Hello!
I'm using valgrind for a long time, and usually I'm able to fix all
warnings. But for a long time I have problem with conflict between
syslog and PQexec.
When I'm calling syslog in one thread, and PQexec in another, helgrind
screams:
==2571== Possible data race during write of size 4 at 0xa0fdaf0 by
thread #11
==2571== at 0x4069015: ??? (in /usr/lib/libpq.so.5.2)
==2571== by 0x40696C0: ??? (in /usr/lib/libpq.so.5.2)
==2571== by 0x4060839: ??? (in /usr/lib/libpq.so.5.2)
==2571== by 0x405F655: PQgetResult (in /usr/lib/libpq.so.5.2)
==2571== by 0x405F91F: ??? (in /usr/lib/libpq.so.5.2)
.....
==2571== This conflicts with a previous write of size 4 by thread #10
==2571== at 0x42AA028: __vsyslog_chk (syslog.c:217)
==2571== by 0x42AA4C6: syslog (syslog.c:119)
.....
The application works fine, but I'd like to know how to fix it.
I know, that I can create mutex for syslog and PQexec, but it seems
strange...
best regards
Jarek
