BDB's default key sort algorithm sorts in the wrong order (and there's no
convenient way to select the correct algorithm). This is an incompatible
change to the database format but will improve back-ldbm's add/delete
characteristics.
Now operations that set the status of an entry to CREATING (add.c, modrdn.c)
need to set it to COMMIT, by calling cache_entry_commit, before returning
the entry itself, otherwise the entry is removed from the cache
and its private data is freed.
Should fix crashes due to add failures as in ITS#1245
Old code applied sync flags to store(), however supported DBMs
require such flags to be specified during open(). The new
code now applies flags in ldbm_cache_open (which calls ldbm_open).
ldbm_cache_close() now calls ldbm_sync(). This will force
a updating of on-disk contents after each LDAP operation.
The old code either failed to sync the on-disk contents until
close or synced on every store. Per LDBM operation syncing
*should* be safe enough... real data safety requires transactions.
Removed nosync option from BDB2 as it is not compatible with
txn support.
Also added code to disable DBM level locking as slapd is only
process acessing the databases (dbnolocking).
added slap_ and ldbm_ to many structures
added typedefs to many structures
used typedefs
New main.c argument parsing with ldap url support (replacing -a address).
New sockaddr_in handling and support for multiple listeners.
id2entry: when an error occurs attempting to insert fetched
entry into cache, check to see if entry was added by another
thread. If so, return the entry added by the other thread.
The concurrency tests now run without the dreaded "no such object"
error messages!
cache_set_state() and state args are no history.
Move cache_entry_cmp() and friends to slapd/entry.c to allow sharing
of functions between backends.. Renamed to entry_cmp().
The new e_private field can be used for any backend purpose. In LDBM,
it's used to point th the private entry info struct. The LDBM entry
info struct is only visible to the LDBM cache.
WARNING: This change has not be ported to other backends! Breakage is likely.
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
Most function and variable definitions are now preceded by its extern
definition, for error checking. Retyped a number of functions, usually
to return void. Fixed a number of printf format errors.
API changes (in ldap/include):
Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.
A number of `extern' declarations are left (some added by protoize), to
be cleaned away later. Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.
