From 8a7d7aaf810503befc174ce0465a08d086e47b91 Mon Sep 17 00:00:00 2001 From: Petr Viktorin Date: Fri, 24 Feb 2012 12:26:28 -0500 Subject: [PATCH] Defer conversion and validation until after --{add,del,set}attr are handled --addattr & friends that modified attributes known to Python sometimes used converted and validated Python values instead of LDAP strings. This caused a problem for --delattr, which searched for a converted integer in a list of raw strings (ticket 2407). With this patch we work on raw strings, converting only when done. Deferring validation ensures the end result is valid, so proper errors are raised instead of failing later (ticket 2405). Tests included.
