Only do this in oss-fuzz for now.
From now on I will commit oss-fuzz work specifically to this branch. --------- Co-authored-by: Vitor Guidi <[email protected]> Co-authored-by: Ali HIJAZI <[email protected]>
Also increase the number of utasks we can get from the queue
Use randomness to "load balance" for now. --------- Co-authored-by: Vitor Guidi <[email protected]> Co-authored-by: Ali HIJAZI <[email protected]>
Scale up fuzzing on batch
1. Don't defer the tasks, they've already been deferred. 2. Improve the scheduling time by 20% by batching calls so that we only need to read YAML and query the database once, per queue read. --------- Co-authored-by: Vitor Guidi <[email protected]> Co-authored-by: Ali HIJAZI <[email protected]>
Use imap_unordered for these two improvements. 1. Async signing, we can start signing the arbitrary URLs before we are done listing and signing the existing URLs. 2. Ignoring the order means we can sign/list even faster. 3. Use of iterables means we don't need to use unnecessary memory.
We're experiencing big delays in our batch scheduling (meaning batch is an hour behind). We may have too many jobs for batch. Start trying to bunch the tasks more efficiently so we have fewer jobs.
The experiment failed because batch is throttling job creation for some reason. Lower the amount of tasks we schedule so we don't create a backlog that prevents non-fuzz tasks from being run.
It's not used anymore. Related: b/381528482

Allow utask_main scheduling
Also delete some example code.
