tests: stop direct symbol import of pprint.pprint in tests-minirst

tests: import mercurial modules by name in test-propertycache This is our convention, and silences import-checker.py that would say imports weren't lexically sorted.

tests: remove unused import of mercurial.repoview from test-propertycache I don't see any reason to import it, but if there is a reason, please disregard this and the next patch.

templater: drop deprecated handling of KeyError from changeset_templater It's been superseded by 09cde75e0613 and the previous patch. templater.mapfile is no longer used and removed.

test-commandserver: handle cStringIO.StringIO/io.StringIO divergence

pycompat: add util.stringio to handle py3 divergence util.stringio = cStringIO.StringIO / io.StringIO

pycompat: alias xrange to range in py3

pycompat: fix demand import handling of Queue When demandimport is enabled, simply importing a non existent module does not trigger ImportError, a property access is necessary.

util: use __code__ (available since py2.6)

templater: give better error message for invalid engine type Before, KeyError was caught at changeset_templater._show(), which said "no key named '%s'" as it was intended to catch the KeyError of unknown map key. Instead, we should catch KeyError explicitly for better error indication. For those who don't know what the template engine is (read "everyone"), it is hidden extension feature that allows switching template syntax in map file. See d8c5a7f25a40 for details.

transaction: allow running file generators after finalizers Previously, transaction.close would run the file generators before running the finalizers (see the list below for what is in each). Since file generators contain the bookmarks and the dirstate, this meant we made the dirstate and bookmarks visible to external readers before we actually wrote the commits into the changelog, which could result in missing bookmarks and missing working copy parents (especially on servers with high commit throughput, since pulls might fail to see certain bookmarks in this situation). By moving the changelog writing to be before the bookmark/dirstate writing, we ensure the commits are present before they are referenced. This implementation allows certain file generators to be after the finalizers. We didn't want to move all of the generators, since it's important that things like phases actually run before the finalizers (otherwise you could expose commits as public when they really shouldn't be). For reference, file generators currently consist of: bookmarks, dirstate, and phases. Finalizers currently consist of: changelog, revbranchcache, and fncache.

run-tests: move install.err into test area Without this, sometimes installerrs generated errors about no such file. It also did not work well when you had multiple tests runners running around. It also did not make sense to pollute the repository test directory with the log file.

help: report source of aliases

compact: add color labels to -Tcompact

util: fix doc for datestr() timezone parameter was removed with c3182eeb70ea

date: reallow negative timestamp, fix for Windows buggy gmtime() (issue2513) DVCS are very useful to store various texts (as legislation) written before Unix epoch. Fri, 13 Dec 1901 is a nice gain over Thu, 01 Jan 1970. Revert dd24f3e7ca9e and e1002cf9fe54, fix c208dcd0f709. Add tests.

tests: use /usr/bin/env python for test-status-inprocess.py everyone else uses it, and the next commit will add a rule for it

run-tests: fix broken regular expression The regular expression in use passed tests because the test repo only has single-digit changesets present. When I tried to use this for real today, it broke, because the regular expression would only match a single digit. https://xkcd.com/1171/, or something like that.

test: don't rely on __del__ in test-devel-warnings.t Whatever the future of __del__ in Mercurial is, that devel-warning test is not about testing the automatic transaction rollback and we should explicitly call release. This change make this tests pass with pypy, as pypy try less hard to call __del__ at program exit.

dispatch: split out warning message generation to separate function Allow for patching warning message generation, or for patching out the ui.log / ui.warn behaviour (but still generate the warning message).

check-code: reject import Queue, suggest util.queue class for py3 compat

scmutil: use util.queue/util.empty for py3 compat

pycompat: add empty and queue to handle py3 divergence While the pycompat module will actually handle divergence, please access these properties from the util module: util.queue = Queue.Queue / queue.Queue util.empty = Queue.Empty / queue.Empty

convert: kill dead code gitread is unused with the new commandline-based code.

convert: don't ignore errors from git diff-tree

crecord: check for untracked arguments hg commit tracked untracked -- fails complaining about untracked prior to this commit, hg commit -i tracked untracked -- did not fail This is corrected by calling the refactored localrepo.checkcommitpatterns

localrepo: drop force check from checkcommitpatterns It was retained to make the code movement clearer

localrepo: refactor commit argument check as checkcommitpatterns

run-tests: handle empty tests

docchecker: try to reject single quotes

docchecker: report context line at most once

tests: splitting test-gendoc.t into per file tests Localizers can now run test-gendoc-$LOCALE.t instead of test-gendoc.t. After this change, test-gendoc.t only checks whether there is *some* localization for the expected set of languages and no others. Whenever a locale i18n/$LOCALE.po is added, someone needs to add test-gendoc-$LOCALE.t

hghave: add cvsnt cvsnt is a maintained commercial fork of cvs https://en.wikipedia.org/wiki/CVSNT It is possible to build a version of it from sources (github), it requires libpcre and libltdl (libtool). We already have a test that relates to cvsnt: test-convert-cvsnt-mergepoints.t cvsnt installs: cvs, cvslockd, cvsnt, cvsscript I think we should definitely have a check for cvsnt because it makes the version checks for cvs make a lot more sense. When I use the version I built, cvs --version says: """ Concurrent Versions System (CVSNT) 2.5.05 (Gan) Build 3744 (Suite) (client/server) CVSNT 2.5.05 (Apr 4 2016) Copyright (c) 2008 March Hare Software Ltd. see http://www.march-hare.com/cvspro CVS Copyright (c) 1989-2001 Brian Berliner, david d `zoo' zuhn, Jeff Polk, and other authors CVSNT Copyright (c) 1999-2008 Tony Hoyle and others see http://www.cvsnt.org Commercial support and training provided by March Hare Software Ltd. see http://www.march-hare.com/cvspro CVSNT may be copied only under the terms of the GNU General Public License v2, a copy of which can be found with the CVS distribution.

commands: allow debugobsolete to delete arbitrary obsmarkers Sample usage is: '$ hg debugobsolete --delete 0 5' This is a debug feature that will help people working on evolution and obsolescense.

commands: disallow 'hg debugobsolete --index --rev <smth>' A bug in the original --index implementation. The goal of --index is to allow unique obsmarker identification that would be consistent between invocations of this command in the unchanged repo. Further goal is to use this index to delete arbitrary obsmarkers. So calling --index together with --rev would cause obsmarker indices to be different than just calling --index. This is not desired and current pattern for getting the index of an interesting obsmarker is: `$ hg debugobsolete --index | grep <interesting hash>`. It would clearly be better if we could somehow compute a hash of an obsmarker and use it to identify the one we want to delete, but it seems a bit too heavy for our current goals, so we can do this later if we want.

mercurial: add editorconfig Editorconfig (http://editorconfig.org/) is a file format helping define coding styles like spaces, tabs etc. It supports a wide range of editors. Some well- known projects like ruby and zsh are using it already. This patch adds a simple .editorconfig, making it clear we use 8-char tabs in C code, 4-char spaces in Python code, and we don't keep trailing spaces.

parsers: fix istat macro to work with single line if statement

pypy: fix setdiscovery test This test relies on the exact details of random.sample given the seed. Things work a bit differently under pypy, make the test less specific.

chg: wrap line at 80 chars This is a style fix. I was using tabstop=4 for some early patches, although I realized we use tabstop=8 later but these early style issues remains. Let's fix them.

chg: replace abortmsg showing errno with abortmsgerrno Since we have abortmsgerrno now, use it to show human friendly error messages across platforms.

chg: add util function abortmsgerrno to print error with errno It's common to abortmsg with the errno information. Let's make a utility function for it.

chg: use color in debug/error messages conditionally Before this patch, chg always uses color in its debugmsg and abortmsg and there is no way to turn it off. This patch adds a global flag to control whether chg should use color or not and only enables it when stderr is a tty and HGPLAIN is not set.

revset: force ascending order for baseset initialized from a set It is possible to initialize a baseset directly from a set object. However, in this case the iteration order was inherited from the set. Set have undefined iteration order (especially cpython and pypy will have different one) so we should not rely on it anywhere. Therefor we declare the baseset "ascending" to enforce a consistent iteration order. The sorting is done lazily by the baseset class and should have no performance impact when it does not matter. This makes test-revset.t pass with pypy.

revset: stabilize repr of baseset initialized with a set Cpython and pypy have different way to build and order set, so the result of list(myset) is different. We work around this by using the sorted version of the data when displaying a list. This get pypy closer to pass test-revset.t.

dispatch: factor out command failure handling into a function Moving the warning generation to a function allows for wrapping and alternative error handling.

pypy: fix overeager pattern matching on mpatchError Pypy have difference in error reporting.

mpatch: unify mpatchError (issue5182) The pure version was mpatch was throwing struct.error or ValueError for errors, whereas the C version was throwing an "mpatch.mpatchError". Introducing an mpatch.mpatchError into pure and using it consistently is fairly easy, but the actual form for it is mercurial.mpatch.mpatchError, so with this commit, we change the C implementation to match the naming convention too.

check-code: reject sed ... \\n This would have caught 142891ab6e89 (fixed by a5a13eeffc59) if repcomment didn't make the content of the perl code opaque to the check.

hideablerevs: expand docstring to warn about possible traps Sean Farley just wasted multiple hours trying to figure out why his code was crashing. We update the docstring to make the constraint clearer.

hghave: replace relative import of docutils.core

tests: make tinyproxy.py not import sys.argv by name

tests: alias ui as uimod in test-walkrepo

tests: alias ui as uimod in test-ui-config

tests: alias ui as uimod in test-context

tests: alias ui as uimod in test-ancestor

tests: sort import lines in tinyproxy.py

tests: sort import lines in failfilemerge.py

tests: sort import lines in dumbhttp.py This series is an attempt to enable import-checker.py for tests/**.py, but it turned out not easy. Since many tests have been ported to absolute_import without the coverage, import-checker.py reports a lot of errors right now. Should we enable import-checker.py without fixing all of them so that we won't get more errors?

chgserver: change random state after fork Before this patch, extensions expecting a different random state per command will break since the chg request handler will inherit a same random state from the parent daemon process. This patch addresses the issue by calling random.seed() after fork.

chg: make connect debug message less repetitive Before this patch, "connect to" debug message is printed repeatedly because a previous patch changed how the chg client decides the server is ready to be connected. This patch revises the places we print connect debug messages so they are less repetitive without losing useful information.

chgserver: use relative path at socket.bind Before this patch, if the server address is long, the server will fail to listen and throw the error: socket.error: AF_UNIX path too long It is because AF_UNIX path usually has a very short length limit (107 chars on common platforms, see sys/un.h). This patch addresses the issue by using relative path instead. Therefore the directory length does not matter. It helps run tests with chg using a long $TMPDIR.

chgserver: move args copying logic to the correct place A previous patch moved it to an incorrect place. Since dispatch._earlygetopt has side effects on args, we need to move it to the place before _earlygetopt.

hghave: update cvs112 description Classic cvs stopped at 1.11. There was a beta version 1.12 that never had a final release. CVS NT is a fork which starts with versions numbered 2.0+. We should have an hg have cvsnt, but to test that requires getting cvsnt, and it's commercial / its older source versions are hard to find.
