+ (text_index_sync): Drop the cache limits back down again, we dont
+ need them when looking words up.
+
+ ** MERGE camel_index branch.
+
+ * camel-text-index.[ch]: Added files i forgot to add (eep nearly

+
+ * camel-block-file.c (sync_nolock): Fix an infinite loop in syncing.
+
2002-03-21 Jeffrey Stedfast <fejj@ximian.com>
* camel-folder-summary.c (camel_message_info_new_from_header): Use
the date in the received header for the received_date.
+2002-03-22 Not Zed <NotZed@Ximian.com>
+
+ * providers/local/camel-local-folder.c
+ (camel_local_folder_construct): Use the right option to remove the
+ index file and reset the index file on creation.
+ (camel_local_folder_construct): Remove any existing '.ibex' files
+ - these are the old format index files.
+
+ * camel-block-file.c (camel_block_file_rename): Lock io lock while
+ renaming.
+ (camel_key_file_rename): Lock around rename.
+ (block_file_validate_root): Implement sync flag checking.
+ (camel_block_file_touch_block): Turn off the sync flag if we're
+ touching any non-root block and write it to disk. Shoudl this
+ fsync()?
+ (sync_nolock): sync the root block only if we need to.
+
+ * providers/local/camel-local-store.c (rename_folder): Re-enable
+ index rename code. Not sure how race-free it is though.
+ (delete_folder): Delete the index file properly.
+
+ * camel-partition-table.c (camel_key_table_lookup): Initialise
+ output values to 0 before doing anything.
+ (camel_key_table_add): Do some range-checking on values.
+
+ * camel-text-index.c (text_index_compress): Changed to call sync here.
+ (text_index_compress_nolock): and not here - stops a recursive
+ sync call when sync performs a compress also.
+ (text_index_compress_nolock): Change to _nosync, since the locking
+ is irrelevent (recursive lock). Fixed callers.
+ (text_index_add_name_to_word): If we get a failure with key table
+ ops, fail immediately.
+ (text_index_compress_nosync): Likewise.
+ (text_index_write_name): If the nameid is 0, do nothing.
+ (text_index_add_name): If we can't get a keyid, dont add it to the
+ partition table.
+ (camel_text_index_remove): Function to delete an index file.
+ (text_index_compress_nosync): Clean up temp files when done.
+
+ * camel-folder-search.c (match_messages_index): New function,
+ split from body_contains, matches a regex against all words in an
+ index.
+ (match_message_index): Similar to above but matches against an
+ individual message.
+ (search_body_contains): Changed to use above functions for
+ matching - substring matches should now work on indexed data.
+
+2002-03-21 Not Zed <NotZed@Ximian.com>
+
+ * camel-index.c (camel_index_words/names): New virtual
+ methods/stubs to get a cursor of all words and names.
+
+ * camel-text-index.c (text_index_compress_nolock): Split from
+ text_index_compress, so we can call the compressor while locked
+ also, removed lock calls.
+ (text_index_compress): Changed to stub which calls
+ text_index_compress_nolock.
+ (camel_text_index_key_cursor_new): New object to iterate through
+ a key table.
+ (text_index_words, text_index_names): Implement virtual functions
+ for iterating through all words or names.
+
+ * camel-block-file.c: Turn off some debug.
+
+2002-03-20 Not Zed <NotZed@Ximian.com>
+
+ ** New body index implementation.
+
+ * camel-index*: Code for camel index, a new class to replace ibex.
+
+ * camel-block-file.[ch]: block-based and link based
+ filesystem-in-a-file classes.
+
+ * camel-partition-table.[ch]: An implementation of a partition
+ table (automatically extending on-disk hash-table using ideal
+ hash), and a key-table, a key<>name mapping table. Used by
+ camelindex.
+
+ * providers/local/*, camel-folder-summary.[ch]: Changed to use
+ camel-index interface rather than ibex.
+
+2002-03-05 Not Zed <NotZed@Ximian.com>
+
+ * providers/local/camel-maildir-summary.c (maildir_summary_check):
+ Do progress reporting of operations.
+ (maildir_summary_sync): Same here.
+
+2002-03-04 Not Zed <NotZed@Ximian.com>
+
+ * providers/local/camel-spoold-store.c (scan_dir): Kill a warning
+ with a cast.
+
+ * providers/local/camel-*.c: Changed for ibex->camelindex.
+
+ * camel-folder-search.c (camel_folder_search_set_summary): Init
+ summary_hash to point to 'static' uid strings.
+ (search_body_contains): Use the static uid memory to return
+ results rather than the values from the index library.
+
+ * camel-folder-search.[ch]: Changed to use camelindex object.
+
+ * camel-folder-summary.c (summary_build_content_info_message):
+ Use a stream to index content, also filter html mail first.
+ (camel_folder_summary_info_new_from_message): Use a stream
+ filtered to index content.
+ (main): Removed the test main code. Added headers for open call
+ (ibex must've had them before).
+
+ * camel-folder-summary.[ch]: Changed from ibex to CamelIndex.
+
+ * camel-mime-filter-index.c (camel_mime_filter_index_finalize):
+ Unref index.
+
+ * camel-mime-filter-index.[ch]: Changed from ibex to CamelIndex.
+
2002-03-19 Jeffrey Stedfast <fejj@ximian.com>
