PyPy3 2.4.0 released
by Philip Jenvey 21 Oct '14

21 Oct '14

================================================= PyPy3 2.4 - Snow White ================================================= We're pleased to announce PyPy3 2.4, which contains significant performance enhancements and bug fixes. You can download the PyPy3 2.4.0 release here: http://pypy.org/download.html PyPy3 Highlights ================ Issues reported with our previous release were fixed after reports from users on our new issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at #pypy. Here is a summary of the user-facing PyPy3 specific changes: * Better Windows compatibility, e.g. the nt module functions _getfinalpathname & _getfileinformation are now supported (the former is required for the popular pathlib library for example) * Various fsencode PEP 383 related fixes to the posix module (readlink, uname, ttyname and ctermid) and improved locale handling * Switched default binary name os POSIX distributions to 'pypy3' (which symlinks to to 'pypy3.2') * Fixed a couple different crashes related to parsing Python 3 source code Further Highlights (shared w/ PyPy2) ==================================== Benchmarks improved after internal enhancements in string and bytearray handling, and a major rewrite of the GIL handling. This means that external calls are now a lot faster, especially the CFFI ones. It also means better performance in a lot of corner cases with handling strings or bytearrays. The main bugfix is handling of many socket objects in your program which in the long run used to "leak" memory. We fixed a memory leak in IO in the sandbox_ code We welcomed more than 12 new contributors, and conducted two Google Summer of Code projects, as well as other student projects not directly related to Summer of Code. * Reduced internal copying of bytearray operations * Tweak the internal structure of StringBuilder to speed up large string handling, which becomes advantageous on large programs at the cost of slightly slower small *benchmark* type programs. * Boost performance of thread-local variables in both unjitted and jitted code, this mostly affects errno handling on linux, which makes external calls faster. * Move to a mixed polling and mutex GIL model that make mutlithreaded jitted code run *much* faster * Optimize errno handling in linux (x86 and x86-64 only) * Remove ctypes pythonapi and ctypes.PyDLL, which never worked on PyPy * Classes in the ast module are now distinct from structures used by the compiler, which simplifies and speeds up translation of our source code to the PyPy binary interpreter * Win32 now links statically to zlib, expat, bzip, and openssl-1.0.1i. No more missing DLLs * Many issues were resolved_ since the 2.3.1 release in June .. _`whats-new`: http://doc.pypy.org/en/latest/whatsnew-2.4.0.html .. _resolved: https://bitbucket.org/pypy/pypy/issues?status=resolved .. _sandbox: http://doc.pypy.org/en/latest/sandbox.html We have further improvements on the way: rpython file handling, numpy linalg compatibility, as well as improved GC and many smaller improvements. Please try it out and let us know what you think. We especially welcome success stories, we know you are using PyPy, please tell us about it! Cheers The PyPy Team

Semi-official read-only Github mirror of the CPython Mercurial repository
by Eli Bendersky 15 Oct '14

15 Oct '14

Hi all, https://github.com/python/cpython is now live as a semi-official, *read only* Github mirror of the CPython Mercurial repository. Let me know if you have any problems/concerns. I still haven't decided how often to update it (considering either just N times a day, or maybe use a Hg hook for batching). Suggestions are welcome. The methodology I used to create it is via hg-fast-export. I also tried to pack and gc the git repo as much as possible before the initial Github push - it went down from almost ~2GB to ~200MB (so this is the size of a fresh clone right now). Eli P.S. thanks Jesse for the keys to https://github.com/python

Review tool not detecting all changed files
by Saimadhav Heblikar 15 Oct '14

15 Oct '14

Hi, We were working on IDLE related issue [1] , when I noticed that the review tool does not detect all affected files for the cfg-ext-34-2.diff patch uploaded by Terry Reedy. Version 1 of the same patch does not have this issue - the only difference between the two files being line endings and time stamps. Also see Terry Reedy's message in the same issue. [3] Could someone please let me know if this is normal behavior or not? [1] - http://bugs.python.org/issue3068 [2] - http://bugs.python.org/file36904/cfg-ext-34-2.diff [3] - http://bugs.python.org/issue3068#msg229315 -- Regards Saimadhav Heblikar

Disabling SSL 3.0
by Donald Stufft 14 Oct '14

14 Oct '14

A big security breach of SSL 3.0 just dropped a little while ago (named POODLE). With this there is now no ability to securely connect via SSL 3.0. I believe that we should disable SSL 3.0 in Python similarly to how SSL 2.0 is disabled, where it is disabled by default unless the user has explicitly re-enabled it. The new attack essentially allows reading the sensitive data from within a SSL 3.0 connection stream. It takes roughly 256 requests to break a single byte so the attack is very practical. You can read more about the attack here at the google announcement [1] or the whitepaper [2].

Running for longer keeps this going. I think the figures are being generated, cleared in the notebook, but still existing somehow in the background. Is there a way to determine if this is happening? Is there a proper way to write the animation to avoid this? thanks! Brian Blais ----------------- bblais(a)gmail.com http://web.bryant.edu/~bblais

Status of C compilers for Python on Windows
by Victor Stinner 12 Oct '14

12 Oct '14

Hi, Windows is not the primary target of Python developers, probably because most of them work on Linux. Official Python binaries are currently built by Microsoft Visual Studio. Even if Python developers get free licenses thanks for Microsoft, I would prefer to use an open source compiler if it would be possible. So *anyone* can build Python from scatch. I don't like the requirement of having a license to build Python. The free version (Visual Studio Express) only supports 32-bit and doesn't support PGO build (Profile-Guided Optimizations, which are disabled if I remember correctly because of compiler bugs). I know that it's hard to replace Visual Studio. I don't want to do it right now, but I would like to discuss that with you. === Open Watcom Jeffrey Armstrong is working on the Python support of OpenWatcom(v2), see: http://lightningpython.org/ https://bitbucket.org/ArmstrongJ/lightning-python This compiler was initially written on MS-DOS in 32-bit, but it now supports Windows and Linux as well. The 64-bit mode is new and experimental. The Open Watcom "v2" project is actively developed at: https://github.com/open-watcom/open-watcom-v2/ On Linux, Open Watcom don't support dynamic linking. On Windows, it uses its own C library. I'm not sure that Open Watcom is the best choice to build Python on Windows. === MinGW Some people tried to compile Python. See for example: https://bitbucket.org/puqing/python-mingw We even got some patches: http://bugs.python.org/issue3871 (rejected) See also: https://stackoverflow.com/questions/15365249/build-python-with-mingw-and-gcc MinGW reuses the Microsoft C library and it is based on GCC which is very stable, actively developed, supports a lot of archiectures, etc. I guess that it should be possible to reuse third party GCC tools like the famous GDB debugger? === Cywin Cygwin was written compile POSIX applications on Windows and it provides a DLL for that. Python doesn't need that, it uses directly the Windows native API. I don't think that we should use Cygwin. === Clang I have no idea of the support of Clang on Windows. Which C library is used? I found some pages: http://clang.llvm.org/docs/MSVCCompatibility.html http://blog.llvm.org/2014/07/clangllvm-on-windows-update.html This article starts with "It’s time for an update on Clang’s support for building native Windows programs, compatible with Visual C++!". Good. I see binaries for Windows. === Other compilers? Do you know other C compiler which can be used to build Python? === Requirements A compiler alone is not enough. To develop, we need tools to automate the compilation, we need a good debugger, and other similar tools. (Personally, I don't need an IDE. I mostly write code on Linux and only run Windows to ensure that my code works on Windows before pushing it.) IMO 64-bit support is simply required (we currently provide 64-bit binaries on Windows). Supporting ARM can be interesting for Windows 8 and Windows 9. Some parts of Python are low-level like ctypes with libffi. The _decimal module uses libmpdec which is highly optimized. In short, the goal is to have a full working standard Python library. It's probably better to reuse the Microsoft C library instead of having to embed a different C library. What do you think? What about the Python stable ABI? Would it be broken if we use a different compiler? What about third party Python extensions? What about external dependencies like gzip, bz2, Tk, Tcl, OpenSSL, etc.?
