namespaces: make the constructor into named args None of the arguments are truly optional but this makes adding future arguments more robust and perhaps optional.

dispatch: only check compatibility against major and minor versions (BC) Extensions can declare compatibility with Mercurial versions. If an error occurs, Mercurial will attempt to pin blame on an extension that isn't marked as compatible. While all bets are off when it comes to the internal API, my experience has shown that a monthly/patch release of Mercurial has never broken any of the extensions I've written. I think that expecting extensions to declare compatibility with every patch release of Mercurial is asking a bit much and adds little to no value. This patch changes the blame logic from exact version matching to only match on the major and minor Mercurial versions. This means that extensions only need to mark themselves as compatible with the major, quarterly releases and not the monthly ones in order to stay current and avoid what is almost certainly unfair blame. This will mean less work for extension authors and almost certainly fewer false positives in the blame attribution.

test-extension: use a realistic Mercurial version Mercurial doesn't define the 3rd "patch" version field for major releases. Don't use it in tests.

test-extension: improve test readability There was a mountain of text in this file that made reading the tests difficult. Inserting some line breaks greatly improves the situation.

bundle2: enforce parttype as alphanumerical The binary format description has always stated that the parttype should be simple, but it was never really enforced. Recent discussions have convinced me we want to keep the part type simple and easy to debug. There is enough extensibility in the rest of the format.

tests: conditionalize test-tools.t for Windows support I still get the following diff on Windows 7 with NTFS.

dirstate: ignore negative debug.dirstate.delaywrite values - they crashed it Sleep can only travel forward in time, not back.

linkrev: use the right manifest content when adjusting linrev (issue4499) When the manifest revision is stored as a delta against a non-parent revision, '_adjustlinkrev' could miss some file update because it was using the delta only. We now use the 'fastread' method that uses the delta only when it makes sense. A test showcasing on the of possible issue have been added.

unpacker: fix missing arg for py2.4

branchcache: make _rbcrevslen handling more safe self._rbcrevslen is used to keep track of the number of good records on disk. It should thus not be updated before the records actually have been written to disk.
