tests: mark test-check-interfaces.py as requiring a repo This was failing our 4.6rc1 build like this: mercurial.error.RepoError: repository /tmp/build-debs.zMTRhC/src-4.6rc1 not found Differential Revision: https://phab.mercurial-scm.org/D3425

sshpeer: reflect actual command activity one handshake The output from devel-peer-request is expected to give data about request and roundtrip done to the server. Changeset a9cffd14aa04 changed some of that by grouping hello and between commands call. However, the old sequence of command was "emulated" in sshpeer. Update the sshpeer to reflect this grouping of commands and update the tests that use it.

tests: drop a useless glob in test-infinite-bundlestore.t With the previous breakage tamed, the lack of test output difference was causing the test runner to report "no result code from test" because of this glob.

infinitepush: ensure fileindex bookmarks use '/' separators (issue5840) After loading up with status messages, I noticed that the subsequent matcher was rejecting 'scratch\mybranch' on Windows. No bookmarks were reported back, and the tests subsequently failed. I did a search for 'match', and nothing else looks like it needs to be fixed up, but someone who understands this code should also take a look. I also tried setting `infinitepush.branchpattern=re:scratch\\.*` in library-infinitepush.sh without this change, but that didn't work. Still, should we ban '\' in these bookmarks to avoid confusion? I thought I saw code that sandwiches a pattern between 're:^' and '.*', so perhaps regex characters will need special care? I also noticed comments in externalbundlestore.{read,write} that it won't work on Windows because of opening an open file. But I don't see a test failure, so this may lack test coverage.

interfaceutil: module to stub out zope.interface The startup time of `hg` increased during the 4.6 development cycle. A cause of that was importing more modules and doing more work at module import time. The import of zope.interface and the declaring of various interfaces is partially responsible for the startup time regression. Our current usage of zope.interface doesn't do much at run time: we are merely declaring interfaces and stating that certain types implement various interfaces. Core Mercurial is not (yet) using of any of zope.interface features that actually require that interface plumbing be defined. The only place we actually need the interface metadata is in test-check-interfaces.py. This commit establishes a new interfaceutil module. It exposes the subset of the zope.interface API that we currently use. By default, the APIs no-op. But if an environment variable is set, we export the real zope.interface APIs. Existing importers of zope.interface have been converted to use the new module. test-check-interfaces.py has been updated to define the environment variable so the real zope.interface is used. The net effect of this change is we stop importing 9 zope.interface.* modules and we no longer perform interface bookkeeping when registering interfaces. On my i7-6700K on Linux, a shell loop that runs `hg log -r .` 300 times on a repo with 1 commit shows a significant CPU time improvement (average of 4 runs): 4.5: 14.814s before: 19.028s after: 16.945s And with `run-tests.py -j10` (single run): 4.5: ~3100s (~51.7m) before: ~4450s (~74.2m) after: ~3980s (~66.3m) So this claws back about half of the regressions in 4.6.
