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.
make depend, make tests, and make install all work when build directory
is not the $srcdir.
Also modified library handling such that -lpthread more likely to be last.
WARNING: new orderring requires use of LDFLAGS to set global loader options
such as -L/usr/local/lib. If you put this in LIBS, some libraries
may not be found a link time.
Likely broke Kerberos/LDAPD support. Don't have those in my testbed.
- slapd's pid/args file names are based on the servers binary file names,
providing for multiple servers beeing run on one host.
- slapd supports the -l command line parameter for selection of a
syslog LOCAL user (-lLOCAL0 .. -lLOCAL7)
- db_appinit() is called during first ldbm_open() in DB 2.x to initialize
DB debugging features (good to find bugs in the DB code :-)
- a patch for a non-initialized variable in DB's 2.x db_open is provided.
one preprocessor macro instead of two. Ran aclocal, autoconf,
autoheader to update derived files. Modify util-int.c to use
CTIME_R_NARGS define and fallback to ctime() if not set.
Made LDAP_API_FEATURE_X_OPENLDAP_REENTRANT dependent upon result.
