2000-11-21  Not Zed  <NotZed@HelixCode.com>

	* providers/local/camel-mh-summary.c (mh_summary_sync_message):
	Shite, -1 on error, >=0 on success.  So i've just been truncating
	all the messages I touched, good one zed.
	(mh_summary_sync_message): Sigh, and write to the right damn fd as
	well.
	(mh_summary_sync_message): Argh, and we need to compare the length
	of the old xev -1 to the new xev, to check if we can optimise it.

	* camel-folder.c (camel_folder_change_info_new): Init the pool.
	(camel_folder_change_info_add_source): Allocate string in the
	pool.
	(camel_folder_change_info_add_source_list):
	(camel_folder_change_info_add_update): No longer free the key, as
	it cannot be yet.
	(change_info_add_uid): Add a new arg, copy, telling it whether to
	copy the uid argument or not, and copy using mempool_strdup.
	(change_info_cat): Tell add_uid to copy the string.
	(camel_folder_change_info_add_update): Call add_uid directly.
	(change_info_remove): Call add_uid directly, with no copy, and
	dont free the key.
	(change_info_free_update): No longer required since we dont malloc
	the keys.
	(camel_folder_change_info_add_uid): Fix for add_uid change.
	(camel_folder_change_info_remove_uid):
	(camel_folder_change_info_change_uid):
	(change_info_clear): No longer needed, just set the size to 0 on
	the array directly.
	(camel_folder_change_info_clear): Empty the arrays directly, and
	flush the mempool too, and also clear uid_source, incase anyone
	was silly enough to call us in the wrong order.
	(camel_folder_change_info_free): Dont bother clearing the array's
	contents, just free the pool and throw away all the indexes.

	* camel-folder.h: Added a mempool to CamelFolderChangeInfo to
	store the uid's we get.

	* camel-folder-search.c (search_match_all): If we are only
	matching a single info, just use that/do the search.
	(camel_folder_search_match_expression): New function.  Matches a
	single message info against an expression.
	(camel_folder_search_init): Init a hash table used to map the
	returned gptrarrays' to mempools.
	(camel_folder_search_execute_expression): Store all of the string
	data in a mempool, slightly faster, less wasted space (usually),.
	(camel_folder_search_free_result): Check for the mempool that
	stores the data for the list, and free that if we have it,
	otherwise assume we need to use g_free() (which should only happen
	if the list is empty at the moment).
	: commented out the debugging prints.  Got sick of 'executing
	header search' crap.

	* providers/vee/camel-vee-folder.c (camel_vee_folder_init): Init
	changes.
	(camel_vee_folder_finalise): Free changes.
	(vfolder_add_match): Simple helper to add a new matching info
	record.
	(camel_vee_folder_add_folder): Only trigger a changed event if we
	have changes.
	(vfolder_change_match): New function, changes our local vfolder
	info to match the source.
	(vfolder_add_match): Add a new info to the vfolder list.
	(vfolder_remove_match): Remove a no-longer matching info from the
	vfolder summary.
	(message_changed): check if the message still matches, and
	remove/etc as required.
	(camel_vee_folder_finalise, init): init/free search object.
	(vee_folder_build_folder): Build the changes to the folder into
	the changes data, as we go.
	(folder_changed): If the folder gave us an explicit list of
	changes, then process each one separately (unless there's a lot
	added/changed).

	* providers/vee/camel-vee-folder.h: Added a changes field to the
	folder.
