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.

check-commit: make foo_bar naming regexp less greedy \s is equivalent to the character class [ \t\n\r\f\v]. Using \s+ in a regular expression against input with multiple lines may match across multiple lines. For the regexp in question, "\+\s+" would match "+\n " and similar sequences, leading to false positives for functions that were included in diff context, after a modified hunk.

test: use bundle2 in test-http Now that we have a bundle1 version of this test, we can move the original to bundle2. This lets us handle the ouput change from using the bundle2 protocol earlier.

test: copy test-http.t to test-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.

test: use bundle2 in test-ssh Now that we have a bundle1 version of this test, we can move the main version to bundle2. This lets us handle the ouput change from using the bundle2 protocol earlier.

test: copy test-ssh.t to test-ssh-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.

test: lock test-unbundlehash to bundle1 usage It is testing a bundle1 specific behavior. Bundle2 has its own way there. See inline comment for details.

test: use bundle2 in test-acl This test makes extensive use of --debug so moving to bundle2 based exchange has a massive impact. We do it early to reduce the noise create by a future usage of bundle2 as the default protocol.

test: use both bundle formats in test-pull-http It is valuable to have both formats tested.

test: use bundle2 in test-http-proxy The proxy test does not care about what protocol is used, but the new protocol implies different traffic (and therefore different log output). We switch it to bundle2 early to minimise the noise of using bundle2 for exchange by default.
