* BUG: Fix race condition with new FFT cacheLion Krischer2016-06-072-6/+14
| | | | | | There is now a lock around cache accesses ensuring thread safety. The size of a cache entry is now also calculated by summing over all arrays in the list.
* ENH: Changing FFT cache to a bounded LRU cacheLion Krischer2016-06-063-2/+152
| | | | | | | | Replaces the simple dictionary caches for the twiddle factors of numpy.fft to bounded LRU (least recently used) caches. The caches can thus no longer grow without bounds. See #7686.

* | BUG: Rename fft C functions to avoid name conflictRyan Nelson2014-12-043-34/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolves issue #565. The public fft functions defined in fftpack.c have name conflicts on certain systems, so the prefix "npy_" was added to these functions. Added NPY_VISIBILITY_HIDDEN to the public functions in both fftpack.h and fftpack.c. This required rearranging the includes at the beginning of fftpack_litemodule.c so that this macro was properly defined. In addition, Python.h and numpy/ndarraytypes.h were included in the fftpack.h. One function, rfftb1, was flagged as `static` as it was not exported in the header. Build and tests pass using both Python 2.7.8 and Python 3.4.2.

| * BUG: fix crash when sending interrupt signal to fft functionsJulian Taylor2014-05-091-12/+12
| | | | | | | | | | | | | | | | | | | | the SIGINT handling code must be in the GIL released section so the longjmp does not skip the retaking. This implies that the signal handlers must use thread local storage to avoid a crash when sending interrupt to threaded fft functions. Distribution of SIGINT to each threads must be handled by the application as only the master thread receives it Closes gh-4634

| | | | | | | 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.

* 2to3: Apply types fixer.Charles Harris2013-04-141-6/+7
| | | | | | | | | | | | | | | | | | | | 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 `print` fixer.Charles Harris2013-04-067-7/+7
| | | | | | | Add `print_function` to all `from __future__ import ...` statements and use the python3 print function syntax everywhere. Closes #3078.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
