Subject: is libpq thread safe without configure enable_thread_safety=yes
Date: Thu, 25 Oct 2007 14:15:45 -0700 (PDT)
Message-ID: <731502.39043.qm@web37301.mail.mud.yahoo.com> (raw)
I want to use the libpq in a multithreaded process. I intend to use two
different connections for two different threads. The requests and results
for each connection will be handled completely by each thread independently.
I tried to set enable_thread_safety and enable_thread_safety_force to yes.
However, the compile fails because of references to pthread routines which are not
supported by my os. Specifically:
../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_sigmask'
../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_mutex_unlock'
../../../src/interfaces/libpq/libpq.so: undefined reference to `pthread_mutex_lock'
../../../src/interfaces/libpq/libpq.so: undefined reference to `sigwait'
I can change the code to fix this, but I wondering if based on my application it is okay
to just configure without setting enable_thread_safety.
Thanks for any help.
Andrew
