Assertion failure for libmysqld on Tru64
am 09.10.2002 23:13:16 von Randall Severy
How-To-Repeat:
Ever since MySQL 4.0.1 was released I've been trying to build a
working libmysqld embedded MySQL library on the Compaq Tru64 (formerly Dec
OSF) platform. With each successive bugfix release I've tried again, and
just did with 4.0.4, but each time I run into a problem with the error
handling that causes a core dump when a database error occurs that
generates the following failed assertion:
Assertion failed: vio->packets, file lib_vio.c, line 118
The stack trace from the latest test is as follows:

I have posted messages about this problem to mysql@lists.mysql.com
several times during the spring and summer, and had a detailed conversation
with Dan Nelson on that list in August that helped isolate the specific
problem, but no one has been able to identify a solution to the problem.

Have you tried if the test programs in libmysqld/examples compiles and
works on your machine ?
Do you have a test program that shows this behaviour that you could
share with us so that we can try to repeat this ?
Another option is if you could let us login to your system and try to
debug this.
The assert in lib_vio.c indicates that something strange is going on,
but it doesn't tell us what it could be and how to fix this.

Does the above table exists ?
There could be some bug in the error handling for the embedded library
that we are not aware of...

Monty,
I'll see if I can duplicate the problem with one of the test programs
in libmysqld/examples.

No, the above table does not exist. Both times I have received the
assertion failed error it has occurred during the error handling in the
embedded library, so your guess may be correct.

Monty,
Here is the shortest test program I could come up with that
duplicates the problem:
------------------------------------------------------------ -------------------
/*
testmysqld.c - Test program to duplicate assertion error on Tru64
Written 2002 Randall Severy, CyberTeams, Inc.
*/
#include
#include
#include
#include "mysql.h"
static MYSQL connect_socket;
int main(int argc,char **argv)
{
MYSQL *db_socket;
char *init_args[3] = {"","--datadir=./db","--language=."};
mysql_server_init(3,init_args,NULL);
db_socket = mysql_real_connect(&connect_socket,NULL,NULL,NULL,
"testdb",0,NULL,0);
mysql_query(db_socket,"drop table test");
mysql_close(db_socket);
mysql_server_end();
return(0);
}
------------------------------------------------------------ -------------------
The output from this test program is the same as the original program
(Assertion failed: vio->packets, file lib_vio.c, line 118). The "test"
table used in the above example does not exist. The test program never
gets past the "mysql_query" call. Interestingly enough, in setting up this
test I found that if the directory specified by "datadir" does not exist
that the test program crashes with a seg fault error.
>Another option is if you could let us login to your system and try to

I'm doing this testing on one of Compaq's Tru64 "Test Drive"
servers. If you need to get in there to debug this I can send you the
login information.

Holyfoot is in charge of this problem.
HF, could you describe the current status, please?
