This also allows scoped feature tests that makes testing feature flags thread-safe.
As in you can guarantee that the test actually has the correct feature flag
value, regardless of which other tests are running in parallell.
This also cleans up and removes unnecessary usage of FFI-oriented `feature_metadata_t`,
which is only used from Rust code after `builtins/status` was ported.
This ran two `test`s a `count` and one `echo`, which is a bit wasteful.
So instead, for the common case where you pass one argument, this will
run one `set -q`.
This can save off ~160 microseconds for each ordinary `cd`, which
speeds it up by a factor of ~2 (so 1000 runs of cd might take 260ms
instead of 550ms).
Ideally the cd function would just be incorporated into the builtin,
but that's a bigger change.
Note this is slightly incomplete - the FD is not moved into the parser, and so
will be freed at the end of each directory change. The FD saved in the parser is
never actually used in existing code, so this doesn't break anything, but will
need to be corrected once the parser is ported.
This shaves about 9 seconds off of the runtime, and makes the test
deterministic.
We do not touch the test_convert test because there is a known failure and we
need to track it down before making it deterministic.
Get some stuff out of the common module, which is growing large.
Also migrate the tests into "native" Rust tests so they will run in parallel.
We have to use an explicit setlocale() call to get a multibyte locale, for the
"crazy" tests.
Prior to this commit, FLOG used the ffi bridge to get the output fd. Invert
this: have fish set the output fd within main. This allows FLOG to be used in
pure Rust tests.
After accidentally running a command that includes a pasted password, I want
to delete command from history. Today we need to recall or type (part of)
that command and type "history delete". Let's maybe add a shortcut to do
this from the history pager.
The current shortcut is Shift+Delete. I don't think that's very discoverable,
maybe we should use Delete instead (but only if the cursor is at the end of
the commandline, otherwise delete a char).
Closes#9454
The tentative binding for the upcoming "history-pager-delete" is
bind -k sdc history-pager-delete or backward-delete-char
When Shift+Delete is pressed while the history pager is active,
"history-pager-delete" succeeds. In this case, the "or" needs to kick the
"backward-delete-char" out of the input queue.
After doing so, it continues reading, but interprets the input as
single-char binding. This breaks when the next key emits a multi-char sequence,
like the arrow keys.
Fix this by reading a full sequence, which means we need to run "read_char()"
instead of "read_ch()" (confusing, right?).
I'm still working on writing a test. Somehow this only reproduces in the
history pager where Shift+Delete followed by down arrow emits "[B" (since
we swallowed the leading escape char). Confusingly, it doesn't do that in
the commandline or the completion search field.
Two small fixes:
1. ParsedSourceRef, if present, should not be None; express that in the type.
2. ParsedSourceRef is intended to be shareable across threads; make it so.
Use as_wstr() instead of from_ffi() in a few places to avoid an allocation,
and make job_control_t work in &wstr instead of &str to reduce complexity at
the call sites.
- Using an option makes it much clearer that the check for empty args is
redundant.
- Also prefer implementing TryFrom only for &str, to not hide the string
conversion and allocation happening.
