OSC 133 was added to tmux 3.4.
Also fix the test on macOS where we do have 3.5a in CI; for some reason we
get copy_cursor_y=6 there. I didn't investigate yet but at least that's
not the same bug this test was made to fix.
For multi-line prompts, we start each leading line with a clr_eol. Immediately
before printing these prompt lines we emit the OSC 133 prompt start marker.
Some terminals such as tmux interpret make clr_eol delete such markers,
hence prompt navigation is broken.
Fix this by printing the marker only after clr_eol.
The scenario where this triggers is quite odd. I haven't looked into why
the problem doesn't exist if I remove the recursive repaint request.

Our panic handler attempts a blocking read from stdin and only exits
after the user presses Enter.
This is unconventional behavior and might cause surprise but there is a
significant upside: crashes become more visible for terminals that don't
already detect crashes (see ecdc9ce1d (Install a panic handler to avoid
dropping crash stacktraces, 2024-03-24)).
As reported in 4d0aa2b5d (Fix panic handler, 2024-08-28), the panic handler
failed to exit fish if the panic happens on background threads. It would
only exit the background thread (like autosuggestion/highlight/history-pager
performer) itself. The fix was to abort the whole process.
Aborting has the additional upside of generating a coredump.
However since abort() skips stack unwinding, 4d0aa2b5d makes us no longer
restore the terminal on panic. In particular, if the terminal supports kitty
progressive enhancements, keys like ctrl-p will no longer work in say,
a Bash parent shell. So it broke 121680147 (Use RAII for restoring term
modes, 2024-03-24).
Fix this while still aborting to create coredumps. This means we can't use
RAII (for better or worse). The bad part is that we have to deal with added
complexity; we need to make sure that we set the AT_EXIT handler only after
all its inputs (like TERMINAL_MODE_ON_STARTUP) are initialized to a safe
value, but also before any damage has been done to the terminal. I guess we
can add a bunch of assertions.
Unfortunately, if a background thread panics, I haven't yet figured out how
to tell the main thread to do the blocking read. So the trick of "Press
Enter to exit", which allows users to attach a debugger doesn't yet work for
panics in background threads. We can probably figure that out later. Maybe
use pthread_kill(3)? Of course we still create coredumps, so that's fine.
As a temporary workaround, let's sleep for a bit so the user can at least
see that there is a crash & stacktrace.
One ugly bit here is that unit tests run AT_EXIT twice but it should be
idempotent.
I don't think I really get why this newline is here. It moves the cursor
from the end of the newline to the beginning of the next line. Maybe it
was added only for panics in background threads? Either way it's fine.
We don't care to check the latest value of these variables;
these should only be read on startup and are not meant to
be overridden by the user ever. Hence we don't need a parser.
If SIGTERM is delivered to a background thread, a function call to sanitize
the reader state would crash in assert_is_main_thread(). In this case we
are about to exit so there's no need to fix the reader state. Skip it on
background threads.
Users may install two versions of fish and configure their terminal to run
the one that is second in $PATH. This is not really what I'd do but it
seems reasonable. We should not need $PATH for this.
Fixes#10770
We use optimistic concurrency when rewriting the history file to
minimize the lock scope. Unfortunately, old.mtime == new.mtime
does not imply that file is unchanged; we don't have guarantees
on the granularity of the modification time timestamp, see
https://stackoverflow.com/questions/14392975/timestamp-accuracy-on-ext4-sub-millsecond
So let's lock before reading any old contents and use the other
"write-to-tempfile-and-rename" code path only when locking fails.
Potentially fixes#10300
(untested) which probably happens because read_zero_padded() attempts to
read bytes that have not been flushed yet.
No functional change, since with the parent commit, we no longer treat
"DirRemoteness::local" different from "DirRemoteness::remote", but we might
do so in future, so make sure we don't give a false positive here.
Non-Linux systems have ST_LOCAL or MNT_LOCAL, so no unknowns there.
See #10434
mmap() fails with ENODEV on remote file systems. This means we always fail
to read any old history on network file systems on Linux (except on the file
systems we recognize which are NFS, SMB and CIFS).
Untested, so I'm not sure if this works.
Fixes#10434
We no longer use RAII for enabling/disabling these, so a full object is
overkill. Additionally this object doesn't allow us to recover from the case
where we receive SIGTERM while inside terminal_protocols_{enable,disable}.
We can simply run disable another time since they're idempotent. Untested.
When I run a command with leading space, it is not added to the on-disk
history. However we still call History::save(). After 25 of such calls,
we rewrite the history file (even though nothing was written by us).
This is annoying when diagnosing #10300 where the history of the current
shell (but not other shells) is broken; because the history rewrite will
make the problem go away. Let's not save in this case, to make it easier to
run commands to inspect the state of the history file.
Commit 4e79ec5f tried to restore the static PCRE2 build after the update to the
pcre2 crate, but it set an environment variable at configure time, not build
time.
Properly set the environment variable at build time.
Given a history like
- cmd: echo OLD
when: 1726157160
\x00\x00\x00- cmd: echo leading NUL bytes
when: 1726157160
- cmd: echo NEW
when: 1726157223
offset_of_next_item() happily records 3 items even though the second item
is corrupted.
decode_item() fails which makes the caller stop loading any older items --
we got knee capped.
Avoid this horrible failure mode by skipping over these items already in
offset computation. For now we still lose the corrupted item itself.
In future we should probably try to delete the NUL bytes or avoid the
corruption in the first place.
See #10300 and others.
This should make the sort have a strict weak ordering, which rust
requires since 1.81 (or it will panic).
Note: This changes the order, but that's *fine* since the current
order is random weirdness anyway.
Fixes#10763
This was overly smart and tried to not show you e.g. global variables
unless you were setting without scope or explicitly global.
That is annoying when you do
`set -g fish_col<TAB>`
and don't get colors because they're universal, but you could
overwrite them.
We *could* elide e.g. local variables if we're setting a global, but I
can see someone wanting to set a universal variable on basis of a
global ("save this"), so I would rather not try to find the very
specific cases where this works.
1. Leave the indentation
2. Leave the "NAME" header - without the first line would be
unindented
3. Leave the "SYNOPSIS" header
We use $MANPAGER here, so it should be formatted like a manpage.
The alternative is to write special docs for this use-case, which
would be shorter and point towards the full man page.
Fixes#10625
They are already presented in normal mode, and I presume were forgotten to be
added in visual mode
I don't add it to ./CHANGELOG.rst because it's a minor change that can be
considered as a bug fix
The recent update to the rust-pcre2 crate lost the property where a static
PCRE2 build could be enabled with a Cargo feature. This means that static
PCRE2 builds can no longer be forced.
Switch to setting the "PCRE2_SYS_STATIC" variable again, which is how the
official rust-pcre2 crate expects to work.
Commit c921c124e (docs: use canonical key names in :kbd: tags, 2024-04-13)
removed the box highlighting from elements like :kbd:`ctrl-c`.
This is because Sphinx for some reason converts this into
<kbd>
<kbd>ctrl</kbd>
-
<kbd>c</kbd>
</kbd>
which results in duplicate boxes.

Our current style looks a bit ugly (it's
definitely worse than github's rendering at
https://github.com/fish-shell/fish-shell/blob/master/CHANGELOG.rst).
Let's restore the old style but make sure to only apply it only to the
outermost kbd element.
While at it, use the same monospace font as for inline code.
Commit b00899179 (Don't indent multi-line quoted strings; do indent inside
(), 2024-04-28) made parse_util_compute_indents() crash on `echo "$()"'x`.
After recursively indenting the command substitution, we indent the "'x
suffix. We skip the quoted part by setting "done=2". Later we wrongly
index "self.indents[done..range.start+offset+1]" (= "self.indents[2..1]").
Fix this by making sure that "start >= done", thus not setting any indents
for the quoted suffix. There is no need to do so; only the first character
in each line needs an indent.
In particular, this fixes the case
ctrl-r foo ctrl-r
where foo substring-matches no more than one page's worth of results.
The second attempt will fall back to subsequence matching which is wrong.
