* ibex_internal.h (IBEX_TRYLOCK): Added a trylock, used by ibex_use.
* ibex_block.c (ibex_use): Do to a trylock on the ibex we're
checking to close, as it might be locked elsewhere in an obivously
simple deadlock.

* ibex_internal.h (IBEX_OPEN_THRESHOLD): Bump this to 15, 5 seems
a little small. Its still settable using an environmental
variable though, hopefully with other fd optimisations this will
not be an excessive number.

* ibex_block.c (ibex_reset): If we can't open blocks, dont try to
deref it.
(ibex_move): Dont try to rename if we have no file to rename.
Change all callers to ibex_use to call it inside the lock.
Otherwise it could change while we're trying to use it ...
(ibex_use): Dont lock ib here, always assume we have it locked
already, and dont try to close it if we run across it in the list.

* ibex_block.c (ibex_use): New function to limit use of fd's.
Mark an ibex file in use, re-open if necessary, and close off
another (lru) if necessary.
(ibex_unuse): Mark an ibex as not in use.
(ibex_open): Delay opening of the actual block file till later,
and add the ibex to a global list.
(ibex_save): Use/unuse around operations.
(close_backend): Zero out blocks when closed.
(ibex_close): Remove the ibex from the global list before closing
it down.
(ibex_index_buffer, ibex_find, ibex_unindex, ibex_find_name):
Use/unuse around ops.

* wordindexmem.c (sync_cache_entry): NOOP if writing to a failed
file.

keep track of it.
(ibex_block_cache_sync): Dont do anything if we've failed on this
file.

where dealing with external data.

macros, and include a setjmp buffer for returning it.

wordindexmem is what's used.

faster when starting indexing of new data.
2000-10-26 Not Zed <NotZed@HelixCode.com>
* block.c (ibex_block_cache_open): Use IBEX_VERSION rather than
hardcoded version string.
* ibex_internal.h (IBEX_VERSION): Bumped version again. This time
I did change the index format.
* hash.c (struct _hashroot): Add a linked list of keys to the table.
(struct _hashblock): Added a next pointer as a block number.
(hash_insert): Link new key blocks into the key block list.
(struct _HASHCursor): Renamed block to key and added a block item.
(hash_cursor_next): Changed to go through the linked list of all
hash items rather than through each hash chain separately. >>
faster.
(ibex_hash_dump_rec): Remove a warning.

before, and be more bugfree than ever!
2000-10-25 Not Zed <NotZed@HelixCode.com>
* ibex_internal.h (IBEX_VERSION): Bumped to another version. The
file format hasn't changed, but earlier bugs may create invalid
files.
* block.c (ibex_block_read): Use the root data directly.
(ibex_block_cache_open): As well.
(ibex_block_get): And here too.
(ibex_block_cache_sync): Sync the root block directly here.
* block.h: Pad root block out to 1024 bytes.
Added root block to struct _memcache.
* disktail.c (tail_get): Dirty the root block.
(tail_get): Fix for changes to root access.
(disk_remove): And here too.
* wordindexmem.c (sync_cache_entry): Handle the case of not having
any files in the list, which can happen now.
(word_index_pre): Make sure we set the wordid on the new cache
entry.
* ibex_block.c (ibex_save): Sigh. Pass the right argument to
index_post.
* block.c (ibex_block_cache_open): Create a word_index_mem for
indexing the words, rather than a word_index.
* ibex_block.c (ibex_index_buffer): If we haven't called index_pre
yet, do it before indexing anything.
(ibex_save): If wehave called index_pre previously, call
index_post.
(ibex_close): And same for here.
* index.h: Added a cursor class, and cursor retrieval function for
iterating through an index's keys.
* wordindexmem.c (ibex_create_word_index_mem): New word class,
similar to wordindex, but meant to be faster for updates.
(word_index_pre): Implement. We load all keys into memory.
(word_index_post): Implement. We sync and free all keys.
(find): Remove lru code, its no longer a cache, but a lookup
table.
(add_index_cache): Remove lru code here too.
(find_name): And here.
(word_flush): Flush the hashtable direct.
(word_close): Call flush to flush, rather than doing it ourselves.
(add_index_cache): If we are in an index state, we can assume a
cache miss == a new word.
(word_index_post): Maintain whether or not we are in an index
state, and the depth of the state.
(word_index_pre): Likewise. Dont reread the index if we have
already.
(cache_sanity): Fixed for struct changes.
* wordindex.h (IBEXWordClass): Added functions to prepare/cleanup
for lots of indexing. i.e. can be used to optimise indexing speed
at the cost of extra memory usage during the indexing process.
* hash.c (hash_cursor_create): Create a new cursor for iterating through a
hashtable.
(hash_cursor_close): 'close' the cursor. It is upto the
application to close any cursors it creates.
(hash_cursor_next): Goto the next key id.
(hash_cursor_next_key): Goto the next key, reutrn the key.
(hash_get_cursor): Return a cursor object.
* wordindex.c (word_index_post):
(word_index_pre): Added (empty) callbacks for pre/post functions.

because of the hash table size change.
