From 77a2870186d3b10ea15ba5e001e7a703f0a5ccaf Mon Sep 17 00:00:00 2001 From: Amin Azez Date: Fri, 1 Feb 2008 16:19:36 +0000 Subject: Samba4 poor mans debug_ctx() DEBUG(), DEBUGADD() and friends can now use debug_ctx() in the formatting expressions again, e.g. DEBUG(5,("Guid failed to match: %s\n", GUID_string(debug_ctx(), r->guid))); Sadly it's done with macros (again) but when we need to save the 8 or 16 bytes of object code per DEBUG() expression we can do it the Samba 3 way with added thread-safety for Samba 4. That could save up to 200K, allowing 12 bytes for each occurrance of DEBUG...
