Once upon a time, Red Hat had a patch to add a '-P' option to gdb, which would put it directly into Python scripting. I think maybe I wrote it ages ago, but then when Andrew tried to submit it upstream, I basically rejected it. That was a mistake on my part. IIRC he had a pretty good counter-argument at the time, I don't recall why I didn't recant. Another option I looked at, way back when, was to compile gdb with -fPIE and let it be loaded as a shared library. The idea here was that, with a few other tweaks, ordinary Python code could just 'import gdb'. Anyway, I guess now I'd support either of these. 'import gdb' would be great to have, even with its various limitations. However it's a bit trickier to get working than just resurrecting the old -P patch. Tom
