It seems I made a mess with the latest win32 beta release (again). Over 2800 downloads and you were the first to notice, so thanks for the feedback. I wonder how many of the others failed and never mentioned anything? Some of the dlls we shipped with that pypy depend on the Visual 10 runtime, and some on the Visual 2008. Specifically, openssl (libeay32.dll and ssleay32.dll) are linked with Visual 10 where everything else is linked with Visual 2008. I repackaged a zip to http://picus.org.il/… [View More]

PyPy Team: Could you figure out how to make PyPy support Pygame (www.pygame.org)? I am trying, but having no luck so far. Signed, Thomas

Await-keyword
by Jonathan Slenders Dec. 21, 2012

Dec. 21, 2012

Dear all, For my work, I needed a python sandbox which contained the 'await' keyword for asynchronous programming, just like c# does. I found it very easy to extend the 2.7 grammar and include this keyword. https://bitbucket.org/jonathanslenders/pypy Personally, I think this is a very clean solution for Twisted's @defer.inlineCalbacks, Tornado's @gen.engine, and similar functions in other async frameworks. Just sharing this information, but I'd also like to know whether Python code … [View More]

Twisted sandbox library.
by Jonathan Slenders Dec. 21, 2012

Dec. 21, 2012

Hi all, me again :) As contributions for a better sandbox hypervisor library were welcome, I here contribute our Twisted Matrix hypervisor. https://github.com/jonathanslenders/twisted-sandlib/blob/master/sandlib.py If there is interest for adding this to Pypy's repository, surely I can add some more documentation, tests and sample code. Cheers, Jonathan

pypy compatibility page
by Wiktor Mizdal Dec. 20, 2012

Dec. 20, 2012

I try use in Pypy 2 codes from Compatibility Page: 1) open("filename", "w").write("stuff") 2) with open("filename", "w") as f: f.write("stuff") and it works. Is Compatibility Page actual? Wiktor

PyPy Team, I tried to use PyPy on Win64. It crashed because I needed a file called 'MSCVR100.DLL'. Could you distribute that with PyPy? Signed, Thomas

Scrapy fails in PyPy
by Joe Hillenbrand Dec. 17, 2012

Dec. 17, 2012

Now that lxml works in PyPy, I've been excited to try Scrapy in PyPy 2.0 I've run into this issue. I'm not sure what could be happening here, but I suspect it could be a twisted+pypy issue. I'm hoping it might look familiar to someone. ERROR: Error caught on signal handler: <bound method LogStats.spider_opened of <scrapy.contrib.logstats.LogStats object at 0x0000000006f3a8e0>> Traceback (most recent call last): File "/usr/local/pypy/site-packages/twisted/internet/defer.… [View More]py", line 1045, in _inlineCallbacks result = g.send(result) File "/usr/local/pypy/site-packages/scrapy/core/engine.py", line 225, in open_spider yield self.signals.send_catch_log_deferred(signals.spider_opened, spider=spider) File "/usr/local/pypy/site-packages/scrapy/signalmanager.py", line 23, in send_catch_log_deferred return signal.send_catch_log_deferred(*a, **kw) File "/usr/local/pypy/site-packages/scrapy/utils/signal.py", line 53, in send_catch_log_deferred *arguments, **named) --- <exception caught here> --- File "/usr/local/pypy/site-packages/twisted/internet/defer.py", line 134, in maybeDeferred result = f(*args, **kw) File "/usr/local/pypy/site-packages/scrapy/xlib/pydispatch/robustapply.py", line 47, in robustApply return receiver(*arguments, **named) exceptions.TypeError: spider_opened() got 2 unexpected keyword arguments ERROR: Error caught on signal handler: <bound method LogStats.response_received of <scrapy.contrib.logstats.LogStats object at 0x0000000006f3a8e0>> Traceback (most recent call last): File "/usr/local/pypy/site-packages/twisted/internet/defer.py", line 464, in _startRunCallbacks self._runCallbacks() File "/usr/local/pypy/site-packages/twisted/internet/defer.py", line 551, in _runCallbacks current.result = callback(current.result, *args, **kw) File "/usr/local/pypy/site-packages/scrapy/core/engine.py", line 200, in _on_success response=response, request=request, spider=spider) File "/usr/local/pypy/site-packages/scrapy/signalmanager.py", line 19, in send_catch_log return signal.send_catch_log(*a, **kw) --- <exception caught here> --- File "/usr/local/pypy/site-packages/scrapy/utils/signal.py", line 22, in send_catch_log *arguments, **named) File "/usr/local/pypy/site-packages/scrapy/xlib/pydispatch/robustapply.py", line 47, in robustApply return receiver(*arguments, **named) exceptions.TypeError: response_received() got 4 unexpected keyword arguments ERROR: Error caught on signal handler: <bound method CoreStats.response_received of <scrapy.contrib.corestats.CoreStats object at 0x00000000061b8d08>> Traceback (most recent call last): File "/usr/local/pypy/site-packages/twisted/internet/defer.py", line 464, in _startRunCallbacks self._runCallbacks() File "/usr/local/pypy/site-packages/twisted/internet/defer.py", line 551, in _runCallbacks current.result = callback(current.result, *args, **kw) File "/usr/local/pypy/site-packages/scrapy/core/engine.py", line 200, in _on_success response=response, request=request, spider=spider) File "/usr/local/pypy/site-packages/scrapy/signalmanager.py", line 19, in send_catch_log return signal.send_catch_log(*a, **kw) --- <exception caught here> --- File "/usr/local/pypy/site-packages/scrapy/utils/signal.py", line 22, in send_catch_log *arguments, **named) File "/usr/local/pypy/site-packages/scrapy/xlib/pydispatch/robustapply.py", line 47, in robustApply return receiver(*arguments, **named) exceptions.TypeError: response_received() got 4 unexpected keyword arguments Here are the definitions for CoreStats and LogStats: https://github.com/scrapy/scrapy/blob/0.16/scrapy/contrib/logstats.py https://github.com/scrapy/scrapy/blob/0.16/scrapy/contrib/corestats.py Let me know if this is a PyPy bug and I will turn it into a bug report.

SegFault when running Scrapy tests.
by Joe Hillenbrand Dec. 14, 2012

Dec. 14, 2012

Hi all, I'm starting a new thread because the last one seems to be on a new topic. I was just trying out the scrapy unit tests in PyPy and I've run into some segfaults. To reproduce, download and install Scrapy: https://github.com/scrapy/scrapy Then run this in the tests directory: /usr/local/pypy/bin/trial test_http_request.py I haven't found the exact source of the issue yet, but I'm posting this in case somebody can find it faster. Thanks, -Joe

Raymond's proposed new dict layout
by Carl Friedrich Bolz Dec. 12, 2012

Dec. 12, 2012

Hi all, I've been wondering whether the recipe that Raymond Hettinger posted would also solve PyPy's performance problems with making huge dictionaries: http://code.activestate.com/recipes/578375/ The proposed layout makes the pointer-storing part of the dictionary behave much more like a list. In particular, the write pattern is much more regular, so the card-marking techniques we use for lists should be applicable. Any thoughts? Cheers, Carl Friedrich

FOSS for scientists devroom at FOSDEM 2013
by Sylwester Arabas Dec. 10, 2012

Dec. 10, 2012

Dear PyPy Team, A day-long session ("devroom") on Free/Libre and Open Source Software (FLOSS) for scientists will be held during the next FOSDEM conference, Brussels, 2-3 February 2013 (http://fosdem.org/2013). We aim at having a dozen or two short talks introducing projects, advertising brand new features of established tools, discussing issues relevant to the development of software for scientific computing, and touching on the interdependence of FLOSS and open science. You can find … [View More]
