DO JDBC query logging differences causes spec failure w/dm-core

Reported by Dan Kubb (dkubb) | July 19th, 2009 @ 01:17 AM | in 0.10.0

When DO is used with JRuby, the logging output is different for queries than when DO is used with MRI. This causes some spec failures in dm-core, since it compares the logged query with the expected query. Here is the specific failure as shown in the (new) CI system:


There are two problems:

  • The prepared statement object is being stringified, rather than the actual query with the bind values merged.
  • The query time is not being logged. The number of seconds should be displayed in as high resolution as possible. The current MRI driver shows as many as 6 digits after the decimal point. This is very useful for debugging and identifying slow queries for indexing/optimizations.

From what I can tell the query time not being logged occurs with all queries, while the prepared statement stringification happens only in specific cases.
