I'm gonna add more tests to this and I don't want to touch the old stuff.
Notice that this needs to have the output of the complete_directories
test adjusted because this one now runs later.
That's something we should take into account in future.
Pursuant to 0be7903859, there still
remained one issue with the test when run from within a symlinked
directory after fish gained support for cding into symlinks.
This change should make the test function OK both when the tests are run
out of a PWD containing a symlink in its hierarchy and when run
otherwise.
The final test in `realpath.in` was based on the no-longer-valid
assumption that $PWD cannot be a symlink. Since the recent changes in
fish 3.0 to allow `cd`ing into "virtual" directories preserving symlinks
as-is, when `make test` was run from a path that contained a symlink
component, this test would fail the `pwd-resolved-to-itself` check.
As the test is not designed to initialize then cd into an absolute path
guaranteed to not be symbolic, so this final check is just wrong.
Illumos/OpenIndiana/SunOS/Solaris has an rm/rmdir that tries to
protect the user by not allowing them to delete $PWD.
Normally, this would be a good thing as deleting $PWD is a stupid
thing to do. Except in this case, we absolutely need to do that.
So instead we weasel around it by invoking an sh to cd out of the
directory to then invoke an `rmdir` to delete it. That should throw
off any attempts at protection (we could also have tried $PWD/. or
similar, but that's possibly still protected against).
This is the last failing test on
Illumos/OpenIndiana/SunOS/Solaris/afunnyquip, so:
Fixes#5472.
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
After implementing `builtin fish_realpath` it was noticed that it did
not behave like GNU `realpath` without options. Which is super annoying
since that was the whole point of implementing the command. Major
failure on my part since I wrote the unit tests to match the behavior of
the existing `wrealpath()` function that I simply exposed as a builtin
command. Rather than actually verifying it behaved in a manner
compatible with GNU realpath.
Also, while the decision to call the builtin `fish_realpath` seemed to
make sense at the time of the original commit further reflection has
shown that to be a silly, idiosyncratic, thing to have done. So rename
it to simply `realpath`.
Fixes 3400
