This would break the location of any prior errors without doing
anything of value.
E.g.
```fish
echo foo | exec grep # this exec is not allowed!
$status
somethingelse # The error might be found here!
```
Would apply the offset of `$status` to the offset of `exec`, locating
the error for `exec` somewhere after $status!
Allows the compiler to know our bespoke assert functions
are cold paths. This would normally occur somehow for real assert().
Assembly does appear it will save some branches.
Also don't worry about NDEBUG
(This doesn't matter because we rolled our own assert functions.
Thanks @zanchey.)
sphinx-build supports the -j option to use multiple processes. Start using
it. This reduces the time to build the docs on my Linux box from 11 seconds
to about 4.
Note this doesn't work on macOS since -j is ignored there (see sphinx-build
PR 6879).
Prior to this change, tmux based tests would call 'isolated-tmux' which would
initialize tmux on first call, an admitted "evil hack." Switch to requiring
an explicit call to 'isolated-tmux-start' which then defines 'isolated-tmux'
and other functions. Add some loop-until-prompt logic into
'isolated-tmux-start'. This improves reliability of the tmux tests on systems
under load; at least it makes the tests pass in the background on my Mac.
Remove the '$sleep' variable, to be replaced with 'tmux-sleep'.
Just guess anew when it's not set.
(this still uses the value of $fish_emoji_width, but clamped to 1 or 2
- we could also guess if it's an unusable value, but that's a
different issue and tbh this variable is becoming less and less useful
as time moves on and things move to the new widths by default)
Fixes#8274.
This is weirdly undocumented (as of git 2.33.0), but `git status` prints a "T" state if
the file has its "T"ype changed, e.g. from a regular file to a symlink.
For our purposes that's just another kind of modification.
Fixes#8311.
This makes it so we treat backspaces as width -1, but never go below a
0 total width when talking about *lines*, like in screen or string
length --visible.
Fixes#8277.
* Hide whatis database building from the user
It's really an internal detail, but shows up in prompts that display how many
background jobs are running.
By disowning it keeps running but won't show up in `jobs` or get killed if the user
exits the shell.
* Update __fish_apropos.fish
OpenBSD has a posix_spawn implementation which fails to return ENOEXEC
on a shebangless script, causing us to fail the shebangless tests.
Disable posix_spawn on OpenBSD.
OpenBSD's mmap is famously unsychronized with file IO. In theory fsync
and msync can be used to synchronize but I was unable to get it to work.
Just don't use mmap for history on OpenBSD. This fixes the history merge
tests.
When getting the hostname to construct the legacy uvar path, if the
hostname is empty, we will create a path pointing at a directory. On
BSDs this path can be successfully open'd and we will produce errors
about invalid uvar files.
