* MAINT: Various minor code cleanups.Charles Harris2017-11-242-62/+73

* ENH: Add encoding option to numpy text IO.Julian Taylor2017-11-212-93/+422
| | | | | | | | | | | This modifies loadtxt and genfromtxt in several ways intended to add unicode support for text files by adding an `encoding` keyword to np.load, np.genfromtxt, np.savetxt, and np.fromregex. The original treatment of the relevant files was to open them as byte files, whereas they are now opened as text files with an encoding. When read, they are decoded to unicode strings for Python3 compatibility, and when written, they are encoded as specified. For backward compatibility, the default encoding in both cases is latin1.

| | | | | | | | | | | | | | | | | | 2d arrays would work, but in unpredictable and undocumented ways. This at least makes gh-9401 give a better error message.

| | | | | | | | | | | | | | | savetxt does not support saving arrays of dimension 0 or higher than 2. This pull request improves the message of the error raised.
* | | ENH: Align data in np.save() at 64 bytes (#9025)John Zwinck2017-09-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, saving format version 1 would align to 16 bytes, and saving version 2 would align improperly (bug #8085). Alignment is now always at least 64 bytes in either version, which supports memory mapping of the saved files on Linux, where mmap() offset must be a multiple of the page size. Why 64 bytes? Simply because we don't know of a case where more is needed. AVX alignment is 32 bytes; AVX-512 is 64. Fixes #8085, closes #8598.

| * | | TST, MAINT: Add `__init__.py` files to tests directories.Charles Harris2017-08-061-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows pytest to run with duplicate test file names. Note that `python <path-to-test-file>` no longer works with this change, nor will a simple `pytest numpy`, because numpy is imported from the numpy repository. However, `python runtests.py` and `>>> numpy.test()` are still available.

|/ / / | | | | | | | | | | | | | | | I don't know what that argument was used for, but it showis up in old tests and is not explicitly used within the tests. I assume it was part of an old testing framework and is now longer needed.
* | | MAINT/DOC: Use builtin when np.{x} is builtins.{x}.Eric Wieser2017-08-055-36/+36
| | | | | | | | | | | | | | | | | | | | | This is the case for x in {int, bool, str, float, complex, object}. Using the np.{x} version is deceptive as it suggests that there is a difference. This change doesn't affect any external behaviour. The `long` type is missing in python 3, so np.long is still useful

| * | | MAINT: Rearrange files in numpy/testing module.Charles Harris2017-07-042-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aim here is to separate out the nose dependent files prior to adding pytest support. This could be done by adding new files to the general numpy/testing directory, but I felt that it was to have the relevant files separated out as it makes it easier to completely remove nose dependencies when needed. Many places were accessing submodules in numpy/testing directly, and in some cases incorrectly. That presented a backwards compatibility problem. The solution adapted here is to have "dummy" files whose contents will depend on whether of not pytest is active. That way the module looks the same as before from the outside. In the case of numpy itself, direct accesses have been fixed. Having proper `__all__` lists in the submodules helped in that.

* | | | BUG: recfunctions.join_by fails when key is a subdtypeEric Wieser2017-07-011-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems that working with .descr is a generally terrible idea. Instead we introduce `get_fieldspec`, which returns a list of 2-tuples, encapsulating subdtypes. This also means that np.core.test_rational.rational survives a roundtrip - its .descr is 'V8', which ddoesn't survive

* | DEP: Deprecate incorrect behavior of expand_dims.Charles Harris2017-05-171-1/+22
|/ | | | | | | | | | | Expand_dims works as documented when the index of the inserted NewAxis in the resulting array satisfies -a.ndim - 1 <= index <= a.ndim. However, when index > a.ndim index is replaced by a.ndim and, when index < -a.ndim - 1, it is replaced by index + a.ndim + 1, which may be negative and results in incorrect placement. The latter two cases are now deprecated. Closes #9100.
