Re: [gmime-devel] Feature request: custom content headers

[evil legacy <evil legacy gmail com>]

Example mime:

To: <foo example com>
Subject: foo bar
MIME-Version: 1.0
Content-Type: multipart/mixed;
 boundary="----------64FE7F17715"

------------64FE7F17715
Content-Type: text/html; charset=random
Content-Transfer-Encoding: 8bit
W-Storage: @36F60000000217E4C8A1
W-Size: 5161

------------64FE7F17715
Content-Type: text/html; charset=random
Content-Transfer-Encoding: 8bit
W-Storage: @36F60000000217E4CFE0
W-Size: 1337

------------64FE7F17715--

And when doing g_mime_object_get_header(part, 'W-Storage') it's being ignored.

So in gmime-part.c, gmime-message.c and gmime-message-part.c, I've
changed all the:

if (!g_ascii_strncasecmp ("Content-", header, 8))

to

if (!g_ascii_strncasecmp ("Content-", header, 8) ||
!g_ascii_strncasecmp("W-", header, 2))

and

if (g_ascii_strncasecmp ("Content-", header, 8) != 0)

to

if (g_ascii_strncasecmp ("Content-", header, 8) != 0 &&
g_ascii_strncasecmp ("W-", header, 2) != 0)

when appropriate.

Of course a more general solution would be to loop over an array of
headers, which by default has 'Content-' and user can append other
headers to.

BTW, I've seen that the mime GMail produces also have non Content-, If
you forward yourself an email from GMail that has attachments, you'll
see that each attachment part has a header that looks like so:

X-Attachment-Id: 94b0d466d277289b_0.0

Thanks
