setup.py, make: avoid problems with outdated, existing hgext/__index__.py* "make clean" already removed __index__.py[cdo], but not the __index__.py (automatically generated by "python setup.py build_hgextindex"). "setup.py build_hgextindex" did not generate a new index if file __index__.py[cdo] already existed, because if __index__.py was removed, the compiled file containing the old information was imported and used. Generate an empty file (with a new timestamp to generate a new .py[cdo]) instead and make mercurial.extensions ignore the unset docs attribute. One of the problems was a failed test-help.t, to reproduce: $ rm hgext/__index__.py* $ echo 'docs = {"mq": "dummy"}' > hgext/__index__.py $ make test-help.t With this a "make clean" or "python setup.py build_hgextindex" helps.

factotum: initialize global variables to suppress pyflakes warning

color: don't fail on error messages when no curses (issue4237) The error only occured when Python didn't have curses - such as on Windows and when Python was built without curses support. No curses can also be emulated by (re)moving .../lib/python2.7/curses/ from the Python installation. It is left as an exercise to figure out exactly what changed in Mercurial that triggered this error.

win32: backout 1a9ebc83a74c This change conflicted with TortoiseHg's use of QFileSystemWatcher. Files which were being monitored (for file-system events) were unable to be reliably updated using util.atomictempfile. Often the update would error out in the middle of the process leaving neither the old or the new file in place. My guess is that _kernel32.CreateFileA() is triggering an exception that is not handled correctly within unlink()

test-check-code-hg: use locate instead of manifest

test-check-code-hg: drop manual check of non-.py scripts

test-check-code-hg: use test-repo check

check-code: look at shebang to identify Python scripts

tests: use locate to find files for pyflakes check Based on a suggestion by Yuya Nishihara

Added signature for changeset 2195ac506c6a

Added tag 3.0 for changeset 2195ac506c6a

revset: directly use __contains__ instead of a lambda We get rid of lambda in a bunch of other place. This is equivalent and much faster. (no new timing as this is the same change as three other changesets)

tests: suppress spurious lchmod error from unzip (issue4088) Because lchmod doesn't exist on Linux, unzip should be built without lchmod support. A few distros get this wrong.

orderedlazyset: directly use __contains__ instead of a lambda We apply the same speedup as in spanset, getting rid of the useless lambda. (No new timing, as this is the very same change)

rebase: empty revset should be a gentle no-op with exit code 1, not an error

largefiles: better handling of log from other working directory (issue4236) When invoked from another directory, the matchers m._cwd will be the absolute path. The code for calculating relative path to .hglf did not consider that and log would fail with weird errors and paths. For now, just don't do any largefile magic when invoked from other directories.

tests: add repository check for pyflakes test If this test was run from a tarball with no Mercurial repository, it would fail because 'hg manifest' didn't work.

spanset: directly use __contains__ instead of a lambda Spanset are massively used in revset. First because the initial subset itself is a repo wide spanset. We speed up the __and__ operation by getting rid of a gratuitous lambda call. A more long terms solution would be to: 1. speed up operation between spansets, 2. have a special smartset for `all` revisions. In the mean time, this is a very simple fix that buyback some of the performance regression. Below is performance benchmark for trival `and` operation between two spansets. (Run on an unspecified fairly large repository.) revset tip:0 2.9.2) wall 0.282543 comb 0.280000 user 0.260000 sys 0.020000 (best of 35) before) wall 0.819181 comb 0.820000 user 0.820000 sys 0.000000 (best of 12) after) wall 0.645358 comb 0.650000 user 0.650000 sys 0.000000 (best of 16) Proof of concept implementation of an `all` smartset brings this to 0.10 but it's too invasive for stable.

transaction: fix file descriptor leak for journal.backupfiles The journal.backupfiles descriptor wasn't being closed. This resulted in hgsubversion test runs having a bagillion descriptors open, which crashed on platforms with low open file limits (like OSX).

revset: also inline spanset._contained in __len__ For consistency with what happen in `__contains__`, we inline the range test into `__len__` too.

revset: inline spanset containment check (fix perf regression) Calling a function is super expensive in python. We inline the trivial range comparison to get back to more sensible performance on common revset operation. Benchmark result below: Revision mapping: 0) 3f83fc5cfe71 2.9.2 release 1) bcfd44abad93 current @ 2) This revision revset #0: public() 0) wall 0.010890 comb 0.010000 user 0.010000 sys 0.000000 (best of 201) 1) wall 0.012109 comb 0.010000 user 0.010000 sys 0.000000 (best of 199) 2) wall 0.012211 comb 0.020000 user 0.020000 sys 0.000000 (best of 197) revset #1: :10000 and public() 0) wall 0.007141 comb 0.010000 user 0.010000 sys 0.000000 (best of 361) 1) wall 0.014139 comb 0.010000 user 0.010000 sys 0.000000 (best of 186) 2) wall 0.008334 comb 0.010000 user 0.010000 sys 0.000000 (best of 308) revset #2: draft() 0) wall 0.009610 comb 0.010000 user 0.010000 sys 0.000000 (best of 279) 1) wall 0.010942 comb 0.010000 user 0.010000 sys 0.000000 (best of 243) 2) wall 0.011036 comb 0.010000 user 0.010000 sys 0.000000 (best of 239) revset #3: :10000 and draft() 0) wall 0.006852 comb 0.010000 user 0.010000 sys 0.000000 (best of 383) 1) wall 0.014641 comb 0.010000 user 0.010000 sys 0.000000 (best of 183) 2) wall 0.008314 comb 0.010000 user 0.010000 sys 0.000000 (best of 299) We can see this changeset gains back the regression for `and` operation on spanset. We are still a bit slowerfor the `public()` and `draft()`. Predicates not touched by this changeset.

ancestor: silence multiple ancestor warning outside of merge (issue4234) The current situation is a bit of a layering violation as merge-specific knowledge is pushed down to lower layers and leaks merge assumptions into other code paths. Here, we simply silence the warning with a hack. Both the warning and the hack will probably go away in the near future when bid merge is made the default.

revsetbenchmark: fix error raising We want to display the commands, not all arguments of the function. (The old code actually crash, failing to joining a list of lists.)

revset: fix revision filtering in spanset.contains (regression) The argument is `x` but the variable tested for filtering is `rev`. `rev` happens to be a revset methods, ... never part of the filtered revs. This method is now using `rev` for everything.
