delta/python-packages/numpy.git/tools/allocation_tracking, branch auto github.com: numpy/numpy.git BUG: disable garbage collector during memory allocation hook 2014-07-05T21:13:30+00:00 Julian Taylor jtaylor.debian@googlemail.com 2014-07-05T21:09:12+00:00 c9c53ea985565d7d78f23519b9c5db630ac76d3d When a cython object contains numpy arrays the pure python allocation hook can trigger during cythons __dealloc__ method and trigger a second deletion of the object currently being deleted. To minimize the probabily that that happens disable the garbage collector during the hook. As this involves python calls it is still possible that a double delete occurs but chances are lowered, a proper solution would be C only hook like python 3.4 tracemalloc module. Closes gh-4834

2to3: Apply `print` fixer. 2013-04-06T19:25:26+00:00 Charles Harris charlesr.harris@gmail.com 2013-04-06T19:25:26+00:00 bb726ca19f434f5055c0efceefe48d89469fcbbe Add `print_function` to all `from __future__ import ...` statements and use the python3 print function syntax everywhere. Closes #3078.

2to3: Use absolute imports. 2013-03-28T14:43:26+00:00 Charles Harris charlesr.harris@gmail.com 2013-03-28T03:49:08+00:00 d4b88c1dbd6898fb6fcebc97f36b421999340f71 The new import `absolute_import` is added the `from __future__ import` statement and The 2to3 `import` fixer is run to make the imports compatible. There are several things that need to be dealt with to make this work. 1) Files meant to be run as scripts run in a different environment than files imported as part of a package, and so changes to those files need to be skipped. The affected script files are: * all setup.py files * numpy/core/code_generators/generate_umath.py * numpy/core/code_generators/generate_numpy_api.py * numpy/core/code_generators/generate_ufunc_api.py 2) Some imported modules are not available as they are created during the build process and consequently 2to3 is unable to handle them correctly. Files that import those modules need a bit of extra work. The affected files are: * core/__init__.py, * core/numeric.py, * core/_internal.py, * core/arrayprint.py, * core/fromnumeric.py, * numpy/__init__.py, * lib/npyio.py, * lib/function_base.py, * fft/fftpack.py, * random/__init__.py Closes #3172

2to3: Put `from __future__ import division in every python file. 2013-03-01T18:22:47+00:00 Charles Harris charlesr.harris@gmail.com 2013-02-27T20:26:58+00:00 6aa264c4bad9c89ccdd9ecd5a1cb5ef10643ec51 This should be harmless, as we already are division clean. However, placement of this import takes some care. In the future a script can be used to append new features without worry, at least until such time as it exceeds a single line. Having that ability will make it easier to deal with absolute imports and printing updates.

Wrap hook functions with GIL, add example. 2012-06-18T09:50:28+00:00 Thouis (Ray) Jones thouis@gmail.com 2012-06-18T09:50:28+00:00 5b5a0f4999dfac66c9c27160737352c727a3517b Wraps the SetHook and calls to the hook with the GIL, to prevent races. Adds an example of using the interface for callbacks into python code.
