The `testutils` module should ideally not be part of the library
dependencies. Since they're used by the integration tests (and the CLI
tests), we need to move them to a separate crate to achieve that.
Unfortunately, TOML requires quotes around the argument. So, the
usage is `jj --config-toml ui.color=\"always\"` in bash. The plan is
to eventually have a `--config` option with simpler syntax for
simple cases.
As discussed in https://github.com/martinvonz/jj/discussions/688.
If I'm reading this attribute correctly, it says that if the
`map_first_last` feature is enabled, then we should enable the
`map_first_last` feature, which seems like it would not have any
effect. We started getting warnings from the nightly compiler about
this line because it tries to enable a feature that's stable in that
version.
The idea is to (ab)use pest::error::Error type to pretty-print error
message with code span. pest::error::Error will be constructed upfront
to erase lifetime from Span<'i>/Position<'i>.
Baby step towards embedding matcher in RevsetExpression. If we had a fileset
language or regex pattern, we would probably want to parse it at this stage
so the syntax error can be reported without evaluation.
If you remove all refs from the backing Git repo and then run `jj git
import`, we would see that all commits disappeared from the Git repo,
so we would remove them from the jj repo too. However, we do that by
doing a history walk from old heads to the new heads, which includes
the root commit when the new heads is an empty set. That means that we
mark the root commit as abandoned, which led to a crash in
`rewrite.rs` (when we try pick the root commit's first parent to use
as parent for rebased commits).
I was trying to create a reproduction script for #412, but the script
ran into another bug first. The script removed all the local and
remote branches from the backing Git repo. I noticed that we would
then try to abandon all commits. We should still count Git HEAD's
target as visible and not try to abandon it. This patch fixes that.
Sometimes a tagged commit is not in any branch on the remote, but we
should still consider them upstream and not include them in the
default log template.
This was reported by @colemickens but now that I think about it, I
remember seeing such commits in the Git core repo (v1.4.4.5 and a few
commits before it were never merged into main).
We don't have a good way of testing this because we don't have a
command for creating tags.
Closes#681
The function has only one caller since 25b922cd0b and it's pretty
small. Inlining also means we can reuse the joined paths created in
it, so I did that by extracting variables for them.
Since 'merges()' just filters the candidates set per item, it doesn't need
a candidates argument. Perhaps, 'merges(x)' could be a predicate to select
merge commits within a subgraph 'x', but I don't know if that would be
useful.
Since 'filter(expr)' is identical to 'expr & filter()', it can be rewritten
in order to minimize the candidates set to be scanned.
The implementation is somewhat similar to revsetlang.optimize() of Mercurial,
but I've split the tree rewriting logic to several steps. I think that's good
for maintainability and should help us conclude that a recursion will
eventually terminate.
This helps to match '(filter, _) | (_, filter)' to rewrite the expression
tree. Only one predicate is allowed for now, but I think it can be extended
to internalize 'f(c) & g(c)' as '(g*f)(c)' to eliminate redundant lookup
of commit object.
I had `init.defaultBranch = main` in my global config (just being
rolled out internally at Google, it seems), which made
`test_import_refs_reimport_head_removed()` and
`test_fetch_initial_commit()` fail. This fixes it.
Since d56ae79d3f, `WorkingCopy` no longer reads `.gitignores`
directly from `$HOME/.gitignore`, so we don't need the workaround to
prevent it in the tests.
