mq: check subrepo synchronizations against parent of workdir or other appropriate context Before this patch, MQ checks each subrepo synchronizations against the working directory context, so ".hgsubstate" updating is not imported into MQ revision correctly in cases below: - qrefresh when current ".hgsubstate" is already synchronized with each subrepos: you can reproduce this easily by just twice or more qrefresh invocations - qnew just after rollback of commit which updates ".hgsubstate" This patch resolves this by checking subrepo states against: - the parent of "qtop" for qrefresh, or - the parent of working context otherwise

mq: create patch file after commit to import diff of ".hgsubstate" at qrefresh Even though the committed revision contains diff of ".hgsubstate", the patch file created by qrefresh doesn't contain it, because: - ".hgsubstate" is not listed up as one of target files of the patch for reasons below, so diff of ".hgsubstate" is not imported into patch file - status of ".hgsubstate" in working directory is usually "clean" - ".hgsubstate" is not specified explicitly by users - the patch file is created before commit processing which updates or creates ".hgsubstate" automatically, so there is no diff for it at that time This patch resolves this problem by: - putting ".hgsubstate" into target list of the patch, if needed: this allows "patch.diff()" to import diff of ".hgsubstate" into patch file. - creating the patch file after commit processing: this updates ".hgsubstate" before "patch.diff()" invocation. For the former fixing, this patch introduces "putsubstate2changes()" to share same implementation with qnew. This is invoked only once per qnew/qrefresh at most, so there is less performance impact. This patch also omits "match" argument for "patch.diff()" invocation, because "patch.diff()" ignores "match" if "changes" is specified.
