Eric,

try using the mysqlbinlog program from some other version, maybe 4.0.0, or
3.23.xx.

I noticed a similar bug a while ago. mysqlbinlog seg faulted on a binlog
file.

I am forwarding this bug report to our replication expert.

Best regards,

Heikki

Hi,

I deleted a db I didn't mean to.  I am using mysql 4.0.1 Alpha and some
innodb and some myisam tables.
I have the log files I need to restore my data since I have been running
since the last backup with binlog enabled in my.cnf.

The problem is that mysqlbinlog shows some log files, but other log files
choke.

In VI I can see this at the top of one of one log file:

but mysqlbinlog only shows this for this 4.8M file:

root@www194:/home/back# mysqlbinlog www194-bin.001
# at 4
#020611 11:17:06 server id  1   Start: binlog v 1, server v  created 691231

# at 73

use ;
LOAD DATA INFILE ''  REPLACE INTO TABLE nsitille  OPTIONALLY  ENCLOSED BY
'\0' ESCAPED BY '\0' LINES STARTING BY '\0';



I had been running this machine as a Master to a remote slave. And some of
the logs are large because I ran LOAD DATA FROM MASTER a few times from the
slave machine.  So I have the data I need but I can't access it. I have a
total of 8 log files, only two work with mysqlbinlog. The rest return very
shortly like above.

This is really freaking me out, if this doesn't work, then I will have to
start not trusting the log at all, which would suck. I have been able to
restore data before, in the same way, from this same database and config.


Thanks,


Eric
