Bitten should not overload the Trac DB with SVN checkout information

[Emmanuel Blot <manu.blot@…>]

See initial discussion here: ​http://groups.google.com/group/bitten/browse_thread/thread/67ff1e98079bdd67

Bitten generates thousands of useless log messages when the SVN checkout recipe is run.

It is related to #267 as well, as it is the root cause of the slow page generation.

Proposal to provide a stdout custom filter

[Emmanuel Blot <manu.blot@…>]

I've added a quick patch to filter out the messages from the executable standard output.

The filter is disabled for any command, except for SVN checkout where it discards the typical "Add" or "Update" log messages output from the SVN checkout command.

The original behavior (loads of the "A path/..." log message) can be restored if the SVN checkout build recipe specify verbose="True" argument.

Note

the --quiet option of SVN could be used (triggered from the SVN recipe) rather than filtering the output message, however the slave won't print out the SVN messages at all, which can still be useful on the slave side. The proposed patch provide a more versatile way to filter out output messages on a per-recipe basis.
