From 559c76f761ff46c0d0e7f679d24d7ca5304db101 Mon Sep 17 00:00:00 2001 From: Rob Crittenden Date: Thu, 27 Aug 2009 14:12:55 -0400 Subject: Add option to the installer for uid/gid starting numbers. This also adds a new option to the template system. If you include eval(string) in a file that goes through the templater then the string in the eval will be evaluated by the Python interpreter. This is used so one can do $UIDSTART+1. If any errors occur during the evaluation the original string is is returned, eval() and all so it is up to the developer to make sure the evaluation passes. The default value for uid and gid is now a random value between 1,000,000 and (2^31 - 1,000,000) --- ipapython/ipautil.py | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'ipapython') diff --git a/ipapython/ipautil.py b/ipapython/ipautil.py index 240e0d87..47b651c1 100644 --- a/ipapython/ipautil.py +++ b/ipapython/ipautil.py @@ -68,7 +68,15 @@ def realm_to_suffix(realm_name): return ",".join(terms) def template_str(txt, vars): - return string.Template(txt).substitute(vars) + val = string.Template(txt).substitute(vars) + + # eval() is a special string one can insert into a template to have the + # Python interpreter evaluate the string.
