0.9.9
-----
New features:
- C++ struct declarations, 'new' operator, and del for C++ delete.
- As well as the 'not None' modifier for extension type arguments, there
is now 'or None' to explicitly allow passing None. It is planned to make
'not None' the default in a future version. For now, a warning is issued
(once per Pyrex run) if you do not specify one or the other.
- Extension types may have a 'nogc' option to suppress GC support.
Modifications:
- Exceptions caught by an except clause are no longer put into the thread
state and cannot be retrieved using sys.exc_info(). To access the caught
exception, it must be bound to a name in the except clause. A third name
can be supplied to capture the traceback.
- PyString_InternFromString is now exposed under the name 'cintern' because
it is not a complete substitute for 'intern' (it can't handle strings
containing null bytes). [John Arbash Meinel]
- Disabled size check for cimported types because it was generating too
many false positives in the field.
- Added __fastcall calling convention. Also no longer assuming that an
unspecified calling convention is the same as __cdecl.
- Operations between signed and unsigned ints of the same size now have
an unsigned result.
- Py_ssize_t now ranked between long and long long.
- Declaration of __new__ in an extension type is now an error, in
preparation for introducing new semantics.
- Added size_t type, and made sizeof() return it.
Bug fixes:
- When casting the result of a function call to a Python type, the
function could be called twice. [David Martinez]
- __Pyx_GetException was not taking account of the fact that the traceback
could be NULL.
- sizeof(module.typename) did not work. [Daniele Pianu]
changes in sbcl-1.0.38 relative to sbcl-1.0.37:
* incompatible change: Thread names are now restricted to SIMPLE-STRINGs
like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
* deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
* deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
SB-THREAD:GRAB-MUTEX.
* new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
contain additional data structures and tools for concurrent programming;
at the moment it contains a lock-free queue, and a lock-free mailbox
implementation.
* new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
GET-MUTEX but takes &key rather than &optional parameters. Also added
:TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
BSD.
* new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
SB-THREAD:WAIT-ON-SEMAPHORE.
* new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
SB-EXT:ATOMIC-INCF.
* new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
conditions to defer the deadline for forever.
* enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are
now bivalent.
* enhancement: errors from NO-APPLICABLE-METHOD and
NO-PRIMARY-METHOD now have a RETRY restart available to retry the
generic function call.
* enhancement: SB-BSD-SOCKET improvements
** sockets and socket streams now have a more informative printed
representation based on the corresponding SOCKET-NAME and
SOCKET-PEERNAME.
** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
(lp#540413)
** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
CL:CLOSE when appropriate, and no longer disassociates the stream
from the socket if close failed. (lp#543951)
* improvements to the instrumenting profiler
** new feature: report per-function GC overhead. (thanks to John Fremlin)
** optimization: counters no longer use locks for the overflow mode.
** bug fix: whenever a profiling counter wrapped into overflow mode, it
incurred an off-by-one miscount.
* enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
* enhancement: improved DEFMETHOD pretty-printing.
* enhancement: perform range reduction when arguments are too large for
x87's transcendentals (instead of returning 0). (lp#327192)
* enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
some of CL-PPCRE's macros. (lp#570079)
* enhancement: our machine code is slightly less hostile to valgrind on
x86-64.
* enhancement: up-to-date versions of NetBSD-current are supported. (Thanks
to Robert Swindells and Aleksej Saushev)
* bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
* bug fix: a rare case of startup-time page table corruption.
* bug fix: a semaphore with multiple waiters and some of them unwinding due
to timeouts could be left in an inconsistent state.
* bug fix: fix typo in "Reporting Bugs" section of the manual (lp#520366)
* bug fix: misoptimization of multiplication by one in
(SB-C::FLOAT-ACCURACY 0) policies.
* bug fix: miscounts in SB-PROFILE.
* bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
up itself" (March 2010) for further details.
* bug fix: allow forward FIND and POSITION on lists to elide checking :END
against length of the list if the element is found before the specified
END is reached. (thanks to Alec Berryman, lp#554385)
* bug fix: errors signalled during package graph modification no longer
block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
* bug fix: SB-POSIX build was broken when SBCL was compiled without the
:SB-DOC feature. (lp#552564)
* bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490)
* bug fix: more robust runtime executable path detection. (lp#375549)
* bug fix: GCD always returns positive values. (lp#413680)
* bug fix: Converting division to multiplication by reciprocal handles
denormals.
* bug fix: We were too eager in eliding range reduction tests on x87.
The maximal magnitude is 2^63, not 2^64.
* bug fix: Transforms for TRUNCATE don't die when the result is completely
ignored anymore.
* bug fix: Maybe restore buildability on Alpha.
* bug fix: READ-BYTE isn't inline anymore, fixing weird streams failures.
(lp#569404)
* bug fix: RANDOM-STATE can be printed readably again.
* bug fix: Unreadable objects were sometimes printed like #<\nFoo>.
* bug fix: Using EQL with non-constant values of constant type (e.g. EQL
types) could result in type mismatches during compilation.
changes in sbcl-1.0.37 relative to sbcl-1.0.36:
* enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
stack frame thrown from.
* enhancement: WITH-COMPILATION-UNIT :POLICY allows restricting changes to
compiler optimization qualities inside dynamic extent of its body.
* enhancement: LOAD-LOGICAL-PATHNAME-TRANSLATIONS can be used to load
translations from SYS:SITE;<HOST>.TRANSLATIONS.NEWEST (thanks to Michael
Weber)
* optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of
constraint propgation, allowing better compilation eg. when used to
access structures with WITH-SLOTS. (lp#520366)
* optimization: the compiler is now more aware of the type of the underlying
storage vector for multidimensional simple arrays resulting in better code
for accessing such arrays.
* optimization: passing NIL as the environment argument to TYPEP no longer
inhibits optimizing it. (lp#309788)
* optimization: more efficient register usage when handling single-float
arguments on x86-64. (thanks to Lutz Euler)
* optimization: ADJUST-ARRAY and STABLE-SORT on vectors no longer use
pre-allocated temporary vectors. (lp#496249)
* bug fix: Fix compiler error involving MAKE-ARRAY and IF forms
in :INITIAL-CONTENTS. (lp#523612)
* bug fix: FUNCTION-LAMBDA-EXPRESSION lost declarations from interpreted
functions. (lp#524707)
* bug fix: bogus style warnings from certain (SETF SLOT-VALUE) and
WITH-SLOTS usages during compilation.
* bug fix: SB-C::CLASS-INFO now prints correctly. (lp#514762)
* enhancement: Can now build with ud2 instead of int3 as trap instruction on
all x86oid platforms with :UD2-BREAKPOINTS target feature.
* bug fix: Breakpoints now work when using ud2 instead of int3 as trap
instruction (tested on x86oid linux with ud2-breakpoints).
* bug fix: slam.sh now works on win32.
* bug fix: better differences of numeric types. (lp#309124)
* bug fix: arrays declared intersection and union types can have their
upgraded element type derived. (lp#316078)
* bug fix: SB-SPROF allocation profiling for all threads failed to profile
threads started during profiling. (lp#472499)
* bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature.
(lp#535658)
* bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)
* bug fix: Comma inside a backquoted array or structure resulted in nonsense
values instead of signaling an error. (lp#309093)
* bug fix: Spurious unused variable warning in a DEFSTRUCT edge case.
(lp#528807)
* bug fix: More consistent warnings and notes for ignored DYNAMIC-EXTENT
declarations (lp#497321)
* bug fix: FIND and POSITION on lists did not check sequence bounds properly
and failed to detect circular lists (lp#452008)
* bug fix: leakage from ~/.asdf-install into the ASDf-INSTALL contrib build
(lp#538974)
* bug fix: LOOP OF-TYPE VECTOR compile-time error. (lp#540186)
* bug fix: SIGNAL SB-SYS:INTERACTIVE-INTERRUPT before entering the debugger
due to it, so that handlers can run.
* bug fix: reparsing undefined types if they have become defined since
parsing. (lp#309128)
* bug fix: missing &REST type in a proclamation for a function with both
&REST and &KEY in lambda-list caused miscompilation (lp#458354)
* bug fix: WHO-CALLS information for source-transformed and compiler-macro
expanded calls (lp#542174)
* bug fix: more accurate WHO-MACROEXPANDS information; point into rather
than just at toplevel form.
Apply some openbsd changes from openbsd ports.

Changelog:
20091220
+ bump version to 1.3.4
+ update INSTALL and README files.
+ improve configure checks for math library.
+ change test for NaN to use sqrt() rather than log() to work around
cygwin's partly broken math functions.
+ add/use isnanf() to work around other breakage in cygwin math
functions.

proper function pointer for sigaction, e.g., on Tru64.
+ add check for sigaction function pointer, whose POSIX form is
absent from the cygwin header.
+ extend MAWKBINMODE, adding a third bit which when set will suppress
the change for RS or ORS to use CR/LF rather than LF. This is used
for MinGW to make the "check" rule in a build work, for instance.

for MinGW where these are absent.
+ add runtime check for floating-point underflow exceptions
+ fix an old 1.3.3 bug in re_split(), which did not check properly for
the end of buffer; this broke on Tru64.

Setting PHP_VERSION_DEFAULT as "5" or "53" to select PHP 5.2.x or 5.3.x.
PHP is an HTML-embedded scripting language. It is modular, with
some object-oriented features. Much of its syntax is borrowed from
C, Java and Perl with a couple of unique PHP-specific features
thrown in. The language is designed to allow web developers to
write dynamically generated pages quickly.
* Add "53" as PHP 5.3.x for several PHP_VERSION_* and its frends.
* Add PKG_PHP_MAJOR_VERS which currently only takes "5".
* Add "php53" to PHP_PKG_PREFIX.
* Add checking installed PHP's version against required version.

The GNU project and the GCC developers are pleased to announce the
release of GCC 4.4.3.
This release is a bug-fix release, containing fixes for regressions in
GCC 4.4.1 relative to previous releases of GCC.
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'

- 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
New in version 1.0.36
- new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and
SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND
counterparts but work on type specifiers.
- new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a
symbol is known to name a type specifier.
- new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a
given type specifier is valid where "valid" basically means
"would be accepted as second argument of TYPEP".
- new feature: SB-INTROSPECT:FUNCTION-TYPE takes a
function-designator and returns the function's declared, or
derived FTYPE.
- new feature: SB-POSIX now supports accessing the d_ino
member of dirent structures. (Thanks to Philipp Marek and
Pierre THEIRRY)
- new feature: The function SB-EXT:SEED-RANDOM-STATE has been
added to provide for seeding a RANDOM-STATE object with
user-provided data or from the operating system's PRNG.
Also, (MAKE-RANDOM-STATE T) will attempt to initialize the
returned state from the operating system's PRNG where
possible. (Thanks to Fare Rideau; launchpad bug #310116)
- bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set
the FILE-POSITION of the stream being read from. (launchpad

Larry Valkama and Bruce O'Neel.
- bug fix: SB-THREAD:CONDITION-WAIT sometimes signaled a
deadline twice in a row even though a handler defered the
deadline long into the future. (#512914)
- bug fix: A deadline handler was run without interrupts
enabled for a deadline signaled within
SB-THREAD:CONDITION-WAIT.
That could result in infinitely spinning, non-killable threads.
- bug fix: Backtrace from internal-errors on x86-64 os x was
truncated before reaching the erring stack frame.
- bug fix: Fix type derivation for EXPT when raising a fixnum
to a real power. (launchpad bug #525949)

News
changes in sbcl-1.0.35 relative to sbcl-1.0.34:
* optimization: ROUND with a single single-float or double-float argument
is properly inlined when possible.
* optimization: Slightly better code is generated for integer<->float
conversions and for single-float<->double-float conversions on x86-64.
* optimization: SB-ROTATE-BYTE:ROTATE-BYTE now generates more efficient
code for 32-bit and 64-bit rotations on x86-64.
* bug fix: The install script changes the ownership of directories as well
as files for contrib modules using asdf. (thanks to Eugene Ossintsev;
launchpad bug lp#508485)
* bug fix: TRUNCATE with a single single-float or double-float argument is
properly inlined when possible. (launchpad bug lp#489388)
* bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE
no longer causes a compiler error on x86 and ppc.
* bug fix: GET-MACRO-CHARACTER bogusly computed its second return value
always relative to *READTABLE* rather than the passed argument.
changes in sbcl-1.0.34 relative to sbcl-1.0.33:
* minor incompatible change: threading support is now enabled by default
on x86[-64] Linux.
* enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most
builtin types.
* enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN)
are now caught and reported just like errors during macroexpansion.
* enhancement: SB-POSIX now provides access to tcdrain(), tcflow(),
tcflush(), tcgetsid(), and tcsendbreak(). (thanks to Jerry James)
* enhancement: ASDF systems can now depends on SB-QUEUE.
* fixes and improvements related to Unicode and external formats:
** bug fix: error handling and restart usage in the ucs-2 external format
has been improved.
** there is now an implementation of the ucs-4 external format.
** the utf-16 and utf-32 external formats are supported.
* bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings
in the environment. setenv() and unsetenv() are also provided. (reported by
Fare Rideau; launchpad bug lp#460455)
* bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style
loading. This ensures sensible errors for .FASL files from other
implementations on case-insensitive filesystems. (reported by Willem
Broekema; launchpad bug lp#489417)
* bug fix: #p"\\\\" can now be read without error on Win32. (reported by
Willem Broekema; launchpad bug lp#489698).
* bug fix: some minor code rearrangements to reenable warning-free building
from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104)
* bug fix: PRINT-OBJECT for clos instances respects the right margin when
pretty printing
* bug fix: FIND-PACKAGE & DEFPACKAGE were not thread safe. (reported by
Attila Lendvai)
changes in sbcl-1.0.33 relative to sbcl-1.0.32:
* new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent)
* improvement: support O_LARGEFILE access to files larger than 2GB on
x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#453080)
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of
definitions for methods specializing on the passed class itself.
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of
definitions for methods specializing on the passed class itself, or on
subclasses of it.
* new build flag: :sb-xref-for-internals; SBCL will collect xref information
about itself during the build (e.g. for M-? in Slime), if this flag is
enabled in customize-target-features.lisp. This will increase the core
size by about 5-6mb, though, so it's mostly interesting to SBCL
developers.
* new feature: various GENCGC tuning parameters have been experimentally
documented and exported from SB-EXT. See documentation for details.
* fixes and improvements related to Unicode and external formats:
** the Unicode character database has been upgraded to the
Unicode 5.2 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** improvement: restarts for providing replacement input/output on coding
errors for fd-stream external formats.
** improvement: where :<encoding> is a keyword corresponding to an
external format the system supports, it is now possible to specify
(:<encoding> :replacement <character>) as an external format which will
automatically substitute <character> on encoding or decoding errors for
streams and for STRING-TO-OCTETS and its inverse. (launchpad bug
lp#317072)
** improvement: the file streams underlying the standard streams (such as
*STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format
which uses the replacement mechanism to handle encoding errors,
preventing various infinite error chains and unrecoverable I/O
confusion.
** minor incompatible change: the utf-8 external format now correctly
refuses to encode Lisp characters in the surrogate range (char-codes
between #xd800 and #xdfff).
** fix a typo preventing conversion of strings into octet vectors
in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug
lp#471689)
** fix a bug in the octet multibyte handling of decoding errors and the
USE-VALUE restart. (launchpad bug lp#314939)
** fix the bug underlying the expected failure in the FORCE-END-OF-FILE
restart on fd-stream decoding errors.
** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the
error is near the end of file.
** fix a double-error case in unibyte octet conversions, when the first
use of USE-VALUE is ignored.
** fix bugs in handling of undefined code points in unibyte encodings.
** fix LISTEN (and consequent hangs in READ-CHAR-NO-HANG) on bivalent
streams after an UNREAD-CHAR.
* enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
object is allocated in a boxed region of dynamic space.
* enhancement: SB-POSIX:FORK now signals an error if an attempt to
fork with multiple Lisp threads running is made, instead of going
ahead with unpredictable consequences. (reported by Leslie Polzer)
* bug fix: uses of slot accessors on specialized method parameters within
the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type
error while finalizing the class. This fix may cause classes with slot
accessors to be finalized later than previously. (reported by Lars Rune
Nøstdal; launchpad bug lp#473699)
* bug fix: restore buildability on the MIPS platform. (regression from
1.0.30.38, reported by Samium Gromoff)
* bug fix: inspecting closures is less likely to fail with a type error.
* bug fix: no timer starvation when setting the system clock back.
(launchpad bug lp#460283)
* bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the
standard pprint dispatch table as specified by CLHS.
* bug fix: give CLISP a hint about a type declaration to enable it to build
the cross-compiler without warnings. (thanks to Josh Elasser; launchpad
bug lp#396597)
* bug fix: correctly dump literal objects in defaulting forms of arglists.
(reported by Attila Lendvai; launchpad bug lp#310132)
* bug fix: distinguish in type specifiers between arrays that might be
complex and arrays that are definitely complex. (launchpad bug lp#309129)
* bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD
type. (reported by Levente Mészáros; launchpad bug lp#485972)
* bug fix: setting the value of a symbol-macro within a method in the
presence of type declarations works properly again. (reported by Iban
Hatchondo; launchpad bug lp#485019)
changes in sbcl-1.0.32 relative to sbcl-1.0.31:
* optimization: faster FIND and POSITION on strings of unknown element type
in high SPEED policies. (thanks to Karol Swietlicki)
* optimization: faster CONCATENATE 'STRING in low SPEED policies (reported
by David Vázquez)
* improvement: better error signalling for bogus parameter specializer names
in DEFMETHOD forms (reported by Pluijzer)
* bug fix: DELETE-FILE once again works on logical pathnames (regression
since 1.0.30.49)
* bug fix: LOGICAL-PATHNAME signals a TYPE-ERROR if pathspec is specified
incorrectly.
* bug fix: redefinition of a class via DEFCLASS without :DEFAULT-INITARGS
removes previous default initargs (reported by Lars Rune Nøstdal and
Samium Gromoff)
* bug fix: correct WHO-CALLS information for inlined lambdas with complex
lambda-lists. (reported by Peter Seibel)
* bug fix: SAVE-LISP-AND-DIE option :SAVE-RUNTIME-OPTIONS did not work
correctly when starting from an executable core without saved runtime
options (reported by Faré Rideau, thanks to Zach Beane)
* bug fix: (SETF SLOT-VALUE) signalled a warning which should have been
an optimization note instead. (reported by Martin Cracauer)
* bug fix: WITH-SLOTS did not work with THE forms. (thanks to David Tolpin)
* bug fix: Have RUN-PROGRAM with :INPUT T only run the subprocess in a
new process group if it doesn't need to share stdin with the sbcl
process. (thanks to Leslie Polzer)
* bug fix: SATISFIES could be misoptimized to refer to a local function.
(reported by Stanislaw Halik)
changes in sbcl-1.0.31 relative to sbcl-1.0.30:
* improvement: stack allocation is should now be possible in all nested
inlining cases: failure to stack allocate when equivalent code is manually
open coded is now considered a bug.
* improvements related to Unicode:
** the Unicode character database has been upgraded to the
Unicode 5.1 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** the system now recognizes and produces names for Unicode Hangul
syllable characters.
** the EBCDIC-US external-format is now supported for octet operations
(as well as for stream operations).
* new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
be used to output toplevel compile-time effects into a separate .CFASL
file.
* optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion is
actually needed.
* optimization: TRUNCATE on known single- and double-floats is upto 25%
faster.
* optimization: division of floating point numbers by constants uses
multiplication by reciprocal when an exact reciprocal exists.
* optimization: multiplication of single- and double-floats floats by
constant two has been optimized.
* optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
sufficient type information is available. (thanks to Leslie Polzer)
* optimization: SLOT-VALUE and (SETF SLOT-VALUE) with constant slot names on
known structure objects are as efficient as defstruct generated accessors.
* optimization: unused vector creation can now be optimized away.
* improvement: ASDF systems can now depends on SB-INTROSPECT.
* improvement: a STYLE-WARNING is signalled when a generic function
clobbers an earlier FTYPE proclamation.
* improvement: the compiler is able to track the effective type of
generic function across method addition and removal even in the
absence of an explicit DEFGENERIC.
* improvement: DESCRIBE now reports on symbols naming undefined
but assumed or declared function as well.
* improvement: recompilation of systems using SB-GROVEL now works
(thanks to Leslie Polzer)
* improvements to SB-CLTL2 (thanks to Larry D'Anna):
** functions DECLARATION-INFORMATION, PARSE-MACRO, and ENCLOSE have been
documented.
** AUGMENT-ENVIRONMENT and DEFINE-DECLARATION have been implemented.
** DECLARATION-INFORMATION now supports declaration name DECLARATION as
well as user defined declaration names.
** VARIABLE-INFORMATION is now aware of alien variables.
* improvement: improved address space layout on OpenBSD (thanks to Josh
Elsasser)
* improvement: pretty-printing of various Lisp forms has been improved
(thanks to Tobias Rittweiler)
* bug fix: calls to DECODE-FLOAT and INTEGER-DECODE-FLOAT whose value was
unused were deleted in safe code. (reported by John Fremlin)

Stelian Ionescu)
* bug fix: a failing AVER in CONVERT-MV-CALL has been fixed. (thanks to
Larry D'Anna)

(thanks to Larry D'Anna)
* bug fix: SLEEP supports times over 100 million seconds on long on OpenBSD
as well. (reported by Josh Elsasser)
* bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT T,
leading to possible attempts to delete the same file twice. See docstring
on DELETE-FILE for details. (reported by John Fremlin)
* bug fix: DELETE-FILE once again deletes the file named by the pathname
designator argument, rather than its truename. (reported by Luis
Oliveira)
* bug fix: the low-level debugger had 32-bit assumptions and was missing
information about some array types. (thanks to Luis Oliveira)
* bug fix: moderately complex combinations of inline expansions could
be miscompiled if the result was declared to be dynamic extent.
* bug fix: on x86, SAP-REF of sizes greater than 8 bits with offsets of the
form (+ <variable> <integer>) were miscompiled under certain
circumstances.
* bug fix: in some cases no compiler note about failure to stack allocate
was emitted, even if the objects were in fact heap allocated.
* bug fix: minor violation of "otherwise inaccessible" rule for stack
allocation could cause objects users might reasonably expect to
be heap allocated to be stack allocated.
* bug fix: DESCRIBE signalled an error for generic functions under
certain circumstances. (thanks to Leslie Polzer)
* bug fix: Fixed spelling of an error message.

it on NetBSD. I can't explain the behavior on DragonFly, but the use of
the mono linker in the Makefiles matching the source, so the problem is
elsewhere.
I was trying to solve here, but the new libtool doesn't like being
used like this, and it doesn't seem to be needed.
Fixes failure observed in bulk build.
XXX there's still a PLIST problem:
ERROR: The following files are in the PLIST but not in /usr/pkg:
ERROR: /usr/pkg/lib/gauche/0.9/x86_64--netbsd/gauche--threads.so
ERROR: /usr/pkg/share/gauche/0.9/lib/gauche/threads.scm
w/o "-l", yylinelo still gets defined in recent versions, but not
in the version which comes with NetBSD-4.
So require "flex" for the build and always use the "-l" flag, so we'll

don't let the hints file add new libraries that may be found outside Pkgsrc
control.
Fixes build on Gentoo system, and possibly other Linux systems too that might
have stray -lgdbm_compat libraries lying around. This reverts hints/linux.sh
to look more like it did in 5.10.0.
This makes f2c work. Bump PKGREVISION.
The default CPP points to gcc, which broke f2c because gcc is unable to
preprocess Fortran files as the Fortran compiler is not installed.
Surprisingly, /usr/bin/cpp is just a wrapper around gcc, but it explicitly
passes '-x c' to cpp to force the language to be C and bypass the .F
extension.
Update OK'ed by agc@
Pkgsrc changes:
o Replace perl and parrot interpreter references where we can
(one perl module not available at pre-configure time not done)
o Remove patches which are no longer necessary, since they either
came from upstream or have been adopted there
o Update the PLIST to sync with what's being installed
Upstream changes:
- Functionality
+ The FileHandle PMC now exposes the exit code of child process
that was run as pipe.
+ Experimental support for overriding VTABLE invoke in PIR objects
was added.
+ The method 'type' was added to the PackfileAnnotations PMC.
+ The internals of the parrot calling conventions, PCC, were
reworked. All call paths now use a CallSignature object for
passing arguments and return values.
+ The new API-function 'Parrot_ext_call' was added for calling
into C-land.
+ The fixed-size allocator was improved.
+ The files installed by 'make install-dev' are now covered by
'make install' as well.
+ The experimental ops 'fetch' and 'vivify' were added.
+ The -I option to the command 'parrot' now prepends items to
the search path.
+ The Context struct was substituted with auto attributes
(context_auto_attrs branch).
+ Use the osname determined in auto::arch in subsequent configuration
steps (convert_OSNAME branch).
+ Eliminated dependence on Perl 5 '%Config' in auto::format
(auto_format_no_Config branch).
+ MultiSub PMCs now stringify to the name of their first candidate,
instead of the number of candidates.
+ The platform detection at the start of the configuration process
was improved.
+ The 'lineof' method on CodeString objects now precomputes line
number information to be more efficient on variable-width
encoded strings.
+ P6object now supports .WHO and .WHERE methods on protoobjects.
- Compilers
+ A shiny new self-hosting implementation of NQP has been added
in ext/nqp-rx.
- New NQP available as nqp-rx.pbc or parrot-nqp fakecutable.
- NQP includes direct support for grammars and regexes, including
protoregexes.
- NQP has a new PAST-based regex engine (intended to replace PGE).
- Regexes may contain code assertions, parameters, lexical
declarations, and more.
- Double-quoted strings now interpolate scalar variables and closures.
- Subroutine declarations are now lexical by default.
+ PCT
- PAST::Block now supports an 'nsentry' attribute.
- PAST::Var allows 'contextual' scope.
- Attribute bindings now return the bound value.
- Platforms
+ Fixes for the port of Parrot to RTEMS were applied. Yay, first
port to a real time OS!
+ On NetBSD, shared libs are now used.
- Performance
+ Use the the fixed-sized allocator in the Context and the
CallSignature PMC.
+ Many small speed improvements.
- New deprecations
+ MT19937, the Mersenne twisted pseudorandom number generator,
is now hosted on github and will be removed from the Parrot
core. (eligible in 2.1)
+ The 'Parrot_call_*' functions for invoking a sub/method object from C are
deprecated. They are replaced by 'Parrot_ext_call'. (eligible in 2.1)
+ All bitwise VTABLE functions are deprecated. (eligible in 2.1)
+ All bitwise ops will become dynops. (eligible in 2.1)
- Realized deprecations
+ The slice VTABLE entry was removed.
+ The last traces of the 'malloc' garbage collector were removed.
+ Parrot_pcc_constants() was renamed to Parrot_pcc_get_constants().
+ The deprecated functions from the Embedding/Extension interface
were removed.
+ The library YAML/Parser/Syck.pir was removed.
+ The VTABLE function instantiate_str() was removed.
+ Building of parrot_nqp was removed.
- Tests
+ The test coverage of the time-related ops was much improved.
+ New testing functions in Test::More: lives_ok() and dies_ok().
+ The Perl 5 based test scripts t/op/bitwist.t, t/op/comp.t,
t/op/inf_nan.t, t/op/literal.t, t/op/number.t, t/op/sprintf2.t,
and t/op/00ff-dos.t were converted to PIR.
+ The test scripts t/op/annotate.t and t/op/time.t have begun
to be translated from Perl 5 to PIR.
+ In some tests the dependency on %Config from Perl 5 was eliminated.
- Documentation
+ The meaning of 'p' means in NCI function call signatures was clarified.
- Tools
+ The stub for a new language, as created by mk_language_shell.pl,
now relies on the PIR-based tools, which are replacing the Perl
5-based tools.
+ The library Configure.pir was added.
+ The library distutils.pir was added.
- Miscellaneous
+ The mailing list parrot-users and a corresponding google group was created,
http://groups.google.com/group/parrot-users.
+ Many bugfixes, code cleanups, and coding standard fixes.

ECL 9.12.3:
===========
* Visible changes:
- When converting rationals to floats, ECL now rounds instead of using the
routine in GMP, which truncates.
- LOAD open streams in buffered mode. It does not cause any significant
performance increase except in broken network filesystems that lack
buffering such as some implementations of NFS.
ECL 9.12.2:
===========
* Bugs fixed:
- RANDOM broken on 64-bits architectures.
- The debugger now shows the package names of inspected variables.
- The code in CLX that dealt with interrupts had become outdated.
* Other changes:
- Methods now show up in the debugger with their original name.
- Enlarged the string buffers used for reading and parsing lisp data.
ECL 9.12.1:
===========
* Platform support:
- Support for Itanium.
- Support for Solaris and SunStudio compiler.
- Support for Microsoft Visual Studio C++ 10 beta.
- Support for Cygwin.
* Visible changes:
- New function EXT:ARRAY-RAW-DATA returns a non-adjustable vector of type
(UNSIGNED-BYTE 8) with the content of an array. The returned array overlaps
with the original, so any change on one will affect the other.
- LOAD works on special files (/dev/null and the like).
- New command line option --version outputs the version number preceded
by the implementation name ("ECL 9.11.1" in this particular release).
- MULTIPLE-VALUE-BIND is optimally replaced with a LET form when the number
of variables is 1.
- ECL now accepts Windows' UNC pathnames.
(with-open-file (s #P"//JUANJO-IMAC/Public Folder/index.html"
:direction :input)
(loop for l = (read-line s nil nil)
while l
do (princ l)))
- The default memory limits are increased up to 512Mb for 32 bit images and
4Gb for 64-bits systems.
- The bignums generated by RANDOM did not contain enough random bits.
* Bugs fixed:
- In single-threaded builds, ECL did not properly restore the signal mask
before jumping out of a signal handler.
- Floating point exceptions were sometimes ignored, leading to infinite loops.
- A new configuration flag is added, --with-dffi. This flag allows
deactivating the foreign function interface when the compiler does not
support inline assembly with the GCC syntax and libffi is not available.
- In a multithreaded ECL, when handling a Ctr-C/SIGINT asynchronous interrupt,
the CONTINUE restart was not always available.
- In cygwin, LOAD was unable to load and execute binary files.
- In cygwin, FASL files can not lack a file extension, because dlopen()
then looks for a file ending in ".dll" and fails.
- In cygwin, files that are dlopen'ed must have executable permissions.
- ECL ignored the IGNORABLE declaration.
- The IGNORE/IGNORABLE declarations accept (but ignore) arguments of the
for (FUNCTION function-name).
- SUBTYPEP caused a SIGSEGV when the input was a not finalized class.
- Due to the SUBTYPEP bug, ECL could not compile DEFMETHOD forms whose
arguments referenced non-finalized classes
- When supplied an error value, (EXT:SAFE-EVAL form env &optional err-value)
never returned the output of the evaluated form.
- FIND-SYMBOL accepted string designators instead of just strings, as
mandated by the ANSI specification.
- APPEND copied also the last argument.
- (LOG #C(x x)) now produces a better result when x == 0
- (ATAN #C(0.0 1.0)) no longer produces an infinite recursion.
- Solved a hard to hit bug in DEFCLASS's routine for detecting collisions in
slot names
- LOG and LOG1P did not work properly with NaNs under linux.
- ECL had problems combining #. and #n=/#n# reader macros.
- FDEFINITION and SYMBOL-FUNCTION caused an incorrect error condition when
acting on NIL.
- The optimizer for TYPEP did not work when passed three arguments.
* Clos:
- CLOS:SET-FUNCALLABLE-INSTANCE-FUNCTION broke the value if SI:INSTANCE-SIG,
preventing any further access to the instance slots.
- The optimized slot accessors check that the instances are up to date.
- The use of MAKE-INSTANCES-OBSOLETE now forces UPDATE-INSTANCE-FOR-REDEFINED-CLASS
to be invoked even if the slots did not change.
- ENSURE-GENERIC-FUNCTION-USING-CLASS does not provide a default method class.
* Sockets:
- The socket option TCP_NODELAY option has been fixed: it was improperly using
the socket interface SOL_SOCKET instead of IPPROTO_TCP (Chun Tian)
- sockopt-linger and (setf sockopt-linger) now work as they should, using
the struct linger argument (M. Mondor)
* ASDF:
- ASDF:MAKE-BUILD now accepts also a :PROLOGUE-CODE argument with code to
be executed before all lisp files are run.
- C:BUILDER's argument :PROLOGUE-CODE can now be a lisp form. In the case of
standalone programs the prologue code is always executed after cl_boot() has
been invoked.
- QUIT did not work from standalone executables created with neither ASDF
nor with C:BUILDER.
Patch provided by Peter Bex.
Changes in 4.3.0:
- removed tracing facility and apply-hook (see the "trace" egg
for a replacement for tracing and breakpoints)
- chicken-install(1): renamed `-host-extension' option to `-host'
- added support for a make(1) configuration file ("config.make")
- `chicken-install' now allows specifiying a proxy for retrieving
extensions over HTTP (thanks to Nicolas Pelletier)
- fixed bug in `cond-expand' that incorrectly renamed feature-identifiers
if the form was the product of a syntax expansion (reported by Thomas
Bushnell)
- import-libraries are only generated by the compiler if they don't exist
yet and if the content has actually changed (this simplifies makefile-
rules in some cases)
- it is now possible to pass a config-file to `make(1)' instead of specifying
all build-options as variables on the command-line (see README)
- removed compiler options for "benchmark-mode" and replaced them with a
new optimization level (5) (note that `-O5' does not imply fixnum mode
anymore)
- `hen.el' and `scheme-complete.el' are not bundled with the core system
anymore - `hen.el' is currently not maintained, and `scheme-complete.el'
has its own release cycle; both files are available, see
http://chicken.wiki.br/emacs
- removed meaningless benchmark suite and cleaned up
- added optional argument to `grep' that allows applying a function
to each matched item (contributed by Tony Sidaway)
- added extension-property `import-only', which makes it possible to
create extensions that have no runtime part
- the argument to `seconds->string', `seconds->utc-time' and
`seconds->local-time' is now optional and defaults to the value
of `(current-seconds)' (suggested by Mario Goulart)
- removed read-syntax for `syntax' form
- fixed bug in `get-condition-property'
- fixed bug in windows version of `process-execute'
- TCP timeouts throw exception of kind `timeout' to allow
distinguishing between timeouts and other errors
- removed some internal functions that manipulate environments
- fixed bugs in `standard-extension' (`setup-api' module) and added keyword
arguments for building static extensions and adding custom properties
- when cross-compiling, `chicken-install(1)' doesn't pass `-setup-mode'
(the host tools should not attempt to load target binaries)
- `installation-prefix' in the `setup-api' module was not always correctly
set
- the `-force' option in `chicken-install(1)' overrides the CHICKEN version
check
- disabled e-mail feature in `chicken-bug(1)', since it doesn't work
anyway, in the moment
- fixed bug in `reexport' that made it impossible to reexport core library
definitions
- fix in optimizer that sometimes caused C functions for inlined
procedures to be emitted multiple times (Thanks to Joerg Wittenberger)
- documented `define-compiler-syntax' and `let-compiler-syntax'
- printer for hash-tables shows current number of stores items
- when upgrading during installation of a dependency `chicken-install'
shows the version to upgrade to (Thanks to Christian Kellermann)
- Updated scheme-complete (Thanks to Alex Shinn)
- fix for pathnames with whitespace in 'runtests.sh' on Windows
- fix for 'normalize-pathname' with absolute pathname argument
- added 'decompose-directory' to unit files
- fix for 'local-timezone-abbreviation' - wasn't using the current time
so tz-name constant
- deprecated 'make-pathname' separator argument
SunOS, Java and ODBC support by Filip Hajny
and some tests by Matthias Kretschmer.

Pkgsrc changes:
- Adjust some patches
- Remove patches integrated upstream
Upstream changes:
"5.10.1 is a maintenance release for perl 5.10, incorporating various
minor bugfixes and optimisations."
Nonetheless some incompatibles changes are noteworthy and are related
to:
- flip-flop and defined-or operators behavior in switch statement
- type-based dispatch and overloading of the smart match operator
- 'use feature :5.10*' semantics
- Perl development switched to git
- internal structure of the ext/ perl source directory changed
- removal of the modules Test::Harness::Straps, ExtUtils::MakeMaker::bytes
and ExtUtils::MakeMaker::vmsish
- the Module::CoreList module no longer contains the %:patchlevel hash
- a bugfix related to the handling of the /m modifier and qr resulted
in a change of behaviour between 5.8.x and 5.10.0 (this was missing from
perl 5.10.0 perldelta).
For a complete list of changes see included perl5101delta(1) or
http://perldoc.perl.org/perl5101delta.html
Major New Features
- Addition of IDE interface support.
- Changes to pretty-printing and equality. These are now inherited
across module boundaries. Addition of PolyML.addPrettyPrinter
to install a new-style pretty printer.

of unreferenced identifiers.
- Added breakEx and clearEx to debugger functions.
These enter the debugger when the code raises a given exception.
- Improvement to resonsiveness to pipes especially in Windows.
