branchmap: allow to use cache of subset Filtered repository are *subset* of unfiltered repository. This means that a filtered branchmap could be use to compute the unfiltered version. And filtered version happen to be subset of each other: - "all() - unserved()" is a subset of "all() - hidden()" - "all() - hidden()" is a subset of "all()" This means that branchmap with "unfiltered" filter can be used as a base for "hidden" branchmap that itself could be used as a base for unfiltered branchmap. unserved < hidden < None This changeset implements this mechanism. If the on disk branchcache is not valid we use the branchcache of the nearest subset as base instead of computing it from scratch. Such fallback can be cascaded multiple time is necessary. Note that both "hidden" and "unserved" set are a bit volatile. We will add more stable filtering in next changesets. This changeset enables collaboration between no filtering and "unserved" filtering. Fixing performance regression introduced by 47f00b0de337 [ original upstream message ]

localrepo: filter unknown nodes from the phasecache on destroyed When commit is followed by strip (qrefresh), phasecache contains nodes that were removed from the changelog. Since phasecache is filecached with .hg/store/phaseroots which doesn't change as a result of stripping, we have to filter it manually. If we don't write it immediately, the next time it is read from disk the nodes will be filtered again. That's what happened before, but there's no reason not to write it immediately. The change in test-keyword.t is caused by the above. [ original upstream message ]

strip: do not update branchcache during strip (issue3745) At this moment, the cache is invalid, and will be thrown away. Later the strip function will call the `localrepo.destroyed` method that will update the branchmap cache. [ original upstream message ]

branchmap: move validity logic in the object itself In several place, We check if a branchcache is still valid regarding the current state of the repository. This changeset puts this logic in a method of the object that can be reused when necessary. A branch map is considered valid whenever it is up to date or a strict subset of the repository state. The change will help making branchcache aware of filtered revision. The change in keyword is expected. the branch cache is actually invalid after the amend. The previous check did not detected it.

run-tests: fix whitespace nonsense [ original upstream message ]

run-tests: on windows, put correct python at front of PATH The older approach of trying to copy the python executable into the test directory was doomed to fail. There remains one weakness with this approach: if you've run "make local", tests may pick up the wrong extension DLLs from inside the source tree. I don't know why this happens. A reasonable workaround for now is to test either using --local or with a working directory that does not contain built DLLs. [ original upstream message ]

run-tests: support running tests in parallel on windows Previously, we used os.spawnvp, which doesn't exist on Windows, and isn't needed anyway (the command line begins with an absolute path). We also need a slightly more convoluted way to wait for processes without specifying an order on Windows, as it lacks os.wait. [ original upstream message ]

run-tests: remove resultslock since it serves no useful purpose Each child process has its own copy of the results dict, so all access to the results dict is serial. [ original upstream message ]

run-tests: use pickle to send results from children to parent JSON would probably be preferable, but it isn't available for Python 2.4 or 2.5. [ original upstream message ]
