9  *  A functioning (A)MOP implementation through the hard work of Rudi
10     Schlatte (@rudi)
11
12  *  The implementation can be used across many more Quicklisp systems
13     through a process of extensive testing.  Thanks @xach!
14
15     Nota bene: all of the following systems need patches to work as
16     of the 2012-10-13 Quicklisp.  All patches have been accepted in
17     at least an initial form by the upstream maintainers.
18
19     ** CLOSER-MOP
20        Quite possible with local patches
21     ** CFFI
22       Needs patches to 2012-10-13 Quicklisp.  [!!?]
23       *** Dynamic interfaces idempotent across process -- no more reloading
24     ** HUNCHENTOOT
25       *** some bugs with underlying streams to be fixed in abcl-1.2-dev
26     ** CXML
27        Basic XML parsing works.  XPath still borked. [???]     
28  *  Java 5 bytecode Compiler
29
30     The internal Lisp-to-Java bytecode compiler has been hardened by
31     regression testing across Quicklisp libraries. 
32
33     **  Extensive interpreter/compiler bug fixes due to access to cl-test-suite [???] @antov
34     ** large objects (?!?)
35
36  *  The facility to construct runtime classes via JNEW-RUNTIME-CLASS (@astalla)
37
38    Pretty close to full coverage of primtives for creating synthethic
39    java classes at runtime.  Easy to extend with your needs; sensible
40    defaults.
41 
42    ** Fields
43    *** getter/setters
44    ** Annotations
45
46
47  * ASDF
48
49     ** Stock ASDF-2.26 with conditional patches for the URL-PATHAME and
50        JAR-PATHNAME implementation extensions to ANSI.
51
52  *  ABCL-CONTRIB
53
54     ** ABCL-ASDF
55
56        Network installation of binary artifacts named by Maven POM uris.
57
58        *** checks at runtime if a given class is present in the
59            accessible classloaders
60
61        *** If the check for the presence of a class fails, find a
62            maven-3.0.4 binary locally, execute its Aether connector
63            to retrieve its transitive dependencies from the network.
64
65      ** JSS
66         
67         Java Syntax Sucks.  q.v [lsw2]
68   
69         Extensive bugfixing wrt. method resolution [#229]
70
71      ** JFLI
72
73         A "captured from the wild" version of what @rich.hickey did before Clojure.
74

80  * [#249] PATHNAME merge semantics DWIMs on an inferred type
81
82  Extends ANSI PATHNAME in a non-conforming manner, which was probably
83  already the case.
84
85  * [r13695] Reimplementation of global symbol macros to avoid using
86    the symbol's value slot.

129-------
130
131  * Updated ASDF to 2.019
132
133  * User Manual now contains more polished formating from docstring
134    groveling, an index of symbols, and additional enhancements.

144
145Fixes
146-----
147
148  * [#181][r13718] The implementation now correctly loads ASDF definitions
149    from jar archives.  This had prevented the ABCL-CONTRIB loading
150    mechanism from working.
151
152  * [#177] Made the mechanism for locating the abcl-contrib archive
153    more robust
154

196Features
197--------
198
199 * ABCL works as an SBCL build host
200
201 * Huge (> 64k) literal object support (fixes CL-UNICODE support)
202
203 * The ABCL-ASDF contrib allows the specification of JAR-FILE or
204   JAR-DIRECTORY components that can be resolved via a PATHNAME.  The
205   MVN component bootstraps a Maven3 Aether connector to locally
206   replicate a versioned jar artifact for dynamic inclusion in the
207   CLASSPATH.
208
209Changes
210-------
211
212 * Renamed LispObject.writeToString() method to (more Lispy) printObject()
213
214 * New LispObject.princToString() for user readable output
215
216 * Changed behaviour of LispObject.unreadableString() to signal
217   errors when *PRINT-READABLY* is non-NIL
218
219 * Static initializers moved to <clinit>() (java: static { }) to
220   prevent repeated execution when invoking the constructor multiple times
221
222 * Compiler clean-ups
223
224 * Changed implementation of LABELS to eliminate the need
225   to *always* create a closure
226
227 * File compiler (COMPILE-FILE) clean-ups
228
229 * When calling a function with the wrong number of arguments,
230   report the expected (range) of arguments
231
232 * Upgraded ASDF to 2.017
233
234 * JSS:JLIST-TO-LIST now converts any java.list.List to a Lisp list.
235
236 * The ASDF extensions from JSS for the "jar-directory", "jar-file",
237   and "class-file-directory" types have been refactored into the
238   ABCL-ASDF contrib as well as the *ADDED-TO-CLASSPATH* variable
239   which records dynamically added dependencies.  Use the
240   JSS:ENSURE-COMPATIBILITY function to have JSS include these
241   dependencies. 
242
243*  As long as ABCL-ASDF:ENSURE-MVN-VERSION can dynamically introspect
244   and then load Maven 3 libraries at runtime, ASDF components of type
245   MVN can now be used to specify versioned JVM artifacts.
246
247 * Threads spawned by THREADS:MAKE-THREAD can terminate the Lisp image
248   via the EXT:QUIT and EXT:EXIT functions.
249

451
452* [svn r13203] Create ATOMIC-DEFGENERIC macro, in order to eliminate
453  FMAKUNBOUND calls and the resulting windows where no function is bound to
454  symbols which are the most essential building blocks in CLOS/AMOP.
455
456* [svn r13200] Atomically swap generic functions into place of temporary
457  DEFUNs for all standard-class slot accessors.
458  Note: This addresses the recursive requirement to be able
459  to allocate objects and classes while changing the functions
460  used to create them.
461
462* [svn r13196] Provide more context regarding the reason of autoloading.
463  Note: This change *hugely* helps debugging.

519  "unpacked JAR" situation found by running ABCL in the Glassfish v3
520  servlet container.
521
522* [svn r13096] For arrays, add initialization with the default value
523  of the element type if neither INITIAL-ELEMENT nor INITIAL-CONTENT
524  have been specified.  Found by: dmalves_ (freenode irc nick).
525
526* [svn r13094] Eliminate flushes after every character in
527  javax.scripting support.
528

538-------
539
540* [svn r13141-13146,13156] Make ABCL a well behaving library to better
541  support embedding: NEVER call System.exit() again.  Instead, ABCL now
542  throws org.armedbear.lisp.ProcessingTerminated and
543  org.armedbear.lisp.IntegrityError.
544
545* [svn r13111] Added a "tools" directory available in SVN repository
546  to contain tools for developing ABCL in various states.  The first
547  inhabitant is 'code-grapher.lisp' that provides a prototype to
548  diagram a JVM instruction sequence via graphviz.
549
550* [svn r13101] Reduced verbosity of the AbclScriptEngine.
551
552* [svn r13097-13100] Slight refactoring of PATHNAME code, further
553  specifying URI escaping rules.
554
555* [svn r13091-2] Better error reporting for UnhandledCondition thrown

957  exceptions for NULL and UNBOUND values.
958
959* [svn r12453 et. ff.] Large numbers of the implementation of Java
960  primitives have been declared in a way so that a stack trace
961  provides a much more readable indication of what has been invoked.
962  Primitives which extend Primitive are prefixed with "pf_"; those
963  which extend SpecialOperator are prefixed with "sf_".
964
965* [svn r12422] The internal structure of a jar pathname has changed.
966  Previously a pathname with a DEVICE that was itself a pathname
967  referenced a jar.  This convention was not able to simultaneously
968  represent both jar entries that were themselves jar files (as occurs
969  with packed FASLs within JARs) and devices which refer to drive
970  letters under Windows.  Now, a pathname which refers to a jar has a
971  DEVICE which is a proper list of at most two entries.  The first
972  entry always references the "outer jar", and the second entry (if it
973  exists) references the "inner jar".

983
984* [svn r123406] 'test/lisp/abcl/bugs.lisp' forms a default location to
985  add unit tests for current bug testing.  The intention is to move
986  these tests into the proper location elsewhere in the test suite
987  once they have been fixed.
988
989* [svn r124040] Java tests upgraded to use junit-4.8.1.  Netbeans
990  project runtime classpath now uses compilation results before source
991  directory, allowing the invocation of ABCL in interpreted mode if
992  the Ant 'abcl.compile.lisp.skip' property is set.  Java unit tests
993  for some aspects of jar pathname work added.
994
995*  New toplevel 'doc' directory now contains:

998     inheritance.
999
1000   + [svn r12433] Design and current status for the re-implementation
1001     of jar pathnames.
1002
1003* [svn r12402] Change ABCL unit tests to use the ABCL-TEST-LISP definition
1004  contained in 'abcl.asd'.  Fixed and renabled math-tests.  Added new
1005  tests for work related to handling jar pathnames.
1006
1007* [svn r12401] The REFERENCES-NEEDED-P field of the LOCAL-FUNCTION structure now
1008  tracks whether local functions need the capture of an actual
1009  function object.

1127  Summary of changes:
1128  ------------------
1129  * Fixed generated wrapper for path names with spaces (Windows)
1130  * Fixed ticket #58: Inspection of Java objects in Lisp code
1131  * Restored functionality of the built-in profiler
1132  * Profiler extended with hot-spot counting (as opposed to call counting)
1133  * Stack sampling in the profiler moved to scheduler thread to
1134    reduce impact on the program execution thread
1135  * THE type-checking for the interpreter
1136    (for simple-enough type specifications)
1137  * Added structure argument type checking in structure slot
1138    accessor functions
1139  * Make GENSYM thread-safe
1140  * Various performance fixes found by running the raytracer
1141    from http://www.ffconsultancy.com/languages/ray_tracer/benchmark.html
1142  * Better initarg checking for make-instance and change-class
1143    Fixes ansi-test errors CHANGE-CLASS.1.11, MAKE-INSTANCE.ERROR.3,
1144    MAKE-INSTANCE.ERROR.4, CHANGE-CLASS.ERROR.4 and SHARED-INITIALIZE.ERROR.4
1145  * Improve performance of StackFrames (Erik Huelsmann, Ville Voutilainen,
1146    with input from Peter Graves and Douglas Miles)

1165    now to be considered as deprecated, marked to be removed with
1166    0.22
1167  * Stacktraces now contain calls through Java code relevant to
1168    debugging (Tobias Rittweiler)
1169
1170    Backtrace functionality been moved from EXT:BACKTRACE-AS-LIST to
1171    SYS:BACKTRACE to mark this changes.  The methods SYS:FRAME-TO-STRING
1172    and SYS:FRAME-TO-LIST can be used to inspect the new
1173    LISP_STACK_FRAME and JAVA_STACK_FRAME objects
1174  * Various stream input performance optimizations
1175  * Fixed breakage when combining Gray streams and the pretty printer
1176  * Performance improvements for resolution of non-recursive #=n and #n#

1239  * Resolved infinite recursion on TRACEing the compiler
1240  * Changes on the lisp based build system for parity with Ant
1241  * Fixed interpreter creation in Java Scripting
1242  * libabcl.so no longer created; it was solely about installing
1243     a SIGINT handler. Libraries should not do that.
1244  * boxing of LispObject descendants in JCALL/JCALL-RAW fixed
1245  * OpenBSD and NetBSD platform detection
1246  * fixed special bindings restores in compiled code for
1247     MULTIPLE-VALUE-BIND/LET/LET*/PROGV and function bodies
1248  * introduced variadic list() function to replace list1() ... list9()
1249  * fix return value type of ACOS with complex argument
1250  * fixed precision of multiplication of complex values
1251  * fixed use of COMPILE inside file compilation (i.e. COMPILE-FILE)
1252  * fix expansion of macros inside RESTART-CASE
1253     (fixes RESTART-CASE ANSI failures)
1254  * fix macroexpansion in the precompiler
1255  * Fixnum and Bignum now use a static factory method;
1256      constructors are now private -> increases chances of numbers
1257      being EQ
1258  * Code cleanup in EXPT to fix (EXPT <any-number> <Bignum>)
