`version` now prints the short 12-byte git hash of the current commit, and this
is now prefixed with `g` to make it clear that the following characters are a
"g"it hash; we might use a `j` variant in the future, for example. The full
commit hash is still given when `--build-info` is provided.
I've wanted to make the Git support optional for a long time. However,
since everyone uses the Git backend (and we want to support it even in
the custom binary at Google), there hasn't been much practical reason
to make Git support optional.
Since we now use jj-lib on the server at Google, it does make sense to
have the server not include Git support. In addition to making the
server binary smaller, it would make it easier for us (jj team at
Googlle) to prove that our server is not affected by some libgit2 or
Gitoxide vulnerability. But to be honest, neither of those problems
have come up, so it's more of an excuse to make the Git support
optional at this point.
It turned out to be much simpler than I expected to make Git support
in the lib crate optional. We have done a pretty good job of keeping
Git-related logic separated there.
If we make Git support optional in the lib crate, it's going to make
it a bit harder to move logic from the CLI crate into the lib crate
(as we have planned to do). Maybe that's good, though, since it helps
remind us to keep Git-related logic separated.
It's been more than 6 months since we added support for dynamically
selecting the working copy implementation. This patch drops support
for selecting the default implementation of that and other stores.
This will hopefully help remove PartialEq from RevsetExpression. Some assertions
are duplicated so that AST->RevsetExpression transformation is covered by tests.
This addresses issue #3317, where as discussed we want to show the paths to
configuration files if they contain errors, to make it easier for the user to
locate them.
This is an alternative to https://github.com/martinvonz/jj/pull/3732. I
think it's pretty important to show the "latest" alias. I don't know a
way to not show any alias for "prerelease" in the version selector
without deleting all of them.
I'll have to then separately delete the directories for the aliases on
the gh-pages branch, so that the URL does not resolve to outdated pages.
The downsides are: this will break https://martinvonz.github.io/jj/main/... and
(only recently created) https://martinvonz.github.io/jj/nightly/... links. We
won't have an always-on demo of how well aliases work for when and if we adjust
how aliases (including the all-important latest alias) work in the future.
However, expanding on #3732 (comment), mike is now randomly alternating between
"nightly" and "main" being the first alias of prerelease (it never promised that
the set of aliases would be ordered). So, the version selector keeps switching
in which version it shows. Previously, this only affected the prerelease docs,
but now it also affects https://martinvonz.github.io/jj/latest/.
As we discovered in the `jj fix` tests,
`MergedTreeBuilder::write_tree()` doesn't try to resolve conflicts,
not even trivial ones. This patch fixes that.
This changes the documented behavior of `resolve()` since it was
previously documented to not change the arity unless all conflicts
were resolved.
I plan to use `resolve()` from `MergedTreeBuilder::write_tree()`.
The current implementation of `resolve()` on legacy trees just
pretended any conflicts were regular files. It's better to error
out. The function is only used in tests so far.
The goal is to remove special case from parsing functions and provide slightly
better error message. I don't know if we'd want to use "all:" in aliases, but
there are no strong reasons to disable it.
I just added "can be empty" since it seems obvious when it becomes empty if it
can be empty. AFAICT, the confusion in #3821 is whether or not "no parents"
falls back to root().
We can add a separate precedence/associativity table, but I think the ordered
list is good enough. Nullary :: and .. have no binding, but inserted after the
infix versions for brevity.
This commit adds an optional flag to be able to push commits with an
empty description to a remote git repo. While the default behavior is
ideal we might need to interact with a repo that has an empty commit
description in it. I ran into this issue a few weeks ago pushing commits
from an open source repo to an empty repo and had to go back to using
git for that push as I would not want to rewrite the history which was
many many years long just for that.
This flag allows users an escape hatch for pushing empty descriptions
for commits and they're sure that they want that behavior.
This commit adds the flag to the `git push` command and updates the docs
for the command. It also updates the original test to make sure that the
flag works as intended to reject the commit when not set and to allow
the commit when the flag is set.
Closes#2633
This simplifies the interface of helper functions. While revset doesn't have
top-level string pattern or integer literal, these parsing helpers could be
used to parse array subscript or n-th parent operator if any.
