[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 16.1.2, Package name: ecl-16.1.2, Maintainer: asau

ECL stands for Embeddable Common-Lisp. The ECL project is an effort to
modernize Giuseppe Attardi's ECL environment to produce an implementation of
the Common-Lisp language which complies to the ANSI X3J13 definition of the
language.

The current ECL implementation features:
* A bytecodes compiler and interpreter.
* A translator to C.
* An interface to foreign functions.
* A dynamic loader.
* The possibility to build standalone executables.
* The Common-Lisp Object System (CLOS).
* Conditions and restarts for handling errors.
* Sockets as ordinary streams.
* The Gnu Multiprecision library for fast bignum operations.
* A simple conservative mark & sweep garbage collector.
* The Boehm-Weiser garbage collector.
* Threads using the POSIX threads library.
* CLX, an X11 client not needing extra X11 libraries.
* Unicode.

Update to ECL 16.1.2

Changes since 16.0.0

 * API changes

 - si:do-setf accepts optional parameter stores.  New lambda-list:
   (access-fn function &optional (stores `(,(gensym))))
   This change is backward compatible.

 - New MP functions:
   mp:with-rwlock
   mp:try-get-semaphore (non-blocking)
   mp:mailbox-try-read  (non-blocking)
   mp:mailbox-try-send  (non-blocking)

 - Added back removed C interfaces
   ecl_import_current_thread
   ecl_release_current_thread

 - When cl-truename encounters a broken symlink, it returns its path
   instead of signalling a file-error

 - Deprecated variables has been removed
   c::*suppress-compiler-warnings*, c::*suppress-compiler-notes*

 - Random state might be initialized by a random seed (truncated to
   32bit value) or by a precomputed array.

   Latter is designed to allow reading back the printed random state
   (when printed readably), not as an array to initialize the random
   state.

 - C99 supporting compiler is mandatory for C backend.

 - COMPILER::*cc_is_cxx*: New variable to switch the output extension of
   emitted compiler code to ".cxx" when configured with \ 
"--with-c++". This
   eliminates compiler warnings that compiling C++ with a ".c" extension is
   deprecated; this is seen mostly with Clang++.

 - Added Clang-specific pragmas to disable return type, unused value and
   excessive parentheses warnings, which are fairly harmless, but annoying
   and clutter user output.

 - GRAY:CLOSE isn't specialized on T to preserve compatibility with some
   libraries.

 * Enhancements:

 - Added code walker (present as *feature* :walker)

 - Testing framework cleanup

 - Format fallbacks to prin1 if infinity or NaN are passed to it

 - Annotations are added at runtime (better integration with SLIME)

 - Mersenne-Twister RNG has new 64 bit implementation for appropriate
   machines

 - Add sockets implementation for android platform

 - Add android build target (official android support)

 * Issues fixed:

 - si:open-unix-socket-stream accepts both string and base-string
   (automatic coercion is performed)

 - Long form of DEFSETF accepts multiple-values as a store forms:

   (defsetf gah (x) (y z) `(list ,x ,y ,z))
   (setf (gah 3) (values 3 4))

 - Building with single-threaded boehm works if ECL threads are disabled

 - Using labels works with sharp-S-reader

   (read-from-string
    "(#1=\"Hello\" #S(sharp-s-reader.1.example-struct :A #1#))")

 - Generated C code works well with IEEE 754 infinities
   (regression tests created)

 - User-defined heap sizes can now exceed the size of a fixnum on 32-bit

 - The heap size limit was intended to be 1GB on 32-bit or 4GB on 64-bit
   but inconsistency between ECL_FIXNUM_BITS and FIXNUM_BITS in the code
   prevented the heap to grow for 64-bit.  This now occurs, and a few
   other less visible bugs were fixed by restoring consistency to
   ECL_FIXNUM_BITS.

 - EXT:EXTERNAL-PROCESS-WAIT potential race condition fix

 - Building with object files not created by ECL works (CFFI wrappers)

 - Regression regarding initialization of build by ECL libraries from
   external code fixed. Static and shared libraries initialization
   funcitons has predetermined name while object files has randomized
   names.

 - Random state initial state generation was buggy and insecure (entropy
   from urandom was rejected)

 - Fix `listen' on streams when FILE_CNT isn't available (use read instad
   of fread)

 - `FIND' compiled with C compiler didn't respect `START' nor `END'
   arguments. Compiler macro is fixed now and should work as expected

 - `compute-applicable-methods-using-classes` bugfix

Log message:
Update to ECL 16.0.0.
Based on changes from Matthew Mondor as forwarded by Kamil Rytarowski.

Changes since 15.3.7:
 API changes
 - There is no UFFI nickname for FFI package - we piggyback on
   cffi-uffi-compat for UFFI dependent systems (our UFFI wasn't version 2.0
   compatible and there were problems with ADSF dependencies on UFFI - it
   wasn't a system)
 - CLOS has the new nickname "MOP"
 - The new ext:run-program :error argument can automatically create a
   separate stream if provided with the :stream keyword.
   The external-process structure also has a new field to hold that stream.
 - ext:run-program accepts new arguments - :if-input-does-not-exist,
   :if-error-exists and :external-format
 - ext:system no longer binds *standard-input* and *standard-output* and
   now ignores input and output (use ext:run-program for more control)
 - methods can be specialized on both single-float and double-float
   (built-in classes were added for them)
 - LET/FLET/LABELS will signal error if parameter of the same name will
   appear multiple times
 - lambda lists with repeated required parameter name are considered invalid
 - deprecated configure options "--with-system-boehm=x" and
   "--enable-slow-config" removed

 Enhancements:
 - Verification if manual is up-to-date, providing corrections for
   outdated parts
 - Documentation is now included in the main repository under the
   toplevel directory `doc'
 - Update libffi to version 3.2.1
 - Update asdf to version 3.1.5.4
 - Update Boehm-Demers-Weiser garbage collector to version 7.4.2
 - Pathname string-parts internal representation is now character,
   not base-char
 - Dead code removal, tabulators were replaced by spaces
 - Better quality of generated code (explicit casting when necessary)

 Issues fixed:
 - Various fixes of bogus declarations
 - Remove deprecated GC calls
 - ROTATEF, SHIFTF, PSETF reworked to conform to the ANSI standard.
   Places were handled improperly in regard of multiple values.
 - Improved unicode support in character handling
 - Format handles floats and exponentials correctly (major format rework)
 - Stack limits refinements and cleanup, inconsistency and bug fixes
 - Duplicate large block deallocation with GMP 6.0.0a fixed
 - ECL builds on OpenBSD with threads enabled
 - Closures put in mapcar work as expected in both compiled and
   interpreted code
 - Improved readtable-case handling (:invert and character literals now
   conform)
 - Library initialization functions have unique names - no risk of
   clashing symbol names in object files
 - Format float bug fixed, when width and fdigits were not set, but k was
 - `logical-pathname-translations' now throws an error if logical
   pathname wasn't defined yet, to conform with ANSI (it used to return NIL)
 - Wildcards in logical pathname translations are replaced correctly
 - Regression testing framework and unit tests cleanup
 - deftype ANSI conformity fix (deftype accepts macro labda-lists)
 - ECL built with MSVC doesn't crash when Control-C is pressed
 - Other minor tweaks

Changes in 15.3.7 since 15.2.21:
 Issues fixed:
 - DEFUN functions not defined as toplevel forms were also directly
   referenced by other code in the same file.
 - STABLE-SORT works as desired (bogus optimization for strings fixed).
 - broken --with-sse=yes configure flag works once again.

 Enhancements:
 - autoconf scripts are rewritten to support version 2.69 stack.
 - stack direction is now correctly determined, fixing gcc 5.x builds.
 - compilation of ECL under MSVC (2008/2010/2012) even with custom
   code pages.
 - In compiled code it is possible to declare variables to have a C
   type such as in (declare (:double a)) and then the variable is
   enforced to be unboxed to such type.
 - New form FFI:C-PROGN used to interleave C statements with lisp
   code, where the lisp code may refer to any number of variables.
   Example:
       (lambda (i)
         (let* ((limit i)
                (iterator 0))
           (declare (:int limit iterator))
           (ffi:c-progn (limit iterator)
                        "for (#1 = 0; #1 < #0; #1++) {"
                        (print iterator)
                        "}")))

Changes in 15.2.21 since 13.5.1:
 - Features coverity scan model, ffi-unload-module implementation,
   probably more.
 - Build system enhancements, parallel builds, fixes, simplifications,
   cleanups, maintenance.  minor cleanup, maintenance.
 - Numerous fixes.

Update to ECL 13.5.1

ECL 13.5.1
==========

* Visible changes:

- ECL now reports #+UNIX for all compatible systems, including *BSD ones.

* Compiler fixes:

- Minor readability improvements in the C code.

- MULTIPLE-VALUE-BIND compiles using MULTIPLE-VALUE-SETQ and now both are
  better optimized, generating simpler C code.

- The type checking routine for LOGAND was producing spurious warnings.

- (LDB (BYTE ...) ...) no longer conses a BYTE object.

- Added optimizations for MASK-FIELD, DPB, DEPOSIT-FIELD, LDB-TEST and LDB.

- CONSTANT-VALUE-P and friends now use the (compiler) environment.

- No optional type check generated for constant values.

- Declare the temporary variables in DEFMACRO/DESTRUCTURING-BIND as IGNORABLE

- ECL now accepts WHILE/IF before FOR/AS, a construct that is not ANSI
  An example: (LOOP FOR I IN LIST WHILE (SOME-TEST I) FOR X = (F I) ... )

* Common Lisp fixes:

- CONSTANTP now performs a bit more work, macroexpanding forms.

- ENSURE-DIRECTORIES-EXIST ignores the host and device from the original
  pathname when creating the directories.

- In FORMAT, printing of floating point numbers could lead to an infinite loop.

- ROUND, FLOOR, CEILING and TRUNCATE have been reorganized and work faster with
  rational numbers.

- (CONCATENATE 'SIMPLE-BASE-STRING ...) returned an ordinary string.

- MAKE-ARRAY did not terminate strings with #\Null (needed internally by the C
  code).

- (SETF DOCUMENTATION) did not operate on functions because the function object
  documentation had precedence over the annotation.

- Added the whole Unicode character database to the C library. This means ECL
  can now interpret all Unicode character names properly, and print them as
  well. ECL now also recognizes all ASCII control-character abbreviations

- Print integers using upcase letters for radix > 10

- New functions RATIOP, {SINGLE,SHORT,DOUBLE,LONG}-FLOAT-P help avoid consing
  in TYPEP

- HASH-TABLE-COUNT did not work with weak hashes: it did not update the count
  of live cells (Note, however, that this function is by definition not
  reliable, just a hint, since a garbage collection may happen while the count
  is being computed)

- ECL no longer uses :READ-ONLY declarations in the SETF expansions because
  there is code out there that modifies the values variables.

- PROGV can now 'unbind' variables when the list of variables is longer than
  the list of values.

* CLOS:

- Added built in classes FIXNUM and BIGNUM.

- Eliminated code for accessing slots that was no longer used. Removed also
  redundant code.

- Updating a class (due to a change in metaclass) now forces updating its
  children

- UPDATE-INSTANCE-FOR-REDEFINED-CLASS received an alist instead of a
  propertly-list as last argument

- PRINT-OBJECT did not have a working default for built in classes.

* Extensions:

- SYSTEM must use the POSIX shell, which usually lives in /bin/sh.

- CLX now uses recursive locks.

- ASDF upgraded to version 2.32, including the ASDF-BUNDLE facility, which
  supersedes ECL's own implementation of precompiled libraries.

- MAKE-INSTANCE, SHARED-INITIALIZE, REINITIALIZE-INSTANCE now work on
  structures as well.
