use of repo_poller in builders.pyl

[Mike Frysinger]

i'm a bit puzzled by how repo_poller works.  the brillo builders.pyl has this:

  "schedulers": {

    "brillo_aosp_master_poller": {

      "type": "repo_poller",

      "branch": "master",

      "repo_url": "https://android.googlesource.com/brillo",

    },

  },

but https://android.googlesource.com/brillo isn't a git repo itself ... the manifest repo is here:

  https://android.googlesource.com/brillo/manifest

how does this work ?  the bot is running when there are changes ...

i ask because the weave builders.pyl has:

  "schedulers": {

    "weave_aosp_master_poller": {

      "type": "repo_poller",

      "branch": "master",

      "repo_url": "https://weave.googlesource.com/weave",

    },

  },

but the bot isn't auto firing.  i'm guessing i need to add "/manifest" to the end of the url.

I'm not sure offhand, as I wasn't too involved in adding the repo_poller support. 

Hopefully nodir@ knows ...

I don't remember. Look at the ndk build config, it should give you an example (its manifest would be in blah/platform/manifest, so if it just says blah/platform then you don't need to append manifest).

[Daniel Jacques]

Repo poller (source is here) is initialized from builders.pyl here. It is a BuildBot poller that performs a "repo init" on the specified manifest and then periodically issues "repo sync" for a set branches and punts changes for the difference in all of the referenced repositories.

Looking at the code, it runs "repo init" against "<repo_url>/manifest", so I don't think "manifest" should be included.

From OP: "but the bot isn't auto firing". Are changes not being recorded (leftmost column on waterfall), or are builds just not being executed? If the problem is the latter, it's possible that the change filter that you are using isn't matching the changes that are being punted (e.g., mismatched repository, branch, etc.).

the libiota repo does have restrict ACLs, and the vast majority of CLs are going in there.  what acct does the poller run as so i can make sure it has access to the weave GoB ?

It uses the default Git master account. I'd ping the trooper and ask them to get you that info, am not at a terminal ATM.

If there were errors, they should be logged in the buildbot logs, so that's something to check as well.

[Mike Frysinger]

the buildbot itself can sync the repo ... i had a bug to get that to work :).  i assume the repo poller uses a different account from the buildbot though.

Yes, it's using the credentials on the master system.
