gitweb: snapshot cleanups & support for offering multiple formats
- Centralize knowledge about snapshot formats (mime types, extensions, commands) in %known_snapshot_formats and improve how some of that information is specified. In particular, zip files are no longer a special case. - Add support for offering multiple snapshot formats to the user so that he/she can download a snapshot in the format he/she prefers. The site-wide or project configuration now gives a list of formats to offer, and if more than one format is offered, the "_snapshot_" link becomes something like "snapshot (_tar.bz2_ _zip_)". - If only one format is offered, a tooltip on the "_snapshot_" link tells the user what it is. - Fix out-of-date "tarball" -> "archive" in comment. Alert for gitweb site administrators: This patch changes the format of $feature{'snapshot'}{'default'} in gitweb_config.perl from a list of three pieces of information about a single format to a list of one or more formats you wish to offer from the set ('tgz', 'tbz2', 'zip'). Update your gitweb_config.perl appropriately. There was taken care for old-style gitweb configuration to work as it used to, but this backward compatibility works only for the values which correspond to gitweb.snapshot values of 'gzip', 'bzip2' and 'zip', i.e. ['x-gzip', 'gz', 'gzip'] ['x-bzip2', 'bz2', 'bzip2'] ['x-zip', 'zip', ''] The preferred names for gitweb.snapshot in repository configuration have also changed from 'gzip' and 'bzip2' to 'tgz' and 'tbz2', but the old names are still recognized for compatibility.
