localrepo: make journal.dirstate contain in-memory changes before transaction...
localrepo: make journal.dirstate contain in-memory changes before transaction Before this patch, in-memory dirstate changes aren't written out at opening transaction, even though 'journal.dirstate' is created directly from '.hg/dirstate'. Therefore, subsequent 'hg rollback' uses incomplete 'undo.dirstate' to restore dirstate, if dirstate is changed and isn't written out before opening transaction. In cases below, the condition "dirstate is changed and isn't written out before opening transaction" isn't satisfied and this problem doesn't appear: - "wlock scope" and "transaction scope" are almost equivalent e.g. 'commit --amend', 'import' and so on - dirstate changes are written out before opening transaction e.g. 'rebase' (via 'dirstateguard') and 'commit -A' (by separated wlock scopes) On the other hand, 'backout' may satisfy the condition above. To make 'journal.dirstate' contain in-memory changes before opening transaction, this patch explicitly invokes 'dirstate.write()' in 'localrepository.transaction()'. 'dirstate.write()' is placed before not "writing journal files out" but "invoking pretxnopen hooks" for visibility of dirstate changes to external hook processes. BTW, in the test script, 'touch -t 200001010000' and 'hg status' are invoked to make file 'c' surely clean in dirstate, because "clean but unsure" files indirectly cause 'dirstate.write()' at 'repo.status()' in 'repo.commit()' (see fe03f522dda9 for detail) and prevents from certainly reproducing the issue.
