I noticed Andreas Koenig opened a bug report on Inline (RT#85336) wherein he asserts there's probably a race condition present, as he's finding that operating several smokers in parallel will sometimes result in failures.
This may be related to an issue I see, where running Inline::CPP's test suite with HARNESS_OPTIONS=j9 will also result in failures. Inline::CPP's tests are not sensitive to script order (tests within a script must be run in order, but it shouldn't matter what order the test scripts are run). As they're not order-sensitive, failure under harness parallel testing has to point to a race condition within Inline::CPP or Inline. I'm going to look over Inline::CPP's code base with added scrutiny to assure that any IO operations it owns are implementing flocking. But it doesn't own many IO operations; most IO is pushed off to Inline, or the compilers themselves. One area I hadn't previously considered is Makefile.PL itself, which opens a file for output. That should be fine under normal user conditions, but could present a problem for smokers running in parallel. Dave -- David Oswald daosw...@gmail.com
