__GLIBC_PREREQ is the preferred way to conditionally enable features
based on glibc versions. Use it to avoid expensive parsing and
locale sensitivity. See #8204
If $xdg_chache_home is empty, this is not a valid fish expression:
[ \( -z \) -o \( ! -d \) ]
and results into an error.
While at it, also use $XDG_CACHE_HOME if that directory does not exist.
This seems better than falling back to $HOME/.cache, which the user has
explicitly overridden via $XDG_CACHE_HOME.
Usually local branches have remote branches with the same name, and in
completion they are currently overshadowed by unique remote branches, making
local branches hard to find. Define local branch completion after unique
remote branch completion to show local branches before unique remote branches.

We want to enable posix_spawn only for glibc >= 2.24, so we check
gnu_get_libc_version() at runtime. This returns a string with the
version number.
Because it's a version number it's spelt with a "." and never a ",",
but we interpret it as a float. This is iffy to begin with, but simple
enough. Only when the locale uses a ",", things break - it'll read it
as "2" and fail the check, which absolutely *tanks* performance on WSL1.
I'm unsure if this gives the proper runtime glibc version - it might,
whereas __GLIBC_MINOR__ and such definitely would not.
So fix the immediate problem by at least using a c locale - this is
already masked by 8dc3982408, but better
safe than sorry.
In 'simple terminal' the delete key prints \e[P by default, which is
related to the different approach the authors of st are taking on the
matter of shell configuration. The main problem is the malfunction of
the delete key, so we have to use a workaround like this.
In most cases, like math, we want C-semantics for floating point
numbers. In particular "." needs to be the decimal separator.
Instead, we pay the price in printf, which is currently the sole place
to output in locale-specific numbers and attempt to read them and
C-style ones.
Similar to `test`, `_` is so likely to at least slow down if not
break all things catastrophically that it ought not be allowed as a
function name. Fixes#8342
This just compares two longs as strings on the go.
We can simply
1. ignore leading zeroes - they have no influence on the value
2. compare the digits char-by-char
3. keep the comparison for the first differing digit
4. if one number is longer than the other, that is larger
5. if the numbers have the same length, the one larger in the first
differing digit is larger
This makes this comparison quite a bit faster, which makes globs in
directories with numbered files up to 20% faster.
Note that, for historical reasons, this still ignores whitespace right
after the numbers!
Mac OS 10.9 does not have the fstatat function which fish started
calling in commit 71a0d839a7. Let's end support for 10.9, which was
released in 2013.
Suggest files to "man -l", but only if the "-l" option is supported
(so not on BSD). Technically we should accept multiple files but this
seems good enough.
Also suggest files when the token-at-cursor contains a slash, because
man will treat arguments as file paths if they contain a /.
1ab81ab90d removed one usage of iswdigit()
but there are others; more importantly, the knowledge that iswdigit() is
slow isn't preserved anywhere apart from the git history, so there's
nothing to prevent its use from creeping back into the codebase.
Another alternative is to blacklist iswdigit() (shadow it with a
function of the same name that throws a static_assert) but if we're
going to shadow it anyway, might as well make it useful.
git-status --porcelain prints status letter T when a file changed type
between either regular file, symlink or submodule. It can occur in
exactly the same cases as M (modified), so extend the fix for #8311
accordingly.
For submodules, our completions are probably not always correct,
hopefully those cases are rare.
- 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.
