The main reason for this change is that we now give variables different names
based on their types. This helps avoid confusion and makes intent clearer.
However, the type name `FileExecutableFlag` doesn't have a good shortening
(`file_exec_flag` is annoyingly long), so I also renamed the type to something
shorter, which makes the code more legible: easier to mentally parse and
quicker to type.
I removed `File` from the name both for length and because it doesn't really
help distinguish from the executable field in `TreeValue` (because that field
is nested under `TreeValue::File`). Instead, in the upcoming commits I update
comments to consistently use the terms 'on-disk' and 'in-repo' to respectively
refer to the fields in the `FileState` and `TreeValue` structs, which I find
is better for keeping the difference clear in my head.
I went with `Bit` in the new name just because I'm already changing it and I
prefer `exec_bit` slightly over `exec_flag` as the variable name.
If a submodule was created in a commit C on a remote repo, switching from any
commit after C to any commit before C (eg. `jj new C-`) will result in jj
starting to track the files introduced in the submodule.
This issue has popped up very frequently for chromium developers, who
get issues when attempting to check out an older version of chromium.
Fixes#4349
As a follow-up to #8115, this moves all references in the codebase to use the new website.
I didn't update the older CHANGELOG entries because I figured they're intended
to be immutable.
Deprecation warnings will be emitted for default "substring:" patterns. This
change will suppress them. Since "glob:" will be the new default, I made these
tests use "glob:" when both "exact:" and "glob:" work.
Tests for the revset filter functions aren't updated.
This adds support for tracking ignored and oversized files with `jj file track`.
Previously, `jj file track` would silently fail to track files that were ignored by
`.gitignore` or larger than `snapshot.max-new-file-size`. This commit introduces an
`--include-ignored` flag that allows users to explicitly track these files.
## Implementation
Added a `force_tracking_matcher` field to `SnapshotOptions` that overrides ignore rules
and size limits. When `--include-ignored` is specified, the file pattern matcher is
passed as `force_tracking_matcher`, allowing three checks in `FileSnapshotter` to bypass
their usual restrictions for directory ignores, file ignores, and file size limits.
## Tests
- `test_track_ignored_with_flag`: Verifies `.gitignore`d files can be tracked
- `test_track_large_file_with_flag`: Verifies oversized files can be tracked
- `test_track_ignored_directory`: Verifies ignored directories can be tracked recursively

After the previous commit, `MergedTree` and `MergedTreeId` are almost
identical, with the only difference being that `MergedTree` is attached
to a `Store` instance. `MergedTreeId` is also equivalent to
`Merge<TreeId>`, since it is just a wrapper around it.
In the future, `MergedTree` might contain additional metadata like
conflict labels. Therefore, I replaced `MergedTreeId` with `MergedTree`
wherever I think it would be required to pass this additional metadata,
or where the additional methods provided by `MergedTree` would be
useful. In any remaining places, I replaced it with `Merge<TreeId>`.
I also renamed some of the `tree_id()` methods to `tree_ids()` for
consistency, since now they return a merge of individual tree IDs
instead of a single "merged tree ID". Similarly, `MergedTree` no longer
has an `id()` method, since tree IDs won't fully identify a `MergedTree`
once it contains additional metadata.
This includes the fix for
https://github.com/BurntSushi/ripgrep/issues/3127. The fix let us
optionally allow unclosed character classes in .gitignore files. It is
allowed by default when using the `GitignoreBuilder` (as we do), so we
get the fix without code changes.
I'm planning to try to add conflict labels to `MergedTree` and
`MergedTreeId`, and it will be easier to add them if both are structs
with similar methods. Since we don't support reading/writing legacy
conflicts anymore (as far as I'm aware), I think it should be safe to
delete the `MergedTreeId::Legacy` variant now.
There are two major goals:
1. garbage-collect predecessor commits referenced by immutable commits.
2. show operations alongside predecessors in "jj evolog".
The predecessors field will be removed from the Commit object. Maybe we can
also remove (writer side of) the extras table from GitBackend.
"jj evolog" will traverse the operation history to build an evolution
graph. This will be slower than the current implementation, but it seems
tolerable for mid-size repository stored in a local disk.
(when the page cache is warm)
% time jj op log -T'"."' --no-graph | wc -c
50459
jj op log -T'"."' --no-graph 0.12s user 0.31s system 103% cpu 0.418 total
Suppose we're interested in recent modifications, the traversal can often be
terminate early. I also have an idea for indexing originating operations.
https://github.com/jj-vcs/jj/pull/6405
For old operations which didn't record predecessors, "jj evolog" will fall back
to commit.predecessor_ids(). That's why commit_predecessors is Option<_>.
We haven't had any reports of problems from people who opted in. Since
it's early in the release cycle now, let's now test it on everyone who
builds from head, so we get almost a month of testing from those
people before it's enabled by default in a released version.
This impacts lots of test cases because the change-id header is added
to the Git commit. Most are uninteresting. `test_git_fetch` now sees
some divergent changes where it used to see only divergent bookmarks,
which makes sense.
Move the `track` specific logic to track.rs, let print_snapshot_stats
handle just the default case.
Previously print_snapshot_stats would get called twice and could warn
twice about a file (if that file was both in the auto-track fileset as
well as in the fileset passed to `jj file track`), so now we merge the
snapshot stats and display appropriate hints for each file.
I'm going to add "[EOF]" marker to test that command output is terminated by
newline char. This patch ensures that callers who expect a raw output string
would never be affected by any normalization passes.
Some common normalization functions are extracted as CommandOutputString
methods.
In the case where the user has set `snapshot.auto-track` to something
other than `all()`, running `jj st` with a higher file size set just for
that command will not actually fix the user's problem, `jj file track`
needs to be called instead.
Storing the conflict marker length in the working copy makes conflict
parsing more consistent, and it allows us to parse valid conflict hunks
even if the user left some invalid conflict markers in the file while
resolving the conflicts.
This patch moves max_new_file_size() and conflict_marker_style() to CLI, but
there isn't a clear boundary whether the configuration should be managed by
UserSettings or not. I decided to move them to CLI just because we can eliminate
.optional() handling. The default parameters are defined in config/misc.toml.
As Martin spotted, the original code can't prevent "1.0GiB, maximum size allowed
is ~1.0GiB." I personally don't mind if the error message contained the exact
size, so I simply let it print both exact and human byte sizes unconditionally.
I think this provides a better UX than refusing any operation due to large
files. Because untracked files won't be overwritten, it's usually safe to
continue operation ignoring the untracked files. One caveat is that new large
files can become tracked if files of the same name checked out. (see the test
case)
FWIW, the warning will be printed only once if watchman is enabled. If we use
the snapshot stats to print untracked paths in "jj status", this will be a
problem.
Closes#3616, #3912
Since config::Value type was lax about data types, an integer value could be
deserialized through a string. This won't apply to new toml_edit-based value
types.
Adds a new "git" conflict marker style option. This option matches Git's
"diff3" conflict style, allowing these conflicts to be parsed by some
external tools that don't support JJ-style conflicts. If a conflict has
more than 2 sides, then it falls back to the similar "snapshot" conflict
marker style.
The conflict parsing code now supports parsing Git-style conflict
markers in addition to the normal JJ-style conflict markers, regardless
of the conflict marker style setting. This has the benefit of allowing
the user to switch the conflict marker style while they already have
conflicts checked out, and their old conflicts will still be parsed
correctly.
Example of "git" conflict markers:
```
<<<<<<< Side #1 (Conflict 1 of 1)
fn example(word: String) {
println!("word is {word}");
||||||| Base
fn example(w: String) {
println!("word is {w}");
=======
fn example(w: &str) {
println!("word is {w}");
>>>>>>> Side #2 (Conflict 1 of 1 ends)
}
```
It's a pretty frequent request to have support for turning off
auto-tracking of new files and to have a command to manually track
them instead. This patch adds a `snapshot.auto-track` config to decide
which paths to auto-track (defaults to `all()`). It also adds a `jj
track` command to manually track the untracked paths.
This patch does not include displaying the untracked paths in `jj
status`, so for now this is probably only useful in colocated repos
where you can run `git status` to find the untracked files.
#323
This one just tests with a larger value and a human-readable string (10KB).

For new users this results in a significantly better error output, that
actually shows them how to solve the problem, and why it happened.

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.)

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.
