It +mainly conforms to the ANSI Common Lisp standard. CMUCL provides a +sophisticated native code compiler; a powerful foreign function +interface; an implementation of CLOS, the Common Lisp Object System, +which includes multi-methods and a meta-object protocol; a source-level +debugger and code profiler; and an Emacs-like editor implemented in +Common Lisp. CMUCL is maintained by a team of volunteers collaborating +over the Internet, and is mostly in the public domain. + +New in this release: + + * Known issues: + - Executable images on Linux may not be able to be created on some + versions of Linux. The problem is in GNU ld which doesn't + allocate enough phdrs to create an executable. + + * Feature enhancements: + - Read operations using an external format of utf8 are now much + faster. Some simple tests on Linux shows that read-line now + only takes 40% as much time. Sparc shows 60% as much time. + - ASCII external format added. + - Support for static arrays added. These are allocated in foreign + space and are never moved by GC. When the arrays are no longer + referenced, they are properly freed. To create an array, use + new the :ALLOCATION :MALLOC parameter to MAKE-ARRAY. Currently, + only arrays of character; 8, 16, and 32-bit integers (signed and + unsigned); single and double floats; and complex single and + double floats are supported. + - FROUND and FTRUNCATE are much faster for single and double float + numbers. This is not currently available for x87 (due to + potential roundoff errors), but is available everywhere else. + - Support for internationalization/localization added. Messages + from CMUCL can be translated, but currently only a few messages + in Korean are translated. For fun, there is a full Pig Latin + translation (done by machine). + - Source information (file) for defstructs and deftypes is now + provided. DESCRIBE will now print out the name of the file + where the defstruct/deftype was defined. + - ASDF2 and MK-DEFSYS have been added as contrib modules. Use + (require 'asdf) or (require 'defsystem) to load these, + respectively. + - The previous cmu-contrib module no longer exists. Just use + (require 'module-name) to load the desired contrib module. + - A new switch, -help, has been added. These print out brief + summary of the available command line switches and then exits. + You may also use --help, which is an alias for -help. + - Error handling has been added to external formats. Previously, + all external formats would silently replace bad encodings with a + suitable replacement character. Now, the user can specify how + the errors are handled by using the :DECODING-ERROR and + :ENCODING-ERROR parameters to OPEN. The default is the previous + behavior. + + For decoding-error, a character, symbol, or function + can be given. If a character, then that character is used as + the replacement character. For a symbol or function, it must be + a function of 3 arguments: a message string, the offending + octet (or nil), and the number of octets read in the encoding. + If the function returns, it must be the codepoint of the desired + replacement. + + For encoding-error, a character, symbol, or function can be + given. If a character, then that character is used as the + replacement character. For a symbol or function, it must be a + function of 2 arguments: a message string and the offending + codepoint. If the function returns, it must be the codepoint of + the desired replacement. + - Add EXT:LIST-ALL-EXTERNAL-FORMATS to list all known external + formats and their aliases. + - ADD EXT:DESCRIBE-EXTERNAL-FORMAT to print a description of the + specified external format. To support this, the macros + DEFINE-EXTERNAL-FORMAT and DEFINE-COMPOSING-EXTERNAL-FORMAT have + changed. + - The sparc port now supports the :executable feature. + - The Mac OS X port now support the :executable feature. + + * ANSI compliance fixes: + - COMPILE will update the macro-function if the specified name + names a macro. (Previously, the fdefinition of the name was + set.) + - WITH-STANDARD-IO-SYNTAX uses the standard pprint dispatch table + now instead of the current table. + - PRINC-TO-STRING binds *PRINT-READABLY* to NIL as required. + Previously, it used the current value of *PRINT-READABLY*. + - DEFCLASS signals an error if the class name already names a + DECLARATION. + - The :METHOD-CLASS argument to ENSURE-GENERIC-FUNCTION can be a + class object as well as a name. + - Recognize but ignore the :DECLARE argument to + ENSURE-GENERIC-FUNCTION. + - Default documentation for short form of + DEFINE-METHOD-COMBINATION is NIL, not "". + - DEFINE-COMPILER-MACRO no longer sets the wrong block name for + SETF functions. We also check that the name is a valid function + name; an error is signalled if it's invalid. + - DELETE-FILE, ENSURE-DIRECTORIES-EXIST, FILE-AUTHOR, + FILE-WRITE-DATE, and OPEN now merge the given pathname with + *DEFAULT-PATHNAME-DEFAULTS* as required by CLHS sec 19.2.3. + + * Bugfixes: + - On Unicode builds, printing of '|\|| and '|`| was incorrect + because no escapes were printed. This is fixed now. + - Fixed issue with SSE2 support. The vops for complex +/- float + would add random junk to the imaginary part of the result. + - UNIX-SYSINFO was broken for Unicode builds, which affected + MACHINE-TYPE and MACHINE-VERSION. + - Type predicates for double-double float and complex + double-double float arrays are now done inline. + - UNIX:UNIX-EXECVE was not converting Lisp strings to C strings on + Unicode builds. + - When continuing from the INTEXP-LIMIT-ERROR condition (for + raising an integer to a large integer power) and setting a new + limit, the limit was set to the power. We really wanted the + absolute value of the power to used as the new limit. + - FILE-POSITION was returning incorrect values for file streams on + Unicode builds. This is fixed now. + - The error-output and trace-file files for COMPILE-FILE are now + opened using the same external format as specified in + COMPILE-FILE. Previously, they were opened using the default + external format. This meant that these files could lose + information if the default format could not represent the + characters in the source file. + - Handling of source files in the debugger is better now for + Unicode builds. The source files are opened using the same + format as used to compile them. Previously, the default format + was used, which would be wrong if the file is in a different + format. + - CMUCL no longer segfaults on Linux when running on a kernel + without COMPAT_BRK. CMUCL will set the personality + appropriately and re-exec itself. + - GET-MACRO-CHARACTER would return the wrong second value because + *READTABLE* was always being used instead of the specified + readtable. + - COMPILE-FILE was generating an error when compiling COMPILE + forms. This is fixed. + - A critical bug in SSE2 support has been fixed. Multiplying a + complex single-float by a single-float produced the wrong + result. + - Fix issue where CMUCL does not correctly handle FLETs in + DEFMETHOD bodies which use the same name as that of the generic + function. The generic function was called instead of the local + function. + - CMUCL would fail to compile external formats if *readtable* was + not the standard readtable. This is fixed by using the standard + I/O syntax when compiling the external format. + - The debugger help message is updated to reflect the actual + options for L and PP commands. Help for the DESCRIBE command + has been added. + - CMUCL now signals a cerror when attempting to redefine a slot + accessor via DEFUN or COMPILE. If continued, the accessor is + redefined, and CMUCL assumes the new definition is usable as a + slot accessor. Previously, CMUCL would print a warning and + undefine the structure. + - An issue with SSE2 and GC hooks has been fixed. This shows up + when doing arithmetic with GC hooks that use the SSE registers. + The SSE state is saved along with the x87 state. + - GCD of positive integers no longer returns a negative result for + certain arguments. + - CMUCL no longer crashes on Mac OS X if the dynamic space size is + too large. This was caused by an erroneous value for the + maximum dynamic space size. + - When printing out argument values in the debugger and also + during TRACE, the incorrect values were returned for the SSE2 + core. This was caused by using the x87 values instead of the + sse2 values in the sigcontext. This is fixed now. + - A critical bug in the fast Unicode stream buffering routine has + been fixed. This bug manifests itself by causing valid + sequences to be incorrectly decoded, resulting in a replacement + character. + - UTF-8 correctly catches overlong sequences now. Previously, + overlong sequences were missed. + - When UTF-8 decoder encounters an overlong sequence, a surrogate + code point, or a too-large codepoint, the entire sequence is + converted to the replacement character. Previously, all of the + octets except the first were put back, and the data read again. + - Some GC improvements for sparc and ppc. (Changes for ppc + untested). GC could incorrectly move the PC and other + registers, causing a segfault. + - A bug inadvertently introduced in the 2010-04 non-unicode + snapshot has been fixed. The bug prevented the non-unicode + versions of CMUCL from loading the external format aliases + file. + - With SSE2, the imaginary part of a (complex single-float) is now + returned correctly. + - The method used to create executable images for Linux has been + cleaned up and should be far more robust against different + versions of the OS. The same is true on sparc as well as Mac OS + X. + - It is possible to hash NaNs now. (Previously gave an invalid + operation exception.) + - For SSE2 builds, = no longer signals an error if one operand is + NaN. This matches what happens for x87. + - For SSE2 builds, SIGCONTEXT-FLOAT-REGISTER returned the wrong + value for single-floats. Easily noticed when tracing a + function with single-float arguments. + - The table for Unicode 1.0 names was constructed incorrectly. + Thus, UNICODE-1.0-NAME would return the wrong names for many + (all?) codepoints. + + * Trac Tickets: + #33: get-dispatch-macro-character doesn't signal errors in + compiled code + Fixed. + #22: sun4_solaris_sunc config uses gcc to build motif + This is fixed. If Sun C is used to build lisp, it is also used + to build motifd. + #39: non-standard lexical syntax + The reader macros are no longer installed by default. + #36: file-position broken for utf16 and utf32. + FILE-POSITION returns the correct value for UTF16 and UTF32 when + there is a BOM in the file. + + * Other changes: + - :freebsd4 is no longer a *feature* + - Added UNIX-GETENV, UNIX-SETENV, UNIX-PUTENV, and UNIX-UNSETENV, + in the UNIX package to allow access to these C functions. + - OCTETS-TO-STRING has changed. + o The output string is no longer automatically extended. + o Parameters can be given to specify the start and end of the + octet array and for the start and end of the string. + (These all default to the beginning and end of the arrays.) + - UNIX-GETRLIMIT added for solaris and darwin/x86. + - TRANSLATE-PATHNAMES now creates the resulting path to be an + absolute or relative path according to whether the TO pathname + is absolute or relative. Previously, the result was taken from + the SOURCE pathname, except if TO were absolute, in which case + the result was absolute. + - Add MAC as an alias to the CR composing external format. + + * Improvements to the PCL implementation of CLOS: + + * Changes to building procedure: + +This release is not binary compatible with code compiled using CMUCL +20a; you will need to recompile FASL files. + +See <URL:http://www.cons.org/cmucl/> for download information, +guidelines on reporting bugs, and mailing list details. + + +We hope you enjoy using this release of CMUCL! +
