tests: avoid quoting of commit messages for test portability journal extension uses util.shellquote() to record command line, but result of it depends on runtime platform: double quotation is used on Windows and OpenVMS, but single quotation is used otherwise. test-journal-share.t sometimes specifies commit messages including white space on command line. It makes journal output depend on runtime platform, but commit message itself isn't important in this test case.

tests: use basic format code "%Y" instead of "%s" for test portability On Windows, strftime() doesn't support format code "%s", and it causes "invalid format string" error. https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx test-command-template.t examines not seconds value in UTC, but arithmetic calculation. Therefore, using format code "%Y" instead of "%s" should be reasonable. FYI: - Python standard library reference doesn't list "%s" up in format code list required for "C standard (1989 version)", even though it also mentions that additional format codes are required for "C standard (1999 version)" https://docs.python.org/2.7/library/datetime.html#strftime-and-strptime-behavior - The Open Group Base Specifications Issue 7 (IEEE Std 1003.1-2008, 2016 Edition) doesn't require strftime to support format code "%s" http://pubs.opengroup.org/onlinepubs/9699919799/functions/strftime.html - "man strftime" of (Open/Oracle) Solaris and Mac OS X (= UNIX certified OSs) describes about format code "%s"

tests: add test-commit-interactive-curses.t "require tic" for test portability Standard library of Python on Windows doesn't have curses module.

tests: use "?" to glob both ":" and ";" in output for test portability If environment variable looks like PATH or so (e.g. any of components joined by ":" contains "/"), ":" in it is replaced with ";" by MinGW at spawning Windows native process, to follow path concatenation style of Windows. Therefore, "bundle:../full.hg" is converted into "bundle;..\full.hg" on MinGW. Difference between "/" and "\" is automatically ignored by "(glob)", but difference between ":" and ";" should be globed explicitly.

tests: invoke printenv.py via sh -c for test portability On Windows platform, invoking printenv.py directly via hook is problematic, because: - unless binding between *.py suffix and python runtime, application selector dialog is displayed, and running test is blocked at each printenv.py invocations - it isn't safe to assume binding between *.py suffix and python runtime, because application binding is easily broken For example, installing IDE (VisualStudio with Python Tools, or so) often requires binding between source files and IDE itself. This patch invokes printenv.py via sh -c for test portability. This is a kind of follow up for d19787db6fe0, which eliminated explicit "python" for printenv.py. There are already other 'sh -c "printenv.py"' in *.t files, and this fix should be reasonable. This changes were confirmed in cases below: - without any application binding for *.py suffix - with binding between *.py suffix and VisualStudio This patch also replaces "echo + redirection" style with "heredoc" style, because: - hook command line is parsed by cmd.exe as shell at first, and - single quotation can't quote arguments on cmd.exe, therefore, - "printenv.py foobar" should be quoted by double quotation, but - nested quoting (or tricky escaping) isn't readable

largefiles: handle that a found standin file doesn't exist when removing it I somehow ended up in a situation where hg crashed on an unlink I introduced in 328545c7d8a1. I don't know how it happened and can't reproduce it. It seems like it only can happen when the file is removed between the time of check in a working directory context walk that finds a standin file, and the time of use when we try to remove it because the corresponding largefile doesn't exist. But better safe than sorry: replace the plain unlink with unlinkpath with ignoremissing=True. That will also remove remaining empty directories, which arguably is more correct.

templater: use unfiltered changelog to calculate shortest() at constant time cl._partialmatch() can be pretty slow if hidden revisions are involved. This patch cancels the slowdown introduced by the previous patch by using an unfiltered changelog, which means shortest(node) isn't always the shortest. The result isn't perfect, but seems okay as long as shortest(node) is short enough to type and can be used as an identifier. (with hidden revisions) % hg log -R hg-committed -r0:20000 -T '{node|shortest}\n' --time > /dev/null (.^^) time: real 1.530 secs (user 1.480+0.000 sys 0.040+0.000) (.^) time: real 43.080 secs (user 43.060+0.000 sys 0.030+0.000) (.) time: real 1.680 secs (user 1.650+0.000 sys 0.020+0.000)

templater: do not use index.partialmatch() directly to calculate shortest() cl.index.partialmatch() isn't a drop-in replacement for cl._partialmatch(). It has no knowledge about hidden revisions, and it raises ValueError if a node shorter than 4 chars is given. Instead, use index.partialmatch() through cl._partialmatch(), which has no such problems and gives the identical result with/without --pure. The test output was sampled with --pure without this patch, which shows the most correct result. However, we'll need to switch to using an unfiltered changelog because _partialmatch() of a filtered changelog can be an order of magnitude slower. (with hidden revisions) % hg log -R hg-committed -r0:20000 -T '{node|shortest}\n' --time > /dev/null (.^) time: real 1.530 secs (user 1.480+0.000 sys 0.040+0.000) (.) time: real 43.080 secs (user 43.060+0.000 sys 0.030+0.000)

tests: run "cwd was removed" test only if cwd can actually be removed On some platforms, cwd can't be removed. In which case, util.unlinkpath() continues with no error since the failure of directory removal isn't critical. So it doesn't make sense to run the test added by 90a6c18a7c1d on those platforms. OTOH, we need to run the test in test-rebase-scenario-global.t since the repository is referenced after that.

merge: avoid superfluous filemerges when grafting through renames (issue5407) This is a fix for a regression introduced by the patches for issue4028. The test changes are due to us doing fewer _checkcopies searches now, which makes some test outputs revert to the pre-issue4028 behavior. That issue itself remains fixed, we only skip copy tracing for files where it isn't relevant. As a nice side effect, this makes copy detection much faster when tracing backwards through lots of renames.

sslutil: guard against broken certifi installations (issue5406) Certifi is currently incompatible with py2exe; the Python code for certifi gets included in library.zip, but not the cacert.pem file - and even if it were included, SSLContext can't load a cacert.pem file from library.zip. This currently makes it impossible to build a standalone Windows version of Mercurial. Guard against this, and possibly other situations where a module with the name "certifi" exists, but is not usable.

revset: don't cache abstractsmartset min/max invocations infinitely There was a "leak", apparently introduced in ab66c1dee405. When running: hg = hglib.open('repo') while True: hg.log("max(branch('default'))") all filteredset instances from branch() would be cached indefinitely by the @util.cachefunc annotation on the max() implementation. util.cachefunc seems dangerous as method decorator and is barely used elsewhere in the code base. Instead, just open code caching by having the min/max methods replace themselves with a plain lambda returning the result.

dirstate: fix debug.dirstate.delaywrite to use the new "now" after sleeping It seems like the a regression has sneaked into debug.dirstate.delaywrite in 6c6b48aca328. It would sleep until no files were modified "now" any more, but when writing the dirstate it would use the old "now" and still mark files as 'unset' instead of recording the timestamp that would make the file show up as clean instead of unknown. Instead of getting a new "now" from the file system, we trust the computed end time as the new "now" and thus cause the actual modification time to be writiten to the dirstate. debug.dirstate.delaywrite is undocumented and only used in test-largefiles-update.t . All tests seems to work fine for me without debug.dirstate.delaywrite . Perhaps because it not really worked as intended without the fix in this patch, and code and tests thus have evolved to do fine without it? It could thus perhaps make sense to drop usage of this setting in the tests. That could speed the test up a bit. This functionality (or something very similar) can however apparently be very convenient in setups where checking dirty-ness is expensive - such as when using large files and have slow file filesystems or are CPU constrained. Now it works and we can try it. (But ideally, for the largefile use case, it should probably only delay lfdirstate writes - not ordinary dirstate.)

tests: fix test-casefolding.t The message had changed, but the test was not updated. This test does not run on Linux, but failed on my Mac.
