Shed Skin 0.1 (Default branch)

Shed Skin is an experimental (restricted-)Python-to-C++ compiler. It accepts pure but implicitly statically typed Python programs and generates optimized C++ code. The result can be further compiled to stand-alone programs or extension modules. For a set of 16 non-trivial test programs, measurements show a typical speedup of 2-40 over Psyco, about 10 on average, and 2-220 over CPython, about 35 on average. Not all Python features are supported, and only a subset of about 17 library modules, such as re and random. License: GNU General Public License v3 Changes:
Improved support for 'os' (UNIX). The addition of a JPEG decoder (1200 lines) and some other programs to the set of example programs. Extension module fixes. Improved compiler flags under OS X. An important type inference fix. Improved variable overloading. Casting improvements. Fixes for setslice and delslice corner cases. xrange returns an xrange object, not iterator. There are several minor bugfixes. Image

Hello All, Here is a snipet from our cluster.log, I was wondering if anyone could shed some light on what may have caused the failover. The first two lines indicate a possible memory issue which I am currently looking into. Thanks. (0 Replies)

PYTHON-COVERAGE(1)					      General Commands Manual						PYTHON-COVERAGE(1)

NAME
python-coverage - measure code coverage of Python program execution SYNOPSIS
python-coverage -x module.py [ARG...] python-coverage -e python-coverage -r [-m] python-coverage -a [file...] DESCRIPTION
python-coverage executes a Python program and measures which of its statements are executed and which are not. It stores the information in the file .coverage in the current working directory. OPTIONS
-e Erase the .coverage file. -x Execute a Python module, giving it the remaining command line arguments. -r Produce a coverage report. -m With -r, show the line numbers that were missed by the execution. -a Annotate source files. For each source file foo, produce foo,cover, with executed lines prefixed by ">" and non-executed by "!". --help Produce a help summary. It might be more helpful than this manual page. AUTHOR
The python-coverage command is a one-line Python script which calls the coverage.py Python module to do all the work. The module was rigi- nally developed by Gareth Rees, and is now developed by Ned Batchelder. The module's home page is http://www.nedbatchelder.com/code/modules/coverage.html. This manual page was cobbled together by Lars Wirzenius for Debian, by copy-pasting from the help texts from the module. PYTHON-COVERAGE(1)
