largefiles: fix profile of unused largefilesdirstate._ignore

largefiles: import whole modules instead of importing parts of them Be more friendly to demandimport.

largefiles: update should only create a .orig backup of a largefile once A .orig of a standin after the update do that a .orig of the actual largefile is created. The .orig standin was however never removed again and the largefile .orig was thus overwritten again and again. The fix: remove the standin .orig when it is used.

merge: let manifestmerge emit 'keep' actions when keeping wd version Such a 'keep' action will later be the preferred (non)action when there is multiple ancestors. It is thus very convenient to have it explicitly. The extra actions will only be emitted in the case where the local file has changed since the ancestor but the other hasn't. That is the symmetrical operation to a 'get' action. This will create more action tuples that not really serve a purpose. The number of actions will however have the number of changed files as upper bound and it should thus not increase the memory/cpu use significantly.

merge: pass merge ancestor to calculateupdates as a list The list will so far always have one element.

merge: move ancestor selection tweaking from manifestmerge to update function - passing it through calculateupdates. This will make sure manifestmerge actually use the ancestor it is given.

match: make it more clear what _roots do and that it ends up in match()._files

cat: explicitly document the supported formatter rules The previous documentation pointed to the export command, but even if the user recognized that instead of only reading the cat specific list of rules, not all of the export rules applied anyway (specifically %N, %n and %m). The new items are a copy/paste from export's list. These rules have existed since at least version 0.5. Note that %m gets substituted with 'None' because the commit message isn't passed to cmdutil.makefilename(). %R and %r are currently effectively the same, since no revwidth is passed, however they both work. There aren't any existing tests for these rules, so they are added to prevent future regression.

convert: backout 81cf597dafa9 and a3545c3104aa -closemap Closemap solves a very specific use case. It would be better to have a more generic solution than to have to maintain this forever. Closemap has not been released yet and removing it now will not break any backward compatibility contract. There is no test coverage for closemap but it seems like the same can be achieved with a simple and much more powerful custom extension: import hgext.convert.hg class source(hgext.convert.hg.mercurial_source): def getcommit(self, rev): c = super(source, self).getcommit(rev) if rev in [''' d643f67092ff123f6a192d52f12e7d123dae229f 9117c6561b0bd7792fa13b50d28239d51b78e51f f368a1c302d5b87506f7edb13769e591e063d7ea ''']: c.extra = c.extra.copy() c.extra['close'] = '1' return c hgext.convert.hg.mercurial_source = source

convert: backout b75a04502ced and 9616b03113ce - tagmap Tagmap solves a very specific use case. It would be better to have a more generic solution than to have to maintain this forever. Tagmap has not been released yet and removing it now will not break any backward compatibility contract. There is no test coverage for tagmap but it seems like the same can be achieved with a (relatively) simple and much more powerful custom extension: import hgext.convert.hg def f(tag): return tag.replace('some', 'other') class source(hgext.convert.hg.mercurial_source): def gettags(self): return dict((f(tag), node) for tag, node in in super(source, self).gettags().items()) def getfile(self, name, rev): data, flags = super(source, self).getfile(name, rev) if name == '.hgtags': data = ''.join(l[:41] + f(l[41:]) + '\n' for l in data.splitlines()) return data, flags hgext.convert.hg.mercurial_source = source

bundle2: support for push over the wire We use the new method defined in the past changeset to send a bundle2 stream and receive one in reply. The http version is missing remote output support. This will be done later using a bundle part.

httppeer: support for _calltwowaystream This new method is now supported by http too.

sshpeer: add implementation of _calltwowaystream This implements the call needed by bundle2. The error handling is a bit flaky right now, but bundle2 error handling in general is still flaky anyway. Bundle2 is still disabled by default, I do not expect this to be a problem.

wireproto: add a _calltwowaystream method on wirepeer This method will be used by bundle2 pushes. It calls a command, feeds it with a stream and receives another stream in reply. Actual implementation for ssh and http will be done in later changesets.

bundle2: return a bundle20 object from exchanges.unbundle When a bundle2 is pushed we return a bundle instead of an integer. We use to return a binary stream. We now return a `bundle20` bundler to make the life of wireprotocol implementation simpler.
