|\ \ | | | | | | Revert changes to contiguous flags definition while creating NPY_TEST_UNSAFE_STRIDES
| * | API: Implement new flags API with NPY_RELAXED_STRIDES_CHECKINGSebastian Berg2013-04-018-27/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This largly reverts the changes to the flags setting api making the newer preferable unsafe flags setting available through the NPY_RELAXED_STRIDES_CHECKING eviroment variable. This variable is meant for testing if code will stop working when the flags definition is changed. The old definition is modified in some details to previously to enforce safer strides (which was not the case before). This means that ndim==1 size==1 arrays are not necessarily considered contiguous. Also empty arrays are not considered contiguous in some cases that were contiguous before, and the rule that an array can only be both C and F-contiguous if it is one (or zero) dimensional is relaxed, as it is incorrect for size <= 1 arrays.
| * | ENH: Relax aligned flag for shape[i] <= 1Sebastian Berg2013-04-011-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | In this case, either the dimensions stride will never be used to access an element, so that it does not matter to the data alignment, or the array has a size of 0 and is thus never unaligned. Relaxed align flag is only active if NPY_RELAXED_STRIDES_CHECKING was set during compile time.
| * | BLD: Add NPY_RELAXED_STRIDES_CHECKING flagSebastian Berg2013-04-012-0/+16
| |/ | | | | | | | | | | | | | | | | | | This flag will toggle to a new definition for the contiguous flags where only the memory layout is forced to be correct. As a particular example this means that np.ones((3,1)) can be both C and F-Contiguous and its stride[-1] can be arbitrary but the array still contiguous. The flag will also make most new arrays be created with MAX_INTP as stride so that unsafe usage of the stride will surface more commonly.

| * | 2to3: Add `from __future__ import ...` to some files that were missed.Charles Harris2013-03-281-0/+2
| | | | | | | | | | | | | | | | | | | | | With the exception of numpy/distutils/tests/test_exec_command.py, all of these files are script files in tools/osxbuild and tools/win32build. The import in the script files omits `absolute_import` as they are not part of a package.
| * | 2to3: Use absolute imports.Charles Harris2013-03-28340-624/+619
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| * | | BUG: Raise immediate error in ctypes.load_library when library is bad.Charles Harris2013-04-011-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fixup of PR #475 due to JeromeRoy. The problem addressed is that when multiple errors were encountered attempting to import a library file, only the last one was preserved. The proposed fix is to raise an error immediately when a file of the correct name fails to import, and raise a later error if no file is found but no errors are raised in the search. Closes #474, #475.

| | |_|_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This checks if the previous time around, the buffers were filled with as much data as they would be filled this time around. Since This is difficult for the initial loop before reusing is activated because in that case the buffer may be larger then just the first outer reduce dimension. In that case do not allow reuse unless the index along that dimension was 0. When the inner reduce index is not 0, then also the reusing of the buffer is dangerous.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also uses oa_ndim == -1 to signal no op_axes were given. This is slightly cleaner inside pywrap itself and is a cleaner signal for the iterator.
| * | | | | API: Make nditer support ndim == 0 for 0-d iterations.Sebastian Berg2013-03-036-83/+109

However there is a conceptionally there are no axes for the 0-d case, and no axesdata needs to be used. This still uses the first axisdata. Which means that in a few places ndim == 0 is special cased or special cased to act like ndim == 1. It would probably be a little cleaner to to use the base pointers directly in the 0-d case and no axes iteration at all. That would require similar special cases though. This also makes oa_ndim == -1 the "correct" way to signal that no op_axes are given with oa_ndim == 0 being, for the time being, dual use. Either meaning that nothing may be given, or if something something was given enforcing a 0-d iteration. The necessary changes to the ufunc machinery are also done. Documented that the dtype transfer functions do not handle the scalar case unless even shape is set.

This has two consequence for code: 1) Where a list is needed `list(range(...))` must be used. 2) `xrange` must be replaced by `range` Both of these changes also work in python2 and this patch makes both. There are three places fixed that do not need it, but I left them in so that the result would be `xrange` clean. Closes #3092
