bundle2: introduce a bundleoperation object This object will hold all data and state gathered through the processing of a bundle. This will allow: - each handler to be aware of the things unbundled so far - the caller to retrieve data about the execution - bear useful object and logic (like repo, transaction) - bear possible bundle2 reply triggered by the unbundling. For now the object is very simple but it will grow at the same time as the bundle2 implementation.

bundle2: feed a unbundle20 to the `processbundle` function The unbundle can comes from multiple sources. (on disk file, peer, etc) and (ultimately) of multiple type (bundle10, bundle20). The `processbundle` is no longer in charge of creating the bundle.

bundle2: lock the repo during unbundle test We forgot the lock the repo. It's not too bad during tests, but the lock also still carry some transaction logic. (yes we need to get rid of this)

merge: keep destination filename as key in filemerge actions Gives more readable debug output and makes it possible to compare/merge actions later.

merge: keep destination filename as key in actions for merge with dir rename Avoids None: local renamed directory to b/c -> d updating:None 1/1 files (100.00%) and makes it possible to compare/merge actions later.

merge: include ancestor node in merge actions

merge with stable

repoview: use _gethiddenblockers in computehidden No functionality has changed, since we've only extracted the code into its own function. Now extensions can wrap _gethiddenblockers to provide their own blocker without polluting bookmarks or local tags.

repoview: add _gethiddenblockers method This is a standalone function that will provide the ability for extensions to wrap.

repoview: improve performance for computehidden (issue4206) For repos with a large number of heads (including hidden heads), a stale tag cache would cause computehidden to be drastically slower because of a the call to repo.tags() (which would build the tag cache). We actually don't need the tag cache for computehidden because we filter out global tags. This patch replaces the call to repo.tags with readlocaltags so as to avoid the tag cache.

tests: remove unused variables from test-pathencode.py caught by pyflakes

shelve: remove unused variable caught by pyflakes

changegroup: remove unused variable caught by pyflakes

hgk: use hg export to write commits Instead of calling internal command, use hg export to produce changeset diffs compatible with hg import directly.

hgk: add .diff extension when exporting commits Append the .diff extension automatically.

localrepo: move the addchangegroup method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had few callers, not enough to be kept in local repo.

localrepo: move the addchangegroupfiles method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had a single caller, far too few for being kept in local repo.

localrepo: move the changegroup method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had few callers, not enough to be kept in local repo. The peer API stay unchanged.

localrepo: move the getbundle method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had few callers, not enough to be kept in local repo. The peer API remains unchanged.

store: drop unused existing list

localrepo: move the getlocalbundle method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had 3 callers total, far too few for being kept in local repo.

localrepo: move the changegroupsubset method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had few callers, not enough to be kept in local repo. The peer API remains unchanged.

localrepo: move the changegroupinfo method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had a single caller... already in this changegroup module.

localrepo: move the _changegroupsubset method in changegroup module This is a gratuitous code move aimed at reducing the localrepo bloatness. The method had 3 callers total, far too few for being kept in local repo.

push: pass a `pushoperation` object to localrepo.checkpush The `pushoperation` object contains strictly more data the arguments currently passed to `localrepo.checkpush` we pass the new object instead. This function is used by MQ to abort push that includes MQ changesets. Note: extension that may use this function will have to align.
