There were some modules that did not offer "or (at your option) any
later version" in their license and these had to be left alone.
This should solve the incorrect FSF address issue #4 on GitHub.
As we derive a lot of filenames from strings in UTF-8 encoded files, we
need to make sure that any filename that might might be set by a user –
including all the filenames containing a directory deriving from
$DataDir – are passed through utf8::encode. That is, every character
gets replaced with a sequence of one or more characters that represent
the individual bytes of the character and the UTF8 flag is turned off.
In other words, -d $DataDir might not work if $DataDir contains a UTF-8
encoded string. The solution is to use the following replacements:
-f $name IsFile($name)
-e $name IsFile($name)
-d $name IsDir($name)
(stat($name))[9] Modified($name)
-M $name $Now - Modified($name)
-z $name ZeroSize($name)
unlink $name Unlink($name)
mkdir $name CreateDir($name)
rmdir $name RemoveDir($name)
(Using IsFile for -e is probably not ideal?)
If you don’t, and Oddmuse gets used with Mojolicious, and you use the
Namespaces Extension, and a namespace contains non-ASCII characters such
as ä, ö, or ü, these characters will end up as part of $DataDir and
trigger the problem.
I also wonder whether we should be using some other Perl library.
Replaced the $Id$ tags in $WikiDescription for all the modules and wiki.pl itself with a link to the source and an appropriate wiki page, if possible. This is shown in action=version and should help users figure out what another wiki has installed.
