Re: [Python-Dev] Decoding libpython frame information on the stack
Hi Mithun, Because python-dev is a mailing list for the development *of* Python rather than development *with* Python, I believe you may not have posted to the best list. Further information about this distinction, and some discussion about potentially setting up a special-interest list exclusively for Python/C interactions, can be found in this recent thread: http://mail.python.org/pipermail/python-dev/2007-June/073680.html Regarding your question, I'll try to answer it as best I can: on our Windows application, we use Microsoft minidumps [1] instead of core dumps. At the time that a crash occurs and a minidump is written, we have some code that digs into the Python interpreter state to get a text traceback for every Python thread currently in execution at the time of the crash, which is appended to the log file that is sent with the minidump in the automated bug report. Doing this is a bit risky because it assumes that the relevant parts of the Python interpreter state aren't corrupt at the time of the crash, but precautions can be made to deal with this edge case. So while I can't help you get a bead on debugging core files, you may want to consider a similar solution on the Unix platform. - Atul [1] http://msdn2.microsoft.com/en-us/library/ms680369.aspx On 6/28/07, Mithun R N <[EMAIL PROTECTED]> wrote: > Hi All, > > Am a new subscriber to this list. > Am facing an issue in deciphering core-files of > applications with mixed C and libpython frames in it. > > I was thinking of knowing any work that has been done > with respect to getting into the actual python line > (file-name.py:) from the libpython frames > on the stack while debugging such core-files.

Re: [Python-Dev] Known doctest bug with unicode?
Can you provide an example that fails? This seems to work on my end, for
instance:
>>> mydict = { u'\u2026' : 'ellipsis' }
>>> mydict[u'\u2026']
'ellipsis'

Re: [Python-Dev] Do we still need BaseAddress in .vcproj files?
A while back I was reading an MSDN article that did some concrete research on the performance benefits of rebasing DLLs to avoid fixups at runtime, and it actually concluded that on modern systems, the benefits are really negligible. I tried finding the article on the net just now, though, and I couldn't, so don't take my word for it. This 1995 MSDN article provides an explanation and some raw numbers for systems at that time, though: http://msdn2.microsoft.com/en-us/library/ms810432.aspx - Atul On Fri, Apr 25, 2008 at 2:00 PM, "Martin v.
