echo 'finfo_file(filename, FILEINFO_MIME_TYPE)' . "\n";
$finfo_handle = finfo_open(FILEINFO_NONE, '/usr/share/misc/magic.mgc');
echo finfo_file($finfo_handle, $path, FILEINFO_MIME_TYPE) . "\n";

using the 'magic.mgc' from Fedora don't work this way too (besides it's
practically not useable because of application portability and open_basedir-restrictions outside
php.ini) and may explain why "/usr/bin/php ext/fileinfo/create_data_file.php
/usr/share/misc/magic.mgc > ext/fileinfo/data_file.c" leads to a unusable
'fileinfo.so' extension

i guess some format changed and hence to fork libmagic instead intrudce a shim-layer for
streaming-support and openbase-dir is a historical mistake

I can confirm that even latest master reports
"application/octet-sream" for "php-mimtype-bug.gif" with the
bundled magic.

I can't reproduce this (generating a new data_file.c from Debian
Jessie's magic.mgc, compiling and using finfo works fine for me).
Anyhow, please open another ticket with regard to this issue.
However, it shouldn't be necessary to compile with a custom
magic.mgc, because you could pass a custom magic.mgc directly as
second parameter to finfo_open(). Would that work for you, i.e.
would that produce the expected "image/gif"?

well, in a perfect world on would be able to update 'data_file.c' with the script in the
source tree before compile PHP, in the real world the file is updates, php builds but it don't
work
what about someone takes afte rmore than a year a look why https://access.thelounge.net/harry/php-mimetype-bug.gif
is recognized as application/octet-stream instead image/gif and considers to update the mime
database?
i don't get all the excuses for not use the system libmagic - for open_basedir and
streams-support one would need nothing else than a tiny wrapper doing that all with a tempfile which
ins finally feeded to the system libmagic instead fork it completly
