rebase: don't rebase obsolete commits with no successor This patch avoids unnecessary conflicts to resolve during rebase for the users of changeset evolution. This patch modifies rebase to skip obsolete commits with no successor. It introduces a new rebase state 'revpruned' for these revisions that are being skipped and a new message to inform the user of what is happening. This feature is gated behind the config flag experimental.rebaseskipobsolete When an obsolete commit is skipped, the output is: note: not rebasing 7:360bbaa7d3ce "O", it has no successor

rebase: fix a typo in test-rebase-obsolete We had left a lonely single quote where it shouldn't be!

hgweb: unify import style of error classes It will be enforced by the import checker.

hgweb: do not import templatefilters.revescape and websub as symbol It will be enforced by the import checker.

hgweb: alias ui module as uimod It will be enforced by the import checker.

mergestate.commit: factor out making the list of records Will aid in testing.

mergestate: move _read() call to read constructor With this patch, mergestate.clean() will no longer abort when it encounters an unsupported merge type. However we hold off on testing it until backwards compatibility is in place.

debugmergestate: explain why we create mergestate objects directly We would normally use the read() constructor, but in this case it's fine because - we implement our own reading layer, so the extra parsing done by read() is unnecessary - read() can raise an exception for unsupported merge state records, but here we'd like to handle that separately - debugmergestate needs to be privy to mergestate internals anyway

debugdirstate: convert keyword parameters to **opts Removes the named arguments and replaces them by accessing opts. This will be used in the next patch in the series because we'll be adding more flags to debugdirstate

convert: changed test's progress output format to ignore estimate On my machine, whenever I run all test with a high -j value, test-convert-git.t would consistently fail by displaying an estimate. This patch removes that value from the output.

mq: use repo._bookmarks.recordchange instead of repo._bookmarks.write Before this patch, mq was using repo._bookmarks.write. This patch replaces this code with the recommended way of saving bookmarks changes: repo._bookmarks.recordchange.

mq: indentation change to make the next patch more legible We put the code to be indented in the next patch in a "if True:" block to make it easier to review.

bookmarks: use repo._bookmarks.recordchange instead of repo._bookmarks.write We move from the old api repo._bookmarks.write to the new api repo._bookmarks.recordchange.

localrepo: put bookmark move following commit in one transaction Before this patch, making a commit on a local repo could move a bookmark and both operations would not be grouped as one transaction. This patch makes both operations part of one transaction. This is necessary to switch to the new api to save bookmarks repo._bookmarks.recordchange if we don't want to change the current behavior of rollback. Dirstate change happening after the commit is done is now part of the transaction mentioned above. This leads to a change in the expected output of several tests. The change to test-fncache happens because both lock are now released in the same finally clause. The lock release is made explicitly buggy in this test. Previously releasing lock would crash triggering release of wlock that crashes too. Now lock release crash does not directly result in the release of wlock. Instead wlock is released at garbage collection time and the error raised at that time "confuses" python.

test-resolve.t: switch to mergestate.read() See previous patches for why we're doing this.
