Happy New Year

ITS#6625 concurrency patch cleanup

happy belated New Year

Add ldap_pvt_thread_pool_retract() to cancel pending threads

Update copyright notices

ITS#5824: #if/#elif issues in thread #includes

ITS#5407 more checks for pool pausing

ITS#5364, thread pool efficiency:
Add ldap_pvt_thread_pool_pausing(): pause check for slapd without locking.

Happy New Year (belated)

rename ldap_pvt_thread_pool_setkey_x() to ldap_pvt_thread_pool_setkey() (as part of ITS#5309)

new ldap_pvt_thread_pool_setkey API

Added native thread-specific data support

ITS#4188 check for pool pause every 64 entries. (probably should make
this number tunable.)

For ITS#4943: Axe thread pool semaphore code

Wrap enum in #ifndef LDAP_PVT_THREAD_H_DONE; this code can be read twice.

happy new year

monitor __ALL__ thread parameters

Add ldap_pvt_thread_pool_tid()

Fix typo in comment

rmutex_lock etc.: caller supplies thread id

Added recursive mutex implementation

allow mutex ownership detection (thanks to Hallvard)

Happy new year!

silence SLAP_SEM_LOAD_CONTROL related warnings...

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.

ITS#3961 better fix - provide a context for the main thread. The context
must be reset by the caller to clear out temp allocations etc.

ITS#3961 provide ldap_pvt_thread_pool_fake_context_init/destroy, don't
use arbitrary context pointers.

Add ldap_pvt_thread_pool_purgekey to free all instances of key across
all threads.

Fix LDAP_PVT_THREAD_STACK_SIZE, automatically scale up on 64 bit machines

Added ldap_pvt_thread_pool_pause/resume

Happy New Year!

Happy new year

Updated notices and acknowledgements

New ldap_pvt_thread_pool_context()

Added ldap_pvt_thread_self() and ldap_pvt_thread_pool_context() API.

Happy new year

Bumped stack size up from 2M to 4M, 2M is too small on Solaris

Rework libldap to not attempt to set LDAP_API_FEATURE_X_OPENLDAP_THREAD_SAFE

Decrease default thread stack size from 16MB to 2MB

Added thread-pool getkey/setkey functions

Update copyright notices

Delete ldap_build_filter(), it's broke.
Clean up headers.

Low stack to 16 MB... this really needs to be tunable

Use a 64MB stack (instead of a 64K on some systems) by default.
This should be tunable...

Update copyright (including with or without modification clarification)

Added "threads" config to slapd.conf.

Round one of LDAP_F() macro changes.  In this round we rename
macros into our namespace and limit use to headers.  A subsequent
round will add macros to separately handle forward declarations
of variables from declaration of function prototypes.  The last
round will add additional macros for declaring actual variables and
functions.

Reworked thread code to better support thread-library specific
r/w locks and thread pools.  Hide internal structures (using
pthread'ish technics).  Place common code in threads.c.  Move
no-thread code to thr_stub.c.  Move thread pool code to tpool.c.
Removed setconcurrency call from initializer, added 'concurrency'
directive to slapd.  Tested code under pthreads, pth, and no-threads.

Add thread pool routines.

Use pthread rwlocks, if available

In preparation for thread pools

before including <pth.h>:
#define PTH_SYSCALL_SOFT 1

Y2k copyright update

Fixes for NT dynamic linking.

Additional mods to fix NT single threaded support.

Use centralized output directories.
Update single debug/release not to use service manager nor event manager.
Likely breaks MINGW32 port.

Fix broken MSVC builds. The previous round of Mingw32 patches changed some
ifdefs to depend on _WINNT, which is bogus. Added _WIN32 back on these ifs,
and fixed some other include problems.

Fixed the LDAP_F macro.
See README 1.27 log

Add OpenLDAP RCS Id

Support for native GNU Pth Threads (--with-threads=pth)
Tests behave as expected excepting slapd sometimes does not
shutdown properly.

Remove HAVE_THREADS define.  NO_THREADS is used instead.

Vienna Bulk Commit
This commit includes many changes.  All changes compile under NT but
have not been tested under UNIX.

A Summary of changes (likely incomplete):

NT changes:
	Removed lint.
	Clean up configuration support for "Debug", "Release", "SDebug",
		and "SRelease" configurations.
	Share output directories for clients, libraries,
		and slapd.  (maybe they should be combined further
		and moved to build/{,S}{Debug,Release}).
	Enable threading when _MT is defined.
	Enable debuging when _DEBUG is defined.
	Disable setting of NDEBUG under Release/SRelease.  Asserts
		are disabled in <ac/assert.h> when LDAP_DEBUG is not
		defined.
	Added 'build/main.dsp' Master project.
	Removed non-slapd projects from slapd.dsp (see main.dsp).
	Removed replaced many uses of _WIN32 macro with feature based
		macros.

ldap_cdefs.h changes
	#define LDAP_CONST const
		(see below)
	#define LDAP_F(type) LDAP_F_PRE type LDAP_F_POST
		To allow specifiers to be added before and after
		the type declaration.  (For DLL handling)

LBER/LDAP changes
	Namespace changes:
		s/lber_/ber_/ for here and there.
		s/NAME_ERROR/LDAP_NAME_ERROR/g
	Deleted NULLMSG and other NULL* macros for namespace reasons.
	"const" libraries.  Installed headers (ie: lber.h, ldap.h)
		use LDAP_CONST macro.  Normally set to 'const' when
		__STDC__.  Can be set externally to enable/disable
		'constification' of external interface.  Internal
		interface always uses 'const'.  Did not fix warnings
		in -lldif (in lieu of new LDIF parser).

	Added _ext API implementations (excepting search and bind).
		Need to implement ldap_int_get_controls() for reponses
		with controls.

	Added numberous assert() checks.

LDAP_R
	_MT defines HAVE_NT_THREADS
	Added numberous assert() checks.
	Changed ldap_pthread_t back to unsigned long.  Used cast
	to HANDLE in _join().

LDBM
	Replaced _WIN32 with HAVE_SYSLOG

ud
	Added version string if MKVERSION is not defined.  (MKVERSION
		needs to be set under UNIX).

slapd
	Made connection sockbuf field a pointer to a sockbuf.  This
		removed slap.h dependency on lber-int.h.  lber-int.h now only
		included by those files needing to mess with the sockbuf.
	Used ber_* functions/macros to access sockbuf internals whenever
		possible.
	Added version string if MKVERSION is not defined.  (MKVERSION
		needs to be set under UNIX).
	Removed FD_SET unsigned lint

slapd/tools
	Used EXEEXT to added ".exe" to routines.  Need to define EXEEXT
		under UNIX.

ldappasswd
	Added ldappasswd.dsp.  Ported to NT.  Used getpid() to seed rand().

nt_debug
	Minor cleanup.  Added "portable.h" include and used <ac/*.h> where
	appropriate.  Added const to char* format argument.

Clean up valid flag: _VALUE -> _VALID.

fix typo on destroy

Add ldap_pvt_thread_destory() to un-ldap_pvt_thread_initialize().
Move all SunOS routines (ie: _sleep() and its helpers) to thr_lwp.c
so that it's internals can be 'static'.  Add 'static' to thr_lwp.c.
Add comment to LWP:  NEEDS WORK, may not compile!  Need some
SunOS user to sort out the details.  Volunteers?

Fix dbcache/entry lock deadlock.  If dbcache lock is held, it's
okay to read and write LDBM specific fields (state, refcnt,
LRU.  The id field, though is read-only once set.
cache_find_entry_dn2id(), hence, does not require any entry locks.
cache_find_entry_id() must do a entry_rdwr_trylock() and back
off if busy.
Add new rdwr lock code with trylock() functionality.
Implement entry_rdwr_trylock().

Fix set concurrency typos.

Add cond/rdwr destroy routines.

Use -lldap_r instead of -lldap -lthread.
	Likely broke things for non-posix threadings....

Update -lldap_r implementation to:
	remove attribute support
	hide thread detachment
	provide concurrency accessors
	provide initialization function
	fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread

Fixup begin/end declaration tags
Assume portable.h has been included
Include ldap_cdefs.h at the top.

Fix minor typo in lthread.h (which was copied into ldap_pvt_thread.h).

Updates for the new threading and utility stuff in libldap{_r}.
