* DEP: Remove FutureWarning from np.lib.split and go to future.Charles Harris2015-10-301-18/+12
| | | | | | | | | | | | | | | Previously an empty array resulting from split always had dimension 1-D. In Numpy 1.9 a FutureWarning was raised to notify users that it was planned to preserve the dimensions of empty arrays in a future numpy release. This removes the FutureWarning and implements preservation of dimensions. Note that there was a bug in numpy 1.9 and the dimensions of empty arrays was already preserved in some cases and no warning was issued. This PR fixes that inconsistency by preserving the dimensions in all cases rather than fixing the bug, as the dimension preserving behavior was already depended on by some users. See the discussion in gh-6575 about this change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The deprecated operations changed to errors are * Conversion of floats and booleans to npy_intp indexes. * Conversion of single element integer arrays of ndim > 1 to indexes. * Multiple ellipsis in index. The affected deprecation tests have been been changed to check for raised errors instead, but remain in test_deprecations.py for the moment. They will be moved when the conversion of the remaining indexing deprecations is complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Those test functions were incorrectly importing test functions from numpy/ma/testutils that were actually not defined there, but rather in numpy/testing. That did not cause an error when testutils was '*' importing all the test functions, but it was deceptive as some of the functions might appear to support masked arrays when they do not.

| * | ENH: PyArray_FromInterface checks descr if typestr is np.voidjaimefrio2015-03-081-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the 'typestr' member of the __array_interface__ dictionary defines a np.void dtype, check the 'descr' member, and if it is a valid dtype description and it is not the default one, use it to construct the dtype for the array to return. This fixes #5081, as as_strided no longer has to worry about changing the dtype of the return.
* | | BUG: loadtxt fails with complex data in Python 3.Charles Harris2015-03-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that the Python complex type constructor only accepts a pair of numbers or a string, unlike other numeric types it does not work with byte strings. The numpy error is subtle, as loadtxt opens the file in the default text mode, but then converts the input lines to byte strings when they are split into separate values. The fix here is to convert the values back to strings in the complex converter. Closes #5655.

* | | BUG: genfromtxt gave OverflorError for large integersThomas Robitaille2015-03-062-4/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fix StringConverter to avoid OverflowError in genfromtxt. Before, int(2**66) would work (and return a ‘long’) but then np.array([2**66], dtype=np.integer) would not work and return an OverflowError which would propagate to genfromtxt. This commit fixes this by ensuring testing in advance whether an OverflowError will occur. In addition, this adds an explicit np.int64 entry on systems where integer means int32. Values larger than 2**63-1 will be cast as float. This includes a regression test and adds an entry to the release notes.
