From a781785d8f1eb7adf05a24b121104716a086a67a Mon Sep 17 00:00:00 2001 From: Jakub Narebski Date: Sun, 22 Jul 2007 23:41:20 +0200 Subject: [PATCH] gitweb: Fix support for legacy gitweb config for snapshots Earlier commit which cleaned up snapshot support and introduced support for multiple snapshot formats changed the format of $feature{'snapshot'}{'default'} (gitweb configuration) and gitweb.snapshot configuration variable (repository configuration). It supported old gitweb.snapshot values of 'gzip', 'bzip2' and 'zip' and tried to support, but failed to do that, old values of $feature{'snapshot'}{'default'}; at least those corresponding to old gitweb.snapshot values of 'gzip', 'bzip2' and 'zip', i.e. ['x-gzip', 'gz', 'gzip'] ['x-bzip2', 'bz2', 'bzip2'] ['x-zip', 'zip', ''] This commit moves legacy configuration support out of feature_snapshot subroutine to separate filter_snapshot_fmts subroutine. The filter_snapshot_fmts is used on result on result of gitweb_check_feature('snapshot'). This way feature_snapshot deals _only_ with repository config. As a byproduct you can now use 'gzip' and 'bzip2' as aliases to 'tgz' and 'tbz2' also in $feature{'snapshot'}{'default'}, not only in gitweb.snapshot. While at it do some whitespace cleanup: use tabs for indent, but spaces for align.
