That reminds me that I should check in on the current status of recheck support at Loongson lab. There was some further development on this feature last year, with the options available to users on the DPDK mailing list explained here: https://core.dpdk.org/testing/#requesting-a-patch-retest So, the default behavior is rechecking patches "as is" given the commit they were originally applied on, and there is also support for re-applying to current HEAD of a branch, and specifying a particular branch to apply the series on before retesting. This is accomplished with a "rebase" argument as you can see in the link above. I'm guessing that you don't currently have support for this rebase argument, since we haven't synced on it. Can you describe what recheck functionality is currently available for Loongson? We also need to update the dpdk.org testing page I linked in order to indicate that recheck support extends beyond UNH and the github robot. By the way, we haven't heard from you in a CI meeting in a while. Not a big deal, I know the timezone aspect between Asia, North America, and Europe is challenging. However, we are going to look at rescheduling the CI meetings in order to see whether we can find a timeslot which works better for all the lab maintainers. You'll get a survey to that end in your mailbox shortly. Thanks!

Hi Patrick,

I'm sorry for this serious delay.

I do believe that retesting is meaningful and Loongson lab should support it. Meanwhile, the email based retest framework is wonderful and it is not too hard to integrate the retest function into the existed dpdk-ci framework. Although I am responsible for the Loongson lab, I'm not full-time on it. So, I need some time to support the email based retest function in Loongson lab. It may take a few weeks.


Perfect! And take the time you need, thanks.
Thanks. I will make it a priority.

Thanks for pointing it out. This script is very useful and it can help us more easily support the retest function.

But, I got an empty output when I tried to get the retest requests since 2023-08-01 as following:

# python3 tools/get_reruns.py -ts 2023-08-01 --contexts "iol-compile-amd64-testing,iol-broadcom-Performance,iol-unit-arm64-tes= ting,github-robot"

=C2=A0=C2=A0=C2=A0 "last_comment_timestamp": "2024-02-28T02:27:49.500680"
}
Or am I using this script wrong?


Yes one correction, you should do a space delimited list of patchwork test contexts, not a comma delimited list. No quotation marks needed.

=C2=A0# python3 tools/get_reruns.py -ts 2023-08-01 --context= s iol-compile-amd64-testing iol-broadcom-Performance iol-unit-arm64-testing github-robot
Thanks. I got the expected results.

Hi=C2=A0Zhoumin,

I wanted to reach out to you about the possibility of adding the Loongson lab to the group of labs supporting the email based retest framework. Currently, the UNH Community Lab and also the GitHub Robot are supporting patch retest requests from emails, and we would like to extend that to all the publicly=C2=A0reporting C= I labs, if possible.=C2=A0


Aaron announcing support for the github robot:=C2=A0https://inbox.dpdk.org/ci/f7te= dfooq6k.fsf@redhat.com/

And the retest framework definition on the dpdk.org testing page:=C2=A0https://core.dpdk.or= g/testing/#requesting-a-patch-retest

So a format like:

Recheck-request: iol-compile-amd64-testing, iol-broadcom-Performance, iol-unit-arm64-testing, github-robot

Is current accepted, and it would=C2=A0be great = if we could add Loongson support to the list too. What we are supporting right=C2=A0now is doing retesting on the original DPDK artifact created for a patch when that patch was submitted. But we are also thinking of adding in rebasing off of tip of branch as a v2 feature.=C2=A0

I think the stateless retesting is more easily to implement the retest function.

I wrote a script to report the CI failures from Loongson lab three times a day by fetching the test results from patches.dpdk.org. This script can help me find the CI failures in time. So, sometimes I manually triggered the DPDK CI test in Loongson lab as a retest for some patches or series when I found there is a test failure caused by Loongson lab self. In this case, the retest follows the routines of normal test. So, it will always do rebasing before applying the patches or series when do this kind of retest.

I think it is simpler for Loongson lab to implement the retest function. I think it is also feasible to do the retesting on the original DPDK artifact created for a patch when that patch was submitted. But, I need some times to reconstruct the existed routines.


Thanks. I figured retest off of=C2=A0latest commit/tip of branch might be easier. Going from the original DPDK artifact is easy for UNH since we hold onto the original DPDK artifacts for a long time, but I realize other labs may not do this. So, if you can only support retest off of tip of branch right now, that is okay, we just need to ensure we are only triggering that retest when users actually request that. I.e. right now if someone submits a recheck request according to the format above, the expectation is that that retest is from the patch applied onto the branch commit which existed at the time when that patch was submitted, not latest. So, Loongson should not do anything in that case if the lab cannot support it. On the other hand, as you can see in the conversation linked below, we are looking to add support for retests off of tip of branch (when users request it), and it sounds like you can support that. So maybe we can do that support first for Loongson. I just want to verify that when a user requests a retest with some args included, we are definitely retesting according to those args in their retest request.=C2=A0

The Loongson lab doesn't hold onto the original DPDK artifacts. But, we can store the latest commit ID of the guessed branch into file when CI system firstly tests the submitted patch or series and then generate the DPDK artifact based on that commit ID if we need retest the patch or series from the time when that patch was submitted. So, I estimate that Loongson lab can support this kind of retest. I figured that requesting a retest with some args can also be supported if we can parse these args correctly in get_reruns.py.


If you can comment on this thread about whether it makes sense for the Loongson lab, that helps us make sure we're not going in a direction which will cause problems for other labs. Thanks!

Sure, my pleasure.


How do you think of it?

Best Regards,

Min Zhou

Does this sound possible for the Loonson lab? I know you are leveraging the dpdk-ci repo for standing up your CI testing, but I don't know specifically whether that lends itself well towards doing retests later, or if that would be a big technical challenge. Let me know!=C2=A0

If it is possible for the=C2=A0Loongson lab, may= be we can discuss in the March 7 CI Testing meeting?
