topicmap: add compatibility for branchcache that now uses self._entries

evolve: fix over-idented block

tests: create "private" repository in already-updated state I'm going to add more copies of the repo and it's easier to work with the repo if it's already been updated.

branching: merge with stable

touch: use action "touch", not "<function touch at ...>", in precheck I just got this message: abort: cannot <function touch at 0x7fde174b69b0> public changesets: f177c51ae98f It has been this way since 1b7b9acda2a9 (touch: use precheck to validate revision, 2017-07-23).

prune: use action "prune", not "touch", in precheck We have been using "touch" since 06ee4ec88190 (prune: use precheck to validate revision, 2017-07-23). That commit modified the tests, so it kind seemed intentional, but I suspect it was still just an oversight.

evolve: test a common case of public divergence evolve: in pubdiv, handle the case when public branch is behind the mutable In public divergence, when public branch is behind the mutable one the behaviour that this patch added is that we relocate the draft one to public side. This should be fine in most case, but might be an issue in some other (eg, when the draft side of the divergence is rebase away from ancestors it relies on.) Test written by Pierre-Yves David <pierre-yves.david@octobus.net>

evolve: add condition in case of pubdiv to not swap the two div csets In public divergence, we have pinned the public cset to the local side when merge is performed. And in divergence resolution implementation divergent cset is the one who is kept at the local side, so to say this in one line: we have pinned public cset to the divergent side. However, in some cases we need to swap the "divergent" and "other" but we can't swap them in case of public divergence as thought would cause an error because of not being able to relocate public cset.

evolve: add logic to handle a particular case in divergence resolution Case is: In content divergence, to check if the two csets are on different parent or same parent what we do is find gca of the two csets and then compare it with the singlesuccessors of two csets's parents. Now, if gca is same as singlesuccessors of both the csets then we conclude that both are on the same parent which is not totally correct as it is possible that both the parents of two csets are obsolete with a single successor. This patch adds the logic to cover the above metioned case correctly, deciding the part when we need to relocate a cset to other side while resolving the stack of divergent csets. Changes in test file demonstrate that before this patch we were not doing it right because it should have relocated every node to other side instead of just relocating the first one from the stack.

evolve: add a test reflecting wrong behaviour of content-div resolution This patch shows that currently the case when stack of divergent csets have different parents is not handled correctly. For a stack of csets which has different parent, right behaviour is to relocate every node before performing merge but present implementation only relocate first cset in the stack and skip relocation for the rest of csets, this is not what we expect it to do. Next patch will be about fixing this issue.

compat: add support for new arg name in memfilectx.__init__ This makes us compatible with 550a172a603b (memctx: rename constructor argument "copied" to "copysource" (API), 2019-03-19).

evolve: preserve compatibility for hg < 4.8 versions This patch make sure evolve don't break if user using a version of hg before this 7694b685bb10 patch on hg-committed.
