Subject Re: Accessing the SVN log from java Code
Date Tue, 17 Apr 2012 19:22:48 GMT
Hello Andy, 


Thanks for the quick reply. We are also not bothered with the checkouts. We are only bothered
about the check-ins & we will also have similar DB setup. But we will do a nightly refresh
of the data in DB by pulling the log data from the svn repository. 


However, the point of this post is the Java Code. I am not sure how I can "look up" the svn
repository from the code. Was hoping if a good Samaritan would help out with a code snippet. 

Also, I am unsure who Ryan Schmidt is & how do I get in touch with him. 


Thanks. 
AJ

The repository doesn't keep track of checkouts, so you cannot glean
that data from the repository. Ryan Schmidt has a script that can be
used to parse Apache logs to collect this information.

I would recommend against pulling this data from the log in realtime,
but instead populate a database with the relevant data (you'll have to
write something to do this for an initial population of the database
using a one-time output of svn log, then have a post-commit hook which
updates the database going forward), and generate your reports from
queries against that database. The only instance where this would
become a problem is if you regularly change revision properties, but
you can have a post-revprop-change hook to perform those updates if
needed.

Although I don't use it to retrieve/parse log entries, I use SVNKit to
interrogate my repository from within Java. http://svnkit.com/
