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.
Tests are now executed in a test-specific temporary directory, so test
output on failure should be reproducible/reusable as-is without needing
to have TMPDIR defined (as it only exists by default under macOS).
`test:foo` is not allowed by CMake ("reserved name") and `test/foo`
won't work since CMake doesn't allow targets to have a directory
separator in their name.
Instead of trying to assert that there are no zombies when the test
starts (which often fails) and to prevent conflating existing or
irrelevant zombies with the ones we are interested in checking for,
have `ps` also emit the parent process id and filter its output to
include only children of the current fish instance.
Aside from the fact that the shared state could cause problems, tests
were randomly assuming it would be created where that wasn't the case.
In particular, `redirect.fish` and `basic.fish` were failing on only
macOS because `../test/temp` didn't exist yet - it would be created by
other tests later.
The default matching logic for fish_tests was prefix based, so when we
were running `history` we were also running all history tests. This
causes the test to fail for an unknown reason.
Even though we are using CMake's ctest for testing, we still define our
own `make test` target rather than use its default for many reasons:
* CMake doesn't run tests in-proc or even add each tests as an
individual node in the ninja dependency tree, instead it just bundles
all tests into a target called `test` that always just shells out to
`ctest`, so there are no build-related benefits to not doing that
ourselves.
* CMake devs insist that it is appropriate for `make test` to never
depend on `make all`, i.e. running `make test` does not require any
of the binaries to be built before testing.
* The only way to have a test depend on a binary is to add a fake test
with a name like "build_fish" that executes CMake recursively to
build the `fish` target.
* It is not possible to set top-level CTest options/settings such as
CTEST_PARALLEL_LEVEL from within the CMake configuration file.
* Circling back to the point about individual tests not being actual
Makefile targets, CMake does not offer any way to execute a named
test via the `make`/`ninja`/whatever interface; the only way to
manually invoke test `foo` is to to manually run `ctest` and specify
a regex matching `foo` as an argument, e.g. `ctest -R ^foo$`... which
is really crazy.
With this patch, it is now possible to execute any single test by name,
by invoking the build directly, e.g. to run the `universal.fish` check:
`cmake --build build --target universal.fish` or
`ninja -C build universal.fish`. Unfortunately, this is not integrated
into the Makefile wrapper, so `make universal.fish` won't work (although
this can potentially be hacked around).
Instead of compiling `fish_tests.cpp` dynamically with weakly-linked
symbols and asking it to print the list of all available tests, we
use a magic string `#define`'d as a no-op to allow CMake to regex search
for matching test groups. This speeds up configuration somewhat (by not
compiling anything), but more importantly, it's much less brittle and
doesn't involve and linker dark magic.
There's of course still no getting around the fact that it's really ugly.
We have a *lot* of color sequences to try and tparm is slow (on the
whole, when you do this thousands of times).
So let's just check colors last, which makes everything else (which is
comparatively nothing) faster, while barely impacting
colors (benchmarking confirms no measurable difference).
Fixes#8253.
* Fix ls.fish: add -l option to GNU ls
* Sort alphabetically and remove --lcontext and --scontext (what are these?) on shared and GNU part.
* Revert --lcontext and --scontext options.
Unfortunately, we now need to know which .html file has which sections
to link to the correct one in help.fish.
So this script helps extract the sections from pre-built docs. It's
not supposed to be run at build time because
1. These change rarely.
2. We should link to the correct document even if the user doesn't
have the docs built.
And before anyone mentions it: This does *not* parse html with regex.
This "parses" the restricted subset of "class followed by href without
embedded quotes" that sphinx uses here in practice.
This should add all the sections that aren't linked internally,
including "identifiers".
(also give up on the line breaking because it makes it annoying to do
automatically)
Fixes#8245.
Fixes#8232.
Note that this needed to have expect_prompt used in the pexpect test -
we might want to add a "catchup" there so you can just ignore the
prompt counter for a bit and pick it back up later.
This was semi-automated with
```fish
for file in $argv
set -l varname (string replace -r '.*/(.*).html' '$1' -- $file | string escape --style=var)pages
set -l sections (string replace -rf '.*class="headerlink" href="#([^"]*)".*' '$1' <$file)
echo set -l $varname $sections
end
```
(where $argv contains the path to faq, fish_for_bash_users,
interactive, language and tutorial.html)
Building help.fish at compile time would work, but only for users who
build the docs.
* Remove safe_strerror, safe_perror and safe_append
This no longer works on new glibcs because they removed sys_errlist.
So just hardcode the relevant errno messages (and phrase them better).
Fixes#4183.
