Changed the level of rigor from FFTW_ESTIMATE to FFTW_MEASURE in order to resolve an issue where the FFTW library would sometime make a bad choice about the FFT algorithm to use. Added support for Wisdom files so that the FFTW library does not have to spend time picking the algorithm.

If the screen height is set to 425 or less pixels, then when the CW keyboard is opened, the sbitx application crashes. This occurs because the calculated screen height of the waterfall becomes a negative number. That height is used in a malloc() call near line 1523 in sbitx_gtk.c Obviously the malloc() call does not work well with a negative number, so it fails, and sbitx exits. This change prevents the waterfall area from having a height less than 0, which in turn prevents the malloc() call from failing.

As your commit history shows and as I have verified, all that is needed relative to the current HEAD of main is the last commit ( a577fd1 ). IMO the other stuff may cause trouble later. Ideally we'd have a PR with just one commit. |
