This is a little script that can be run manually to try and detect ODR
violations. It works by looking for weak symbols in .o files where the
symbol has the same name and different sizes.
Also for the glob version, because this is just a performance thing.
Makes `echo **` 20% faster - 100ms to 80ms for the fish repo.
This also applies to the future `path` builtin.
Still not a speed demon, but this is a very very easy win.
Now we probably gotta do globbing all in string instead of wcs2stringing ourselves to death.
Like the $status commit, this would add the offset to already existing
errors, so
```fish
(foo)
(bar)
something
```
would see the "(foo)" error, store the correct error location, then
see the "(bar)" error, and *add the offset of (bar)* to the "(foo)"
error location.
Solve this by making a new error list and appending it to the existing
ones.
There's a few other ways to solve this, including:
- Stopping after the first error (we only display the first anyway, I
think?)
- Making it so the source location has an "absolute" flag that shows
the offset has already been added (but do we ever need to add two offsets?)
I went with the simpler fix.
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.
