Who are the decimal volunteers? Re: [Python-checkins] cpython: Resize the coefficient to MPD_MINALLOC also if the requested size is below
by Jim Jewett April 9, 2012

April 9, 2012

I remember that one of the concerns with cdecimal was whether it could be maintained by anyone except Stefan (and a few people who were already overcommitted). If anyone (including absolute newbies) wants to step up, now would be a good time to get involved. A few starter questions, whose answer it would be good to document: Why is there any need for MPD_MINALLOC at all for (immutable) numbers? I suspect that will involve fleshing out some of the memory management issues around dynamic … [View More]decimals, as touched on here: http://www.bytereef.org/mpdecimal/doc/libmpdec/memory.html#static-and-dynam… On Mon, Apr 9, 2012 at 3:33 PM, stefan.krah <python-checkins(a)python.org> wrote: > http://hg.python.org/cpython/rev/170bdc5c798b > changeset: 76197:170bdc5c798b > parent: 76184:02ecb8261cd8 > user: Stefan Krah <skrah(a)bytereef.org> > date: Mon Apr 09 20:47:57 2012 +0200 > summary: > Resize the coefficient to MPD_MINALLOC also if the requested size is below > MPD_MINALLOC.

Removing surplus fields from the frame object and not adding any new ones.
by Mark Shannon April 9, 2012

April 9, 2012

The frame object is a key object in CPython. It holds the state of a function invocation. Frame objects are allocated, initialised and deallocated at a rapid rate. Each extra field in the frame object requires extra work for each and every function invocation. Fewer fields in the frame object means less overhead for function calls, and cleaner simpler code. We have recently removed the f_yieldfrom field from the frame object. (http://bugs.python.org/issue14230) The f_exc_type, f->… [View More]

Pep 393 and debugging
by Kristján Valur Jónsson April 7, 2012

April 7, 2012

I just had my first fun with Pep 393 strings and debuggers. Trying to debug a deadlocked python program, I'm trying to figure out the callstack of the thread in the debugger. I ended up with something like: (char*)&((PyASCIIObject*)(tstate->frame->f_code->co_filename))[1] while previously, it was sufficient to do (PyUnicodeObject*)(tstate->frame->f_code->co_filename) Obviously this won't work for non-ASCII objects. I wonder if there is a way to make this … [View More]
