[Note: This is solved in the respect that I got it to function. But how I got it to function is undesirable.]
Ok the component is working on the Cook sandbox, but it is not working on my dev server. The component will not allow me to upload a zip file on my own dev server. I get this error:
Mime type not valid (application/force-download), allowed Mimes are application/x-gzip - application/x-tar - text/plain - application/x-zip - application/x-compressed - application/x-zip-compressed :
Impossible to upload file : license.zip
So, I checked the Joomla mime types and added all of the different mime types for zip files on my dev server. Well, that didn't matter. Same error.
So I tried uploading a text file. (txt) Same problem.
I made sure that the MIME types are selected in the File properties on the table view in Cook.
What am I missing? I read the other articles about MIME types, but I'd rather not hack core files to get around this problem.
Ideas?
Note: No PHP errors are being generated on my dev server.
Joomla 2.5.7
PHP 5.3.18
DB Automatisms: Table
Cook: v2.0

administrator/components/com_sgm/classes/upload.php
If I comment out this section:
$this->file->mime = $this->getMime($this->file->tmp);
if (!$this->checkMime($this->file->mime))
{
$app->enqueueMessage(JText::sprintf( "SGM_UPLOAD_MIME_TYPE_NOT_VALID_ALLOWED_MIMES_ARE",
$this->file->mime,
$this->getAllowedMimes()), 'error');
return false;
}
The upload works, but the file doesn't get the correct extension when stored.

Might have the solution. My version of Apache was compiled without MIME Magic. I am recompiling now and will post results.
Update: Recompiled with MIME Magic enabled. No change. Same error.

Ok, I went through the functions used in Cook to figure out why this wasn't working. In short, none of the methods in the functions were able to find an available PHP function. (My server is locked down pretty tight. Only stuff that is needed is enabled.)
Some notes:
mime_content_type is deprecated in PHP 5.3.+
finfo_file isn't as standardized as anyone would like it to be
system, shell_exec, and exec are typically disabled on my servers for really good reasons
So, if I have to pick one, I will go with shell_exec. I enabled it and the MIME detection now works correctly. So, what I am going to do now is recompile apache with Fileinfo enabled and try it. I will post the results. Hopefully it works so I can disable shell_exec again.

Ok, I recompiled apache again with finfo_file support. It is enabled and functioning.
I disabled shell_exec and tried uploading a file again.
Mime type not valid (application/zip), allowed Mimes are application/x-gzip - application/x-tar - text/plain - application/x-zip - application/x-compressed - application/x-zip-compressed :
Impossible to upload file : license.zip
So for now I will enable shell_exec so it will work, but hopefully the finfo_file will one day work.

Have you tried overwriting the file name with {mimext} and other options? Check what's available and have a little play around...

P.S. Karma+1 for all your hard work debugging this and providing thorough explanation of your findings - i hope others might find this useful!!!
PPS Did you find BTB3000's post on mime types and if so, was it useful?

Yes, all of the MIME features now work since I enabled shell_exec.
What I would like @admin to figure out is why finfo_file does not appear to be working. I enabled it, disabled shell_exec, and the upload failed. However, the function is available and working on my dev server.

Do you mean on your server or cook sandbox? IF cook, then maybe it's running on < php 5.3 which is required.
If this is on your server, is it possible that there is some global that you are not actually able to override? Are you in php.ini or setting it programmatically?
BTW - not sure if this will be much help as the thread is not solved however, it may give you some other ideas...

On my server. My PHP version is 5.3.18.
Yes, I read that article. In short, the error for both of us was in the PHP configuration. Well, an error in the sense that what needs to be enabled for this to work correctly in Cook.

Since ... is depreceated in PHP5.3, for the moment, won't something like this work @admin; function checkMimeType($filename)
{
$mimetype = false;
if(function_exists('finfo_fopen')) {
// open with FileInfo
} elseif(function_exists('getimagesize')) {
// open with GD
} elseif(function_exists('exif_imagetype')) {
// open with EXIF
} elseif(function_exists('mime_content_type')) {
$mimetype = mime_content_type($filename);
}
return $mimetype;
}
Alternatively, what about checking for the php version using phpversion(); then calling the functions accordingly?

In the source, it is more or less the same. The difference with cook is that you can custom the functions calls to use in a simple array, and/or test them in a different order.
As you said, it can be handled with version of PHP, even better.
And for 5.3.x, somebody has an answer ?
Not tested with "exif_imagetype". Does work on 5.3 ?

Not sure about exif_imagetype but isn't the finfo_fopen function the way to do it in 5.3?
