PEP: 200
|
||
Title: Python 2.0 Release Schedule
|
||
Version: $Revision$
|
||
Owner: Jeremy Hylton <jeremy@beopen.com>
|
||
Python-Version: 2.0
|
||
Status: Incomplete
|
||
|
||
|
||
Introduction
|
||
|
||
This PEP describes the Python 2.0 release schedule, tracking the
|
||
status and ownership of the major new features, summarizes
|
||
discussions held in mailing list forums, and provides URLs for
|
||
further information, patches, and other outstanding issues. The
|
||
CVS revision history of this file contains the definitive
|
||
historical record.
|
||
|
||
|
||
Tentative Release Schedule
|
||
|
||
14-Aug-2000: All 2.0 PEPs finished / feature freeze
|
||
28-Aug-2000: 2.0 beta 1
|
||
29-Sep-2000: 2.0 final
|
||
|

|
||
Guidelines for submitting patches and making changes
|
||
|
||
Use good sense when committing changes. You should know what we
|
||
mean by good sense or we wouldn't have given you commit privileges
|
||
<0.5 wink>. Some specific examples of good sense include:
|
||
|
||
- Do whatever the dictator tells you.
|
||
|
||
- Discuss any controversial changes on python-dev first. If you
|
||
get a lot of +1 votes and no -1 votes, make the change. If you
|
||
get a some -1 votes, think twice; consider asking Guido what he
|
||
thinks.
|
||
|
||
- If the change is to code you contributed, it probably makes
|
||
sense for you to fix it.
|
||
|
||
- If the change affects code someone else wrote, it probably makes
|
||
sense to ask him or her first.
|
||
|
||
- You can use the SF Patch Manager to submit a patch and assign it
|
||
to someone for review.
|
||
|
||
Any significant new feature must be described in a PEP and
|
||
approved before it is checked in.
|
||
|
||
Any significant code addition, such as a new module or large
|
||
patch, must include test cases for the regression test and
|
||
documentation. A patch should not be checked in until the tests
|
||
and documentation are ready.
|
||
|
||
If you fix a bug, you should write a test case that would have
|
||
caught the bug.
|
||
|
||
If you commit a patch from the SF Patch Manager or fix a bug from
|
||
the Jitterbug database, be sure to reference the patch/bug number
|
||
in the CVS log message. Also be sure to change the status in the
|
||
patch manager or bug database (if you have access to the bug
|
||
database).
|
||
|
||
It is not acceptable for any checked in code to cause the
|
||
regression test to fail. If a checkin causes a failure, it must
|
||
be fixed within 24 hours or it will be backed out.
|
||
|
||
All contributed C code must be ANSI C. If possible check it with
|
||
two different compilers, e.g. gcc and MSVC.
|
||
|
||
All contributed Python code must follow Guido's Python style
|
||
guide. http://www.python.org/doc/essays/styleguide.html
|
||
|
||
It is understood that any code contributed will be released under
|
||
an Open Source license. Do not contribute code if it can't be
|
||
released this way.
|
||
|
||
|
||
Failing test cases need to get fixed
|
||
|
||
We need to resolve errors in the regression test suite quickly.
|
||
Changes should not be committed to the CVS tree unless the
|
||
regression test runs cleanly with the changes applied. If it
|
||
fails, there may be bugs lurking in the code. (There may be bugs
|
||
anyway, but that's another matter.) If the test cases are known
|
||
to fail, they serve no useful purpose.
|
||
|
||
[what are the "R" and "B" columns supposed to mean? - tim]
|
||
|
||
test case platform R B date reported
|
||
--------- -------- - - -------------
|
||
test_winreg2 Win32 X X 26-Jul-2000
|
||
[still fails 15-Aug-2000 for me, on Win98 - tim
|
||
test test_winreg2 failed -- Writing: 'Test Failed: testHives',
|
||
expected: 'HKEY_PERFORMANCE_DATA\012'
|
||
]
|
||
|
||
test_popen2 Win32 X X 26-Jul-2000
|
||
[still fails 15-Aug-2000 for me, on Win98 - tim
|
||
test test_popen2 crashed -- exceptions.AssertionError :
|
||
The problem is that the test uses "cat", but there is
|
||
no such thing under Windows (unless you install it).
|
||
So it's the test that's broken here, not (necessarily)
|
||
the code.
|
||
]
|
||
|
||
test_fork1 Linux X 26-Jul-2000 just SMP?
|
||
[no clue; there are probably two bugs here]
|
||
|
||
|
||
Previously failing test cases
|
||
|
||
If you find a test bouncing between this section and the previous one,
|
||
the code it's testing is in trouble!
|
||
|
||
test case platform R B date reported
|
||
--------- -------- - - -------------
|
||
test_winreg Win32 X X 26-Jul-2000
|
||
[works 15-Aug-2000 for me, on Win98 - tim]
|
||
|
||
test_mmap Win32 X X 26-Jul-2000
|
||
[believe that was fixed by Mark H.]
|
||
[works 15-Aug-2000 for me, on Win98 - tim]
|
||
|
||
|
||
Open items -- should be done/fixed
|
||
|
||
Decoding errors when comparing strings. There is a dictionary bug
|
||
that prevents objects from being accessible when an exception is
|
||
raised during hashing or comparison.
|
||
|
||
|
||
Accepted and completed
|
||
|
||
* Lockstep iteration ("zip" function) - Barry Warsaw
|
||
|
||
* SRE - Fredrik Lundh
|
||
[at least I *think* it's done, as of 15-Aug-2000 - tim]
|
||
|
||
* Fix xrange printing behavior - Fred Drake
|
||
[although I'm not sure what this one was talking about - tim]
|
||
|
||
|
||
Accepted and in progress
|
||
|
||
* SyntaxError enhancements - Fredrik Lundh
|
||
http://www.python.org/pipermail/python-dev/2000-July/012981.html
|
||
|
||
* interface to poll system call - Andrew Kuchling
|
||
An OO interface to the poll system call will be added to the
|
||
select module.
|
||
|
||
* Compression of Unicode database - Fredrik Lundh
|
||
http://hem.passagen.se/eff/bot.htm#456806
|
||
|
||
* PyErr_SafeFormat / snprintf - owner???
|
||
Use snprintf to avoid buffer overflows. Need configure hackery
|
||
to discovery if it is available on the current platform and a
|
||
default implementation if it is not.
|
||
http://www.python.org/pipermail/python-dev/2000-April/010051.html
|
||
|
||
* Support for opcode arguments > 2**16 - Charles Waldman
|
||
Source files longer than 32K and sequences with more than 32K
|
||
elements both fail because opcode arguments are limited to
|
||
16-bit values.
|
||
|
||
* Range literals - Thomas Wouters
|
||
Make range(1, 10, 2) == [1:10:2]
|
||
|
||
* List comprehensions - Skip Montanaro (Tim Peters for PEP)
|
||
Need a coherent proposal. Lots of confusing discussion going
|
||
on.
|
||
[note: it's not confusing to Guido <wink> - tim]
|
||
|
||
|
||
Open: proposed but not accepted or declined
|
||
|
||
* Tim O'Malley's cookie module -- but need different license
|
||
|
||
* test harness for C code - Trent Mick
|
||
|
||
* Eliminated SET_LINENO opcode - Vladimir Marangozov
|
||
Small optimization achieved by using the code object's lnotab
|
||
instead of the SET_LINENO instruction. Uses code rewriting
|
||
technique (that Guido's frowns on) to support debugger, which
|
||
uses SET_LINENO.

Discussions on python-dev:
|
||
|

|
||
Subject: "Why do we need Traceback Objects?"
|
||
|
||
- http://www.python.org/pipermail/python-dev/1999-August/002252.html
|
||
|
||
* Augmented assignment - Thomas Wouters
|
||
Add += and family, plus Python and C hooks, and API functions.
|
||
|
||
* "import as" - Thomas Wouters
|
||
Extend the 'import' and 'from ... import' mechanism to enable
|
||
importing a symbol as another name.
|
||
|
||
* Extended slicing on lists - Michael Hudson
|
||
Make lists (and other builtin types) handle extended slices.
|
||
|
||
* Merge __getitem__ and __getslice__ - Thomas Wouters
|
||
Move __getslice__ functionality into __getitem__, using slice objects,
|
||
for normal slices as well as for extended ones. First step: use
|
||
getitem if there is no getslice.
