7c8c5213b1 BDB_MULTI still needs the dupsort function. 2001-12-18 04:41:40 +00:00

4ddb7c5730 Use a 4-byte constant for the presence index key. Set the index db hash 
function to simply pass thru the key value, which is already a hash value.

bf61a1ca9d Use DB_HASH instead of DB_BTREE for index databases. Since index keys are 
mainly 4-byte hashes already, there is no locality-of-reference to exploit
as a Btree. About a 7% performance gain.

4ed4b3f0c0 Revert previous checkin, DB_NODUPDATA is not valid on db->set_flags(). 
It must be specified on individual put() operations (and already is).

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

that later.

180e1d5269 Don't maintain a DN_SUBTREE index for the backend suffix, just return 
BDB_IDL_ALL. This has a huge impact on I/O and txn logs.

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.

SLAP_MR_ASSERTION_SYNTAX_MATCH
	SLAP_MR_VALUE_SYNTAX_MATCH
	SLAP_MR_VALUE_SYNTAX_CONVERTED_MATCH,
add supporting evaluation macros, and update code as needed.
Misc other code cleanup included.

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.
