From f7729cdc403a8d4c5a4e9e75e3142bcb51b7250e Mon Sep 17 00:00:00 2001 From: Roeland Jago Douma Date: Sun, 10 Jan 2016 09:59:30 +0100 Subject: [PATCH 1/2] Add composers default autoloader to core This introduces the defacto standard PSR-4 autoloader from composer into core. This will allow proper PSR-4 naming of our classes. Since our original autoloader is still available we can slowly switch over classes to PSR-4. --- composer.json | 8 + lib/base.php | 3 + lib/composer/autoload.php | 7 + lib/composer/composer/ClassLoader.php | 413 ++++++++++++++++++ lib/composer/composer/LICENSE | 21 + lib/composer/composer/autoload_classmap.php | 9 + lib/composer/composer/autoload_namespaces.php | 9 + lib/composer/composer/autoload_psr4.php | 10 + lib/composer/composer/autoload_real.php | 45 ++ lib/composer/composer/installed.json | 1 + 10 files changed, 526 insertions(+) create mode 100644 composer.json create mode 100644 lib/composer/autoload.php create mode 100644 lib/composer/composer/ClassLoader.php create mode 100644 lib/composer/composer/LICENSE create mode 100644 lib/composer/composer/autoload_classmap.php create mode 100644 lib/composer/composer/autoload_namespaces.php create mode 100644 lib/composer/composer/autoload_psr4.php create mode 100644 lib/composer/composer/autoload_real.php create mode 100644 lib/composer/composer/installed.json diff --git a/composer.json b/composer.json new file mode 100644 index 0000000000..98fdb3aa31 --- /dev/null +++ b/composer.json @@ -0,0 +1,8 @@ +{ + "config" : { + "vendor-dir": "lib/composer" + }, + "autoload" : { + "psr-4": {"OC\\": "lib/private"} + } +} diff --git a/lib/base.php b/lib/base.php index 9db4a482f2..3e384f02a2 100644 --- a/lib/base.php +++ b/lib/base.php @@ -516,6 +516,9 @@ class OC { exit(); } + // Add default composer PSR-4 autoloader + require_once OC::$SERVERROOT .
