From b0be3838bb75e8b3be04310cc379142c3ef65703 Mon Sep 17 00:00:00 2001 From: Giuseppe Bilotta Date: Tue, 21 Oct 2008 21:34:53 +0200 Subject: gitweb: parse parent..current syntax from PATH_INFO This patch makes it possible to use an URL such as project/action/somebranch..otherbranch:/filename to get a diff between different version of a file. Paths like project/action/somebranch:/somefile..otherbranch:/otherfile are parsed as well. All '*diff' actions and in general actions that use $hash_parent[_base] and $file_parent (e.g. 'shortlog') can now get all of their parameters from PATH_INFO Signed-off-by: Giuseppe Bilotta Acked-by: Jakub Narebski Signed-off-by: Junio C Hamano --- gitweb/gitweb.perl | 36 ++++++++++++++++++++++++++++++++++-- 1 file changed, 34 insertions(+), 2 deletions(-) (limited to 'gitweb') diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl index f8021da967..3d62019e1f 100755 --- a/gitweb/gitweb.perl +++ b/gitweb/gitweb.perl @@ -549,7 +549,12 @@ sub evaluate_path_info { 'history', ); - my ($refname, $pathname) = split(/:/, $path_info, 2); + # we want to catch + # [$hash_parent_base[:$file_parent]..]$hash_parent[:$file_name] + my ($parentrefname, $parentpathname, $refname, $pathname) = + ($path_info =~ /^(?:(.+?)(?::(.+))?\.\.)?(.+?)(?::(.+))?$/); + + # first, analyze the 'current' part if (defined $pathname) { # we got "branch:filename" or "branch:dir/" # we could use git_get_type(branch:pathname), but: @@ -564,7 +569,13 @@ sub evaluate_path_info { $input_params{'action'} ||= "tree"; $pathname =~ s,/$,,; } else { - $input_params{'action'} ||= "blob_plain"; + # the default action depends on whether we had parent info + # or not + if ($parentrefname) { + $input_params{'action'} ||= "blobdiff_plain"; + } else { + $input_params{'action'} ||= "blob_plain"; + } } $input_params{'hash_base'} ||= $refname; $input_params{'file_name'} ||= $pathname; @@ -584,6 +595,27 @@ sub evaluate_path_info { $input_params{'hash'} ||= $refname; } } + + # next, handle the 'parent' part, if present + if (defined $parentrefname) { + # a missing pathspec defaults to the 'current' filename, allowing e.g. + # someproject/blobdiff/oldrev..newrev:/filename + if ($parentpathname) { + $parentpathname =~ s,^/+,,; + $parentpathname =~ s,/$,,; + $input_params{'file_parent'} ||= $parentpathname; + } else { + $input_params{'file_parent'} ||= $input_params{'file_name'}; + } + # we assume that hash_parent_base is wanted if a path was specified, + # or if the action wants hash_base instead of hash + if (defined $input_params{'file_parent'} || + grep { $_ eq $input_params{'action'} } @wants_base) { + $input_params{'hash_parent_base'} ||= $parentrefname; + } else { + $input_params{'hash_parent'} ||= $parentrefname; + } + } } evaluate_path_info(); -- cgit v1.2.3
