rebase: move storestatus onto rebaseruntime The rebaseruntime class already has the restorestatus function, so let's make it own the store status function too. This get's rid of a lot of unnecessary argument passing and will make a future patch cleaner that refactors storestatus to support transactions.

rebase: clear updatestate during rebase --abort in more cases Previously, rebase --abort would only call update if you were on a node that had already been rebased. This meant that if the rebase failed during the rebase of the first commit, the working copy would be left dirty (with a .hg/updatestate file) and rebase --abort would not have update to clean it up. The fix is to also perform an update if you're still on the target node or on the original working copy node (since the working copy may be dirty, we still need to do the update). We don't want to perform an update in all cases though because of issue4009. A subsequent patch makes this case much more common, since it causes the entire rebase transaction to rollback during unexpected exceptions. This causes the existing test-rebase-abort.t to cover this case.

repoview: convert attribute names to unicodes on Python 3 In Python 3, the attribute names must be strings i.e. unicodes.

parsers: alias long to int on Python 3

store: slice over a bytestring to get characters instead of ascii values On Python 2, >>> a = b'abc' >>> a[1] 'b' Whereas on python 3, >>> a = b'abc' >>> a[1] 98 >>> a[1:2] b'b' This does not change behaviour on python 2.

vfs: use 'vfs' module directly in 'mercurial.hg' Now that the 'vfs' classes moved in their own module, lets use the new module directly. We update code iteratively to help with possible bisect needs in the future.

vfs: extract 'vfs' class and related code to a new 'vfs' module (API) The 'scmutil' is growing large (1500+ lines) and 2/5 of it is related to vfs. We extract the 'vfs' related code in its own module get both module back to a better scale and clearer contents. We keep all the references available in 'scmutil' for now as many reference needs to be updated.

vfs: replace 'scmutil.opener' usage with 'scmutil.vfs' The 'vfs' class is the first class citizen for years. We remove all usages of the older API. This will let us remove the old API eventually.

fsmonitor: remove use of repo.opener This has been deprecated, so we need to switch to the appropriate vfs apis.

help: align description of 'base rev' with reality [issue5488] The text about revlogs seems to be wrong about -1 being used to indicate the start of a delta chain. Attempt to correct this.
