[fejj svn gnome org]

Author: fejj
Date: Mon May 12 14:04:02 2008
New Revision: 8783
URL: http://svn.gnome.org/viewvc/evolution-data-server?rev=8783&view=rev

Log:
2008-05-12  Jeffrey Stedfast  <fejj novell com>

	* camel-imap4-summary.c (camel_imap4_summary_flush_updates):
	Properly handle empty folders.

	* camel-imap4-store.c (connect_to_server): Disconnect the engine
	if SSL negotiations fail (there's no other way for the engine to
	know that failed).

	* camel-imap4-engine.c (camel_imap4_engine_disconnect): New
	convenience function.

2008-05-11  Jeffrey Stedfast  <fejj novell com>

	* camel-imap4-utils.c (camel_imap4_build_folder_info_tree): New
	utility function.

	* camel-imap4-store-summary.c (camel_imap4_store_summary_get_folder_info):
	Use a custom imap4 routine to create a folderinfo tree.

	* camel-imap4-summary.c (imap4_fetch_all_add): Need to ref the
	CamelMessageInfo after adding to the summary because
	camel_folder_summary_add() does not ref.

	* camel-imap4-store.c: Define some symbols that might not exist in
	the version of camel we are linking against.
	(imap4_build_folder_info_tree): New function to build a tree
	structure of CamelFolderInfo's from an array.
