We often add *.os files into maniphest tasks. These files comes from an internal document managment system. Apache is configured to handle these files as attachments:

<LocationMatch "\.(?i:os)$">
    ForceType application/octet-stream
    Header set Content-Disposition attachment

These settings worked for about 2 years now.

But now I noticed some weird behavior while downloading files with '*.os' extension. While downloading files with this extension via chrome the extension changes to *.txt

I've already tested it with a bank new system + apache 2.4 and these setting. It works. So it seems to be a problem with phabricator and how it delivers the files.

Reproduction Steps

  • Browse to a maniphest tasks containing a *.os file.
  • Download the file using the Link it fails:

  • Downloading the file in the files app it works:

  • OS File for testing:

(Seems to work here) ...very strange 😠

Removed apache settings:

<LocationMatch "\.(?i:os)$">
    ForceType application/octet-stream
    Header set Content-Disposition attachment

Works now for Downloading. Doesn't work with 'View File' action in Files.

If this is the supposed behavior it is fine for me.
