util: fix sortdict.update() to call __setitem__() on PyPy (issue5639) It appears that overriding __setitem__() doesn't work as documented on PyPy. Let's patch it as before bd0fd3ff9916. https://docs.python.org/2/library/collections.html#ordereddict-examples-and-recipes The issue was ui.configitems() wasn't ordered correctly, so the pull command was wrapped in different order.

test-revlog-raw: close file handles explicitly (issue5644)

tests: clear __pycache__ for PyPy compatibility (issue5638) (issue5642)

test-extension: glob module name in error message for PyPy

rebase: sort collapsed revisions in commit message (issue5643) This fixes the test instability.

i18n: use actual filename, in which function is defined, for hg.pot Before this patch, source filename for msgid in hg.pot file becomes incorrect, if a function is defined in file A, but detected in dict in file B, For example, almost all debug* commands are defined in debugcommands.py, but hggettext detects them in "table" of commands.py. Therefore, docstring fragments of debug* commands are marked as "defined in commands.py" in hg.pot file. This is serious problem for translation, because the cost to find out original location of texts increases very much.

ui: enable pager always for explicit --pager=on (issue5580) Before this patch, explicit --pager=on is unintentionally ignored by any disabling factor, even if priority of it is less than --pager=on (e.g. "[ui] paginate = off").

rebase: use one dirstateguard for when using rebase.singletransaction This was previously landed as 2519994d25ca but backed out in b63351f6a2 because it broke hooks mid-rebase and caused conflict resolution data loss in the event of unexpected exceptions. This new version adds the behavior back but behind a config flag, since the performance improvement is notable in large repositories. The old commit message was: Recently we switched rebases to run the entire rebase inside a single transaction, which dramatically improved the speed of rebases in repos with large working copies. Let's also move the dirstate into a single dirstateguard to get the same benefits. This let's us avoid serializing the dirstate after each commit. In a large repo, rebasing 27 commits is sped up by about 20%. I believe the test changes are because us touching the dirstate gave the transaction something to actually rollback.

README: make paragraphs before example code end with "::" for reST syntax After this patch, README as reST text can be rendered into HTML more appropriately. This is useful for hosting servers, which render README file as a part of index HTML of its directory (for example, Bitbucket).

commit: don't let failed commit with --addremove update dirstate (issue5645) Differential Revision: https://phab.mercurial-scm.org/D204

tests: demonstrate that failed "hg ci -A" updates dirstate (issue5645) Differential Revision: https://phab.mercurial-scm.org/D203

tests: fix test-flagprocessor.t flakiness The test for duplicate flag processors depended on the timestamps being set in the dirstate to work. If the time between the the previous failed commit (which would set the timestamp, due to bug 5645) and the attempted commit with the duplicate flag processors was small enough, it would fail. The failure was caused by a call to commands.status() early in the commit process. If the dirstate did not have the timestamp set, it would need to fetch the file content to compare with. Since two flag processors had been registered, it would attempted to base64 decode the contents twice, which would of course fail. This patch adds a "hg debugrebuilddirstate" to make it deterministic and also replaces the test case's "hg commit" by simply "hg status", since that will trigger reading of the contents and thereby use of the flag processors as noted above. Differential Revision: https://phab.mercurial-scm.org/D202

tests: clarify that duplicate flag processors is not an error The flag processors test for duplicate processors for a single flag was misleading because the file from the previous test case caused it to fail (making the "echo 'this should fail' > file" part irrelevant). Let's remove the leftover from the previous test case to make it clear that duplicate flag processors results only in a warning. Note that duplicate flag processors would have resulted in a failure (not just a warning) until ea1c2eb7abd3 (extensions: catch uisetup and extsetup failures and don't let them break hg, 2017-06-06). I remember expressing my concern about ending up with half-loaded extensions. It would be pretty unfortunate to have double-encoded revlog content enter a repo, so maybe we should reconsider?

tests: avoid unexpected result at invocation of *.py file on Windows Invocation of "diff tool.py" in test-extdiff.t tests whether shellquote() is applied on specified command as expected. But direct invocation of "*.py" file might cause unexpected result on Windows according to suffix binding. For example, starting IDE, showing dialog to choose program to be used, and so on. In such case, running test-extdiff.t is easily timed out. This patch uses intermediate *.bat file on Windows, to avoid such unexpected result. Naming that intermediate file as "diff tool.bat" is enough to test applying shellquote().

tests: use pdiff instead of diff for portability "diff" command might cause redundant message, "No differences encountered" on Solaris for example. But suppressing option like "-q" isn't portable, because POSIX specification doesn't define it. pdiff script was introduced by b59ef0c21405 to stabilize output of standard diff command on each platforms.

tests: make pdiff return appropriate exit code at comparison of files Before this patch, pdiff script returns 0, even if diff is detected. This issue doesn't cause failure of tests using it, if it is invoked via extdiff extension, because extdiff itself examines changes between specified revisions and decides exit code. BTW, this patch ignores recursive comparison case, because: - there is no portable way for current while-read based implementation to return 1 at detecting changes - it isn't yet needed to replace direct "diff -r" invocation by pdiff for portability

merge with stable

tests: make test-profile.t pass if statprof didn't collect samples We had the first 3 tests in test-profile.t fail because the output didn't match. I have not yet confirmed that this was because no samples were collected, but we shouldn't require samples to be collected for the test to pass either way.

pypy: fix failing test-devel-warnings.t with Pypy5.6.0 In Pypy 5.6.0, traceback exception classes are not displayed with their full qualified name. Instead of displaying mercurial.error.ProgrammingError, Pypy displays ProgrammingError. Update the test to support both version.

pypy: fix failing test files with Pypy5.6.0 Pypy 5.6.0 saves cached bytecode files in __pycache__ directory, clean them in tests to fix loading old test extensions code. Doing so should also helps for Python3.x migration.

commitextras: make sure keys are not empty Thanks to Yuya for catching this.

make: add new directory 'hgdemandimport' to cleanbutpackages rule This fixes the build process for ppa (at least in my simple check). Perhaps we should loop through all directory that aren't 'packages'?

statichttprepo: implement wlock() (issue5613) statichttprepo inherits from localrepository. In doing so, it obtains default implementations of various methods, like wlock(). Before this change, tags cache writing would call repo.wlock(). This failed on statichttprepo due to localrepository's wlock() looking for an instance attribute that doesn't exist on statichttprepo (statichttprepo doesn't call localrepository.__init__). We /could/ define missing attributes until the base wlock() works. However, a statichttprepo is remote and read-only and can't be locked. The class already has a lock() that short circuits. So it makes sense to implement a short-circuited wlock() as well. That is what this patch does. LockError is expected to be raised when locking fails. The constructor takes a number of arguments that are local repository centric. Rather than rework LockError to not require them (which would not be appropriate for stable), this commit populates dummy values. I don't believe they'll ever be seen by the user, as lock failures on static http repos should be limited to well-defined (and tested) scenarios. We can and should revisit the LockError type to improve this.

test: add tests for branches and tags with static http repo (issue5613) Mercurial currently fails to clone by revision on static http repos with tags. The added tests demonstrate this.

commitextras: make sure keys contains ascii letters, numbers, '_' and '-' only

phabricator: convert unicode to binary when writing patches This is a quick fix to make `hg phabread D189` work.

osx: wire up genosxversion script The only version strings that are changed are the ones baked into the .pkg - hg's self-reported version string doesn't change, so users will still see our mostly-pip-compatible version strings. For reference, the part of our versioning setup that's not PEP440 compatible is the RC releases - those should be .rc0 insted of -rc. It's too late to change that for the 4.3 cycle, so I'll worry about fixing that during the 4.4 cycle.

osx: new script for generating OS X package versions If you're shipping prerelease or rc packages using Munki, you'll eventually discover that Munki's version comparison logic is not as good as pip's. In theory we should be able to fix Munki, but it seems entirely reasonable to produce version strings that sort reasonably under these conditions. Since the requried logic not brief, add a new script and some tests of that logic. A followup change will wire this into the Makefile.

tests: update mac packaging test expectations Some more files are included these days.

tests: add support in run-tests.py for an environment variable to stop color I don't like the color output, so this gives me a way to easily never see it while still having pygments on my machine.

setup: fix mistake that prevented Python 3 from being excluded My intent was to only allow Python 3 if the right environment variable is set (for when people want to use `pip install .` on hg locally). This fixes the bug in my previous change. I verified that `python3.6 run-tests.py` still passes the tests that passed before, and that all tests pass on 2.7 (including our virtualenv-using installation test).

rebase: move bookmark to destination for commits becoming empty (issue5627) When rebasing a changeset X and that changeset becomes empty, we should move the bookmark on X to rebase destination. This is a regression caused by the scmutil.cleanupnodes refactoring for rebase. The `adjustdest` function calculates the destination of bookmark movement. It was back-ported from https://phab.mercurial-scm.org/D21. It might be slightly more powerful than the minimal requirement to solve this issue. For example, it's impossible for a merge changeset to become empty while any of its ancestors does not become empty, but the code could handle that case. Since the code is reasonably short and clean, and helps the upcoming D21 series, I'd like to check-in `adjustdest` now. Thanks Martin von Zweigbergk for spotting corner cases (-k and descendant with bookmarks) in this area!

setup: drop use of set literal so parsable on Python 2.6 Otherwise friendly error wouldn't be displayed.

setup: add extra logic to try and recommend a new pip on bad Python Modern pip can detect supported Python versions (which we now declare), and pull down a reasonable release. This trick was suggested in http://bit.ly/pycon2017-build-bridges, and seems like a good defensive maneuver so that when we want to move to Python 3 it's less risky for existing users. This moves the version-check logic after defining our printf function so we can print more informative messages.

setup: explicitly declare supported Python versions I think we should probably backport this to 4.2 as well, and do one more release there that explicitly declares 2.6 support. That way anyone stuck on Python 2.6 will end up getting the right hg if they use a modern pip to install. Users can still use `python setup.py` incantations to attempt installing Mercurial on unsupported Pythons, including 3.5 and 3.6. A followup change will switch to only doing our own Python-version-check logic if we're not being installed by a reasonable pip.

contrib: remove one test from the python 3 whitelist 439b4d005b4a introduced a use of 'hg revert --no-backup' which is currently broken. Rather than try and do a fix on the (complicated) revert code during the freeze, let's just give up on this test under Python 3 until later. Once we do fix things, the test ratchet script will re-enable it.

test-https: properly conditionalize Windows vs non-Windows output There's a bug in the (feature !) annotation, and this needs to be resolved before fixing it. Once fixed, the glob '*/missing' will match the output '/missing' on non-Windows platforms, consuming the output line and leaving nothing for the no-windows required line. I probably should have made (foo !) match only the 'foo' feature, and be ignored otherwise instead of optional. (re) didn't work here, because the parenthesis need to be escaped too.

releasenotes: add custom admonitions support for release notes By default, the extension has default sections like fix, feature, perf etc.. This patch allow user to add support for custom admonition. In order to add a custom admonition, one needs to have a .hgreleasenotes file inside the repository. All the custom directive with name specified under the tag [sections] will be usable by the extension. One important thing to keep in mind is if there exists any custom admonitions with same key as default then they will override the default ones.

check-config: mention the file and line of the error I used this to more quickly track down a failing test-check-config.t issue in another repo. I thought it might be useful more generally, so I'm sending it out in case others think it's a worthwhile change.

rebase: add config to move rebase into a single transaction This was previously landed as cf8ad0e6c0e4 but backed out in a5abaa81fa because it broke hook mid rebase and caused conflict resolution data loss in the event of unexpected exceptions. This new version adds the behavior back but behind a config flag, since the performance improvement is notable in large repositories. The next patch adds a test covering this config. The old commit message was: Previously, rebasing would open several transaction over the course of rebasing several commits. Opening a transaction can have notable overhead (like copying the dirstate) which can add up when rebasing many commits. This patch adds a single large transaction around the actual commit rebase operation, with a catch for intervention which serializes the current state if we need to drop back to the terminal for user intervention. Amazingly, almost all the tests seem to pass. On large repos with large working copies, this can speed up rebasing 7 commits by 25%. I'd expect the percentage to be a bit larger for rebasing even more commits. There are minor test changes because we're rolling back the entire transaction during unexpected exceptions instead of just stopping mid-rebase, so there's no more backup bundle. It also leave an unknown file in the working copy, since our clean up 'hg update' doesn't delete unknown files.
