This contains 3 messages
1: Original mesage with a attachment which filename contains Japanese

3: Attachment is detached to
   (in Japanese: C:/Documents%20and%20Settings/level/¥Ç¥¹¥¯¥È¥Ã¥×/ )

In Japanese environment, detach can not be used because of this bug.
Comment 3 Asa Dotzler [:asa] 2005-09-13 09:27:43 PDT
Scott, this seems like a pretty big failure in a new feature. Will you guys have
time to look into this for 1.5 b2?
Comment 4 Scott MacGregor 2005-09-13 09:29:10 PDT
yes we should fix this

fix for problem noticing that detach failed.

I had a problem even detaching the attachment in the provided test case, so
I've fixed that handling of that error.  I think the filename was what caused
the problem detaching.

I'm not convinced the problem reported has to do with filenames - it could just
have to do with that we've left the content type as base64 encoded, when it's
not, since we decode when we do a save as.
Comment 6 David :Bienvenu 2005-09-13 13:14:21 PDT
see bug 308321 for the encoding issue.
Comment 7 David :Bienvenu 2005-09-14 09:35:33 PDT
Hideyuki, can you try with tomorrow's build, and see if it was the content
transfer encoding that caused the problem? I can't test with japanese characters
Comment 8 u69748 2005-09-15 08:53:37 PDT
I have tried with 1.5 Beta 1 (20050915).

The problem is not fixed.
Detached part is following.

Content-Type: text/plain;
Content-Disposition: attachment; filename="���������.txt"
X-Mozilla-Altered: AttachmentDetached; date="Fri Sep 16 00:40:14 2005"

The original MIME headers for this attachment are:
Content-Type: text/plain;
Content-Transfer-Encoding: base64
Content-Disposition: inline;


Still I cannot open the file.
And error page says:

File Not Found
The file /C:/Documents and Settings/level/ƒfƒXƒNƒgƒbƒv/ƒeƒXƒg.txt cannot be
found. Please check the location and try again.

BTW, I think this error page is not suitable for this case.
Comment 9 u69748 2005-09-15 09:07:19 PDT
(In reply to comment #8)
> X-Mozilla-External-Attachment-URL:

Firefox can open the detached file by this URL.
Comment 10 David :Bienvenu 2005-09-15 21:56:10 PDT
Jungshik, any ideas about this? Presumably it's a filename escaping problem...
Comment 11 Masayuki Nakano [:masayuki] (Mozilla Japan) 2005-09-18 23:11:46 PDT
I think that this is a bug.

> 589     if(webNav)

URI string

> 592       nsnull,                               // Referring URI
> 593       nsnull,                               // Post stream
> 594       nsnull);                              // Extra headers
> 595   }

I will test tonight or later.

I think that we don't need to unescape the URL for nsIWebNavigation::LoadURI.
This patch makes to open the detached file. But the description is broken. This
is another bug.

I tried this on imap and pop3, and it worked fine on my test cases. Thx for the
patch! Scott, do you have some interesting test cases for this?

Patch rv1.0

I'm not a huge fan of adding the early returns to the code, I thought the old
organization was better. But using ConvertASCIItoUTF16 looks good to me. 

approving for the branch too.
