The most common practice is to pass some kind of debugging info to the constructor, otherwise, setting debug info on the instance is ok, too. my_object = SomeClass() my_object.debug_info = 'This is the typical case' You can also use the inspect module to grab the source line of the caller: http://codepad.org/YvStcEMv -- William Leslie Notice: Likely much of this email is, by the nature of copyright, covered under copyright law.

Getting involved
by John Smith 12 Jul '14

As a less objectionable alternative, what about a package which when passed code (string/code object/not sure) returns a newly compiled object with tail call optimization? J

Unable to build pypy with '--shared' option
by Yichao Yu 05 Jul '14

05 Jul '14

Hi, I have got the following error (see below, with a lot of other compiler warnings) when trying to compile pypy with the '--shared' option during the last stop (compile_c). I've seen similar issues without --shared before and it was solved by setting the CFLAGS to -O1 but that doesn't seem to help this time. Is it possible to fix this?

compiling with 4G ram
by Benedek Zoltan 05 Jul '14

05 Jul '14

Hi, Recently I tried to compile Pypy on a Linux x86_64 machine with only 4G RAM, according to the instructions: http://pypy.org/download.html I tried by CPython2.6 by the command: PYPY_GC_MAX_DELTA=200MB python2.6 --jit loop_longevity=300 ../../rpython/bin/rpython -Ojit targetpypystandalone I had to remove the --jit option and the compiling process uses all the ram. Is there a way to reduce the used memory amount, or I have no chance to try Pypy on this machine? Thanks Zoltan

How to get transparent proxy working.
by Yichao Yu 04 Jul '14

04 Jul '14

Hi, I found the transparent proxy in pypy recently. However, the example from the document doesn't seem to work here[1]. Many other builtin types (including tuple, dict, int) and the types that inherit from them does not work either. `object`, however, can be wrapped but doesn't seem to behave correctly either. (add doesn't work) I am using the latest version (as of a few hours ago at least) from bitbucket (28a1ebabc3e4) and I have recompiled it with --objspace-std-withtproxy just to make sure it is enabled. Is it broken or am I missing anything? Yichao Yu [1] http://nbviewer.ipython.org/gist/yuyichao/6e4ca22b9aa52bd02661

Hi, I'm wondering if there will be pypy sprints at Europython this year (?) And if so, which are the principal topics (I assume stm is one of them..)? Thanks, Martin
