now mysql_server_init is called from mysql_init with fake parameters
mysql_once_init code included to mysql_server_init.
embedded-specific initialization is in init_embedded_server function
more general message when slave can't start because of incorrect
replication information, the previous one was sometimes a misleading
indication (i.e. sometimes the problem had nothing to do with
system permissions).
The perfect fix would be to report the exact error to the client
(instead of pointing the client to the error log); this is a bit
of work so it's more a development task:
WL#1088 "Move all hardcoded messages of replication to share/errmsg.txt".
I was not able to modify the errmsg.txt in these sql/ subdirectories:
danish
dutch
german
italian
portuguese
russian
spanish
swedish
ukrainian
"EE_ error codes (EE_DELETE, EE_WRITE) end up in the binlog, making slave stop".
The problem was that during execution of the command on the master, an error
can occur (for example, not space left on device, then mysqld waits and when
there is space it completes successfully: so finally it worked but the error
EE_WRITE remains in thd->net.last_errno and thd->net.last_error).
To know if finally the command succeeded, we test the 'error' variable in
every place, and if it shows no failure we reset thd->net.last_err* using
the function THD::clear_error() which is backported from 4.1.
A new test to see if now only real errors get to the binlog (note: the test
uses "rm").
Also a bit of memory free/alloc saving in log_event.cc (do not free the whole
mem_root after every query in the slave SQL thread: we can keep the initial
block of it; which will be freed when the thread terminates).
command delimiter to change the default delimiter (;) to something
else, a string upto 16 characters is allowed. Separate the sub
queries with ';' and end the whole statement with your own delimiter.
Signed auto_increment keys for HASH tables (like for MyISAM tables in 4.0)
