6f3cf907b8 Readability patch: ERRVAL() macro for pthreads < 7 vs. >= 7 return values. 2007-05-18 15:28:09 +00:00

e509d3ed9a Comment fixes.
Corrected rev 1.67 cvs comment: ltu_key[] is NULL-terminated _when not full_.

810b2389dc Since we only have LDAP_MAXTHR thread_keys, allow max LDAP_MAXTHR
threads per pool, even when ltp_max_count <= 0 ("unlimited").
Keep ltp_max_count in range [0, LDAP_MAXTHR].

f0a1511422 Make ldap_int_thread_userctx_t.ltu_key[] a proper NULL-terminated array.
(setkey/getkey expected that, but purgekey could set a NULL in the middle.)
Added some checks for input key!=NULL.

API changes, need review - I'm not sure what's indented here:
- setkey(data=NULL, kfree!=NULL) searched as if intended to reset
  the key, but updated by setting the key.  Now always updates.
- setkey(key=<not found>, data=NULL) could return either success or
  failure.  Now succeeds iff (data == NULL && kfree == NULL).

f5da908c49 thread_keys is a (poor) open-addessed hash table, but it lacked a
"deleted item" mark.  Add DELETED_THREAD_CTX.
Also improve the hash function a bit, and make the hash unsigned.

8a92825225 Protect thread_keys[] with ldap_pvt_thread_pool_mutex, except in
ldap_pvt_thread_pool_purgekey() which may only be called during pauses.

Thus, also wait for pauses to finish before accessing thread_keys in
ldap_int_thread_pool_wrapper().  This may prevent pending tasks from
being started when a pause had been requested, which seems to have been
possible.  If that was a feature, we can split ltp_pause==1 in 2 states:
in pause (causes wait), and pause requested.

Also move 'thread_keys[].id = <thread id>' from pool_submit to
pool_wrapper.  Until pool_wrapper set the ctx as well, thread context
lookup would just return NULL anyway.

92afeb8ef7 Replace state LDAP_INT_THREAD_POOL_PAUSING with member ltp_pause,
so a pause will work during states FINISHING and STOPPING.

Add missing waits and signals, and move waits in pool_wrapper().
Replace if(test) with while(test) when waiting for the multi-purpose
condition variable ltp_cond.

9e9bf22a64 ITS#4943:
In ldap_pvt_thread_pool_submit(), when backing out of thread creation:
  ltp_pending_count '++' -> '--'.  Signal if there are no more threads.
In ldap_int_thread_pool_wrapper():
  if() -> assert() where false would result in eternal loop.

123948bd5e Add thread debugging wrapper thr_debug.c and ldap_thr_debug.h in libldap_r/,
enabled with LDAP_THREAD_DEBUG (cpp macro and environment variable):

Move any ldap_pvt_* definitions from ldap_int_thread.h to ldap_pvt_thread.h.
#define ldap_int_thread_equal/ldap_pvt_thread_equal instead of tpool.c:TID_EQ.
Define some ldap_debug_*_t types, and LDAP_UINTPTR_T, in ldap_int_thread.h.
ldap_int_thread.h/ldap_pvt_thread.h can now be included multiple times, giving
different results depending on whether libldap_r/ldap_thr_debug.h was included.
Add some cleanup and some preprocessor hacks.
#define LDAP_THREAD*_IMPLEMENTATION in libldap_r/*.c, used by ldap_thr_debug.h.
Add PTHREAD_MUTEX_ERRORCHECK/PTHREAD_MUTEX_ERRORCHECK_NP in thr_posix.c.
