Recently, we added information schema support to Google’s userstats patch.
There are three information schema tables added: user_statistics, table_statistics, index_statistics.
One can now use select * from information_schema.user_statistics along with show user_statistics.

Could you guys update Mark’s bug with these please?
http://bugs.mysql.com/bug.php?id=31719
Would you also be interested in having this included in the main line server, and be willing to sign a CLA for this? I’d love to see these included myself, and am willing to advocate them internally.
This is great. Is there a bzr patch for this? I want to port it back to the Google patch.
Funny. I just noticed the link above for 5.0.62 is a patch.
‘@Mark – Can someone pay for an independent legal analysis of the MySQL CLA? It is a large legal document.
2 Mark Leith,
I personally would like to see it included in MySQL, but CLA seems problematic.
Our patch is GPL and based on Mark Callaghan’s patch, which also GPL. I think that enough to include in GPL version of MySQL.
‘@Vadim Tkachenko – The feature request for this claims it will be in the official release for 6.0.
Vadim – there is no problem for US to release it as GPL however this will not be enough for inclusion in stock MySQL. In Drizzle… it should be enough.
Peter
I understand GPL difference.
I share the concerns about CLA with Baron, Mark Callaghan and Paul Paul McCullagh http://groups.google.com/group/oursql-sources/browse_thread/thread/1662e1d4d4fadc71?hl=en#
Actually, here’s my REAL opinion about the CLA:

Hey I’m just a lowly Support guy, it seems that you guys are having a good discussion about this with Jay however, and he’s probably the best person to be dealing with on the issues of community contributor agreements.
However, from *my* perspective, I would love to see this work included within MySQL, I think it would benefit a lot of people, and deserves to be distributed to the masses rather than the few.
I’ve raised some more awareness internally for these patches however, and people are interested in them. I hope that we can all come to some better agreement on how to include this (and other) work!
If anyone needs it I’ve rediffed this against 5.0.66a (bzr revno 2631.4.4) and included 3 more minor patches to the test suite .result files so the build cleanly passes the test suite. No code changes at all.

Matthew,
What problem with test suite did you have ?
Hi Vadim, I’ve broken out the test suite stuff here
http://magoazul.com/tmp/userstats-is-5.0.66a-testsuite.patch
those 3 tests were failing.
also noticing a funny parser issue trying to query the unquoted table name
mysql> use information_schema;
Database changed
mysql> select count(*) from table_statisticsG
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual

1 row in set (0.00 sec)
mysql> select count(*) from `table_statistics`G
*************************** 1. row ***************************
count(*): 269
1 row in set (0.00 sec)
other than that it works great. thanks to all who contributed.
Matthew,
Thanks, will look into that.
Any patch to patch 🙂 or more official patch against v 5.0.67 ? Thanks
