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.
The tmux-prompt test would sometimes fail because the first call was:
isolated-tmux capture-pane -p
this would run a capture-pane which would race with starting fish
itself; occasionally the pane would be empty since fish has not yet
drawn a prompt. Add a loop to give fish time to draw the prompt.
On macOS, the tests would often fail because calls to `pkill` would "leak"
across tests: kill processes run by other tests. This is because on macOS,
the -P argument to pkill must come before the process name. On Linux it
doesn't matter.
This improves test reliability on Mac.
For littlecheck/pexpect this just unconditionally enables color.
I have no idea what happens if you run cmake outside of a terminal
, but the worst that can happen is that *errors* have color
escapes in them.
If someone figures out how to get cmake to tell us if it's running in
a terminal, we can add a check.
Tmux has support for wrapping arbitrary escape sequences inside
```
\ePtmux;\e%s\e\\
```
Since this ends like the screen title escape, we just reuse that.
Characteristically, this is basically undocumented, but we already use
it in e.g. fish_vi_cursor.
This used the *logical* $PWD, but realpath would operate on the
physical $PWD if given ".", even with -s. This makes this test fail if the $PWD is
logically different from physical.
This means instead of printing at least two lines per successful test,
we overwrite one line again and again with the current status, and
for *failed* (i.e interesting) tests we print the output.
Makes test failures much more visible.
This was long overdue since the setup logic is much more complex than
the actual tests.
tmux-prompt.fish had extra logic to protect against XDG_CONFIG_HOME
with leading double double-dot. I believe this is no longer necessary
with the new test driver.
We still use our own temp dir because we want to be able to run this
independently of the test driver, This can be useful for debugging
tests. For example we can insert a "$tmux attach" command in a test,
and then run
build/fish -C 'source tests/test_functions/isolated-tmux.fish' tests/checks/tmux-bind.fish
This allows to inspect the state of the test and debug interactively.
Attaching to the terminal doesn't work when running inside littlecheck
because littlecheck consumes our output and doesn't give us a terminal.
(Maybe there's an easy way to fix that?)
On request of a team member, this patches `basic.fish` to no longer
depend on being invoked by the test driver and started up in a $PWD that
points to a clean temporary directory.
This was requested by a team member who would like for some tests to
remain invokable (in thier own $HOME) directly via littlecheck without
relying on the test driver to prep the environment.
A comment explaining the rationale is also added so this doesn't get
passed down as folklore "you need to include this for tests to run" even
though no one understands why.
