windows: drop Python2.4 specific hack for directory not found handling A good Python 2.4 hack is a removed Python 2.4 hack.

notify: drop import required by Python 2.4 Toto, I've a feeling we're not in anno 2004 anymore.

patchbomb: stop explicit import required by Python 2.4 Ding Dong, the witch is dead!

pager: drop python 2.4 hack around subprocess Farewell, we do not need you anymore.

check-code: drop ban of 'val if cond else otherval' construct We now have access to this horrible but less bad than 'cond and val or otherval' syntax.

check-code: entirely drop the 'non-py24.py' file from the test There are no Python 2.4 related errors remaining.

check-code: drop the 'format' built-in I'm not clear what it is doing, but one who knows what it is about can now make use of it.

check-code: drop ban of str.format After discussion with Augie and Matt, we are fine with it being introduced in the code base.

statichttprepo: remove wrong getattr ladder At least as far back as Python 2.6 the .code attribute is always defined, and to the best of my detective skills a .getcode() method has never been a thing.

match: explicitly naming a subrepo implies always() for the submatcher The files command supports naming directories to limit the output to children of that directory, and it also supports -S to force recursion into a subrepo. But previously, using -S and naming a subrepo caused nothing to be output. The reason was narrowmatcher() strips the current subrepo path off of each file, which would leave an empty list if only the subrepo was named. When matching on workingctx, dirstate.matches() would see the submatcher is not always(), so it returned the list of files in dmap for each file in the matcher- namely, an empty list. If a directory in a subrepo was named, the output was as expected, so this was inconsistent. The 'not anypats()' check is enforced by an existing test around line 140: $ hg remove -I 're:.*.txt' sub1 Without the check, this removed all of the files in the subrepo.

context: don't complain about a matcher's subrepo paths in changectx.walk() Previously, the first added test printed the following: $ hg files -S -r '.^' sub1/sub2/folder sub1/sub2/folder: no such file in rev 9bb10eebee29 sub1/sub2/folder: no such file in rev 9bb10eebee29 sub1/sub2/folder/test.txt One warning occured each time a subrepo was crossed into. The second test ensures that the matcher copy stays in place. Without the copy, the bad() function becomes an increasingly longer chain, and no message would be printed out for a file missing in the subrepo because the predicate would match in one of the replaced methods. Manifest doesn't know anything about subrepos, so it needs help ignoring subrepos when complaining about bad files.

ssh: capture output with bundle2 again (issue4642) I just discovered that we are not displaying ssh server output in real time anymore. So we can just fall back to the bundle2 output capture for now. This fix the race condition issue we where seeing in tests. Re-instating real time output for ssh would fix the issue too but lets get the test to pass first.

revset: optimize not public revset This patvh speeds up the computation of the not public() changeset and incidentally speed up the computation of divergents() changeset on our big repo by 100x from 50% to 0.5% of the time spent in smartlog with evolve. In this patch we optimize not public() to _notpublic() (new revset) and use the work on phaseset (from the previous commit) to be able to compute _notpublic() quickly. We use a non-lazy approach making the assumption the number of notpublic change will not be in the order of magnitude of the repo size. Adopting a lazy approach gives a speedup of 5x (vs 100x) only due to the overhead of the code for lazy generation.

phases: add set per phase in C phase computation To speed up the computation of draft(), secret(), divergent(), obsolete() and unstable() we need to have a fast way of getting the list of revisions that are in draft(), secret() or the union of both: not public(). This patch extends the work on phase computation in C and make the phase computation code also return a list of set for each non public phase. Using these sets we can quickly obtain all the revisions of a given phase. We do not return a set for the public phase as we expect it to be roughly the size of the repo. Also, it can be computed easily by substracting the entries in the non public phases from all the revs in the repo.

match: rename _fmap to _fileroots for clarity fmap isn't a very descriptive name for the set of the match's files.
