XXX check that regsub.split / splitx are correctly documented.
|
||||
|
||||
======================================
|
||||
==> Release 1.4 (sometime 3Q 1996) <==
|
||||
==> Release 1.4beta3 (August 26 1996) <==
|
||||
======================================
|
||||
|
||||
|
||||
What's new since 1.4 beta 1?
|
||||
----------------------------
|
||||
XXX This needs to be reordered.
|
||||
|
||||
What's new in 1.4beta3 (since beta2)?
|
||||
-------------------------------------
|
||||
|
||||
- New module whichdb recognizes dbm, gdbm and bsddb/dbhash files.
|
||||
|
||||
- The Doc/Makefile targets have been reorganized somewhat to remove the
|
||||
insistence on always generating PostScript.
|
||||
|
||||
- The texinfo to html filter (Doc/texi2html.py) has been improved somewhat.
|
||||
|
||||
- "errors.h" has been renamed to "pyerrors.h" to resolve a long-standing
|
||||
name conflict on the Mac.
|
||||
|
||||
- Linking a module compiled with a different setting for Py_TRACE_REFS now
|
||||
generates a linker error rather than a core dump.
|
||||
|
||||
- The cgi module has a new convenience function print_exception(), which
|
||||
formats a python exception using HTML. It also fixes a bug in the
|
||||
compatibility code and adds a dubious feature which makes it possible to
|
||||
have two query strings, one in the URL and one in the POST data.
|
||||
|
||||
- A subtle change in the unpickling of class instances makes it possible
|
||||
to unpickle in restricted execution mode, where the __dict__ attribute is
|
||||
not available (but setattr() is).
|
||||
|
||||
- Documentation for os.path.splitext() (== posixpath.splitext()) has been
|
||||
cleared up. It splits at the *last* dot.
|
||||
|
||||
- posixfile locking is now also correctly supported on AIX.
|
||||
|
||||
- The tempfile module once again honors an initial setting of tmpdir. It
|
||||
now works on Windows, too.
|
||||
|
||||
- The traceback module has some new functions to extract, format and print
|
||||
the active stack.
|
||||
|
||||
- Some translation functions in the urllib module have been made a little
|
||||
less sluggish.
|
||||
|
||||
- The addtag_* methods for Canvas widgets in Tkinter as well as in the
|
||||
separate Canvas class have been fixed so they actually do something
|
||||
meaningful.
|
||||
|
||||
- A tiny _test() function has been added to Tkinter.py.
|
||||
|
||||
- A generic Makefile for dynamically loaded modules is provided in the Misc
|
||||
subdirectory (Misc/gMakefile).
|
||||
|
||||
- A new version of python-mode.el for Emacs is provided. Ask Barry Warsaw
|
||||
for a list of changes. The separate file pyimenu.el is no longer needed,
|
||||
imenu support is folded into python-mode.el.
|
||||
|
||||
- The configure script can finally correctly find the readline library in a
|
||||
non-standard location. The LDFLAGS variable is passed on the the Makefiles
|
||||
from the configure script.
|
||||
|
||||
- Shared libraries are now installed as programs (i.e. with executable
|
||||
permission). This is required on HP-UX and won't hurt on other systems.
|
||||
|
||||
- The objc.c module is no longer part of the distribution. Objective-C
|
||||
support may become available as contributed software on the ftp site.
|
||||
|
||||
- The sybase module is no longer part of the distribution. May John
|
||||
Redford rot in hell. A much improved sybase module is available as
|
||||
contributed software from the ftp site.
|
||||
|
||||
- _tkinter is now compatible with Tcl 7.5 / Tk 4.1 patch1 on Windows and
|
||||
Mac (don't use unpatched Tcl/Tk!). The default line in the Setup.in file
|
||||
now links with Tcl 7.5 / Tk 4.1 rather than 7.4/4.0.
|
||||
|
||||
- In Setup, you can now write "*shared*" instead of "*noconfig*", and you
|
||||
can use *.so and *.sl as shared libraries.
|
||||
|
||||
- Some more fidgeting for AIX shared libraries.
|
||||
|
||||
- The mpz module is now compatible with GMP 2.x. (Not tested by me.)
|
||||
|
||||
- A warning is written to sys.stderr when a __del__ method raises an
|
||||
exception (formerly, such exceptions were completely ignored).
|
||||
|
||||
- The configure script now defines HAVE_OLD_CPP if the C preprocessor is
|
||||
incapable of ANSI style token concatenation and stringification.
|
||||
|
||||
- All source files (except a few platform specific modules) are once again
|
||||
compatible with K&R C compilers as well as ANSI compilers. In particular,
|
||||
ANSI-isms have been removed or made conditional in complexobject.c,
|
||||
getargs.c and operator.c.
|
||||
|
||||
- The abstract object API has three new functions, PyObject_DelItem,
|
||||
PySequence_DelItem, and PySequence_DelSlice.
|
||||
|
||||
- The operator module has new functions delitem and delslice, and the
|
||||
functions "or" and "and" are renamed to "or_" and "and_" (since "or" and
|
||||
"and" are reserved words). ("__or__" and "__and__" are unchanged.)
|
||||
|
||||
- The environment module is no longer supported; putenv() is now a function
|
||||
in posixmodule (also under NT).
|
||||
|
||||
- Error in filter(<function>, "") has been fixed.
|
||||
|
||||
- Unrecognized keyword arguments raise TypeError, not KeyError.
|
||||
|
||||
- Better portability, fewer bugs and memory leaks, fewer compiler warnings,
|
||||
some more documentation.
|
||||
|
||||
- Bug in float power boundary case (0.0 to the negative integer power)
|
||||
fixed.
|
||||
|
||||
- The test of negative number to the float power has been moved from the
|
||||
built-in pow() functin to floatobject.c (so complex numbers can yield the
|
||||
correct result).
|
||||
|
||||
- The bug introduced in beta2 where shared libraries loaded (using
|
||||
dlopen()) from the current directory would fail, has been fixed.
|
||||
|
||||
- Modules imported as shared libraries now also have a __file__ attribute,
|
||||
giving the filename from which they were loaded. The only modules without
|
||||
a __file__ attribute now are built-in modules.
|
||||
|
||||
- On the Mac, dynamically loaded modules can end in either ".slb" or
|
||||
".<platform>.slb" where <platform> is either "CFM68K" or "ppc". The ".slb"
|
||||
extension should only be used for "fat" binaries.
|
||||
|
||||
- C API addition: marshal.c now supports
|
||||
PyMarshal_WriteObjectToString(object).
|
||||
|
||||
- C API addition: getargs.c now supports
|
||||
PyArg_ParseTupleAndKeywords(args, kwdict, format, kwnames, ...)
|
||||
to parse keyword arguments.
|
||||
|
||||
- The PC versioning scheme (sys.winver) has changed once again. the
|
||||
version number is now "<digit>.<digit>.<digit>.<apiversion>", where the
|
||||
first three <digit>s are the Python version (e.g. "1.4.0" for Python 1.4,
|
||||
"1.4.1" for Python 1.4.1 -- the beta level is not included) and
|
||||
<apiversion> is the four-digit PYTHON_API_VERSION (currently 1005).
|
||||
|
||||
- h2py.py accepts whitespace before the # in CPP directives
|
||||
|
||||
- On Solaris 2.5, it should now be possible to use either Posix threads or
|
||||
Solaris threads (XXX: how do you select which is used???). (Note: the
|
||||
Python pthreads interface doesn't fully support semaphores yet -- anyone
|
||||
care to fix this?)
|
||||
|
||||
- Thread support should now work on AIX, using either DCE threads or
|
||||
pthreads.
|
||||
|
||||
- New file Demo/sockets/unicast.py
|
||||
|
||||
- Working Mac port, with CFM68K support, with Tk 4.1 support (though not
|
||||
both) (XXX)
|
||||
|
||||
- New project setup for PC port, now compatible with PythonWin, with
|
||||
_tkinter and NumPy support (XXX)
|
||||
|
||||
- New module site.py (XXX)
|
||||
|
||||
- New module xdrlib.py and optional support module _xdrmodule.c (XXX)
|
||||
|
||||
- parser module adapted to new grammar, complete w/ Doc & Demo (XXX)
|
||||
|
||||
- Name mangling to support class-private variables: __spam is translated to
|
||||
_ClassName__spam (XXX)
|
||||
|
||||
- regen script fixed (XXX)
|
||||
|
||||
- new machdep subdirectories Lib/{aix3,aix4,next3_3,freebsd2,linux2} (XXX)
|
||||
|
||||
- testall now also tests math module (XXX)
|
||||
|
||||
- string.atoi c.s. now raise an exception for an empty input string.
|
||||
|
||||
- At last, it is no longer necessary to define HAVE_CONFIG_H in order to
|
||||
have config.h included at various places.
|
||||
|
||||
- Unrecognized keyword arguments now raise TypeError rather than KeyError.
|
||||
|
||||
- The makesetup script recognizes files with extension .so or .sl as
|
||||
(shared) libraries.
|
||||
|
||||
- 'access' is no longer a reserved word, and all code related to its
|
||||
implementation is gone (or at least #ifdef'ed out). This should make
|
||||
Python a little speedier too!
|
||||
|
||||
- Performance enhancements suggested by Sjoerd Mullender. This includes
|
||||
the introduction of two new optional function pointers in type object,
|
||||
getattro and setattro, which are like getattr and setattr but take a
|
||||
string object instead of a C string pointer.
|
||||
|
||||
- New operations in string module: lstrip(s) and rstrip(s) strip whitespace
|
||||
only on the left or only on the right, A new optional third argument to
|
||||
split() specifies the maximum number of separators honored (so
|
||||
splitfields(s, sep, n) returns a list of at most n+1 elements). (Since
|
||||
1.3, splitfields(s, None) is totally equivalent to split(s).)
|
||||
string.capwords() has an optional second argument specifying the
|
||||
separator (which is passed to split()).
|
||||
|
||||
- regsub.split() has the same addition as string.split(). regsub.splitx(s,
|
||||
sep, maxsep) implements the functionality that was regsub.split(s, 1) in
|
||||
1.4beta2 (return a list containing the delimiters as well as the words).
|
||||
|
||||
- Final touch for AIX loading, rewritten Misc/AIX-NOTES.
|
||||
|
||||
- In Modules/_tkinter.c, when using Tk 4.1 or higher, use className
|
||||
argument to _tkinter.create() to set Tcl's argv0 variable, so X
|
||||
resources use the right resource class again.
|
||||
|
||||
- Add #undef fabs to Modules/mathmodule.c for macintosh.
|
||||
|
||||
- Added some macro renames for AIX in Modules/operator.c.
|
||||
|
||||
- Removed spurious 'E' from Doc/liberrno.tex.
|
||||
|
||||
- Got rid of some cruft in Misc/ (dlMakefile, pyimenu.el); added new
|
||||
Misc/gMakefile and new version of Misc/python-mode.el.
|
||||
|
||||
- Fixed typo in Lib/ntpath.py (islink has "return false" which gives a
|
||||
NameError).
|
||||
|
||||
- Added missing "from types import *" to Lib/tkinter/Canvas.py.
|
||||
|
||||
- Added hint about using default args for __init__ to pickle docs.
|
||||
|
||||
- Corrected typo in Inclide/abstract.h: PySequence_Lenth ->
|
||||
PySequence_Length.
|
||||
|
||||
- Some improvements to Doc/texi2html.py.
|
||||
|
||||
- In Python/import.c, Cast unsigned char * in struct _frozen to char *
|
||||
in calls to rds_object().
|
||||
|
||||
- In doc/ref4.tex, added note about scope of lambda bodies.

------------------------------------
|

What's new in 1.4beta1 (since 1.3)?
|
||||
-----------------------------------
|
||||
|
||||
- Added sys.platform and sys.exec_platform for Bill Janssen.
|
||||
|
||||
XXX more...
|
||||
- Installation has been completely overhauled. "make install" now installs
|
||||
everything, not just the python binary. Installation uses the install-sh
|
||||
script (borrowed from X11) to install each file.
|
||||
|
||||
- New functions in the posix module: mkfifo, plock, remove (== unlink),
|
||||
and ftruncate. More functions are also available under NT.
|
||||
|
||||
- New function in the fcntl module: flock.
|
||||
|
||||
- Shared library support for FreeBSD.
|
||||
|
||||
- The --with-readline option can now be used without a DIRECTORY argument,
|
||||
for systems where libreadline.* is in one of the standard places. It is
|
||||
also possible for it to be a shared library.
|
||||
|
||||
- The extension tkinter has been renamed to _tkinter, to avoid confusion
|
||||
with Tkinter.py oncase insensitive file systems. It now supports Tk 4.1 as
|
||||
well as 4.0.
|
||||
|
||||
- Author's change of address from CWI in Amsterdam, The Netherlands, to
|
||||
CNRI in Reston, VA, USA.
|
||||
|
||||
- The math.hypot() function is now always available (if it isn't found in
|
||||
the C math library, Python provides its own implementation).
|
||||
|
||||
- The latex documentation is now compatible with latex2e, thanks to David
|
||||
Ascher.
|
||||
|
||||
- The expression x**y is now equivalent to pow(x, y).
|
||||
|
||||
- The indexing expression x[a, b, c] is now equivalent to x[(a, b, c)].
|
||||
|
||||
- Complex numbers are now supported. Imaginary constants are written with
|
||||
a 'j' or 'J' prefix, general complex numbers can be formed by adding a real
|
||||
part to an imaginary part, like 3+4j. Complex numbers are always stored in
|
||||
floating point form, so this is equivalent to 3.0+4.0j. It is also
|
||||
possible to create complex numbers with the new built-in function
|
||||
complex(re, [im]). For the footprint-conscious, complex number support can
|
||||
be disabled by defining the symbol WITHOUT_COMPLEX.
|
||||
|
||||
- New built-in function list() is the long-awaited counterpart of tuple().
|
||||
|
||||
- There's a new "cmath" module which provides the same functions as the
|
||||
"math" library but with complex arguments and results. (There are very
|
||||
good reasons why math.sqrt(-1) still raises an exception -- you have to use
|
||||
cmath.sqrt(-1) to get 1j for an answer.)
|
||||
|
||||
- The Python.h header file (which is really the same as allobjects.h except
|
||||
it disables support for old style names) now includes several more files,
|
||||
so you have to have fewer #include statements in the average extension.
|
||||
|
||||
- The NDEBUG symbol is no longer used. Code that used to be dependent on
|
||||
the presence of NDEBUG is now present on the absence of DEBUG. TRACE_REFS
|
||||
and REF_DEBUG have been renamed to Py_TRACE_REFS and Py_REF_DEBUG,
|
||||
respectively. At long last, the source actually compiles and links without
|
||||
errors when this symbol is defined.
|
||||
|
||||
- Several symbols that didn't follow the new naming scheme have been
|
||||
renamed (usually by adding to rename2.h) to use a Py or _Py prefix. There
|
||||
are no external symbols left without a Py or _Py prefix, not even those
|
||||
defined by sources that were incorporated from elsewhere (regexpr.c,
|
||||
md5c.c). (Macros are a different story...)
|
||||
|
||||
- There are now typedefs for the structures defined in config.c and
|
||||
frozen.c.
|
||||
|
||||
- New PYTHON_API_VERSION value and .pyc file magic number.
|
||||
|
||||
- New module Bastion. (XXX)
|
||||
|
||||
- Improved performance of StringIO module.
|
||||
|
||||
- UserList module now supports + and * operators.
|
||||
|
||||
- The binhex and binascii modules now actually work.
|
||||
|
||||
- The cgi module has been almost totally rewritten and documented.
|
||||
It now supports file upload and a new data type to handle forms more
|
||||
flexibly.
|
||||
|
||||
- The formatter module (for use with htmllib) has been overhauled (again).
|
||||
|
||||
- The ftplib module now supports passive mode and has doc strings.
|
||||
|
||||
- In (ideally) all places where binary files are read or written, the file
|
||||
is now correctly opened in binary mode ('rb' or 'wb') so the code will work
|
||||
on Mac or PC.
|
||||
|
||||
- Dummy versions of os.path.expandvars() and expanduser() are now provided
|
||||
on non-Unix platforms.
|
||||
|
||||
- Module urllib now has two new functions url2pathname and pathname2url
|
||||
which turn local filenames into "file:..." URLs using the same rules as
|
||||
Netscape (why be different). it also supports urlretrieve() with a
|
||||
pathname parameter, and honors the proxy environment variables (http_proxy
|
||||
etc.). The URL parsing has been improved somewhat, too.
|
||||
|
||||
- Micro improvements to urlparse. Added urlparse.urldefrag() which
|
||||
removes a trailing ``#fragment'' if any.
|
||||
|
||||
- The mailbox module now supports MH style message delimiters as well.
|
||||
|
||||
- The mhlib module contains some new functionality: setcontext() to set the
|
||||
current folder and parsesequence() to parse a sequence as commonly passed
|
||||
to MH commands (e.g. 1-10 or last:5).
|
||||
|
||||
- New module mimify for conversion to and from MIME format of email
|
||||
messages.
|
||||
|
||||
- Module ni now automatically installs itself when first imported -- this
|
||||
is against the normal rule that modules should define classes and functions
|
||||
but not invoke them, but appears more useful in the case that two
|
||||
different, independent modules want to use ni's features.
|
||||
|
||||
- Some small performance enhancements in module pickle.
|
||||
|
||||
- Small interface change to the profile.run*() family of functions -- more
|
||||
sensible handling of return values.
|
||||
|
||||
- The officially registered Mac creator for Python files is 'Pyth'. This
|
||||
replaces 'PYTH' which was used before but never registered.
|
||||
|
||||
- Added regsub.capwords(). (XXX)
|
||||
|
||||
- Added string.capwords(), string.capitalize() and string.translate().
|
||||
(XXX)
|
||||
|
||||
- Fixed an interface bug in the rexec module: it was impossible to pass a
|
||||
hooks instance to the RExec class. rexec now also supports the dynamic
|
||||
loading of modules from shared libraries. Some other interfaces have been
|
||||
added too.
|
||||
|
||||
- Module rfc822 now caches the headers in a dictionary for more efficient
|
||||
lookup.
|
||||
|
||||
- The sgmllib module now understands a limited number of SGML "shorthands"
|
||||
like <A/.../ for <A>...</A>. (It's not clear that this was a good idea...)
|
||||
|
||||
- The tempfile module actually tries a number of different places to find a
|
||||
usable temporary directory. (This was prompted by certain Linux
|
||||
installations that appear to be missing a /usr/tmp directory.) [A bug in
|
||||
the implementation that would ignore a pre-existing tmpdir global has been
|
||||
fixed in beta3.]
|
||||
|
||||
- Much improved and enhanved FileDialog module for Tkinter.
|
||||
|
||||
- Many small changes to Tkinter, to bring it more in line with Tk 4.0 (as
|
||||
well as Tk 4.1).
|
||||
|
||||
- New socket interfaces include ntohs(), ntohl(), htons(), htonl(), and
|
||||
s.dup(). Sockets now work correctly on Windows. On Windows, the built-in
|
||||
extension is called _socket and a wrapper module win/socket.py provides
|
||||
"makefile()" and "dup()" functionality. On Windows, the select module
|
||||
