Since we abuse TOML table syntax to define function aliases, an identical
function alias can be found more than once in the merged config. The merged
config doesn't preserve the definition order, so we need to load aliases
table per layer.
`jj sparse` is a bit different from other commands in that its `jj
sparse --list` is practically a separate command. Let's make it an
actual subcommand for consistency, and so we can more cleanly add
additional flags for `jj sparse list` in the future. I moved all the
other arguments to `jj sparse set`. I'm not sure if `jj sparse set
--reset` would have been better as `jj sparse reset`, but it is
technically just updating the sparse patterns just like the other
arguments (`--clear`, `--add` , `--remove`).
It's easier to follow the test if we try to resolve commits from the
`jj log` output just above. That's what we did until I changed it away
from that without thinking in fcda05c69b.
When I added `revsets.short-prefixes` in 20ef171d7a, I didn't notice
that I made the test of commit prefixes among hidden commits
ineffective because. This restores that by disabling short prefixes in
the test.
This bug concerns the way `import_refs` that gets called by `fetch` computes
the heads that should be visible after the import.
Previously, the list of such heads was computed *before* local branches were
updated based on changes to the remote branches. So, commits that should have
been abandoned based on this update of the local branches weren't properly
abandoned.
Now, `import_refs` tracks the heads that need to be visible because of some ref
in a mapping keyed by the ref. If the ref moves or is deleted, the
corresponding heads are updated.
Fixes#864
Before this, it was difficult to run an integration test after adding any
directives from printf-style debugging to jj (e.g. `err!`, `eprintln!`,
`println!`), since `jj_cmd_success` fails if `jj` to output anything to stderr
while `jj_cmd_failure` fails if stdout is not empty.
This adds a `TestEnvironment::debug_allow_stderr` variable that lifts this
restriction for `jj_cmd_success` and makes it output anything `jj` output to
stderr instead. You can set it directly or by running the test with the
`DEBUG_ALLOW_STDERR` environment variable set. You can then add `err!`
anywhere.
You do need to run the test in a somewhat special way, as described in the
docstring.
This adds a config called `revsets.short-prefixes`, which lets the
user specify a revset in which to disambiguate otherwise ambiguous
change/commit ids. It defaults to the value of `revsets.log`.
I made it so you can disable the feature by setting
`revsets.short-prefixes = ""`. I don't like that the default value
(using `revsets.log`) cannot be configured explicitly by the
user. That will be addressed if we decide to merge the `[revsets]` and
`[revset-aliases]` sections some day.
I plan to add `revsets.short-prefixes` and `revsets.immutable` soon,
and I think `[revsets]` seems like reasonable place to put them. It
seems consistent with our `[templates]` section. However, it also
suffers from the same problem as that section, which is that the
difference between `[templates]` and `[template-aliases]` is not
clear. We can decide about about templates and revsets later.
Before, HEAD@git was at change `e1f4` mentioned in the test. So, as long as we
consider the behavior added in 20eb9ec to be correct, that change should NOT
have been abandoned after the fetch, in spite of what the comment in the test
says. In other words, the test did NOT demonstrate a bug before this commit.
Now, the test properly demonstrates the bug.
Cc #864
The current behavior was introduced by 20eb9ecec1 "git: don't abandon
HEAD commit when it loses a branch." While the change made HEAD mutation
behavior more consistent with a plain ref operation, HEAD can also move on
checkout, and checkout shouldn't be considered a history rewriting operation.
I'm not saying the new behavior is always correct, but I think it's safer
than losing old HEAD branch. I also think this change will help if we want
to extract HEAD management function from git::import_refs().
Fixes#1042.
On "jj checkout", description of the working-copy commit is empty, and the
working-copy parent provides more information. It might be a bit verbose to
print parent summary on every history rewriting, but I think that's okay.
If "jj op undo" doesn't roll back git refs (#1541), test_git_import_undo()
would get weird state. I think these tests are easier to follow than
test_git_fetch_undo() since no remote refs are involved.
"jj show" is basically a "log" command with different defaults. We'll need
to consider this kind of stuff if we want to introduce namespace to templates.
I think we should test actually performing the push when possible. I
think I initially used `--dry-run` because I thought it wasn't
possible to do local pushes with libgit2.
This is a convenience optimization to improve the default user
experience, since `jj log` is a frequently run command. Accessing the
help information explicitly still follows normal CLI conventions, and
instructions are displayed appropriately if the user happens to make a
mistake. Discoverability should not be adversely harmed.
Note that this behavior mirrors what Sapling does [2], where `sl` will
display the smartlog by default.

I wasn't quite happy with `jj support` but I couldn't think of
anything better when I moved the commands from `jj debug` in
e2b4d7058d. Thanks to @ilyagr for suggesting `jj util`.
This makes it clear what should be resolved at resolve_symbols(). Symbol
is a bit special while parsing function arguments, but it's no different
than the other unresolved references at expression level.
This changes the version number reported by `jj version` from "0.7.0"
to something like
"0.7.0-24a512683bc921699575b6a953624b05c068d544a". The hash is added
if running in a jj repo or a git repo.
The `heads()` revset function with one argument is the counterpart to
`roots()`. Without arguments, it returns the visible heads in the
repo, i.e. `heads(all())`. The two use cases are quite different, and
I think it would be good to clarify that the no-arg form returns the
visible heads, so let's split that out to a new `visible_heads()`
function.
The impact of not having configured one's name and email is not apparent from the warning message. Under the Toulmin model:
- Claim (implicit): You should configure your name and email.
- Grounds: Your name and email are not currently configured.
- Warrant (currently missing): Configuring your name and email will let you do...
This serves the role of limit() in Mercurial. Since revsets in JJ is
(conceptually) an unordered set, a "limit" predicate should define its
ordering criteria. That's why the added predicate is named as "latest".
Closes#1110
I think requests to reset the author came up twice in the last week,
so let's just add support for it. I copied git's behavior of resetting
the name, email, and timestamp. The flag name is also from git.
