We have moved from saying "committing the working copy" towards saying
"snapshotting the working copy". More importantly, the option also
means that we don't update the working copy at the end. I went with
the `--ignore-working-copy` name suggested by Ilya. I also updated the
documentation of the option.
Even though the template syntax is experimental, panicking parser makes
it difficult to write tests. So let's add minimal error handling. The error
types are basically copied from the revset module.
I made write_commit_summary() fall back to the default template if user
template had syntax error. It should be better than reporting parse error
after e.g. "jj abandon" finished successfully.
Accept an --include-defaults arg to enable including those.
Listing a nonexistent name is no longer an error, but does output a
warning to stderr when no config entries match to explain why there's no
other output.
I have no idea whether or not any template expressions are intentionally
allowed as a label, but it makes sense to write something like
'label("phase-" phase, ...)' (if we had a phase keyword.) So I decided to
add .into_plain_text() instead of stricter .try_into_string().
This allows us to use "if(description,)" to test empty description. And
I think this change is unavoidable if we want to add support for commit
template.
I think this is the same bug as reported in #922, just simplified a
bit further. The branches in the repo actually look good after the
`undo` operation, but the reverted `master` branch doesn't get
exported to the git repo even though our recorded `refs/heads/master`
in the repo was moved back. Then the next automatic import on `log`
notices that the `master` branch in the git repo still points to the
new commit, and that commit becomes visible again.
Fix a bug where `jj git push` would print "No current branch." when
there is a current branch but it is unchanged. We were conflating the
two because we print the message when no updates were performed, instead
of only when no branches were found.
Add a new git.auto-local-branch config option. When set to false, a
remote-tracking branch imported from Git will not automatically create a
local branch target. This is implemented by a new GitSettings struct
that passes Git-related settings from UserSettings.
This behavior is particularly useful in a co-located jj and Git repo,
because a Git remote might have branches that are not of everyday
interest to the user, so it does not make sense to export them as local
branches in Git. E.g. https://github.com/gitster/git, the maintainer's
fork of Git, has 379 branches, most of which are topic branches kept
around for historical reasons, and Git developers wouldn't be expected
to have local branches for each remote-tracking branch.
Suppose "template" is a sequence of "term"s, it makes more sense to handle
an empty sequence there. It might be even better to disallow empty template
other than the top-level one.
A "list" is a sequence of more than one "term" nodes, so it shouldn't contain
a single parenthesized node.
Also, a parenthesized "term" rule wasn't handled.
I think of it more as style than a format, so using `style` in the
config key makes sense to me.
I didn't bother making upgrades easy by supporting the old name since
this was just released and only a few developers probably have it set.
The name of the [alias] section is inconsistent with other
table-valued sections ([revset-aliases], [colors], [merge-tools]), so
let's rename it. For comparison, `Cargo.toml` also uses plural names
(e.g. `[dependencies]`).
I don't think need to write non-UTF8 bytes to our config files. If we
ever do (maybe to test that we give the user a reasonable error
message), we add a custom function for that.
Fixes#787
If `jj squash` is run on an empty commit, it fails with "Error: No changes selected"
With this change such squash command will behave like `jj abandon`.
I would expect `set_up_fake_[diff_]editor()` to create an empty script
but it turns out they didn't even create the files. That means that
the caller needs to write an empty script to them if they want the
fake editors to not do anything. Let's instead write the empty
scripts, for a less surprising behavior.
I've preferred "working-copy commit" over "checkout" for a while
because I think it's clearer, but there were lots of places still
using "checkout". I've left "checkout" in places where it refers to
the action of updating the working copy or the working-copy commit.
This should fix the panic in the case reported in #1107. It's a bit
hard to reproduce because we normally notice the missing commit when
we snapshot the working copy, but it's possible to reproduce it using
`--no-commit-working-copy`.
I suspect the added test is too brittle because it checks the exact
error message. On the other hand, it might be useful to have one test
case like this so we catch accidental changes in the format.
This is ugly, but we need a special case because root_change_id and
root_commit_id aren't equal but share the same prefix bytes. In practice,
no one would care for the shortest root id prefix, but we'll need to deal
with a similar problem when migrating prefix id resolution to repo layer.
I think the intent of '- 1' here is the separator length, which was
originally ':'. Alternatively, we can ensure that prefix + remainder is
always 12 chars.
