contrib: add debugshell extension

log: document the different phases in walkchangerevs

log: slowpath: only walk specified revision range during preparation Even with --removed, it does not make sense to examine changesets outside of the revision range that was specified by the user: the last phase only yields a subset of (revs), preparation phase hence only has to examine (revs) to fill correctly fncache.

revert: rename original to .orig instead of copying (issue2282) By renaming before reverting the content of the file we ensure that we handle and break hardlinks properly. Handling of other hardlinks to .orig is somebody elses problem.

inotify: make inotifydirstate.status() returns a tuple of lists. This makes it consistent with dirstate.status(), which is important if there are other extensions messing with the output of status(). Those extensions can safely assume that dirstate.status() returns a tuple of lists, because its docstring says it does. But inotifystatus.dirstate() returns a list of lists, which can break those other extensions.

protocol: move the streamclone implementation into wireproto

protocol: use generators instead of req.write() for hgweb stream responses

protocol: wrap non-string protocol responses in classes

protocol: convert StreamException to generated error code This makes it much easier to handle these errors at the transport level.

protocol: extract compression from streaming mechanics

protocol: rename send methods to get grouping by prefix

protocol: shuffle server methods to group send methods

protocol: do not translate error messages on the remote side

protocol: use return shortcut instead of respond function

protocol: command must be checked before passing in

tests: rename some tests to help grouping

keyword: add extra datefilters in a single update call

cmdutil: fix accidental name clash with revrange function The revrange function was used further up, and when a local variable is defined with the same name, the earlier call to revrange becomes a 'local variable used before assignment' error. The clash was introduced in 890ad9d6a169.

commands: fix update's help to be more accurate Branches can have multiple heads, so it doesn't make sense to speak of "the head of the current branch". What update really does is try to update to the *tip* of the current branch.

i18n: use encoding.colwidth() for correct column width Some encoding and language combinations (e.g.: UTF-8 and Japanese) cause encoding characters into sequence of bytes more than column width of them. So, encoding.colwidth() should be applied instread of len() on i18n strings. In addition to it, formatting by '%*s'/'%-*s' also uses "number of bytes" to calculate space padding size, and should be fixed, too.

log: slowpath: do not read the full changelog When in the slowpath, we are examining _all_ changesets in revs. We need to order reads so they happen increasingly for I/O performance. Increasing windows were used to read changelog backwards in a windowed manner, reading the changelog forward inside each window. But since no revision range was specified, it was equivalent to reading the full changelog, even if a single revision was passed to the commandline. When --removed is used, we _need_ to scan all changesets, but if we're only looking for file patterns, this is not necessary and we can stick to the revspec that was given to us.

log: remove increasing windows usage in fastpath The purpose of increasing windows is to allow backwards iteration on the filelog at a reasonable cost. But is it needed? - if follow is False, we have no reason to iterate backwards. We basically just want to walk the complete filelog and yield all revisions within the revision range. We can do this forward or backwards, as it only reads the index. - when follow is True, we need to examine the contents of the filelog, and to do this efficiently we need to read the filelog forward. And on the other hand, to track ancestors and copies, we need to process revisions backwards. But is it necessary to use increasing windows for this? We can iterate over the complete filelog forward, stack the revisions, and read the reversed(pile), it does the same thing with a more readable code.
