| | | | | | | | | | | | | | | | Fix bug where nanpercentile would crash with an all-nan slices when given multiple percentiles. Also corrects behavior where array sizes different from numpy.percentile would be returned with keepdims enabled. Fix #5760

* | DOC, MAINT: Enforce np.ndarray arg for np.put and np.placegfyoung2016-01-142-4/+4
|/ | | | | | | np.put and np.place do something only when the first argument is an instance of np.ndarray. These changes will cause a TypeError to be thrown in either function should that requirement not be satisfied.
* MAINT: Simplify some tests using temppath context manager.Charles Harris2015-12-261-55/+31
| | | | | | | | | | | | | | | | | | | | | | | | This replaces code of the pattern ``` fd, name = tempfile.mkstemp(...) os.close(fd) try: do stuff with name finally: os.remove(name) ``` with ``` with temppath() as name: do stuff with name ``` A few more complicated cases are also handled. The remains some particularly gnarly code the could probably be refactored to use temppath, but that is a more demanding project.

* | BUG: Quick and dirty fix for interp.Charles Harris2015-12-071-4/+36
|/ | | | | | | | | | | The original had incorrect comparisons involving <=, <, and also failed when the number of data points was 2. This fixes the use of the comparisons and uses linear search for fewer than 5 data points. The whole routine needs a simplified rewrite, but this takes care of the bug. Closes #6468.

* DEP: Remove FutureWarning from np.lib.split and go to future.Charles Harris2015-10-301-18/+12
| | | | | | | | | | | | | | | Previously an empty array resulting from split always had dimension 1-D. In Numpy 1.9 a FutureWarning was raised to notify users that it was planned to preserve the dimensions of empty arrays in a future numpy release. This removes the FutureWarning and implements preservation of dimensions. Note that there was a bug in numpy 1.9 and the dimensions of empty arrays was already preserved in some cases and no warning was issued. This PR fixes that inconsistency by preserving the dimensions in all cases rather than fixing the bug, as the dimension preserving behavior was already depended on by some users. See the discussion in gh-6575 about this change.
* TST: attempt to make test_load_refcount deterministicNathaniel J. Smith2015-10-281-6/+11

The affected deprecation tests have been been changed to check for raised errors instead, but remain in test_deprecations.py for the moment. They will be moved when the conversion of the remaining indexing deprecations is complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Those test functions were incorrectly importing test functions from numpy/ma/testutils that were actually not defined there, but rather in numpy/testing. That did not cause an error when testutils was '*' importing all the test functions, but it was deceptive as some of the functions might appear to support masked arrays when they do not.
