library, not header. Eliminate need for <ac/unistd.h> to sometimes
include <fcntl.h> and/or <sys/file.h>. Change lock API to expect
fd not FILE*. Allows wider use and eliminates requirement that
lutil_lockf.h depencency on stdio.h.
Implemented lockf, fcntl, and flock locking in lutil/lockf.c.
Additional implementations (including no-op) may be needed.
Update slapd/lock.c and slurpd/lock.c to use new API.
by portable.h with NDEBUG undefined. This makes assert() is always
available and automatically disables itself when LDAP_DEBUG is undefined.
I've included a basic assert() for pre-STDC compilers. It relies on
abort() which may not actually be available. (well replace abort()
with whatever is appropriate if and when we're faced with a pre-STDC
compiler that doesn't have assert()).
lber: ifdef'ed out lber_..set_nonblock() function because it used ioctl's.
If it remains, it needs to be written to support various methods for
setting non-blocking. ioctls should probably be last choice. configure
could detect existance of fcntl(), ioctl(), etc.
bdb2:
added .dsp/.dsw files and did some basic cleanup (still needs work).
which only part of a LDAPMessage is available on a socket.
The server-code seemed to handle this correctly already, so I didn't touch
it.
My apologies for the hack in ber_get_next :-).
Implementation no longer uses strtok_r(), it may be broken
or have an odd prototype.
Update configure not to check for strtok/strtok_r nor require
strtok_r to LDAP_API_FEATURE_X_OPENLDAP_REENTRANT.
Integration into ./configure ( --enable-bdb2 ).
Adaptation of the test-suite ( 'make' -> ldbm; 'make bdb2-local' -> bdb2 ).
Minor fixes in slapd/libldbm.
Separates per backend type from per backend database initialization
and startup. Also supports per type / per backend shutdown.
New frontend startup/shutdown routines are also provided:
slap_init() slap_startup() slap_shutdown() slap_destroy()
New frontend->backend startup/shutdown is managed by:
backend_init() backend_startup() backend_shutdown backend_destroy
backend_init() now calls bi_init() to initial all function pointers
for the backend (excepting bi_init() which is now the only hardcoded
entry point). New entry points are detailed in slap.h struct
backend_info. backend_info is a per database type structure.
Besides the new startup/shutdown entry points, the new interface
also supports per backend type configuration options. One could have:
backend bdb2 (new Berkeley DB 2 backend)
bdb2_home /directory
database bdb2
...
*** This code is fairly experimental ***
*** Much cleanup and testing is still needed ***
see slap.h for details on struct backend_db and backend_info.
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().
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
back-ldbm was using a cache specific lock to protect non-reentrant
database routines from being reenterred. This is inadequate.
Also, reentrant database systems calls were serialized unnecessarily.
Non-reentrant database calls must have a big_mutex. Implemented
this within -lldbm itself. library requires ldbm_initialize()
be called before any other ldbm call to initialize the big_mutex
and to do any other db specific initialization (ie: such as
required for DB2).
The dbc_mutex, dbc_cv, & dbc_readers fileds of dbcache are history.
The "reentrant_database" (REENTRANT_DATABASE) define is also axed.
Redefine Debug macro to call ldap_log_printf(NULL, lvl, fmt, ...)
Should replace each Debug statement with direct call to ldap_log_printf
passing LDAP session if available.
libldap/string.c will hold various string.h replacements.
Removed liblutil/strdup.c
Moved ldap_pvt_strtok to string.c.
Moved prototype of ldap_pvt_strtok to <ac/string.h>.
Added #define strtok_r ldap_pvt_strtok (if strtok_r doesn't exist).
BerElement argument per latest IETF ldapext draft c api spec.
That is, caller is solely responsible for freeing the BerElement
allocated and returned by ldap_first_attribute.
Update man pages accordingly.
Update applications accordingly.
simulated with strspn and strpbrk. If strspn or strpbrk aren't there, they
will be supplied.
In addition, the memory-handling of the ldap_int_gethostby's is better now.
end of link. Basic order is:
$LDFLAGS internal-libs external-libs $LIBS $LTHREAD_LIBS
LTHREAD_LIBS is last as -lpthread (or equiv) must be last on many systems.
LIBS is next to last as some user might have put -lpthread (or equiv)
in $LIBS.
of a busy wait and allow the pthread_yield within the loop to be
removed. This was the only pthread_yield which was necessary
when usng non-preemptive threads. As such, the configure.in
sched_yield/pthread_yield missing error can be removed from
configure.in. If explicit yield function is missing, just provide
a no-op replacement.
Moved declaration of various slapd globals from main.c to init.c
so they can be shared with ldbm tools.
