From fbf042877dd1690b0202d38cba29c6e7f9f0a0d6 Mon Sep 17 00:00:00 2001 From: zedshaw Date: Mon, 5 Jun 2006 08:54:06 +0000 Subject: Late night hackery. Moving code for checking users and groups to common place, letting people who set allow_concurrency shoot themselves in the foot. git-svn-id: svn+ssh://rubyforge.org/var/svn/mongrel/trunk@225 19e92222-5c0b-0410-8929-a290d50e31e9 --- bin/mongrel_rails | 27 ++++-------------- doc/site/src/docs/apache.page | 2 +- lib/mongrel/command.rb | 66 ++++++++++++++++++++++++++++--------------- lib/mongrel/rails.rb | 9 +++--- 4 files changed, 55 insertions(+), 49 deletions(-) diff --git a/bin/mongrel_rails b/bin/mongrel_rails index 4886e6e..38ec96c 100644 --- a/bin/mongrel_rails +++ b/bin/mongrel_rails @@ -56,31 +56,14 @@ class Start < GemPlugin::Plugin "/commands" valid_dir?
