git:master:93289188: core: memset 0 the struct in first line parsing; split type and flags

by Daniel-Constantin Mierla

jsonrpc-s crash

Filtering GIT commit notifications

by Daniel-Constantin Mierla

Hello, it appears that the traffic with commits on personal branches is increasing, therefore I am trying to figure out if there is a need to filter the email notifications (being suggested to me by someone here, as well). I extended the notification script (https://github.com/miconda/gitpushub) to be able to filter on branch name and send email notifications to different addresses or skip notifying. If people think there is too much traffic with notification from personal branches, we can update to: 1) send notifications of commits to official branches (master, 4.2, 4.1, and older releases) to sr-dev 2) for the rest of commits, several options a) skip notifying them b) create another mailing list where to send all commits notifications (including for official branches) c) decide case by case - a dev can request to skip notifications to its personal branches (if she/he uses them extensevely) or the community asks to ingnore some particular branches (if it appears to be a lot of no important activity) If you think of other combinations, don't hesitate to propose here. At this moment I tend for 1, 2b). Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda
