* MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-051-2/+2
| | | | | | | Inheriting from object was necessary for Python 2 compatibility to use new-style classes. In Python 3, this is unnecessary as there are no old-style classes. Dropping the object is more idiomatic Python.
* MAINT: Remove unnecessary 'from __future__ import ...' statementsJon Dufresne2020-01-031-2/+0
| | | | | As numpy is Python 3 only, these import statements are now unnecessary and don't alter runtime behavior.

| * BUG: improve DataSource __del__Tyler Reddy2018-11-131-1/+1
| | | | | | | | | | | | | | | | * DataSource __del__ could raise an AttributeError if __init__ failed for any reason; __del__ now gracefully handles the case where __init__ fails, as happens in the internals of refguide_check when handling DataSource with an unexpected kwarg
* | ENH: set correct __module__ for objects in numpy's public APIStephan Hoyer2018-11-131-1/+6
|/ | | | | | | | | | | | | Fixes GH-12271 Tests verify that everything in ``dir(numpy)`` either has ``__module__`` set to ``'numpy'``, or appears in an explicit whitelist of undocumented functions and exported bulitins. These should eventually be documented or removed. I also identified a handful of functions for which I had accidentally not setup dispatch for with ``__array_function__`` before, because they were listed under "ndarray methods" in ``_add_newdocs.py``. I guess that should be a lesson in trusting code comments :).
* BUG: Fix regression in loadtxt for bz2 text files in Python 2.Charles Harris2018-08-101-3/+5
| | | | | | | | | | | Text bz2 files are not well supported in Python2, and, following the NumPy upgrade in text handling, loadtxt was raising an error when they were detected. This led to problems for those few who were using such files. This patch is a quick fix that issues a RuntimeWarning, then opens those files under the assumption that they are latin1 encoded. Caveat emptor. Closes #11633.

* DOC: Add some docstrings and edit others.Charles Harris2017-11-211-2/+42
| | | | | | | Add docstrings for some of the support functions in _datasource and npyio in order to aid future maintainers. [ci skip]
* ENH: Add encoding option to numpy text IO.Julian Taylor2017-11-211-14/+74
| | | | | | | | | | | 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.

| | | | | | Some of those problems look like potential coding errors. In those cases a Fixme comment was made and the offending code, usually an unused variable, was commented out.
* BUG: close file-like objects returned by urlopencgohlke2013-10-151-0/+2
| | | Fix `ResourceWarning: unclosed file` on Python 3
* 2to3: Apply urllib fixer.Charles Harris2013-04-141-4/+12
| | | | | | | | | | | Various functions have been moved around in the stdlib for Python 3, this fixes that up so that the code is valid in both Python 2 and Python 3. Note: monkey patching the stlib urlopen for testing looks a bit hokey to me, but I don't see an easier, more reliable way to do the test. Closes #3090.
* 2to3: apply `dict` fixer.Charles Harris2013-04-061-1/+1
| | | | | | | | | | | | | | | In Python3 `dict.items()`, `dict.keys()`, and `dict.values()` are iterators. This causes problems when a list is needed so the 2to3 fixer explicitly constructs a list when is finds on of those functions. However, that is usually not necessary, so a lot of the work here has been cleaning up those places where the fix is not needed. The big exception to that is the `numpy/f2py/crackfortran.py` file. The code there makes extensive use of loops that modify the contents of the dictionary being looped through, which raises an error. That together with the obscurity of the code in that file made it safest to let the `dict` fixer do its worst. Closes #3050.
* 2to3: Apply `print` fixer.Charles Harris2013-04-061-1/+1
| | | | | | | Add `print_function` to all `from __future__ import ...` statements and use the python3 print function syntax everywhere. Closes #3078.
* 2to3: Apply `imports` fixer.Charles Harris2013-04-021-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The `imports` fixer deals with the standard packages that have been renamed, removed, or methods that have moved. cPickle -- removed, use pickle commands -- removed, getoutput, getstatusoutput moved to subprocess urlparse -- removed, urlparse moved to urllib.parse cStringIO -- removed, use StringIO or io.StringIO copy_reg -- renamed copyreg _winreg -- renamed winreg ConfigParser -- renamed configparser __builtin__ -- renamed builtins In the case of `cPickle`, it is imported as `pickle` when python < 3 and performance may be a consideration, but otherwise plain old `pickle` is used. Dealing with `StringIO` is a bit tricky. There is an `io.StringIO` function in the `io` module, available since Python 2.6, but it expects unicode whereas `StringIO.StringIO` expects ascii. The Python 3 equivalent is then `io.BytesIO`. What I have done here is used BytesIO for anything that is emulating a file for testing purposes. That is more explicit than using a redefined StringIO as was done before we dropped support for Python 2.4 and 2.5. Closes #3180.
* 2to3: Use absolute imports.Charles Harris2013-03-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.Charles Harris2013-03-011-0/+1
| | | | | | | | 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.
