1024 limits??
Hi,
Im building a server that uses libpq to connect to a database and
authenticate the users that connect.
I do PQfinish for the conn and PQclear for the result so there cant be
a memory leak there.
If I remove the function where I authenticate my server can handle as
much clients as I want.
If I authenticate every clients with connections to the database it
crashes on PQconnectdb at th 1024th client without returning an error(it just
segfaults).
My ulimit -n is more than 1024 btw.
Did anybody encounter such problem?? I've been trying to fix this one
for a long time...
Thanks
-Mat

Which authentication method do you use?

Please provide a backtrace from the segfault ...

I just do a select on a user table with the username and password
pretty upfront and normal query
you would like me to use PQtrace???
it doesnt say much
if I do bt on gdb it says: 0x4b3003d in ?? ()

Im currently using rpms
is there a way to just remove an rpm(the API one) and compile only that??
where can I find libpq sources?
my app is already compiled with -g

You'll need to recompile libpq and your application with -g in CFLAGS
to get a more useful backtrace from gdb.regards, tom lane

You need to compile PostgreSQL from source with -g ..
ftp.postgresql.org is the main FTP, there are many mirrors. Look for the
source tarball there..

If you don't want to mess with removing the RPMs, you don't have to.
Build the source with -g, but don't install it. Instead, copy the
static libpq.a library (look in src/interfaces/libpq after building)
to your application directory, and force your app to link against it
instead of against the libpq.so that's in /usr/lib (or whereever the
RPMs installed it).
regards, tom lane
cc -o therver therver.c -g -lflipr -lpq -L. -lpthread -D_REENTRANT
./libpq.a(fe-auth.o): In function `pg_password_sendauth':
/usr/local/postgresql-7.0.3/src/interfaces/libpq/fe-auth.c:465: undefined reference to `crypt'
collect2: ld returned 1 exit status
make: *** [therver] Error 1
this is what I get
should I copy other files?

no, just add -lcrypt to your LDFLAGS
Which file should I read the symbol from??
