Bug #124226 for MIME-Types: Suboptimal choice of mime types?

Subject:

Suboptimal choice of mime types?

With the latest 2.16 a number of CPAN modules started to fail their test suites. For example, in the Dancer-1.3202 distribution the following tests fail: ... # Failed test 'a mime_type is found with MIME::Types' # at t/04_static_file/01_mime_types.t line 16. # got: 'application/vnd.easykaraoke.cdgdownload' # expected: 'application/zip' # Looks like you failed 1 test of 10. t/04_static_file/01_mime_types.t .................... Dubious, test returned 1 (wstat 256, 0x100) Failed 1/10 subtests ... # Failed test 'mime_type can be forced' # at t/06_helpers/01_send_file.t line 83. # got: 'image/vnd.mozilla.apng' # expected: 'image/png' # Looks like you failed 1 test of 25. t/06_helpers/01_send_file.t ......................... Dubious, test returned 1 (wstat 256, 0x100) Failed 1/25 subtests ... Looking at the results it seems that instead of the widely used image/png now image/vnd.mozilla.apng is returned, similar in the case of application/zip. A similar problem is in the Catalyst-Controller-Imager-0.06 test suite (see CPAN RT #124225). The problem in App-revealup-0.21 (see https://github.com/yusukebe/App-revealup/issues/11 ) looks acceptable to me --- formerly image/x-bmp was expected, now it's image/bmp.

Another one: MRGRIPH/Archive-Any-Plugin-Rar-0.02.tar.gz The test t/explicit-type.t fails here with MIME-Types 2.17. It seems that the module expects application/x-rar, but gets application/vnd.rar (Though if you think that "vnd" is better than "x-", then maybe the module has to adapt?)

That should be fixed with 2.17. It is not easy to automatically determine which mime-type has preference for a certain extension. The logic has improved a little over 2.16. Show quoted text

IANA had changed their way of presenting information: the files which I parsed are frozen for 4 years, I discovered last week... now I use different ways to extract the official info from them, which resulted in 30% more types and extensions... "application/vnd.rar" is the officially assigned IANA type, so no chance that I move back to "application/x-rar". Regression tests which contain mime-types can easily break: it is an external moving target... -- As always: I am greatful for your testing and maintenance effort!
