From: "Eyal Edri" <eedri(a)redhat.com&gt; To: "engine-devel" <engine-devel(a)ovirt.org&gt; Cc: "infra" <infra(a)ovirt.org&gt; Sent: Tuesday, July 9, 2013 11:38:51 AM Subject: [Engine-devel] Proposal for new commit msg design for engine commits Hi, You all probably know and familiar with 'ovirt-engine' git hook for commit msg template [1]. this helps understand the general area of the patch in the project but it lacks additional info that might be valuable for scaling automatic tests in Jenkins CI. Let me explain: Infra team is working hard on expanding oVirt CI infrastructure and adding more tests in jenkins (per commit/patch). Adding important meta-data per patch can significatly improve the ability to run specific tests for each patch/commit, and not waste valuable resources on Jenkins jobs that are not relevant to the code in the patch. So the idea is to add/expand current metadata per patch, in the form of: (either) 1. expanding current header template to include more data like 'network' , 'setup', 'tools', 'virt' 2. adding a new label with relevant tags for the patch, called e.g 'METADATA: network, rest, virt' Jenkins jobs will then be able to parse that data and trigger only relevant jobs for it. this can also allow us to add more jobs per patch, an option that is very problematic today considering the amount of patches coming in to engine. Once agreed on a format, we'll be able to add a git hook to verify the validity of the commit msg. (similar to bug-url). if we're not 100% sure that the tags will cover all corner cases and we feel like we need to run the code on all jobs, we can a nightly job to run all the remaining jobs (but at least it won't run on every patch/commit).

I like the idea of having a label in the bottom part of the commit that is: METADATA: network

which would be your second proposal. ----- Original Message ----- > From: "Eyal Edri" <eedri(a)redhat.com&gt; > To: "engine-devel" <engine-devel(a)ovirt.org&gt; > Cc: "infra" <infra(a)ovirt.org&gt; > Sent: Tuesday, July 9, 2013 11:38:51 AM > Subject: [Engine-devel] Proposal for new commit msg design for engine commits > > Hi, > > You all probably know and familiar with 'ovirt-engine' git hook for commit > msg template [1]. > this helps understand the general area of the patch in the project but it > lacks additional info that might > be valuable for scaling automatic tests in Jenkins CI. > > Let me explain: > > Infra team is working hard on expanding oVirt CI infrastructure and adding > more tests in jenkins (per commit/patch). > Adding important meta-data per patch can significatly improve the ability to > run specific tests for each patch/commit, > and not waste valuable resources on Jenkins jobs that are not relevant to the > code in the patch. > > So the idea is to add/expand current metadata per patch, in the form of: > (either) > 1. expanding current header template to include more data like 'network' , > 'setup', 'tools', 'virt' > 2. adding a new label with relevant tags for the patch, called e.g > 'METADATA: network, rest, virt' > > Jenkins jobs will then be able to parse that data and trigger only relevant > jobs for it. > this can also allow us to add more jobs per patch, an option that is very > problematic today considering the amount of > patches coming in to engine. > > Once agreed on a format, we'll be able to add a git hook to verify the > validity of the commit msg.

I agree with Alon here that the Ci informations don't belong in the commit msg. My opinion is that a testcase should know what it covers. This information from the testcase can then be used by any party to determin if the testcase should be run on a specific commit (which yields informations about the changed paths, files, owner, author, etc ... which might be valuable).

This > information from the testcase can then be used by any party to determin > if the testcase should be run on a specific commit (which yields > informations about the changed paths, files, owner, author, etc ... > which might be valuable). i think you're missing the point here. can you explain how do you propose a test case will know "what it covers"? let's take an example: let's say a new commit comes from ovirt-engine: http://gerrit.ovirt.org/#/c/16668/ commit msg: "core: Use images instead of volumes at CDA message". now you have 1000 test cases (could be system or functional test). (let's assume that your infra can't support running 1000 tests per patch/commit). Some of these test suits checks network flow, some virt (migration/template for e.g), some host install, others storage flows and so on... ). you have one repo to clone (ovirt-engine, let's keep vdsm a side for a min), and to compile the project from for the tests. now given this scenario, please explain how will you know which test from the 1000 you have you'll run on it. do you believe that according to the author/path/filename you'll know if that patch involves storage or virt scenario? i don't think there's an alternative to a metadata to assist mapping the patch to a relevant "topic" in the code. whether it exists as a git note or a label in the commit, that's another matter and probably less important.

I don't think it should be by patch bases, but common logic based of metadata, if we do this within source tree maintainer can choose which tests he wish to have by simply commit metadata into the source tree. Asking for a special test can always be done in jenkins post commit, or by some generic field in gerrit. However, the standard test suites is something that should be applied via policy of the component in question using approved metadata.

Hey Eyal, Yes - I would at least give it a try to decide automagically what tests to run by looking at the change. The main motivation for this is to not add another things which the committer needs to take care of and IMO we humans tend to fail (at some point) on those boring tasks like adding correct metadata (let it be a typo or just not adding the correct testsuites/topis to be run).

But let's get back to your example. Basically we can use the path and filename to determin what testsuite to run. Testsuites could be bound to paths and/or filenames and/or regexes being matched against the full filename. Another approach would be to use a java package dependency tree to determine which classes are directly and indirectly affected by a change. This information can then be used to also build a set of testsuites to be run. For example: World uses Ocean uses Wale uses Cell - if Wale changes, we'll surely want to run the testsuites assigned to the classes higher up in the dependency chain (World and Ocean). For the concrete example above: Maybe there is a spell checker testcase which could be bound to the filename glob pattern *.properties. > i don't think there's an alternative to a metadata to assist mapping the > patch to a relevant "topic" in the code. > whether it exists as a git note or a label in the commit, that's another > matter and probably less important. The idea is to use the path/filename and dependency tree information to model these topics. Example: WaterTestsuite(Topic): regex_in_change: .*\.fish glob_in_change: src/classes/ocean/*.java path_in_change: src/classes/water.java change_affects_depency_of: WaterClass

But surely labels or meta-data in the commit msg are quicker to implement. - fabian > eyal. > > > > > - fabian > > > > _______________________________________________ > > Engine-devel mailing list > > Engine-devel(a)ovirt.org > > http://lists.ovirt.org/mailman/listinfo/engine-devel > >

Nevertheless, i have no problems with your suggestions for metadata per directory to map all ovirt code. any suggestion how to push it forward?

The developer, the qe, the ci and the infra people. This mechanism is to avoid running all the tests all the time. Of course there are some times when all the tests should be run to make sure nothing else changed, but most times you just need to run part of them to make sure you did not break something obvious. > > And maybe there are 50 tests of network, and you need only 5 of them for > the specific change, how do you mark it, so now a developer need to know > any test? what if you add one tomorrow which is relevant to a similar > change? how do you inform the developer that now he needs 6? As I said before, what the developer specifies is not a list of tests, but a list of components, that qe has to map to different sets of tests that can change with time. So specifying webadmin will run all the tests in that group, that might be only one, or 100, and might be increasing/decreasing with time transparently for the developer. Adding a new component is not common and there's no need to do it so frequently. > > Why should it be the developer responsibility and not the quality ensuring > engineer responsibility to determine which tests should run and when? Of course it's the responsibility of the qe engineer to determine when and which tests should be run. But this is meant to be a new tool for the developer not a substitute for the full qe tests, so the developer can easily make sure that he's changes do not break anything obvious before starting the real tests (that will take more time and resources). The developer just adds some metadata so the qe engineer can decide which tests to run per patch, so it's on qe's hand in the end to decide if ignore or not the metadata and which tests to run. > > As far as this template was not actually used for anything but humans, it > was not that important, but once you formalize it as an interface, I step > forward and state that the subject line is not the right tool for the task > at hand (or any for this matter).

That's just not true. The sources are complicated enough to make two changes in the same file to affect different components. Any reused code is prone to affect multiple components, making it really hard to determine by which changed files which tests to run. And if you go down to the function/class level it's even harder to decide and to maintain. And of course it's not human error free, as the metadata in the files/directories is defined and maintained by a human. And in my opinion is a lot harder to implement and maintain, and a lot less agile, and does not get rid of the human factor.

That's true, but I think that maybe putting metadata in each file is overkilling. One file in the root of the repo with a few lines should be enough for that afaik.

Or until we have tags in the messages, for the same reasons. Don't forget that metadata within source is also a 'manual workaround or solution', as someone has to maintain all the metadata in all the files/directories (maybe for that purpose will be better to have just one file with all that metadata, depending on which level of granularity we need to map all the files).

I think that having to maintain metadata in all the files is way more annoying, but yes, as you say adding metadata to each file gives a lot more information, but only if it's up to date.

That will make labels fit our purpose, and avoid having to add tags, metadata and all that, but it's not done yet. I'll gladly add that feature, but I'm not familiar with java or gerrit code, so I might not be the best person to do it, I'm sure that it will take a lot more time for me than the other options (Eyal, any comment?). If you are fluent with java and you want to help you are very welcome :)
