how create github mirror external git repository, such appears "real mirror", e.g., in https://github.com/mirrors ? so far, set mirror using: cd /path/to/bare/repository git remote add --mirror github git@github.com:user/repo.git and configure post receive hook git push --quiet github . way, however, github not recognize mirror. any ideas how github way, such "mirrorred from" appears underneath repostiory name? based on communicating github's support team, found github offers no direct mechanism user mirror repositories in fashion. however, 1 can ask github install service repositories part of organization. github configures existing repository such mirror , pulls in interval function of number of overall mirrors have. edit : stuart points out, github no longer accepts requests mirroring arbitrary repositories. remaining option solution posted in question, i.e., creating post-receive hook automatically push github repository.

from client application sending request/transaction (containing operation perform (and parameters) + transactionid) remote queue. remote server dequeue request @ point , takes time process it. once done processing it, sends reponse on client queue (containing applicative response + transactionid) ... totally "disconnected" communication mode, way client can map response request via transactionid. message response dequeued on client side, , matched original request (based on transactionid). what doing right when client post request server queue, adds callback dictionnary keeping transactionid , callback (delegate). dictionary<int, object> mapping transactionid callback call result of operation. the callbacks/delegates stored object due fact depending of request, callback delegate signature different (for example response may return list<string> whereas response may return int ). when client queue dequeues response, knows type of response (and therefore corr...

dr macro says : in practice rare namespace prefixes clash because namespaces known , defined conventional prefix unique among set of namespaces combined (again, more general case of willy-nilly combination of unexpected stuff doesn't happen). nevertheless, i'd pick namespace prefix isn't in common use. guess google intended prefix(es), know of list of conventional prefixes, ideally measure of how common/obscure are? the important thing namespaces prefix arbitrary , can changed. isn't prefix standardized, namespace url, , won't conflict because use domain registration system prevent conflicts.

i've coded myself corner sort of data abstraction scheme , it's resulted in needing editoropened(qmodelindex) , editorclosed(qmodelindex) signals in views (qtableview exclusively). the reason being data classes have automatic behavior needs block/disabled during editing, re-enabled afterwards. at first thought try custom delegates ran problems couple reasons: 1 being seems bit excessive use custom delegate providing same behavior every single item, in other words seems ought done items view itself. second problem being delegates seem const prevents me setting internal handle data object within delegate. looking @ view methods, found qabstractitemview::edit , qabstractitemview::closeeditor perfect candidates re-implementing opened() , closed() signals, need index/handle specific item being edited, don't think can obtain within methods... at point have no idea else do. i'd appreciate tips or pointers in right direction! reading i solved on own... i found qabstr...
