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.
* 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.
- A new function EXT:ALL-ENCODINGS lists all encondings known to ECL.
- 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.

New in Chicken 4.4.0:
- the system can now be built with llvm-gcc and/or "clang" (the
LLVM C compiler which doesn't use the GNU C frontend)
- added new option `-trunk' to `chicken-install', which forces
building and installing the development version of extensions
in combination with `-t local'
- added new option `-deploy' to `chicken-install', which builds
extension for use in "deployed" applications (see below)
- added option `-deploy' to `csc', the compiler driver. With this
option `csc' can build fully self-contained application bundles
and double-clickable Macintosh GUI apps; see the "Deployment"
manual chapter for more information
- the directory given to the `-prefix' option of `chicken-install'
may now be a relative pathname.
- removed GUI-specific runtime library (`libchicken-gui') from
Windows build - GUI- and non-GUI applications now use the same
runtime library
- special forms of the foreign-function interface have been replaced
with an internal form and syntax to allow renaming and shadowing of
these forms
- the new `-private-repository' option in `csc' compiles executables
with the extension-repository path set to the directory from which
the program was started
- `csc': deprecated the `-W' and `-windows' options, added `-gui' as
a platform-independent replacement
- `require-extension'/`use' accepts now import-specifications
- user-defined extension-specifiers and `set-extension-specifier!'
have been removed
- `delete-file[*]', `rename-file', `create-directory', `file-copy',
`file-move', `delete-directory' and `change-directory' return their
argument/destination filename on success
- added the missing procedure `condition-variable-name' to the
srfi-18 library unit (Thanks to Joerg Wittenberger)
- the `glob?' function from the `regex' unit has been deprecated
- added the procedure `scan-input-lines' to the `utils' library unit
- added new runtime option `-:g' which enables GC debugging output
- reclamation of unused symbols in "symbol-gc" mode (`-:w') now only
takes place for symbols with an empty property-list
- on Windows loading of code compiled with [non-]GUI runtime libraries
will fail and produce an error message when the loading executable
is linked with a different runtime system
- on Windows, GUI libraries were not correctly linked by `csc'
- unit posix: added setter for `file-modification-time'
- the banner shows the branchname of the build, unless it's "master"
- the `-no-install' option to `chicken-install' is ignored when
building/installing dependencies
- `chicken-uninstall' takes a glob instead of a regular expression as
argument
- the rename and compare functions for low-level macro-definitions
accept now arbitrary s-expressions and renames/compares them recursively
- `number->string' handles negative-numbers with bases different from 10
correctly (thanks to Peter Danenberg)
- removed deprecated `setup-install-flag' and `setup-verbose-flag' from
the `setup-api' module
- added new option `-repository' to `chicken-install' (Thanks to Christian
Kellermann)
- removed `chicken-setup' stub program
- fix to `csc' to use the correct library when fixing dynamic load paths
(Thanks to Derrell Piper)
- removed html documentation from distribution (the wiki manual will
now be installed)
- fixed bug in `reexport' which caused syntax not to be correctly
reexported
- previous assignments to a toplevel variable that are separated by
side effect free expressions are removed
- fixed windows version of `find-files' (thanks to Jim Ursetto)
- documentation for extensions is not installed automatically by
`chicken-install' anymore
- changed binary version from "4" to "5", because the new runtime
libraries are not binary-compatible with previous releases; this
means all eggs have to be reinstalled and existing programs be
recompiled!
- added unboxing pass to compiler which results in partially dramatical
performance improvements for unsafe floating-point-intensive code;
unboxing is enabled on optimization levels 4 and 5
- removed rest-argument-vector optimization as it could conflict
with inlining (thanks to Sven Hartrumpf)
- renamed `pointer-offset' to `pointer+' and deprecated `pointer-offset'
- toplevel assignments that have no other side-effects can be eliminated
if it can be shown that the value is not used (the compiler will
generate a warning in this case)
- removed deprecated `-quiet' option in `chicken' program
- removed deprecated `run-time-macros' declaration
- removed deprecated `-v2' and `-v3' options in `csc' program
- removed deprecated `list-of' function (it is exclusively available
as `list-of?' now)
- removed deprecated `stat-...' functions in posix library unit
- removed deprecated `for-each-line' and `for-each-argv-line' procedures
in utils library unit
- added `fpinteger?' and `fpabs'
- deprecated `define-compiled-syntax'
- added new floating-point primitives `fpsin', `fpcos', `fptan',
`fpasin', `fpacos', `fpatan', `fpatan2', `fpexp', `fplog',
`fpexpt' and `fpsqrt'
- heavy cleanup of floating math functions which gives much better performance,
especially for code compiled in unsafe mode
- calling `assert' with a single argument shows the tested expression
on failure
- various bugfixes and cleaning up
1.) Work around lack of support for Sun Studio C Compiler and bugs
in this compiler (it crashes with "-O3", "-xO2" works fine).
2.) Use a hammer to disable MMX, AMD 3DNow and SSE support as Solaris
refuses to load libraries which contain unsupported instructions.

only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP
protocols, has a traceroute mode, the ability to send files between a
covered channel, and many other features.

Since ADSP has not yet been registered by IANA, adjust its method
label in Authentication-Results accordingly.
Include selector, domain and other text if possible when logging
key retrieval failures.
Add _FFR_SENDER_HEADERS, allowing user control over which header
fields are used to make the sign/verify decision and
perform key selection.
