Comment #11 on issue 12396 by [email protected]: Use system default stack
size for worker thread
http://code.google.com/p/chromium/issues/detail?id=12396
We found that the default stack size on Ubuntu 8.04 is 8 MB, which is much
bigger than I thought (1 MB or 512 KB). Although I still think it is fine
to use the default stack size (there must be a reason it's the default),
it's a lot of work to explain and prove that's the case, so I'm marking this
bug WontFix.
Here are the two methods we used to get the default stack size.
w...@aes:~/tmp$ ulimit -s
8192
w...@aes:~/tmp$ cat stack_size.c
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
int main() {
pthread_attr_t attr;
int rv;
size_t stack_size;
rv = pthread_attr_init(&attr);
if (rv != 0) {
fprintf(stderr, "pthread_attr_init failed: %d\n", rv);
exit(1);
}
rv = pthread_attr_getstacksize(&attr, &stack_size);
if (rv != 0) {
fprintf(stderr, "pthread_attr_getstacksize failed: %d\n", rv);
exit(1);
}
printf("default stack size %lu, or %lu KB\n",
(unsigned long)stack_size,
(unsigned long)stack_size / 1024);
return 0;
}
w...@aes:~/tmp$ gcc -m32 -pthread stack_size.c
w...@aes:~/tmp$ ./a.out
default stack size 8388608, or 8192 KB
w...@aes:~/tmp$ gcc -m64 -pthread stack_size.c
w...@aes:~/tmp$ ./a.out
default stack size 8388608, or 8192 KB
