780bac671f did not actually successfully
compile on any platforms, leading to -latomic always being added
(including on platforms it does not exist on).
Work on #5865.
Do this only when splitting on IFS characters which usually contains
whitespace characters --- read --delimiter is unchanged; it still
consumes no more than one delimiter per variable. This seems better,
because it allows arbitrary delimiters in the last field.
Fixes#6406
user_supplied was used to distinguish IO redirections which were
explicit, vs those that came about through "transmogrphication." But
transmogrification is no more. Remove the flag.
"-C" is short for "--case-sensitive", which is entirely okay with "--delete".
The one that isn't okay is "-X", which is short for "--Clear".

This patch keeps the existing `make` shims via `GNUmakefile` and
`BSDmakefile` but also resolves the issue reported in #6264 with
CMake-generated `Makefile` overwriting the extant `Makefile` causing the
source directory to become dirty once again.
Closes#6264
This prefixes files beginning with `-` with a `./` when generating
completions *in fish code*. Standard completions for directory listings
generated by the C++ directory traversal code are not afected by this
patch.
Most fish completions defer to `__fish_complete_suffix` to generate the
file/directory completions, these *will* be corrected.
As of GCC 7.4 (at least under macOS 10.10), the previous workaround of
casting a must-use result to `(void)` to avoid warnings about unused
code no longer works.
This workaround is uglier but it quiets these warnings.
The C++ spec (as of C++17/n4713) does not specify the sign of `wchar_t`,
saying only (in section 6.7.1: Fundamental Types)
> Type wchar_t shall have the same size, signedness, and alignment
> requirements (6.6.5) as one of the other integral types, called its
> underlying type.
On most *nix platforms on AMD64 architecture, `wchar_t` is a signed type
and can be compared with `int32_t` without incident, but on at least
some platforms (tested: clang under FreeBSD 12.1 on AARCH64), `wchar_t`
appears to be unsigned leading to sign comparison warnings:
```
../src/widecharwidth/widechar_width.h:512:48: warning: comparison of
integers of different signs: 'const wchar_t' and 'int32_t' (aka 'int')
[-Wsign-compare]
return where != std::end(arr) && where->lo <= c;
```
This patch forces the use of wchar_t for the range start/end values in
`widechar_range` and the associated comparison values.
Previously, if the user control-C'd out of a process, we would set a
bogus exit status in the process, but it was difficult to observe this
because we would be cancelling anyways. But set it properly.
If a Control-C is received during expanding a command substitution, we
may execute the job anyways, because we do not check for cancellation
after the expansion. Ensure that does not happen.
This should fix sporadic test failures in the cancellation unit test.
parser_t::eval indicates whether there was a parse error. It can be
easily confused with the status of the execution. Use a real type to
make it more clear.
$GIT_DIR is interpreted by git as an environment variable, pointing at the
.git directory. If git_version_gen.sh is run in an environment with an
exported GIT_DIR, it will re-export GIT_DIR to point at the fish source
directory. This will cause git operations to fail.
This could be reproduced as building fish as part of an interactive rebase
'exec' command. git_version_gen.sh would always fail!
Looking up a variable by a string literal implicitly constructs a wcstring.
By avoiding that, we get a noticeable reduction of temporary allocations.
$ HOME=. heaptrack ./fish -c true
heaptrack stats: # baseline
allocations: 7635
leaked allocations: 3277
temporary allocations: 602
heaptrack stats: # new
allocations: 7565
leaked allocations: 3267
temporary allocations: 530
Closes#6435.
close_fds=True is actually the default in Python 2.7 and 3.2, but not in
ancient (but still in production in Red Hat Enterprise Linux 6) Python
2.6. Enable it there as well.
From the `git-switch` documentation:
If <branch> is not found but there does exist a tracking branch in
exactly one remote (call it <remote>) with a matching name, treat as
equivalent to
$ git switch -c <branch> --track <remote>/<branch>
