This makes it so we treat backspaces as width -1, but never go below a
0 total width when talking about *lines*, like in screen or string
length --visible.
Fixes#8277.
* Hide whatis database building from the user
It's really an internal detail, but shows up in prompts that display how many
background jobs are running.
By disowning it keeps running but won't show up in `jobs` or get killed if the user
exits the shell.
* Update __fish_apropos.fish
OpenBSD has a posix_spawn implementation which fails to return ENOEXEC
on a shebangless script, causing us to fail the shebangless tests.
Disable posix_spawn on OpenBSD.
OpenBSD's mmap is famously unsychronized with file IO. In theory fsync
and msync can be used to synchronize but I was unable to get it to work.
Just don't use mmap for history on OpenBSD. This fixes the history merge
tests.
When getting the hostname to construct the legacy uvar path, if the
hostname is empty, we will create a path pointing at a directory. On
BSDs this path can be successfully open'd and we will produce errors
about invalid uvar files.
Splitting fish into multiple packages was what the downstream Debian
packaging does, but it provides minimal benefit to end-users installing
from the fish repositories and in some cases made it harder. The only
benefit was a slightly reduced size on disk for download repositories.
Closes#7845.
Reverts 45ae726d4f and solves #3053
through a Conflict with fish-common.
The less -F / --quit-if-one-screen option is buggy before v530. To work
around this, pass --no-init less versions older than 530.
The --no-init option was previously passed; it was removed in d15a51897d
for mouse support. Unfortunately it looks like we can't have mouse
support and --quit-if-one-screen on macOS shipped less (version 487).
It's worth fixing this because otherwise history and help is just not
printed on stock macOS.
Relevant is https://unix.stackexchange.com/questions/107315/less-quit-if-one-screen-without-no-initFixes#8157.
The "linear" wildcard_match actually contained a bug that compared two
strings on every iteration, causing this to be much slower than
necessary. Fix this.
To broadcast a uvar change on Linux, we write to a named pipe, wait a bit,
and then read it back. While the pipe is readable, fish will enter a "polling
mode" where it will check for uvar changes every N msec, until the pipe is no
longer readable. If the pipe stays readable for too long (5 seconds), fish
will try to drain it; this may happen if broadcasting instance of fish is
killed before it can read back its data.
In #8209 we have a case where fish is launched in the background to set a
uvar, and then immediately exits, leaving data on the pipe. This means that
we are perpetually in a polling mode until we hit that timeout. Reduce the
timeout to 1 second and the polling interval to 10 msec.
This improves #8209; it doesn't fix it fully but I think it's the best we can
do absent some other IPC mechanism.
Now that we removed EROTTEN which had the same error code as EPERM,
we can give a less confusing error in case a user has not allowed
their terminal access to a directory.
See #8264
When cd is passed a broken symlink, this changes the error message from
"no such directory" to "broken symbolic link". This scenario probably
won't happen very often since completion won't suggest broken symlinks
but it can't hurt to give a good error.
Fish used to do this until 7ac5932. This logic used to be in
path_get_cdpath, however, that is only used for highlighting, so we
don't need error messages there. Changing cd is enough.
Reword from "rotten" to "broken" since that's what file(1) uses.
Clean-up leftovers from old "rotten" code (nomen est omen).
See #8264
CMake 3.5 (shipped in Ubuntu Xenial) doesn't generate the test target
with appropriate dependencies. Build them in dh_auto_build; it's too
hard to convince any of the other steps to do it.
See #7851.
Commit c3374ffd0 ("Use read --tokenize instead of eval for $BROWSER &
$EDITOR") converted uses of "eval" for environment variables to use the
safer "read -at", which performs word splitting but no other expansion.
funced contained a leftover instance of "eval". Remove it in favor
of using the editor command that was already word-split.
This means that we don't accidentally evaluate the file name.
(Also "set -gx EDITOR=~/my-editor" won't work anymore because the ~
is not expanded anymore but no one has complained about that behavior
in edit_command_buffer.)
Fixes#8289
*Problem:*
edit_command_buffer uses `cat` to return the modified content.
If a person has an alias for `cat` to a different command such `bat`** the editing will not be useful anymore since bat decorates the text with frames, line counts, etc
*Solution*
Appending command to cat, fish will ignore the alias and execute the real command according to this https://fishshell.com/docs/current/cmds/command.html
** https://github.com/sharkdp/bat
This currently changes builtin realpath with the "-s" option:
builtin realpath -s ///tmp
previously would print "///tmp", now it prints "/tmp".
The only thing "allow_leading_double_slashes" does is allow *two*
slashes.
This is important for `path match`, to be introduced in #8265.
This lets us run non-fish targets (such as `fish_tests`) under a clean
test environment without running into the fish-specific payload
configuration now carried out by `test_driver.sh` which expects a
`.fish` payload that it will run under a deterministically configured
instance of fish, running in an environment initialized by
`test_env.sh`.
This should fix the problem with in-tree builds leaving detritus behind
after a `make test` when `fish_tests` would be executed without
`test_driver.sh` - it is now executed under `test_env.sh` instead.
