largefiles: inline _updatelfile, prepare for further refactorings

largefiles: cache largefiles for update, also without printmessage

largefiles: cleanup of printmessage handling - the printed flag was redundant

test-module-imports: skip on Python < 2.6, since ast is new in 2.6

Merge with stable.

convert: fix svn crash when svn.ra.get_log calls back with orig_paths=None get_log started calling back with orig_paths=None on Fedora 20 with subversion-1.8.3. That broke test-convert-svn-source.t . There used to be some handling of that situation until e8f4e40f285a apparently broke it. This patch restores what seems to be the most obvious handling of the situation.

share: fix unshare calling wrong repo.__init__() method When running the unshare command, if there's other code that tries to use the repo after the command is finished, it'll end up with a ui object for repo.unfiltered(). This change fixes an erroneous call to repo.__init__() that could be on the repoview proxy class--now it's always done on the unfiltered repo.

statichttprepo.httprangeheader: implement readlines bookmarks.readcurrent() requires readlines() on file objects returned from repo.vfs. It isn't used right now but will be in upcoming patches.

statichttprepo: pass in True to splitlines, not 1 splitlines actually takes a boolean.

mq: don't add '* * *' separators when there is no commit message

bisect: avoid confusing use of variables with same names in nested local scopes

discovery: make note messages for new heads more readable

discovery: tweak error message for multiple branch heads

test-obsolete-checkheads.t: remove todo comment that was fixed in be0fcbb1c92f

convert: readability and test of rpairs function

tests: make doctest test runner less verbose

tests: python hash seed is only relevant after failures - otherwise keep quiet

scmutil.filecache: support watching over multiple files

scmutil: introduce a filecacheentry that can watch multiple paths

scmutil: rename filecacheentry to filecachesubentry Upcoming patches will allow the file cache to watch over multiple files, and call the decorated function again if any of the files change. The particular use case for this is the bookmark store, which needs to be invalidated if either .hg/bookmarks or .hg/bookmarks.current changes. (This doesn't currently happen, which is a bug. This bug will also be fixed in upcoming patches.)

scmutil.filecacheentry: make stat argument to constructor mandatory There's no real upside to making stat optional -- this constructor has just two callers.

test-filecache.py: add markers to the output for each event Previously it was possible that a different, incorrect set of events might print out 'creating' the same number of times.

test-filecache.py: make setbeforeget test clearer '0' and 'None' as outputs tripped me up. Make the distinction between values set externally and values computed by calling the decorated function clearer.

test-module-imports.t: new test to use the import cycle detector

import-checker: try a little harder to show fewer cycles This makes sure that all cycles begin with the lexicographically first module, so that we're less likely to show overlapping cycles in the final analysis.

import-checker: ignore nested imports

contrib: add an import checker This checks for cycles in the module graph and verifies that imports of stdlib modules are not on the same line as relative imports of mercurial modules.

makememctx: move from patch to context to break import cycle

cleanup: move stdlib imports to their own import statement There are a few warnings still produced by my import checker, but those are false positives produced by modules that share a name with stdlib modules.

pathutil: tease out a new library to break an import cycle from canonpath use

subsettable: move from repoview to branchmap, the only place it's used This is a step towards breaking an import cycle between revset and repoview. Import cycles happened to work in Python 2 with implicit relative imports, but breaks on Python 3 when we start using explicit relative imports via 2to3 rewrite rules.

obsolete: add __eq__ and __hash__ to marker to make set() deduplication work

obsolete: do not accept duplicated marker during exchange Before this patch, duplicated obsolescence markers could slip into an obstore if the bookmark was unknown locally and duplicated in the incoming obsolescence stream. Existing duplicate markers will not be automatically removed but they'll stop propagating. Having a few duplicated markers is harmless and people have been warned evolution is <blink>experimental</blink> anyway.

Merge with stable.

obsolete: stop doing membership test on list According to the Surgeon General, computer should not use list for membership testing because of the risk of being slow.

bookmarks: rewrite pushing bookmarks in "localrepository.push()" by "compare()" This patch adds "updateremote()", which uses "compare()" to compare bookmarks between the local and the remote repositories, to replace pushing local bookmarks in "localrepository.push()".

bookmarks: rewrite pushing local bookmarks in "commands.push()" by "compare()" This patch adds "pushtoremote()", which uses "compare()" to compare bookmarks between the local and the remote repositories, to replace pushing local bookmarks in "commands.push()".

bookmarks: rewrite "updatefromremote()" by "compare()" To update entries in bmstore "localmarks", this patch uses "bin(changesetid)" instead of "repo[changesetid].node()" used in original "updatefromremote()" implementation, because the former is cheaper than the latter.

bookmarks: add function to centralize the logic to compare bookmarks This patch adds "compare()" function to centralize the logic to compare bookmarks between two repositories.

hgweb: use semantically suitable filelog.revs in filelog The functions are equivalent in behaviour, so no behavior change.

hgweb: always compute all entries and latestentry in filelog This is the same thing which was done for changelog earlier, and it doesn't affect performance at all. This change will make it possible to get the first entry of the next page easily without computing the list twice.

hgweb: remove unused argument of entries function in filelog This doesn't change the behavior as the argument wasn't used anyway.

transplant: use peer of source repository as "remote" for "repo.pull()" Before this patch, transplant with "--merge" option fails with traceback unexpectedly, if it causes pull from the source repository on the local host. "discovery.findcommonincoming()" invokes "capable()" method on the object given from "localrepository.pull()", but it is "localrepository" object in this case and doesn't have such method. This patch uses peer object of source repository as "remote" argument for "localrepository.pull()" invocation like other invocations of it in transplant.py.

run-tests: remove files that we potentially create outside of $TMPDIR

run-tests: remove code that creates a dummy 'diffstat' This was introduced in fb1d7a42663c for an old test that is no longer the same.

template: change extras to use showlist rather than manual templ call. This enables start_extras and end_extras in template maps.

help: adding example 'extras' printing to 'hg help templates'

help: document about {extras} template keyword This adds text about the "extras" template keyword, similar to that proposed by Yuya Nishihara previously.

check-code: document last ignore regexp For easier remembering to delete when it is not needed anymore.

check-code: drop unneeded ignore patterns The exceptions seem to have disappeared.

merge with stable

merge with i18n

contrib: add editmerge script for editor conflict prompts Adds a script that opens the editor to the conflict as part of the merge process. This way you can fix the merge during the rebase instead of having to pause the rebase, resolve --mark, rebase --continue. Only works on unix.

strip: fix last unprotected mq reference (issue4097)

tests: skip tests that require not having root (issue4089) This adds a new root hghave to test against. Almost all of these are a subset of unix-permissions, but that is also used for checking exec bit handling.

make: restrict recursion in make clean

scmutil: skip checks in "casecollisionauditor" if filename is already checked Before this patch, almost all of check code in "casecollisionauditor.__call__()" is executed, even if specified filename is already checked, because "f in self._newfiles" is examined lastly. In addition to it, adding "fl" to "self._loweredfiles" and "f" to "self._newfiles" are also redundant in such case. This patch checks "f in self._newfiles" first, and returns immediately to avoid execution of check code for efficiency.

check-code: prepend warning prefix only once, but for each warning The code adding the prefix is now run once per pattern. It was run once per file (after the change 3e1e4a8aec1e). Demonstrate that it is working now by extending the test. Raise two different warnings, one of them twice.

hgweb, i18n: do not translate search mode description The search mode description can't be translated by itself, since it's displayed as part of a template phrase (the "Assuming ..." / "Use ... instead" bits). Just drop the translation markers for now, since the templates themselves currently do not support translations.

tests: end output lines including path with "(glob)" to pass on Windows
