I’m trying to speed up my builds some and was looking for some thoughts

  • 0

I’m trying to speed up my builds some and was looking for some thoughts on how to do so. I currently use Hudson as a continuous integration server for a PHP project.

I use an Ant build.xml file to do the build, using a file similar to Sebastian Bergmann’s php-hudson-template. At the moment, though (due to some weird problems with Hudson crashing otherwise), I’m only running phpDocumentor, phpcpd, and phpUnit. phpUnit does generate Clover code-coverage reports, too.

Here are some possible bottlenecks:

  1. phpDocumentor: Takes 180 seconds. There are some large included libraries in my project, such as awsninja, DirectedEdge, oauthsimple, and phpMailer. I’m not sure that I really need to be developing documentation for these. I’m also not sure how to ignore whole subdirectories using my build.xml file.
  2. phpUnit: Takes 120 seconds. This is the only portion of the build that’s not run as a parallelTask. The more tests that get written, the longer this time will increase. Really not sure what to do about this, aside from maybe running multiple Hudson build slaves and doling out separate test suites to each slave. But I also have no idea how to go about that, either.
  3. phpcpd: Takes 97 seconds. I’m sure that I can eliminate some parsing and conversion time by ignoring those included libraries. Not sure how to do this in my build.xml file.
  4. My server: Right now I’m using a single Linode server. It seems to get pretty taxed by the whole process.

Any other possible bottlenecks you can think of I’ll add to the list.

What are some solutions for reducing my build time?

    I’m not a PHP expert at all, but you ought to be able to split your PHPUnit tests onto multiple Hudson slaves if you need to. I would just split your test suite up and run each subset as a separate, parallel Hudson job. If you have a machine with multiple CPUs / cores you can run multiple slaves on it.

    One obvious thing you didn’t mention – how about just upgrading your hardware, or taking a look at what else is running on the Hudson host and possibly taking up resources ?
