+ TXR 176
+ 2017-05-21
+
+
+ Features
+
+ FFI:
+ - New tagged variant of cptr type, for improved safety.
+ - New carray type for handling arrays of unknown size,
+ where FFI's automatic memory handling isn't of help.
+ - deffi-type is just called typedef
+ - New ffi macro providing a shorthand for ffi-type-compile.
+ - Variable length arrays that are null-terminated (zarray <type>)
+ now have useful semantics: the type can extract an arbitrarily
+ long null-terminated array from foreign memory.
+ - Previously undocumented ffi-call function is now documented,
+ and has undergone an API change.
+ - deffi macro now generates Lisp functions with fixed number of
+ arguments, so a mismatch in number of arguments is caught
+ at the wrapper level, rather than down inside ffi-call.
+ - New deffi-var macro for defining a Lisp variable connected
+ to a foreign variable.
+ Awk macro:
+ - New (again) operator for repeating all the rules against
+ the same record.
+ Filesystem:
+ - New functions dir-name, base-name and variable path-sep-chars.
+ - New function realpath, wrapper for the POSIX one.
+
+ Bugs
+
+ - fixed corrupt line numbers being reported in some
+ situations, like unbound variables inside quasi-word-list literals.
+ - FFI:
+ - fixed broken in semantics of buf type.
+ - fixed broken alignment of basic types leading to wrong
+ struct layouts.
+ - nil value now handled by FFI buf type, mapped to null pointer.
+ - A ffi call now releases up temporary local memory when an
+ exception occurs in the argument preparation phase.
+ - A ffi callback similarly releases any temporary memory
+ allocated during the preparation of the return value, if
+ the preparation terminates due to an exception.
+ - Defense in the type system against incomplete (i.e. zero sized)
+ types being passed or returned by value, or used as array
+ elements or struct slots.
+ - Fixed wrong documentation about variable-length arrays corresponding
+ to pointers.
+ - FFI calls are now checked for proper number of arguments.
