Everything goes very smooth, except that I found out: - in every call to my module handler the system allocated memory will not be free. - ex: I'm using libapreq in my code to receive a request, and upload file. every upload file, my system have to allocate a chunk of memory and never free it. - I tried to use subpool ap_make_sub_pool() out of r->pool and destroy it as soon as I finish. I call ap_bytes_in_pool() and see the same size as before and after ap_destroy_pool - I digged into alloc.c and found the defined tag: #define ALLOC_USE_MALLOC. wow, after compile the apache with this define the memory is free automatically. I don't even have to destroy it.
question: - why is that? problem: - in my module, some handler will fail with ALLOC_USE_MALLOC I appologize if I bring up such a stupid problem. If so, please point out for what I should do to free up the memory when using pool Thanks Thu Nguyen >How-To-Repeat: -create a module with handler to open a file, save everything in the buffer created by ap_pcalloc() - monitor your system allocated memory and see it goes up and never back down. >Fix: ALLOC_USE_MALLOC seem to do the trick but cause other problems... wells, is there others? >Release-Note: >Audit-Trail: >Unformatted: [In order for any reply to be added to the PR database, you need] [to include <[EMAIL PROTECTED]> in the Cc line and make sure the] [subject line starts with the report component and number, with ] [or without any 'Re:' prefixes (such as "general/1098:" or ] ["Re: general/1098:").
