This reverts commit 1cb8b2a87b.
argv[0] has the full path in it for a user when he executes it
out of $PATH. This is really annoying in the title which uses $_.
Also check if that is actually defined, not the cur_term proxy.
In #5371, we figured out that there are terminfo entries without this
capability, so this would do a NULL-dereference.
OCLINT was ignoring this, but we can just not do the bad thing.
Declare argc and argv const. These are in the stack, they can
be modified, but we won't.
Fix a typo
... rather than hard code it to "fish". This affects
what is found in $_ and improves the errors:
For example, if fish was ran with ./fish, instead of
something like:
fish: Expected 3 surprises, only got 2 surprises
we'll see:
./fish: Expected 3 surprises, only got 2 surprises
like most other shell utilities. It's just a tiny bit
of detail that can avoid confusion.
This broke fishtape, which did
somestuff | fish -c "source"
Because `source` didn't have a redirection, it refused to read from
stdin.
So, to keep the common issue of `source (command that does not print)`
from seeminly stopping fish, we instead actually check if stdin is a terminal.
This was causing problems if "fish" wasn't in exec_path, like
if the binary had been renamed.
I also noticed that even with 'fish' not renamed, only paths.data
was made relative to my source tree. paths.sysconf, paths.doc, and
paths.bin were all relative to /usr/local.
This had a bunch of "do_{backward,forward}" movements that differed
only in one argument.
Just keep them together, so it's less code, and less needs to be
changed.
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
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.
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.
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.
