Hi, Slightly off-topic (as it's not directly about using or developing LLVM): http://code.google.com/p/unladen-swallow/wiki/ProjectPlan "Our long-term proposal is to replace CPython's custom virtual machine with a JIT built on top of LLVM, while leaving the rest of the Python runtime relatively intact." Just curious, has anyone here heard more about this project? Regards, Paul P.S. If I'd heard about this just 6 days later (e.g. Aprils Fools) I wouldn't hav...

...is flexible and easy to experiment with and retarget to different platforms (also non-C ones) and such that high performance can be achieved through high-level implementations of dynamic optimisation techniques. The interpreter and object model implementations shipped with 0.6 can be run on top of CPython and implement the core language features of Python as of CPython 2.3. PyPy passes around 90% of the Python language regression tests that do not depend deeply on C-extensions. Some of that functionality is still made available by PyPy piggy-backing on the host CPython interpreter. Double interpr...

Knorrie and I just discussed our plans for sid and buster, on the phone. Here's my notes of the discussion. Plan is to upload Knorrie's 4.11 packages to experimental, to make them more public, while we fix the bugs in them. There's a list of Salsa issues and the BTS bugs list. This duplication is not ideal. We agreed that new things should go to the BTS. For now we'll keep

Since December 2014, clients using the Python poplib library (getmail in my case) started to limit the line length of RETR and other command responses sent from the server to 2048 bytes: See https://bugs.python.org/issue16041 (Included at least in Python-2.7.9) Dovecot doesn't have line split in the POP3 module, so Python fails to retrieve messages with long lines. RFC 1939 says: "

In Unladen Swallow we (intend to) compile each function as we determine it's hot. To "compile" a function means to translate it from CPython bytecode to LLVM IR, optimize the IR using a FunctionPassManager, and JIT the IR to machine code. We'd like to include inlining among our optimizations. Currently the Inliner is a CallGraphSCCPass, which can only be run by the (Module)PassManager and which will try to inline calls into every fu...

...reak the lines without breaking the message? Please note that if you are right, I should post a bug on the Python project. You can see in this "traceforward" that Python's poplib will throw an error_proto exception if RETR returns lines longer than 2048 bytes: https://hg.python.org/cpython/file/0db36098b908/Lib/poplib.py#l227 https://hg.python.org/cpython/file/0db36098b908/Lib/poplib.py#l165 https://hg.python.org/cpython/file/0db36098b908/Lib/poplib.py#l142 https://hg.python.org/cpython/file/0db36098b908/Lib/poplib.py#l370 def _getline(self): line = ""...

Apparently there is a php 7.4 configuration missing.? This is bindings 1.4.17 running on a Mint 20 system. I see this in the config output: cpython-38.opt-1.pyc checking for php-config7.3... no checking for php-config7.2... no checking for php-config7.1... no checking for php-config7.0... no checking for php-config... no It didn't look for 7.4. Thanks, Jim.

...to get it translated with the rest of PyPy. This makes using the translated pypy interactively much more pleasant, as compilation is considerably faster than in 0.7.0. - Some Speed enhancements. Translated PyPy is now about 10 times faster than 0.7 but still 10-20 times slower than CPython on pystones and other benchmarks. At the same time, language compliancy has been slightly increased compared to 0.7 which had already reached major CPython compliancy goals. - Some experimental features are now translateable. Since 0.6.0, PyPy shipped with an experimental Object Space (...

I am currently writing a lazy functional language and visualizing its execution to explain laziness for my undergraduate dissertation. I have also played with some industry-level interpreters in the past namely V8 and CPython.

Hi, I've been trying to get the python bridge (rpy2) to build for 64-bit R and python. The current stumbling block is that mingw can't use the python27.lib file that comes with CPython and so I need to generate libpython27.a. When I use dlltool from rtools to do that however, I end up with a 32-bit file: >"G:\Rtools\gcc-4.6.3\i686-w64-mingw32\bin\dlltool" -e libpython27.a -d python27.def python27.dll >objdump -f libpython27.a libpython27.a: file format pe-i...
