Changes for version v2.014 - 2015-10-12

  • General Notes:
    • This is PDL-2.014 introducing full support for 64bit indexing operations using 64bit PDL_Indx data type.
    • PDL can now create and use piddles having more than 2**32 elements. Of particular use is that you can now use PDL::IO::FlexRaw to memory map piddles from files on disk which can allow for simplified processing and IO on extremely large data.
    • Due to the new PDL_Anyval type changes, existing PDL::PP modules may need to be updated to support the new PDL Core version 12 API. Authors, please see PDL::API for macros to ease the porting.
      • Users, be aware that some modules may not work until they are updated by their maintainers.
  • Highlights:
    • Implement PDL_Anyval data type as union to support 64bit indexing
      • This adds a union data type to add 64bit integer support to the original PDL-2.x types which assumed that double was capable of holding all the "lesser" types. With the PDL_Anyval type, we can correctly handle 64bit integer data types and avoid errors and loss of precision due to conversions to or from PDL_Double. Special thanks to kmx and zowie for their help to complete and debug this implementation.
    • Many fixes to the build process to make PDL more robust to build, test, and install. This takes advantage of new automated CI testing via Travis CI on the github site.
      • Thanks much to Ed and Zakariyya for their work to get this started and maintained. This CI testing makes this the best tested and best testing PDL release ever!
    • Various documentation clean-ups and work to improve on-line viewing at http://metacpan.org and others. (Thanks kmx and Derek!)
    • A new ipow() method haw been added with 64bit integer support. ipow() calculates the integer exponentiation of a value by successive multiplications. This allows one to avoid loss of significance in integer exponents. pow() converts the value to double and will always have <52bits precision.
    • nbadover and ngoodover now return indx type (PDL_Indx)
    • PDL now detects when your perl installation has been built with floating point longer than 8 bytes and gives a one time warning that precision will be lost converting from perl NV to PDL_Doubles. This warning is given on "use PDL;"
    • "use PDL" now includes "use PDL::IO::Storable" This avoids a hard to diagnose crash that can occur when a user tries using Storable without the necessary "use PDL::IO::Storable".
    • MANY sf.net bugs fixed:
      • 400 dataflow slice crash around 2**31 boundary 399 Small doc fixes 398 $pdl->hdr items are lost after $pdl->reshape 396 online docs for modules only work first time in PDL shells 395 ipow (integer exponentiation) support for 64bit index support 394 demo cartography fails 383 gcc/#gfortran 4.9.2 needs -lquadmath 378 where on dice of pdl bad results 376 PDL Segmentation fault working with Storable restored PDL 347 t/#pdl_from_string.t has a failure if BADVAL_NAN=1 346 ExtUtils::F77 dependency causing problems for CPAN install 343 longlong constructor and display lose digits due to... 340 orover of byte data returns long type
