[syslog-ng] commit with the oracle sql driver

[Patrick H.]

Followup. I finished adding flush_lines and flush_timeout to the sql 
driver. They do what you'd expect, a commit after X number of lines or X 
seconds.
I also fixed a bug that was causing a "." (dot) in the table name to be 
replaced by an underscore (dots are fully valid in oracle as they denote 
schema-table separation).
I'm starting on converting the code over to using bind variables as 
well. The performance difference between plain text queries and prepared 
statements is very large. Especially since we'll be doing hundreds of 
inserts per second.

One of the users in the IRC channel suggested I ask about any licensing 
issues. Not sure what exactly since the syslog-ng code is GPL, but 
figured I'd ask anyway.
If all is kosher, once all my changes are complete, I can send a patch file.
