What's New in Python 2.7.2?
===========================
*Release date: 2011-06-11*
Library
-------
- Issue #12009: Fixed regression in netrc file comment handling.
Extension Modules
-----------------
- Issue #1221: Make pyexpat.__version__ equal to the Python version.
What's New in Python 2.7.2 release candidate 1?
===============================================
*Release date: 2011-05-29*
Core and Builtins
-----------------
- Issue #9670: Increase the default stack size for secondary threads on
Mac OS X and FreeBSD to reduce the chances of a crash instead of a
"maximum recursion depth" RuntimeError exception.
(patch by Ronald Oussoren)
- Correct lookup of __dir__ on objects. This allows old-style classes to have
__dir__. It also causes errors besides AttributeError found on lookup to be
propagated.
- Issue #1195: Fix input() if it is interrupted by CTRL+d and then CTRL+c,
clear the end-of-file indicator after CTRL+d.
- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
(length bigger than 2^31-1 bytes).
- Issue #8651: Fix "z#" format of PyArg_Parse*() function: the size was not
written if PY_SSIZE_T_CLEAN is defined.
- Issue #9756: When calling a method descriptor or a slot wrapper descriptor,
the check of the object type doesn't read the __class__ attribute anymore.
Fix a crash if a class override its __class__ attribute (e.g. a proxy of the
str type). Patch written by Andreas Stührk.
- Issue #10517: After fork(), reinitialize the TLS used by the PyGILState_*
APIs, to avoid a crash with the pthread implementation in RHEL 5. Patch
by Charles-François Natali.
- Issue #6780: fix starts/endswith error message to mention that tuples are
accepted too.
- Issue #5057: fix a bug in the peepholer that led to non-portable pyc files
between narrow and wide builds while optimizing BINARY_SUBSCR on non-BMP
chars (e.g. u"\U00012345"[0]).
- Issue #11650: PyOS_StdioReadline() retries fgets() if it was interrupted
(EINTR), for example if the program is stopped with CTRL+z on Mac OS X. Patch
written by Charles-Francois Natali.
- Issue #11144: Ensure that int(a_float) returns an int whenever possible.
Previously, there were some corner cases where a long was returned even
though the result was within the range of an int.
- Issue #11450: Don't truncate hg version info in Py_GetBuildInfo() when
there are many tags (e.g. when using mq). Patch by Nadeem Vawda.
- Issue #10451: memoryview objects could allow to mutate a readable buffer.
Initial patch by Ross Lagerwall.
- Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a
class.
- Issue #8020: Avoid a crash where the small objects allocator would read
non-Python managed memory while it is being modified by another thread.
Patch by Matt Bandy.
- Issue #11004: Repaired edge case in deque.count().
- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
can now handle dates after 2038.
- Issue #4236: Py_InitModule4 now checks the import machinery directly
rather than the Py_IsInitialized flag, avoiding a Fatal Python
error in certain circumstances when an import is done in __del__.
- issue #11828: startswith and endswith don't accept None as slice index.
Patch by Torsten Becker.
- Issue #10674: Remove unused 'dictmaker' rule from grammar.
- Issue #10596: Fix float.__mod__ to have the same behaviour as
float.__divmod__ with respect to signed zeros. -4.0 % 4.0 should be
0.0, not -0.0.
- Issue #11386: bytearray.pop() now throws IndexError when the bytearray is
empty, instead of OverflowError.
Library
-------

- Issue #11236: getpass.getpass responds to ctrl-c or ctrl-z on terminal.
- Issue #11768: The signal handler of the signal module only calls

support enabled).
- Don't run pgen twice when using make -j.
- Issue #7716: Under Solaris, don't assume existence of /usr/xpg4/bin/grep in
the configure script but use $GREP instead. Patch by Fabian Groffen.

and DragonFly BSD. Patch by Nicolas Joly.
- Issue #10655: Fix the build on PowerPC on Linux with GCC when building with

changes in sbcl-1.0.49 relative to sbcl-1.0.48:
* minor incompatible change: WITH-LOCKED-HASH-TABLE no longer disables
interrupts for its body.
* enhancement: source locations are now available for files loaded as
source, compile-time-too evaluation, and initialization files.
* enhancement: WITH-COMPILATION-UNIT :SOURCE-NAMESTRING allows providing
virtual source-file information, eg. overriding input-file of COMPILE-FILE
when a temporary file is used for compilation.
* enhancement: ASDF has been updated to version 2.015.3.
* enhancement: backtraces involving frames from the default evaluator are
more readable.
* enhancement: RUN-PROGRAM works with user-defined binary input and output
streams.
* enhancement: more informative compile-time warnings and runtime errors for
type-errors detected at compile-time.
* enhancement: deadlock detection for mutexes and spinlocks.
* enhancement: dynamic-extent for &rest lists stack allocate only their
spines, not their argumets. While portable code should not rely on this,
particularly in combination with inlining, it should make dynamic-extent
easier to use safely.
* enhancement: SB-POSIX improvements:
** WNOHANG and WUNTRACED are exported.
** SYSCALL-ERROR now also provides the name of the failing system call.
* enhancement: --script improvements:
** errors on standard input, output, and error streams are handled and
cause scripts to exit silently, making them easier to use in shell
pipelines.
** backtraces from scripts now go to standard error instead of the
terminal even if one is available.
** --script can be an argument, causing the script to be loaded from
standard input.
* enhancement: MAKE-ALIEN-STRING provides an easy way to transport lisp
strings to foreign memory.
* enhancement: (SETF GC-LOGFILE) allows logging garbage collections to
a file, making it easier to understand heap dynamics.
* optimization: using a &REST argument only in APPLY or VALUES-LIST calls
allows the compiler to automatically elide rest-list allocation so long as
the call sites are in functions that the compiler knows cannot escape.
(lp#504575)
* optimization: CALL-NEXT-METHOD using explicit arguments is faster,
especially in safe code when none of the required arguments have changed
their identities.
* bug fix: blocking reads from FIFOs created by RUN-PROGRAM were
uninterruptible, as well as blocking reads from socket streams created
with for which :SERVE-EVENTS NIL. (regression from 1.0.42.43)
* bug fix: SET-SYNTAX-FROM-CHAR now removes dispatch-macro character syntax
from the to-char if the from-char is not a dispatch-macro character.
* bug fix: references to undefined variables in function calls that are
optimized away now signal a runtime error. (lp#722734)
* bug fix: miscompilation of MULTIPLE-VALUE-CALL when asserting derived
types from a function defined in the same file. (regression from
1.0.43.57)
* bug fix: TRULY-THE forms are now macroexpandable and setf-expandable.
(lp#771673)
* bug fix: spurious errors during QUIT when standard streams were closed.

Changes in 4.7.0
- Build system
- On BSD, libchicken.so is linked with -lpthread, as this seems
to be required for linking libraries that require pthreads
- The C header-files are now installed in a subdirectory below
the "PRFIX/include" directory to allow installation of multiple
chickens with different PROGRAM_PREFIX/PROGRAM_SUFFIX settings
in the same prefix; to avoid conflicts with existing CHICKEN
headers, it is recommended to completely remove any old
installation before installing the new version
- the PROGRAM_PREFIX and PROGRAM_SUFFIX configuration settings
are applied to generated files and directories which allows
perform differently named installations into the same PREFIX
- increaded binary-compatibility version from 5 to 6, which
means installed extensions in an existing installations will
have to be re-installed
- bugfixes in mingw/msys makefiles
- Sven Hartrumpf contributed a bugfix to the internal helper
script for creating distribution directories
- Peter Bex has cleaned up the makefiles heavily, making the
build more maintainable and easier to modify; thanks to all
who helped testing this new build
- renamed the makefile to `GNUmakefile' to catch using the
a make(3) other than GNU make
- configuration-header fix for BSD systems (thanks to Peter Bex
and Christian Kellermann)
- Core libraries

available as an extension which should be fully backwards-
compatible

sequences inside strings (thanks to Mario Domenech Goulart,
thanks to Kon Lovett for pointing out a missing test-file)
- The pretty printer did not escape some control characters correctly
(reported by Alan Post)
- control-characters in symbol-names are now properly escaped if
the symbol is printed readably (thanks to Alaric Snell-Pym
for pointing this out)
- the deprecated `random-seed' function has been removed
- "files" unit
- fixed bug in `normalize-pathname'
- `file-copy' and `file-move' check whether the source-file is a
directory

- pointer-vector-length
- pointer-vector-ref
- pointer-vector-set!
- "posix" unit
- "close-input-pipe" did not return the status code of a
terminated process on Windows (reported by Mario Domenech Goulart)
- added `file-creation-mode' (suggested by Mario Domenech Goulart)
- "setup-api" unit
- `required-extension-version' and `required-chicken-version' have
been deprecated
- "srfi-18" unit
- removed deprecated `milliseconds->time' and `time->milliseconds'
procedures
- `make-mutex' incorrectly created mutexes as initially owned by
the current threads (thanks to Joerg Wittenberger)

bindings which could result in toplevel assignments being
silently dropped (reported by Moritz Heidkamp)

must always be given when accumulated profiling is done
(thanks to Taylor Venable)

- intrinsic handling of `exact->inexact' and `string->number' is
now more efficient

block-mode
- fixed incorrect lambda-list check in scrutinizer (thanks to
Alan Post)
- Kon Lovett reported numerous bugs in the type-database used
by the scrutinizer
- `-fwrapv' is disabled on OpenBSD, since the default compiler
does not support this option (thanks to Christian Kellermann)
- on Solaris `gcc' is used by default, override `C_COMPILER'
to use the Sun compiler instead
- declaring a function `notinline' will prevent direct-call
optimization for known procedure calls
- the implementation of overflow-detection for arithmetic operations
on fixnums have been replaced and now allow using the full 63-bit
range of fixnums on 64-bit systems
- fixed serious inlining-bug (thanks to Sven Hartrumpf)
- constant-folding in the compiler has been simplified and
is more reliable (thanks to Sven Hartrumpf)
- optimization-levels 3 and higher imply `-unboxing -inline-global'
- added new declaration `unsafe-specialized-arithmetic' which allows
optimizing unboxed floating-point arithmetic in safe mode
- removed `scrutinize' declaration
- the warning shown when unimported identifiers are used in compiled
modules now also shows the name of the procedure where the
identifier is referenced (suggested by Alaric Snell-Pym)

Heidkamp)
- added the missing `unsigned-integer64' foreign type (thanks
to Moritz for catching this)

and provided a low-level API in the `lolevel' library unit for
manipulating pointer vectors
- Runtime system
- Fixed typo in "runtime.c" (thanks to Sven Hartrumpf)
- Little-endian detection on MIPS systems was not correct (thanks
to Christian Kellermann)
- Fixed bug in handling of runtime-options with arguments (also
reported by Christian Kellermann)
- `equal?' does not compare procedures recursively anymore
- fixed incorrect use of alloca.h on OpenBSD (thanks to
Christian Kellermann and Alan Post)
- checks for NaN and infinity are now done using ISO C99
operations, which required various changes to `chicken.h'
to make the code compile in ISO C99 mode
- remaining debris regarding MSVC builds has been removed
- fixed bug in argument-type check for 64-bit integer (thanks
to Kon Lovett)
- increased default trace-buffer size from 10 to 16
- fixed bug in low-level termination routine (thanks to
Jeronimo Pellegrini)
- the scheduler handles violations of internal invariants

- handled case where a global redefinition of `cons' influenced
a non-inlined internal use in the expander (thanks to David
Steiner)
- `define-record' now allows defining SRFI-17 setter procedures
for accessing slots
- the expansion of DSSSL lambda-lists uses now `let-optionals*'
internally instead of `let-optionals' and so allows
back-references to earlier formal variables; this also results in
faster and more compact code for argument-list destructuring
(thanks to Alan Post)
- new "implicit renaming" macro facility contributed by Peter Bex
(see `ir-macro-transformer')
- record-definitions are now made local to the module in which
they are defined (thanks to Jim Ursetto)
- parameters are now settable and can be modified using `set!'
(SRFI-17)
- added a SRFI-17 setter to `list-ref'
- added literal blob syntax ("#{ ... }")
- Tools

"-setup-mode" anymore to avoid problems with dynamic loading on
some platforms (specifically Mac OS X)
- option "-deploy" option did not copy the correct library
(including the version-number) (thanks to Christian Kellermann)
- added support for proxy-authentification (thanks to Iruata Souza)
- when installing from a local directory `chicken-install' now
removes existing `*.so' files in that location to avoid stale
binaries when the `make' syntax is used in setup scripts
- chicken-bug
- removed disabled e-mail support
- csc
- removed `-static-extension' option
- removed deprecated `-windows' option

in `-gui' mode (thanks to "ddp")
- when compiling in C++ mode, the compiler will be called with the
`-Wno-write-strings' option
- `-frwapv' has been added to the default C compiler options
- csi
- the ",m" toplevel command now accepts "#f" to switch back to
the initial empty module context (suggested by Christian Kellermann)
- fixed broken `,g' toplevel command
- deprecated `script' feature identifier (use `chicken-script'
instead)
- options `-p' and `-P' and `-e' imply `-no-init'
- the call-trace reported will not include exception-handler code
anymore (suggested by Christian Kellermann)

Update mawk to 1.3.4.20100625
Major changes in this release of mawk:
20100625
+ correct translation of octal and hex escapes for system regular
expression library.
+ modify configure script to support --program-suffix, etc.
+ add Debian package scripts, for "mawk-cur".
+ add RPM spec-file.
+ move release- and patch-level values from version.c to patchlev.h
to simplify packaging scripts.
20100618
+ correct translation of "^{" pattern for system regular expression
library (report by Elias Pipping).
+ fix sentence fragment in README (report by Elias Pipping).
20100507
+ cleanup gcc warnings for 64-bit platform, e.g., use size_t rather
than unsigned, etc.
+ fix warnings from clang --analyze
+ update/improve configure script
+ modify CF_GCC_VERSION to ignore stderr, e.g., from c89 alias
+ modify CF_GCC_WARNINGS, moving -W and -Wall into the list to check,
since c89 alias for gcc complains about these options.
+ add --disable-leaks and related options, for testing.
+ add lint rule to makefile.
+ add configure-check for ctags to work with pkgsrc.
+ amend change of array.w, fixes a regression in "delete" (report by
Heiner Marxen).
20100419
+ modify split() to handle embedded nulls in the string to split, e.g.,
BEGIN{s="a\0b"; print length(s); n = split(s,f,""); print n}
(report by Morris Lee).
+ modify array.w to update table pointers in the special case where
an array is known to have string-indices, but is later indexed via
integers. The problem occurs when the array grows large enough to
rehash it, e.g.,
BEGIN{a["n"];for(i=1;i<1000;++i)printf "%d\n", a[i]; }
(report by Morris Lee).
+ increase size of reference-count for strings to unsigned. It was an
unsigned short, which prevented using arrays larger than 64k, e.g.,
BEGIN{for(i = 1; i <= 65550; ++i){if(i >= 65534 && i<=65537) print i; s[i] = "a"}; delete s;}
(report by Morris Lee).
+ add special case for Solaris 10 (and up) to configure check
CF_XOPEN_SOURCE
+ refactored configure check CF_REGEX
20100224
+ add a configure check for large files (report by Sean Kumar).
+ modify check in collect_RE() to show the actual limit value, e.g.,
MIN_SPRINTF-2 used for built-in regular expressions.
+ increase MIN_SPRINTF, used as limit on regular-expression size, to
match the MAX_SPLIT value, i.e., slightly more than doubling the size
(report by Markus Gnam).
+ further modify makefile to build outside the source-tree.
+ modify makefile and mawktest to use relative path again, since the
existing script did not work with openSUSE's build (patch by Guido
Berhoerster).
+ fix makefile's .c.i rule, which lacked CPP definition.
+ update mawktest.bat script to more/less correspond with mawktest,
for Win32 console except where echo command does not handle the
required quoting syntax.
+ add vs6.mak, for Visual Studio 6.
+ modify mawktest script to report results from all tests, rather than
halting on the first failure.
+ add limit-check after processing match(test, "[^0-9A-Za-z]") to
ensure the internal trailing null of the test-string is not mistaken
for part of the string, i.e., RSTART, RLENGTH are computed correctly
(report by Markus Gnam).
+ modify parsing of -W option to use comma-separated values, e.g.,
"-Wi,e" for "-Winteractive" and "-Werror".
+ add timestamp to scancode.c, to help manage revisions.
+ improve configure macro CF_XOPEN_SOURCE, making it remove possibly
conflicting definitions before adding new ones.
+ update config.guess and config.sub
> patches by Jan Psota:
+ improve buffering for -Winteractive option.
+ allow multiple single-character flags after -W, e.g., "-Wie" for
"-Winteractive" and "-Werror" to permit these to be passed on a
"#"-line of a shell script, e.g.,
#!/usr/bin/mawk -Wie
> patches by Jonathan Nieder:
+ add new M_SAVE_POS and M_2JC operation codes (states) to the
built-in regular expression engine. Use these to reimplement
m* (closure), to provide a way to avoid infinite looping on
matches against empty strings. This change requires
reimplementing
the workaround for gawk's noloop1 testcase from 20090726.
+ improve buffer-overflow check for string_buff.
+ fix collect_RE to treat "[^]]" as a character class (meaning "not a
closing bracket") but "[^^]]" not as one. This also requires
initializing the local "start of character class" variable to NULL
rather than the beginning of the string, to avoid an invalid array
access when collecting expressions such as "^text".
+ within a character class and not followed by a :, ., or ~, a "[" is
just like any other character. This way, you can tell mawk to scan
for a literal [ character with "mawk /[[]/", and you can scan for a [
or ] with "mawk /[][]/". Also clean up the relevant loop in
do_class() to make it a bit more readable.
+ outside a character class, a "]" is just like any other character.
+ prevent do_class() from scanning past the end, e.g., if the
terminating zero byte was escaped.
+ fix regular-expression parsing when a right parenthesis ")" is
found without a preceding left parenthesis.
+ fix resetting of position stack when backtracking.
+ modify regular-expression engine to avoid exponential running time
for some regular expression matches in which the first match mawk
finds extends to the end of the string. This is a new fix for the
gawk noloop2 test, added here for regression testing.
