Features
--------

 * ABCL works as an SBCL build host

 * Huge (> 64k) literal object support (fixes CL-UNICODE support)

46
47
48
49
50
 * The ABCL-ASDF contrib allows the specification of JAR-FILE or
   JAR-DIRECTORY components that can be resolved via a PATHNAME.  The
   MVN component bootstraps a Maven3 Aether connector to locally
   replicate a versioned jar artifact for dynamic inclusion in the
   CLASSPATH.

Changes
-------

55
 * Renamed LispObject.writeToString() method to (more Lispy) printObject()
56
57
58
59
60
61

 * New LispObject.princToString() for user readable output

 * Changed behaviour of LispObject.unreadableString() to signal
   errors when *PRINT-READABLY* is non-NIL

62
63
64
65
66
67
68
69
70
71
 * Static initializers moved to <clinit>() (java: static { }) to
   prevent repeated execution when invoking the constructor multiple times

 * Compiler clean-ups

 * Changed implementation of LABELS to eliminate the need
   to *always* create a closure

 * File compiler (COMPILE-FILE) clean-ups

72
73
74
75
76
 * When calling a function with the wrong number of arguments,
   report the expected (range) of arguments

 * Upgraded ASDF to 2.017

77
78
79
80
81
82
83
84
85
 * JSS:JLIST-TO-LIST now converts any java.list.List to a Lisp list.

 * The ASDF extensions from JSS for the "jar-directory", "jar-file",
   and "class-file-directory" types have been refactored into the
   ABCL-ASDF contrib as well as the *ADDED-TO-CLASSPATH* variable
   which records dynamically added dependencies.  Use the
   JSS:ENSURE-COMPATIBILITY function to have JSS include these
   dependencies.  

86
87
88
89
*  As long as ABCL-ASDF:ENSURE-MVN-VERSION can dynamically introspect
   and then load Maven 3 libraries at runtime, ASDF components of type
   MVN can now be used to specify versioned JVM artifacts.

90
91
92
93
 * Threads spawned by THREADS:MAKE-THREAD can terminate the Lisp image
   via the EXT:QUIT and EXT:EXIT functions.

* Ant target for generating Javadoc.

Fixes
-----

* [svn r13229] Remove non-existing THREAD-LOCK and THREAD-UNLOCK from autoloads.

* [svn 13228] Fix incorrect elimination of named local functions
  declared inline when they're actually reified in the flet/labels body.

* [svn r13217] Forward-referenced classes work properly now.

* [svn r13209] Add initarg checking to REINITIALIZE-INSTANCE.

* [svn r13204] FINALIZE-INHERITANCE is (more) AMOP compatible.

  symbols which are the most essential building blocks in CLOS/AMOP.

* [svn r13200] Atomically swap generic functions into place of temporary
  DEFUNs for all standard-class slot accessors.
  Note: This addresses the recursive requirement to be able
  to allocate objects and classes while changing the functions
  used to create them.

* [svn r13196] Provide more context regarding the reason of autoloading.
  Note: This change *hugely* helps debugging.

* [svn r13189] Fix MACROEXPAND-ALL autoloader which should be
  loaded from 'format.lisp'.

* [svn r13188] Fix DEFSTRUCT trying to generate accessors named NIL

* [svn r13187] Fix #125: FASL reader should not convert symbol
  case [Qi FASL loading issues].

345
346
347

* [svn r13078] JVM::MAKE-CLASS-INTERFACE-FILE provides an interface
  for the creation of Java interfaces as serialized by the new

  javax.scripting support.
371
372
373
374
375

* [svn r13090] Make --batch exit, use Lisp.exit() in places where

  output to be flushed.

376
377

384
385
386
* [svn r13141-13146,13156] Make ABCL a well behaving library to better

391
392

* [svn r13111] Added a "tools" directory available in SVN repository

  structure, respectively.

669
* [svn r12505] All calls to anonymous functions and local functions that have
670
671
672
  been declared inline are now converted to LET* forms, reducing stack usage
  and the number of generated classes.

673
* [svn r12487] An initial port ASDF-INSTALL now forms the first ABCL
674
675
676
  contrib.  Such contribs are optionally built by the Ant target

  under Windows in its present state.
677

678
* [svn r12447] [ticket:80] REQUIRE now searches for ASDF systems.
679

680

  all work both for local and remote jar pathnames of the form
683
684
  "jar:URL!/JAR-ENTRY".

685
  The loading ASDF systems from jar files is now possible.
686

687
  SYS:PATHNAME-JAR-P predicate signals whether a pathname references a
688
  jar.
689

690

691

692
  SYS:UNZIP implemented to unpack ZIP files.
693

  from a Java byte array stream.

* [svn 12402] ABCL.TEST.LISP:RUN-MATCHING will now execute that subset
  of tests which match a string.


Fixes/Optimizations
-------------------
709

710
711
712

714
715
716
* [svn r12510] The new ansi-test WITH-STANDARD-IO-SYNTAX.23 passes.

717
* [svn r12485] Pathnames starting with "." can now have TYPE.
718

719
* [svn r12484] FASLs containing "." characters not used to indicate
720
  type (i.e. ".foo.bar.baz.abcl") can now be loaded.
721

722
* [svn r12422] Pathname.java URL contructor under Windows now properly
723
  interprets the drive letter.
724

725
726
* [svn r12449] The 'abcl.jar' produced by Netbeans now contains a valid
  manifest (found by Paul Griffionen).
727

728
729
* [svn r12441] ZipCache now caches all references to ZipFiles based on
  the last-modified time for local files.  Remote files are always
730
731

  pathname.
734

  'abcl.bat' script.
737

738

Other
-----

783
* [svn r12447] SYS::*MODULE-PROVIDER-FUNCTION* now provides a mechanism
784
785
786
787
788
789
790
791
792
793
794
795
796
  to extend the REQUIRE resolver mechanism at runtime.

* [svn r12430] Ant based build no longer writes temporary files to
  contain the Lisp build instructions.

* [svn r12481] STANDARD-CLASS now has slots to be inherited by
  deriving metaclasses in support of the (in progress) work on
  metaclass.

* [svn r12425] No longer ignore the METACLASS defclass option in
  support of the (in progress) work on metaclass

* [svn r12422] SYS::*LOAD-TRUENAME-FASL* now contains the TRUENAME of
797
  the Java "*.cls" component when loading a packed FASL.
798
799
800
801

* [svn r12461] Human readable Java representations for class cast
  exceptions for NULL and UNBOUND values.

802
* [svn r12453 et. ff.] Large numbers of the implementation of Java
803
804
805
806
  primitives have been declared in a way so that a stack trace
  provides a much more readable indication of what has been invoked.
  Primitives which extend Primitive are prefixed with "pf_"; those
  which extend SpecialOperator are prefixed with "sf_".
807

808
* [svn r12422] The internal structure of a jar pathname has changed.

  Previously a pathname with a DEVICE that was itself a pathname
  referenced a jar.  This convention was not able to simultaneously
  represent both jar entries that were themselves jar files (as occurs
  with packed FASLs within JARs) and devices which refer to drive
  letters under Windows.  Now, a pathname which refers to a jar has a
  DEVICE which is a proper list of at most two entries.  The first
  entry always references the "outer jar", and the second entry (if it
  exists) references the "inner jar".

* [svn r12419] Ant 'abcl.release' target centralizes the build steps
  necessary for creating releases.

* [svn r12409] Compiler now rewrites function calls with (LAMBDA …) as
  the operator to LET* forms.

* [svn r12415] CLASS-FILE renamed to ABCL-CLASS-FILE to prepare for
  (in progress) reworking of Stream inheritance.

* [svn r123406] 'test/lisp/abcl/bugs.lisp' forms a default location to
  add unit tests for current bug testing.  The intention is to move
  these tests into the proper location elsewhere in the test suite
  once they have been fixed.

* [svn r124040] Java tests upgraded to use junit-4.8.1.  Netbeans
  project runtime classpath now uses compilation results before source
  directory, allowing the invocation of ABCL in interpreted mode if
  the Ant 'abcl.compile.lisp.skip' property is set.  Java unit tests
  for some aspects of jar pathname work added.

*  New toplevel 'doc' directory now contains:
839

840
841
   + [svn r12410] Design for the (in progress) reworking of the Stream
     inheritance.
842

843
844
845
846
847
   + [svn r12433] Design and current status for the re-implementation
     of jar pathnames.

* [svn r12402] Change ABCL unit tests to use the ABCL-TEST-LISP definition
  contained in 'abcl.asd'.  Fixed and renabled math-tests.  Added new
848
  tests for work related to handling jar pathnames.
849
850
851
852

* [svn r12401] The REFERENCES-NEEDED-P field of the LOCAL-FUNCTION structure now
  tracks whether local functions need the capture of an actual
  function object.

  * Increased clarity on licensing (Classpath exception
     mentioned in COPYING, removed LICENSE)
  * Resolved infinite recursion on TRACEing the compiler
  * Changes on the lisp based build system for parity with Ant
  * Fixed interpreter creation in Java Scripting
  * libabcl.so no longer created; it was solely about installing
     a SIGINT handler. Libraries should not do that.
  * boxing of LispObject descendants in JCALL/JCALL-RAW fixed
  * OpenBSD and NetBSD platform detection
  * fixed special bindings restores in compiled code for
     MULTIPLE-VALUE-BIND/LET/LET*/PROGV and function bodies
  * introduced variadic list() function to replace list1() ... list9()
  * fix return value type of ACOS with complex argument
  * fixed precision of multiplication of complex values
  * fixed use of COMPILE inside file compilation (i.e. COMPILE-FILE)
  * fix expansion of macros inside RESTART-CASE
     (fixes RESTART-CASE ANSI failures)
  * fix macroexpansion in the precompiler
  * Fixnum and Bignum now use a static factory method;
      constructors are now private -> increases chances of numbers
      being EQ
1101
  * Code cleanup in EXPT to fix (EXPT <any-number> <Bignum>)
