+ TXR 177
+ 2017-06-07
+
+
+ Features
+
+ - FFI:
+ - bitfields:
+ - struct members may be bitfields, using 1, 2 or 4 byte storage cells.
+ - enums:
+ - enum types convert between sets of symbols denoting numeric values,
+ and FFI type int.
+ - align operator in type language:
+ - the alignment of types can be customized to achieve effects like
+ packed structures, or conformance with unusual alignment requirements.
+ - endian types:
+ - big and little endian versions of int16, uint16, ... int64, uint64,
+ float and double.
+ - FFI transparently handles conversion.
+ - new macros: alignof, offsetof, arraysize, elemsize, elemtype
+ - numeric values in type language such as array sizes are now
+ evaluated expressions.
+ - new val type for transparently passing raw Lisp values.
+ - Streams:
+ - New put-buf and fill-buf functions for I/O based on buf type.
+ - FFI-type-driven conversions to/from buffers combine with buf I/O,
+ allowing TXR to deal with binary data in files and over networks.
+ - Command Line:
+ - new *args-eff* variable provides access to transformed command
+ line arguments.
+ - "Hash bang" support rewritten, and now features a "hash bang null hack":
+ - Additional arguments to TXR may be encoded in a hash bang line
+ after a null byte.
+ - lib:
+ - mkstring's <char> argument now optional, defaulting to space.
+
+ Bugs
+
+ - FFI:
+ - lingering broken assumption that alignment of pointers is the same
+ as their size.
+ - GC integrity issue in carray and cptr objects.
+ - Another GC integrity issue affecting basic FFI types.
+ - fixed incorrectly coded exception throws affecting code which
+ misuses one of the four functions that connect FFI and buffers.
+ - slots named nil in a FFI struct are now culled when making the
+ corresponding Lisp struct type.
+ - fixed broken handling of return values on big-endian platorms,
+ related to a historic quirk in libffi.
+ - fixed some broken conversions and range checks affecting some
+ integer types.
+ - fixed broken get semantics for arrays of bchar.
+ - failure to null-terminate decoded string.
+ - fixed clockid-t type not being defined on platforms that do have
+ the corresponding clockid_t C type.
+ - Build system:
+ - "make tests" doesn't cache output of failed tests, so they are repeated
+ when re-invoked.
