context: avoid writing outdated dirstate out (issue5584) Before this patch, workingctx.status() may cause writing outdated dirstate out, if: - .hg/dirstate is changed simultaneously after last loading it, - there is any file, which should be dirstate.normal()-ed Typical issue case is: - the working directory is updated by "hg update" - .hg/dirstate is updated in background (e.g. fsmonitor) This patch compares identities of dirstate before and after acquisition of wlock, and avoids writing outdated dirstate out, if change of .hg/dirstate is detected.

If you just want a checklist to follow, you can go straight to

https://www.mercurial-scm.org/wiki/ContributingChanges#Submission_checklist

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
