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().

manifestdict: inline _intersectfiles() The _intersectfiles() method is only called from one place, it's pretty short, and its caller has to be aware when it's appropriate to call it (when the number of files in the matcher is not too large), so let's inline it.

manifestdict._intersectfiles: avoid one level of property indirection We have already bothered to extract "lm = self._lm", so let's use "lm" where possible.

manifestdict.matches: avoid name 'lm' for a not-lazymanifest

commands: add ui.statuscopies config knob statuscopies enables viewing of copies and moves in 'hg status' by default.

changelog: inline revlog.__contains__ in case it is used in hot loop Currently __contains__ is called only by "rev()" revset, but "x in cl" is a function that is likely to be used in hot loop. revlog.__contains__ is simple enough to duplicate to changelog, so just inline it.

bookmarks: show detailed status about outgoing bookmarks Before this patch, "hg outgoing -B" shows only difference of bookmarks between two repositories, and it isn't user friendly. This patch shows detailed status about outgoing bookmarks at "hg outgoing -B". To avoid breaking backward compatibility with other tool chains, this patch shows status, only if --verbose is specified,

bookmarks: show detailed status about incoming bookmarks Before this patch, "hg incoming -B" shows only difference of bookmarks between two repositories, and it isn't user friendly. This patch shows detailed status about incoming bookmarks at "hg incoming -B". To avoid breaking backward compatibility with other tool chains, this patch shows status, only if --verbose is specified,

bookmarks: enhance test of showing detail about incoming/outgoing bookmarks

bookmarks: show outgoing bookmarks more exactly Before this patch, "hg outgoing -B" shows only bookmarks added locally. Then, users can't know about bookmarks below before "hg push" execution. - deleted locally (even though it may be added remotely from "hg pull" view) - advanced locally - diverged - changed (= remote revision is unknown for local) This patch shows such bookmarks, too.
