Hi Mark,
What's interesting is that the same version of File::MMagic works
correctly on a different machine. I suspect that some other module
loaded has changed a global variable that File::MMagic depends on.
Someone has a bug report and patch to that effect here:
http://rt.cpan.org/Public/Bug/Display.html?id=11121
Hmm, if someone is changing $/ without localizing it in a persistent
interpreter like mod_perl or FastCGI, it's pretty much guaranteed to
break something. I don't think File::MMagic should be expected to
defend against that kind of insanity.
File::MMagic is used by Data::FormValidator's "file_format" constraint
for file uploads, so some other people may be using indirectly under
mod_perl as well.
Under mod_perl, it is possible to get this from apache without using
File::MMagic, by using a subrequest. There's some more discussion
here:
http://modperl.com/book/chapters/ch8.html#Reimplementing_I_mod_mime_in_Pe
Could it simply be a matter of fixing the use of the DATA handle, as
Stats suggest here?
Yes, very likely.
