[PATCH 0 of 3] [RFC][CU] Add CIMXML EO parser
by Dan Smith 12 Feb '08

12 Feb '08

This is a first stab. Looking for comments and review. It's pretty raw at the moment, but it does work for me. I still need to do nested objects, but if people are happy with it now, we can bring it into the tree and add the nested bit after that (which would be my preference). Keep your eyes peeled for leaks and broken bits, as I'm sure there are some :)

[PATCH] [RFC] [CU] Turn std_indication's awesome knob to eleven

# HG changeset patch # User Jay Gagnon <grendel(a)linux.vnet.ibm.com> # Date 1202420200 18000 # Node ID 7feaabeb36cea13611d6dc045cd2bd946528032b # Parent 60ecfe23d68caaa9dda1f115289f168ea8f4a297 [RFC] [CU] Turn std_indication's awesome knob to eleven This is the prototype of a new std_indication that will handle Enable/DisableIndications and Activate/DeactivateFilter correctly, even on a per-indication basis when one provider handles more than one indication. Those functions will also now have default_foo equivalents in std_indication, as many providers (especially raise-style ones) will have no special needs there. The hope is that this will *require* minimal change from existing Indicatio providers, but *allow* for code reduction in most, and of course new providers should try to utilize this.
