I’m not sure there’s much to worry about with pickle. I think the biggest issue is that in IronPython we’ll serialize strings as Unicode where CPython would serialize them as ASCII strings. Once they’re deserialized though everyone should treat them (mostly) the same.
I use pickle to store the completion database for PTVS – there I have CPython and IronPython writing the files and I have a modified version of IronPython’s cPickle implementation to also read/write them from PTVS. I don’t really do much reading from the CPython side in the product, but I do it all the time for debugging. I haven’t run into any issues with it.

Super cool. But what about pickle do u need to watch out for? Due to the Rhino infrastructure it seems difficult to impossible to really debug an IronPython script hosted within rhino, so tracing low level bugs will be a nightmare.

Makes more sense. Sounds like I'll be pickling objects back and forth between cpy and ipy.

The compatibility is in most of the standard library, pycurl is not part of the standard library. There are even issues in parts of the standard library as you can see if you look at the bug tracker on CodePlex. slide On Wed, Feb 22, 2012 at 2:43 PM, Lucas Vickers <lucasvick...@gmail.com<mailto:lucasvick...@gmail.com>> wrote: Hello, I am OS X and I am working with a pre-compiled version of IronPython (it is hosted by Rhino 3d to be specific). I am attempting to import standard CPython libraries, such as pycurl. I am confused as the FAQ states compatibility between IronPython 2.7 and CPython 2.7, but using the following code which works on CPython 2.7.2 fails on IronPython 2.7.0. sys.path[0:0] = [ '/Users/lucasvickers/.virtualenvs/rhino/lib/python2.7/site-packages' ] import pycurl It claims no module pycurl. A little more reading shows attempts to allow linkage between IronPython and CPython such as ironclad (http://code.google.com/p/ironclad/ ), but then why the claimed compatibility in the first place? Can anyone help me understand? thanks Lucas _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org<mailto:Ironpython-users@python.org> http://mail.python.org/mailman/listinfo/ironpython-users -- Website: http://earl-of-code.com -- Website: http://earl-of-code.com
