From bug #64704: Necko needs to be more intelligent about setting the file type from the mimetype rather than relying on the file extension. The front-end should avoid content sniffing. DougT notes: Necko provides the content type via the nsIChannel, and there is a MIME service for getting the content type for an extension.

we do are best. if the http server does not set the mimetype, and the file does not have an extension, there is nothing we can do. Please see my comment in bug 64704. Marking INVALID

There is something we can do. We can look at the file contents. We should be able to reliably identify HTML, JPEG, GIF, and lots of other file types this way.

i understand... crack the file open and guess what it is. I thought that we do that somewhere... maybe layout... So, given a very small buffer of the file, we need to ask the mime service if it known what the file is.
Target Milestone: --- → mozilla1.0
we already parse unknown files using nsUnknownDecoder.cpp which is a stream converter that is envoked in nsURILoader.cpp. the order of precedence is (winning-most at the top)... - HTTP MIME-type from the server - file extension to mime type mapping. Uses nsMIMEService which maintains our own hard coded list of extensions to MIME types (or IP config on the mac) - byte sniffing in the uri loader (front end, nsUnknownDecoder.cpp) if someone has a better model, please step up w/ it.
mass move, v2. qa to me.

what is milestone "mozilla1.0" anyway? Moving to future.
Target Milestone: mozilla1.0 → Future
I'm going to resolve this, b/c I can't think of a better way of doing this. There are various bugs on places people think we should DO this and we don't (like opening file URL's w/ no extensions in the file name. The actual content determination approach seems solid to me.
