py3: cast attribute name to sysstr in clearcachedproperty()

py3: whitelist three more passing test caught by buildbot The number of failing test is back to two digits. Differential Revision: https://phab.mercurial-scm.org/D5293

tests: make test-check-module-imports more robust It failed for me without this in this way: tests/test-commandserver.t:19: relative import of stdlib module tests/test-lfs-serve.t:108: relative import of stdlib module tests/test-lfs-serve.t:255: relative import of stdlib module tests/test-lfs-serve.t:362: relative import of stdlib module tests/test-lfs-serve.t:406: relative import of stdlib module tests/test-lock.py:9: imports not lexically sorted: silenttestrunner < unittest, True, True tests/test-lrucachedict.py:5: imports not lexically sorted: silenttestrunner < unittest, True, True tests/test-match.py:5: imports not lexically sorted: silenttestrunner < unittest, True, True tests/test-remotefilelog-datapack.py:15: imports not lexically sorted: silenttestrunner < unittest, True, True tests/test-remotefilelog-histpack.py:14: imports not lexically sorted: silenttestrunner < unittest, True, True tests/test-simplekeyvaluefile.py:4: imports not lexically sorted: silenttestrunner < unittest, True, True tests/test-sshserver.py:6: imports not lexically sorted: silenttestrunner < unittest, True, True This is because every module is considered a stdlib module, because the stdlib_prefixes is /usr, and my repo is in /usr/local/home, which means that sys.path contains a couple of /usr/local/home/../hg/.. entries that count as "in the stdlib". Fix this by preventing any path in sys.path that's inside the mercurial source from being considered "in the stdlib". Differential Revision: https://phab.mercurial-scm.org/D5294

push: add --publish flag to change phase of pushed changesets This flag is copied from topic extension, where it proved to be useful. It makes all pushed changesets public on both ends if the push succeeds. Doesn't currently work for any subrepos that are implicitly pushed together with their owner repo.

match: reformat `syntaxes` dictionary for better maintainability

match: provide and use a quick way to escape a single byte The previous function has a lot of overhead (including being a function). In the `_globre` case, we always escape a single byte. So we provide a dictionary dedicated to this use case. We directly use the dictionary to avoid a function call, these are expensive in Python. Again, this raise a very significant performance gain: Before: ! wall 0.059793 comb 0.060000 user 0.060000 sys 0.000000 (median of 100) After: ! wall 0.020390 comb 0.020000 user 0.020000 sys 0.000000 (median of 146) Total improvement for the full series: Before: ! wall 0.153153 comb 0.150000 user 0.150000 sys 0.000000 (median of 66) After: ! wall 0.020390 comb 0.020000 user 0.020000 sys 0.000000 (median of 146)
