From 4c20fe02c4bf78e56caf5393598fdb71b4ac772e Mon Sep 17 00:00:00 2001 From: Jeffrey Stedfast Date: Tue, 4 Jun 2002 23:58:22 +0000 Subject: The following changes take a great leap toward fixing bug #1042. 2002-06-04 Jeffrey Stedfast The following changes take a great leap toward fixing bug #1042. * mail-display.c (mail_display_push_content_location): New function to push a Content-Location value onto the MailDisplay. (mail_display_get_content_location): Gets the current Content-Location CamelURL value. (mail_display_pop_content_location): Pop the Content-Location off the stack. * mail-format.c (get_location): Do URL merging if the Content-Location isn't a full URL. If the Content-Location doesn't exist, pretend the URL is actually the Content-Location URL of our parent multipart (assuming it exists). If that doesn't exist, then yes - return NULL. (handle_multipart_related): Push the Content-Location header value of the multipart/related so that we can do URL merging in get_location() as we process each of the subparts. When we're done, pop it back off the stack. svn path=/trunk/; revision=17113 --- mail/mail-format.c | 93 +++++++++++++++++++++++++++++++++++++----------------- 1 file changed, 64 insertions(+), 29 deletions(-) (limited to 'mail/mail-format.c') diff --git a/mail/mail-format.c b/mail/mail-format.c index 03bd1991c5..54c2df859a 100644 --- a/mail/mail-format.c +++ b/mail/mail-format.c @@ -223,9 +223,9 @@ mail_format_raw_message (CamelMimeMessage *mime_message, MailDisplay *md, static const char * get_cid (CamelMimePart *part, MailDisplay *md) { - char *cid; static int fake_cid_counter = 0; - + char *cid; + /* If we have a real Content-ID, use it.
