Description

User-Agent:       
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113

Small problem with an attachement: I just tried to send a php source file and it
got attached with a text/html content type. 
So doing, some email readers choise this "html" content as the main email
content and prevent the receiver to read the real email content.

Reproducible: Always
Steps to Reproduce:
1. Take a simple .php file with a content like "<?php echo 'test' ?>"
2. Create a new email
3. Attach the php file
4. Send/Save this email
5. Check the source of the generated email.

Actual Results:  
Content-Type: text/html;

Expected Results:  
Some possibilities: 
Content-Type: application/x-httpd-php; 
Content-Type: application/octet-stream; 

An other idea is to let it working as is, but add some possibility to change the
type of the attachement.

If you take a look at Outlook generated mime-type for a similar case, it is: 
Content-Type: application/octet-stream; 
that is generated.

Same problem occurs of course using Thunderbird.
Mozilla get's text/html either from the windows registry or from
edit\preferences\Navigator\Helper apps
remove comment#1, Mozilla seems to use the unkown content-decoder (is that right
biesi ?)

I just checked my windows registry, and php files do not have any content-type
associated with.

I got the problem both with mozilla and thunderbird, where no mime-type is
associated with php files.

I will check for this problem on my linux station tomorrow...

doubtful... but I don't know how mailnews does this determination. most likely
seems to be though that it uses the mimeservice to guess from the file...

Just tested on my linux version
-> Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031207

Same problem. 
(a 'file' command on this file reports: PHP script text )

So, it seems for me a mozilla problem.

Setting platform to ALL/ALL since symptom is seen under Linux.

Assuming the way to determine the correct type is found, shouldn't the default 
type be text/php ?

I tried setting up my Windows registry with CLSID\.php pointing to 
CLSID\MIME\DataBase\Content-Type\text/php and vice-versa, but Mozilla ignored 
that.  I also set up the Helper Apps in Mozilla with a text/php type associated 
with .php; that was also ignored on adding the attachment.

Well, this isn't a big deal.  Since they are both text.  This is just
association.  Not a corruption issue (it's not like we are sending binary as
ASCII, or vice versa).

Here's what I see in mail that I sent with a sample php script (note it was sent
from a computer with the content-type set to PHP in the registry):

Content-Type: text/html;
 name="test1.php"
Content-Transfer-Encoding: 7bit
Content-Disposition: inline;
 filename="test1.php"

<?php
// create handle for new PDF document
$pdf = pdf_new();

// open a file
pdf_open_file($pdf, "philosophy.pdf");

// start a new page (A4)
pdf_begin_page($pdf, 595, 842);

// get and use a font object
$arial = pdf_findfont($pdf, "Arial", "host", 1); pdf_setfont($pdf, $arial, 10);

// print text
pdf_show_xy($pdf, "There are more things in heaven and earth, Horatio,",50, 750); 
pdf_show_xy($pdf, "than are dreamt of in your philosophy", 50,730);

// end page
pdf_end_page($pdf);

// close and save file
pdf_close($pdf);
?>


Either way, not a huge deal, but yes, it should most likely be text/php.

HKEY_CLASSES_ROOT\.<extention> is usual key used for content type determination
by Mozilla on MS Windows.
Did you try HKEY_CLASSES_ROOT\.php?
 (Name = Content Type , data = application/x-httpd-php; )

When I defined it for ".dat", Mozilla on Win-2K generated next headers.
 (xxx.dat content is Shift_JIS text) 
> Content-Type: application/x-httpd-php; name="xxx.dat"
> Content-Transfer-Encoding: base64
> Content-Disposition: inline; filename="xxx.dat"

Mike Cowperthwaite, really?
Didn't you enter ".php"(with dot) in Extention field of Helper Applications?
Preceding "dot" should be omitted when Helper Applications.
See my comment of Bug 241821 Comment 5 .

Yes, you are correct -- I did enter it with the dot.  After changing it to 
remove the dot, attaching the .PHP file caused it be generated as a text/php 
attachment.  I then removed the Windows registry items I'd added as a test, and 
restarted Mozilla -- again, attaching the file caused it be text/php.

So, that's the workaround for those of you attaching .php files -- specify the 
MIME type you want (e.g. text/php) in the Helper Apps, and assign it the "php" 
extension.

Thanks, WADA.

can you file a bug about that? it should work both with and without the dot.
component file handling in browser product, please.

Didn't have to file one; bug 170090 was just waiting for confirmation.
