I plan to provide a richer version of `TreeDiffEntry` with copy info
(and to make `TreeDiffEntry` itself "poorer"). Most callers want to
know about copies/renames, but at least working copy implementations
probably don't. This patch adds separate `diff_stream()` and
`diff_stream_with_copies()` so we can provide the simpler interface
for callers that don't need copy info.
The support for copy tracing is already simply added to the stream
just before yielding the item, so we can easily implement it as a
stream adapter. That ensures that we use the same logic for the
iterator- and stream-based versions. More importantly, it enables
further cleanups and a simpler interface.
MergedTreeVal was roughly equivalent to Merge<Option<Cow<_>>. As we've dropped
support for the legacy trees, it can be simplified to Merge<Option<&_>>.
- force each diff command to explicitly enable copy tracking
- enable copy tracking in diff_summary
- post-process for diff iterator
- post-process for diff stream
- update changelog
- use a single commit instead of an array of them. This simplifies the
implementation. A higher level api can wrap this when an array of
commits is desired and those semantics are figured out.
- since this API is directly 1-1 on parents, there are no conflicts
- if we introduce a higher level API that handles lists of commits, we
may need to restore the conflict/resolved distinction, but for now
simplify
I considered making `MergedTree` just a newtype (1-tuple) but I went
with a struct instead because we may want to add copy information in a
separate field in the future.
Author dates and committer dates can be filtered like so:
committer_date(before:"1 hour ago") # more than 1 hour ago
committer_date(after:"1 hour ago") # 1 hour ago or less
A date range can be created by combining revsets. For example, to see any
revisions committed yesterday:
committer_date(after:"yesterday") & committer_date(before:"today")
This basically reverts 20eb9ecec1 "git: don't abandon HEAD commit when it
loses a branch." I think the new behavior is more consistent because the Git
HEAD is equivalent to @- in jj, so it shouldn't be considered a named ref.
Note that we've made old HEAD branch not considered at 92cfffd843 "git: on
external HEAD move, do not abandon old branch."
#4108
The text pattern is applied prior to comparison as we do in Mercurial. This
might affect hunk selection, but is much faster than computing diff of full
file contents. For example, the following hunk wouldn't be caught by
diff_contains("a") because the line "b\n" is filtered out:
- a
b
+ a
Closes#2933
Since fileset and revset languages are syntactically close, we can reparse
revset expression as a fileset. This might sound a bit scary, but helps
eliminate nested quoting like file("~glob:'*.rs'"). One oddity exists in alias
substitution, though. Another possible problem is that we'll need to add fake
operator parsing rules if we introduce incompatibility in fileset, or want to
embed revset expressions in a fileset.
Since "file(x, y)" is equivalent to "file(x|y)", the former will be deprecated.
I'll probably add a mechanism to collect warnings during parsing.
Adds support for revset functions `tracked_remote_branches()` and
`untracked_remote_branches()`. I think this would be especially useful
for configuring `immutable_heads()` because rewriting untracked remote
branches usually wouldn't be desirable (since it wouldn't update the
remote branch). It also makes it easy to hide branches that you don't
care about from the log, since you could hide untracked branches and
then only track branches that you care about.
Maybe it'll also be good to keep RevsetExpression::Union(_) flattened, but
that's not needed to get around stack overflow. The constructed expression
tree is balanced.
test_expand_symbol_alias() is slightly adjusted since there are more than
one representation for "a|b|c" now.
Fixes#4031
Partially resolve a 1.5‐year‐old TODO comment.
Add opt‐in syntax for case‐insensitive matching, suffixing the
pattern kind with `-i`. Not every context supports case‐insensitive
patterns (e.g. Git branch fetch settings). It may make sense to make
this the default in at least some contexts (e.g. the commit signature
and description revsets), but it would require some thought to avoid
more confusing context‐sensitivity.
Make `mine()` match case‐insensitively unconditionally, since email
addresses are conventionally case‐insensitive and it doesn’t take
a pattern anyway.
This currently only handles ASCII case folding, due to the complexities
of case‐insensitive Unicode comparison and the `glob` crate’s lack
of support for it. This is unlikely to matter for email addresses,
which very rarely contain non‐ASCII characters, but is unfortunate
for names and descriptions. However, the current matching behaviour is
already seriously deficient for non‐ASCII text due to the lack of any
normalization, so this hopefully shouldn’t be a blocker to adding the
interface. An expository comment has been left in the code for anyone
who wants to try and address this (perhaps a future version of myself).
Forgetting a workspace removes its working-copy commit, so it makes
sense for it to be abandoned if it is discardable just like editing a
new commit will cause the old commit to be abandoned if it is
discardable.
Currently, if two workspaces are editing the same discardable commit and
one of them switches to editing a different commit, it is abandoned even
though the other workspace is still editing it. This commit treats
workspaces as referencing their working-copy commits so that they won't
be abandoned.
Fixes#2476.
Previously, if there was a change id match within the short prefix
lookup set, `jj` would not look for commits with that same change id
outside the short prefix set. So, it wouldn't find the conflicted
commits for a commit with a divergent (AKA conflicted) change id.
It's common to create empty working-copy commits while using jj, and
currently the author timestamp for a commit is only set when it is first
created. If you create an empty commit, then don't work on a repo for a
few days, and then start working on a new feature without abandoning the
working-copy commit, the author timestamp will remain as the time the
commit was created rather than being updated to the time that work began
or finished.
This commit changes the behavior so that discardable commits (empty
commits with no description) by the current user have their author
timestamps reset when they are rewritten, meaning that the author
timestamp will become finalized whenever a commit is given a description
or becomes non-empty.
Since we've split (local, remotes) branches to (locals, remotes { branches }),
.has_branch() API no longer makes much sense. Callers often need to check if
a remote branch is tracked.
