REVISION SUMMARY This is part of GSoC19 project `Implement abort and continue commands`. This patch is part of the continue plan. This adds the basic logic for hg continue. This command aborts an multistep operation like graft, histedit, rebase, transplant and unshelve if they are in an unfinished state. The first part of the logic is determining the unfinished operation from the state detection API under statemod. This API is extended to support hg continue by adding a method to register the abort logic as a function (here continuefunc). Once the unfinished operation is determined the registered logic is used to resume the command in case it is interrupted. The benefit of this kind of framework is that any new extension developed can support hg continue by registering the command and logic under statedetection API. hg continue currently supports --dry-run/-n flag only. It is used to dry run hg abort REPOSITORY rHG Mercurial REVISION DETAIL https://phab.mercurial-scm.org/D6645 AFFECTED FILES mercurial/commands.py mercurial/state.py CHANGE DETAILS diff --git a/mercurial/state.py b/mercurial/state.py --- a/mercurial/state.py +++ b/mercurial/state.py @@ -99,7 +99,7 @@ def __init__(self, opname, fname, clearable, allowcommit, reportonly, continueflag, stopflag, cmdmsg, cmdhint, statushint, - abortfunc): + abortfunc, continuefunc): self._opname = opname self._fname = fname self._clearable = clearable @@ -111,6 +111,7 @@ self._cmdhint = cmdhint self._statushint = statushint self.abortfunc = abortfunc + self.continuefunc = continuefunc def statusmsg(self): """returns the hint message corresponding to the command for @@ -159,7 +160,8 @@ def addunfinished(opname, fname, clearable=False, allowcommit=False, reportonly=False, continueflag=False, stopflag=False, - cmdmsg="", cmdhint="", statushint="", abortfunc=None): + cmdmsg="", cmdhint="", statushint="", abortfunc=None, + continuefunc=None): """this registers a new command or operation to unfinishedstates opname is the name the command or operation fname is the file name in which data should be stored in .hg directory. @@ -184,10 +186,12 @@ message of the format ('To continue: hg cmdname --continue' 'To abort: hg cmdname --abort') is not desired abortfunc stores the function required to abort an unfinished state. + continuefunc stores the function required to finish an interrupted + operation.
