Subject: Fix passing file GLOBs to $c->res->body
X-Git-Tag: 5.80030~24
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=catagits%2FCatalyst-Runtime.git;a=commitdiff_plain;h=f397b3064091f4b9f03210d5b630cfd757534c50

Fix passing file GLOBs to $c->res->body

Contrary to the documentation of Catalyst::Response, passing a
filehandle GLOB did not work, since the content-length header was not
computed correctly.

body checked if it was passed a blessed object and only then use stat
to get the file size. In all other cases the passed thing was considered
a string and length was used. Filehandle GLOBs are neither blessed nor
strings, so the content-length header always got set to 15 (length of a
stringified GLOB: "GLOB(0x123456)").
