-ECL 10.3.2:
+ECL 10.4.1:
===========
* Bugs fixed:
* Visible changes:
- - The source location annotator records the original pathnames, not the
- truenames. This allows in particular moving ECL's core files.
+ - The source location annotator records the original pathnames instead of
+ truenames. This allows Slime to find out the ECL sources even if they
+ have been moved.
- The signal servicing thread now carries the name SI:SIGNAL-SERVICING, which
is different from the name of the threads that are created to actually
- handle those signals.
+ handle those signals. Users should avoid killing SI:SIGNAL-SERVICING.
- - FFI:CLINES admits @lisp-object notation in the strings.
-
- - ECL's contributed modules can now be used in standalone programs, for they
- are now stored both in FASL form and as statically linked libraries.
-
- - ASDF:MAKE-BUILD now takes a new keyword argument, :MOVE-HERE, that allows
- moving the files that ASDF creates to the current directory. :MOVE-HERE can
- be a flag, in which case the files are output at ./asdf-output/ or a
- pathname designator, in which case the directories are created.
+ - FFI:CLINES admits the notation @lisp-object, just like FFI:C-INLINE. The
+ result is that @lisp-object gets replaced with a pointer to the given
+ lisp object, created at run time.
- Gray streams implement a new generic function, GRAY:STREAM-FILE-DESCRIPTOR
- which is used by SERVE-EVENT to gather the system identifier which is used
- to wait on input from the device.
-
- - ASDF:MAKE-BUILD admits a new type, :BINARY, which creates a standalone
- system (*.asd) accompanied by two binary files, statically linked library
- (.a or .lib), and a FASL (*.fasb). This can be used, to replace existing
- systems with precompiled ones.
+ which is used by SERVE-EVENT to gather the C file descriptor or Windows
+ handle used to wait on input from the device.
- ECL restores the habit of installing manual pages for ecl and ecl-config.
- LOAD now accepts the keyword argument :EXTERNAL-FORMAT
-ECL 10.3.1:
-===========
-
-This release has three important focuses: performance improvements in various
-fronts (garbage collection and hash tables), extending the run-process function
-and important fixes to let ECL work better with Slime. To quote one lisper
-ECL "this feels like a real Lisp implementation now"
-
-* Bugs fixed:
-
- - DIRECTORY used stat() also on files that did not match the directory masks.
-
- - The syntax for matching strings in DIRECTORY is now the same as in
- PATHNAME-MATCH-P. Formerly there were small differences, such as DIRECTORY
- understanding characters #\? and #\\ and PATHNAME-MATCH-P not.
-
- - Standalone executables do not require the existence of the ECLDIR directory
- to start up -- it may be required, though, for working Unicode because the
- encodings are stored there.
-
- - PROCESS-JOIN was exported from the wrong package.
-
- - PROCESS-JOIN failed when invoked with a thread that was in the process of
- being set up.
-
- - The output values of a process or thread are now collected in the process
- object and returned by PROCESS-JOIN.
-
- - ECL's interrupt servicing thread could not be shut down.
-
- - When compiling LET forms, ECL emitted warnings about removal of variables
- even when they were declared IGNORABLE.
-
- - An internal variable MP:*ALLOW-WITH-INTERRUPTS* was not declared special.
-
- - The compiler now understands function type proclamations with &OPTIONAL
- values.
-
- - The compiler now accepts THE special forms with a VALUES type.
-
- - If file A.lsp explicitely loads B.lsp to use a package that is only defined
- in B, then ECL signaled an error in the compiled version of A even after
- this one had required B.lsp.
-
- - ECL accepts FTYPE proclamations for SETF-functions.
-
- - On platforms where a stack overflow does not trigger a SIGSEGV, ECL was
- unable to recover from the overflow. Now it jumps to the outermost
- protection frame (typically the toplevel).
-
- - Socket streams are now two-way streams. This solves a problem with certain
- platforms (OS X) where a C stream can not be used to read and write
- simultaneously by two different threads.
-
- - TRUENAME and PROBE-FILE were not thread safe.
+* ASDF:
-* Visible changes:
-
- - Hash tables now use hand-coded specialized loops for EQ, EQL, EQUAL, EQUALP
- and package types, achieving a reduction of about 30% time in lookups.
-
- - A new function EXT:ENVIRON returns the list of strings that makes up the
- process environment. This is the equivalent of POSIX (char **environ)
- and Windows' GetEnvironmentStrings.
-
- - EXT:RUN-PROGRAM now accepts a keyword argument, :ENVIRON, with a list of
- strings used to configure the environment of the child process. For instance
- '("PWD=/home" "PATH=/usr/bin")
-
- - EXT:RUN-PROGRAM returns as third value an EXT:EXTERNAL-PROCESS structure,
- which supports the queries EXT:EXTERNAL-PROCESS-{PID,INPUT,OUTPUT,STATUS},
- following CCL's conventions.
-
- - The new function EXT:EXTERNAL-PROCESS-WAIT can be used to wait indefinitely
- for termination of a process or simply to query its status.
-
- - ECL implements a new garbage collector marking mode which at the overhead of
- one word per object achieves precise marking of heap objects, reducing
- accidental data retention and improving the time spent in garbage
- collection. This mode is only available when using --enable-boehm=system at
- configuration time.
-
- - ECL now ships with ASDF version 1.604
-
- - The variables C:*USER-CC-FLAGS* and C:*USER-LD-FLAGS* are lists of strings
- which can used to change the behavior of the C compiler and the
- linker. Note, however, that the flags that ECL uses may take priority.
-
- - In the C code we are beginning to use GCC's attributes (__attribute__) and
- branch annotation (__builtin_expect). This decreases the size of code that
- checks for errors and improves performance.
-
- - When printing compiler notes, instead of printing the macroexpanded form,
- ECL now prints the toplevel form, as follows
- ;;; Warning: in file src:lsp;autoload.lsp.NEWEST, position 1178 and top form
- ;;; (DEFMACRO WITH-COMPILATION-UNIT (OPTIONS &REST BODY) ...)
- ;;; The variable OPTIONS is not used.
-
- - ECL now implements EXT:*INVOKE-DEBUGGER-HOOK*, which works like *DEBUGGER-HOOK*
- but is also observed by BREAK. (SBCL extension adopted by ECL)
-
- - The UFFI interface now supports C99 types, such as :int8-t, :uint32-t, etc,
- but only when the corresponding types do exist in the underlying C environment.
-
- - SOCKET-MAKE-STREAM defaults :BUFFERING to :FULL and allows three new keyword
- arguments, :INPUT, :OUTPUT and :EXTERNAL-FORMAT, as in SBCL.
-
- - COMPILE-FILE admits the keyword argument :EXTERNAL-FORMAT.
+ - ECL's contributed modules and ECL's compiler can now be used in standalone
+ programs, for they are now stored both in FASL form and as statically linked
+ libraries.
- - A new function EXT:ALL-ENCODINGS lists all encondings known to ECL.
+ - ASDF:MAKE-BUILD takes a new keyword argument, :MOVE-HERE, that allows moving
+ the files that ASDF creates to the current directory. :MOVE-HERE can be the
+ boolean value T, in which case the files are output at ./asdf-output/ or a
+ pathname designator with the actual destination.
- - Improved readability of compiler messages.
-
- - SERVE-EVENT now allows time resolution of less than one second.
-
- - The PROFILE package now has an alias, SB-PROFILE.
-
- - ECL now stores the location of its source files in a logical hostname,
- "SRC:", which points to the directory where Announcement is located.
-
- - When building ECL, if "etags" is installed, a file TAGS is created which
- contains references to the location of all C functions. This file can be
- used to locate functions from the core library in Slime, using M-.
-
- - Documentation files now allow for annotation of arbitrary symbols,
- based on a key and a sub-key which are both symbols.
-
- - New function EXT:FUNCTION-LAMBDA-LIST which currently only works with
- functions from the core ECL library, generic functions and interpreted
- functions.
-
- - The debugger now is capable of showing the special variable bindings
- from a function, as well as the restarts newly bound by that function.
-
- - When using git, a new function EXT:LISP-IMPLEMENTATION-VCS-ID returns a
- unique identifier denoting the last commit. This can be used to discriminate
- between unstable releases and remove stale FASL files.
-
- - COMPILE-FILE admits two new keyword arguments, :SOURCE-TRUENAME and
- :SOURCE-OFFSET which can be used to change the value returned by
- EXT:COMPILED-FUNCTION-FILE when acting on compiled functions.
+ - ASDF:MAKE-BUILD admits a new type, :BINARY, which creates a standalone
+ system (*.asd) accompanied by two binary files, statically linked library
+ (.a or .lib), and a FASL (*.fasb). This can be used, to replace existing
+ systems with precompiled ones.
