tests: reduce spurious failures when run with generaldelta Quite a few tests fail in noisy but meaningless ways when the test suite is run with generaldelta enabled: ./run-tests.py --extra-config-opt=format.generaldelta=1 This reduces the amount of noise introduced by the debugindex command, the main source of differences. In my environment, when testing with generaldelta enabled, this change reduces the number of completely failing tests from 21 to 8.

histedit: add extension docstring from external README Made a couple of tweaks to try and fit better with the hg docstring style and fix up some ReST errors in the README.

histedit: don't crash if the result of fixing up a fold is empty

histedit: replace hexshort lambda with node.short

revlog: make compress a method This allows an extension to optionally use a new compression type based on the options applied by the repo to the revlog's opener. (decompress doesn't need the same treatment, as it can be replaced using extensions.wrapfunction, and can figure out which compression algorithm is in use based on the first byte of the compressed payload.)

largefiles: batch statlfile requests when pushing a largefiles repo (issue3386) This implements a part of issue 3386. It batches the request for the status of all largefiles in the revisions that are about to be pushed into a single request, instead of doing N separate requests. In a real world test case, this change was verified to save 1,116 round-trips to the server. It only requires a client-side change; it is backwards-compatible with an older version of the server.

obsolete: write obsolete marker inside a transaction Marker are now written as soon as possible but within a transaction. Using a transaction ensure a proper behavior on error and rollback compatibility. Flush logic are not necessary anymore and are dropped from lock release. With this changeset, the obsstore is open, written and closed for every single added marker. This is expected to be highly inefficient and batched write should be implemented "quickly". Another issue is that every flush of the file will invalidate the obsstore filecache and trigger a full re instantiation of the repo.obsstore attribute (including, reading and parsing entry). This is also expected to be highly inefficient and proper filecache operation should be implemented "quickly" too. A side benefit of the filecache issue is that repo.obsstore object is properly invalidated on transaction abortion.

obsolete: append new markers to obsstore file instead of rewriting everything This is the second step toward incremental writing of marker inside a transaction. The obsstore file is now handled append only. Header writing have been extracted from _writemarkers. Because the _writemarkers method have been dropped, the push code directly reuse the serialised content of local repo `listkeys`. This is not very pretty, but this part of the protocol still need major improvement anyway.

obsolete: move obsolete markers read/write logic to obsstore object This is the first step toward incremental writing of obsolete marker within a transaction. For this purpose, obsstore is now given its repo sopener. This make it able to handles read and write to the obsstore file itself. Most IO logic is removed from localrepo and handled by obsstore object directly.

debugobsolete: remove spurious ctx from variable name 'contexts' are objects like the ones described in context.py, not anything that describes a situation.

setup: disable -mno-cygwin if building under mingw32 This gcc option has been deprecated since at least 2009 (gcc 4.4), and it causes compilations to fail entirely with gcc 4.6.x. Upstream distutils bug: http://bugs.python.org/issue12641

graphlog: don't truncate template value at last \n Most uses of templates requires a trailing newline to get vertical output. Graphlog with a template without trailing newline did however not just create horisontal output like other commands would but truncated the output at the last \n. Template values without any \n were ignored completely. Graphlog will now only eat one trailing newline before it lets the flow of the graph add the necessary vertical space.

graphlog: display obsolete changeset as "x" Changeset detected as obsolete will be displayed as "x" instead of 'o': o new rewritten changeset | | x old obsolete changeset |/ | o base This will be useful even when some obsolete changeset will be "hidden" because not all obsolete changeset can be hidden. If an obsolete changeset have non-obsolete descendant we can't simply hide it. And having a clear visual hint that the changeset is obsolete is useful. The main reason to make this minor change right now is to: 1) introduce an officiel user of the `ctx.obsolete()` method that will detect breakage earlier than third party code (mutable, hgview) 2) Do not display any vocabulary related to obsolete. Such vocabulary will require discussion.

obsolete: fix context.obsolete() method - obsstore attribut name changed. - public changeset can't be obsolete

obsolete: fix error message at marker creation precursors content where printed for invalid successor.

help: explain effect of .hgignore on tracked files

hgignore: simply ignore all *.exe's everywhere it's not like we're going to add any exe anywhere ever

tests: ignore pax_global_header in test-subrepo-git.t Failure seen on hgbuildbot 2.4 and 2.5 after 1894dac619de. Hide '../archive_x/s/pax_global_header' with same strange trick as in 5dda6c708138.

tests: remove GNU quoting in test-subrepo-deep-nested-change.t Test failure on non-GNU systems introduced in 1894dac619de.

tests: add '(glob)' for Windows paths in test-subrepo-deep-nested-change.t Test failure was introduced in 1894dac619de.

check-code: verify that 'saved backup bundle to ...' is '(glob)'ed This is the most frequent trivial reason tests fail on Windows.

tests: fix test markup in test-merge-types.t ca5cc2976574 introduced some tests that because of incorrect indentation wasn't run.

test-hgweb-diffs: partially adapt for Windows Since chmod isn't supported on Windows (or vfat), I'm importing a here-doc instead (<<EOF ..). Option --bypass on import of the here-doc is required on Windows (or vfat) to bypass the working directory (see hg help import). Not using --bypass would lose the mode changing bits. I've had to insert a --bypass on the preexisting import call futher down in the test, because importing a patch with --exact and mode changes will fail on Windows (and vfat). As the point of this test is not to test commit, I'm using the import procedure for all platforms unconditionally, that is, I'm intentionally not keeping the original sequence of hg and chmod calls for platforms that support exec either, which saves us having to insert an #if exec ... #else ... #endif.

subrepo: propagate matcher to subrepos when archiving Add a match object to subrepo.archive(). This will allow the -X and -I options to be honored inside subrepos when archiving. They formerly only affect the top level repo.

largefiles: remove a standin check that could never be true

largefiles: fix the directory structure when archiving a subrepo in a subrepo Previously, a repo consisting of main/sub/subsub archived sub and subsub as siblings under main.

largefiles: fix a traceback when archiving a subrepo in a subrepo This regression was introduced in 43fb170a23bd.

help: improve hgweb help The existing help only walked through an example. Now we first explain the basic rules and then show an example. The 'collections' example and description only cause confusion and is removed. Bikeshedded by Patrick Mezard <patrick@mezard.eu>

convert: keep branch switching merges with ancestors (issue3340) When running convert with a filemap, merge parents which are ancestors of other parents are ignored. This is hardly a problem when parents belong to the same branch, but the result could be confusing when named branches are involved. With: -o-a1-a2-a3... <- A \ \ b1-b2-b3...-m- <- B If all b* revisions are discarded, it is useful to preserve 'm' even if it is empty after filtering to record the branch switch. This patch makes filemap preserve "ancestor parents" if there is no "non-ancestor parent" on the same branch than the merge revision. Remarks: - I am not completely convinced by the reasons given above and those detailed by Matt in this thread: http://selenic.com/pipermail/mercurial-devel/2012-May/040627.html The properties we try to preserve are not clearly defined. That said, I know this patch already helped someone on IRC and the tests output look reasonable. - This is a new version of the original "convert: filemap must preserve fast-forward merges" patch. It has exactly the same output for 2 parents merges, the additional complexity is here to handle more than two parents.

revset: add "diff" field to "matching" keyword The new "diff" field lets you use the matching revset keyword to find revisions that apply the same change as the selected revisions. The match must be exact (i.e. same additions, same deletions, same modified lines and same change context, same file renames and copies). Two revisions matching their diff must also match their files. Thus, to match the diff much faster we will always check that the 'files' match first, and only then check that the 'diff' matches as well.

mq: defer command wrapping to extsetup (API) mq wraps all commands that are not in commands.norepo, which is now performed in this second phase of the extensions setup process. This goes against the current best practices on the wiki [1] as far as where command wrapping is performed, but follows it regarding where global options are injected. mq needs to be the first layer called when command dispatching in order to consistently retarget to the patch repo, regardless of the load order of the extensions. This means being the last to wrap the command table. Previously, 'hg <extdiff> --mq' would diff the main repo unless mq was enabled after extdiff.

revset: ensure we are reversing a list (issue3530)

test-keyword: adapt for Windows

tests: don't use dates before epoch in test-keyword.t Timezone offsets of less than a minute is not shown but can cause displayed dates to be before epoch start - and dates before epoch start is not shown correctly on Windows (see also 4d5b12a5517b). These 'negative' dates could be considered undefined behaviour so we don't care and swap the tests values for timestamp and timezone.

tests: make test-convert-bzr.t more stable The test would occasionally fail because datesort don't have sub-second granularity and thus can't sort commits made in the same second. The test is made more stable by adding 1 second of sleep to make sure the bzr commits are done with different timestamps.

casecollision: add tests Add more tests to exercise the case collion detection code

dirstate: add dir/file collision test Add a test exercising collisions in add between files and directories of the same name.

dirstate: factor common update code into _addpath Factor update code common to all callers of _addpath into _addpath. By centralizing the update code here, it provides one place to put updates to new data structures - in a future patch. It also removes a few lines of duplicate code.

test-subrepo-relative-path: partially adapt for Windows

tests: make rm of usercache in test-largefiles.t more robust Recursive removal of a different path could be fatal - better avoid recursive rm completely.

tests: enable test-largefiles.t on Windows MSYS The 'serve' requirement is moved to the sections that really need it. $USERCACHE needs quoting.

test-largefiles: partially adapt for Windows The adaption is partial, because "serve" is not yet officially supported in tests on Windows. The test passes on Windows with an experimental testbed that supports hg serve in tests on Windows - except for some USERCACHE issues. The added (glob)'s are needed because of backslash <-> shlash issues in paths.

tests: make histedit pass on Windows MSYS The command file will now be named with $TESTTMP (with '\') instead of `pwd` (with '/') to avoid wrong path conversions.

tests: make histedit tests more resilient to filesystem variation Better quoting of odd filesystem paths and no dependency to execute bit.

tests: convert histedit tests to .t Mostly a trivial conversion.
