  • Options:
  • This was a bug in CsOptions; the last argument was missed being read (issue #296)
  • As command-line options expression-opt and no-expression-opt do nothing in Csound6 a warning is printed.
  • Modified Opcodes and Gens:

  • SYSTEM LEVEL CHANGES:
  • System changes:

  • the way of rounding a table number to an integer was changed and is now more as expected.
  • there is a new possible section in a csd file called which is like csFileB but with unencoded text.
  • UDO compilation now uses the type system. This means that UDOs now allow any array type to be used.
  • Improved orchestra parsing speeds with better algorithms
  • Internal changes:
  • The whole system has been checked by the Coverity static checker which identified a number of (mainly minor) problems. These have been reviewed and checked. In particular better use of printing and string copying should prevent overflows.
  • The type and variable system has been extensively rewritten; this allows better array and UDO support.
  • Alignment of variables got right in all cases
  • array copying is now using the type system to copy values; fixes issues with copying string arrays, f-sigs, etc.
  • Always reset Csound when stopping to ensure state is clean; was not being reset when there was a compile error, so that next successful run would start with an invalid Csound engine (issue #305)
  • API:
  • All opcodes etc now use the API memory allocation operations, so it is possible to replace the whole memory allocator.
  • Added csoundCompileCsd to API and associated new compilecsd opcode
  • Protected csoundGetStringChannel against null and short strings and added a check for string size
  • A number of API functions have had char* changed to const char* which reflect the usage
