-> Rust interop. +3. [autocxx](https://google.github.io/autocxx/) for using C++ types in Rust. + +We use forks of the last two - see the FFI section below. No special action is required to obtain these packages. They're downloaded by cargo. + +## Building + +### Build Dependencies + +fish-shell currently depends on Rust 1.67 or later. To install Rust, follow https://rustup.rs. + +### Build via CMake + +It is recommended to build inside `fish-shell/build`. This will make it easier for Rust to find the `config.h` file. + +Build via CMake as normal (use any generator, here we use Ninja): + +```shell +$ cd fish-shell +$ mkdir build && cd build +$ cmake -G Ninja .. +$ ninja +``` + +This will create the usual fish executables. + +### Build just libfish_rust.a with Cargo + +The directory `fish-rust` contains the Rust sources. These require that CMake has been run to produce `config.h` which is necessary for autocxx to succeed. + +Follow the "Build from CMake" steps above, and then: + +```shell +$ cd fish-shell/fish-rust +$ cargo build +``` + +This will build only the library, not a full working fish, but it allows faster iteration for Rust development. That is, after running `cmake` you can open the `fish-rust` as the root of a Rust crate, and tools like rust-analyzer will work. + +## Development + +The basic development loop for this port: + +1. Pick a .cpp (or in some cases .h) file to port, say `util.cpp`. +2. Add the corresponding `util.rs` file to `fish-rust/`. +3. Reimplement it in Rust, along with its dependencies as needed. Match the existing C++ code where practical, including propagating any relevant comments. + - Do this even if it results in less idiomatic Rust, but avoid being super-dogmatic either way. + - One technique is to paste the C++ into the Rust code, commented out, and go line by line. +4. Decide whether any existing C++ callers should invoke the Rust implementation, or whether we should keep the C++ one. + - Utility functions may have both a Rust and C++ implementation. An example is `FLOG` where interop is too hard. + - Major components (e.g. builtin implementations) should _not_ be duplicated; instead the Rust should call C++ or vice-versa. + +You will likely run into limitations of [`autocxx`](https://google.github.io/autocxx/) and to a lesser extent [`cxx`](https://cxx.rs/). See the FFI sections below. + +## Type Mapping + +### Strings + +Fish will mostly _not_ use Rust's `String/&str` types as these cannot represent non-UTF8 data using the default encoding. + +fish's primary string types will come from the [`widestring` crate](https://docs.rs/widestring). The two main string types are `WString` and `&wstr`, which are renamed [Utf32String](https://docs.rs/widestring/latest/widestring/utfstring/struct.Utf32String.html) and [Utf32Str](https://docs.rs/widestring/latest/widestring/utfstr/struct.Utf32Str.html). `WString` is an owned, heap-allocated UTF32 string, `&wstr` a borrowed UTF32 slice. + +In general, follow this mapping when porting from C++: + +- `wcstring` -> `WString` +- `const wcstring &` -> `&wstr` +- `const wchar_t *` -> `&wstr` + +None of the Rust string types are nul-terminated. We're taking this opportunity to drop the nul-terminated aspect of wide string handling. + +#### Creating strings + +One may create a `&wstr` from a string literal using the `wchar::L!` macro: + +```rust +use crate::wchar::{wstr, L!} + +fn get_shell_name() -> &'static wstr { + L!("fish") +} +``` + +There is also a `widestrs` proc-macro which enables L as a _suffix_, to reduce the noise. This can be applied to any block, including modules and individual functions: + +```rust +use crate::wchar::{wstr, widestrs} + +[#widestrs] +fn get_shell_name() -> &'static wstr { + "fish"L // equivalent to L!("fish") +} +``` + +### Strings for FFI + +`WString` and `&wstr` are the common strings used by Rust components. At the FII boundary there are some additional strings for interop. _All of these are temporary for the duration of the port._ + +- `CxxWString` is the Rust binding of `std::wstring`. It is the wide-string analog to [`CxxString`](https://cxx.rs/binding/cxxstring.html) and is [added in our fork of cxx](https://github.com/ridiculousfish/cxx/blob/fish/src/cxx_wstring.rs). This is useful for functions which return e.g. `const wcstring &`. +- `W0String` is renamed [U32CString](https://docs.rs/widestring/latest/widestring/ucstring/struct.U32CString.html). This is basically `WString` except it _is_ nul-terminated. This is useful for getting a nul-terminated `const wchar_t *` to pass to C++ implementations. +- `wcharz_t` is an annoying C++ struct which merely wraps a `const wchar_t *`, used for passing these pointers from C++ to Rust. We would prefer to use `const wchar_t *` directly but `autocxx` refuses to generate bindings for types such as `std::vector<const wchar_t *>` so we wrap it in this silly struct. + +Note C++ `wchar_t`, Rust `char`, and `u32` are effectively interchangeable: you can cast pointers to them back and forth (except we check upon u32->char conversion). However be aware of which types are nul-terminated. + +These types should be confined to the FFI modules, in particular `wchar_ffi`. They should not "leak" into other modules. See the `wchar_ffi` module. + +### Format strings + +Rust's builtin `std::fmt` modules do not accept runtime-provided format strings, so we mostly won't use them, except perhaps for FLOG / other non-translated text. + +Instead we'll continue to use printf-style strings, with a Rust printf implementation. + +### Vectors + +See [`Vec`](https://cxx.rs/binding/vec.html) and [`CxxVector`](https://cxx.rs/binding/cxxvector.html). + +In many cases, `autocxx` refuses to allow vectors of certain types. For example, autocxx supports `std::vector` and `std::shared_ptr` but NOT `std::vector<std::shared_ptr<...>>`. To work around this one can create a helper (pointer, length) struct. Example: + +```cpp +struct RustFFIJobList { + std::shared_ptr<job_t> *jobs; + size_t count; +}; +``` + +This is just a POD (plain old data) so autocxx can generate bindings for it. Then it is trivial to convert it to a Rust slice: + +``` +pub fn get_jobs(ffi_jobs: &ffi::RustFFIJobList) -> &[SharedPtr<job_t>] { + unsafe { slice::from_raw_parts(ffi_jobs.jobs, ffi_jobs.count) } +} +``` + +## Development Tooling + +The [autocxx guidance](https://google.github.io/autocxx/workflow.html#how-can-i-see-what-bindings-autocxx-has-generated) is helpful: + +1. Install cargo expand (`cargo install cargo-expand`). Then you can use `cargo expand` to see the generated Rust bindings for C++. In particular this is useful for seeing failed expansions for C++ types that autocxx cannot handle. +2. In rust-analyzer, enable Proc Macro and Proc Macro Attributes. + +## FFI + +The boundary between Rust and C++ is referred to as the FII. + +`autocxx` and `cxx` both are designed for long-term interop: C++ and Rust coexisting for years. To this end, both emphasize safety: requiring lots of `unsafe`, `Pin`, etc. + +fish plans to use them only temporarily, with a focus on getting things working. To this end, both cxx and autocxx have been forked to support fish: + +1. Relax the requirement that all functions taking pointers are `unsafe` (this just added noise). +2. Add support for `wchar_t` as a recognized type, and `CxxWString` analogous to `CxxString`. + +See the `Cargo.toml` file for the locations of the forks. diff --git a/fish-rust/Cargo.lock

For now, it seems we can just use the nix crate with all features disabled as it still builds under Linux and FreeBSD in this state. --- fish-rust/Cargo.lock | 17 ----------------- fish-rust/Cargo.toml | 2 +- 2 files changed, 1 insertion(+), 18 deletions(-) diff --git a/fish-rust/Cargo.lock b/fish-rust/Cargo.lock index 850527213..8fa57912a 100644 --- a/fish-rust/Cargo.lock +++ b/fish-rust/Cargo.lock @@ -545,15 +545,6 @@ version = "2.5.0" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "2dffe52ecf27772e601905b7522cb4ef790d2cc203488bbd0e2fe85fcb74566d" -[[package]] -name = "memoffset" -version = "0.6.5" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "5aa361d4faea93603064a027415f07bd8e1d5c88c9fbf68bf56a285428fd79ce" -dependencies = [ - "autocfg", -] - [[package]] name = "miette" version = "5.5.0" @@ -619,8 +610,6 @@ dependencies = [ "bitflags", "cfg-if", "libc", - "memoffset", - "pin-utils", ] [[package]] @@ -669,12 +658,6 @@ version = "0.1.2" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "19b17cddbe7ec3f8bc800887bab5e717348c95ea2ca0b1bf0837fb964dc67099" -[[package]] -name = "pin-utils" -version = "0.1.0" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "8b870d8c151b6f2fb93e84a13146138f05d02ed11c7e7c54f8826aaaf7c9f184" - [[package]] name = "prettyplease" version = "0.1.23" diff --git a/fish-rust/Cargo.toml b/fish-rust/Cargo.toml index d21a02296..d671ff5da 100644 --- a/fish-rust/Cargo.toml +++ b/fish-rust/Cargo.toml @@ -13,7 +13,7 @@ errno = "0.2.8" inventory = { version = "0.3.3", optional = true} lazy_static = "1.4.0" libc = "0.2.137" -nix = "0.25.0" +nix = { version = "0.25.0", default-features = false, features = [] } num-traits = "0.2.15" unixstring = "0.2.7" widestring = "1.0.2" From 2dc2c8de3b180534c51d33df549f063933ea718e Mon Sep 17 00:00:00 2001 From: Mahmoud Al-Qudsi <mqudsi@neosmart.net> Date: Thu, 2 Feb 2023 15:19:26 -0600 Subject: [PATCH 020/831] Fix FreeBSD CI builds of rust-enabled codebase Use rustup to install the latest version of rust.

Some thoughts on the conventions: Types that live only inside Rust follow Rust naming convention ("FeatureMetadata"). Types that live on both sides of the language boundary follow the existing naming ("feature_flag_t"). The alternative is to define a type alias ("using feature_flag_t = rust::FeatureFlag") but that doesn't seem to be supported in "[cxx::bridge]" blocks. We could put it in a header ("future_feature_flags.h"). "feature_metadata_t" is a variant of "FeatureMetadata" that can cross the language boundary. This has the advantage that we can avoid tainting "FeatureMetadata" with "CxxString" and such. This is an experimental approach, probably not what we should do in general. --- CMakeLists.txt | 2 +- fish-rust/build.rs | 1 + fish-rust/src/ffi_init.rs | 1 + fish-rust/src/future_feature_flags.rs | 256 ++++++++++++++++++++++++++ fish-rust/src/lib.rs | 1 + src/builtins/status.cpp | 23 +-- src/builtins/string.cpp | 4 +- src/common.cpp | 6 +- src/fish.cpp | 6 +- src/fish_indent.cpp | 4 +- src/fish_tests.cpp | 49 ++--- src/future_feature_flags.cpp | 76 -------- src/future_feature_flags.h | 105 ----------- src/highlight.cpp | 4 +- src/parse_util.cpp | 4 +- src/tokenizer.cpp | 4 +- src/wildcard.cpp | 4 +- 17 files changed, 303 insertions(+), 247 deletions(-) create mode 100644 fish-rust/src/future_feature_flags.rs delete mode 100644 src/future_feature_flags.cpp delete mode 100644 src/future_feature_flags.h diff --git a/CMakeLists.txt b/CMakeLists.txt index 35c5d5605..22d4c6af0 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -118,7 +118,7 @@ set(FISH_SRCS src/ast.cpp src/abbrs.cpp src/autoload.cpp src/color.cpp src/common.cpp src/complete.cpp src/env.cpp src/env_dispatch.cpp src/env_universal_common.cpp src/event.cpp src/exec.cpp src/expand.cpp src/fallback.cpp src/fd_monitor.cpp src/fish_version.cpp - src/flog.cpp src/function.cpp src/future_feature_flags.cpp src/highlight.cpp + src/flog.cpp src/function.cpp src/highlight.cpp src/history.cpp src/history_file.cpp src/input.cpp src/input_common.cpp src/io.cpp src/iothread.cpp src/job_group.cpp src/kill.cpp src/null_terminated_array.cpp src/operation_context.cpp src/output.cpp diff --git a/fish-rust/build.rs b/fish-rust/build.rs index e3c7c7f10..56cb36e6d 100644 --- a/fish-rust/build.rs +++ b/fish-rust/build.rs @@ -22,6 +22,7 @@ fn main() -> miette::Result<()> { "src/fd_readable_set.rs", "src/ffi_init.rs", "src/ffi_tests.rs", + "src/future_feature_flags.rs", "src/smoke.rs", "src/topic_monitor.rs", "src/util.rs", diff --git a/fish-rust/src/ffi_init.rs b/fish-rust/src/ffi_init.rs index 018d722b4..95293e8e2 100644 --- a/fish-rust/src/ffi_init.rs +++ b/fish-rust/src/ffi_init.rs @@ -18,6 +18,7 @@ mod ffi2 { /// Entry point for Rust-specific initialization. fn rust_init() { crate::topic_monitor::topic_monitor_init(); + crate::future_feature_flags::future_feature_flags_init(); } /// FFI bridge for activate_flog_categories_by_pattern(). diff --git a/fish-rust/src/future_feature_flags.rs b/fish-rust/src/future_feature_flags.rs new file mode 100644 index 000000000..3755bbfa4 --- /dev/null +++ b/fish-rust/src/future_feature_flags.rs @@ -0,0 +1,256 @@ +//!

This helps when the terminal and fish disagree on the width of the prompt, because we are now definitely in the correct place, so we can only overwrite a bit of the prompt (if it renders longer than we expected) or leave space after the prompt. Both of these are benign in comparison to staircase effects we would otherwise get. Unfortunately, midnight commander ("mc") tries to extract the last line of the prompt, and does so in a way that is overly naive - it resets everything to 0 when it sees a `\r`, and doesn't account for cursor movement. In effect it's playing a terminal, but not committing to the bit. Since this has been an open request in mc for quite a while, we hack around it, by checking the $MC_SID environment variable. If we see it, we skip the clearing. We end up most likely doing relative movement from where we think we are, and in most cases it should be *fine*. --- src/env_dispatch.cpp | 8 ++++++++ src/screen.cpp | 12 +++++++++++- src/screen.h | 2 ++ 3 files changed, 21 insertions(+), 1 deletion(-) diff --git a/src/env_dispatch.cpp b/src/env_dispatch.cpp index 28282f13e..9c3882ce0 100644 --- a/src/env_dispatch.cpp +++ b/src/env_dispatch.cpp @@ -484,6 +484,14 @@ static void initialize_curses_using_fallbacks(const environment_t &vars) { // Apply any platform-specific hacks to cur_term/ static void apply_term_hacks(const environment_t &vars) { UNUSED(vars);

Default file expansion still suppresses leading dots, but now custom completions can create leading-dot completions and they will be offered.

At this moment, even oldstable Debian (buster) has meson 0.49.2 -- which means it is unlikely someone will be affected. --------- Co-authored-by: Mahmoud Al-Qudsi <mqudsi@neosmart.net> --- share/completions/meson.fish | 343 +++++++++++++++++++++++++++++++---- 1 file changed, 303 insertions(+), 40 deletions(-) diff --git a/share/completions/meson.fish b/share/completions/meson.fish index 9a3fe94de..cd9f02864 100644 --- a/share/completions/meson.fish +++ b/share/completions/meson.fish @@ -1,52 +1,315 @@ # Completions for the meson build system (http://mesonbuild.com/) -set -l basic_arguments \ - "h,help,show help message and exit" \ - ",stdsplit,Split stdout and stderr in test logs" \ - ",errorlogs,Print logs from failing test(s)" \ - ",werror,Treat warnings as errors" \ - ",strip,Strip targets on install" \ - "v,version,Show version number and exit" +function __fish_meson_needs_command + set -l cmd (commandline -opc) + set -e cmd[1] + argparse -s 'v/version' -- $cmd 2>/dev/null + or return 0 + not set -q argv[1] +end -set -l dir_arguments \ - ",localedir,Locale data directory [share/locale]" \ - ",sbindir,System executable directory [sbin]" \ - ",infodir,Info page directory [share/info]" \ - ",prefix,Installation prefix [/usr/local]" \ - ",mandir,Manual page directory [share/man]" \ - ",datadir,Data file directory [share]" \ - ",bindir,Executable directory [bin]" \ - ",sharedstatedir,Arch-agnostic data directory [com]" \ - ",libdir,Library directory [system default]" \ - ",localstatedir,Localstate data directory [var]" \ - ",libexecdir,Library executable directory [libexec]" \ - ",includedir,Header file directory [include]" \ - ",sysconfdir,Sysconf data directory [etc]" +function __fish_meson_using_command + set -l cmd (commandline -opc) + set -e cmd[1] + test (count $cmd) -eq 0 + and return 1 + contains -- $cmd[1] $argv + and return 0 +end -for arg in $basic_arguments - set -l parts (string split , -- $arg) - if not string match -q "" -- $parts[1] - complete -c meson -s "$parts[1]" -l "$parts[2]" -d "$parts[3]" +function __fish_meson_builddir + # Consider the value of -C option to detect the build directory + set -l cmd (commandline -opc) + argparse -i 'C=' -- $cmd + if set -q _flag_C + echo $_flag_C else - complete -c meson -l "$parts[2]" -d "$parts[3]" + echo . end end -for arg in $dir_arguments - set -l parts (string split , -- $arg) - complete -c meson -l "$parts[2]" -d "$parts[3]" -xa '(__fish_complete_directories)' +function __fish_meson_targets + set -l python (__fish_anypython); or return + meson introspect --targets (__fish_meson_builddir) | $python -S -c 'import json, sys +data = json.load(sys.stdin) +targets = set() +for target in data: + targets.add(target["name"]) +for name in targets: + print(name)' 2>/dev/null end -complete -c meson -s D -d "Set value of an option (-D foo=bar)" +function __fish_meson_subprojects + set -l python (__fish_anypython); or return + meson introspect --projectinfo (__fish_meson_builddir) | $python -S -c 'import json, sys +data = json.load(sys.stdin) +for subproject in data["subprojects"]: + print(subproject["name"])' 2>/dev/null +end -complete -c meson -l buildtype -xa 'plain debug debugoptimized release minsize' -d "Set build type [debug]" -complete -c meson -l layout -xa 'mirror flat' -d "Build directory layout [mirror]" -complete -c meson -l backend -xa 'ninja vs vs2010 vs2015 vs2017 xcode' -d "Compilation backend [ninja]" -complete -c meson -l default-library -xa 'shared static both' -d "Default library type [shared]" -complete -c meson -l warning-level -xa '1 2 3' -d "Warning level [1]" -complete -c meson -l unity -xa 'on off subprojects' -d "Unity build [off]" -complete -c meson -l cross-file -r -d "File describing cross-compilation environment" -complete -c meson -l wrap-mode -xa 'WrapMode.{default,nofallback,nodownload,forcefallback}' -d "Special wrap mode to use" +function __fish_meson_tests + # --list option shows suites in a short form, e.g. if a test "gvariant" + # is present both in "glib:glib" and "glib:slow" suites, it will be shown + # in a list as "glib:glib+slow / gvariant".

In practice, there's likely no need to worry -// about this too much, a survey <http://howardhinnant.github.io/clock_survey.html> of the different -// libraries indicates that `high_resolution_clock` is either an alias for `steady_clock` (in which -// case it offers no greater resolution) or it is an alias for `system_clock` (in which case, even -// when it offers a greater resolution than `steady_clock` it is not fit for use). - -static int64_t micros(struct timeval t) { - return (static_cast<int64_t>(t.tv_usec) + static_cast<int64_t>(t.tv_sec * 1E6)); -}; - -template <typename D1, typename D2> -static int64_t micros(const std::chrono::duration<D1, D2> &d) { - return std::chrono::duration_cast<std::chrono::microseconds>(d).count(); -}; - -timer_snapshot_t timer_snapshot_t::take() { - timer_snapshot_t snapshot; - - getrusage(RUSAGE_SELF, &snapshot.cpu_fish); - getrusage(RUSAGE_CHILDREN, &snapshot.cpu_children); - snapshot.wall = std::chrono::steady_clock::now(); - - return snapshot; -} - -wcstring timer_snapshot_t::print_delta(const timer_snapshot_t &t1, const timer_snapshot_t &t2, - bool verbose /* = true */) { - int64_t fish_sys_micros = micros(t2.cpu_fish.ru_stime) - micros(t1.cpu_fish.ru_stime); - int64_t fish_usr_micros = micros(t2.cpu_fish.ru_utime) - micros(t1.cpu_fish.ru_utime); - int64_t child_sys_micros = micros(t2.cpu_children.ru_stime) - micros(t1.cpu_children.ru_stime); - int64_t child_usr_micros = micros(t2.cpu_children.ru_utime) - micros(t1.cpu_children.ru_utime); - - // The result from getrusage is not necessarily realtime, it may be cached a few microseconds - // behind.

Helper ffi functions added to avoid needing to dynamically allocate an FdMonitorItem for every fd (we use dozens per basic prompt). I ported some functions from cpp to rust that are used only in the backend but without removing their existing cpp counterparts so cpp code can continue to use their version of them (`wperror` and `make_detached_pthread`). I ran into issues porting line-by-line logic because rust inverts the behavior of `std::remove_if(..)` by making it (basically) `Vec::retain_if(..)` so I replaced bools with an explict enum to make everything clearer. I'll port the cpp tests for this separately, for now they're using ffi. Porting closures was ugly. It's nothing hard, but it's very ugly as now each capturing lambda has been changed into an explicit struct that contains its parameters (that needs to be dynamically allocated), a standalone callback (member) function to replace the lambda contents, and a separate trampoline function to call it from rust over the shared C abi (not really relevant to x86_64 w/ its single calling convention but probably needed on other platforms). I don't like that `fd_monitor.rs` has its own `c_void`. I couldn't find a way to move that to `ffi.rs` but still get cxx bridge to consider it a shared POD. Every time I moved it to a different module, it would consider it to be an opaque rust type instead. I worry this means we're going to have multiple `c_void1`, `c_void2`, etc. types as we continue to port code to use function pointers. Also, rust treats raw pointers as foreign so you can't do `impl Send for * const Foo` even if `Foo` is from the same module. That necessitated a wrapper type (`void_ptr`) that implements `Send` and `Sync` so we can move stuff between threads. The code in fd_monitor_t has been split into two objects, one that is used by the caller and a separate one associated with the background thread (this is made nice and clean by rust's ownership model). Objects not needed under the lock (i.e. accessed by the background thread exclusively) were moved to the separate `BackgroundFdMonitor` type. --- CMakeLists.txt | 2 +- fish-rust/build.rs | 2 + fish-rust/src/builtins/mod.rs | 2 +- fish-rust/src/fd_monitor.rs | 567 +++++++++++++++++++++++++++++++ fish-rust/src/fd_readable_set.rs | 57 ++-- fish-rust/src/fds.rs | 68 +++- fish-rust/src/ffi.rs | 24 +- fish-rust/src/lib.rs | 2 + fish-rust/src/threads.rs | 67 ++++ fish-rust/src/wutil/mod.rs | 18 + src/fd_monitor.cpp | 215 ------------ src/fd_monitor.h | 140 -------- src/fds.cpp | 6 +- src/fds.h | 4 +- src/fish_tests.cpp | 64 ++-- src/io.cpp | 91 +++-- src/io.h | 6 + 17 files changed, 872 insertions(+), 463 deletions(-) create mode 100644 fish-rust/src/fd_monitor.rs create mode 100644 fish-rust/src/threads.rs delete mode 100644 src/fd_monitor.cpp delete mode 100644 src/fd_monitor.h diff --git a/CMakeLists.txt b/CMakeLists.txt index 27a9a5229..21e2074d6 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -117,7 +117,7 @@ set(FISH_BUILTIN_SRCS set(FISH_SRCS src/ast.cpp src/abbrs.cpp src/autoload.cpp src/color.cpp src/common.cpp src/complete.cpp src/env.cpp src/env_dispatch.cpp src/env_universal_common.cpp src/event.cpp - src/exec.cpp src/expand.cpp src/fallback.cpp src/fd_monitor.cpp src/fish_version.cpp + src/exec.cpp src/expand.cpp src/fallback.cpp src/fish_version.cpp src/flog.cpp src/function.cpp src/highlight.cpp src/history.cpp src/history_file.cpp src/input.cpp src/input_common.cpp src/io.cpp src/iothread.cpp src/job_group.cpp src/kill.cpp diff --git a/fish-rust/build.rs b/fish-rust/build.rs index cef14f542..907b3e0cc 100644 --- a/fish-rust/build.rs +++ b/fish-rust/build.rs @@ -19,7 +19,9 @@ fn main() -> miette::Result<()> { // This allows "Rust to be used from C++" // This must come before autocxx so that cxx can emit its cxx.h header. let source_files = vec![ + "src/fd_monitor.rs", "src/fd_readable_set.rs", + "src/fds.rs", "src/ffi_init.rs", "src/ffi_tests.rs", "src/future_feature_flags.rs", diff --git a/fish-rust/src/builtins/mod.rs b/fish-rust/src/builtins/mod.rs index dd530c8ae..16c4ca8cb 100644 --- a/fish-rust/src/builtins/mod.rs +++ b/fish-rust/src/builtins/mod.rs @@ -2,7 +2,7 @@ pub mod echo; pub mod emit; -mod exit; +pub mod exit; pub mod random; pub mod r#return; pub mod wait; diff --git a/fish-rust/src/fd_monitor.rs b/fish-rust/src/fd_monitor.rs new file mode 100644 index 000000000..9e74c64e5 --- /dev/null +++ b/fish-rust/src/fd_monitor.rs @@ -0,0 +1,567 @@ +use std::os::fd::{AsRawFd, RawFd}; +use std::sync::atomic::{AtomicU64, Ordering}; +use std::sync::{Arc, Mutex}; +use std::time::{Duration, Instant}; + +use self::fd_monitor::{c_void, new_fd_event_signaller, FdEventSignaller, ItemWakeReason}; +use crate::fd_readable_set::FdReadableSet; +use crate::fds::AutoCloseFd; +use crate::ffi::void_ptr; +use crate::flog::FLOG; +use crate::wutil::perror; +use cxx::SharedPtr; + +#[cxx::bridge] +mod fd_monitor { + /// Reason for waking an item + #[repr(u8)] + #[cxx_name = "item_wake_reason_t"] + enum ItemWakeReason { + /// The fd became readable (or was HUP'd) + Readable, + /// The requested timeout was hit + Timeout, + /// The item was "poked" (woken up explicitly) + Poke, + } + + // Defines and exports a type shared between C++ and rust + struct c_void { + _unused: u8, + } + + unsafe extern "C++" { + include!("fds.h"); + + /// An event signaller implemented using a file descriptor, so it can plug into + /// [`select()`](libc::select). + /// + /// This is like a binary semaphore.

Also rename the static global to stick to rust naming conventions. Note that `once_cell::sync::Lazy<T>` actually internally uses its own lock around the value, but in this case it's insufficient because `SmallRng` doesn't implement `SeedableRng` so we can't reseed it with only an `&mut` reference and must instead replace its value. We probably *could* still use `Lazy<SmallRng>` directly and then rely on `std::mem::swap()` to replace the contents of the shared global static without reassigning the variable directly with a new `SmallRng` instance, but I'm not sure that's a great idea. This is just a built-in, there's no real harm in locking twice (especially while fish remains essentially single-threaded). --- fish-rust/src/builtins/random.rs | 34 ++++++++++++++++++++------------ 1 file changed, 21 insertions(+), 13 deletions(-) diff --git a/fish-rust/src/builtins/random.rs b/fish-rust/src/builtins/random.rs index 22314774f..bcded00c5 100644 --- a/fish-rust/src/builtins/random.rs +++ b/fish-rust/src/builtins/random.rs @@ -5,7 +5,7 @@ STATUS_CMD_OK, STATUS_INVALID_ARGS, }; use crate::ffi::parser_t; -use crate::wchar::{widestrs, wstr}; +use crate::wchar::{wstr, L}; use crate::wgetopt::{wgetopter_t, wopt, woption, woption_argument_t}; use crate::wutil::{self, fish_wcstoi_radix_all, format::printf::sprintf, wgettext_fmt}; use num_traits::PrimInt; @@ -14,9 +14,8 @@ use rand::{Rng, SeedableRng}; use std::sync::Mutex; -static seeded_engine: Lazy<Mutex<SmallRng>> = Lazy::new(|| Mutex::new(SmallRng::from_entropy())); +static RNG: Lazy<Mutex<SmallRng>> = Lazy::new(|| Mutex::new(SmallRng::from_entropy())); -#[widestrs] pub fn random( parser: &mut parser_t, streams: &mut io_streams_t, @@ -26,8 +25,8 @@ pub fn random( let argc = argv.len(); let print_hints = false; - const shortopts: &wstr = "+:h"L; - const longopts: &[woption] = &[wopt("help"L, woption_argument_t::no_argument, 'h')]; + const shortopts: &wstr = L!("+:h"); + const longopts: &[woption] = &[wopt(L!("help"), woption_argument_t::no_argument, 'h')]; let mut w = wgetopter_t::new(shortopts, longopts, argv); while let Some(c) = w.wgetopt_long() { @@ -50,7 +49,6 @@ pub fn random( } } - let mut engine = seeded_engine.lock().unwrap(); let mut start = 0; let mut end = 32767; let mut step = 1; @@ -64,8 +62,10 @@ pub fn random( return STATUS_INVALID_ARGS; } - let rand = engine.gen_range(0..arg_count - 1); - streams.out.append(sprintf!("%ls\n"L, argv[i + 1 + rand])); + let rand = RNG.lock().unwrap().gen_range(0..arg_count - 1); + streams + .out + .append(sprintf!(L!("%ls\n"), argv[i + 1 + rand])); return STATUS_CMD_OK; } fn parse<T: PrimInt>( @@ -91,7 +91,10 @@ fn parse<T: PrimInt>( let num = parse::<i64>(streams, cmd, argv[i]); match num { Err(_) => return STATUS_INVALID_ARGS, - Ok(x) => *engine = SmallRng::seed_from_u64(x as u64), + Ok(x) => { + let mut engine = RNG.lock().unwrap(); + *engine = SmallRng::seed_from_u64(x as u64); + } } return STATUS_CMD_OK; } @@ -156,12 +159,17 @@ fn parse<T: PrimInt>( return STATUS_INVALID_ARGS; } - let rand = engine.gen_range(0..=possibilities); + let rand = { + let mut engine = RNG.lock().unwrap(); + engine.gen_range(0..=possibilities) + }; // Safe because end was a valid i64 and the result here is in the range start..=end. - let result: i64 = start.checked_add_unsigned(rand * step) - .and_then(|x| x.try_into().ok()).unwrap(); + let result: i64 = start + .checked_add_unsigned(rand * step) + .and_then(|x| x.try_into().ok()) + .unwrap(); - streams.out.append(sprintf!("%d\n"L, result)); + streams.out.append(sprintf!(L!("%d\n"), result)); return STATUS_CMD_OK; } From 77a474ee378bf5d297e7494c990cecb15ef2400d Mon Sep 17 00:00:00 2001 From: Xiretza <xiretza@xiretza.xyz> Date: Sat, 11 Feb 2023 18:15:27 +0100 Subject: [PATCH 121/831] Move POD components of library_data_t to separate struct This allows them to be accessed as regular fields from Rust, rather than having to create setter/getter methods for each of them. --- fish-rust/src/builtins/exit.rs | 4 ++-- fish-rust/src/builtins/return.rs | 9 +++++---- fish-rust/src/ffi.rs | 7 +++++++ src/parser.cpp | 10 ++-------- src/parser.h | 11 ++++++----- 5 files changed, 22 insertions(+), 19 deletions(-) diff --git a/fish-rust/src/builtins/exit.rs b/fish-rust/src/builtins/exit.rs index b0ffc0f77..8d8eed43b 100644 --- a/fish-rust/src/builtins/exit.rs +++ b/fish-rust/src/builtins/exit.rs @@ -2,7 +2,7 @@ use super::r#return::parse_return_value; use super::shared::io_streams_t; -use crate::ffi::{parser_t, Repin}; +use crate::ffi::parser_t; use crate::wchar::wstr; /// Function for handling the exit builtin. @@ -20,7 +20,7 @@ pub fn exit( // TODO: in concurrent mode this won't successfully exit a pipeline, as there are other parsers // involved.

Using pointers to get/set `termios` values with an assert to make sure we're using identical definitions on both sides (in cpp from the system headers and in rust from the libc crate as exported). I don't know why cxx bridge doesn't allow `SharedPtr<OpaqueRustType>` but we can work around it in C++ by converting a `Box<T>` to a `shared_ptr<T>` then convert it back when it needs to be destructed. I can't find a clean way of doing it from the cxx bridge wrapper so for now it needs to be done manually in the C++ code. Types/values that are drop-in ready over ffi are renamed to match the old cpp names but for types that now differ due to ffi difficulties I've left the `_ffi` in the function names to indicate that this isn't the "correct" way of using the types/methods. --- CMakeLists.txt | 2 +- fish-rust/build.rs | 1 + fish-rust/src/common.rs | 8 + fish-rust/src/job_group.rs | 352 +++++++++++++++++++++++++++++++++++++ fish-rust/src/lib.rs | 1 + fish-rust/src/signal.rs | 3 +- src/builtins/bg.cpp | 2 +- src/builtins/fg.cpp | 7 +- src/exec.cpp | 8 +- src/ffi.h | 15 ++ src/io.h | 2 +- src/job_group.cpp | 69 -------- src/job_group.h | 111 ------------ src/operation_context.h | 2 +- src/parse_execution.cpp | 9 +- src/parser.cpp | 2 +- src/parser.h | 2 +- src/postfork.cpp | 6 +- src/proc.cpp | 22 ++- src/proc.h | 2 +- 20 files changed, 416 insertions(+), 210 deletions(-) create mode 100644 fish-rust/src/job_group.rs create mode 100644 src/ffi.h delete mode 100644 src/job_group.cpp delete mode 100644 src/job_group.h diff --git a/CMakeLists.txt b/CMakeLists.txt index 39a770d2b..be0ea5193 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -120,7 +120,7 @@ set(FISH_SRCS src/exec.cpp src/expand.cpp src/fallback.cpp src/fish_version.cpp src/flog.cpp src/function.cpp src/highlight.cpp src/history.cpp src/history_file.cpp src/input.cpp src/input_common.cpp - src/io.cpp src/iothread.cpp src/job_group.cpp src/kill.cpp + src/io.cpp src/iothread.cpp src/kill.cpp src/null_terminated_array.cpp src/operation_context.cpp src/output.cpp src/pager.cpp src/parse_execution.cpp src/parse_tree.cpp src/parse_util.cpp src/parser.cpp src/parser_keywords.cpp src/path.cpp src/postfork.cpp diff --git a/fish-rust/build.rs b/fish-rust/build.rs index 95795f251..4b60b664b 100644 --- a/fish-rust/build.rs +++ b/fish-rust/build.rs @@ -26,6 +26,7 @@ fn main() -> miette::Result<()> { "src/ffi_init.rs", "src/ffi_tests.rs", "src/future_feature_flags.rs", + "src/job_group.rs", "src/parse_constants.rs", "src/redirection.rs", "src/smoke.rs", diff --git a/fish-rust/src/common.rs b/fish-rust/src/common.rs index 9655ddb5b..f2c59f40d 100644 --- a/fish-rust/src/common.rs +++ b/fish-rust/src/common.rs @@ -111,3 +111,11 @@ pub fn valid_func_name(name: &wstr) -> bool { }; true } + +pub const fn assert_send<T: Send>() -> () { + () +} + +pub const fn assert_sync<T: Sync>() -> () { + () +} diff --git a/fish-rust/src/job_group.rs b/fish-rust/src/job_group.rs new file mode 100644 index 000000000..0d377ce50 --- /dev/null +++ b/fish-rust/src/job_group.rs @@ -0,0 +1,352 @@ +use self::job_group::pgid_t; +use crate::common::{assert_send, assert_sync}; +use crate::wchar_ffi::{WCharFromFFI, WCharToFFI}; +use cxx::{CxxWString, UniquePtr}; +use std::num::{NonZeroI32, NonZeroU32}; +use std::sync::atomic::{AtomicBool, AtomicI32, Ordering}; +use std::sync::Mutex; +use widestring::WideUtfString; + +#[cxx::bridge] +mod job_group { + // Not only does cxx bridge not recognize libc::pid_t, it doesn't even recognize i32 as a POD + // type!

17 00:00:00 2001 From: Dmitry Gerasimov <di.gerasimov@gmail.com> Date: Sun, 12 Feb 2023 03:58:45 +0400 Subject: [PATCH 153/831] completions/meson: rewrite meson completions (#9539) Rewrite completions for meson to expose meson commands with their options and subcommands. New completions are based on the meson 1.0. Subcommands were introduced in meson 0.42.0 (August 2017), so new completions will only work for versions after 0.42.0. At this moment, even oldstable Debian (buster) has meson 0.49.2 -- which means it is unlikely someone will be affected. --------- Co-authored-by: Mahmoud Al-Qudsi <mqudsi@neosmart.net> (cherry picked from commit c3a72111e9860984aa9ebfaa440946f467357981) --- share/completions/meson.fish | 343 +++++++++++++++++++++++++++++++---- 1 file changed, 303 insertions(+), 40 deletions(-) diff --git a/share/completions/meson.fish b/share/completions/meson.fish index 9a3fe94de..cd9f02864 100644 --- a/share/completions/meson.fish +++ b/share/completions/meson.fish @@ -1,52 +1,315 @@ # Completions for the meson build system (http://mesonbuild.com/) -set -l basic_arguments \ - "h,help,show help message and exit" \ - ",stdsplit,Split stdout and stderr in test logs" \ - ",errorlogs,Print logs from failing test(s)" \ - ",werror,Treat warnings as errors" \ - ",strip,Strip targets on install" \ - "v,version,Show version number and exit" +function __fish_meson_needs_command + set -l cmd (commandline -opc) + set -e cmd[1] + argparse -s 'v/version' -- $cmd 2>/dev/null + or return 0 + not set -q argv[1] +end -set -l dir_arguments \ - ",localedir,Locale data directory [share/locale]" \ - ",sbindir,System executable directory [sbin]" \ - ",infodir,Info page directory [share/info]" \ - ",prefix,Installation prefix [/usr/local]" \ - ",mandir,Manual page directory [share/man]" \ - ",datadir,Data file directory [share]" \ - ",bindir,Executable directory [bin]" \ - ",sharedstatedir,Arch-agnostic data directory [com]" \ - ",libdir,Library directory [system default]" \ - ",localstatedir,Localstate data directory [var]" \ - ",libexecdir,Library executable directory [libexec]" \ - ",includedir,Header file directory [include]" \ - ",sysconfdir,Sysconf data directory [etc]" +function __fish_meson_using_command + set -l cmd (commandline -opc) + set -e cmd[1] + test (count $cmd) -eq 0 + and return 1 + contains -- $cmd[1] $argv + and return 0 +end -for arg in $basic_arguments - set -l parts (string split , -- $arg) - if not string match -q "" -- $parts[1] - complete -c meson -s "$parts[1]" -l "$parts[2]" -d "$parts[3]" +function __fish_meson_builddir + # Consider the value of -C option to detect the build directory + set -l cmd (commandline -opc) + argparse -i 'C=' -- $cmd + if set -q _flag_C + echo $_flag_C else - complete -c meson -l "$parts[2]" -d "$parts[3]" + echo . end end -for arg in $dir_arguments - set -l parts (string split , -- $arg) - complete -c meson -l "$parts[2]" -d "$parts[3]" -xa '(__fish_complete_directories)' +function __fish_meson_targets + set -l python (__fish_anypython); or return + meson introspect --targets (__fish_meson_builddir) | $python -S -c 'import json, sys +data = json.load(sys.stdin) +targets = set() +for target in data: + targets.add(target["name"]) +for name in targets: + print(name)' 2>/dev/null end -complete -c meson -s D -d "Set value of an option (-D foo=bar)" +function __fish_meson_subprojects + set -l python (__fish_anypython); or return + meson introspect --projectinfo (__fish_meson_builddir) | $python -S -c 'import json, sys +data = json.load(sys.stdin) +for subproject in data["subprojects"]: + print(subproject["name"])' 2>/dev/null +end -complete -c meson -l buildtype -xa 'plain debug debugoptimized release minsize' -d "Set build type [debug]" -complete -c meson -l layout -xa 'mirror flat' -d "Build directory layout [mirror]" -complete -c meson -l backend -xa 'ninja vs vs2010 vs2015 vs2017 xcode' -d "Compilation backend [ninja]" -complete -c meson -l default-library -xa 'shared static both' -d "Default library type [shared]" -complete -c meson -l warning-level -xa '1 2 3' -d "Warning level [1]" -complete -c meson -l unity -xa 'on off subprojects' -d "Unity build [off]" -complete -c meson -l cross-file -r -d "File describing cross-compilation environment" -complete -c meson -l wrap-mode -xa 'WrapMode.{default,nofallback,nodownload,forcefallback}' -d "Special wrap mode to use" +function __fish_meson_tests + # --list option shows suites in a short form, e.g. if a test "gvariant" + # is present both in "glib:glib" and "glib:slow" suites, it will be shown + # in a list as "glib:glib+slow / gvariant".

From a48c787439d093c7db3f030de7ba6f08fc2df8d0 Mon Sep 17 00:00:00 2001 From: Fabian Boehm <FHomborg@gmail.com> Date: Sat, 4 Feb 2023 18:57:41 +0100 Subject: [PATCH 154/831] Add workaround for Midnight Commander's issue with prompt extraction When we draw the prompt, we move the cursor to the actual position *we* think it is by issuing a carriage return (via `move(0,0)`), and then going forward until we hit the spot. This helps when the terminal and fish disagree on the width of the prompt, because we are now definitely in the correct place, so we can only overwrite a bit of the prompt (if it renders longer than we expected) or leave space after the prompt. Both of these are benign in comparison to staircase effects we would otherwise get. Unfortunately, midnight commander ("mc") tries to extract the last line of the prompt, and does so in a way that is overly naive - it resets everything to 0 when it sees a `\r`, and doesn't account for cursor movement. In effect it's playing a terminal, but not committing to the bit. Since this has been an open request in mc for quite a while, we hack around it, by checking the $MC_SID environment variable. If we see it, we skip the clearing. We end up most likely doing relative movement from where we think we are, and in most cases it should be *fine*.

However if we used Display, we would fail to FLOG non-display types like ThreadIDs. There is apparently no way in Rust to write a function which formats a value preferentially using Display, falling back to Debug. Fix this by introducing two new traits, FloggableDisplay and FloggableDebug. FloggableDisplay is implemented for all Display types, and FloggableDebug can be "opted into" for any Debug type: impl FloggableDebug for MyType {} Both traits have a 'to_flog_str' function. FLOG brings them both into scope, and Rust figures out which 'to_flog_str' gets called. --- fish-rust/src/flog.rs | 28 +++++++++++++++++++++++++++- fish-rust/src/threads.rs | 4 +++- fish-rust/src/topic_monitor.rs | 4 +++- 3 files changed, 33 insertions(+), 3 deletions(-) diff --git a/fish-rust/src/flog.rs b/fish-rust/src/flog.rs index 54550f429..6f6a154c3 100644 --- a/fish-rust/src/flog.rs +++ b/fish-rust/src/flog.rs @@ -136,6 +136,28 @@ pub fn all_categories() -> Vec<&'static category_t> { ); } +/// FLOG formats values.

We're forced to use an `Arc` for `ItemMaker` (née `item_maker_t`) because there's no other way to make it clear that its lifetime will last longer than the FdMonitor's. But once we've created an `Arc<T>` we can't call `Arc::get_mut()` to get an `&mut T` once we've created even a single weak reference to the Arc (because that weak ref could be upgraded to a strong ref at any time). This means we need to finish configuring any non-atomic properties (such as `ItemMaker::always_exit`) before we initialize the callback (which needs an `Arc<ItemMaker>` to do its thing). Because rust doesn't like self-referential types and because of the fact that we now need to create both the `ItemMaker` and the `FdMonitorItem` separately before we set the callback (at which point it becomes impossible to get a mutable reference to the `ItemMaker`), `ItemMaker::item` is dropped from the struct and we instead have the "constructor" for `ItemMaker` take a reference to an `FdMonitor` instance and directly add itself to the monitor's set, meaning we don't need to move the item out of the `ItemMaker` in order to add it to the `FdMonitor` set later. --- fish-rust/src/lib.rs | 3 + fish-rust/src/tests/fd_monitor.rs | 188 ++++++++++++++++++++++++++++++ fish-rust/src/tests/mod.rs | 1 + src/fish_tests.cpp | 141 ---------------------- 4 files changed, 192 insertions(+), 141 deletions(-) create mode 100644 fish-rust/src/tests/fd_monitor.rs create mode 100644 fish-rust/src/tests/mod.rs diff --git a/fish-rust/src/lib.rs b/fish-rust/src/lib.rs index 25a1752fc..6dd4b8e17 100644 --- a/fish-rust/src/lib.rs +++ b/fish-rust/src/lib.rs @@ -41,3 +41,6 @@ mod builtins;

Well, `assert!(!foo)` is nowhere near as readable as `assert_eq!(foo, false)` because of the ! noise from the macro. Uninlined format args is a stupid lint that Rust actually walked back when they made it an official warning because you still have to use a mix of inlined and un-inlined format args (the latter of which won't complain) since only idents can be inlined. --- fish-rust/src/lib.rs | 3 +++ fish-rust/src/tests/fd_monitor.rs | 4 +++- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/fish-rust/src/lib.rs b/fish-rust/src/lib.rs index 6dd4b8e17..c4c97c97e 100644 --- a/fish-rust/src/lib.rs +++ b/fish-rust/src/lib.rs @@ -3,6 +3,9 @@ #![allow(non_upper_case_globals)] #![allow(clippy::needless_return)] #![allow(clippy::manual_is_ascii_check)] +#![allow(clippy::bool_assert_comparison)] +#![allow(clippy::uninlined_format_args)] +#![allow(clippy::derivable_impls)] #[macro_use] mod common; diff --git a/fish-rust/src/tests/fd_monitor.rs b/fish-rust/src/tests/fd_monitor.rs index ff0e34086..7f6a72c45 100644 --- a/fish-rust/src/tests/fd_monitor.rs +++ b/fish-rust/src/tests/fd_monitor.rs @@ -96,7 +96,9 @@ fn callback(&self, fd: &mut AutoCloseFd, reason: ItemWakeReason) { fn write42(&self) { let buf = [0u8; 42]; let mut writer = self.writer.lock().expect("Mutex poisoned!"); - writer.write_all(&buf).expect("Error writing 42 bytes to pipe!"); + writer + .write_all(&buf) + .expect("Error writing 42 bytes to pipe!"); } } From e6994ea3ac81499866f3fd6894de5f7ece611487 Mon Sep 17 00:00:00 2001 From: Johannes Altmanninger <aclopte@gmail.com> Date: Sun, 5 Mar 2023 10:30:28 +0100 Subject: [PATCH 210/831] Remove obsolete clippy suppression This type has been extracted to an alias, so it is okay now. --- fish-rust/src/fd_monitor.rs | 1 - 1 file changed, 1 deletion(-) diff --git a/fish-rust/src/fd_monitor.rs b/fish-rust/src/fd_monitor.rs index 032e26afa..30ff14f17 100644 --- a/fish-rust/src/fd_monitor.rs +++ b/fish-rust/src/fd_monitor.rs @@ -120,7 +120,6 @@ fn from(value: u64) -> Self { /// only `src/io.cpp`) is ported to rust enum FdMonitorCallback { None, - #[allow(clippy::type_complexity)] Native(NativeCallback), Ffi(FfiCallback /* fn ptr */, void_ptr /* param */), } From c6756e932496aed969e1f46de10e3ffbbd16b330 Mon Sep 17 00:00:00 2001 From: Johannes Altmanninger <aclopte@gmail.com> Date: Sun, 5 Mar 2023 09:24:44 +0100 Subject: [PATCH 211/831] Canonicalize some wide string imports wchar.rs should not import let alone reexport FFI strings.

It might be necessary to execute `cargo build` as `cargo build -Zbuild-std` to get full coverage. When we're linking against the hybrid C++ codebase, the sanitizer library is injected into the binary by also include `-fsanitize=address` in CXXFLAGS - we do *not* want to manually opt-into `-lasan`. We also need to manually specify the desired target triple as a CMake variable and then explicitly pass it to all `cargo` invocations if building with ASAN. Corrosion has been patched to make sure it follows these rules. The `cargo-test` target is failing to link under ASAN. For some reason it has autocxx/ffi dependencies even though only rust-native, ffi-free code should be tested (and one would think the situation wouldn't change depending on the presence of the sanitizer flag). It's been disabled under ASAN for now. --- .github/workflows/main.yml | 15 +++++++++++++-- cmake/Rust.cmake | 2 +- cmake/Tests.cmake | 31 +++++++++++++++++++++++-------- 3 files changed, 37 insertions(+), 11 deletions(-) diff --git a/.github/workflows/main.yml b/.github/workflows/main.yml index 921eadea2..d7336b982 100644 --- a/.github/workflows/main.yml +++ b/.github/workflows/main.yml @@ -73,13 +73,22 @@ jobs: ubuntu-asan: runs-on: ubuntu-latest + env: + # Rust has two different memory sanitizers of interest; they can't be used at the same time: + # * AddressSanitizer detects out-of-bound access, use-after-free, use-after-return, + # use-after-scope, double-free, invalid-free, and memory leaks. + # * MemorySanitizer detects uninitialized reads. + # + RUSTFLAGS: "-Zsanitizer=address" + # RUSTFLAGS: "-Zsanitizer=memory -Zsanitizer-memory-track-origins" steps: - uses: actions/checkout@v3 - name: SetupRust uses: ATiltedTree/setup-rust@v1 with: - rust-version: 1.67 + # All -Z options require running nightly + rust-version: nightly - name: Install deps run: | sudo apt install gettext libncurses5-dev libpcre2-dev python3-pip tmux @@ -91,7 +100,9 @@ jobs: CXXFLAGS: "-fno-omit-frame-pointer -fsanitize=undefined -fsanitize=address -DFISH_CI_SAN" run: | mkdir build && cd build - cmake .. + # Rust's ASAN requires the build system to explicitly pass a --target triple.

The rust rewrite saw `std::bitset` replaced with `[bool; 65]` which could result in a lot of memory copy bandwidth each time we checked for and received no signals. The original C++ code would iterate over all signal slots to see if any were set. The code now returns a single u64 and only checks slots that are known to have signals via an intelligent `Iterator` impl. --- fish-rust/src/bitset.rs | 323 ++++++++++++++++++++++++++++++++++++++++ fish-rust/src/event.rs | 17 ++- fish-rust/src/lib.rs | 1 + 3 files changed, 334 insertions(+), 7 deletions(-) create mode 100644 fish-rust/src/bitset.rs diff --git a/fish-rust/src/bitset.rs b/fish-rust/src/bitset.rs new file mode 100644 index 000000000..5c279f04f --- /dev/null +++ b/fish-rust/src/bitset.rs @@ -0,0 +1,323 @@ +use num_traits::{AsPrimitive, FromPrimitive, PrimInt}; +use std::ops::{BitAndAssign, BitOrAssign}; + +pub struct BitSet<T>(T); + +impl<T> BitSet<T> +where + T: PrimInt + BitAndAssign<T> + BitOrAssign<T> + FromPrimitive + AsU8 + AsI64 + AsU64, + i64: AsPrimitive<T>, +{ + /// Set's the `i`th bit to `1`. + pub fn set(&mut self, i: usize) { + self.0 |= T::one() << i; + } + + /// Clears the `i`th bit (i.e. sets it to `0`). + pub fn unset(&mut self, i: usize) { + self.0 &= !(T::one() << i); + } + + /// Sets or clears the `i`th bit depending on the value of `v`. + /// + /// Equivalent to the following: + /// + /// ```no_run + /// let bitset = BitSet::new(0u64); + /// let v = todo!(); + /// if v { bitset.set(i) } else { bitset.unset(i) } + /// ``` + /// + /// except it is executed branchlessly. + pub fn toggle(&mut self, i: usize, v: bool) { + let v = T::from_u8(v as u8).unwrap(); + let mask = T::one() << i; + let bit: T = (-v.as_i64()).as_(); + self.0 = (self.0 & !mask) | (bit & mask); + } + + /// Clears all the bits in the `BitSet`. + pub fn clear(&mut self) { + self.0 = T::zero(); + } + + /// Tests whether the `i`th bit is set. + pub fn test(&self, i: usize) -> bool { + ((self.0 >> i).as_u8() & 0x01) == 0x01 + } + + /// If `i` is within `BitSet::size()`, returns whether or not the `i`th bit is set.

We could use NonZeroU8 since all signal values comfortably fit, but using i32 lets us avoid a fallible attempt at narrowing values returned from the system as integers to the narrower u8 type. Known signals are explicitly defined as constants and can be matched against with equality or with pattern matching in a `match` block. Unknown signal values are passed-through without causing any issues. We're using per-OS targeting to enable certain libc SIGXXX values - we could change this to dynamically detecting what's available in build.rs but then it might not match what libc exposes, still giving us build failures. --- fish-rust/src/signal.rs | 299 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 299 insertions(+) diff --git a/fish-rust/src/signal.rs b/fish-rust/src/signal.rs index 89bb68ade..d6f0f6a1a 100644 --- a/fish-rust/src/signal.rs +++ b/fish-rust/src/signal.rs @@ -1,3 +1,6 @@ +use std::borrow::Cow; +use std::num::NonZeroI32; + use crate::ffi; use crate::topic_monitor::{generation_t, invalid_generations, topic_monitor_principal, topic_t}; use crate::wchar::wstr; @@ -43,6 +46,7 @@ pub fn wait(&self) { } } +#[deprecated(note = "Use [`Signal::parse()`] instead.")] /// Get the integer signal value representing the specified signal. pub fn wcs2sig(s: &wstr) -> Option<usize> { let sig = ffi::wcs2sig(c_str!(s)); @@ -50,6 +54,7 @@ pub fn wcs2sig(s: &wstr) -> Option<usize> { sig.0.try_into().ok() } +#[deprecated(note = "Use [`Signal::name()`] instead.")] /// Get string representation of a signal. pub fn sig2wcs(sig: i32) -> &'static wstr { let s = ffi::sig2wcs(ffi::c_int(sig)); @@ -58,6 +63,7 @@ pub fn sig2wcs(sig: i32) -> &'static wstr { wstr::from_ucstr(s).expect("signal name should be valid utf-32") } +#[deprecated(note = "Use [`Signal::desc()`] instead.")] /// Returns a description of the specified signal. pub fn signal_get_desc(sig: i32) -> &'static wstr { let s = ffi::signal_get_desc(ffi::c_int(sig)); @@ -65,3 +71,296 @@ pub fn signal_get_desc(sig: i32) -> &'static wstr { wstr::from_ucstr(s).expect("signal description should be valid utf-32") } + +#[derive(Clone, Copy, Eq, PartialEq, PartialOrd, Ord)] +/// A wrapper around the system signal code. +pub struct Signal(NonZeroI32); + +impl Signal { + pub const SIGHUP: Signal = Signal::new(libc::SIGHUP); + pub const SIGINT: Signal = Signal::new(libc::SIGINT); + pub const SIGQUIT: Signal = Signal::new(libc::SIGQUIT); + pub const SIGILL: Signal = Signal::new(libc::SIGILL); + pub const SIGTRAP: Signal = Signal::new(libc::SIGTRAP); + pub const SIGABRT: Signal = Signal::new(libc::SIGABRT); + /// Available on BSD and macOS only. + #[cfg(any(target_os = "freebsd", target_os = "macos"))] + pub const SIGEMT: Signal = Signal::new(libc::SIGEMT); + pub const SIGFPE: Signal = Signal::new(libc::SIGFPE); + pub const SIGKILL: Signal = Signal::new(libc::SIGKILL); + pub const SIGBUS: Signal = Signal::new(libc::SIGBUS); + pub const SIGSEGV: Signal = Signal::new(libc::SIGSEGV); + pub const SIGSYS: Signal = Signal::new(libc::SIGSYS); + pub const SIGPIPE: Signal = Signal::new(libc::SIGPIPE); + pub const SIGALRM: Signal = Signal::new(libc::SIGALRM); + pub const SIGTERM: Signal = Signal::new(libc::SIGTERM); + pub const SIGURG: Signal = Signal::new(libc::SIGURG); + pub const SIGSTOP: Signal = Signal::new(libc::SIGSTOP); + pub const SIGTSTP: Signal = Signal::new(libc::SIGTSTP); + pub const SIGCONT: Signal = Signal::new(libc::SIGCONT); + pub const SIGCHLD: Signal = Signal::new(libc::SIGCHLD); + pub const SIGTTIN: Signal = Signal::new(libc::SIGTTIN); + pub const SIGTTOU: Signal = Signal::new(libc::SIGTTOU); + pub const SIGIO: Signal = Signal::new(libc::SIGIO); + pub const SIGXCPU: Signal = Signal::new(libc::SIGXCPU); + pub const SIGXFSZ: Signal = Signal::new(libc::SIGXFSZ); + pub const SIGVTALRM: Signal = Signal::new(libc::SIGVTALRM); + pub const SIGPROF: Signal = Signal::new(libc::SIGPROF); + pub const SIGWINCH: Signal = Signal::new(libc::SIGWINCH); + /// Available on BSD and macOS only. + #[cfg(any(target_os = "freebsd", target_os = "macos"))] + pub const SIGINFO: Signal = Signal::new(libc::SIGINFO); + pub const SIGUSR1: Signal = Signal::new(libc::SIGUSR1); + pub const SIGUSR2: Signal = Signal::new(libc::SIGUSR2); + /// Available on BSD only. + #[cfg(any(target_os = "freebsd"))] + pub const SIGTHR: Signal = Signal::new(32); // Not exposed by libc crate + /// Available on BSD only. + #[cfg(any(target_os = "freebsd"))] + pub const SIGLIBRT: Signal = Signal::new(33); // Not exposed by libc crate + #[cfg(target_os = "linux")] + /// Available on Linux only. + pub const SIGSTKFLT: Signal = Signal::new(libc::SIGSTKFLT); + #[cfg(target_os = "linux")] + /// Available on Linux only. + pub const SIGPWR: Signal = Signal::new(libc::SIGPWR); + + // Signals aliased to other signals + /// Available on Linux only.

However this causes problems for printf, which expects strtoul behavior. Add "modulo base" behavior which wraps the negative value to positive.

The result is null-terminated and may also contain interior null-characters. std::string allows this. Rust's null-terminated string, CString, does not like interior null-characters. This means we will need to use Vec<u8> or OsString for the places where we use interior null-characters. On the other hand, we want to use CString for places that require a null-terminator, because other Rust types don't guarantee the null-terminator. Turns out there is basically no overlap between the two use cases, so make it two functions. Their equivalents in Rust will have the same name, so we'll only need to adjust the type when porting. --- fish-rust/src/ffi.rs | 1 + fish-rust/src/wutil/wrealpath.rs | 4 ++-- src/common.cpp | 9 +++++++++ src/common.h | 4 ++++ src/env.cpp | 6 +++--- src/env_dispatch.cpp | 16 ++++++++-------- src/env_universal_common.cpp | 8 ++++---- src/exec.cpp | 5 +++-- src/expand.cpp | 2 +- src/fds.cpp | 2 +- src/fish_indent.cpp | 4 ++-- src/fish_tests.cpp | 10 +++++----- src/history.cpp | 2 +- src/null_terminated_array.cpp | 2 +- src/path.cpp | 8 ++++---- src/wutil.cpp | 24 ++++++++++++------------ 16 files changed, 61 insertions(+), 46 deletions(-) diff --git a/fish-rust/src/ffi.rs b/fish-rust/src/ffi.rs index deebfe238..0c648de05 100644 --- a/fish-rust/src/ffi.rs +++ b/fish-rust/src/ffi.rs @@ -101,6 +101,7 @@ generate!("re::regex_result_ffi") generate!("re::try_compile_ffi") generate!("wcs2string") + generate!("wcs2zstring") generate!("str2wcstring") generate!("signal_handle") diff --git a/fish-rust/src/wutil/wrealpath.rs b/fish-rust/src/wutil/wrealpath.rs index 87e6872e5..f4d155d6e 100644 --- a/fish-rust/src/wutil/wrealpath.rs +++ b/fish-rust/src/wutil/wrealpath.rs @@ -7,7 +7,7 @@ use cxx::let_cxx_string; use crate::{ - ffi::{str2wcstring, wcs2string}, + ffi::{str2wcstring, wcs2zstring}, wchar::{wstr, WString}, wchar_ffi::{WCharFromFFI, WCharToFFI}, }; @@ -19,7 +19,7 @@ pub fn wrealpath(pathname: &wstr) -> Option<WString> { return None; } - let mut narrow_path: Vec<u8> = wcs2string(&pathname.to_ffi()).from_ffi(); + let mut narrow_path: Vec<u8> = wcs2zstring(&pathname.to_ffi()).from_ffi(); // Strip trailing slashes.

Functions like mbrtowc are not exposed by the libc crate, so declare them ourselves. Since we don't know the definition of C macros, add two big hacks to make this work: 1. Replace MB_LEN_MAX and mbstate_t with values (resp types) that should be large enough for any implementation. 2. Detect the definition of MB_CUR_MAX in the build script. This requires more changes for each new libc. We could also use this approach for 1. Additionally, this commit brings a small behavior change to read_unquoted_escape(): we cannot decode surrogate code points like \UDE01 into a Rust char, so use � (\UFFFD, replacement character) instead. Previously, we added such code points to a wcstring; looks like they were ignored when printed. --- fish-rust/Cargo.lock | 1 + fish-rust/Cargo.toml | 1 + fish-rust/build.rs | 3 + fish-rust/src/common.rs | 1573 +++++++++++++++++++++++++++++- fish-rust/src/compat.c | 3 + fish-rust/src/compat.rs | 8 + fish-rust/src/env.rs | 5 + fish-rust/src/expand.rs | 61 +- fish-rust/src/ffi.rs | 5 - fish-rust/src/flog.rs | 10 +- fish-rust/src/lib.rs | 2 + fish-rust/src/path.rs | 4 +- fish-rust/src/tokenizer.rs | 7 +- fish-rust/src/wchar.rs | 51 +- fish-rust/src/wcstringutil.rs | 62 +- fish-rust/src/wildcard.rs | 13 + fish-rust/src/wutil/encoding.rs | 19 + fish-rust/src/wutil/mod.rs | 20 + fish-rust/src/wutil/wrealpath.rs | 15 +- src/ast.cpp | 5 +- src/builtins/complete.cpp | 7 +- src/builtins/read.cpp | 9 +- src/builtins/string.cpp | 5 +- src/common.cpp | 408 +------- src/common.h | 14 +- src/complete.cpp | 22 +- src/env.cpp | 8 +- src/env_universal_common.cpp | 4 +- src/expand.cpp | 3 +- src/fish_tests.cpp | 33 +- src/parse_util.cpp | 5 +- src/wildcard.cpp | 4 +- tests/checks/basic.fish | 3 + 33 files changed, 1837 insertions(+), 556 deletions(-) create mode 100644 fish-rust/src/compat.c create mode 100644 fish-rust/src/compat.rs create mode 100644 fish-rust/src/wildcard.rs create mode 100644 fish-rust/src/wutil/encoding.rs diff --git a/fish-rust/Cargo.lock b/fish-rust/Cargo.lock index 059017816..cbde7ffb6 100644 --- a/fish-rust/Cargo.lock +++ b/fish-rust/Cargo.lock @@ -368,6 +368,7 @@ dependencies = [ "autocxx", "autocxx-build", "bitflags", + "cc", "cxx", "cxx-build", "cxx-gen", diff --git a/fish-rust/Cargo.toml b/fish-rust/Cargo.toml index 24f803e47..1511d1637 100644 --- a/fish-rust/Cargo.toml +++ b/fish-rust/Cargo.toml @@ -26,6 +26,7 @@ widestring = "1.0.2" [build-dependencies] autocxx-build = "0.23.1" +cc = { git = "https://github.com/mqudsi/cc-rs", branch = "fish" } cxx-build = { git = "https://github.com/fish-shell/cxx", branch = "fish" } cxx-gen = { git = "https://github.com/fish-shell/cxx", branch = "fish" } miette = { version = "5", features = ["fancy"] } diff --git a/fish-rust/build.rs b/fish-rust/build.rs index 5ffbbabd1..4d2edfee5 100644 --- a/fish-rust/build.rs +++ b/fish-rust/build.rs @@ -1,6 +1,8 @@ use miette::miette; fn main() -> miette::Result<()> { + cc::Build::new().file("src/compat.c").compile("libcompat.a"); + let rust_dir = std::env::var("CARGO_MANIFEST_DIR").expect("Env var CARGO_MANIFEST_DIR missing"); let target_dir = std::env::var("FISH_RUST_TARGET_DIR").unwrap_or(format!("{}/{}", rust_dir, "target/")); @@ -25,6 +27,7 @@ fn main() -> miette::Result<()> { let source_files = vec![ "src/abbrs.rs", "src/event.rs", + "src/common.rs", "src/fd_monitor.rs", "src/fd_readable_set.rs", "src/fds.rs", diff --git a/fish-rust/src/common.rs b/fish-rust/src/common.rs index 48a7cf622..75780987d 100644 --- a/fish-rust/src/common.rs +++ b/fish-rust/src/common.rs @@ -1,13 +1,81 @@ -use crate::ffi; -use crate::wchar::{wstr, WString}; +//!

The following unexpected behaviors are: * The foreground color is not being applied when defined by the `fish_color_selection` variable. * `set_color` options (e.g., `--bold`) would not be applied under the cursor when selection begins in the middle of the command line or when the cursor moves forward after visually selecting text backward. With this change, visual selection respects the foreground color and any `set_color` options are applied consistently regardless of where visual selection begins and the position of the cursor during selection. --- src/reader.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/reader.cpp b/src/reader.cpp index 6f910dedd..be0992c06 100644 --- a/src/reader.cpp +++ b/src/reader.cpp @@ -1214,7 +1214,7 @@ void reader_data_t::paint_layout(const wchar_t *reason) { // Apply any selection. if (data.selection.has_value()) { - highlight_spec_t selection_color = {highlight_role_t::normal, highlight_role_t::selection}; + highlight_spec_t selection_color = {highlight_role_t::selection, highlight_role_t::selection}; auto end = std::min(selection->stop, colors.size()); for (size_t i = data.selection->start; i < end; i++) { colors.at(i) = selection_color; From 0ad3e3a45dc6a1853c13d8bccf3772199f51fdd0 Mon Sep 17 00:00:00 2001 From: ridiculousfish <rf@fishshell.com> Date: Sat, 8 Apr 2023 20:23:13 -0700 Subject: [PATCH 351/831] Changelog fix for #9717 --- CHANGELOG.rst | 1 + 1 file changed, 1 insertion(+) diff --git a/CHANGELOG.rst b/CHANGELOG.rst index cadddd25f..1def71f19 100644 --- a/CHANGELOG.rst +++ b/CHANGELOG.rst @@ -20,6 +20,7 @@ Interactive improvements - The history pager now shows fuzzy (subsequence) matches in the absence of exact substring matches (:issue:`9476`). - Command-specific tab completions may now offer results whose first character is a period.

Additionally, the starting point can occur before any option. This enables the following completions: * `git switch -c <local-name> <any-branch>` * `git switch <any-branch> -c <local-name>` * `git switch -d <any-starting-point>` * `git switch <any-branch> -d` The trade-off is this does allow for `git switch <remote-branch>` to be completed with an error.

To be clear this is `command -s` and friends, if you do `command grep` that's handled as a keyword. One issue here is that we can't get "one path or not" because I don't know how to translate a maybe_t?

Rust has no overloading, and we cannot have generic methods in the Node trait (due to a Rust limitation, the error is like "cannot be made into an object") so we include the type name in method names. Give clients like "indent_visitor_t" a Rust companion ("IndentVisitor") that takes care of the AST traversal while the AST consumption remains in C++ for now. In future, "IndentVisitor" should absorb the entirety of "indent_visitor_t". This pattern requires that "fish_indent" be exposed includable header to the CXX bridge. Alternatively, we could define FFI wrappers for recursive AST traversal. Rust requires we separate the AST visitors for "mut" and "const" scenarios. Take this opportunity to concretize both visitors: The only client that requires mutable access is the populator. To match the structure of the C++ populator which makes heavy use of function overloading, we need to add a bunch of functions to the trait. Since there is no other mutable visit, this seems acceptable. The "const" visitors never use "will_visit_fields_of()" or "did_visit_fields_of()", so remove them (though this is debatable). Like in the C++ implementation, the AST nodes themselves are largely defined via macros. Union fields like "Statement" and "ArgumentOrRedirection" do currently not use macros but may in future. This commit also introduces a precedent for a type that is defined in one CXX bridge and used in another one - "ParseErrorList". To make this work we need to manually define "ExternType". There is one annoyance with CXX: functions that take explicit lifetime parameters require to be marked as unsafe. This makes little sense because functions that return `&Foo` with implicit lifetime can be misused the same way on the C++ side. One notable change is that we cannot directly port "find_block_open_keyword()" (which is used to compute an error) because it relies on the stack of visited nodes. We cannot modify a stack of node references while we do the "mut" walk. Happily, an idiomatic solution is easy: we can tell the AST visitor to backtrack to the parent node and create the error there. Since "node_t::accept_base" is no longer a template we don't need the "node_visitation_t" trampoline anymore. The added copying at the FFI boundary makes things slower (memcpy dominates the profile) but it's not unusable, which is good news: $ hyperfine ./fish.{old,new}" -c 'source ../share/completions/git.fish'" Benchmark 1: ./fish.old -c 'source ../share/completions/git.fish' Time (mean ± σ): 195.5 ms ± 2.9 ms [User: 190.1 ms, System: 4.4 ms] Range (min … max): 193.2 ms … 205.1 ms 15 runs Benchmark 2: ./fish.new -c 'source ../share/completions/git.fish' Time (mean ± σ): 677.5 ms ± 62.0 ms [User: 665.4 ms, System: 10.0 ms] Range (min … max): 611.7 ms … 805.5 ms 10 runs Summary './fish.old -c 'source ../share/completions/git.fish'' ran 3.47 ± 0.32 times faster than './fish.new -c 'source ../share/completions/git.fish'' Leftovers: - Enum variants are still snakecase; I didn't get around to changing this yet. - "ast_type_to_string()" still returns a snakecase name.

In C++ we handle this by branching on maybe_t<env_var_t>::missing_or_empty(). If it returns false, we go on to access maybe_t<env_var_t>::value() aka operator*. In Rust, Environment::get() will return an Option<EnvVar>. We could define a MissingOrEmpty trait and implement it for Option<EnvVar>. However that will still leave us with ugly calls to Option::unwrap() (by convention Rust does use shorthands like *).

No need for common.rs to be as long as our old common.cpp! I left #[deprecated] stubs in common.rs to help redirect anyone porting code over that we can remove after the port has finished. Additionally, the fork guards had previously been left as a todo!() item but I ported that over. They're all called from the now-central threads::init() function so there isn't a need to call each individual thread-management-fn manually. The decision was made a while back to try and embrace/use the native rust thread functionality and utilities so the manual thread management code has been ripped out and was replaced with code that marshals the native rust values instead. The values won't line up with what the C++ code sees, but it never lined up anyway since each was using a separate counter to keep track of the values. --- fish-rust/src/common.rs | 64 +++++++++++++--------------------------- fish-rust/src/threads.rs | 30 +++++++++++++++++-- 2 files changed, 48 insertions(+), 46 deletions(-) diff --git a/fish-rust/src/common.rs b/fish-rust/src/common.rs index f7a153ca0..7fe8bb15a 100644 --- a/fish-rust/src/common.rs +++ b/fish-rust/src/common.rs @@ -22,7 +22,6 @@ use libc::{EINTR, EIO, O_WRONLY, SIGTTOU, SIG_IGN, STDERR_FILENO, STDIN_FILENO, STDOUT_FILENO}; use num_traits::ToPrimitive; use once_cell::sync::Lazy; -use std::cell::RefCell; use std::env; use std::ffi::{CString, OsString}; use std::mem::{self, ManuallyDrop}; @@ -32,7 +31,7 @@ use std::path::PathBuf; use std::rc::Rc; use std::str::FromStr; -use std::sync::atomic::{AtomicI32, AtomicU32, AtomicU64, Ordering}; +use std::sync::atomic::{AtomicI32, AtomicU32, Ordering}; use std::sync::Mutex; use std::time; use widestring_suffix::widestrs; @@ -1201,34 +1200,14 @@ pub fn should_suppress_stderr_for_tests() -> bool { unsafe { !PROGRAM_NAME.is_empty() && *PROGRAM_NAME != TESTS_PROGRAM_NAME } } -fn assert_is_main_thread() { - assert!(is_main_thread() || THREAD_ASSERTS_CFG_FOR_TESTING.load()); +#[deprecated(note = "Use threads::assert_is_main_thread() instead")] +pub fn assert_is_main_thread() { + crate::threads::assert_is_main_thread() } -fn assert_is_background_thread() { - assert!(!is_main_thread() || THREAD_ASSERTS_CFG_FOR_TESTING.load()); -} - -static THREAD_ASSERTS_CFG_FOR_TESTING: RelaxedAtomicBool = RelaxedAtomicBool::new(false); - -thread_local! { - static TL_TID: RefCell<u64> = RefCell::new(0); -} - -static S_LAST_THREAD_ID: AtomicU64 = AtomicU64::new(0); -fn next_thread_id() -> u64 { - // Note 0 is an invalid thread id. - // Note fetch_add is a CAS which returns the value *before* the modification. - 1 + S_LAST_THREAD_ID.fetch_add(1, Ordering::Relaxed) -} - -fn thread_id() -> u64 { - TL_TID.with(|tid| { - if *tid.borrow() == 0 { - *tid.borrow_mut() = next_thread_id() - } - *tid.borrow() - }) +#[deprecated(note = "Use threads::assert_is_background_thread() instead")] +pub fn assert_is_background_thread() { + crate::threads::assert_is_background_thread() } /// Format the specified size (in bytes, kilobytes, etc.) into the specified stringbuffer. @@ -1584,32 +1563,29 @@ pub fn timef() -> Timepoint { } } +#[deprecated(note = "Use threads::is_main_thread() instead")] +pub fn is_main_thread() -> bool { + crate::threads::is_main_thread() +} + /// Call the following function early in main to set the main thread.

The logic was incorrectly reversed before (it's easier to reason about when you realize that fish doesn't even compile under Windows because it uses tons of libc functions). As the code was actually never compiled, it wasn't actually tested for validity either and there were some issues that prevented it from compiling that have since been fixed. The logic has also been adjusted a bit to make it possible to use the rust-native int parsing instead of `libc::strtod()`. The code has been changed to use `once_cell::race::OnceBool` instead of `once_cell::sync::Lazy<T>` which imposes a greater runtime burden with locking and other overhead. We don't care if the code runs more than once on init (if calls were to race, though they probably don't) - just that the code isn't subsequently executed on each call. The `once_cell::race` module is a better fit here, though it doesn't expose the ergonomic `Lazy<T>` façade around its types. --- fish-rust/src/common.rs | 103 ++++++++++++++++++++++------------------ 1 file changed, 58 insertions(+), 45 deletions(-) diff --git a/fish-rust/src/common.rs b/fish-rust/src/common.rs index 7fe8bb15a..7afcd4c9a 100644 --- a/fish-rust/src/common.rs +++ b/fish-rust/src/common.rs @@ -1615,6 +1615,13 @@ pub fn restore_term_foreground_process_group_for_exit() { } } +fn slice_contains_slice<T: Eq>(a: &[T], b: &[T]) -> bool { + a.windows(b.len()).any(|aw| aw == b) +} + +#[cfg(target_os = "linux")] +static IS_WINDOWS_SUBSYSTEM_FOR_LINUX: once_cell::race::OnceBool = once_cell::race::OnceBool::new(); + /// Determines if we are running under Microsoft's Windows Subsystem for Linux to work around /// some known limitations and/or bugs. /// See https://github.com/Microsoft/WSL/issues/423 and Microsoft/WSL#2997 @@ -1623,55 +1630,61 @@ pub fn is_windows_subsystem_for_linux() -> bool { // overhead since there's no actual race condition here - even if multiple threads call this // routine simultaneously the first time around, we just end up needlessly querying uname(2) one // more time. - *IS_WINDOWS_SUBSYSTEM_FOR_LINUX -} - -fn slice_contains_slice<T: Eq>(a: &[T], b: &[T]) -> bool { - a.windows(b.len()).any(|aw| aw == b) -} - -#[cfg(not(windows))] -static IS_WINDOWS_SUBSYSTEM_FOR_LINUX: Lazy<bool> = Lazy::new(|| false); -#[cfg(windows)] -static IS_WINDOWS_SUBSYSTEM_FOR_LINUX: Lazy<bool> = Lazy::new(|| { - let mut info: libc::utsname = unsafe { mem::zeroed() }; - unsafe { - libc::uname(&mut info); - } - - // Sample utsname.release under WSL, testing for something like `4.4.0-17763-Microsoft` - if !slice_contains_slice(&info.release, b"Microsoft") { - return false; - } - let dash = info.release.iter().position('-'); - - if dash - .map(|d| unsafe { libc::strtod(&info.release[d + 1], std::ptr::null()) } >= 17763) - .unwrap_or(false) + #[cfg(not(target_os = "linux"))] { - return false; + false } - // #5298, #5661: There are acknowledged, published, and (later) fixed issues with - // job control under early WSL releases that prevent fish from running correctly, - // with unexpected failures when piping.

(In C++, we would either be using a plain C string which is always nul-terminated or we would be using (w)string::cstr() which similarly grants access to its nul-terminated buffer.) Aside from that, there's no need to explicitly check `if c2 == '\0'` because '\0' is not a valid hex digit so the `?` tacked on to `convert_hex_digit(c2)?` will abort and return `None` anyway. convert_hex_digit() is not appreciably faster than char::to_digit(16) and makes the code less maintainable since it encodes certain assumptions; since it's also not used consistently just drop it in favor of the std fn. Since the output string (per the decode logic) is always shorter than or equal to the input string, just reserve the input string size upfront to prevent vec reallocations. --- fish-rust/src/common.rs | 45 +++++++++++++++++------------------------ 1 file changed, 18 insertions(+), 27 deletions(-) diff --git a/fish-rust/src/common.rs b/fish-rust/src/common.rs index 62743cd1b..3db0f12d1 100644 --- a/fish-rust/src/common.rs +++ b/fish-rust/src/common.rs @@ -687,10 +687,14 @@ enum Mode { Some(result) } -/// Reverse the effects of `escape_string_url()`.

Also, improve over the C++ code by not relying on the build-time WSL status to determine if we are running on WSL at runtime since it's often the case that the fish binaries are built on a non-WSL host (for packaging) then executed on a WSL only at runtime. (But it's ok to assume if fish has been built for Windows or not Linux that it will either be run or not run on top of a Win32 character device system.) Also, port of the comment and relevant WSL and fish issue links over from the CPP codebase for posterity. --- fish-rust/src/common.rs | 21 ++++++++++++++------- 1 file changed, 14 insertions(+), 7 deletions(-) diff --git a/fish-rust/src/common.rs b/fish-rust/src/common.rs index 6f6071e15..a582b9d62 100644 --- a/fish-rust/src/common.rs +++ b/fish-rust/src/common.rs @@ -995,12 +995,19 @@ pub fn get_obfuscation_read_char() -> char { /// Name of the current program.

Also add type-erased destructor registration to callback_t. This allows for freeing variables allocated by the callback for debounce_t's perform_with_callback() that don't end up having their completion called due to a timeout. --- CMakeLists.txt | 2 +- fish-rust/src/ffi.rs | 18 ++++++ fish-rust/src/threads.rs | 96 +++++++++++++--------------- src/callback.h | 49 +++++++++++++++ src/iothread.cpp | 17 ----- src/iothread.h | 133 ++++++++++++++------------------------- 6 files changed, 160 insertions(+), 155 deletions(-) create mode 100644 src/callback.h delete mode 100644 src/iothread.cpp diff --git a/CMakeLists.txt b/CMakeLists.txt index ee2befa2d..12cc20e4c 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -118,7 +118,7 @@ set(FISH_SRCS src/exec.cpp src/expand.cpp src/fallback.cpp src/fish_indent_common.cpp src/fish_version.cpp src/flog.cpp src/function.cpp src/highlight.cpp src/history.cpp src/history_file.cpp src/input.cpp src/input_common.cpp - src/io.cpp src/iothread.cpp src/kill.cpp + src/io.cpp src/kill.cpp src/null_terminated_array.cpp src/operation_context.cpp src/output.cpp src/pager.cpp src/parse_execution.cpp src/parse_util.cpp src/parser.cpp src/parser_keywords.cpp src/path.cpp src/postfork.cpp diff --git a/fish-rust/src/ffi.rs b/fish-rust/src/ffi.rs index 25f0b3583..afc65e682 100644 --- a/fish-rust/src/ffi.rs +++ b/fish-rust/src/ffi.rs @@ -338,3 +338,21 @@ fn from(value: *const autocxx::c_void) -> Self { Self(value as *const _) } } + +impl core::convert::From<void_ptr> for *const u8 { + fn from(value: void_ptr) -> Self { + value.0 as *const _ + } +} + +impl core::convert::From<void_ptr> for *const core::ffi::c_void { + fn from(value: void_ptr) -> Self { + value.0 as *const _ + } +} + +impl core::convert::From<void_ptr> for *const autocxx::c_void { + fn from(value: void_ptr) -> Self { + value.0 as *const _ + } +} diff --git a/fish-rust/src/threads.rs b/fish-rust/src/threads.rs index 7fa0fed43..be6f45f31 100644 --- a/fish-rust/src/threads.rs +++ b/fish-rust/src/threads.rs @@ -51,6 +51,15 @@ impl FloggableDebug for ThreadId {} #[cxx::bridge] mod ffi { + unsafe extern "C++" { + include!("callback.h");

These have semantics that are deliberately different from the libc functions, such as consuming trailing whitespace, and disallowing `-` in unsigned versions. fish has started to drift away from these semantics; some divergence from C++ has crept in. Rename the existing `fish_wcs*` functions in Rust to remove the fish prefix, to express that they attempt to mirror libc semantics; then introduce `fish_` wrappers which are ported from C++. Also fix some miscellaneous bugs which have crept in, such as missing range checks. --- fish-rust/src/builtins/bg.rs | 33 +++--- fish-rust/src/builtins/math.rs | 54 +++++----- fish-rust/src/builtins/printf.rs | 6 +- fish-rust/src/builtins/random.rs | 41 ++++--- fish-rust/src/env/environment_impl.rs | 11 +- fish-rust/src/termsize.rs | 14 ++- fish-rust/src/wutil/wcstoi.rs | 149 ++++++++++++++++++++++---- src/parser.cpp | 2 +- src/parser.h | 2 +- 9 files changed, 211 insertions(+), 101 deletions(-) diff --git a/fish-rust/src/builtins/bg.rs b/fish-rust/src/builtins/bg.rs index affdb02f3..6e1b1315a 100644 --- a/fish-rust/src/builtins/bg.rs +++ b/fish-rust/src/builtins/bg.rs @@ -93,24 +93,25 @@ pub fn bg(parser: &mut parser_t, streams: &mut io_streams_t, args: &mut [&wstr]) } // The user specified at least one job to be backgrounded. + let mut pids: Vec<libc::pid_t> = Vec::new();

Alternatively, fish also automatically executes a function called ``fish_user_key_bindings`` if it exists. - Key bindings may use "modes", which mimics Vi's modal input behavior. The default mode is "default". Every key binding applies to a single mode; you can specify which one with ``-M MODE``. If the key binding should change the mode, you can specify the new mode with ``-m NEW_MODE``. The mode can be viewed and changed via the ``$fish_bind_mode`` variable. If you want to change the mode from inside a fish function, use ``set fish_bind_mode MODE``. +To save custom key bindings, put the ``bind`` statements into :ref:`config.fish <configuration>`.

It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] + +**Preamble** + +The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software - to make sure the software is free for all its users. + +This license, the Lesser General Public License, applies to some specially designated software packages - typically libraries - of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. + +When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. + +To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. + +For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. + +We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. + +To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. + +Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. + +Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. + +When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. + +We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. + +For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. + +In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. + +Although the Lesser General Public License is Less protective of the users'freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. + +The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. + +**TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION** + +- This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) + + "Source code for a work" means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. + + Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. + +1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. + + You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. + +2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: + + 1. The modified work must itself be a software library. + + 2. You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. + + 3. You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. + + 4. If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. + + (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) + + These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. + + Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. + + In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. + +3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. + + Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of the Library into a program that is not a library. + +4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. + +5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. + +6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: + + 1. Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine- readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) + + 2. Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. + + 3. Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. + + 4. If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. + + 5. Verify that the user has already received a copy of these materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. + + It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. + +7. You may place library facilities that are a work based on the Library side- by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: + + 1. Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. + + 2. Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. + +8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. + +9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. + +10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients'exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. + +11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. + + If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. + + It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. + + This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. + +12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. + +13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. + +14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. + + **NO WARRANTY** + +15.

It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] - -**Preamble** - -The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software - to make sure the software is free for all its users. - -This license, the Lesser General Public License, applies to some specially designated software packages - typically libraries - of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. - -When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. - -To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. - -For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. - -We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. - -To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. - -Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. - -Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. - -When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. - -We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. - -For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. - -In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. - -Although the Lesser General Public License is Less protective of the users'freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. - -The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. - -**TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION** - -- This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) - - "Source code for a work" means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. - - Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. - -1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. - - You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. - -2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: - - 1. The modified work must itself be a software library. - - 2. You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. - - 3. You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. - - 4. If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. - - (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) - - These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. - - Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. - - In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. - -3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. - - Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of the Library into a program that is not a library. - -4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. - -5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. - -6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: - - 1. Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine- readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) - - 2. Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. - - 3. Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. - - 4. If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. - - 5. Verify that the user has already received a copy of these materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. - - It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. - -7. You may place library facilities that are a work based on the Library side- by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: - - 1. Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. - - 2. Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. - -8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. - -9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. - -10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients'exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. - -11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. - - If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. - - It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. - - This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. - -12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. - -13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. - - Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. - -14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. - - **NO WARRANTY** - -15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - -16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. - ----- - **License for UTF8** ``fish`` also contains small amounts of code under the ISC license, namely the UTF-8 conversion functions.

The curses C library does a lot of header file magic with macro voodoo to make it easier to perform certain tasks (such as access or override string capabilities) but this functionality isn't actually directly exposed by the library's ABI. The rust wrapper eschews all of that for a more straight-forward implementation, directly wrapping only the basic curses library calls that are required to perform the tasks we care about. This should let us avoid the subtle cross-platform differences between the various curses implementations that plagued the previous C++ implementation. All functionality in this module that requires an initialized curses TERMINAL pointer (`cur_term`, traditionally) has been subsumed by the `Term` instance, which once initialized with `curses::setup()` can be obtained at any time with `curses::Term()` (which returns an Option that evaluates to `None` if `cur_term` hasn't yet been initialized). --- fish-rust/src/curses.rs | 273 ++++++++++++++++++++++++++++++++++++++++ fish-rust/src/lib.rs | 1 + 2 files changed, 274 insertions(+) create mode 100644 fish-rust/src/curses.rs diff --git a/fish-rust/src/curses.rs b/fish-rust/src/curses.rs new file mode 100644 index 000000000..37de139bb --- /dev/null +++ b/fish-rust/src/curses.rs @@ -0,0 +1,273 @@ +//!

ScopeGuard no longer uses ManuallyDrop; the memory management is now trivial and no longer requires `unsafe`. 2. The functions `cancel` and `rollback` have been removed, as these were unused. They can be added back later if needed. 3. `scoped_push` has been simplified in both signature and implementation. 4. `Projection` is no longer required and has been removed.

In this case, the "or" needs to kick the "backward-delete-char" out of the input queue. After doing so, it continues reading, but interprets the input as single-char binding. This breaks when the next key emits a multi-char sequence, like the arrow keys. Fix this by reading a full sequence, which means we need to run "read_char()" instead of "read_ch()" (confusing, right?). I'm still working on writing a test. Somehow this only reproduces in the history pager where Shift+Delete followed by down arrow emits "[B" (since we swallowed the leading escape char).

(127 was the status for syntax errors when piping to fish, so we stay consistent with that) We allow multiple `-c` commands, and this will return the regular status if the last `-c` succeeded. This is fundamentally an extremely weird situation but this is the simple targeted fix - we did nothing, unsuccessfully, so we should fail. Things to consider in future: 1. Return something better than 127 - that's the status for "unknown command"! 2. Fail after a `-c` failed, potentially even checking all of them before executing the first?

But we already *know* that it does because this is the expansion for the "trailing slash" - by definition all wildcard components up to here have already been checked. And it's not checking for directoryness either because it does F_OK. This will remove one `access()` per result, which will cut the number of syscalls needed for a glob that ends in a "/" in half.

It changes two colors - the autosuggestion and the pager description (i.e. the completion descriptions in the pager). In a bunch of terminals I've tested these are pretty similar - for the most part brblack for the suggestions is a bit brighter than 555, and yellow for the descriptions is less blue than the original. We could also make the descriptions brblack, but that's for later. Technically we are a bit naughty in having a few foreground and background pairs that might not be visible, but there's nothing we can do if someone makes white invisible on brblack.

to Rust - Add test to verify piped string replace exit code Ensure fields parsing error messages are the same. Note: C++ relied upon the value of the parsed value even when `errno` was set, that is defined behaviour we should not rely on, and cannot easilt be replicated from Rust. Therefore the Rust version will change the following error behaviour from: ```shell > string split --fields=a "" abc string split: Invalid fields value 'a' > string split --fields=1a "" abc string split: 1a: invalid integer ``` To: ```shell > string split --fields=a "" abc string split: a: invalid integer > string split --fields=1a "" abc string split: 1a: invalid integer ``` --- CMakeLists.txt | 4 +- fish-rust/src/abbrs.rs | 1 - fish-rust/src/builtins/mod.rs | 1 + fish-rust/src/builtins/shared.rs | 16 + fish-rust/src/builtins/string.rs | 493 +++++ fish-rust/src/builtins/string/collect.rs | 66 + fish-rust/src/builtins/string/escape.rs | 65 + fish-rust/src/builtins/string/join.rs | 99 + fish-rust/src/builtins/string/length.rs | 74 + fish-rust/src/builtins/string/match.rs | 406 ++++ fish-rust/src/builtins/string/pad.rs | 114 + fish-rust/src/builtins/string/repeat.rs | 145 ++ fish-rust/src/builtins/string/replace.rs | 251 +++ fish-rust/src/builtins/string/shorten.rs | 249 +++ fish-rust/src/builtins/string/split.rs | 285 +++ fish-rust/src/builtins/string/sub.rs | 115 ++ fish-rust/src/builtins/string/transform.rs | 49 + fish-rust/src/builtins/string/trim.rs | 99 + fish-rust/src/builtins/string/unescape.rs | 57 + fish-rust/src/builtins/tests/mod.rs | 1 + fish-rust/src/builtins/tests/string_tests.rs | 303 +++ fish-rust/src/common.rs | 27 + fish-rust/src/ffi.rs | 3 + fish-rust/src/parse_util.rs | 17 +- fish-rust/src/wcstringutil.rs | 9 +- src/abbrs.h | 1 - src/builtin.cpp | 6 +- src/builtin.h | 1 + src/builtins/string.cpp | 1949 ------------------ src/builtins/string.h | 14 - src/fish_tests.cpp | 544 ----- src/io.cpp | 15 + src/io.h | 9 + src/re.cpp | 316 --- src/re.h | 166 -- src/screen.cpp | 5 + src/screen.h | 2 + tests/checks/abbr.fish | 5 + tests/checks/string.fish | 85 +- 39 files changed, 3061 insertions(+), 3006 deletions(-) create mode 100644 fish-rust/src/builtins/string.rs create mode 100644 fish-rust/src/builtins/string/collect.rs create mode 100644 fish-rust/src/builtins/string/escape.rs create mode 100644 fish-rust/src/builtins/string/join.rs create mode 100644 fish-rust/src/builtins/string/length.rs create mode 100644 fish-rust/src/builtins/string/match.rs create mode 100644 fish-rust/src/builtins/string/pad.rs create mode 100644 fish-rust/src/builtins/string/repeat.rs create mode 100644 fish-rust/src/builtins/string/replace.rs create mode 100644 fish-rust/src/builtins/string/shorten.rs create mode 100644 fish-rust/src/builtins/string/split.rs create mode 100644 fish-rust/src/builtins/string/sub.rs create mode 100644 fish-rust/src/builtins/string/transform.rs create mode 100644 fish-rust/src/builtins/string/trim.rs create mode 100644 fish-rust/src/builtins/string/unescape.rs create mode 100644 fish-rust/src/builtins/tests/string_tests.rs delete mode 100644 src/builtins/string.cpp delete mode 100644 src/builtins/string.h delete mode 100644 src/re.cpp delete mode 100644 src/re.h diff --git a/CMakeLists.txt b/CMakeLists.txt index 1e2112f38..bc91c5003 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -107,7 +107,7 @@ set(FISH_BUILTIN_SRCS src/builtins/jobs.cpp src/builtins/path.cpp src/builtins/read.cpp src/builtins/set.cpp src/builtins/source.cpp - src/builtins/string.cpp src/builtins/ulimit.cpp + src/builtins/ulimit.cpp ) # List of other sources. @@ -121,7 +121,7 @@ set(FISH_SRCS src/null_terminated_array.cpp src/operation_context.cpp src/output.cpp src/pager.cpp src/parse_execution.cpp src/parse_util.cpp src/parser.cpp src/parser_keywords.cpp src/path.cpp src/postfork.cpp - src/proc.cpp src/re.cpp src/reader.cpp src/screen.cpp + src/proc.cpp src/reader.cpp src/screen.cpp src/signals.cpp src/utf8.cpp src/wcstringutil.cpp src/wgetopt.cpp src/wildcard.cpp src/wutil.cpp src/fds.cpp src/rustffi.cpp diff --git a/fish-rust/src/abbrs.rs b/fish-rust/src/abbrs.rs index 4eb967aca..9ce84161d 100644 --- a/fish-rust/src/abbrs.rs +++ b/fish-rust/src/abbrs.rs @@ -18,7 +18,6 @@ #[cxx::bridge] mod abbrs_ffi { extern "C++" { - include!("re.h");

Previously `fish_wcswidth` returned a length of -1 when the ellipsis-str contained any non-printable character, causing the command to poentially print a larger width than expected. This also fixes an integer overflows in `string shorten`'s `max` and `max2`, when the cumulative sum of character widths turned negative (e.g. with any non-printable characters, or `\b` after the changes above). The overflow potentially caused strings containing non-printable characters to be truncated. This adds test that verify the fixed behaviour. --- CHANGELOG.rst | 2 + fish-rust/src/builtins/string.rs | 7 +- fish-rust/src/builtins/string/length.rs | 4 +- fish-rust/src/builtins/string/pad.rs | 37 +++++----- fish-rust/src/builtins/string/shorten.rs | 68 +++++++++--------- tests/checks/string.fish | 92 ++++++++++++++++++++++++ 6 files changed, 151 insertions(+), 59 deletions(-) diff --git a/CHANGELOG.rst b/CHANGELOG.rst index 417c47b94..9d11cfdba 100644 --- a/CHANGELOG.rst +++ b/CHANGELOG.rst @@ -51,6 +51,8 @@ Other improvements - A bug that prevented certain executables from being offered in tab-completions when root has been fixed (:issue:`9639`). - Builin `jobs` will print commands with non-printable chars escaped (:issue:`9808`) - An integer overflow in `string repeat` leading to a near-infinite loop has been fixed (:issue:`9899`). +- `string shorten` behaves better in the presence of non-printable characters, including fixing an integer overflow that shortened strings more than intended.

As a result we end up building the Rust-libraries for the default target, which is usually current macOS-version. But CMake links using the set target, so we link for a version older than we built for. To properly build for older macOS versions, the env variable `MACOSX_DEPLOYMENT_TARGET` should instead be set, which cargo, cmake and friends read by default. This can then lead to warnings if you have libraries (e.g. PCRE2) built for newer than our minimum version.

For context, Rust by default uses SipHash 1-3 https://github.com/rust-lang/rust/commit/db1b1919baba8be48d997d9f70a6a5df7e31612a An alternative would be to store it as raw pointers aka `*const T`, which have a cheaper hash impl. That has a more complicated implementation + removes lifetimes. This commit rather removes the premature optimization.

Neither of which is *super* useful, I admit, but we've picked one and the docs shouldn't contradict it. --- doc_src/cmds/path.rst | 4 ---- 1 file changed, 4 deletions(-) diff --git a/doc_src/cmds/path.rst b/doc_src/cmds/path.rst index bf764839c..ff819af92 100644 --- a/doc_src/cmds/path.rst +++ b/doc_src/cmds/path.rst @@ -365,19 +365,15 @@ Examples >_ path change-extension '' ../banana ../banana - # but status 1, because there was no extension. >_ path change-extension '' ~/.config /home/alfa/.config - # status 1 >_ path change-extension '' ~/.config.d /home/alfa/.config - # status 0 >_ path change-extension '' ~/.config. /home/alfa/.config - # status 0 "sort" subcommand ----------------------------- From 05c44df1a49d903450f592b8d46ded8db2b55622 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Henrik=20H=C3=B8rl=C3=BCck=20Berg?= <36937807+henrikhorluck@users.noreply.github.com> Date: Thu, 24 Aug 2023 16:11:40 +0200 Subject: [PATCH 816/831] Run `cargo fmt` with Rustfmt 1.6.0 - "1.6.0" now supports formatting let-else statements which we use liberally, and appears to have some fixes in regards to long-indented-lines with macros like `wgettext_ft!` - This commit updates the formatting so that devs with the latest stable don't see random format-fixes upon running `cargo fmt` --- fish-rust/src/builtins/bg.rs | 6 +++--- fish-rust/src/builtins/emit.rs | 4 +++- fish-rust/src/builtins/function.rs | 6 +++++- fish-rust/src/builtins/status.rs | 14 +++++++++++--- fish-rust/src/path.rs | 8 ++++++-- fish-rust/src/tests/string_escape.rs | 3 ++- fish-rust/src/wchar_ext.rs | 4 +++- fish-rust/src/wutil/mod.rs | 4 +++- 8 files changed, 36 insertions(+), 13 deletions(-) diff --git a/fish-rust/src/builtins/bg.rs b/fish-rust/src/builtins/bg.rs index acac4d8d8..7e0bf2056 100644 --- a/fish-rust/src/builtins/bg.rs +++ b/fish-rust/src/builtins/bg.rs @@ -73,9 +73,9 @@ pub fn bg(parser: &mut parser_t, streams: &mut io_streams_t, args: &mut [&wstr]) let Some(job_pos) = job_pos else { streams - .err - .append(wgettext_fmt!("%ls: There are no suitable jobs\n", cmd));
