Fixes some potentially unsafe uses of direct substitution into regex
expressions and also switches some completions to regex-based now that
there is a safe way of using it.
If fish detects that it was started with a pgrp of 0 (which appears to
oddly be the case when run under firejail), create new process group for
fish and give it control of the terminal.
This selectively reverts 55b3c45 in cases where an invalid pgrp is
detected. Note that this is known to cause problems in other cases, such
as #3805 and Microsoft/WSL#1653, although the former may have been
ameliorated or even addressed by the recent job control overhaul, so
that's why we are careful to only assign fish to its own pgroup if an
invalid pgroup was detected and not as the normal case.
This reverts commit 54050bd4c5.
Type job_list_t was changed from a list to a deque in
commit 54050bd4c5.
In process_clean_after_marking(), we remove jobs while iterating.
dequeues do not support that. Make it a list again.
This fixes the `~floam/` case, where the out_tail_idx pointer needs to
point to the "/", not the last letter.
The `~/` and `~floam` cases still work.
Unfortunately, I'm unsure of how to test this.
Fixes#5325.
In writing the completion script for openocd I found the need to
complete paths at the command-line as if they were relative to a
path other than the current $PWD. Given that `$PWD` is currently
global in fish (i.e. no side-effect free `cd` within a subshell)
this is probably good to have for other completions too.
This also fixes a bug in support for explicitly supplying the
description for completions via a `$argv` parameter, which prefixed
the description with `\t` (which is correct) except it did so in
the local scope within an `if` statement, meaning the changes never
had any effect and in the output the description was directly
concatenated to the completions, instead of separated by a tab.
Incorrectly assumed that pandoc uses XDG_CONFIG_HOME, it turns out the
path is hard-coded as $HOME/.pandoc unless explicitly otherwise
specified in the command-line.
Limit the fish_wcstod fast path to ASCII digits only, to fix the problem
observed in the discussion for a700acadfa
where LANG=de_DE.UTF-8 would cause `test` to interpret commas instead of
periods inside floating point values.
This merges a stack that removes the WAIT_BY_PROCESS and NESTED job flags.
Instead jobs are taught about their parents, and parents are interrogated to
determine whether they are fully constructed, and therefore whether it is
safe to call waitpid().
Now jobs are aware of their parent jobs, and can interrogate those jobs,
to determine if every job in the chain is fully constructed.
Remove flags and the static stacks that manipulated them.
The parent of a job is the parent pipeline that executed the function or
block corresponding to this job. This will help simplify
process_mark_finished_children().
Prior to this fix, cding into a symlink and then completing .. would complete
from the physical directory instead of the logical directory, which could not
actually be cd'd to. Teach cd completiond to use the logical directory.
