pickle output not unique
by Kristján Valur Jónsson Aug. 4, 2010

Aug. 4, 2010

Hi there. I was made aware of this oddity here: import cPickle reffed = "xKITTENSx"[1:-1] print repr(cPickle.dumps(reffed)) print repr(cPickle.dumps("xKITTENSx"[1:-1])) These strings are different, presumably because of the (ob_refcnt == 1) optimization used during object pickling. This might come as a suprise to many, and is potentially dangerous if pickling is being used as precursor to some hashing function. For example, we use code that caches function calls, using something akin to: … [View More]

Hi Giampaolo, Now that we're in quasi-freeze for 2.6.6 final, this is the kind of change I'd like to review before backporting. In this case, I'll let it through, but please check with me first next time. And thanks for your work! -Barry On Aug 04, 2010, at 10:58 AM, giampaolo.rodola wrote: >Author: giampaolo.rodola >Date: Wed Aug 4 10:58:38 2010 >New Revision: 83704 > >Log: >Merged revisions 83703 via svnmerge from >svn+ssh://pythondev@svn.python.org/python/branches/… [View More]release27-maint > >........ > r83703 | giampaolo.rodola | 2010-08-04 10:35:25 +0200 (mer, 04 ago > 2010) | 1 line > fix issue #2944: asyncore doesn't handle connection refused > correctly (patch by Alexander Shigin) >........ > > >Modified: > python/branches/release26-maint/ (props changed) > python/branches/release26-maint/Lib/asyncore.py > python/branches/release26-maint/Misc/ACKS > python/branches/release26-maint/Misc/NEWS > >Modified: python/branches/release26-maint/Lib/asyncore.py >============================================================================== >--- python/branches/release26-maint/Lib/asyncore.py (original) >+++ python/branches/release26-maint/Lib/asyncore.py Wed Aug 4 >10:58:38 2010 @@ -422,8 +422,11 @@ > self.handle_read() > > def handle_connect_event(self): >- self.connected = True >+ err = self.socket.getsockopt(socket.SOL_SOCKET, >socket.SO_ERROR) >+ if err != 0: >+ raise socket.error(err, _strerror(err)) > self.handle_connect() >+ self.connected = True > > def handle_write_event(self): > if self.accepting: > >Modified: python/branches/release26-maint/Misc/ACKS >============================================================================== >--- python/branches/release26-maint/Misc/ACKS (original) >+++ python/branches/release26-maint/Misc/ACKS Wed Aug 4 >10:58:38 2010 @@ -817,3 +817,4 @@ > Peter Åstrand > Jesse Noller > Fredrik Håård >+Alexander Shigin > >Modified: python/branches/release26-maint/Misc/NEWS >============================================================================== >--- python/branches/release26-maint/Misc/NEWS (original) >+++ python/branches/release26-maint/Misc/NEWS Wed Aug 4 >10:58:38 2010 @@ -89,6 +89,8 @@ > Library > ------- > >+- Issue #2944: asyncore doesn't handle connection refused correctly. >+ > - Issue #8447: Make distutils.sysconfig follow symlinks in the path to > the interpreter executable.

Windows MSI installer with minimal options
by Paul Kippes Aug. 4, 2010

Aug. 4, 2010

Martin, For the most part, the information at http://www.python.org/download/releases/2.4/msi/ assisted me with automating a 2.7 installation on Windows XP. The following initial attempt, however, failed to provide a working python installation. (Messages are either "The system cannot execute the specified program." or "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.") msiexec /qb /i python-2.7.msi … [View More]

Status of Lib/_threading_local.py ?
by Antoine Pitrou Aug. 4, 2010

Aug. 4, 2010

Hello, While Lib/_threading_local.py is meant as a fallback Python implementation of thread-local objects, it looks like it will never be invoked in practice. The reason is that the thread-local code in Modules/_threadmodule.c in unconditionally compiled. Furthermore, _threading_local.py imports threading which itself imports _thread, so it's not possible for _threading_local to function if for some reason _thread fails to build or import. What should we do with _threading_local? Keep it as … [View More]

co_firstlineno on decorated functions

Aug. 3, 2010

[Since I received no replies on this in python-list, perhaps python-dev is more appropriate] Hello, I've been tinkering with __code__.co_firstlineno for testing the trace.py module (Python Issue 9315), and ran into an interesting problem. Consider this code: def dummydecorator(f): return f def foo(a): return a @dummydecorator def bar(a): return a if __name__ == "__main__": print foo.__code__.co_firstlineno print bar.__code__.co_firstlineno ---- The first print out … [View More]

breaking an exception chain
by R. David Murray Aug. 3, 2010

Aug. 3, 2010

Working with Catherine on an argparse bug, we ran into a test that was apparently failing by raising a SystemExit, when the test harness was supposed to be catching that error. It took us a bit to realize that there wasn't really a SystemExit error, but that what we were seeing was the SystemExit chained to the exception the test harness was purposfully raising after catching the SystemExit. In Python2, only the second, intentionally raised exception would be printed by unittest. In Python3, … [View More]
