Synchronization of Libadblockplus git repo with mercurial is broken.

[sergz]

I have committed to mercurial into master bookmark but master branch on gihub repo of libadblockplus has not been updated.
Please compare commits ​https://hg.adblockplus.org/libadblockplus/rev/master and ​https://github.com/adblockplus/libadblockplus/commits/master.

In addition

1. branch issue-3337-update-adblockplus is also not updated. I've rebased issue-3337-update-adblockplus in mercurial and used a forced push, but the branch in github has not been update to the right commit.

2. after removing of bookmark issue-3337-update-adblockplus the corresponding branch in git is not removed.

Expected behaviour

Branches in github repository should be updated when any mercurial bookmark is changed.

14:38 <sergz> matze: Hi! when could you take a look at https://issues.adblockplus.org/ticket/3886, it's quite essential, e.g. we cannot update dependencies file while git repo is not synchronized.
14:41 <matze> sergz: the issue is caused by your rebasing of that feature branch. no repository is configured to handle such cases, hence the update now rolls back the transaction when it comes to syncing that branch. i guess this just did not came to mind before. however, if my assumption is right we need to first define the expected behavior in such cases before i can tackle the ticket
14:41 <matze> fhd: ^ -- any comments?
14:42 <sergz> matze: OK, thank
14:43 <matze> sergz: in general i am not sure if the workflows fhd had in mind actually allow for forced updates at all. in the meantime you may pay me a visit and we can fix your particular sync issue manually for now

I have rebased again, here is the log of operations, could be helpful to understand.

Force-pushed to GitHub to solve this issue. Please note that we do NOT support re-basing with our synchronization mechanism yet, but need to define a strategy for such cases before we can implement that feature.

I have updated the issue, there is yet one trouble, the branch on github is not removed after removing of bookmark in mercurial.
JIC, please find the log of pushing commands

Also something not considered in the current approach, hence not supported yet.

@fhd We surely need to clarify the behavior intended, soon and in detail. The nuances start maturing from impediments to blockers..
