Wireshark · Wireshark-dev: Re: [Wireshark-dev] Petri-Dish circumvention breaks daily-build

[Alexis La Goutte <alexis.lagoutte@xxxxxxxxx>]

Hi Roland,

Like Pascal say, we talk on last Sharkfest about Automated build/Gerrit and Infrastructure Stuff..

And it is complicated, need to make some change on actually infrastructure but missing time...

I think, we will see after Wireshark 2.0 to make some change on infrastructure.

(the idea is to have a regular build (actually trunk buildbot) before merging but can be limited the number of commit by day...

Regards,

Therefore it was decided, that no patch can be submitted without Jenkins not running at least once, but it can be overruled if necessary.

Don't worry, I did not take it personally and I can understand your frustration.
For your information making the Petri Dish step mandatory is something we discussed during last Sharkfest so it's something planned but not ready yet (I'm not in charge of the infrastructure so I'm not sure what are the missing steps; some false positives in the pre commit scripts and Petri Dish git checkout errors probably count here).

The latest being a NFS patch (#10429), where a variable is being used uninitialized. There where many patches to NFS, and the top-most one only was being sent to petri-dish, but not rebased first, which meant it was not checking the code of it's predecessors but only the one of itself.

I do not think it is fair, that non-core-developers are being sent through an extra step and core's can circumvent this step. In my opinion it should be a necessity for everyone.

Looks like I got confused at some point (I do not find Gerrit UI really intuitive for long series) as the error appeared despite my attempt and I'm sorry about that. Note that those patches were not from a non core developer, so I do not agree with your statement that this is a core vs non core extra step.
