I think it's a little easier to follow if we don't update the stats in
the large callback. It also reduces the risk of forgetting to update
the stats in some case (like in the exec-bit-optimization case I just
removed).
When updating the working copy from one tree to another, if only the
executable bit has changed between the two trees, we set the
executable bit on the file without touching its contents. The
optimization probably gets used quite rarely. Maybe it's even so
rarely that it's a pessimization overall. Perhaps its value lies more
in that we avoid updating the file's mtime unnecessarily. Either way,
I'm about to change this code to use `Merge<Option<TreeValue>>` and
that will make this block more complex. I don't think it's worth the
complexity even it provides some small benefit sometimes.
This allows negative numbers, which also means functions which took numbers can now take negative numbers
Luckily, they all already handled this exactly as expected.
Many of the `TreeBuilder` users have an `Option<TreeValue>` and call
either `set()` or `remove()` or the builder depending on whether the
value is present. Let's centralize this logic in a new
`TreeBuilder::set_or_remove()`.
One of the error types that I later created embedded `BackendError`, but `clippy` complained that the size of the type was too large. This helps address that.
The way `jj git push` without arguments chooses branches pointing to
either `@` or `@-` is unusual and difficult to explain. Now that we
have `-r`, we could instead default it to `-r '@-::@'`. However, I
think it seems likely that users will want to push all local branches
leading up to `@` from the closest remote branch. That's typically
what I want. This patch changes the default to do that.
If there are branches in the revset that don't need to be pushed
because they already match the destination, we currently just print
`Nothing changed.` It seems consistent with that to also treat it as
success if there are no branches in the specified set to start
with. This patch makes the command print a warning in that case
instead.
The VS Code "Better TOML" plugin (which I think most of our VS Code developers use?) doesn't support the `x.y = z` syntax at the top level, even though it's valid TOML.
This is also useful if we ever want to add additional properties in different sub-crates (although unlikely for the near future).
`vimtabdiff` has a few potential advantages:
- It can be much more convenient for diffs with few files
- It can be easier to set up for some people (it is a Python script rather
than a Vim plugin).
- The author accepts patches, and I hope to make it support 3-pane diff.
The pros and cons are also described in the linked Gist.
When the main `TreeState::snapshot()` thread doesn't receive any
updated tree entries over the channel, it correctly doesn't write a
new tree. However, it also doesn't write the working copy state file
(`.jj/working_copy/tree_state`). This resulted in performance
regression in 3f97a6da78. From that commit, repeated snapshotting
would have to re-read all files from disk because it didn't remember
the updated mtime from the previous time.
This patch fixes the bug by also writing the file if there were any
new file states.
This doesn't seem to make any difference right now, but it will if we
write the state file when there are mtime-only changes, which we
currently don't do.
`revset::parse()` already has a `RevsetWorkspaceContext` argument, so
I think it makes sense to put that and the other context arguments
into a larger `RevsetParseContext` object.
We resolve file paths into repo-relative paths while parsing the
revset expression, so I think it's consistent to also resolve which
workspace "@" refers to while parsing it. That means we won't need the
workspace context both while parsing and while resolving symbols.
In order to break things like `author("martinvonz@")` (thanks to @yuja
for catching this), I also changed the parsing of working-copy
expressions so they are not allowed to be
quoted. `author(martinvonz@)` will therefore be an error now. That
seems like a small improvement anyway, since we have recently talked
about making `root` and `[workspace]@` not parsed as other symbols.
Custom binaries will often want to provide e.g. additional command
aliases, additional revset aliases, custom colors, etc. This adds a
mechanism for them to do that.
Per discussion in #2107, I believe "exact" is preferred.
We can also change the default to exact match, but it doesn't always make
sense. Exact match would be useful for branches(), but not for description().
We could define default per predicate function, but I'm pretty sure I cannot
remember which one is which.
git-branchless calls it a substring, so let's do the same.
FWIW, I copied literal:_ from Mercurial, but it's exact:_ in git-branchless.
I have no idea which one is preferred. Since this feature isn't released, we
can freely change it if exact:_ makes more sense.

This commit replaces the functions `UserSettings::user_name_placeholder()`` and
`UserSettings::user_email_placeholder()` with `const` `&str`s to emphasize that
the placeholder strings must not be changed to support commits without
names or email addresses made before this change.
