Revision 1.44 - (hide annotations)
Mon Jun 2 16:29:24 2003 UTC (10 years, 10 months ago) by emarsden
Branch: MAIN
Changes since 1.43: +4 -0 lines
File MIME type: text/plain
Change to the compiler's error/note reporting:

   - an extra optional argument to COMPILER-NOTIFICATION makes it
     possible to pass text describing the error/note to
     *COMPILER-NOTIFICATION-FUNCTION*.

   - functions for *COMPILER-NOTIFICATION-FUNCTION* have an extra
     second argument which describes the error/note

   - modify the eval-server functionality in Hemlock in consequence

This backwards-incompatible change makes the
*COMPILER-NOTIFICATION-FUNCTION* facility considerably more useful,
since the description of the error (which was previously not passed to
the notification-function) is very useful when reporting an error.


Compile-time effect of DEFCONSTANT: instead of discarding the
documentation string, add it to the info database.
1 gerd 1.1 ========================== C M U C L 18 e =============================

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     - Stack overflow checking added for FreeBSD/x86 and Linux/x86.
23 emarsden 1.29 Code that makes the control stack overflow (for example due to
24     unbounded recursion) will lead to a STORAGE-ERROR being
25     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 1.17 - Compiler checking control string and number of args to FORMAT.
40 gerd 1.27 - TRACE automatically using encapsulation when function-end
41     breakpoints cannot be used.
42 gerd 1.28 - INSPECT working on CLOS instances.
43 toy 1.30 - Callbacks from foreign code to Lisp.
44 gerd 1.31 - Functions like GETHASH that are used in the implementation of
45     TRACE can now be traced. See also
46     DEBUG:*TRACE-ENCAPSULATE-PACKAGE-NAMES*.
47 gerd 1.39 - New facility for encapsulating functions, FWRAPPERS;
48     see also the CMUCL User Manual.
49     - TRACE and PROFILE have been reimplemented using fwrappers,
50     with the effect of tracing and profiling now working more
51     nicely together.
52     - When a profiled function is redefined, it is re-profiled.
53 gerd 1.1
54     * Numerous ANSI compliance fixes:
55 gerd 1.5 - Many bugs in CMUCL's type system detected by Paul Dietz'
56     ANSI test suite have been fixed.
57     - Non-keyword keyword names in lambda lists are now accepted.
58 gerd 1.6 - Condition slot initialization fixed for the case that two
59     or more slots have the same :INITARG.
60 gerd 1.7 - Initforms are now evaluated once only during condition slot
61     initialization.
62     - USE-VALUE, STORE-VALUE, CONTINUE behavior corrected in presence
63     of multiple restarts having the same name.
64     - RESTART-CASE's interaction with local macros fixed.
65     - Interaction of COMPUTE-RESTARTS and RESTART-CASE fixed in
66     presence of multiple restarts having the same name.
67 gerd 1.8 - Condition slot readers/writers are generic functions.
68 gerd 1.9 - &WHOLE, &REST, &BODY in macro lambda lists can be followed
69     by destructuring patterns. The previous behavior of &BODY
70     when followed by (<body> <declarations> <doc>) is available
71     through the new lambda-list keyword EXT:&PARSE-BODY.
72 gerd 1.10 - ELT now signals an error in safe code when used on lists
73     with an out-of-bounds index.
74     - Accessing arrays in compiled code with out-of-bounds indices
75     now signals a TYPE-ERROR.
76 gerd 1.11 - DECLARE no longer being a special operator.
77 gerd 1.16 - DEFINE-CONDITION accepts slot option :DOCUMENTATION.
78 gerd 1.18 - Behavior of (... &KEY &ALLOW-OTHER-KEYS) fixed for
79     DESTRUCTURING-BIND and macros.
80 gerd 1.19 - Stricter checking of keyword argument list in CLOS methods.
81 gerd 1.20 - &ENVIRONMENT variable bound bound before other vars, regardless
82     of where it appears in a lambda-list.
83 gerd 1.22 - VALUES types no longer accepting &KEY or &ALLOW-OTHER-KEYS.
84     - THE conforming to ANSI.
85 gerd 1.24 - SLOT-EXISTS-P can be used with conditions.
86 gerd 1.32 - REMOVE-METHOD always returning the generic function passed to it.
87     - Standard methods for STANDARD-OBJECT and STRUCTURE-OBJECT
88     defined on MAKE-LOAD-FORM.
89     - Compliant MAKE-LOAD-FORM-SAVING-SLOTS.
90 gerd 1.37 - DEFSTRUCT recording slot-names as specified by users.
91 gerd 1.40 - Generic function call keyword argument checking according to
92     ANSI 7.6.5.
93 gerd 1.1
94     * Numerous bugfixes:
95 gerd 1.12 - NSET-EXCLUSIVE-OR returns the same results as SET-EXCLUSIVE-OR
96     wrt to duplicate elements.
97 gerd 1.11 - Forms like (MULTIPLE-VALUE-BIND 'LIST) no longer trapping
98     an internal compiler error when compiled.
99 gerd 1.16 - PARSE-INTEGER signaling PARSE-ERROR.
100     - Compiler eliminating some type checks in safe code.
101 gerd 1.41 - Byte-compiler and -interpreter not handling C:&MORE.
102     - Some TYPE-ERRORs being signaled with unbound slots, which
103     made them undisplayable.
104 gerd 1.1
105     * Other changes:
106 emarsden 1.21 - Removed obsolete alias from MAKE-VECTOR to MAKE-ARRAY
107 emarsden 1.44 - the signature of *COMPILER-NOTIFICATION-FUNCTION* has changed;
108     it now has an extra argument that describes the nature of the
109     error or warning.
110    
111 gerd 1.1
112     * Numerous improvements to the PCL implementation of CLOS:
113     - Gerd's PCL has been added, which fixes numerous bugs and ANSI/
114     AMOP non-compliances, and adds various new optimizations (also
115     see the CMU User Manual).
116 gerd 1.2 - PCL's class hierarchy has been changed to conform to AMOP, for
117     instance, GENERIC-FUNCTION is now a subclass of
118     STANDARD-OBJECT.
119 gerd 1.4 - ENSURE-CLASS-USING-CLASS's argument list has been changed
120     to conform to AMOP.
121 gerd 1.5 - COMPUTE-EFFECTIVE-SLOT-DEFINITION now takes a slot name as
122     argument, for AMOP compliance.
123 gerd 1.9 - SUBTYPEP works in presence of forward-referenced classes.

127     AMOP compliant.
128 gerd 1.15 - ALLOCATE-INSTANCE working with structures defined with DEFSTRUCT.
129 gerd 1.23 - With (DEFGENERIC FOO (&REST X &KEY)) (DEFMETHOD FOO (&REST X) X),
130     (FOO 1) now signals an error.

132 gerd 1.35 - DEFMETHOD and DEFGENERIC detecting doubled lambda variables.
133 gerd 1.34 - DEFGENERIC :ARGUMENT-PRECEDENCE-ORDER option checking.
134     - SLOT-VALUE, (SETF SLOT-VALUE), SLOT-BOUNDP working with conditions.
135 gerd 1.36 - (SETF SLOT-VALUE) working on read-only structure slots like
136     in other implementations.
137 gerd 1.38 - The declaration identifiers SLOTS, AUTO-COMPILE,
138     NOT-AUTO-COMPILE have been moved from PCL to EXT.
139 gerd 1.42 - Support for inlineing methods in effective methods; see the
140     CMU User Manual.
141 gerd 1.43 - CALL-NEXT-METHOD always being called with original arguments.
142 gerd 1.1
143     * Improvements to Hemlock, the Emacs-like editor:
144    
145     * Changes to rebuilding procedure:
146    
147     * Deprecated features:
148 gerd 1.39 - EXT:ENCAPSULATE and associated functions; use fwrappers instead.
149 gerd 1.1
150     This release is not binary compatible with code compiled using CMUCL
151     18e; you will need to recompile FASL files.
152    
153     See <URL:http://www.cons.org/cmucl/> for download information,
154     guidelines on reporting bugs, and mailing list details.
