* | MAINT: move the special case for void comparison before the regular caseNathaniel J. Smith2015-06-131-3/+26
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The ndarray richcompare function has special case code for handling void dtypes (esp. structured dtypes), since there are no ufuncs for this. Previously, we would attempt to call the relevant ufunc (e.g. np.equal), and then when this failed (as signaled by the ufunc returning NotImplemented), we would fall back on the special case code. This commit moves the special case code to before the regular code, so that it no longer requires ufuncs to return NotImplemented. Technically, it is possible to define ufunc loops for void dtypes using PyUFunc_RegisterLoopForDescr, so technically I think this commit changes behaviour: if someone had registered a ufunc loop for one of these operations, then previously it might have been found and pre-empted the special case fallback code; now, we use the special-case code without even checking for any ufunc. But the only possible use of this functionality would have been if someone wanted to redefine what == or != meant for a particular structured dtype -- like, they decided that equality for 2-tuples of float32's should be different from the obvious thing. This does not seem like an important capability to preserve. There were also several cases here where on error, an array comparison would return a scalar instead of raising. This is supposedly deprecated, but there were call paths that did this that had no deprecation warning. I added those warnings.
* ENH: add clear_and_catch_warnings context managerMatthew Brett2015-03-141-1/+63
| | | | | | | Add context manager for tests that, on entry, clears record of any previous warnings from given modules, so that any warning raised in the context block does get raised, rather than suppressed by a previous warning causing an entry in the `__warningregistry_`` of the module.

| | | | | | | | | | | | The `max()` function previously used does not work with two array-like. `maximum()` does, and is what is essentially used in the code (`ref = nulp * np.spacing(np.where(ax > ay, ax, ay))`).

* BUG: Force allclose logic to use inexact typeSebastian Berg2014-02-161-5/+9
| | | | | | Casting y to an inexact type fixes problems such as abs(MIN_INT) < 0, and generally makes sense since the allclose logic is inherently for float types.
* DEP: Deprecate boolean `-` operationsSebastian Berg2014-02-121-1/+6
| | | | | | | | | | | | Boolean - is not well defined, especially the unary and binary operator are not compatible. In general boolean minus seems to have no real application and does not do what might be expected. All "allclose" type functions (numpy, tests, masked) have to now check for boolean to avoid the deprecation warning. In the future one could think about removing it again and just allowing the upcast.
* ENH: accept callable as message in assert_Julian Taylor2013-10-191-1/+6
| | | | | | | Allows deferring evaluation until failure. Used for blocked minmax test which evaluate array representations for the error message many thousand times accumulating to a full second useless runtime.

* TST: speed up some very slow testsJulian Taylor2013-09-241-1/+1
| | | | | | | | | Minimize alignment combinations to useful set with SSE, might need to be revisited if we add AVX support. Move large data test_zeros test to slow and drop the extremely slow count_nonzero() call. Rename gen_alignment_data to _gen_alignment_data (private) to reserve right to change it, e.g. add min_size.

| | | | | | | Run the 2to3 ws_comma fixer on *.py files. Some lines are now too long and will need to be broken at some point. OTOH, some lines were already too long and need to be broken at some point. Now seems as good a time as any to do this with open PRs at a minimum.

* MAINT: remove unused and broken parts of numpy.testingRalf Gommers2013-08-101-3/+11

* MAINT: Remove uses of the WarningManager class.Charles Harris2013-07-121-17/+8
| | | | | | | | | | | | WarningManager was a workaround for the lack of the with statement in Python versions < 2.6. As those versions are no longer supported it can be removed. Deprecation notes are added to WarningManager and WarningMessage, but to avoid a cascade of messages in third party apps, no warnings are raised at this time, that can be done later. Closes #3519.
* MAINT: Use np.errstate context manager.Charles Harris2013-07-111-15/+5
| | | | | | | | | | | | | Now that Python < 2.6 is no longer supported we can use the errstate context manager in places where constructs like ``` old = seterr(invalid='ignore') try: blah finally: seterr(**old) ``` were used.
* DEP: Deprecate the oldnumeric and numarray modules.Charles Harris2013-06-101-0/+2
| | | | | | | | | 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

* ENH: vectorize sqrt ufunc using SSE2Julian Taylor2013-05-251-0/+67
| | | | | | | | | | | | | | | | | | specialize the sqrt ufunc for float and double and vectorize it using SSE2. improves performance by 4/2 for float/double if one is not memory bound due to non-cached data. performance is always better on all tested machines (amd phenom X2, intel xeon 5xxx/7xxx, core2duo, corei7) This version will not set errno on invalid input, but numpy only checks the fpu flags so the behavior is the same. In principle the compiler could autovectorize it when setting ffast-math (for no errno) and specializing the loop for the vectorizable strides and giving it some hints (restrict, __builtin_assume_aligned, etc.), but its simpler and more reliable to simply vectorize it by hand.
* 2to3: Apply types fixer.Charles Harris2013-04-141-4/+3
| | | | | | | | | | | | | | | | | | | | Python 3 removes the builtin types from the types module. The types fixer replaces such references with the builtin types where possible and also takes care of some special cases: types.TypeNone <- type(None) types.NotImplementedType <- type(NotImplemented) types.EllipsisType <- type(Ellipsis) The only two tricky substitutions are types.StringType <- bytes types.LongType <- int These are fixed up to support both Python 3 and Python 2 code by importing the long and bytes types from numpy.compat. Closes #3240.
* 2to3: Apply `map` fixer.Charles Harris2013-04-101-1/+2
| | | | | | | | | | | | | | | | | | | 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 `repr` fixer.Charles Harris2013-04-081-4/+4
| | | | | | | | | | | | This replaces python backtics with repr(...). The backtics were mostly used to generate strings for printing with a string format and it is tempting to replace `'%s' % repr(x)` with `'%r' % x`. That would work except where `x` happened to be a tuple or a dictionary but, because it would be significant work to guarantee that and because there are not many places where backtics are used, the safe path is to let the repr replacements stand. Closes #3083.
* 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.
