From 2d7a3532c78bace2f3631ab0e594f713dcab9916 Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Thu, 2 Oct 2008 16:50:04 +0200 Subject: [PATCH] gitweb: Fix two 'uninitialized value' warnings in git_tree() If we did try to access nonexistent directory or file, which means that git_get_hash_by_path() returns `undef`, uninitialized $hash variable was passed to 'open' call. Now we fail early with "404 Not Found - No such tree" error. (If we try to access something which does not resolve to tree-ish, for example a file / 'blob' object, the error will be caught later, as "404 Not Found - Reading tree failed" error). If we tried to use 'tree' action without $file_name ('f' parameter) set, which means either tree given by hash or a top tree (and we currently cannot distinguish between those two cases), we cannot print path breadcrumbs with git_print_page_path(). Fix this by moving call to git_print_page_path() inside conditional. Signed-off-by: Jakub Narebski Acked-by: Petr Baudis Signed-off-by: Shawn O.
