Create Gitweb::Config module in 'gitweb/lib/Gitweb/Config.pm' to store all the configuration variables and subroutines regarding the gitweb.perl script. This module depends only on $git_dir from Gitweb::Git and includes the configuration related variables and subroutines (Including those required for configuration of gitweb features) Subroutines moved: evaluate_gitweb_config configure_gitweb_features filter_snapshot_fmts gitweb_get_feature gitweb_check_feature Update gitweb/Makefile to install Gitweb::Config module alongside gitweb Signed-off-by: Pavan Kumar Sunkara <pavan.sss1991@xxxxxxxxx> --- gitweb/Makefile | 1 + gitweb/gitweb.perl | 495 ++---------------------------------------- gitweb/lib/Gitweb/Config.pm | 498 +++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 522 insertions(+), 472 deletions(-) create mode 100644 gitweb/lib/Gitweb/Config.pm diff --git a/gitweb/Makefile b/gitweb/Makefile index 5035c2e..492b0fa 100644 --- a/gitweb/Makefile +++ b/gitweb/Makefile @@ -113,6 +113,7 @@ GITWEB_FILES += static/git-logo.png static/git-favicon.png # Modules: Gitweb::* GITWEB_MODULES += lib/Gitweb/Git.pm +GITWEB_MODULES += lib/Gitweb/Config.pm GITWEB_REPLACE = \ -e 's|++GIT_VERSION++|$(GIT_VERSION)|g' \ diff --git a/gitweb/gitweb.perl b/gitweb/gitweb.perl index 778ac13..b68cc71 100755 --- a/gitweb/gitweb.perl +++ b/gitweb/gitweb.perl @@ -28,6 +28,7 @@ use File::Basename qw(basename); binmode STDOUT, ':utf8'; use Gitweb::Git; +use Gitweb::Config; our $t0; if (eval { require Time::HiRes; 1; }) { @@ -38,7 +39,10 @@ BEGIN { CGI->compile() if $ENV{'MOD_PERL'}; } -our $version = "++GIT_VERSION++"; +# Only configuration variables with build-time overridable +# defaults are listed below.
