528ccb318e fileset: fall back to bare pattern/string if no operator-like character found
While I like strict parsing, it's not uncommon that we have to deal with file
names containing spaces, and doubly-quoted strings such as '"Foo Bar"' look
ugly. So, this patch adds an exception that accepts top-level bare strings.
This parsing rule is specific to command arguments, and won't be enabled when
loading fileset aliases.

9d7ed54f8e git_backend: add a README to conflicted commits
When you use e.g. `git switch` to check out a conflicted commit,
you're going to end up with the `.jjconflicts-*` directories in your
working copy. It's probably not obvious what those mean. This patch
adds a README file to the root tree to try to explain to users what's
going on and how to recover.

The authoritative information about conflicts is stored in the
`jj:trees` commit header. The contents of conflicted commits is only
used for preventing GC. We can therefore add contents to the tree
without much consequence.

a2c49abbbe Add short a -e alias for --edit to prev and next
I'm not sure if this was an intentional omission, but I think it would be
useful to have `-e` as a short flag for `--edit`. I don't usually edit commits,
but I do use `prev` and `next` with edit to navigate to a commit that I want to
squash. Often this is easier than typing `--from` and `--into` plus the change
IDs.

If people want to edit commits we shouldn't stand in their way.

e0c53bcfc0 Rewrite rebasing in jj split using transform_descendants()
This is following on the rewrite for `parallelize`.

- https://github.com/martinvonz/jj/pull/3521

Since rebase_descendants from rebase.rs is no longer used outside of that file,
it can be made private again.

Evan Mesterhazy
3f0e4de64a Allow advance_branches tests to be parameterized
In a future commit these tests will run with both `jj commit` and `jj new` since
both will have the same semantics for advancing the branch pointer.

Parameterizing the tests allows us to run both variants without duplicating the
test bodies. Since the commit IDs are different when `jj describe` + `jj new`
is used instead of `jj commit`, this commit also drops the commit IDs from the
test snapshots. This is fine because the commit IDs are not important for these
tests.

bbd9c7c7cb Implement advance-branches for jj commit
## Feature Description

If enabled in the user or repository settings, the local branches pointing to the
parents of the revision targeted by `jj commit` will be advanced to the newly
created commit. Support for `jj new` will be added in a future change.

This behavior can be enabled by default for all branches by setting
the following in the config.toml:

```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
```

Specific branches can also be disabled:
```
[experimental-advance-branches]
enabled-branches = ["glob:*"]
disabled-branches = ["main"]
```

Branches that match a disabled pattern will not be advanced, even if they also
match an enabled pattern.

This implements feature request #2338.

cce1b9f00a templates: use "+" instead of "#" to denote immutable node in ascii graph
Maybe it's personal preference, but the hash sign looks bigger compared to
the normal "o" nodes, and is slanted. This makes immutable commits stand out
too much. I think "+" is closer to the diamond character used in the unicode
template.

556747ad8c templater: cache immutable revset fn globally

user might add a few more to their text template, it seems reasonable to cache

8bb92fa6fa working_copy: allow load_working_copy() to return error
It's reasonable for a `WorkingCopy` implementation to want to return
an error. `LocalWorkingCopyFactory` doesn't because it loads all data
lazily. The VFS-based one at Google wants to be able to return an
error, however.

ddfdf5e357 cli: allow snapshot.max-new-file-size to be a raw u64
Previously, this command would work:

    jj --config-toml='snapshot.max-new-file-size="1"' st

And is equivalent to this:

    jj --config-toml='snapshot.max-new-file-size="1B"' st

But this would not work, despite looking like it should:

    jj --config-toml='snapshot.max-new-file-size=1' st

This is extremely confusing for users.

This config value is deserialized via serde; and while the `HumanByteSize`
struct allegedly implemented Serde's `visit_u64` method, it was not called by
the deserialize visitor. Strangely, adding an `visit_i64` method *did* work, but
then requires handling of overflow, etc. This is likely because TOML integers
are naturally specified in `i64`.

Instead, just don't bother with any of that; implement a `TryFrom<String>`
instance for `HumanByteSize` that uses `u64::from_str` to try parsing the string
immediately; *then* fall back to `parse_human_byte_size` if that doesn't work.
This not only fixes the behavior but, IMO, is much simpler to reason about; we
get our `Deserialize` instance for free from the `TryFrom` instance.

Finally, this adjusts the test for `max-new-file-size` to now use a raw integer
literal, to ensure it doesn't regress. (There are already in-crate tests for
parsing the human readable strings.)

3d267de53e Use CommitIteratorExt to replace .map(|c| c.id().clone())
This replaces `.map(|c| c.id().clone())` with `.ids().cloned()` to use nicer
syntax for getting `CommitId`s from an iterator of commits using the
`CommitIteratorExt` trait.

In one case we can actually call `.parent_ids()` directly. I also pluralized a
variable to make it clearer that it's a vec of IDs and not a single ID.

449fc423b8 parallelize: drop redundant "Nothing changed." case
The rewritten code is already a no-op when there's a single input. I
don't think the case is common enough to warrant having a special case
for performance reasons either. Also, by not having the special case,
`jj parallelize <immutable commit>` fails consistently with the
non-singleton case.

d6b41c18c9 parallelize: rewrite using transform_descendants()
`jj parallelize` was a good example of a command that can be
simplified by the new API, so I decided to rewrite it as an example.

The rewritten version is more flexible and doesn't actually need the
restrictions from the old version (such as checking that the commits
are connected). I still left the check for now to keep this patch
somewhat small. A subsequent commit will remove the restrictions.

1b3bcedd53 cli: label log/obslog template as "log"
It was removed at 522025e091 "log: remove unused and inconsistent `log`

the template output, let's re-add the "log" label.

The change in test_templater_upper_lower() is noop. Formatter no longer
emits reset sequence in the middle because the template is still labeled.

4474577ceb fileset: parse cwd/root-glob patterns
Mercurial appears to resolve cwd-relative path first, so "glob:*.c" could be
parsed as "**/*.c" if cwd was literally "**". It wouldn't practically matter,
but isn't correct. Instead, jj's parser first splits glob into literal part
and pattern. That's mainly because we want to parse the user input texts into
type-safe objects, and (RepoPathBuf, glob::Pattern) pairs are the simplest
ones. The current parser can't handle patterns like "foo/*/.." (= "foo" ?),
and errors out. I believe this restriction is acceptable.

Unlike literal paths, the 'glob:' pattern anchors to the whole file path. I
don't think "prefix"-matching glob is useful, and making it the default would
be rather confusing.

8ce099470b cargo: explicitly indicate paths to publish
Running `cargo publish` from a non-colocated repo (such as my usual
repo) is currently quite scary because it uploads all non-hidden
files, even if they're ignored by `.gitignore`
(https://github.com/rust-lang/cargo/issues/2063). I noticed this a
while ago and have always run the command from a fresh clone since
then. To avoid the need for that, let's use the workaround mentioned
on the bug, which is to explicitly list patterns we want to publish.

fc49d35daa Fix empty files can't be selected in the builtin diff editor
This fixes several issues that made working with empty files difficult using
the builtin diff editor.

1. The scm-record library used for the editor expects each file to have at
least one section. For new empty files this should be a file mode section. jj
wasn't rendering this mode section, which prevented empty files from being
selected at all.

2. The scm-record library returns `SelectedContents::Absent` if the file has no
contents after the diff editor is invoked. This can be because of several
reasons: 1) the file is new and empty; 2) the file was empty before and is
still empty; 3) the file has been deleted. Perhaps this is a bug in scm-record
and it should return `SelectedContents::Unchanged` or
`SelectedContents::Present` if the file hasn't been deleted. Until this is
patched upstream, we can work around it by disambiguating these cases.

See https://github.com/arxanas/scm-record/issues/26 for the upstream bug.
