- Only check for HAVE_CLOCK_GETTIME and HAVE_FUTIMENS on Linux, since
they are only used to implement a Linux-specific workaround related
to mtime precision.
- Make sure that hack is limited to Linux builds
- HAVE_SYS_SYSCTL_H was unused, but we should have been using it
- HAVE_TERMIOS_H was unused, remove it
The only functional change is that unix machines with clock_gettime
and futimens will not bother with a Linux-specific hack, and won't
waste time checking for either during cmake configuration either.
For some godforsaken reason it's slow on glibc
Like, actually, this manages to somehow make "echo **" 10% faster now?
The spec says this matches 0 through 9 always, so this is safe. We
also use this logic in a variety of other places already.
This allows us to skip re-wcs2stringing the base_dir again and again
by simply using the fd. It's about 10% faster in my testing.
fstatat is defined by POSIX, so it should be available everywhere.
Revert the change getting rid of the -UNDEBUG, add some unused-blah
warnings.
We are often using the system assert() because we include other
headers that include assert.h.
I noticed that assert() was being compiled out because I started
getting new warnings printed about unusued variables (that were only
used in the assert()s. Add these warnings to the build.
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'.
