Don't use APR_POOL_DEBUG
Hi,
Please don't use APR_POOL_DEBUG today.
There is a logic error* in there which I will fix
tomorrow. Thanks for your patience.

aborts on correct usage.

I've tried worker with the latest apr_pools.c. As long as I only have
one concurrent HTTP request it appears to work great :)
With both the plain APR_POOL_DEBUG as well as APR_POOL_DEBUG_VERBOSE
it deadlocks when I have more than one concurrent request.
This is on Solaris.

APR_POOL_DEBUG is functioning again WAS: RE: Don't use APR_POOL_DEBUG
Posted by Sander Striker <st...@apache.org>.
Hi,
As of a recent commit the apr pools debug code is
functioning again. I tested it with httpd-2.0 HEAD
and it works (both tried worker and prefork to see
if everything goes to the log ok).
Some hints (that probably change when we move to
a numbered system for selecting the debug mode):
If you want a debug build:
$ CPPFLAGS=-DAPR_POOL_DEBUG ./configure ...
$ make
If you want a verbose debug build:
$ CPPFLAGS=-DAPR_POOL_DEBUG_VERBOSE ./configure ...
$ make
When switching between verbose and regular, only
recompile apr_pools.c and relink:
$ rm srclib/apr/memory/unix/apr_pools.o
$ CPPFLAGS=-DAPR_POOL_DEBUG_VERBOSE make
A tip on starting the server (when verbose debug is on):
# cd <where httpd is installed>
# bin/httpd 2>>logs/error_log
This will put all of the debug output in the log,
even the start of the server (at which time the
log isn't opened, but pools are being created).
