Mercurial: Changelog

tests: slightly modify a linkrev test to prepare for expanding it The test case checks that the copy tracing code doesn't get confused by linkrevs when walking a file's ancestors. This patch chnages the test slightly so a second commit is grafted, thus producing a second "bad" linkrev. I'll use this in the next patch to demonstrate a bug.

copies: process files in deterministic order for stable tests I also fixed a typo while at it. Differential Revision: https://phab.mercurial-scm.org/D6320

narrow: send specs as bundle2 data instead of param (issue5952) (issue6019) Before this patch, when ACL is involved, narrowspecs are send as bundle2 parameter for narrow:spec bundle2 part. The limitation of bundle2 parts are they cannot send data larger than 255 bytes. Includes and excludes in narrow are not limited by size and they can grow over 255 bytes. This patch introduces a new mandatory bundle2 part and send narrowspecs as data of that. The new bundle2 part is introduced to keep things cleaner and easy to distinguish related to backward compatibility. The part is mandatory because without server's narrowspec, the local ACL narrow repo won't work. This patch makes clients compatible with servers which have older versions. However I left a comment that we should drop the other bundle2 part soon as that's broken and people should not rely on that. I named the new bundle2 part 'Narrow:responsespec' because: 1) Capital 'N' to make it mandatory 2) 'Narrow:spec' cannot be used because bundle2 enforces that there should not be two different parts which resolve to same name when lowercased. 3) reponsespec clears that they are specs which are send as reponse by the server While I was here, I renamed `narrowhgacl` section to `narrowacl` as suggested by idlsoft@ and martinvonz@.
