| | | | | | | | | | | | 2001-10-31 <NotZed@Ximian.com> * 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. svn path=/trunk/; revision=14547

| | | | | | | | | | | 2001-10-30 <NotZed@Ximian.com> * 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. svn path=/trunk/; revision=14471

| | | | | | | | | | | | | | 2001-10-30 <NotZed@Ximian.com> * 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. svn path=/trunk/; revision=14430

| | | | | | | | | | | | | | | | | | | 2001-08-15 Not Zed <NotZed@Ximian.com> * 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. svn path=/trunk/; revision=12042

(word_index_pre): NOOP if failed file. (ibex_create_word_index_mem): Setup blocks value. ** Added internal exception handling to libibex, in the case of errors with on-disk data, exceptions are returned. * block.c (ibex_block_cache_open): Detect fatal errors below us and clean up appropriately. (ibex_block_cache_fail): New function to handle the failure, and keep track of it. (ibex_block_cache_sync): Dont do anything if we've failed on this file. * disktail.c (tail_compress): Add blocks param so we can assert for exceptions. * hash.c, block.c disktail.c: g_assert->ibex_block_cache_assert where dealing with external data. * hash.c (hash_info): Add index param so we can assert for exceptions. * ibex_block.c (ibex_index_buffer): Setjmp before calling into internal routines. (ibex_save): " (ibex_unindex): " (ibex_find): " (ibex_find_name): " (ibex_contains_name): " (ibex_reset): Function to reset the index file if we have an error, call when we have an error. * block.h (ibex_block_cache_assert): Create assertion/exception macros, and include a setjmp buffer for returning it. 2001-08-09 Not Zed <NotZed@Ximian.com> * Makefile.am (libibex_la_SOURCES): Remove wordindex.c, wordindexmem is what's used. svn path=/trunk/; revision=11864

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.

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. svn path=/trunk/; revision=6165
