Fedora uses IANA as an authoritative source and our mime-types are way behind:

$ diff -uw mime.types.debian mime.types.fedora | diffstat
 mime.types.fedora | 1693 +++++++++++++++++++++++++++++++++++++-----------------
 1 file changed, 1187 insertions(+), 506 deletions(-)

Eg. there are 1693 differences between Fedora and Debian mime.types file.

And something from other side, there is no text/x-python in Fedore
mime.types files...

Ubuntu pull the packages from Debian unstable:

 * Merge from Debian unstable. Remaining changes:
   - Add "cautious-launcher" for handling execution of files that are
     outside /usr and /opt (LP: #506702).
   - Fix typo in cautious-launcher dialog.

That really proves nothing.

BTW Gentoo has even different mime.types file:

Also I don't think you have a definitive say in what associations are
needed in mime-support package. It's up to individual "users" of
mime-support package (read individual packages) to define what they
need for correct functionality. I think of mime-support like kind of
"support" package.

There was nothing rogue about NMU, which fixed RC bug (well, three)
with major impact on PHP users which were opened for more than a half

>> I intend to revert that change

I suggest you explain first how you intend to fix the RC bugs in
mime-support package if you are going to revert the change which fix
confirmed RC bugs.

I think the release team should have a say in that.

Also please write technical reasons why text/x-php (or
application/x-php whatever) is wrong. Unless you can come up with
technical reasons (f.e. it breaks something) please leave it in the
place, as it fixes critical bug (a regression) in processing PHP files
inside apache (and maybe also in other places).

>> unless there there is a solid explanation

It's explained in #670945:

Manifestations of this bug are also described in #661240, #664691.

This is a major regression from squeeze.

It's always good to stick to technical arguments and I say that this
fixes mod_negotiation processing inside an Apache (and possibly other
places), and it fixes major RC bug(s).

Only vaguelly, in fact it's a separate issue with same cause.

We already single out ourselves (Ubuntu really doesn't count).

Thanks, Tomas.

Chris, this is surely not critical severity. I have cloned your bug
report, assigned it a right severity and retitled it to "mime-support:
use of text/ for interpreted languages is discouraged" since we have
several interpreted languages in our mime.types


Fedora has already moved perl to application/x-perl, so basically I
agree with you, but I would suggest we keep all the languages in sync
and move them post release. I would be quite a huge change to mingle
with existing MIME-Types in the freeze.

We might start by syncing MIME-Types with IANA since we are missing
too many new MIME-Type definitions, but again I think it's already too
late in the release cycle to think about that, but again I do not
speak for release team.
