Problem building C Extension
by Kevin Gill Dec. 14, 2010

Dec. 14, 2010

Hi, I am new to PyPy. I built pypy using... $ python translate.py --opt=jit targetpypystandalone.py When I try to build eggs with C extensions it doesn't work. I am using pip in a virtualenv. The build uses the wrong compiler "cc" instead of "gcc" and does not use CFLAGS. For example: $ pip -v install zope.interface==3.6.1 shows this output cc -I/home/kevin/pypp/env/include -c src/zope/interface/_zope_interface_coptimizations.c -o build/temp.linux-x86_64-2.5/src/zope/interface/… [View More]

Migration to mercurial
by Antonio Cuni Dec. 14, 2010

Dec. 14, 2010

Hi all, finally, it's happening :-). Thanks to Ronny's work, we are going to complete the migration to mercurial very soon. The pypy buildbot is already configured to pull from the bitbucket repository: http://bitbucket.org/pypy/pypy I have tried to run a test build, and it seems to work ok. We will see tomorrow morning how the nightly runs went. If everything goes right, tomorrow we will declare the hg repo as the "official" one: the svn repo will be made read-only (as soon as armin does … [View More]

BTW, what's going on with the deprecation of sys.setrecursionlimit? What should I use instead? /home/dstromberg/src/home-svn/backshift/trunk/treap.py:40: DeprecationWarning: setrecursionlimit deprecated sys.setrecursionlimit(min_heap_size)

gdbm and dbm merge - ctypes bug?
by Dan Stromberg Dec. 11, 2010

Dec. 11, 2010

I'm finding that my gdbm module (based on ctypes) is infrequently (but it might be consistent) giving gibberish when run on pypy 1.4, but not when run on cpython 2.6 or cpython 3.1. More specifically, sometimes the keys come up looking like undefined memory. The values associated with those keys always seem OK. I believe I am comparing apples to apples - I'm using gdbm_ctypes with the cpython's too, even though they come with a module for some doing the same thing - for the sake of … [View More]

os.major? os.minor?
by Dan Stromberg Dec. 11, 2010

Dec. 11, 2010

What would be the best way to add os.major and os.minor to the os module? They appear to be C macros on some systems, so I'm guessing most FFI's aren't going to see them without a wrapper. On Linux, there's a C function that a macro is #ifdef'd to, but that seems less than amazingly portable.

Leysin Winter sprint: Jan 16-22
by Armin Rigo Dec. 10, 2010

Dec. 10, 2010

===================================================================== PyPy Leysin Winter Sprint (16-22nd January 2011) ===================================================================== As announced on http://morepypy.blogspot.com/2010/12/leysin-winter-sprint.html, the next PyPy sprint will be in Leysin, Switzerland, for the seventh time. This is a fully public sprint: newcomers and topics other than those proposed below are welcome. ------------------------------ Goals and … [View More]topics of the sprint ------------------------------ * Now that we have released 1.4, and plan to release 1.4.1 soon (possibly before the sprint), the sprint itself is going to be mainly working on fixing issues reported by various users. Of course this does not prevent people from showing up with a more precise interest in mind. If there are newcomers, we will gladly give introduction talks. * We will also work on polishing and merging the long-standing branches that are around, which could eventually lead to the next PyPy release. These branches are notably: - fast-forward (Python 2.7 support, by Benjamin, Amaury, and others) - jit-unroll-loops (improve JITting of smaller loops, by Hakan) - arm-backend (a JIT backend for ARM, by David) - jitypes2 (fast ctypes calls with the JIT, by Antonio). * And as usual, the main side goal is to have fun in winter sports :-) We can take a day off for ski. ----------- Exact times ----------- The work days should be 16-22 January 2011. People may arrive on the 15th already and/or leave on the 23rd. ----------------------- Location & Accomodation ----------------------- Leysin, Switzerland, "same place as before". Let me refresh your memory: both the sprint venue and the lodging will be in a very spacious pair of chalets built specifically for bed & breakfast: http://www.ermina.ch/. The place has a good ADSL Internet connexion with wireless installed. You can of course arrange your own lodging anywhere (as long as you are in Leysin, you cannot be more than a 15 minutes walk away from the sprint venue), but I definitely recommend lodging there too -- you won't find a better view anywhere else (though you probably won't get much worse ones easily, either :-) Please *confirm* that you are coming so that we can adjust the reservations as appropriate. The rate so far has been around 60 CHF a night all included in 2-person rooms, with breakfast. There are larger rooms too (less expensive) and maybe the possibility to get a single room if you really want to. Please register by svn: http://codespeak.net/svn/pypy/extradoc/sprintinfo/leysin-winter-2011/people… or on the pypy-sprint mailing list if you do not yet have check-in rights: http://codespeak.net/mailman/listinfo/pypy-sprint You need a Swiss-to-(insert country here) power adapter. There will be some Swiss-to-EU adapters around -- bring a EU-format power strip if you have one. ===================================================================== Armin Rigo [View Less]
