We const cast these, so they aren't actually const,
and const doesn't actually help with optimization or anything (because const_cast exists),
so I would rather remove this, because const_cast gives me both the heebies and the jeebies.
When regenerating documentation with Sphinx, there's a warning issued about CHANGELOG.rst:
```
../CHANGELOG.rst:33: WARNING: Document or section may not begin with a transition.
```
This is almost identical to the fix in commit 84a89f5195.
I believe they are both equivalent for our particular purpose, since we
only care about enforcing the size fish sees.
`resize-window` was only introduced in tmux 2.9, which isn't available
at least on Ubuntu 18.04 LTS (currently using tmux 2.6) and probably
many others.
(Clever idea to use tmux here!)
When fish performs syntax highlighting, it attempts to determine which
arguments are valid paths and underline them. Skip paths whose length
exceeds PATH_MAX. This is an optimization: such strings are almost
certainly not valid paths and checking them may be expensive.
Relevant is #7837
Previously wbasename and wdirname wrapped the system-provided basename
and dirname. But these have thread-safety issues and some surprising
error conditions on Mac. Just reimplement these per the OpenGroup spec.
In particular these no longer trigger a null-dereference if the input
exceeds PATH_MAX.
Add some tests too.
This fixes#7837
Previously fish attempted to block all signals on background threads, so
that they would be delivered to the main thread. But on Mac, SIGSEGV
and probably some others just get silently dropped, leading to potential
infinite loops instead of crashing. So stop blocking these signals.
With this change the null-deref in #7837 will properly crash instead of
spinning.
Previously, both fish.pc and libfish had generating the
FISH-BUILD-VERSION-FILE attached as a command. In principle they could
both try to run the command simultaneously and now CMake complains about
this with the Xcode generator.
Switch to having fish.pc depend on the CHECK-FISH-BUILD-VERSION-FILE as a
target instead of a command. This allows it to participate in dependency
resolution and CMake will succeed again.
Fixes#7838
`streams.out.push_back` for fd_streams_t writes to the
fd *immediately*. We might want to introduce a general buffering
strategy, but in this case writing it in one go is the simplest and
seems acceptable - we already have constrained the argument size, so
just pushing it out should work well enough.
See #7836
013a563ed0 made it so we only try to
adjust terminal modes if we are in the terminal pgroup, but that's not
enough.
Fish starts background jobs in events inside its own pgroup, so
function on-foo --on-event foo
fish -c 'sleep 3' &
end
would have the backgrounded fish try to fiddle with the terminal and
succeed.
Instead, only fiddle with the terminal if we're interactive (this
should probably be extended to other bits, but this is the particular
problematic part)
Fixes#7842.
Consider
$ complete -c foo -a 'aab aaB' -f
$ foo A<TAB>
since 28d67c8 we would insert the common prefix AND show the pager.
Due to case-insensitive comparison, "b/B" was considered to be part
of the prefix. Since the prefix is added to each pager item [1]
we get wrong results. Fix this by removing the insensitive comparison
between completions - I don't think it was of much use anyway.
Commandline tokens are still matched case-insensitively, this is
just about completions.
Test this by running interactive fish inside tmux (pexpect's terminal
emulation not have enough capabilities). Also add tests for recent
interactive regressions #7526 and #7738.
Closes#3978
[1]: b38a23a would solve this differently by giving every pager item
its own prefix, but was reverted since it needs more fixes.
This should cover most cases - the user didn't install the docs and is
trying to view the man page via __fish_print_help, so we don't have a
way to show anything.
But `help thing` will fall back to the online version of the docs,
which should work if there's an internet connection.
See #7824.
Prior to this commit "builtin -h" would silently fail when no
documentation is installed. This happens when running fish without
installing it, or when the docs are not installed.
See #7824
After a fish installation is upgraded to 3.2.0, active shells could
throw an error attempting to load Git completions. It's just a
transient error but also easily avoidable by using the old style.
See #7822
Creating a file called "xfoo" could break the highlight tests because
we'd suddenly get a color with valid_path set to true.
So what we do is simply compare foreground/background and forced
underline, but only check for path validity if we're expecting a valid
path.
If we're not expecting a valid path, we don't fail whether it is there
or not.
This means that we can't check for a non-valid path, but we don't
currently do that anyway and we can just burn that bridge when we get
to it.
