wohali opened a new pull request #654: Disable compaction daemon on eunit run couch startups
URL: https://github.com/apache/couchdb/pull/654
 
 
   Commit 21f9544 enabled the compaction daemon by default. And commit
   3afe3ad disabled the compaction daemon at the start of the compaction
   daemon tests. Unfortunately, the compaction daemon remains active
   during all the other EUnit tests.
   
   I attempted to override the [compactions] _default line in the file
   rel/files/eunit.ini but specifying `_default=` or `_default=[]` did not
   provide the desired behaviour.
   
   This change disables the _default config as part of
   `test_util:start_couch` after startup. This means there is a very
   brief period during which the daemon is running, but in empirical
   testing the only thing I've seen it manage to do is compact `_dbs`
   before being disabled.
   
   Tested with `make soak-eunit` for 3 hours; this seems to eliminate
   the `all_dbs_active` error we've been seeing in CI runs since the
   compaction daemon was enabled by default.
