prepush: rewrite most of the code from scratch For servers with branchmap support, the algorithm now works as follows: 1. A list of branches in outgoing changesets is created. 2. Using the remote branchmap, a check for new branches is performed. 3. A map (from branch to head list) of locally known remote heads before the push is created, and one which, after step 4, will contain the locally known remote heads after the push. 4. The post-push head map is updated with the outgoing changesets, using the branch cache update mechanism. 5. A check for new heads is performed, by comparing the length of the head list before and after push, for each branch. If there are new heads, an error depending on whether or not there are incoming changes on the branch, is returned. 6. If the push is allowed, a warning is written if there are incoming changes on any branches involved in the push. For old servers, an algorithm similar to step 4-6 above is used to check for new topological heads only. Two bugs are also fixed: 1. Sometimes you would be allowed to push new branch heads without --force. A test for this case was added. 2. You would get the "note: unsynced remote changes!" warning if there were any incoming changesets, even if they were on unrelated branches.

workingctx: correctly compute the flag for noexec filesystems+merge This bug happens if the filesystem doesn't support exec-bit, during merges, for example in 24ed7a541f23 on the hg repo. If f is not in p1, but is in p2 and has the x-bit in p2, since the dirstate is based on p1, and the FS doesn't support the exec-bit, the dirstate can't "guess" the right bit. We instead fix it in workingcontext.flags()/manifest.

revlog: fix lazyparser.__iter__() to return all revisions (issue2137) Previously, it only returned revisions that were in the revlog when it was originally opened; revisions added since then were invisible. This broke revlog._partialmatch() and therefore repo.lookup(). (Credit to Benoit Boissinot for simplifying my original test script and for the actual fix.)

revlog: factor out _maxinline global. This lets us change the threshold at which a *.d file will be split out, which should make it much easier to construct test cases that probe revlogs with a separate data file. (issue2137)

prepush: backed out refactoring It has some problems in corner cases and will fail on a test recently introduced on stable. Will maybe be reintroduced later, in a better version.

prepush: add more test cases

prepush: fix bug in warning message selection In certain situations you would be told "you should pull and merge" even when there is nothing to pull.

verify: improve progress descriptions For GUIs, the progress bar is disconnected visually from the text that is output by ui.write(), so it's better to be a little bit redundant in naming the status. "checking" is redundant, since the user is running the verify command. 'changesets', 'manifests', etc, tell the user what is being checked (the entity being counted in the progress bar.

pylint, pyflakes: remove unused or duplicate imports

Fix --blacklist when --jobs > 1 in run_tests.py. The options parsing logic replaces the options.blacklist initial value, a list of filenames, with a dict of test names to filenames. When runchildren rebuilds the command line to launch child processes the dict is flattened and provided as a malformed argument when a filename is expected. Fix is to remove the blacklist option from child invocations since the filtering is handled in the parent anyway.
