mimestub.c --- junk to let libmime.a be tested standalone.
|
||
|
||
The junk in this file is various bits and pieces that have been
|
||
cut-and-pasted from other places in Mozilla, mainly netlib. We just
|
||
copied these functions to avoid pulling in the spaghetti that is netlib,
|
||
and libxp, and libmsg, and and and...
|
||
|
||
In addition to this file, we link directly against lib/xp/xp_file.o,
|
||
lib/xp/xp_str.o, and lib/libmsg/addr.o, because those files *actually
|
||
stand on their own*!
|
||
|
||
Life kinda sucks, but oh well.

If the base URL, `absolute_url', is a "mailbox:" URL, then

we should not allow relative expansion: that is,

||
NET_MakeAbsoluteURL("mailbox:/A/B/C", "YYY") should not
|
||
return "mailbox:/A/B/YYY".
|
||
|
||
However, expansion of "#" and "?" parameters should work:
|
||
NET_MakeAbsoluteURL("mailbox:/A/B/C?id=XXX", "#part2")
|
||
should be allowed to expand to "mailbox:/A/B/C?id=XXX#part2".
|
||
|
||
If you allow random HREFs in attached HTML to mail messages to
|
||
expand to mailbox URLs, then bad things happen -- among other
|
||
things, an entry will be automatically created in the folders
|
||
list for each of these bogus non-files.
|
||
|
||
It's an open question as to whether relative expansion should
|
||
be allowed for news: and snews: URLs.
|
||
|
||
Reasons to allow it:
|
||
|
||
= ClariNet has been using it
|
||
|
||
= (Their reason:) it's the only way for an HTML news message
|
||
to refer to another HTML news message in a way which
|
||
doesn't make assumptions about the name of the news host,
|
||
and which also doesn't assume that the message is on the
|
||
default news host.
|
||
|
||
Reasons to disallow it:
|
||
|
||
= Consistency with "mailbox:"
|
||
|
||
= If there is a news message which has type text/html, and
|
||
which has a relative URL like <IMG SRC="foo.gif"> in it,
|
||
but which has no <BASE> tag, then we would expand that
|
||
image to "news:foo.gif". Which would fail, of course,
|
||
but which might annoy news admins by generating bogus
|
||
references.
|
||
|
||
So for now, let's allow
|
||
NET_MakeAbsoluteURL("news:123@4", "456@7") => "news:456@7"; and
|
||
NET_MakeAbsoluteURL("news://h/123@4", "456@7") => "news://h/456@7".
