420210a2a3 IDL cache locking change (mutex -> rwlock) 2003-04-08 06:57:07 +00:00

e8c58b4e7f Major API change - (SLAP_OP_BLOCKS) All request parameters are 
consolidated into the Operation structure. All reply parameters
are consolidated into the new SlapReply structure. Most operations
now have identical call signatures... Changes are not #ifdef'd,
revert to -r NO_SLAP_OP_BLOCKS if necessary to back out.

0be6cb5a67 Deleted bi_database_mutex, use DB_LOCK instead. Changed bdb_locker_id to 
lookup the threadctx if no Op * is provided. (bdb_db_cache doesn't know
its thread context when it acquires a locker ID.)

18554e7511 Fix attribute/group to allow TXN to abort on lock failure. Save and 
restore op->o_do_not_cache on TXN retry, bdb_group will set it if it
fails to get a lock.

349e05ff4d Added config keyword "searchstack" for setting search stack cache depth. 
Default is still 16.

Added IDL caching, modified from ITS#2182. Uses "idlcachesize" config
keyword. Code is #ifdef'd, currently defined, with default cache of 0.

919274432b Fixes for NO_THREADS 
Use a per-env locker ID
	Always set lock_detect, since we allow slapadd etc. concurrently
Also removed unused lock_detect_task code. lockdetect config keyword only
needs <policy>, no <seconds> argument.

d6449b1d57 Experimental code that uses one locker ID per thread. Seems to work OK, 
is enabled by default. #undef BDB_REUSE_LOCKERS in back-bdb.h to disable.
Probably needs to be disabled when built with NO_THREADS.

1d9818a8da Re-introduce BDB_ID2ENTRY_PAGESIZE. Even if the index databases can get 
by on 4K pages, the id2entry database still needs more (16K).

a19a5d8c15 When using BDB_IDL_MULTI, there are no longer any issues with storing 
large IDLs. Concurrency is improved by using as small a page size as
possible. So, set the pagesize back to the default 4096 in this case.

859e283834 Experimental index management. Uncomment BDB_IDL_MULTI in back-bdb.h 
to activate. Needs to check limits in bdb_idl_insert_key, will get to
that later.

295e14bd54 Renamed BDB_ID2ENTRY_PAGESIZE to just BDB_PAGESIZE; set it on each database 
instead of just the id2entry db. It helps. I also found that tweaking the
environment (set_lg_bsize 2MB; set_cachesize 2MB) helps but those can be
taken care of in a DB_CONFIG file. Tweaked the bdb_bt_compare function; it
really only needs to be set on little-endian machines. (On big-endian machines
a lexical sort gives the same result as an integer sort.) Moved the final
checkpoint back to the dbenv_close, I think this leaves a cleaner log file.

5c7a7998a9 Set the id2entry database pagesize to BDB_ID2ENTRY_PAGESIZE to avoid 
overflow/fragmentation. (This is now 16K vs default 4K.) It turns out
that the entries' on-disk format is quite space-inefficient, storing
4 bytes per pointer or integer when typically >50% of those bytes are
zero. Oh well. It's about a 2:1 space increase over ldbm now, vs 4:1
before when all the entries were overflowing the 4K pages.

b45133c958 Eliminated nextid database. id2entry database is now maintained in numerical 
order, so the lastid is always the same as the last entry's ID. This is
an incompatible db file change.

323689da57 Added "dbnotxn" config keyword. If present, back-bdb uses DB_INIT_CDB 
(Concurrent Data Store mode) instead of DB_INIT_TXN. Faster, but tends
to impede writers.
