Added a 'first' member to the imap_fetch_all_t struct so we can use that
2004-06-16 Jeffrey Stedfast <fejj@ximian.com> * providers/imap4/camel-imap4-summary.c: Added a 'first' member to the imap_fetch_all_t struct so we can use that as a base offset in our GPtrArray, allowing us to limit resource consumption which could otherwise get quite large. Also added a ChangeInfo member that was needed for changes to untagged_fetch_all(). (imap4_fetch_all_add): Use fetch->first as a base offset and change int i to guint32 i. Also updated to sue the fetch->changes. (imap4_fetch_all_update): Same. (untagged_fetch_all): Same - this is where it is really valuable, since we can avoid adding elements to the GPtrArray that we won't even use. Also needed to change code a big in case index < fetch->first (which could happen if a server notified us of a FLAGS change for a message we didn't request info about). (imap4_fetch_all_free): Free the ChangeInfo. (imap4_summary_fetch_all): Init fetch->changes and fetch->first. (imap4_summary_fetch_flags): Same. svn path=/trunk/; revision=26370
