* DEP: Deprecate the oldnumeric and numarray modules.Charles Harris2013-06-101-0/+6
| | | | | | | | | The numarray and oldnumeric modules are deprecated. This is a bit tricky as raising a DeprecationWarning on import causes an error when tests are run. To deal with that, a ModuleDeprecationWarning class is added to numpy and NoseTester is modified to ignore that warning during testing. Closes #2905
* MAINT: Apply 2to3 idioms fixer.Charles Harris2013-05-023-4/+4
| | | | | | | | | | | | | | | | | | | 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.
* 2to3: Apply the `numliterals` fixer and skip the `long` fixer.Charles Harris2013-04-132-3/+4
| | | | | | | | | | | | | | | | | | | The numliterals fixer replaces the old style octal number like '01' by '0o1' removes the 'L' suffix. Octal values were previously mistakenly specified in some dates, those uses have been corrected by removing the leading zeros. Simply Removing the 'L' suffix should not be a problem, but in some testing code it looks neccesary, so in those places the Python long constructor is used instead. The 'long' type is no longer defined in Python 3. Because we need to have it defined for Python 2 it is added to numpy/compat/np3k.py where it is defined as 'int' for Python 3 and 'long' for Python 2. The `long` fixer then needs to be skipped so that it doesn't undo the good work. Closes #3074, #3067.
* 2to3: apply `dict` fixer.Charles Harris2013-04-061-3/+3
| | | | | | | | | | | | | | | 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 Harris2013-04-0619-43/+43
| | | | | | | Add `print_function` to all `from __future__ import ...` statements and use the python3 print function syntax everywhere. Closes #3078.
* 2to3: Apply `imports` fixer.Charles Harris2013-04-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Harris2013-03-2818-31/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Harris2013-03-0119-15/+30
| | | | | | | | 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.
* 2to3: apply exec fixer results.Charles Harris2013-02-281-1/+1
| | | | This changes the `exec` command to the `exec` function.
* DEP: Remove scons related files and code.Charles Harris2013-01-133-23/+0
| | | | | | | | | This removes files and code supporting scons builds. After this change numpy will only support builds using distutils or bento. The removal of scons has been discussed on the list several times and a decision has been made that scons support is no longer needed. This was originally discussed for numpy 1.7 and because the distutils and bento methods are still available we are skipping the usual deprecation period.

| | | | | | Also clean up its API slightly so that the caller passes in a name describing the array being checked which is used to generate an error message, rather than writing an error message from scratch.
* Funnel all assignments to PyArrayObject->base through a single pointNathaniel J. Smith2012-05-151-3/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch removes all direct assignments of non-NULL values to the 'base' field on PyArrayObjects. A new utility function was created to set up UPDATEIFCOPY arrays, and all assignments to 'base' were adjusted to use either PyArray_SetBaseObject or the new PyArray_SetUpdateIfCopyBase. One advantage of this is that it produces more consistent error handling. This error handling revealed a bug in the nditer code, which this patch does *not* yet fix. The bug is that npyiter_new_temp_array sometimes (when dealing with reversed axes) creates an array and then returns a view onto it. But, npyiter_allocate_arrays assumes that the array returned by npyiter_new_temp_array can have UPDATEIFCOPY set, which requires reassigning its 'base' field. Previously, this meant that the temporary array leaked. Now, it produces a ValueError. This code path doesn't seem to actually be hit very often; only one of the nditer tests fails because of the change. See numpy/core/tests/test_nditer.py:test_iter_array_cast_buggy
* Consolidate all array writeability checking in new PyArray_RequireWriteableNathaniel J. Smith2012-05-151-10/+8
| | | | | | | | | This is mostly a code cleanup, but it does have a user-visible effect in that attempting to write to a unwriteable array now consistently raises ValueError. (It used to randomly raise either ValueError or RuntimeError.) Passes numpy.test("full").

Removed numpy/testing/pkgtester.py since it just consisted of an import statement after porting SciPy r4424. Allow numpy.*.test() to accept the old keyword arguments (but issue a deprecation warning when old arguments are seen). numpy.*.test() returns a test result object as before. Fixed typo in distutils doc.
