| * DOC: npyio.recfromcsv keyword argument changesYaron de Leeuw2014-02-281-0/+5
| | | | | | | | | | | | Added a note to recfromcsv about the `dtype` keyword, as suggested by @hpaulj. Also added a note to the release notes, about the change in the `update` keyword, as suggested by @charris.
| * MAINT (API?): organize npyio.recfromcsv defaultsYaron de Leeuw2014-02-281-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | Organizes the default kwargs in recfromcsv. Changes two undocumented kwargs behaviors: * previously, if a user set `names=None`, it was ignored and replaced with `names=True` * the `dtype` kwarg was ignored. If `update` was given, it was used as `dtype`, and if not, None was used. We can retain the `update` behavior by using `kwargs.setdefault("dtype",kwargs.get('update', None))`. This Closes #311 .

* MAINT: Apply 2to3 idioms fixer.Charles Harris2013-05-021-1/+1
| | | | | | | | | | | | | | | | | | | The idioms fixer makes the following replacements. 1) int <- bool 2) comparison or identity of types <- isinstance 3) a.sort() <- sorted(a) There were two problems that needed to be dealt with after the application of the fixer. First, the replacement of comparison or identity of types by isinstance was not always correct. The isinstance function returns true for subtypes whereas many of the places where the fixer made a substitution needed to check for exact type equality. Second, the sorted function was applied to arrays, but because it treats them as iterators and constructs a sorted list from the result, that is the wrong thing to do. Closes #3062.
* MAINT: Remove unneeded version checks.Charles Harris2013-04-241-2/+1
| | | | | | Now that only Python versions 2.6-2.7 and 3.2-3.3 are supported some version checks are no longer needed. This patch removes them so as to clean up the code.
* MAINT: Use from future_builtins zip and map.Charles Harris2013-04-211-3/+2
| | | | | | For Python versions 2.6 and 2.7 the iterator forms of zip and map can be imported from future_builtins. That is done here so as to avoid using itertools.{izip, imap}.
* 2to3: Apply unicode fixer.Charles Harris2013-04-211-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | The unicode fixer strips the u from u'hi' and converts the unicode type to str. The first won't work for Python 2 and instead we replace the u prefix with the sixu function borrowed from the six compatibility package. That function calls the unicode constructor with the 'unicode_escape' encoder so that the many tests using escaped unicode characters like u'\u0900' will be handled correctly. That makes the sixu function a bit different from the asunicode function currently in numpy.compat and also provides a target that can be converted back to the u prefix when support for Python 3.2 is dropped. Python 3.3 reintroduced the u prefix for compatibility. The unicode fixer also replaces 'unicode' with 'str' as 'unicode' is no longer a builtin in Python 3. For code compatibility, 'unicode' is defined either as 'str' or 'unicode' in numpy.compat so that checks like if isinstance(x, unicode): ... will work properly for all python versions. Closes #3089.
* 2to3: Apply next fixer.Charles Harris2013-04-151-4/+4
| | | | | | | | | | | | | | The next builtin has been available since Python 2.6 and allows `it.next()` to be replaced by `next(it)`. In Python 3 the `next` method is gone entirely, replaced entirely by the `__next__` method. The next fixer changes all the `it.next()` calls to the new form and renames the `next` methods to `__next__`. In order to keep Numpy code backwards compatible with Python 2, a `next` method was readded to all the Numpy iterators after the fixer was run so they all contain both methods. The presence of the appropriate method could have been made version dependent, but that looked unduly complicated. Closes #3072.

|\ | | | | 2to3: Apply zip fixer.
| * 2to3: Apply zip fixer.Charles Harris2013-04-131-6/+6
| | | | | | | | | | | | | | | | | | | | In Python 3 zip returns an iterator instead of a list. Consequently, in places where an iterator won't do it must be enclosed in list(...). Lists instead of iterators are also used in array constructors as using iterators there usually results in an object array containing an iterator object. Closes #3094
* | 2to3: Apply basestring fixer.Charles Harris2013-04-131-1/+1
|/ | | | | | | | | | | The basestring class is not defined in Python 3 and the fixer replaces it with str. In order to have a common code base we define basestring in numpy/compat/py3k.py to be str when the Python version is >= 3, otherwise basestring and import it where needed. That works for most cases, but there are a few files where the version dependent define needs to be in the file. Closes #3042.
* 2to3: Apply itertools fixer.Charles Harris2013-04-121-1/+3
| | | | | | | | | | | | | In Python 3 zip, map, and filter are all iterators, consequently the itertools variants izip, imap, and ifilter have been removed and the itertools fixer replaces them with the unprefixed names. Because the places where the iterator variants are used in current look like places where the iterator version might be useful, the approach taken here is to define the prefixed versions to the unprefixed versions for Python 3, but otherwise import them from itertools. Closes #3233.
* 2to3: Apply `map` fixer.Charles Harris2013-04-101-10/+11
| | | | | | | | | | | | | | | | | | | In Python 3 `map` is an iterator while in Python 2 it returns a list. The simple fix applied by the fixer is to inclose all instances of map with `list(...)`. This is not needed in all cases, and even where appropriate list comprehensions may be preferred for their clarity. Consequently, this patch attempts to use list comprehensions where it makes sense. When the mapped function has two arguments there is another problem that can arise. In Python 3 map stops execution when the shortest argument list is exhausted, while in Python 2 it stops when the longest argument list is exhausted. Consequently the two argument case might need special care. However, we have been running Python3 converted versions of numpy since 1.5 without problems, so it is probably not something that affects us. Closes #3068
* 2to3: apply `dict` fixer.Charles Harris2013-04-061-2/+2
| | | | | | | | | | | | | | | 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 Harris2013-04-021-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Harris2013-03-281-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Replace xrange by range and use list(range(...)) where neededCharles Harris2013-03-271-3/+3
|/ | | | | | | | | | | | | | | In python3 range is an iterator and `xrange` has been removed. 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
* 2to3: Put `from __future__ import division in every python file.Charles Harris2013-03-011-0/+2
| | | | | | | | 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.
