From 33dc07649030535d44ed5a1b733917acd70405da Mon Sep 17 00:00:00 2001 From: Christopher James Lahey Date: Mon, 11 Jun 2001 06:47:07 +0000 Subject: Made it so that all of these functions queue their ops before calling 2001-06-11 Christopher James Lahey * backend/ebook/e-book.c (e_book_load_uri, e_book_get_supported_fields, e_book_authenticate_user, e_book_remove_card_by_id, e_book_add_vcard, e_book_commit_vcard, e_book_get_cursor, e_book_get_book_view, e_book_get_changes): Made it so that all of these functions queue their ops before calling their CORBA functions. This way, if the response is sent back before the CORBA function returns there's no problem. Added e_book_unqueue_op so that the op could be unqueued if the CORBA call fails. svn path=/trunk/; revision=10180 --- addressbook/ChangeLog | 10 ++++++ addressbook/backend/ebook/e-book.c | 74 +++++++++++++++++++++++++++++--------- 2 files changed, 68 insertions(+), 16 deletions(-) diff --git a/addressbook/ChangeLog b/addressbook/ChangeLog index dbb085268e..3b04b46f32 100644 --- a/addressbook/ChangeLog +++ b/addressbook/ChangeLog @@ -1,5 +1,15 @@ 2001-06-11 Christopher James Lahey + * backend/ebook/e-book.c (e_book_load_uri, + e_book_get_supported_fields, e_book_authenticate_user, + e_book_remove_card_by_id, e_book_add_vcard, e_book_commit_vcard, + e_book_get_cursor, e_book_get_book_view, e_book_get_changes): Made + it so that all of these functions queue their ops before calling + their CORBA functions.
