From a9eb90aab5922e08a26c439806c80faa80f7c26d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=98yvind=20A=2E=20Holm?= Date: Tue, 12 Jan 2016 04:31:56 +0100 Subject: gitweb: squelch "uninitialized value" warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit git_object() chomps $type that is read from "cat-file -t", but it does so before checking if $type is defined, resulting in a Perl warning in the server error log: gitweb.cgi: Use of uninitialized value $type in scalar chomp at [...]/gitweb.cgi line 7579., referer: [...] when trying to access a non-existing commit, for example: http://HOST/?p=PROJECT.git;a=commit;h=NON_EXISTING_COMMIT Check the value in $type before chomping. This will cause us to call href with its action parameter set to undef when formulating the URL to redirect to, but that is harmless, as the function treats a parameter that set to undef as if it does not exist.
