test: copy test-push-http.t to testpush-http-bundle1.t We want to keep both code paths tested. The test is a bit too extensive to simply introduce dual testing in it, so we make a copy for each protocol version.

tests: add (?) flag for optional lines When the test engine fails to match output on a line marked with (?), it will simply continue to the next expected line and try again. This allows simplifying tests that have either version-specific or non-fixed behavior, for instance: $ coin-flip heads (?) tails (?) (There's no form of back-tracking attempted, so optional matches should be specific.)

templatekw: display active bookmark more consistently (issue4552) (BC) Previously, the template keyword '{activebookmark}' would only display the active bookmark if it was also pointing to the working directory's parent. Meanwhile, the '{active}' subkeyword of the '{bookmarks}' keyword displays the active bookmark regardless of whether it also points to the working directory's parent. This is confusing. Consider the output of these two templates: $ hg log -T '{activebookmark}\n' -r indent $ hg log -T '{bookmarks % "{bookmark}"}\n' -r indent indent This is the current behavior that can arise after, eg, a pull moves a bookmark out from under you. After this patch, the first template will also return the active bookmark that points to a revision, even if it is not the current parent of the working directory. A test has been added to show the new behavior.

revrange: build spanset from x:y range This slightly improves the performance in the optimal case: % hg log -R mozilla-central -r0:tip -l1 --time (before) time: real 0.050 secs (user 0.040+0.000 sys 0.010+0.000) (after) time: real 0.020 secs (user 0.000+0.000 sys 0.010+0.000)

revrange: build balanced tree of addsets from revisions (issue4565) This reduces the stack depth from O(n) to O(log(n)). Therefore, repeated -rREV options will never exceed the Python stack limit. Currently it depends on private revset._combinesets() function. But at some point, we'll be able to drop the old-style parser, and revrange() can be completely rewritten without using _combinesets(): trees = [parse(s) for s in revs] optimize(('or',) + trees) # combine trees and optimize at once ... Blockers that prevent eliminating old-style parser: - nullary ":" operator - revrange(repo, [intrev, ...]), can be mapped to 'rev(%d)' ? - revrange(repo, [binnode, ...]), should be banned ?

revrange: clean up meaningless reconstruction of sets They just exist for deduplication that was removed by the previous patch.

revrange: drop unnecessary deduplication of revisions Because "l" is a smartset, duplicated entries are omitted by addsets.

summary: move the parents phase marker to commit line (issue4688) The phase of the pending commit depends on the parent of the working directory and on the phases.newcommit configuration. First, this information rather depend on the commit line which describe the pending commit. Then, we only want to be advertised when the pending phase is going to be higher than the default new commit phase. So the format will change from $ hg summary parent: 2:ab91dfabc5ad foo parent: 3:24f1031ad244 tip bar branch: default commit: 1 modified, 1 unknown, 1 unresolved (merge) update: (current) phases: 1 secret (secret) to parent: 2:ab91dfabc5ad foo parent: 3:24f1031ad244 tip bar branch: default commit: 1 modified, 1 unknown, 1 unresolved (merge) (secret) update: (current) phases: 1 secret

tags: support setting hgtags fnodes cache entries An upcoming patch will teach bundle2 to transfer .hgtags fnodes values. To support this, we need to support inserting values into the cache. Add functionality to do that.

tags: support reading tags cache without populating An upcoming patch will teach the bundle2 protocol to transfer .hgtags fnodes to the client. We don't want this to incur any extra work at serve time. Create an optional cache query mode that doesn't populate the cache as a side-effect.
