tag: clarify warning about making a tag on a branch head Currently the warning is ambiguous about whether the new tag (possibly specified via --rev) is being added on a branch head or whether the working directory is based on a branch head. Clarify the error message to eliminate this ambiguity.

contrib: check reference to old selenic.com domain Now, all URL in Mercurial source tree should refer mercurial-scm.org domain instead of selenic.com. *.po files are ignored in this patch, because they might contain msgid/msgstr coming from old source files. This ignorance seems safe enough, because such msgstr should be ignored at runtime, because: - msgid corresponded to it should be invalid, or - msgstr itself should be marked as fuzzy at synchronized to recent hg.pot If any additional examination for *.po files is needed in the future, let i18n/check-translation.py achieve such examination. BTW, some binary files (e.g. *.png) are meaningless for checking reference to old domain in this patch, but aren't ignored like as *.po files, because excluding multiple suffixes is difficult for regexp matching.

check-code: discard filtering result of previous check for independence Before this patch, check-code.py applies filtering on the file content, to which filtering of previous check is already applied. This might hide issues, which should be detected by a subsequent check in "checks" list. Fortunately, this problem hasn't appeared, because there is no overlapping of filename matching (examined in the order below). 1. *.py or *.cgi 2. test-* (not *.t suffix) 3. *.c or *.h 4. *.t 5. *.txt 6. *.tmpl For example, adding a test, which wants to examine raw comment text in *.py files, at the end of current "checks" list doesn't work as expected, because a filter for *.py files normalizes comment text in them. Putting such test at the beginning of "checks" list also resolves this problem, but such dependence on the order decreases maintainability of check-code.py itself. This patch discards filtering result of previous check at the beginning of each checks, for independence of each checks.

hghave: fix 'rmcwd' to ensure temporary directory is removed On platforms where cwd can't be removed, it should try rmdir() after chdir to the original cwd.

httppeer: make __del__ access to self.urlopener more safe Some errors could in some cases show unfortunate scary and confusing warnings from the httppeer delstructors: abort: nodename nor servname provided, or not known Exception AttributeError: "'httpspeer' object has no attribute 'urlopener'" in <bound method httpspeer.__del__ of <mercurial.httppeer.httpspeer object at 0x106e1f5d0>> ignored``` To mute that, take 7b15dd9125b3 to the next level and use getattr in __del__.

tests: test preserving execbit changes at amending only on execbit platform

tests: put temporary file outside the working directory for test portability test-largefiles-update.t creates temporary file exec-bit.patch inside the working directory for no-execbit platform specific test, but subsequent tests aren't aware of it. On execbit platform, subsequent tests can run successfully, because exec-bit.patch isn't created. But on no-execbit platform, this temporary file makes subsequent tests show "? exec-bit.patch" at each "hg status".

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.

commands: print security protocol support in debuginstall Over the past week I've had to instruct multiple people to run Python code to query the ssl module to see what TLS protocol support is present. I think it would be useful for `hg debuginstall` to print this info to make it easier to access and debug why Mercurial is complaining about using an insecure TLS 1.0 protocol. Ideally we'd also print the path to the CA cert bundle. But the APIs for querying that in sslutil can emit warnings, making it slightly more difficult to integrate into `hg debuginstall`. That work will have to wait for another day.

manifest: make treemanifestctx store the repo Same as in the last commit, the old treemanifestctx stored a reference to the revlog. If the inmemory revlog became invalid, the ctx now held an old copy and would be incorrect. To fix this, we need the ctx to go through the manifestlog for each access. This is the same pattern that changectx already uses (it stores the repo, and accesses commit data through self._repo.changelog).

manifest: make manifestctx store the repo The old manifestctx stored a reference to the revlog. If the inmemory revlog became invalid, the ctx now held an old copy and would be incorrect. To fix this, we need the ctx to go through the manifestlog for each access. This is the same pattern that changectx already uses (it stores the repo, and accesses commit data through self._repo.changelog).

manifest: make manifestlog a storecache The old @property on manifestlog was broken. It meant that we would always recreate the manifestlog instance, which meant the cache was never hit. Since we'll eventually remove repo.manifest and make manifestlog the only property, let's go ahead and make manifestlog the @storecache property, have manifestlog own the manifest instance, and have repo.manifest refer to it via manifestlog. This means all accesses go through repo.manifestlog, which is now invalidated correctly.

manifest: move manifest creation to a helper function A future patch will be moving manifest creation to be inside manifestlog as part of improving our cache guarantees. bundlerepo and unionrepo currently rely on being able to hook into manifest creation, so let's temporarily move the actual manifest creation to a helper function for them to intercept. In the future manifest.manifest() will disappear entirely and this can disappear.
