If the user is in a directory which has been unlinked, it is possible
for the path .. to not exist, relative to the working directory.
Always pass in the working directory (potentially virtual) to
path_get_cdpath; this ensures we check absolute paths and are immune
from issues if the working directory has been unlinked.
Also introduce a new function path_normalize_for_cd which normalizes the
"join point" of a path and a working directory. This allows us to 'cd' out of
a non-existent directory, but not cd into such a directory.
Fixes#5341
realpath() will return NULL and sets errno if it fails.
We asserted that realpath(".") does not fail. We also didn't really
check that it was successful. Made sure we'll get a perror telling
us about what went wrong if something like this happens again.
Updated tests and added test case
Fixes#5351
* Replace "env" with "expr" in the test manpage
I'm pretty sure `env` isn't capable of comparing numbers and the author meant `expr`.
* Update the docs regarding floats support in test
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.
