I recommend you to check apr_allocator_max_free_set().
The following sample code shows the effect.
Without calling apr_allocator_max_free_set(), you can find the memory usage is
growing rapidly.
///////////////// sample code starts
/* memory pool leak test.
* @remark No error checks */
#include <stdio.h>
#include <apr_general.h>
int main(int argc, char **argv)
{
apr_pool_t *mp;
int i;
apr_initialize();
apr_pool_create(&mp, NULL);
/* XXX Without this setting, memory usage is growing more than expected */
#define MY_POOL_MAX_FREE_SIZE 32
{
apr_allocator_t *pa = apr_pool_allocator_get(mp);
if (pa) {
apr_allocator_max_free_set(pa, MY_POOL_MAX_FREE_SIZE);
}
}
#define BASE_ALLOC_SIZE (8*1024)
i = 0;
while (1) {
apr_palloc(mp, BASE_ALLOC_SIZE + i);
i++;
if (i % 10000 == 0) {
puts("press enter key (please check memory usage)");
getchar();
}
apr_pool_clear(mp);
}
apr_terminate();
return 0;
}
///////////////// sample code ends
