From 63f1ba7ab140cada16c54ad9913a3f95ff565410 Mon Sep 17 00:00:00 2001 From: Jeffrey Stedfast Date: Mon, 19 Feb 2001 23:38:53 +0000 Subject: New handy dandy function to ref and return the vfolder storage (will 2001-02-19 Jeffrey Stedfast * mail-vfolder.c (mail_vfolder_get_vfolder_storage): New handy dandy function to ref and return the vfolder storage (will probably be disavowed once I figure out how to get the vTrash folder to show up in the EvolutionLocalStorage). * main.c (main): Call vtrash_cleanup(). * mail-vtrash.c: New file. (vtrash_uri_to_folder): vtrash: URI handler (vtrash_create): Replacement async vtrash function for the old one in mail-ops.c (vtrash_cleanup): Cleanup code - unrefs the cached vtrash folders and free's the hashtable. * Makefile.am: Added mail-vtrash.[c,h]. * mail-tools.c (mail_tool_uri_to_folder): If we have a vtrash: URI, call the vtrash URI handler function rather than continuing on. Yes, I know this is a hack and it needs to be fixed. * mail-ops.c (mail_do_setup_trash): Removed. (mail_trash_get): Removed. * component-factory.c (owner_set_cb): Create the vTrash folder for the LocalStore here. * mail-local.c (get_folder_info): Implement. svn path=/trunk/; revision=8288 --- mail/mail-vtrash.c | 291 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 291 insertions(+) create mode 100644 mail/mail-vtrash.c (limited to 'mail/mail-vtrash.c') diff --git a/mail/mail-vtrash.c b/mail/mail-vtrash.c new file mode 100644 index 0000000000..c8e91ea669 --- /dev/null +++ b/mail/mail-vtrash.c @@ -0,0 +1,291 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: t; c-basic-offset: 8 -*- */ +/* + * Authors: Jeffrey Stedfast + * + * Copyright 2001 Ximian, Inc.
