I gave it a try, doesn't seem to be so simple.
I let valgrind generate the suppressions to get started. This is for
Ubuntu14.04:
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:calloc
obj:*
obj:*
obj:*
obj:*
obj:*
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
fun:actionPrepare
fun:processMsgMain
}
This is for CentOS 7:
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:malloc
obj:*
obj:*
obj:*
obj:*
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
fun:actionPrepare
fun:processMsgMain
fun:doSubmitToActionQ
}
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:malloc
obj:*
obj:*
obj:*
obj:*
obj:*
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
fun:actionPrepare
fun:processMsgMain
}{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:calloc
obj:*
obj:*
obj:*
obj:*
obj:*
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
fun:actionPrepare
fun:processMsgMain
}
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:malloc
obj:*
obj:*
obj:*
fun:pthread_once
obj:*
obj:*
obj:*
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
}
[I missed one violation here, but that doesn't really matter for the
context].
So it's quite different. I now thought I check if I misunderstood the
format and I can skip some of the contents. So on CentOS I changed
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:malloc
obj:*
obj:*
obj:*
fun:pthread_once
obj:*
obj:*
obj:*
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
}
to
{
<insert_a_suppression_name_here>
Memcheck:Leak
match-leak-kinds: definite
fun:malloc
obj:*
obj:*
obj:*
fun:pthread_once
obj:*
fun:dbi_conn_connect
fun:initConn
fun:beginTransaction
}
... and the error shows up again.
Anything that I should change?
