|

|
||||
|
||||
=====================================
|
||||
==> Release 1.3 (13 October 1995) <==
|
||||
=====================================
|
||||
|
||||
Major change
|
||||
============
|
||||
|
||||
Two words: Keyword Arguments. See the first section of Chapter 12 of
|
||||
the Tutorial.
|
||||
|
||||
(The rest of this file is textually the same as the remaining sections
|
||||
of that chapter.)
|
||||
|
||||
|
||||
Changes to the WWW and Internet tools
|
||||
=====================================
|
||||
|
||||
The "htmllib" module has been rewritten in an incompatible fashion.
|
||||
The new version is considerably more complete (HTML 2.0 except forms,
|
||||
but including all ISO-8859-1 entity definitions), and easy to use.
|
||||
Small changes to "sgmllib" have also been made, to better match the
|
||||
tokenization of HTML as recognized by other web tools.
|
||||
|
||||
A new module "formatter" has been added, for use with the new
|
||||
"htmllib" module.
|
||||
|
||||
The "urllib"and "httplib" modules have been changed somewhat to allow
|
||||
overriding unknown URL types and to support authentication. They now
|
||||
use "mimetools.Message" instead of "rfc822.Message" to parse headers.
|
||||
The "endrequest()" method has been removed from the HTTP class since
|
||||
it breaks the interaction with some servers.
|
||||
|
||||
The "rfc822.Message" class has been changed to allow a flag to be
|
||||
passed in that says that the file is unseekable.
|
||||
|
||||
The "ftplib" module has been fixed to be (hopefully) more robust on
|
||||
Linux.
|
||||
|
||||
Several new operations that are optionally supported by servers have
|
||||
been added to "nntplib": "xover", "xgtitle", "xpath" and "date".
|
||||
|
||||
Other Language Changes
|
||||
======================
|
||||
|
||||
The "raise" statement now takes an optional argument which specifies
|
||||
the traceback to be used when printing the exception's stack trace.
|
||||
This must be a traceback object, such as found in "sys.exc_traceback".
|
||||
When omitted or given as "None", the old behavior (to generate a stack
|
||||
trace entry for the current stack frame) is used.
|
||||
|
||||
The tokenizer is now more tolerant of alien whitespace. Control-L in
|
||||
the leading whitespace of a line resets the column number to zero,
|
||||
while Control-R just before the end of the line is ignored.
|
||||
|
||||
Changes to Built-in Operations
|
||||
==============================
|
||||
|
||||
For file objects, "f.read(0)" and "f.readline(0)" now return an empty
|
||||
string rather than reading an unlimited number of bytes. For the
|
||||
latter, omit the argument altogether or pass a negative value.
|
||||
|
||||
A new system variable, "sys.platform", has been added. It specifies
|
||||
the current platform, e.g. "sunos5" or "linux1".
|
||||
|
||||
The built-in functions "input()" and "raw_input()" now use the GNU
|
||||
readline library when it has been configured (formerly, only
|
||||
interactive input to the interpreter itself was read using GNU
|
||||
readline). The GNU readline library provides elaborate line editing
|
||||
and history. The Python debugger ("pdb") is the first beneficiary of
|
||||
this change.
|
||||
|
||||
Two new built-in functions, "globals()" and "locals()", provide access
|
||||
to dictionaries containming current global and local variables,
|
||||
respectively. (These augment rather than replace "vars()", which
|
||||
returns the current local variables when called without an argument,
|
||||
and a module's global variables when called with an argument of type
|
||||
module.)
|
||||
|
||||
The built-in function "compile()" now takes a third possible value for
|
||||
the kind of code to be compiled: specifying "'single'" generates code
|
||||
for a single interactive statement, which prints the output of
|
||||
expression statements that evaluate to something else than "None".
|
||||
|
||||
Library Changes
|
||||
===============
|
||||
|
||||
There are new module "ni" and "ihooks" that support importing modules
|
||||
with hierarchical names such as "A.B.C". This is enabled by writing
|
||||
"import ni; ni.ni()" at the very top of the main program. These
|
||||
modules are amply documented in the Python source.
|
||||
|
||||
The module "rexec" has been rewritten (incompatibly) to define a class
|
||||
and to use "ihooks".
|
||||
|
||||
The "string.split()" and "string.splitfields()" functions are now the
|
||||
same function (the presence or absence of the second argument
|
||||
determines which operation is invoked); similar for "string.join()"
|
||||
and "string.joinfields()".
|
||||
|
||||
The "Tkinter" module and its helper "Dialog" have been revamped to use
|
||||
keyword arguments. Tk 4.0 is now the standard. A new module
|
||||
"FileDialog" has been added which implements standard file selection
|
||||
dialogs.
|
||||
|
||||
The optional built-in modules "dbm" and "gdbm" are more coordinated
|
||||
--- their "open()" functions now take the same values for their "flag"
|
||||
argument, and the "flag" and "mode" argument have default values (to
|
||||
open the database for reading only, and to create the database with
|
||||
mode "0666" minuse the umask, respectively). The memory leaks have
|
||||
finally been fixed.
|
||||
|
||||
A new dbm-like module, "bsddb", has been added, which uses the BSD DB
|
||||
package's hash method.
|
||||
|
||||
A portable (though slow) dbm-clone, implemented in Python, has been
|
||||
added for systems where none of the above is provided. It is aptly
|
||||
dubbed "dumbdbm".
|
||||
|
||||
The module "anydbm" provides a unified interface to "bsddb", "gdbm",
|
||||
"dbm", and "dumbdbm", choosing the first one available.
|
||||
|
||||
A new extension module, "binascii", provides a variety of operations
|
||||
for conversion of text-encoded binary data.
|
||||
|
||||
There are three new or rewritten companion modules implemented in
|
||||
Python that can encode and decode the most common such formats: "uu"
|
||||
(uuencode), "base64" and "binhex".
|
||||
|
||||
A module to handle the MIME encoding quoted-printable has also been
|
||||
added: "quopri".
|
||||
|
||||
The parser module (which provides an interface to the Python parser's
|
||||
abstract syntax trees) has been rewritten (incompatibly) by Fred
|
||||
Drake. It now lets you change the parse tree and compile the result!
|
||||
|
||||
The \code{syslog} module has been upgraded and documented.
|
||||
|
||||
Other Changes
|
||||
=============
|
||||
|
||||
The dynamic module loader recognizes the fact that different filenames
|
||||
point to the same shared library and loads the library only once, so
|
||||
you can have a single shared library that defines multiple modules.
|
||||
(SunOS / SVR4 style shared libraries only.)
|
||||
|
||||
Jim Fulton's ``abstract object interface'' has been incorporated into
|
||||
the run-time API. For more detailes, read the files
|
||||
"Include/abstract.h" and "Objects/abstract.c".
|
||||
|
||||
The Macintosh version is much more robust now.
|
||||
|
||||
Numerous things I have forgotten or that are so obscure no-one will
|
||||
notice them anyway :-)

XXX This file still has to be updated!
|

|

Two words: Keyword Arguments. See the first section of Chapter 12 of

Some highlights:
|
||||
|
||||
(The rest of this file is textually the same as the remaining sections
|

|
||||
- "make install" overhaul to install everything and use a version number
|

|

- new builtin modules operator, errno
|

|

|

- x[a, b, c]
|

- x[a, ..., z]
|
||||
|
||||
A new module "formatter" has been added, for use with the new
