Looking in ./Python/thread_pthread.h"
+252 #if defined(THREAD_STACK_SIZE)
+253 PyThreadState *tstate = _PyThreadState_GET();
+254 size_t stacksize = tstate ? tstate->interp->pythread_stacksize : 0;
+255 tss = (stacksize != 0) ? stacksize : THREAD_STACK_SIZE;
+256 if (tss != 0) {
+257 if (pthread_attr_setstacksize(&attrs, tss) != 0) {
+258 pthread_attr_destroy(&attrs);
+259 return PYTHREAD_INVALID_THREAD_ID;
+260 }
+261 }
+262 #endif
It appears asif the call needed (for AIX) - thread_attr_setstacksize(&attrs,
tss) should be occurring.
Can you help me with a quick program that reports back the actual stack size an
AIX thread has?
What may be at the heart of this (assuming the call above is working as
expected) - the default memory size for AIX 32-bit is 256MB. Assuming 16 to
32MB is already in use - if I understand this "recurse" logic - after about
12-14 recursions the 256MB is consumed.
In short (work calls) - it seems the API mentioned is already in place and what
is happening in terms of "exception catching" is different.
Looking forward to hints on how to dig further.
