From e72c0eaf9bbdb2a9467f3f026b39b1c1755c1105 Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Mon, 7 May 2007 01:10:05 +0200 Subject: [PATCH] gitweb: Add combined diff support to git_patchset_body Calling convention for combined diff similar to the one for git_difftree_body subroutine: difftree info (first parameter) must be result of calling git-diff-tree with -c/--cc option, and all parents of a commit must be passed as last parameters. See also description in "gitweb: Add combined diff support to git_difftree_body" This ability is not used yet. Generating "src" file name for renames in combined diff was separated into fill_from_file_info subroutine; git_difftree_body was modified to use it. Currently git_difftree_body and git_patchset_body fills this info separately. The from-file line in two-line from-file/to-file header is not hyperlinked: there can be more than one "from"/"src" file. This differs from HTML output of ordinary (not combined) diff. format_diff_line subroutine needs extra $from/$to parameters to format combined diff patch line correctly.
