Changes since 4.7.0:
4.7.0.6
The stability (-st) branch is now the official branch for point
releases, so the -st suffix has been retired.
- Security fixes
- on 64-bit machines the "random" procedure no longer truncates result
values (which caused very nonrandom results for very large values).
Note that random shouldn't be used for security-critical code.
- Core libraries
- tcp-connect now closes socket on connection timeout
[thanks to Jorg Wittenberger].
- Ensure srfi-13 string comparison returns a boolean, fix bugs in
xsubstring and string-xcopy!, and add a test suite.
- Fix off-by-one error in pending finalizer code which could lead to crash.
- Exceptions signalled by code that executes in finalizers will now
be caught and do not propagate upwards into arbitrary user code.
4.7.0.5-st
- Build system
- LLVM gcc and clang can now be used to compile the system. Previously,
building with LLVM produced binaries that would hang and use 100% CPU.
Fixes compatibility with OS X 10.6 and later.
- Core libraries
- symbols with a single-char print-name were not always properly escaped
when printed readably (#772)
4.7.0.4-st
- Core libraries
- "with-input-from-file", "with-output-to-file", "with-input-from-pipe" and
"with-output-to-pipe" now properly restore the standard input/output
ports in case the body thunk escapes
- Build system
- Fixes for port tests
- C_TARGET_INCLUDE_HOME fix for cygwin
4.7.0.3-st
- Core libraries
- fixed bug in reading of octal escape in string literal
- Compiler
- fixed erroneous optimization of toplevel assignments in the presence
of conditionals (found by Paul Colby and Mario Domenench Goulart).
For example, this had printed "undefined" and now prints "good":
(define A #t)
(define B 'undefined)
(if A
(set! B 'good)
(set! B 'bad))
(print B)
4.7.0.2-st
- Core libraries
- port-procedures now check correctly for argument-ports being open
(thanks to Peter Bex)
- fixed irregex overlapping charsets problem (#636)
- Runtime system
- fixed handling of "inf" floating-point predicate for Solaris
(thanks to Claude Marinier)
- Core tools
- "chicken-profile"
- fixed broken percentage calculation (thanks to "megane")
- Compiler
- the "-uses" option handles whitespace in unit lists given on the
command line (thanks to Santosh Rajan)
4.7.0.1-st
- Build system
- The default target library name for an installation configured for cross-
compilation is now "libchicken" and independent on any particular
setting of PROGRAM_PREFIX/PROGRAM_SUFFIX (thanks to Otavio Salvador)
- Compiler
- Fixed incorrect optimization rules for some fp-rounding and fixnum operators
- Unused arguments in callback wrappers were incorrectly optimized away (#584)
- Core libraries
- Fixed bugs in "make-pathname" and "normalize-pathname" (thanks to Jim Ursetto)
- The reader is now more consistent when parsing symbol- and keyword names
that are fully or partially escaped (thanks to Kon Lovett)
- Fixed a bug in the Windows implementation of "file-type" (thanks to
Jim Ursetto)
- Fixed a bug in the implementation of "current-milliseconds" that could
result in integer-overflow
- Fixed an incorrect type-check in "list-ref" (thanks to Sven Hartrumpf)
- Fixed bug in "string->number" that caused out-of-range characters to
be accepted for base > 10 (thanks to Jim Ursetto)
- Foreign function interface
- "int32" was not properly detected as a valid foreign type (thanks
to Jim Ursetto)
- Syntax expander
- Fixed a bug in the processing of extended lambda-lists (thanks to Peter Bex)
