6## Features
7
8*  Make LispStackFrame?.UNAVAILABLE_ARG a singleton object,
9   and lazily create the little used portions of the Lisp stack.
10
11    Aggressively cache and control the use of memory by the underlying
12    Lisp stack frame representation by introducing the private
13    LispThread.StackFrame and LispThread.StackSegments classes.
14
15    Contributed by Dmitry Nadezhin.
16
17    LispStackFrame? object are allocated on every
18    LispThread.execute(...) .  However, they are seldom [accessed]
19    ([... verify via] inspect[tion of the] stack trace). This patch
20    delays allocation of LispStackFrame? objects until they are
21    requested.  Raw information about stack frames is stored in
22    stack. Stack is an Object[] array (more precisely a list of [...]4
23    [Mib] Object[] arrays).
24
25    ME: We are going to need a way to try to less agressively grab 4Mib
26    chunks in low memory situations.
27
28    Memory profiling of ABCL shows that the classes with largest
29    allocation count are org.armedbear.lisp.LispStackFrame and
30    org.armedbear.lisp.LispStackFrame.UnavailableArgument.
31
32    Contributed by Dmitry Nadezhin.

36
37*  ASDF 3.0.1.49 shipped with the implementation
38
39*  per function call stack and memory exception handler in CL:COMPILE
40
41   Inline calls to jrun-exception-protected (used by handler-bind to
42   catch out of memory conditions).  This commit saves generation
43   roughly 50 cls files.
44
45   [r14552]: http://abcl.org/trac/changeset/14552
46
47*  SYS:SHA256 audited
48
49    The functionality if the SYS:SHA256 algorithim has been audited for
50    use on inputs of single for files with recently shipping ORCL Java 7
51    implementations (through jdk-1.7.0_51).
52
53    [r14582]:  http://abcl.org/trac/changeset/14582
54
55* Connect to Netbeans via SLIME
56
57    The Netbeans IDE configuration now includes a way to connect to
58    the running-under-jdb ABCL via SLIME.  One needs to be able to
59    load things from 'swank.asd', which currently doesn't work in
60    newer, more github-ier SLIMEs.
61
62* Install 'abcl.jar' and 'abcl-contrib.jar' locally as Maven artifacts
63
64    The Ant `abcl.mvn.install` target now installs build artifacts
65    into the local Maven repository (Olof-Joachim Frahm)
66
67    [r14579]: http://abcl.org/trac/changeset/14606
68
69## Compatibility
70
71*  CL:DIRECTORY
72
73   The implementation specific :RESOLVE-SYMLINKS argument to the ANSI
74   DIRECTORY function has been changed to nil.  This implements
75   behavior closer to SBCL and guarantees that a DIRECTORY operation
76   will not signal a file error.

173Features
174--------
175
176  *  A functioning (A)MOP implementation through the hard work of Rudi
177     Schlatte (@rudi)
178
179  *  The implementation can be used across many more Quicklisp systems
180     through a process of extensive testing.  Thanks @xach!
181
182     Nota bene: all of the following systems need patches to work as
183     of the 2012-10-13 Quicklisp.  All patches have been accepted in
184     at least an initial form by the upstream maintainers.
185
186     ** CLOSER-MOP
187        Quite possible with local patches
188     ** CFFI
189       Needs patches to 2012-10-13 Quicklisp.  [!!?]
190       *** Dynamic interfaces idempotent across process -- no more reloading
191     ** HUNCHENTOOT
192       *** some bugs with underlying streams to be fixed in abcl-1.2-dev
193     ** CXML
194        Basic XML parsing works.  XPath still borked. [???]     
195  *  Java 5 bytecode Compiler
196
197     The internal Lisp-to-Java bytecode compiler has been hardened by
198     regression testing across Quicklisp libraries. 
199
200     **  Extensive interpreter/compiler bug fixes due to access to cl-test-suite [???] @antov
201     ** large objects (?!?)
202
203  *  The facility to construct runtime classes via JNEW-RUNTIME-CLASS (@astalla)
204
205    Pretty close to full coverage of primtives for creating synthethic
206    java classes at runtime.  Easy to extend with your needs; sensible
207    defaults.
208 
209    ** Fields
210    *** getter/setters
211    ** Annotations
212
213
214  * ASDF
215
216     ** Stock ASDF-2.26.6 which includes #+abcl conditional patches
217        for the URL-PATHAME and JAR-PATHNAME implementation extensions
218        to ANSI.
219
220  *  ABCL-CONTRIB
221
222     ** ABCL-ASDF
223
224        Network installation of binary artifacts named by Maven POM uris.
225
226        *** checks at runtime if a given class is present in the
227            accessible classloaders
228
229        *** If the check for the presence of a class fails, find a
230            maven-3.0.4 binary locally, execute its Aether connector
231            to retrieve its transitive dependencies from the network.
232
233      ** JSS
234         
235         Java Syntax Sucks.  q.v [lsw2]
236   
237         Extensive bugfixing wrt. method resolution [#229]
238
239      ** JFLI
240
241         A "captured from the wild" version of what @rich.hickey did before Clojure.

353
354  * Updated ASDF to 2.019
355
356  * User Manual now contains more polished formating from docstring
357    groveling, an index of symbols, and additional enhancements.

367
368Fixes
369-----
370
371  * [#181][r13718] The implementation now correctly loads ASDF definitions
372    from jar archives.  This had prevented the ABCL-CONTRIB loading
373    mechanism from working.
374
375  * [#177] Made the mechanism for locating the abcl-contrib archive

419Features
420--------
421
422 * ABCL works as an SBCL build host
423
424 * Huge (> 64k) literal object support (fixes CL-UNICODE support)
425
426 * The ABCL-ASDF contrib allows the specification of JAR-FILE or
427   JAR-DIRECTORY components that can be resolved via a PATHNAME.  The
428   MVN component bootstraps a Maven3 Aether connector to locally
429   replicate a versioned jar artifact for dynamic inclusion in the
430   CLASSPATH.
431
432Changes
433-------
434
435 * Renamed LispObject.writeToString() method to (more Lispy) printObject()
436
437 * New LispObject.princToString() for user readable output
438
439 * Changed behaviour of LispObject.unreadableString() to signal
440   errors when *PRINT-READABLY* is non-NIL
441
442 * Static initializers moved to <clinit>() (java: static { }) to
443   prevent repeated execution when invoking the constructor multiple times
444
445 * Compiler clean-ups
446
447 * Changed implementation of LABELS to eliminate the need
448   to *always* create a closure
449
450 * File compiler (COMPILE-FILE) clean-ups
451
452 * When calling a function with the wrong number of arguments,
453   report the expected (range) of arguments
454
455 * Upgraded ASDF to 2.017
456
457 * JSS:JLIST-TO-LIST now converts any java.list.List to a Lisp list.
458
459 * The ASDF extensions from JSS for the "jar-directory", "jar-file",
460   and "class-file-directory" types have been refactored into the
461   ABCL-ASDF contrib as well as the *ADDED-TO-CLASSPATH* variable
462   which records dynamically added dependencies.  Use the
463   JSS:ENSURE-COMPATIBILITY function to have JSS include these
464   dependencies. 
465
466*  As long as ABCL-ASDF:ENSURE-MVN-VERSION can dynamically introspect
467   and then load Maven 3 libraries at runtime, ASDF components of type
468   MVN can now be used to specify versioned JVM artifacts.
469
470 * Threads spawned by THREADS:MAKE-THREAD can terminate the Lisp image
471   via the EXT:QUIT and EXT:EXIT functions.

1087Fixes/Optimizations
1088-------------------
1089
1090* [svn r12526] Unbinding of PROGV bound variables on local transfer
1091  of control (within-java-function jump targets)
1092
1093* [svn r12510] The new ansi-test WITH-STANDARD-IO-SYNTAX.23 passes.
1094  Our with-standard-io-syntax implementation now correctly resets all necessary
1095  pprint variables. Patch by Douglas R. Miles, thanks for the contribution!
1096
1097* [svn r12485] Pathnames starting with "." can now have TYPE.
1098
1099* [svn r12484] FASLs containing "." characters not used to indicate
1100  type (i.e. ".foo.bar.baz.abcl") can now be loaded.
1101
1102* [svn r12422] Pathname.java URL contructor under Windows now properly
1103  interprets the drive letter.
1104
1105* [svn r12449] The 'abcl.jar' produced by Netbeans now contains a valid
1106  manifest (found by Paul Griffionen).
1107
1108* [svn r12441] ZipCache now caches all references to ZipFiles based on
1109  the last-modified time for local files.  Remote files are always
1110  retrieved due to problems in the underlying JVM code.
1111
1112  SYS:REMOVE-ZIP-CACHE implements a way to invalidate an entry given a
1113  pathname.
1114
1115* [svn r12439] Remove duplication of java options in Windows
1116  'abcl.bat' script.
1117
1118* [svn r12437] CHAR-CODE-LIMIT is the upper execlusive limit (found by
1119  Paul Griffionen).
1120
1121* [svn r12436] Describe formatting was missing a newline (reported by
1122  Blake McBride).
1123
1124* [svn 12469] Ensure that FILE-ERROR always has a value (possibly NIL)
1125  for its PATHNAME member.
1126
1127* [svn r14222] MERGE-PATHNAMES no longer potentially shares structure
1128  between its result and *DEFAULT-PATHNAME-DEFAULTS*.
1129
1130* [svn r12416] Fixed ANSI LAMBDA.nn test failures caused by errors in
1131  lambda inlining.
1132
1133* [svn r12417] [ticket:83] Fix TRANSLATE-LOGICAL-PATHNAME regression.
1134  (Alan Ruttenberg).
1135
1136* [svn r12412] Optimize memory efficiency of FORMAT by use of a
1137  hashtable rather than a CHAR-CODE-LIMIT array.
1138
1139* [svn r12408] FIND-SYMBOL requires a  string argument.
1140
1141* [svn r12400] Make NIL (as symbol) available to the compiler.
1142
1143* [svn r12398] Move lambda list analysis to compile time where possible.
1144
1145* [svn r12397] BROADCAST-STREAM obeys default external format fixing
1146  ANSI MAKE-BROADCAST-STREAM.8.
1147
1148* [svn r12395] Improve arglist display for SLIME (Matthias Hölzl).
1149
1150* [svn r12394] Optimize array utilization in closures.
1151
1152* [svn r12393] Optimize array functions in compiler which don't
1153  require clearing the VALUES array.
1154
1155* [svn r12392] Optimize/normalize aspects of boot.lisp
1156
1157* [svn r12391] Prevent duplicated subclasses form occuring.
1158
1159
1160Other
1161-----
1162
1163* [svn r12447] SYS::*MODULE-PROVIDER-FUNCTION* now provides a mechanism
1164  to extend the REQUIRE resolver mechanism at runtime.
1165
1166* [svn r12430] Ant based build no longer writes temporary files to
1167  contain the Lisp build instructions.
1168
1169* [svn r12481] STANDARD-CLASS now has slots to be inherited by
1170  deriving metaclasses in support of the (in progress) work on
1171  metaclass.
1172
1173* [svn r12425] No longer ignore the METACLASS defclass option in
1174  support of the (in progress) work on metaclass
1175
1176* [svn r12422] SYS::*LOAD-TRUENAME-FASL* now contains the TRUENAME of
1177  the Java "*.cls" component when loading a packed FASL.
1178
1179* [svn r12461] Human readable Java representations for class cast
1180  exceptions for NULL and UNBOUND values.
1181
1182* [svn r12453 et. ff.] Large numbers of the implementation of Java
1183  primitives have been declared in a way so that a stack trace
1184  provides a much more readable indication of what has been invoked.
1185  Primitives which extend Primitive are prefixed with "pf_"; those
1186  which extend SpecialOperator are prefixed with "sf_".
1187
1188* [svn r12422] The internal structure of a jar pathname has changed.
1189  Previously a pathname with a DEVICE that was itself a pathname
1190  referenced a jar.  This convention was not able to simultaneously
1191  represent both jar entries that were themselves jar files (as occurs
1192  with packed FASLs within JARs) and devices which refer to drive
1193  letters under Windows.  Now, a pathname which refers to a jar has a
1194  DEVICE which is a proper list of at most two entries.  The first
1195  entry always references the "outer jar", and the second entry (if it
1196  exists) references the "inner jar".
1197
1198* [svn r12419] Ant 'abcl.release' target centralizes the build steps
1199  necessary for creating releases.
1200
1201* [svn r12409] Compiler now rewrites function calls with (LAMBDA 
) as
1202  the operator to LET* forms.
1203
1204* [svn r12415] CLASS-FILE renamed to ABCL-CLASS-FILE to prepare for
1205  (in progress) reworking of Stream inheritance.
1206
1207* [svn r123406] 'test/lisp/abcl/bugs.lisp' forms a default location to
1208  add unit tests for current bug testing.  The intention is to move
1209  these tests into the proper location elsewhere in the test suite
1210  once they have been fixed.
1211
1212* [svn r124040] Java tests upgraded to use junit-4.8.1.  Netbeans
1213  project runtime classpath now uses compilation results before source
1214  directory, allowing the invocation of ABCL in interpreted mode if
1215  the Ant 'abcl.compile.lisp.skip' property is set.  Java unit tests
1216  for some aspects of jar pathname work added.
1217
1218*  New toplevel 'doc' directory now contains:
1219
1220   + [svn r12410] Design for the (in progress) reworking of the Stream
1221     inheritance.
1222
1223   + [svn r12433] Design and current status for the re-implementation
1224     of jar pathnames.
1225
1226* [svn r12402] Change ABCL unit tests to use the ABCL-TEST-LISP definition
1227  contained in 'abcl.asd'.  Fixed and renabled math-tests.  Added new
1228  tests for work related to handling jar pathnames.
1229
1230* [svn r12401] The REFERENCES-NEEDED-P field of the LOCAL-FUNCTION structure now
1231  tracks whether local functions need the capture of an actual
1232  function object.
