This is second part of removing gitweb dependency on external diff (used in git_diff_print). Get rid of git_diff_print invocation in git_blobdiff, and use either git-diff-tree (when both hash_base and hash_parent_base are provided) patch format or git-diff patch format (when only hash and hash_parent are provided) for output. Supported URI schemes, and output formats: * New URI scheme: both hash_base and hash_parent_base (trees-ish containing blobs versions we want to compare) are provided. Also either filename is provided, or hash (of blob) is provided (we try to find filename then). For this scheme we have copying and renames detection, mode changes, file types etc., and information extended diff header is correct. * Old URI scheme: hash_parent_base is not provided, we use hash and hash_parent to directly compare blobs using git-diff. If no filename is given, blobs hashes are used in place of filenames. This scheme has always "blob" as file type, it cannot detect mode changes, and we rely on CGI parameters to provide name of the file. Added git_to_hash subroutine, which transforms symbolic name or list of symbolic name to hash or list of hashes using git-rev-parse. To have "blob" instead of "unknown" (or "file" regardless of the type) in "gitweb diff header" for legacy scheme, file_type function now returns its argument if it is not octal string. Added support for fake "2" status code in git_patchset_body. Such code is generated by git_blobdiff in legacy scheme case. ATTENTION: The order of arguments (operands) to git-diff is reversed (sic!) to have correct diff in the legacy (no hash_parent_base) case. $hash_parent, $hash ordering is commented out, as it gives reversed patch (at least for git version 1.4.1.1) as compared to output in new scheme and output of older gitweb version.

GIT web Interface The one working on: http://www.kernel.org/git/ From the git version 1.4.0 gitweb is bundled with git. How to configure gitweb for your local system: You can specify the following configuration variables when building GIT: * GITWEB_SITENAME Shown in the title of all generated pages, defaults to the servers name. * GITWEB_PROJECTROOT The root directory for all projects shown by gitweb. * GITWEB_LIST points to a directory to scan for projects (defaults to project root) or to a file for explicit listing of projects. * GITWEB_HOMETEXT points to an .html file which is included on the gitweb project overview page. * GITWEB_CSS Points to the location where you put gitweb.css on your web server. * GITWEB_LOGO Points to the location where you put git-logo.png on your web server. * GITWEB_CONFIG This file will be loaded using 'require'. If the environment $GITWEB_CONFIG is set when gitweb.cgi is executed the file in the environment variable will be loaded instead of the file specified when gitweb.cgi was created.
