histedit: add verify() to histeditaction This commits splits the parsing of the histedit rule from its semantic analysis. It's necessary because sometimes we want to do first without doing the former (reading the histedit state).

histedit: add addhisteditaction decorator This decorator will is allowing us to move the registering the action in actiontable closer to the action code. Also it is storing the verb inside histedit action so the action is aware of the verb needed to trigger it.

histedit: add actions property to histedit state I want to refactor histedit to use action objects instead of (verb, rest) pairs whenever possible. At the end of this series I want the rules to be translated into action objects when reading state and translated back when writing state. All histedit internals should use action objects instead of state rules. To migrate histedti internals sequentially I'm introducing the state.actions property to translate rules on the fly so we can use both state.actions and state.rules until refactoring is done.

check-commit: remove confusion between summary line and other headers The pull url header can easily grow over 80 chars. The check-commit script was confusing this with a too long summary line. We update the regular expression to not match other header.

shelve: execute checkunfinished inside wlock scope Before this patch, "hg shelve" of shelve extension executes 'cmdutil.checkunfinished()' before acquisition of wlock. It may cause unintentional result, if another command runs parallelly (see also issue4368). To avoid this issue, this patch executes 'cmdutil.checkunfinished()' inside wlock scope of "hg shelve". This also fixes issue4957, because now 'cmdutil.checkunfinished()' isn't invoked at "hg shelve" with options below: --cleanup --delete --list --patch --stat

shelve: widen wlock scope of shelve for consistency while processing Before this patch, "hg shelve" of shelve extension executes/refers below before acquisition of wlock: - 'repo.dirstate.parents()' via 'repo[None].parents()' - 'repo._activebookmark' It may cause unintentional result, if another command runs parallelly (see also issue4368). This patch widens wlock scope of "hg shelve" of shelve extension for consistency while processing.

gpg: make sign acquire wlock before processing Before this patch, "hg sign" of gpg extension executes/evaluates below without acquisition of wlock. - repo.dirstate.parents() - '.hgsigs' not in repo.dirstate It may cause unintentional result, if another command runs parallelly (see also issue4368). To avoid this issue, this patch makes "hg sign" of gpg extension acquire wlock before processing.
