RE: [cdt-dev] Custom Builders Migrating to New CDTProjectModel[Bug115935]

hi Warren,
> Can this
file be configuration rather than project specific?
I remember this being discussed
at the fall conference, and would like to try and summarize what was said
1) re-indexing per-configuration
would be prohibitively expensive. Maintaining separate files would still
require an initial reindex per configuration, or on adding a new configuration.
I
don't think we have a bugzilla for this if you wanted to revisit it
2) it was suggested that a configuration
is nominated as the "indexing configuration", and this could
be changed by the user as a preference as a compromise.
3) Leo suggested that the indexing
API could still take ICConfiguration's as parameters from the client code,
even if the indexing backend doesn't act on them. We've not done this at
present, but I think it makes sense.
This issue is also part of a more general
question about what statements we can make about guarantees on the accuracy
of the contents of the index e.g. see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=154563
(we can fix this)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=165696
https://bugs.eclipse.org/bugs/show_bug.cgi?id=171834
From an offline/pre-built index slant
(74433), I'm interested in allowing offline indexes to be potentially configuration
dependent. This is inaccurate in the same way as 171834, but is something
ISV's might want to enable if its appropriate for their environment.
thanks,
Andrew
