check-code: grep's context flags don't need an extra space before number A bit of useless trivia found while researching this: OpenBSD's grep's -C has a default value (of 2) and disallows space before the argument (while -A and -B allow).

dirstate: make map implementation overridable Other implementations of dirstate will want to replace the class used for the dirstate map. Allow this to happen by making the class an attribute of the dirstate. Differential Revision: https://phab.mercurial-scm.org/D1347

fsmonitor: only access inner dirstate map if it is available As part of the dirstate refactor, fsmonitor was updated to directly access the inner map of the dirstatemap object. Dirstatemap reimplementations may not use a map like this, so only access it if it is there. Differential Revision: https://phab.mercurial-scm.org/D1346

dirstate: add explicit methods for querying directories (API) The set-like object returned by dirstate.dirs may be difficult for other implementations of the dirstate to provide, and is unnecessary as it is only ever used for __contains__. Instead, provide an explicit method for testing for a directory. .. api:: dirstate no longer provides a `dirs()` method. To test for the existence of a directory in the dirstate, use `dirstate.hasdir(dirname)`. Differential Revision: https://phab.mercurial-scm.org/D1345

dirstate: remove _droppath method This method now doesn't do very much interesting and can be removed. The updated files set can be updated where _droppath was originally called. Differential Revision: https://phab.mercurial-scm.org/D1344

dirstate: move dropping of folded filenames into the dirstate map When dropping files from the dirstate, the corresponding entry in the filefoldmap is also dropped. Move this into the dirstate map object. A future implementation of the dirstate will maintain the filefoldmap differently. Differential Revision: https://phab.mercurial-scm.org/D1343

dirstate: move management of the dirstate dirs into the dirstatemap The dirstate dirs object is owned by the map, so move management of that object there. A future implementation of the dirstate will manage the dirs object differently. Differential Revision: https://phab.mercurial-scm.org/D1342

dirstate: move management of nonnormal sets into dirstate map The dirstate map owns the nonnormal sets, and so should be the class to update them. A future implementation of the dirstate will manage these maps differently. The action of clearing ambiguous times is now entirely controlled by the dirstate map, so it moves there too. Differential Revision: https://phab.mercurial-scm.org/D1341

dirstate: add explicit methods for modifying dirstate Instead of assigning dirstatetuple objects to entries in the dirstate, move responsibility for creating tuples into the dirstatemap. Differential Revision: https://phab.mercurial-scm.org/D1340

dirstate: document dirstatemap interface Differential Revision: https://phab.mercurial-scm.org/D1380

bundlerepo: rename "bundlefilespos" variable and attribute Strictly speaking, this variable tracks offsets within the changegroup, not the bundle. While we're here, mark a class attribute as private because it is. .. api:: Rename bundlerepo.bundlerepository.bundlefilespos to _cgfilespos. Differential Revision: https://phab.mercurial-scm.org/D1384

bundlerepo: rename "bundle" arguments to "cgunpacker" "bundle" was appropriate for the bundle1 days where a bundle was a changegroup. In a bundle2 world, changegroup readers are referred to as "changegroup unpackers." Differential Revision: https://phab.mercurial-scm.org/D1383

bundlerepo: use early return I like avoiding patterns that lead to the pyramid of doom. Differential Revision: https://phab.mercurial-scm.org/D1382

test-pattern: actually update tests using the patterns We mass update the tests now. This will help the next soul touching the http protocol.

test-pattern: substitute the HTTP log timestamp too We add a pattern matching the infamous timestamp in http log. Now, we should be able to have change appears in https log without having to re-glob the whole thing over and over.

test-pattern: register the current the bundle2 capabilities string The bundle capabilites are sent with every getbundle ssh connection. Every time the protocol is updated, that string is altered. We get the part about bundle2 string replaced by $USUAL_BUNDLE2_CAPS$ so that we only have to change the substitution whenever this happens.
