templatekw: have {manifest} use ctx.manifestnode() for consistency changeset_printer was updated at f57640bf10d4 to not access changeset by index.

subrepo: use vfs.reljoin instead of os.path.join

subrepo: inline reporelpath into abstractsubrepo._relpath to centralize logic "reporelpath()" is referred only from "abstractsubrepo._relpath()".

subrepo: add _relpath field to centralize subrelpath logic This patch adds propertycache-ed "_relpath" field to "abstractsubrepo", to centralize "subrelpath" logic into it. Now, "subrelpath()" can always return "_relpath" field of the specified subrepo object, because it is ensured that subrepo object has it. To reduce changes in this patch, "subrelpath()" itself is still kept, even though it seems to be redundant. This is also a part of eliminating "os.path.*" API invocations for "Windows UTF-8 Plan".

subrepo: add wvfs field to access the working directory via vfs This patch doesn't create vfs object in "abstractsubrepo.__init__()" but adds propertycache-ed "wvfs" field, because the latter can: - delay vfs instantiation until it is actually needed - allow to use "hgsubrepo._repo.wvfs" as "wvfs" "hgsubrepo._repo" is initialized after "abstractsubrepo.__init__()" invocation, and passing "hgsubrepo._repo.wvfs" to "abstractsubrepo.__init__()" is difficult.

subrepo: change arguments of abstractsubrepo.__init__ (API) This patch passes "ctx" and "path" instead of "ui" to "abstractsubrepo.__init__()" and stores them as "_ctx" and "_path" to use them in subsequent patches. This also removes redundant field initializations in the constructor of classes derived from "abstractsubrepo".

treemanifest: optimize treemanifest._walk() to skip directories This makes treemanifest.walk() not visit submanifests that are known not to have any matching files. It does this by calling match.visitdir() on submanifests as it walks. This change also updates largefiles to be able to work with this new behavior in treemanifests. It overrides match.visitdir(), the function that dictates how walk() and matches() skip over directories. The greatest speed improvements are seen with narrower scopes. For example, this commit speeds up the following command on the Mozilla repo from 1.14s to 1.02s: hg files -r . dom/apps/ Whereas with a wider scope, dom/, the speed only improves from 1.21s to 1.13s. As with similar a similar optimization to treemanifest.matches(), this change will bring out even bigger performance improvements once treemanifests are loaded lazily. Once that happens, we won't just skip over looking at submanifests, but we'll skip even loading them.

import-checker: force 'fcntl', 'grp', 'pwd', and 'termios' to stdlib modules These are Unix only, and caused these additional warnings on Windows if they aren't hardcoded as stdlib: mercurial/posix.py mixed imports stdlib: errno, getpass, os, socket, stat, sys, tempfile relative: grp, pwd, unicodedata mercurial/posix.py mixed imports stdlib: re relative: fcntl mercurial/posix.py mixed imports stdlib: array relative: termios Additionally, this was missing on Windows: mercurial/crecord.py mixed imports stdlib: fcntl, termios relative: curses https://docs.python.org/2/library/fcntl.html https://docs.python.org/2/library/grp.html https://docs.python.org/2/library/pwd.html https://docs.python.org/2/library/termios.html

import-checker: allow *.pyd based stdlib modules These are Windows dlls, and eliminate the following import check diffs that are not on Unix: mercurial/changegroup.py mixed imports stdlib: os, struct, tempfile, zlib relative: bz2 mercurial/encoding.py mixed imports stdlib: locale, os relative: unicodedata

manifest.walk: join nested if-conditions This makes it more closely match the similar condition in manifestdict.matches().
