For a new user, it is not clear how to view the full commit
message/description of a change with `jj log`.
This fix this, add a new template alias
`builtin_log_compact_full_description` to display the commit like
`builtin_log_compact` does but with a full description.
The user can set it to true on the config like this:
```
templates.log = builtin_log_compact_full_description
```
Fixes: #3688
When `format_short_signature(signature)` is set to `signature.name()` the author names are not yellow like other signature types (eg email and username). When the commit signatures have no colors, they blend in making it hard to distinguish between signatures and commit messages.
If just `name` were set to `yellow`, just like email and username, it affects the colorization of branch names making them also yellow despite them being designated as magenta. Setting `author` and `committer` to `yellow` is specific enough to allow branches to keep their colors while still coloring signature names. This is known to affect signatures in both 'log' and 'show'.
As discussed in #2900, the milliseconds are rarely useful, and it can
be confusing with different timezones because it makes harder to
compare timestamps.
I added an environment variable to control the timestamp in a
cross-platform way. I didn't document because it exists only for tests
(like `JJ_RANDOMNESS_SEED`).
Closes#2900
this greatly speeds up the time to run all tests, at the cost of slightly larger recompile times for individual tests.
this unfortunately adds the requirement that all tests are listed in `runner.rs` for the crate.
to avoid forgetting, i've added a new test that ensures the directory is in sync with the file.
## benchmarks
before this change, recompiling all tests took 32-50 seconds and running a single test took 3.5 seconds:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test test_working_copy'
Time (mean ± σ): 3.543 s ± 0.168 s [User: 2.597 s, System: 1.262 s]
Range (min … max): 3.400 s … 3.847 s 10 runs
```
after this change, recompiling all tests take 4 seconds:
```
; hyperfine 'touch lib/src/lib.rs ; cargo t --test runner --no-run'
Time (mean ± σ): 4.055 s ± 0.123 s [User: 3.591 s, System: 1.593 s]
Range (min … max): 3.804 s … 4.159 s 10 runs
```
and running a single test takes about the same:
```
; hyperfine 'touch lib/src/lib.rs && cargo t --test runner -- test_working_copy'
Time (mean ± σ): 4.129 s ± 0.120 s [User: 3.636 s, System: 1.593 s]
Range (min … max): 3.933 s … 4.346 s 10 runs
```
about 1.4 seconds of that is the time for the runner, of which .4 is the time for the linker. so
there may be room for further improving the times.
