It is important to mention tracking branches and listing branches. This topic is important now that `jj log` does not show branches
`jj git clone` says it fetched by default.
The demo has become more about navigating a Git remote, so I reworded
the README accordingly, shifting the focus more to "Git remote
compatibility" and away from "We include a Git repo". Both are
important, but these skills seem important for beginners.
This updates demos to the point where they can run without
warnings. Some of them become less clear, this is addressed
(where I noticed it) in follow-up commits.
Fixes#3209
It seems everyone agrees that `obslog` is not an intuitive name. There
was some discussion about alternatives in #3592 and on #4146. The
alternatives included `evolution`, `evolutionlog`, `evolog`,
`rewritelog`, `revlog`, and `changelog`. It seemed like
`evolution-log`/`evolog` was the most popular option. That also
matches the command's current help text ("Show how a change has
evolved over time").
As reported in #4394, at least `test_show_command::test_show_basic`
can fail when run with a narrow terminal. This patch sets
`COLUMNS=100` in the environment when running tests so the CLI uses
that value instead of using the width of the user's terminal.
This avoids an MkDocs warning.
I put it into Design Docs, since people who follow the link to the
roadmap might be interested in those.
It's not a perfect place for it, but it seems better than "Technical
Details" or "Contributing" (which might make people think that they have
to read or follow the roadmap before contributing).
This doesn't provide any benefit yet bit I think we've known for a
while that we want to make the backend write methods async. It's just
not been important to Google because we have the local daemon process
that makes our writes pretty fast. Regardless, this first commit just
changes the API and all callers immediately block for now, so it won't
help even on slow backends.
When building this project with [Nix/Crane](https://github.com/ipetkov/crane/discussions/693), if the `jj-cli` dependency is specified in `Cargo.toml` as a git-based crate, `cargo vendor` splits this workspace up into sub-crate directories, which causes `cargo metadata` to fail when searching for relative deps in the workspace root.
This commit simply changes how the crate version is determined, using Cargo's built-in environment variable [`CARGO_PKG_VERSION`](https://doc.rust-lang.org/cargo/reference/environment-variables.html)
MkDocs did not render this list in
https://martinvonz.github.io/jj/prerelease/config/#node-style properly
before.
I don't understand the reason; we have other lists that are formatted
similarly to how this one was, and they look fine in MkDocs. This might
be a bug in one of the MkDocs extensions for lists that we use.
Right now, renamed and copied files don't have any color in the output
of `jj status`, and it makes them stand out. I think it's reasonable to
color renamed files the same as modified files, since renaming is like
modifying the path, and to color copied files the same as added files,
since they're basically just added files that happen to have similar
contents to an existing file.
The question "How do I avoid committing changes to files?" comes up a lot in
chat, and the solution is not obvious. It will be useful to have a description
with an example we can link to.
The wording of the similar question "How can I keep my scratch files in the
repository?" was tweaked to emphasize the difference between keeping untracked
files in the workspace and keeping changes tracked files out of published
history.
This avoids cloning `UserSettings` and some other data. I haven't
attempted to measure the performance impact (I expect it's tiny); this
is more about clarifying that there are not multiple different
versions of these fields.
This wraps all the fields in `CommandHelper` in an `Rc` so
`CommandHelper` itself becomes cheap to clone (thanks to @yuja for the
idea). I'll use that next to avoid some cloning in
`WorkspaceCommandHelper`.
This helps resolve diverged refs by abandoning both sides:
D ref = [D]
|\
| C C ref = [B - D + C]
| | |
B | B | B ref = [B - D + A]
|/ |/ |
A A A A ref = [A - D + A]
This is closer to the original behavior before 5e8d7f8c "rewrite: update
references after rewriting all commits." References can move to divergent
commits, so they should propagate further if there are more rewrites. See
the inline comment for subtle behavior difference.
We could instead replay parent_mapping in topological order, but we would
still need to flatten abandon records.
"Concurrent" operations are not necessarily actually concurrent, so
"divergent" seems like a better name. And "reconcile" seems like a
better term for merging them, though we also sometimes use "merge".
Like https://github.com/martinvonz/jj/pull/4189, this allows extensions the ability to load the repo in an environment where the local filesystem is not accessible. This change allows such extensions to exist at the CLI layer where jj is invoked as a subprocess, rather than a library (common in testing).
I just choose "clru" because it already exists in our dependency tree thorough
gix. I don't think LRU is the best cache eviction policy for our use case (a
simpler FIFO-based one might be good enough?), but it wouldn't matter for CLI
or GUI use case. I don't see significant performance degradation with "jj log
--stat -n1000".
RwLock is replaced with Mutex since get() is inherently a mutable operation.
