After almost a year of development we are proud to present a new
release of ECL tagged with version
16.1.3. All changes are backward
compatible fixing bugs and other issues, implementing new interfaces
and cleaning up the code base.
ECL manual has been updated in a few places. Work on a new documentation is still pending. New documentation is still incomplete, but you may see it here: https://common-lisp.net/project/ecl/static/ecldoc/.
Before this release we have performed extensive tests on many platforms (Linux, FreeBSD, OpenBSD, NetBSD, OSX, Windows MSVC, Windows MinGW, Windows Cygwin, Android and Haiku). For details please consult https://gitlab.com/embeddable-common-lisp/ecl/issues/307. Extra attention has been paid to Windows testing to improve that platform support.
This release is available for download in form of a source archive:

Added better interface for package-locks.
ext:package-locked-p package ext:lock-package package ext:unlock-package package ext:without-package-locks &body body ext:with-unlocked-packages (&rest packages) &body body
To use these functions user has to require the module
defpackageaccepts new option
lockto allow locking package on creation:
(defpackage foo (:lock t))
mp:holding-lock-p: introduce new function for multiprocessing. Function verifies if lock is hold by the thread which calls the function. Usage:
make-random-state: fix problem with simple-vectors. The correct initialization types for
(OR RANDOM-STATE FIXNUM (MEMBER T NIL)).
Initializing a random state with an appropriate array (element type and arity dependent on platform) is also possible.
ext:random-state-array: new extension for random-states. Usage:
ext:terminate-process: new extension for external processes. Usage:
(ext:terminate-process process)with a second, optional boolean argument whenever termination should be forced or not.
CDR-5were already implemented, CDR-14 made us to list them in
if ECL is build with
:CXX-COREis present in
deprecated configure option
--with-local-gmphas been removed - use
--enable-gmp(defaults to auto).
configure options has been revised.
ASDF has been upgraded to version 184.108.40.206 (with a few patches scheduled for 3.2.0).
bundled CLX has been purged. Lately I've fixed ECL support on portable CLX maintained by sharplispers on https://github.com/sharplispers/clx (available via QuickLisp).
initial port for the Haiku platform. The port is done by Kacper Kasper's work, one of Haiku developers. Threads are not supported yet.
refactored ECL internal tests framework. Tests in
src/testsare now asdf-loadable (with
load-source-op) and divided into test suites.
make checktarget runs all regression and feature tests which aren't supposed to fail.
removed 15000 lines of obsolete code. Files not included in the buildsystem but lingering in the codebase or options failing to build. All info is added in the new documentation in the section "Removed interfaces".
improved man page and help output. Man page now contains up-to-date list of flags, as well as explanation of flag's behavior.
deprecated long flags with one dash, added two-dash version. Flags that aren't one-character, but start with one dash (e.g.
-eval) are now deprecated; long version
--evalwas added instead.
indented C/C++ code to follow emacs's gnu C style. This is a first step towards coding standards in the documentation. Additionally all in the src/c/ directory are listed in the appropraite documentation section (new-doc).
list_current_directory in unixfsys.d. Function was obfuscated with ifdefs with non-even pairs of
ECL signals floating point exceptions in top-level console.
mp:rwlockis treated as built-in class (previously process crashed if
class-ofwas called on such object).
ECL builds now succesfully with
ext:file-stream-fd: doesn't cause an internal-error if called with something not being a
stable-sort: bugfix and improvement in speed. Adapted from SBCL by Diogo Franco.
*type specifier as abbreviation of
Tas described in
2.4.3 Type Specifiersof the specification.
MOP: fix problemes when redefining non-standard and anonymous classes. Bugs identified and fixed by Pascal Costanza.
getcwd: fix issue with too long pathname. This fixes the regression, which crashed ECL at start when pathname exceeded 128 characters limit.
make-random-state: fix a problem with simple-vectors. Until now
#$reader macro accepted simple vectors as an argument, what lead to bugs if vector didn't match specific requirements like the element type or the arity. Now we sanitize this.
make-load-form: provide implementation for random-state objects.
thread fix on msvc: on windows importing thread was closing the thread handler so the thread wakeup wasn't working because the handler is not more valid.
import thread wasn't set upping a proper environment: on some case the thread was mistakenly thinking that the thread was already registered.
ECL_RESTART_CASEdidn't work as expected. Bug identified and fixed by Vadim Penzin.
