run-tests: fix heredoctest for out-of-tree extensions heredoctest.py directory must be in python path to use heredoctest (>>>) in out-of-tree extension tests like: $ cd ext/tests $ python /some/hg/install/tests/run-tests.py test-ext.t

revset: added cache to lazysets This allows __contains__ to return faster when asked for same value twice.

histedit: shorten new fold message Lots of people, like Mr. Check-Code, insist on using 80-column terminals.

run-tests: unnecessary globs also count as warnings When a glob is unnecessary, now there's a diff output and 'run-tests.py -i' works for accepting the output. On windows, some tests which have "passed" currently (with some info lines printed) will now be reported as "warned". (I recommend to recognize "warned" by buildbot before applying this patch.)

run-tests: report a test as warned when only missing globs On windows, some test reported as failed will now be reported as "warned".

run-tests: add possibility for test-runners to report a "warned" test result A test result is recognized as "warned" when the test runner returns the exit code False. (False is similar to 0, which is reporting a command has run sucessfully.) The only difference in display is that the failure message while running writes "Warning:" instead of "ERROR:". The diff output is the same as when the test fails. Runing "run-tests.py -i" asks to accept the changed result also for tests reported as "warned". When running tests, a "warned" test would look like this: .. --- xxxx\tests\test-something.t +++ xxxx\tests\test-something.t.err @@ -1279,7 +1279,7 @@ $ echo anything $ hg commit -S -m whatever committing subrepository s - committing subrepository s/sbs + committing subrepository s/sbs (glob) warning: something happened committing subrepository t $ echo something Warning: xxxx\tests\test-sOMETHING.t output changed ~.s...s...s.. Reporting a test result as "warned" will be used in following patches.

run-tests: separate exit code when no failed tests but warned ones This can be used by buildbot to set the result "warnings" instead of "failed".

run-tests: introduce 'warned' as test result While running, a test resulting in 'warned' is shown as '~'. Test results with state warned are listed between the skipped and the failed tests. Example: Skipped test-revert-flags.t: missing feature: executable bit Skipped test-inotify-lookup.t: missing feature: inotify extension support Warned test-something.t: output changed Failed test-largefiles.t: output changed Failed test-subrepo.t: output changed # Ran 11 tests, 2 skipped, 1 warned, 2 failed. The test result "warned" will be used in later patches.

run-tests: handle sys.exit in main function

run-tests: remove unnecessary variable initialisation ret is always set before it is used, so remove ret = 0

histedit: clarify description of fold command N and (N-1) didn't add any information to description of fold. More useful is refering to the commit list as it is displayed in editor.

discovery: make "note: unsynced remote changes!" less serious than a warning This situation is not necessarily a problem and do not deserve a warning. It is just some information that can guide the user in understanding what is going on. Making it 'debug' would usually not give the hint when it is relevant so we make it a 'status' message.

discovery: improve "note: unsynced remote changes!" warning This message frequently caused confusion. "unsynced" is not a well established user-facing concept in Mercurial and the message was not very specific or helpful. Instead, show a message like: remote has heads on branch 'default' that are not known locally: 6c0482d977a3 This message will also (when relevant) be shown before aborting on "push creates new remote head". A similar (but actually very different) message was addressed in 6b618aa08b6e.

import: move tryone closure in cmdutil We extract the `tryone` function into the `cmdutil` module. A lot of the command context have to be passed to the utility function, but having and explicit declaration will allow extension to wrap it. This will allows use to make changeset evolution related experiment in dedicated extension. Improving the API of this function is noble goal but outside of the scope of this patches.
