rebase: fix 'rebase onto %d starting from %s' - show root instead of list repr The debug statement is already in a 'for root in roots' so it was probably the intention to show root instead of roots. Do that.

log: describe graph symbols in the help I wondered what 'x' meant and didn't find it described anywhere.

tests: backout a82de9dc4f77, debugstacktrace is now stable, drop workaround

util: debugstacktrace, flush before and after writing Close another stream (default stdout, which often is buffered) before writing to the primary stream (default stderr, which often is unbuffered). The primary stream is also flushed after writing (in case it is buffered). This fixes non-deterministic output order, especially on windows.

run-tests.py: work when --with-hg is set to system hg Previously we'd always assume that --with-hg is a script in a user directory, and would write out a 'python' symlink to the same location. That didn't work if --with-hg was set to a system installation of hg, e.g. /usr/bin/hg. Introduce a TMPBINDIR directory which is used to write out the python symlink.

revset: added cached generated list on generatorset This allows to iterate the generatorset more than once.

templater: shorten pure integers Originally, the addition of the 'shorten' template function in 9c6b86dd2ed2 would not consider pure integers for shortening. This patch considers two simple cases: when the integer starts with zero (which is parsed by Mercurial as a hash first) and when the integer is larger than the tip (obviously not a rev).

revset: fixed bug where log -f was taking too long to return

revset: added generatorset class with cached __contains__ method

pathencode: eliminate signed integer warnings Compiling mercurial with the Sun Studio compiler gives seven copies of the following warning on pathencode.c: line 533: warning: initializer will be sign-extended: -1 Using explicit unsigned literals silences it.

revset: changed last implementation to use lazy classes Instead of using getitem just reverse the revision list and get the first 'lim' elements. With classes like spanset which are easily reversible this will work faster. Performance Benchmarking: $ time hg log -qr "last(all())" ... real 0m0.569s user 0m0.447s sys 0m0.122s $ time ./hg log -qr "last(all())" ... real 0m0.215s user 0m0.150s sys 0m0.063s

help: remove last occurrences of ".. note::" without two newlines When we add two newlines after ".. note::" translators will not see this entry. And all versions of docutils interpret this paragraph correctly (details in de16c673455b).

help: add ifcontains, revset, and shortest to template help Adds help information to the template help doc. Mentions ifcontains, revset, shortest, and current in bookmarks.

verify: do not prevent verify repository containing hidden changesets Since a959f7167077, repo.cancopy() cannot be used to check if the repo is a bundlerepository. repo.url() should always have "scheme:", so it isn't necessary to parse by util.url().

hgweb: make sure sys module is loaded prior to reload hack If sys is still a demandmod, reload(sys) fails with "TypeError: reload() argument must be module".

win32: improve the performance of win32.unlink() over CIFS Emulating POSIX unlink() behavior with os.rename() and os.unlink() is often slow especially over CIFS from Windows clients due to its protocol overhead. This patch changes win32.unlink() to try first an exclusive open with the Win32 delete-on-close flag, and if a sharing violation is detected, to fall back to the original emulation. This patch also removes a test with os.path.isdir() since we expect opening a directory shall fail as os.unlink() would.

revset: changed mfunc and getset to work with old style revset methods Now extensions shouldn't break when adding new revsets.

revset: changed revsets to use spanset Performance Benchmarking: $ hg perfrevset "first(all())" ! wall 0.304936 comb 0.300000 user 0.280000 sys 0.020000 (best of 33) $ ./hg perfrevset "first(all())" ! wall 0.175640 comb 0.180000 user 0.160000 sys 0.020000 (best of 56)

revset: changed spanset to take a repo argument This way, we can have by default the length of the repo as the end argument and less code has to be aware of hidden revisions.

journal: report parsing errors on recover/rollback (issue4172)

rebase: do not try to reactivate deleted divergent bookmark If the currently active bookmark is divergent one, it may be resolved during rebase. Trying to activate it will raise "KeyError: 'W@diverge'".

tests: backout 00f2d29308db pid check

revset: changed spanset implementation to take hidden revisions into account Hidden revisions are now excluded from the spanset. Now this doesn't break for people using changeset evolution.

template: add 'current' to scope during {bookmarks % ...} This adds the keyword 'current' to the template scope when processing a bookmark list. The 'current' keyword resolves to the name of the currently active bookmark in the repo. This allows us to apply special labels to the current bookmark to distinguish it (especially in the case where there are multiple bookmarks on the same commit). Example: "{bookmarks % '{bookmark}{ifeq(bookmark, current, \"*\")} '}" Results in a space separated list of bookmarks where the current bookmark has an asterix.

template: add revset() template function Adds a template function that executes a revset and returns the list of revisions as the result. It has the signature 'revset(query [, args...])'. The args are optional and are applied to the query string using the standard python string.format(args) pattern. This allows things like: '{revset("parents({0})", rev)}' to produce the parents of each individual commit in the log output. If no args are specified, the revset result is cached for the duration of the templater; so it's better to not use args if performance is a concern. By itself, revset() can be used to print commit parents, print the common ancestor of a commit with the main branch, etc. It can be used with the ifcontains() function to do things like '{ifcontains(rev, revset('.'), label(...), ...)}' to color the working copy parent, to color certain branches, to color draft commits, etc.

template: add ifcontains template function Adds a template function with the signature 'ifcontains(item, set, then[, else])'. It can be used to do things like '{ifcontains('.hgignore', file_mods, label(...), ...)}' to color commits that edit the .hgignore file. A future patch will add the revset() function which will combine with ifcontains to allow us to color commits if they are in the revset.

createmarkers: allow to pass metadata for a marker only The `metadata` argument only allow to specify metadata for all new markers. We extension the format of the `relations` argument to support optional metadata argument. The first user of this should be the evolve extension who want to store parent information of pruned changeset in extra (until we make a second version of the format)

obsstore: update create docstring to point to the coder friendly function The `obsstore` class have a `create` method that create new obsolescence marker from node. There is another function in the same module `createmarkers`. This other function is higher level and automatically missing meta data (ultimately calling the first one) We add a new comment in the docstring of `obsstore.create` highlighting that people writing new code probably want to use the top level one.

i18n: check equality of initial indentation between msgid and msgstr Document generation by runrst in "doc" directory may succeed silently, even though initial indentation is different between msgid and msgstr: for example, it may be unexpected or missing indentation. This patch adds the checker to check equality of initial indentation between msgid and msgstr. This checker is categorized as "warning" level, because problem detected by this is not so serious for usual Mercurial usage.

i18n: check equality of tail '::'-ness between msgid and msgstr Document generation by runrst in "doc" directory may succeed silently, even though there is the translated message missing tail '::'. In this case, it uses "<blockquote>" instead of "<pre>" to surround succeeding text block unexpectedly in generated HTML file. This patch adds the checker to check equality of tail '::'-ness between msgid and msgstr. To detect also msgstr unexpectedly ending with '::', this checker doesn't have matching regexp against msgid, and is applied on all msgid/msgstr pairs. This checker is categorized as "warning" level, because problem detected by this is not so serious for usual Mercurial usage.

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.

revset: optimize missing ancestor expressions A missing ancestor expression is any expression of the form (::x - ::y) or equivalent. Such expressions are remarkably common, and so far have involved multiple walks down the DAG, followed by a set difference operation. With this patch, such expressions will be transformed into uses of the fast algorithm at ancestor.missingancestor. For a repository with over 600,000 revisions, perfrevset for '::tip - ::-10000' returns: Before: ! wall 3.999575 comb 4.000000 user 3.910000 sys 0.090000 (best of 3) After: ! wall 0.132423 comb 0.130000 user 0.130000 sys 0.000000 (best of 75)

revset: add an undocumented _missingancestors function This will be used in an upcoming patch to optimize expressions of the form (::x - ::y).

commands.debugrevspec: add an option to print the optimized expression tree This will be used in an upcoming patch to test that the optimizer works.

tests: killdaemons.py for windows distinguishes access violation and terminated To distinguish between access violaition (process belonging to another user) and a terminated process, PROCESS_QUERY_INFORMATION must be enabled. But TerminateProcess still raises error 5 in both cases. Therefore check before if the process has already terminated.

tests: killdaemons.py for checks reason when getting no process handle

tests: killdaemons.py for windows waits for killed process to terminate After kill, wait for the process to terminate. When it does not in time, write a debug message similar as in other os. But no 2nd forceful attempt is done.

tests: kill for windows in killdaemons.py checks return values The return values of the windll calls are checked and when an error is indicated, it is raised. The handle is still closed properly.

pull: make pulled subset a propertycache of the pull object The computation of the subset is simple operation using two useful pull information (1) the set of common changeset before the pull (2) the set of pulled changeset. We move this data into the `pulloperation` object since some phase will need them. And we turn the pulled subset computation behind a property case as multiple pull phase will need it.
