Thread deadlock activerecord 2.2.2/ruby 1.8.6/postgres win32


#1

Hello,

I’m trying to run the tests that come with activerecord-2.2.2. I’m using
PostgreSQL 8.3 with the pg driver. Other details:

ruby version: 1.8.6 build 111
platform: windows XP SP2
activerecord version: 2.2.2
activesupport version: 2.2.2
pg version: 0.7.9.2008.10.13
mocha version: 0.9.3

When I run "rake test_postgresql TEST=test\cases\transactions_test.rb, I
get a thread deadlock. The error output is attached.

Some other observations:

  • The error only manifests itself when the ruby environment platform is
    windows. The tests work perfectly under Linux (at least, with ruby 1.8.6
    build 114 rather than 111)
  • The platform of the PostgreSQL server machine is irrelevant to the
    test outcome.
  • Comparing database query logs of a (linux-based) good run with a
    (windows-based) bad run shows no relevant differences in the queries
    being sent to PostgreSQL, until the failure occurs where the windows log
    just stops abruptly.
  • The error isn’t the result of a database deadlock.

I also tried this with ruby 1.8.7. This doesn’t give a deadlock error -
instead it just hangs at the same point.

Any ideas on how to get these tests to run to completion successfully?

Thanks,

Charles D.
