1340246 - bug: Multi-extension parsing problem

Status: RESOLVED INVALID

(Firefox :: Untriaged, defect)

Description

[nailyk]

Attachment: capture.pdf

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20161213204132

Steps to reproduce:

I provide LineageOS roms. At build end you get two files: 
cm-12.1-20170213-nailyk-z3c.zip
cm-12.1-20170213-nailyk-z3c.zip.md5sum
both are auto pushed to a h5ai script ( https://crusader.synhacx.eu.org/releases/cm-12.1/ )
Into Firefox I set download as "always ask", for convenient purpose, but same behavior happens when downloads are 'auto-opened'. 

1. Click on the zip.md5sum file, a popup to select action get opened, 
2. Select open with notepad/mousepad/gedit/any text editor & 'always use this action', (capture 1)
3. click on the zip file, it will download and will be open with your text editor. (capture 2)

Capture 3 & 4 are Application settings. 

Tested on win7x64 FF51.0.1, Debian 8 FF 45.6.0, xubuntu 16.10 (FF version not checked)
P.S.: add.zip(.md5sum) on https://crusader.synhacx.eu.org/releases/cm-12.1/ are for this issue, preventing opening a 300Mb zip into a text editor. 


Actual results:

'zip' file extension and 'zip.md5sum' are handled on the same way ('zip')


Expected results:

'zip' file extension and 'zip.md5sum' are handled uniquely.

It's more like an issue in server configuration.

Here's response header for cm-12.1-20170213-nailyk-z3c.zip.md5sum:
  Date: Thu, 16 Feb 2017 18:53:42 GMT
  Server: Apache
  Last-Modified: Mon, 13 Feb 2017 04:21:07 GMT

  Accept-Ranges: bytes

  Keep-Alive: timeout=5, max=100
  Connection: Keep-Alive
  Content-Type: application/zip

and response header for cm-12.1-20170213-nailyk-z3c.zip:
  Date: Thu, 16 Feb 2017 18:53:28 GMT
  Server: Apache
  Last-Modified: Mon, 13 Feb 2017 04:21:07 GMT
  Etag: "11fbf122-54861c6bf560b"
  Accept-Ranges: bytes
  Content-Length: 301723938
  Keep-Alive: timeout=5, max=99
  Connection: Keep-Alive
  Content-Type: application/zip

The server returns "Content-Type: application/zip" for both files.
That's the reason why Firefox passes those files to same handler, associated with application/zip type.

At least returning application/zip for md5sum file doesn't sound right.
I guess you need to configure the server to return text/plain or something for it.

Really sorry. 
As it isn't the only website where this problem happens I though it was a Firefox issue. 
Closing now.
