* cmake: change how test files are build when cross compilingPhilip Balister2021-12-031-0/+3
| | | | | | | | | | | | | | | | | | | | * When cross compiling gnuradio, change how the test files are built. Normally, the gnuradio QA code expects to run in the build tree. For the cross compilng case, we cannot run the QA code during the build process. The changes here allow the creation of an additional package that can be installed on a target that will run the QA code against the installed libraries. Major changes are not using full paths to test files (since they include paths that only exist on the build machine) and not setting environment variables in the shell files to force the QA code to use code in the build tree. This patch disables the C++ only tests, these need some work and then they can be added back for the cross compile case. Signed-off-by: Philip Balister <philip@balister.org>

* gr-filter: update for additional window valuesJacob Gilbert2021-01-252-17/+17
| | | | | | Recently added window options include several additional windows that take a configuration parameter. This updates this parameter from 'beta' which was previously used only for Kaiser windows to a generic 'param' which makes sense for any window requiring a configuration parameter. The default values remain 6.76 which is not legal for the Tukey window but this error will be caught if the default is used; this is a reasonable cost for backward compatability.

* filter: Fix polyphase_filterbank for MSVC, w/ default move constructor.Ryan Volz2021-01-112-2/+2
| | | | | | | | | | | | | | Because of the deleted copy constructor (previously implicit, now made explicit in this commit to match fir_filter.h), polyphase_filterbank.cc fails to compile with MSVC trying to use the fft_filter_ccf copy constructor. Explicitly declaring a default move constructor fixes this by allowing it to use the move constuctor instead, which is the behavior we want. It's a mystery why MSVC requires this and other compilers don't, but it works. See #3892 for similar discussion and change for other filter classes. Signed-off-by: Ryan Volz <ryan.volz@gmail.com>

| | | | | | | | The bulk of the rational resampler code is named rational_resampler_base and only in Python is the automatic designing of filters if taps are not specified. This pushes that code into the C++ classes (which get binded) so rational_resampler.py can go away, removing a layer of wrapping

| | | | | | | | | | | | | | | | All of the removed `from __future__ import` were needed in older versions of Python (mostly 2.5.x and below) but later became mandatory in most versions of Python 3 hence are not necessary anymore. More specifically, according to __future__.py[1]: - unicode_literals is part of Python since versions 2.6.0 and 3.0.0; - print_function is part of Python since versions 2.6.0 and 3.0.0; - absolute_import is part of Python since versions 2.5.0 and 3.0.0; - division is part of Python since versions 2.2.0 and 3.0.0; Get rid of those unnecessary imports to slightly clean up the codebase.

* filter: fix FFT frequency range calculationClayton Smith2020-07-061-2/+1
| | | | | | | | | | | | | When using certain sample rate values (e.g. 320001), the Filter Design Tool fails with "ValueError: operands could not be broadcast together with shapes (9999,) (10000,)". This occurs because the self.freq array in the get_fft function has one too many values. The self.freq array is generated using numpy.arange. Its documentation warns: "When using a non-integer step, such as 0.1, the results will often not be consistent. It is better to use numpy.linspace for these cases." As recommended, I've switched this code to use numpy.linspace, which is guaranteed to produce the correct number of values.
* filter: Remove manual memory managementThomas Habets2020-07-058-35/+8
| | | | | | | | | | | | | | | | | | | | | Mostly manual work, followed by updating checksums. Note that there were (and still remain) a lot of default copy constructors and copy assignment operators in the codebase that are not safe. And they're even exported to Python (some removed in this commit). While it's perfectly possible to allow safe copies once raw pointers are removed, it seems like a performance trap waiting to happen. Hence I removed the fir_filter copy cons/assignment. Short script I used to update the header file hashes for pybind11: ``` a=polyphase_filterbank S=$(md5sum $(find -name "${a}.h") | awk '{print $1}') sed -i -r "s/(BINDTOOL_HEADER_FILE_HASH)[(].*[)]/\1($S)/" $(find -name "${a}_python.cc") ```
