Description

« Hide

We noticed an issue while checking out a repository with shelve support.
It looks like all agents checking out the repository all do a p4 print of the files for diffing in the UI.
Shouldn't the master or the server be in charge of that ? and not every agents ?
I've not been able to confirm if they all do different files, or if each agent can reprint a file already printed by another agent.

Are you checking out same copy of the repository on multiple build agents in a single build?

Yes, what we usually do is :
Have a parallel step, then a composite for separate agents.
And in each of this composite step, check out of the repository.
Should we do something different ?

That is a reasonable use case. Right now QB records contents of unshelved files upon checkout, and we should find a way to avoid doing this multiple times when multiple checkouts are ongoing.

That would be great, with +5K files shelved we see a drastic performance impact
