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.
