 20 Nov 2009, Konstantin Olchanski, Bug Fix, fix odb corruption from too long client names
|
odb.c rev 4622 fixes ODB corruption by db_connect_database() if client_name is
too long. Also fixed is potential ODB corruption by too long key names in
db_create_key(). Problem kindly reported by Tim Nichols of T2K/ND280 experiment.

07 Sep 2009, Exaos Lee, Forum, deprecated conversion from string constant to ‘char*’ 
|
I encountered many warning while building MIDAS (svn r4556). Please see the
attached log file. Most of them are caused by type conversion from string to
"char*".

30 Oct 2009, Konstantin Olchanski, Release, new lazylogger release

I committed an updated lazylogger with updated documentation. The new version supports subruns and
can save to external storage arbitrary files (i.e. odb dump files). It also moves most book keeping out of
odb to permit handling more files on bigger storage disks.
