c1fba4663b Replace nanosleep with stdlib wrapper (which is still broken)
As of rust 1.78, the Unix stdlib implementation is affected by the same issue:

    pub fn sleep(dur: Duration) {
        let mut secs = dur.as_secs();
        let mut nsecs = dur.subsec_nanos() as _;

        // If we're awoken with a signal then the return value will be -1 and
        // nanosleep will fill in `ts` with the remaining time.
        unsafe {
            while secs > 0 || nsecs > 0 {
                let mut ts = libc::timespec {
                    tv_sec: cmp::min(libc::time_t::MAX as u64, secs) as libc::time_t,
                    tv_nsec: nsecs,
                };
                secs -= ts.tv_sec as u64;
                let ts_ptr = core::ptr::addr_of_mut!(ts);
                if libc::nanosleep(ts_ptr, ts_ptr) == -1 {
                    assert_eq!(os::errno(), libc::EINTR);
                    secs += ts.tv_sec as u64;
                    nsecs = ts.tv_nsec;
                } else {
                    nsecs = 0;
                }
            }
        }
    }

Note that there is a small behavior change here -- sleep() will continue
after signals; I'm not sure if we want that but it seems harmless?

7cfc6297bc Hack to make alt-{left,right} work again in iTerm2
iTerm2 deviates from protocol, so back out c3c832761 (Stop using stack for
kitty progressive enhancement, 2024-08-03) in that case.

Note that we use several ways of detecting iTerm2 (ITERM_PROFILE,
TERM_PROGRAM=iTerm.app, ITERM_SESSION_ID).
LC_TERMINAL seems superior because it works over ssh.

This new one should hopefully go away eventually.

c3c8327610 Stop using stack for kitty progressive enhancement
Today fish pushes/pops kitty progressive enhancements everytime control is
transfered to/from fish. This constitutes a regression relative to 3.7.1:

    $ fish
    $ ssh somehost fish
    (network disconnect, now we missed our chance to pop from the stack)
    $ bash # or some ncurses application etc
    (keyboard shortcuts like ctrl-p are broken)

When invoking bash, we pop one entry off the stack but there is another one.
There seems to be a simple solution: don't use the stack but always reset
the current set of flags.  Do that since I did not find a strong use case
for using the stack[1] (Note that it was recommended by terminal developers
to use the stack, so I might be wrong).

Note that there is still a regression if the outer shell is bash.

041a26f647 Update TTY modes for external commands only after successful command
According to the discussion in #2315, we adopt TTY modes for external commands
mainly for "stty".  If our child process crashes (or SSH disconnect), we
might get weird modes. Let's ignore the modes in the failure case.

e25a1358e6 Work around broken rendering of pasted multibyte chars in non-UTF-8-ish locale
Run

    printf \Xf6 | wl-copy # ö in ISO-8859-1
    LANG=de_DE LC_ALL=$LANG gnome-terminal -- build/fish

and press ctrl-v. The pasted data looks like this:

    $ set data (wl-paste -n 2>/dev/null | string collect -N)
    $ set -S data
    $data: set in local scope, unexported, with 1 elements
    $data[1]: |\Xf6|

we pass $data directly to "commandline -i", which is supposed to insert it
into the commandline verbatim. What's actually inserted is "�".

This is because of all of:
1. We never decode "\Xf6 -> ö" in this scenario. Decoding it -- like we do
   for non-pasted keyboard input -- would fix the issue.
2. We've switched to using Rust's char, which, for better or worse, disallows
   code points that are not valid in Unicode (see b77d1d0e2 (Stop crashing
   on invalid Unicode input, 2024-02-27)). This means that we don't simply
   store \Xf6 as '\u{00f6}'. Instead we use our PUA encoding trick, making it
   \u{f6f6} internally.
3. Finally, b77d1d0e2 renders reserved codepoints (which includes PUA chars)
   using the replacement character � (sic).  This was deemed more
   user-friendly than printing an invalid character (which is probably not
   mapped to a glyph).  Yet it causes problems here: since we think that
   \u{f6f6} is garbage, we try to render the replacement character. Apparently
   that one is not defined(?) in ISO-8859-1; we get "�".

Fix this regression by removing the replacement character feature.

In future we should maybe decode pasted input instead. We could do that
lazily in "commandline -i", or eagerly in "set data (wl-paste ...)".

d21ed0fb22 Disable terminal protocols before expanding wildcards
Commit 29f2da8d1 (Toggle terminal protocols lazily, 2024-05-16) made it so
the wildcard expansion in "echo **" (in a large directory tree) can't be
canceled with ctrl-c.  Fix this by disabling terminal protocols already at
expansion time (not waiting until execution).

3be588569d Disable CSI u inside Midnight Commander for now
Using

    SHELL=$(command -v fish) mc

Midnight Commander will spawn a fish child with

    "function fish_prompt;"
    "echo \"$PWD\">&%d; fish_prompt_mc; kill -STOP %%self; end\n",

So fish_prompt will SIGSTOP itself using an uncatchable signal.

On ctrl-o, mc will send SIGCONT to give back control to the shell.
Another ctrl-o will be intercepted by mc to put the shell back to sleep.

Since mc wants to intercept at least ctrl-o -- also while fish is in control
-- we can't use the CSI u encoding until mc either understands that, or uses
a different way of passing control between mc and fish.

Let's disable it for now.

Note that mc still uses %self but we've added a feature flag
to disable that.  So if you use "set fish_features all"
you'll want to add a " no-remove-percent-self". A patch
to make mc use $fish_pid has been submitted upstream at
https://lists.midnight-commander.org/pipermail/mc-devel/2024-July/011226.html.

Wildcard tree walking to only rely on dev, inode to detect changes
When applying a wildcard, it's important to keep track of the files that have
been visited, to avoid symlink loops. Previously fish used a FileId for the
purpose. However FileId also includes richer information like modification time;
thus if a file is modified during wildcard expansion then fish may believe that
the file is different and visit it twice.

The richer information like modification time is important for atomic file
writes but should be ignored for wildcard expansion; just use the (dev, inode)
pair instead.

This also somewhat reduces our reliance on struct stat, but we still need it for
fstatat which Rust does not expose.

93f8385448 Add option to speed up string match/replace with --max-matches
I've often needed a way to get the last bit of performance out of unwieldy
completions that involve a lot of string processing (apt completions come to
mind, and I ran into it just now with parsing man pages for kldload
completions).

Since many times we are looking for just one exact string in the haystack, an
easy optimization here is to introduce a way for `string match` or `string
replace` to early exit after a specific number of matches (typically one) have
been found.

Depending on the size of the input, this can be a huge boon. For example,
parsing the description from FreeBSD kernel module man pages with

    zcat /usr/share/man/man4/zfs.4.gz | string match -m1 '.Nd *'

runs 35% faster with -m1 than without, while processing all files under
/usr/share/man/man4/*.4.gz in a loop (so a mix of files ranging from very short
to moderately long) runs about 10% faster overall with -m1.

Implement jump-till-matching-bracket input function
Part of #1842

It's like jump-to-matching-bracket, but jumps right before the bracket

I will use it to mimic vi 'ab' and 'ib' text objects in the next commit

Given complicated semantics of jump-till-matching-bracket, an alternative name
could be 'jump-inside-matching-brackets'. But that would make names non-symmetrical.

0adebdfbc4 Fix completely broken __fish_describe_command integration
Command completion descriptions were not being generated from `apropos`. Well,
they were being generated but that was not being correctly used by fish core.

Not sure when this was broken, but there's a possibility it was during the rust
port.

In addition to simply not working, it seems the old code tried to avoid
allocations but String::split_at_mut() allocates a new string (since one
allocation from the global allocator can't be split into two allocations to be
freed separately). Use `String::as_mut_utfstr()` before splitting the &wstr
instead of splitting the &str to actually do this alloc-free.

Split Reader off from ReaderData
Prior to this commit, there was a stack of ReaderDatas, each one has a
reference to a Parser (same Parser in each, for now). However, the current
ReaderData is globally accessible. Because it holds a Parser, effectively
anything can run fish script; this also prevents us from making the Parser
&mut.

Split these up. Create ReaderData, which holds the data portion of the
reader machinery, and then create Reader which holds a ReaderData and a
Parser. Now `reader_current_data()` can only return the data itself; it
cannot execute fish script.

This results in some other nice simplifications.

Migrate the Inputter type to a trait
This is a start on untangling input. Prior to this, a ReaderData and an
Inputter would communicate with each other; this is natural in C++ but
difficult in Rust because the Reader would own an Inputter and therefore
the Inputter could not easily reference the Reader. This was previously
"resolved" via unsafe code.

Fix this by collapsing Inputter into Reader. Now they're the same object!
Migrate Inputter's logic into a trait, so we get some modularity, and then
directly implement the remaining input methods on ReaderData.

1d159277c6 Move Block fields specific to certain block types to separate enum
This has a few advantages,
* We now statically assert that all fields used by a particular block type are
  correctly initialized (i.e. you can't assign the function name but forget to
  assign its arguments),
* Conversely, we can match directly on `BlockData` and be guaranteed that the
  fields we want to access are initialized and present,
* We reduce the number of assertions, effectively "unwrapping" only once based
  off the block type instead of each time we try to access a conditional field,
* We reduce the size of the `Block` struct by coalescing fields that cannot
  co-exist, bringing it down from 104 bytes to 88 bytes.

It would be nice to make all of `Block` itself an enum, but it currently
requires `Copy` and we take advantage of that to copy it around everywhere.
Putting these fields directly in `Block` directly would mean a lot more memory
traffic just checking block types.

7bf3b57e47 Fix buggy test_pthread() condvar test
There's no guarantee that a condition variable is stateful. The docs for
`Condvar::notify_one()` actually say the opposite:

> If there is a blocked thread on this condition variable, then it will be woken
> up from its call to wait or wait_timeout. Calls to notify_one are not buffered
> in any way.

This test was relying on the main loop obtaining the lock and entering the
condition variable sleep before the thread was scheduled and got around to
notifying the condition variable. If this non-deterministic behavior was not
upheld, the test would time out since it would obtain the lock (either before or
after the variable were updated) then call `condvar.wait()` *after* the variable
had been updated and the condvar signalled, but without (atomically or even at
all) checking to see if the desired wake precondition was fulfilled. As the
child thread had already run and the wake notification was NOT buffered, there
was nothing to wake the running thread.

There really wasn't any way to salvage the test as originally written, since the
write to `ctx.val` was not in any way linked to the acquire/release of the mutex
so regardless of whether or not the main thread obtained the mutex and checked
the value precondition before calling `condvar.wait()`, the child thread's write
could have happened after the check but before the wait() call. As such, the
test has been rewritten to use `wait_while()` but then also updated to bail in
case of a timeout instead of hanging indefinitely (since neither the `ctest`
runner nor the `cargo test` harness was timing out; `cargo test` would only
report that the test had exceeded 60 seconds but as long as it was not executed
with `cargo test -- -Z --ensure-time` (which is only available under nightly),
the test would not halt.

If this test were *intentionally* written to test the scenario that was timing
out, it should be written deterministically in such a way that the main loop
did not run until after it was guaranteed that the variable had been updated
(i.e. by looping until val became 5 or waiting for an AtomicBool indicating the
update had completed to be set), but I'm not sure what the benefit in that would
be since the docs actually guarantee the opposite behavior (the notified state
is explicitly not cached/buffered).

If we have fish code written with the assumption that condvar notifications
prior to *any* call to `Condvar::wait()` *are* buffered, then that code should
of course be revisited in light of this.

8c62f733b3 Extend certain WSL workarounds to WSLv2
This updates is_windows_subsystem_for_linux() to take a WSL version to test for
(any, v1, or v2) and returns the boolean result depending on the system. I've
benchmarked and when running on regular Linux, this is still just as fast as the
previous binary check; it's only when it's WSL that this takes about 20ns
longer to figure out which variant.

Note that older WSLv2 kernels had a `-microsoft-standard` suffix while newer
ones appear to have a `-microsoft-standard-WSL2` suffix, so we make sure to test
for the least common denominator. (It doesn't matter to us, but note that newer
WSLv2 kernels have four dots in the version string!)

WSL workarounds pertaining to the default Windows terminal or executable
behavior of win32 binaries under a WSL shell are extended to WSLv2 while those
specific to oddities in kernel behavior are confined to WSLv1 only. (It
technically wouldn't hurt to extend them to WSLv2 but there's no good reason to
do so, either.)

Work around $PATH issues under WSL (#10506)
A common complaint has been the massive amount of directories Windows appends to
$PATH slowing down fish when it attempts to find a non-existent binary (which it
does a lot more often than someone not in the know might think). The typical
workaround suggested is to trim unneeded entries from $PATH, but this a) has
considerable friction, b) breaks resolution of Windows binaries (you can no
longer use `clip.exe`, `cmd.exe`, etc).

This patch introduces a two-PATH workaround. If the cmd we are executing does
not contain a period (i.e. has no extension) it by definition cannot be a
Windows executable. In this case, we skip searching for it in any of the
auto-mounted, auto-PATH-appended directories like `/mnt/c/Windows/` or
`/mnt/c/Program Files`, but we *do* include those directories if what we're
searching for could be a Windows executable. (For now, instead of hard-coding a
list of known Windows executable extensions like .bat, .cmd, .exe, etc, we just
depend on the presence of an extension at all).

e.g. this is what starting up fish prints with logging enabled (that has been
removed):

    bypassing 100 dirs for lookup of kill
    bypassing 100 dirs for lookup of zoxide
    bypassing 100 dirs for lookup of zoxide
    bypassing 100 dirs for lookup of fd
    not bypassing dirs for lookup of open.exe
    not bypassing dirs for lookup of git.exe

This has resulted in a massive speedup of common fish functions, especially
anywhere we internally use or perform the equivalent of `if command -q foo`.

Note that the `is_windows_subsystem_for_linux()` check will need to be patched to
extend this workaround to WSLv2, but I'll do that separately.

Under WSL:
* Benchmark `external_cmds` improves by 10%
* Benchmark `load_completions` improves by an incredible 77%

because for "fzf", ParseExecutionContext::setup_group() returns early with the
parent process group (which should be fish's own) , hence "wants_terminal"
is false. This seems questionable, I don't think the eval should make a
difference here.

For now, don't touch it; use the more accurate way of detecting whether
a process may read keyboard input. In many of such cases "wants_terminal"
is false, like

0f18480559 Simplify Parser and EnvStack singletons and clarify thread semantics
`Parser` is a single-threaded `!Send`, `!Sync` type and does not need to use
`Arc` for anything. We were using it because that's all we had for the parser's
`EnvStack`, but though that is *technically* protected internally by a mutex
(shared with global EnvStack), there's nothing to say that other parsers with a
narrower scope/lifetime on other threads will be necessarily using the same
backing mutex.

We can safely marshal the existing `Arc<EnvStack>` we get from
`environment::principal()` into an `Rc<EnvStack>` since the underlying reference
is always valid. To prove this point, we could have PRINCIPAL_STACK be a static
`EnvStack` and have `environment::principal()` use `Arc::from_raw()` to turn
that into an `Arc<EnvStack>`, but there's no need to factorize this process.

b82170aded Change extract_prefix_and_unescape_yaml() assert!() to debug_assert!()
It's reasonable since this is only checking to see that the history file
contains the expected format and if it's corrupted but we at least got what we
expect to be the correct key/value pairs, then that's all we can do.

Of course the real motivation is to speed up this very hot function in any way
possible!

51275525c1 Speed up extract_prefix_and_unescape_yaml
On the completions and history thread, the parent function
HistoryFileContents::decode_item() is responsible for ~60% of the CPU time, and
extract_prefix_and_unescape_yaml() alone comprising 14% (of the total).

This change removes allocations in the event that the history item is either
fully or partially plain yaml with no escapes to begin with, and brings down the
execution time of this function to only 7% of the total execution time.

The bulk of the remaining time is spent in wcs2string(), which is called
unconditionally and is naturally alloc-heavy.

f1e19884fb Add set --no-event
This allows running `set` without triggering any event handlers.

That is useful, for example, if you want to set a variable in an event
handler for that variable - we could do it, for example, in the
fish_user_path or fish_key_bindings handlers.

This is something the `block` builtin was supposed to be for, but it
never really worked because it only allows suppressing the event for
the duration, they would fire later. See #9030.

Because it is possible to abuse this, we only have a long-option so
that people see what is up.

a19ff4989a Prevent out-of-order execution following repaint
Commit a583fe723 ("commandline -f foo" to skip queue and execute immediately,
2024-04-08) fixed the execution order of some bindings but was partially
backed out in 5ba21cd29 (Send repaint requests through the input queue again,
2024-04-19) because repainting outside toplevel yields surprising results
(wrong $status etc).

Transient prompts wants to first repaint and then execute some more readline
commands, all within a single binding.  This was broken by the second commit
because that one defers the repaint until after the binding has finished.

Work around this problem by deferring input events again while a readline
event was queued. This is closest to the historical behavior.

The implementation feels hacky; we might find odd situations.
For example,

    commandline -f repaint end-of-line
    set token (commandline -t)

sets the wrong token.
Probably not a very important case. We could throw an error or make it work
by letting "commandline -t" drain the input queue.

That seems too complicated, better change repaints to not use the input queue
(and fake $status etc). Let's try to do that in future.

35a16e3713 Rename FISH_TSAN_WORKAROUNDS and add feature to Cargo.toml
rustc 1.80 now complains about features not declared in Cargo.toml and cfg
keys/values not declared by build.rs to protect against typos or misuse (you
think you're using the right condition but you're not). See
rust-lang/cargo#10554 and rust-lang/rust#82450.

(We're not actually using TSAN under CI at this time, but I do want to re-enable
it at some point — especially if we get multithreaded execution going — using
the rust-native TSAN configuration.)

I'll be updating the `rsconf` crate and patching `build.rs` accordingly to also
handle the warnings about unknown cfg values, but tsan is a feature and not a
cfg and these can be dealt with in `Cargo.toml` directly.

twice for each `n` in the 3-digit case, causing unnecessary repeated parsing of
individual characters into their radix-16 numeric equivalents, which could be
avoided just by reusing the already calculated result.

a126d2aeba Revert "Remove redundant default escape delay"
I think given a local terminal running fish on a remote system, we can't
assume that an input sequence like \ea is sent all in one packet. (If we
could that would be perfect.)

Let's readd the default escape delay, to avoid a potential regression, but
make it only apply to raw escape bindings like "bind \e123". Treat sequences
like "bind escape,1,2,3" like regular sequences, so they can be bound on
all terminals.

This partially reverts commit b815319607.

Given "abbr foo something", the input sequence
