* BUG: Missing dirichlet input validationKevin Sheppard2017-08-172-0/+12
| | | | | | | | Dirichlet does not validate inputs and hangs when values are zero. Adds check that values are strictly positive as required by the distribution. closes #2089
* 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.
* MAINT/DOC: Use builtin when np.{x} is builtins.{x}.Eric Wieser2017-08-051-10/+10
| | | | | | | 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 Harris2017-07-041-1/+1
| | | | | | | | | | | | | | | | | 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.

* MAINT: avoid memcpy when i == jYu Feng2017-04-101-0/+1
| | | | | | | | | | | | Valgrind complains about memcpy with overlapping address in mtrand.c It happens when i == j in this loop. Closer inspection the i == j iteration is not needed (it is a swap). So, skip it and avoid depending on undefined behavior of memcpy. related read: https://sourceware.org/bugzilla/show_bug.cgi?id=12518
* BUG: Check for errors when PyInt_AsLong is called in np.randomSimon Gibbons2017-04-022-9/+16
| | | | | | | | | After #8883 was merged it was noticed that the same problem was occuring with calls to PyInt_AsLong. Namely that PyErr_Occoured wasn't being checked if it returned -1 indicating an exception could have been thrown. This PR adds those checks as well as a regression test.

* BUG: Ensure Errors are correctly checked when PyFloat_AsDouble is called.Simon Gibbons2017-04-012-1/+15
| | | | | | | | | | | | | | There was an error in np.random.uniform where if np.random.uniform were called with a type that throwed exceptions when it was converted to a float this exception wouldn't be raised. This bug was due to an issue where PyFloat_AsDouble was called but no check for PyErr_Occurred was performed after. This PR fixes the issue by ensuring that Cython will always emit a call to PyErr_Occurred if PyFloat_AsDouble returns -1.0 Fixes: #8865

* MAINT: Remove asbytes where a b prefix would sufficeEric Wieser2017-03-251-2/+1
| | | | | | | | Since we only need to support python 2, we can remove any case where we just pass a single string literal and use the b prefix instead. What we can't do is transform asbytes("tests %d" % num), because %-formatting fails on bytes in python 3.x < 3.5.

| | * commit BLD: AIX uses the flag _LARGE_FILES to ensure proper prototype ↵Michael Felt2016-10-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | declarations The problem this fix resolves is to ensure that 32-bit and 64-bit functions (e.g., fclear() and fclear64()) to access/manipulate "large files" are defined properly - much as GNU and other platforms use one or more of the defines _FILE_OFFSET_BITS, _LARGEFILE_SOURCE, and _LARGEFILE64_SOURCE. Without this fix the numpy code only defines flags that are not recognized in the AIX environment and have no effect in anyway. The fix applies the AIX convention and does not "export" any of the flags currently exported. For all other platforms the current flags: _FILE_OFFSET_BITS, _LARGEFILE_SOURCE, and _LARGEFILE64_SOURCE are "exported". This fix should not have any impact or side-effect based on the version of python used. History: Starting around 1997 AIX started supporting so-called "large files", i.e., length > signed 32-bit. In the period 1997-1998 the flag _LARGE_FILES was established to simplify porting 32-bit applications to 64-bit. The convention is to define _LARGE_FILES before including any "system include files" either as an argument to ${CC} (e.g., in ${CFLAGS} or as the first #define in every source file. This is to ensure that that no relevant function calls would be redefined later in the build process.

| * | BUG: Fix segfaults in np.random.shuffleSimon Gibbons2016-06-102-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | np.random.shuffle will allocate a buffer based on the size of the first element of an array of strings. If the first element is smaller than another in the array this buffer will overflow, causing a segfault when garbage is collected. Additionally if the array contains objects then one would be left in the buffer and have it's refcount erroniously decrimented on function exit, causing that object to be deallocated too early. To fix this we change the buffer to be an array of int8 of the the size of the array's dtype, which sidesteps both issues. Fixes #7710
