otrace - an object-oriented debugger for nonlinear tracing
by Ramalingam Saravanan 11 Jun '12

11 Jun '12

otrace is an object-oriented debugger for nonlinear tracing of asynchronous or multithreaded interactive programs. It addresses some of the limitations of sequential debugging techniques which do not work well with server programs, where multiple requests are handled in parallel. For example, instrumenting web servers with print/logging statements can often result in voluminous log output with interleaved streams of messages. otrace takes a different approach to debugging that relies less on sequential operations. Its features including taking "snapshots" of variables for tracing, "tagging" objects for tracking across different method invocations, and modifying live code ("monkey patching") to insert print statements etc. otrace maps all the objects in the running program, as well as the "snapshot" objects, to a virtual filesystem mounted under "/osh". It provides a shell-like interface, oshell, with commands like "cd", "ls" etc. that can be used to browse classes, methods, and instance variables in the virtual filesystem. Tab completion and simple wildcarding are supported. This is the first public release of otrace. It can be installed from: http://pypi.python.org/pypi/otrace - Project page: http://info.mindmeldr.com/code/otrace - Source: http://github.com/mitotic/otrace - License: BSD - Version: 0.30 Enjoy, R. Saravanan ------------------ PS. Here is a brief excerpt of terminal output from a demo session, to provide a flavor of oshell command usage: # Initiate tracing of a method globals> cd Receive osh..Receive> pwd /osh/globals/Receive osh..Receive> ls -lf resp* respond = <unbound method Receive.respond> osh..Receive> trace respond Tracing Receive.respond

PyDoc - Python Documentation Plugin for Eclipse
by Alexey Gaidamaka 10 Jun '12

10 Jun '12

Greets! Since i'm new to Python, i've decided to create a handy plugin for Elipse SDK which is my primary dev environment. Practically the plugin is a simple html archive from python documentation website running inside Eclipse so you can call it using Eclipse help system. As for now it is pretty large (~7 mb), but i'm planning to optimize it in near future. For more information, please visit: http://pydoc.tk/ or https://sourceforge.net/projects/pydoc/ ------------------------------------------------------------------------ Advices are appreciated!

[ANN] tperimeter 1.113 Released And Available
by Tim Daneliuk 10 Jun '12

10 Jun '12

'tperimeter' Version 1.113 is released and available at: http://www.tundraware.com/Software/tperimeter/ The last public release was 1.112 What's New ---------- Changed the wrapper file rebuild logic to delete outstanding access requests independently of how often the script is run (either by cron, or manually). This means that the 'cron' frequency now determines the average waiting time before a user's request is fulfilled. The '${DURATION}' variable in 'rebuild-hosts.allow.sh' sets how long access will be permitted (The default value is 10 minutes). Minor documentation updates, typo fixes, and housekeeping. What Is 'tperimeter'? --------------------- Have you ever been away from the office and needed, say, ssh access to your system? Ooops - you can't do that because in your zealous pursuit of security, you set your TCP wrappers to prevent outside access to all but a select group of hosts. Worse still, everywhere you go, your local IP address changes so there is no practical way to open up the wrappers for this situation. 'tperimeter' is a dynamic TCP wrapper control system that gives you (limited) remote control of your TCP wrapper configuration. It does this via a web interface that you've (hopefully) secured with https/SSL. You just log in, specify your current IP address and one of the services you want to access. 'tperimeter' will then briefly open a hole in your wrappers long enough to let you in. It then automatically closes the hole again. Voila! Remote access to your system, wherever you are. You get much of the facility of a VPN or so-called "port knocking" without most of the aggravation. As a side benefit, 'tperimeter' will also simplify management of your standard /etc/hosts.allow TCP wrapper control file. 'tperimeter' is written in python, shell script, and html. It is very small and easy to maintain. It was developed and tested on FreeBSD 4.x/8.x, and apache 1.x/2.x, but should run with very minor (or no) modification on most Unix-like systems like Linux or Mac OS X hosts. It comes complete with documentation in html, pdf, dvi, and Postscript formats. There is no licensing fee for any use, personal, commercial, government, or institutional. -- ---------------------------------------------------------------------------- Tim Daneliuk tundra(a)tundraware.com PGP Key: http://www.tundraware.com/PGP/

PyPy 1.9 - Yard Wolf
by Maciej Fijalkowski 08 Jun '12

08 Jun '12

==================== PyPy 1.9 - Yard Wolf ==================== We're pleased to announce the 1.9 release of PyPy. This release brings mostly bugfixes, performance improvements, other small improvements and overall progress on the `numpypy`_ effort. It also brings an improved situation on Windows and OS X. You can download the PyPy 1.9 release here: http://pypy.org/download.html .. _`numpypy`: http://pypy.org/numpydonate.html What is PyPy? ============= PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7. It's fast (`pypy 1.9 and cpython 2.7.2`_ performance comparison) due to its integrated tracing JIT compiler. This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. Windows 64 work is still stalling, we would welcome a volunteer to handle that. .. _`pypy 1.9 and cpython 2.7.2`: http://speed.pypy.org Thanks to our donors ==================== But first of all, we would like to say thank you to all people who donated some money to one of our four calls: * `NumPy in PyPy`_ (got so far $44502 out of $60000, 74%) * `Py3k (Python 3)`_ (got so far $43563 out of $105000, 41%) * `Software Transactional Memory`_ (got so far $21791 of $50400, 43%) * as well as our general PyPy pot. Thank you all for proving that it is indeed possible for a small team of programmers to get funded like that, at least for some time. We want to include this thank you in the present release announcement even though most of the work is not finished yet. More precisely, neither Py3k nor STM are ready to make it in an official release yet: people interested in them need to grab and (attempt to) translate PyPy from the corresponding branches (respectively ``py3k`` and ``stm-thread``). .. _`NumPy in PyPy`: http://pypy.org/numpydonate.html .. _`Py3k (Python 3)`: http://pypy.org/py3donate.html .. _`Software Transactional Memory`: http://pypy.org/tmdonate.html Highlights ========== * This release still implements Python 2.7.2. * Many bugs were corrected for Windows 32 bit. This includes new functionality to test the validity of file descriptors; and correct handling of the calling convensions for ctypes. (Still not much progress on Win64.) A lot of work on this has been done by Matti Picus and Amaury Forgeot d'Arc. * Improvements in ``cpyext``, our emulator for CPython C extension modules. For example PyOpenSSL should now work. We thank various people for help. * Sets now have strategies just like dictionaries. This means for example that a set containing only ints will be more compact (and faster). * A lot of progress on various aspects of ``numpypy``. See the `numpy-status`_ page for the automatic report. * It is now possible to create and manipulate C-like structures using the PyPy-only ``_ffi`` module. The advantage over using e.g. ``ctypes`` is that ``_ffi`` is very JIT-friendly, and getting/setting of fields is translated to few assembler instructions by the JIT. However, this is mostly intended as a low-level backend to be used by more user-friendly FFI packages, and the API might change in the future. Use it at your own risk. * The non-x86 backends for the JIT are progressing but are still not merged (ARMv7 and PPC64). * JIT hooks for inspecting the created assembler code have been improved. See `JIT hooks documentation`_ for details. * ``select.kqueue`` has been added (BSD). * Handling of keyword arguments has been drastically improved in the best-case scenario: proxy functions which simply forwards ``*args`` and ``**kwargs`` to another function now performs much better with the JIT. * List comprehension has been improved. .. _`numpy-status`: http://buildbot.pypy.org/numpy-status/latest.html .. _`JIT hooks documentation`: http://doc.pypy.org/en/latest/jit-hooks.html JitViewer ========= There will be a corresponding 1.9 release of JitViewer which is guaranteed to work with PyPy 1.9. See the `JitViewer docs`_ for details. .. _`JitViewer docs`: http://bitbucket.org/pypy/jitviewer Cheers, The PyPy Team
