| I just compiled and installed the new version but found that "file" has at
| least now problems with PHP files.
|
| Calling "file" for e.g. for the file wordpress/wp-admin/about.php of
| the tarball wordpress-4.5.tar.gz I got the following results:
|
| file 5.26: , version .
|
| file 5.25: PHP script, ASCII text, with very long lines
|
| Checking other PHP files (also from other packages) I got mostly similar
| results. In very rare cases "file 5.26" issues correctly as before "PHP
| script, ASCII text", in some rare other cases incorrectly "C++ source,
| ASCII text" instead of the correct "PHP script, ASCII text".
|
| No idea if I did something wrong or it's a bug.
|
| Regards
|
| Jens
|
| P.S.: Just for info: The above mentioned "arbitrary" file is directly
| available for e.g. under
|
| http://fossies.org/linux/www/wordpress-4.5.tar.gz/wordpress/wp-admin/about.php?m=b
Unfortunately some new magic is problematic; here's a patch.

- Update to file version 5.27
* Errors comparing DER entries or computing offsets
are just indications of malformed non-DER files.
Don't print them.
* Offset comparison was off-by-one.
* Fix compression code (Werner Fink)
