2 gerd 1.1
3     [--- WORK IN PROGRESS --- DO NOT DISTRIBUTE ---]
4    
5     The CMUCL project is pleased to announce the release of CMUCL 19a.
6     This is a major release which contains numerous enhancements and
7     bugfixes from the 18e release.
8    
9     CMUCL is a free, high performance implementation of the Common Lisp
10     programming language which runs on most major Unix platforms. It
11     mainly conforms to the ANSI Common Lisp standard. CMUCL provides a
12     sophisticated native code compiler; a powerful foreign function
13     interface; an implementation of CLOS, the Common Lisp Object System,
14     which includes multimethods and a metaobject protocol; a source-level
15     debugger and code profiler; and an Emacs-like editor implemented in
16     Common Lisp. CMUCL is maintained by a team of volunteers collaborating
17     over the Internet, and is mostly in the public domain.
18    
19     New in this release:
20    
21     * Feature enhancements:
22 toy 1.50 - Stack overflow checking added for FreeBSD/x86, Linux/x86 and
23     Solaris. Code that makes the control stack overflow (for
24     example due to unbounded recursion) will lead to a
25     STORAGE-ERROR being signaled, instead of making CMUCL crash.
26 gerd 1.1 - LISP:FIND-CLASS and LISP:CLASS-OF now return CLOS classes. The
27 emarsden 1.21 symbols LISP:STANDARD-CLASS, LISP:BUILT-IN-CLASS, and
28 gerd 1.3 LISP:STRUCTURE-CLASS name CLOS classes. It is no longer
29 gerd 1.1 necessary to SHADOWING-IMPORT these from PCL when doing MOP
30     programming, and it fixes some non-compliances as well.
31 emarsden 1.29 - Package locks: a package whose EXT:PACKAGE-LOCK is enabled
32     non-NIL is protected against changes in its structure (list of
33     exported symbols, use-list etc). Symbols in a package whose
34     EXT:PACKAGE-DEFINITION-LOCK is enabled are protected against
35     redefinition.
36 gerd 1.2 - Weak hash tables have been added for x86 systems.
37 gerd 1.4 - Local functions are now named (FLET <name> ...) or
38     (LABELS <name> ...).
39 gerd 1.80 - Compiler checking control string and number of args to FORMAT,
40     ERROR and WARN.
41 gerd 1.27 - TRACE automatically using encapsulation when function-end
42     breakpoints cannot be used.
43 gerd 1.28 - INSPECT working on CLOS instances.
44 toy 1.50 - Callbacks from foreign code to Lisp. Implemented for x86 and
45     sparc.
46 gerd 1.31 - Functions like GETHASH that are used in the implementation of
47     TRACE can now be traced. See also
48     DEBUG:*TRACE-ENCAPSULATE-PACKAGE-NAMES*.
49 gerd 1.39 - New facility for encapsulating functions, FWRAPPERS;
50     see also the CMUCL User Manual.
51     - TRACE and PROFILE have been reimplemented using fwrappers,
52     with the effect of tracing and profiling now working more
53     nicely together.
54     - When a profiled function is redefined, it is re-profiled.
55 toy 1.50 - A basic implementation of simple-streams added. Some
56     functionality may be missing.
57 gerd 1.51 - UNIX:UNIX-LSEEK working with files > 2G on BSDs.
58 gerd 1.52 - Type declarations on local bindings of special variables no
59     longer being ignored.
60 gerd 1.61 - DISASSEMBLE disassembling closure/funcallable instance
61     functions.
62     - (SETF EXT:WEAK-POINTER-VALUE) has been added.
63 gerd 1.63 - CMUCL no longer entering an infinite loop when dumping
64     circular constant lists to fasl files.
65 gerd 1.68 - COMPILE-FILE-PATHNAME's BYTE-COMPILE keyword arg defaulting
66     to *BYTE-COMPILE-DEFAULT* like COMPILE-FILE.
67 toy 1.78 - Added VOPs for CHAR=, CHAR<, and CHAR> when the second arg is a
68     constant character.
69     - Added missing VOPs for Sparc for array refs with a constant
70     index.
71     - Lisp binary will also look at the PATH envvar to find out it's
72     own location which is used to find other needed files.
73 gerd 1.88 - Byte-compiled code being executed ca. 1/3 faster.
74 toy 1.81
75 gerd 1.1 * Numerous ANSI compliance fixes:
76 gerd 1.5 - Many bugs in CMUCL's type system detected by Paul Dietz'
77     ANSI test suite have been fixed.
78     - Non-keyword keyword names in lambda lists are now accepted.
79 gerd 1.6 - Condition slot initialization fixed for the case that two
80     or more slots have the same :INITARG.
81 gerd 1.7 - Initforms are now evaluated once only during condition slot
82     initialization.
83     - USE-VALUE, STORE-VALUE, CONTINUE behavior corrected in presence
84     of multiple restarts having the same name.
85     - RESTART-CASE's interaction with local macros fixed.
86     - Interaction of COMPUTE-RESTARTS and RESTART-CASE fixed in
87     presence of multiple restarts having the same name.
88 gerd 1.8 - Condition slot readers/writers are generic functions.
89 gerd 1.9 - &WHOLE, &REST, &BODY in macro lambda lists can be followed
90     by destructuring patterns. The previous behavior of &BODY
91     when followed by (<body> <declarations> <doc>) is available
92     through the new lambda-list keyword EXT:&PARSE-BODY.
93 gerd 1.10 - ELT now signals an error in safe code when used on lists
94     with an out-of-bounds index.
95     - Accessing arrays in compiled code with out-of-bounds indices
96     now signals a TYPE-ERROR.
97 gerd 1.11 - DECLARE no longer being a special operator.
98 gerd 1.16 - DEFINE-CONDITION accepts slot option :DOCUMENTATION.
99 gerd 1.18 - Behavior of (... &KEY &ALLOW-OTHER-KEYS) fixed for
100     DESTRUCTURING-BIND and macros.
101 gerd 1.19 - Stricter checking of keyword argument list in CLOS methods.
102 gerd 1.20 - &ENVIRONMENT variable bound bound before other vars, regardless
103     of where it appears in a lambda-list.
104 gerd 1.22 - VALUES types no longer accepting &KEY or &ALLOW-OTHER-KEYS.
105     - THE conforming to ANSI.
106 gerd 1.24 - SLOT-EXISTS-P can be used with conditions.

113     ANSI 7.6.5.
114 gerd 1.45 - CALL-NEXT-METHOD without arguments being called with original
115     arguments when method parameters are changed with SETQ.
116     - When CALL-NEXT-METHOD is called with arguments, an error is
117     signaled in safe code when the set of methods applicable to
118     CALL-NEXT-METHOD's arguments is different from the set of
119     methods applicable to the original method arguments.
120 gerd 1.46 - FIND-METHOD signaling an error when called with specializers
121     not corresponding to the number of required arguments of the
122     supplied generic function.
123 gerd 1.48 - TYPE-OF returning KEYWORD for keywords, STANDARD-CHAR for
124     standard characters, BOOLEAN for T, (INTEGER <N> <N>) for
125     integers N, non-list types for functions, and CLOS classes for
126     instances whose class doesn't have a proper name.
127 gerd 1.49 - Class precedence list of NULL not having SYMBOL before LIST,
128     precedence list of STANDARD-METHOD not having METHOD before
129     STANDARD-OBJECT.
130 gerd 1.55 - ADD-METHOD returning its first argument, the generic function.
131 gerd 1.54 - DEFCLASS redefining a class with the given name only if the
132     name is the proper name of an existing class.
133 gerd 1.57 - KEYWORD package no longer having nickname "".
134 gerd 1.60 - COMMON-LISP-USER package no longer having nickname USER.
135     - COMMON-LISP package no longer having nickname LISP; LISP
136     and COMMON-LISP are now separate packages.
137 gerd 1.58 - SLOT-VALUE, (SETF SLOT-VALUE), SLOT-BOUNDP, SLOT-MAKUNBOUND

141 gerd 1.66 - First arg of CERROR may be a function.
142 gerd 1.67 - Lambda-lists of the form (X . Y) in DESTRUCTURING-BIND and macros
143     are now equivalent to (X &REST Y).
144 gerd 1.69 - LAST, BUTLAST, NBUTLAST accepting bignum counts.

148 gerd 1.89 - Numerous LOOP fixes.
149 gerd 1.1
150     * Numerous bugfixes:
151 gerd 1.12 - NSET-EXCLUSIVE-OR returns the same results as SET-EXCLUSIVE-OR
152     wrt to duplicate elements.
153 gerd 1.11 - Forms like (MULTIPLE-VALUE-BIND 'LIST) no longer trapping
154     an internal compiler error when compiled.
155 gerd 1.16 - PARSE-INTEGER signaling PARSE-ERROR.
156     - Compiler eliminating some type checks in safe code.
157 gerd 1.41 - Byte-compiler and -interpreter not handling C:&MORE.
158     - Some TYPE-ERRORs being signaled with unbound slots, which
159     made them undisplayable.
160 gerd 1.62 - Structure predicates no longer signaling an error when applied
161     to obsolete instances.
162 gerd 1.64 - A DEFTRANSFORM for array bounds checking had an off-by-1 error.
163 toy 1.78 - Compiler was not properly deriving the type of FTRUNCATE in all
164     cases.
165     - Fixed error wherein certain uses of 2 arg ATAN caused a
166     compiler error on x86.
167 gerd 1.84 - Compiler wrongly signaling a type error in VOLATILE-INFO-LOOKUP or
168     COMPACT-INFO-LOOKUP for hash values equal to MOST-POSITIVE-FIXNUM.
169 gerd 1.85 - FFLOOR and FCEILING return types sometimes being inferred as
170     being the nil type.
171 gerd 1.90 - PARSE-TIME accepting GMT offsets with a leading plus sign.
172 gerd 1.91 - UNIX-MMAP not accepting a null fd, preventing anonymous
173     mappings.
174     - SIGPROF having the wrong value on GNU/Linux.
175 gerd 1.1
176     * Other changes:
177 emarsden 1.72 - CREATE-REQUEST-SERVER has an additional :reuse-address keyword
178     argument.
179 emarsden 1.21 - Removed obsolete alias from MAKE-VECTOR to MAKE-ARRAY
180 emarsden 1.44 - the signature of *COMPILER-NOTIFICATION-FUNCTION* has changed;
181     it now has an extra argument that describes the nature of the
182     error or warning.
183 toy 1.78 - File versioning occurs when the version component is :NEWEST,
184 toy 1.56 and Emacs style file versions are created: foo.bar.~N~, where
185     the larger N is newer. foo.bar is the newest version.
186     - Converting namestrings to pathnames now get a version component
187     of NIL instead of :NEWEST.
188 toy 1.78 - *DEFAULT-PATHNAME-DEFAULTS* has a version component of
189     :UNSPECIFIC instead of :NEWEST so versioning is disabled by
190 toy 1.56 default to preserve current behavior. Set the version to
191 toy 1.78 :NEWEST to create versions.
192 gerd 1.73 - LDB backtrace on x86.
193 gerd 1.82 - DYNAMIC-EXTENT support on x86 and sparc. Stack-allocation can
194     be controlled by the setting of
195     EXT:*TRUST-DYNAMIC-EXTENT-DECLARATIONS*. See also the CMU User
196     Manual. Be warned that all bets are off if a stack-allocated
197     object or parts of it escape; CMUCL might crash or format your
198     hard disk.
199     - Generational GC (gencgc) available for Sparc/Solaris on an
200 toy 1.81 experimental basis. Despite the name and feature, it is not
201     conservative.
202 gerd 1.1
203     * Numerous improvements to the PCL implementation of CLOS:
204     - Gerd's PCL has been added, which fixes numerous bugs and ANSI/
205     AMOP non-compliances, and adds various new optimizations (also
206     see the CMU User Manual).
207 gerd 1.2 - PCL's class hierarchy has been changed to conform to AMOP, for
208     instance, GENERIC-FUNCTION is now a subclass of
209     STANDARD-OBJECT.
210 gerd 1.4 - ENSURE-CLASS-USING-CLASS's argument list has been changed
211     to conform to AMOP.
212 gerd 1.5 - COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes a slot name as
213     argument, for AMOP compliance.
214 gerd 1.9 - SUBTYPEP works in presence of forward-referenced classes.
215 gerd 1.13 - Accessing slots of specialized parameters in (SETF
216     SLOT-VALUE-USING-CLASS) methods works.
217 gerd 1.14 - DIRECT-SLOT-DEFINITION-CLASS and EFFECTIVE-SLOT-DEFINITION-CLASS
218     AMOP compliant.
219 gerd 1.15 - ALLOCATE-INSTANCE working with structures defined with DEFSTRUCT.
220 gerd 1.23 - With (DEFGENERIC FOO (&REST X &KEY)) (DEFMETHOD FOO (&REST X) X),
221     (FOO 1) now signals an error.
222 gerd 1.33 - Methods with &OPTIONAL arguments detecting too many args.
223 gerd 1.35 - DEFMETHOD and DEFGENERIC detecting doubled lambda variables.
224 gerd 1.34 - DEFGENERIC :ARGUMENT-PRECEDENCE-ORDER option checking.
225     - SLOT-VALUE, (SETF SLOT-VALUE), SLOT-BOUNDP working with conditions.
226 gerd 1.36 - (SETF SLOT-VALUE) working on read-only structure slots like
227     in other implementations.
228 gerd 1.38 - The declaration identifiers SLOTS, AUTO-COMPILE,
229     NOT-AUTO-COMPILE have been moved from PCL to EXT.
230 gerd 1.42 - Support for inlineing methods in effective methods; see the
231     CMU User Manual.
232 gerd 1.47 - Wrong results could be returned from generic functions when
233     all methods returned constant values, and some methods were
234     qualified, or the generic function didn't use the standard
235     method combination.
236 gerd 1.59 - For standard method combination and method combinations defined
237     with the short form of DEFINE-METHOD-COMBINATION: If there are
238     no applicable primary methods when a generic function is
239     called, the generic function PCL:NO-PRIMARY-METHOD is called.
240     The default method of this generic function signals a
241     continuable error of type PCL:NO-PRIMARY-METHOD-ERROR.
242 gerd 1.74 - Effective methods are no longer precomputed at method load
243 gerd 1.82 time, if the generic function has more than
244     PCL:*MAX-EMF-PRECOMPUTATION-METHODS* methods (default 100).
245     - The loading of methods with invalid qualifiers no longer
246     signals an error, for standard's conformance. Instead, a
247     warning is printed at method load time. An error is
248     signaled if the generic function is called with arguments such
249     that the method is used.
250 gerd 1.83 - Redefining a generic function with a different method
251     combination now recomputes effective methods.
252 gerd 1.1
253     * Improvements to Hemlock, the Emacs-like editor:
254    
255     * Changes to rebuilding procedure:
256    
257     * Deprecated features:
258 gerd 1.39 - EXT:ENCAPSULATE and associated functions; use fwrappers instead.
259 gerd 1.1
260     This release is not binary compatible with code compiled using CMUCL
261     18e; you will need to recompile FASL files.
262    
263     See <URL:http://www.cons.org/cmucl/> for download information,
264     guidelines on reporting bugs, and mailing list details.
265    
266    
267     We hope you enjoy using this release of CMUCL!
