Highlights of changes:
- Support for much larger range of sample rates. Outside of the range 32767 to 1/32767 integer sample rates are approximated whenever possible.
- Rewrite of all decoding and encoding routines to replace those used from qlib2, now the entire project is LGPL licensed.
ChangeLog since 2.17:
- Remove limitation on sample rate before calling ms_genfactmult() in the normal path of packing records. Previously generating the factor and multiplier was not attempted for rates higher than 32,767. - ms_genfactmult() now support a much larger range of integer sample rates and periods. - ms_genfactmult() now sets the factor and multiplier using the SECONDS/SAMPLE notation for sample rates less than 1.0 to retain precision for low rates. - ms_genfactmult() now assumes the specified rate is a sample period in seconds if the samprate value is negative. - Add ms_rsqrt64() as a general use reciprocal sqrt for doubles. - Use memcpy() instead of assignment when unpacking float32 and float64 samples to avoid problems with NaN's. Thanks Lion Krischer. - Add test for reading records without Blockette 1000. - Reformat all source code using included clang-format profile. - A more elegant sanity check for output length in packing by mbyt. - Improvements for test suite, more consistency. - Remove msr_decode_steim? from libmseed.def, they are internal. - Add sanity to length check before memset calls in packing functions. - Check for environment variables ENCODE_DEBUG and DECODE_DEBUG and set debugging output, at this point it is Steim frame details and differences being encoded/decoded. - Fix padding in steim encoding routines. - Remove unneeded output buffer checks in steim decoding routines. - Replace data sample packing and unpacking routines from qlib2 with new routines developed from scratch. All code is now LGPL licensed. - Add test suite with tests for encoding, decoding, parsing, etc. - Update licensing to GNU-LGPL version 3 and include (L)GPL licenses in LICENSE.txt. - Define needed C99 int types for MSVC 2012 or earlier. Previously this was only done for versions earlier than MSVC 2010.
