From b02b2fa3473a8249a8a69eb5cc08ab207503ecd0 Mon Sep 17 00:00:00 2001 From: Tim Potter Date: Sat, 18 Sep 2004 08:41:26 +0000 Subject: r2408: Tridge suggested that all the structures from misc.idl (policy handles, sids, security descriptors and acls) can be automatically generated instead of hand-written. Fix up the swig wrapper generator and helper routines to do this. (Only works for policy handles right now though and arrays are to be converted into lists instead of being binary blobs). Fix up wrapper generation for modules that don't define an interface (e.g misc.idl). (This used to be commit 160dc90921ecc136a25ae88e5c28800ddda5722a) --- source4/build/pidl/swig.pm | 102 ++++++++++++++++++++---------- source4/scripting/swig/dcerpc.i | 134 +--------------------------------------- 2 files changed, 73 insertions(+), 163 deletions(-) diff --git a/source4/build/pidl/swig.pm b/source4/build/pidl/swig.pm index 0b48537d6f..dcd3efa698 100644 --- a/source4/build/pidl/swig.pm +++ b/source4/build/pidl/swig.pm @@ -38,6 +38,21 @@ sub DebugElement($) return $result;
