#2222 dustin master-side git step doesn't support reference repos. comment 10:33:18

Yes, thanks for the reminder!

#2222 dustin master-side git step doesn't support reference repos. description 10:33:18

The slave-side git source step takes a reference argument that points to a git repository from which git should fetch objects. That option causes git clone to be called with --reference $ref, and later adds $ref/objects to the new repository's .git/objects/info/alternates.

The master-side git source step should have the same functionality.

#2461 juj Add support for providing and graphing data charts of build statistics over time. comment 07:53:11

I have recently added this feature into MathGeoLib?, see here:

 http://clb.demon.fi:8113/waterfall  http://clb.demon.fi/dump/MathGeoLib_testresults/index.html?revision=4ff29c9d3537071c9a8ad81e4425bceb2fccb7fc

How does it work?

  1. Each build slave builds a test executable as part of its build.
  2. The test executable is programmed to output a test results JSON file to local disk. See an example:  http://clb.demon.fi/dump/MathGeoLib_testresults/e8287b43e7e9d416f2d0771889d856212af8e7f3-vs2012-32bit-sse41.json
  3. A FileUpload? step is performed to upload this to WWW server. The WWW server stores all .json result files across time in a single web-accessible folder.
  4. A custom WWW page was created ( http://clb.demon.fi/dump/MathGeoLib_testresults/index.html) that
    1. is given a HTTP GET parameter of where to locate the JSON results files.
    2. loads all JSON files (by git revision hash) using jQuery.
    3. assembles the loaded JSON data into a format displayable using HighCharts?.
    4. Outputs results graph to user.

I see that anyone looking to integrate this to their own project will need to perform similar kind of custom results file creation process via their application, to be able to graph custom data.

This whole process is very specific to MathGeoLib?. I see a lot of room for further work:

  • Generalize the machinery to that it is useful for other domains, open questions:
    • Should the results JSON file format be 'standardized' on?
    • What other types of graphs would be useful?
  • Simplify the machinery that it's easier to integrate to new projects.
  • Integrate the graph rendering page to waterfall.
  • Add support for drawing graphs for changes over time. The current page draws data only for a single git commit hash.
  • Add support for drawing graphs from internal data produced by Buildbot. By internal data I mean e.g. the properties produced by build steps. Example:  http://clb.demon.fi:8113/builders/vs2012-MathGeoLib-32bit-SSE4.1/builds/24 One might want to graph time elapsed in the build step, and how it varies across time. Users can also defined properties, and there are properties specific to certain steps, like the "warnings-count" on the example page.

There is a JSON API to buildbot to retrieve these properties, so perhaps that would be a starting point.

On a very high-level scale, I see there being two types of data: build properties that are automatically produced by BuildBot steps, and custom data that's internal to the project and possibly very domain-specific, like the profiling data generated by MathGeoLib?.

Graphing buildbot-generated data should be super-easy (could be automatic even without user configuration needed?), but graphing project-generated data will definitely require a custom procedure like the one developed as a proof-of-concept above.

#2499 dustin PBChangeSource doesn't drop changes when no files start with `prefix` comment 06:00:22

Rather than change behavior (because many users use PBChangeSource with no changes), we should alter the docs.

I think that this occurred a while back when we changed things so that a 'buildbot sendchange' without any files would succeed.

#2454 dustin SiGHUP doesn't always work comment 18:47:45

I don't mean that you're seeing things different from the *expected* behavior of the code - I mean that you're seeing things that indicate you're running different code than I'm looking at, which makes this impossible to diagnose. Your system behaves *radically* differently from any other user's, and we need to find the reason for that. You've been feeding me interesting tidbits, but ultimately it's up to you to find out what makes your system different from everyone else's, and either fix that or describe the difference so that we can adjust Buildbot to accomodate.

You do have two copies - three, in fact - of the code installed. You've pasted a copy of them in the previous comment. I'd suggest deliberately introducing a syntax error in the "wrong" eventual.py as a way of checking that it's not being run.

The SIGHUP handler calls eventually, which prints a message to twistd.log. So either the signal isn't being delivered, or the handler isn't logging, or you're looking in the wrong twistd.log.

This bug isn't particularly actionable for us as Buildbot developers until you can narrow down exactly what's going on. This may be a bug in Buildbot, but it may not. That's going to take some serious detective work from you.

#2454 virgilg SiGHUP doesn't always work comment 18:07:09

your Buildbot is behaving in ways contrary to what the code says.

I don't think I would be opening a bug if the code would do what it should :-)

The debugging code should definitely show up.

It doesn't. Am I looking in the right place (twistd.log)? How about the strace and the hanging in the xstat64 I provided? Couldn't those happen _before_ they reach that code? (I said I hit this during e.g. a reconfigure - that code could simply have not run yet)

That suggests that maybe you have multiple copies of the code on your system (assuming you've restarted the master since making that change).

No, I don't have multiple copies. And yes, I've restarted the master (obviously).

The id's are generated by the http push code - they're not seen elsewhere in Buildbot.

We've been going back and forth on this for quite a while now, and nothing really makes sense from here - your Buildbot is behaving in ways contrary to what the code says. I think someone with a knowledge of Buildbot needs to actually login to your systems and have a look around. I don't necessarily have time, but asking in irc or on the mailing list might bring success.

#2454 virgilg SiGHUP doesn't always work comment 11:16:14

Hmm, this looks odd (though perhaps unrelated):

Why is the started state this old? Where is 225108 and how can I find what it is?

#2454 virgilg SiGHUP doesn't always work comment 11:13:00

Did you try adding the debugging code in comment 3? That would help to narrow this down.

Oh, forgot to mention that. twistd.log has no hits for the debug print code you mentioned. I added that code long time ago, seems like there is a path that never hits it in this scenario.

#2454 dustin SiGHUP doesn't always work description 15:16:13

Every now and then on 0.8.5 and more often on 0.8.7p1 we see at reconfigure time: sending SIGHUP to process 41208 Never saw reconfiguration finish.

The fix is generally to restart the master, but the problem with this approach is it's going to stop everybody else's builds from happening (we get slaves lost due to the time it takes to reconfigure - way less than the 10 minutes timeout, but we lose them still).

Doing $ kill -SIGHUP 41208 doesn't produce anything in twistd.log, so it appears to be indeed stuck.

How can we make this rock-solid?

#2489 dustin Events getting repeatedly pushed via httpstatus comment 14:57:14

Ah, yes, I bet it is re-susbcribing to events on reconfig, but not unsubscribing.

If there's a fix for this in 0.8.x, I'm happy to merge it, but this code is going away in 0.9.x, which is where my efforts are focused.

#2454 virgilg SiGHUP doesn't always work comment 22:14:04

I installed the same buildbot instance on Linux (creating my own Debian packages from 0.8.7-p1). If it's the same problem, I was able to reproduce by reconfiguring in the midst of reconfiguring (i.e. while reconfigure is happening, trigger another reconfigure).

On OS X I have a wrapper script that locks the reconfigure process, so that people cannot trigger more than one at the same time, but even so, when reconfigure is "done", it takes additional time for the submittal factory to start up. I think that if they happen to reconfigure during one of those factory startup times (that happen at various time intervals, not only immediately after a reconfigure) then they will botch the current buildmaster instance in a similar way.

Nothing. Finally killed.

Therefore the problem appears to be in the submittal code and unrelated to something specific to Python on OS X. This confirms my hypothesis that other colleagues using buildbot on OS X but not using the submit code did not see this.

#2489 jachen Events getting repeatedly pushed via httpstatus comment 09:25:13

It seems the longer the buildbot master stays up, the more duplicated events there are. I am not sure if running 'buildbot reconfig .' a bunch while the builders are running is also a contributing factor of these duplicates.
