Issue #1580: New free format floating point representation based on "Floating-Point Printer Sample Code", by Robert G. Burger. For example repr(11./5) now returns '2.2' instead of '2.2000000000000002'.
Thanks to noam for the patch! I had to modify doubledigits.c slightly to support X64 and IA64 machines on Windows. I also added the new file to the three project files.
on 32-bit systems on 64-bit systems, and vice versa. As a consequence
of the change, Random pickles created by Python 2.6 cannot be loaded
in Python 2.5.
Added PyFloat_GetMax(), PyFloat_GetMin() and PyFloat_GetInfo() to the float API.
Added a dictionary sys.float_info with information about the internal floating point type to the sys module.
(in deallocation of running threads, for example), so the PyGILState_Release()
function must still be functional.
On the other hand, _PyGILState_Fini() only frees memory, and can be called later.
Backport candidate, but only after some experts comment on it.
number: now it does not store the mantissa as a tuple
of numbers, but as a string.
This avoids a lot of conversions, and achieves a
speedup of 40%. The API remains intact.
Thanks Mark Dickinson.
newlines; it doesn't. To rectify this the string returned replaces all
instances of os.linesep with '\n' to fake universal newline support.
Backport candidate.
as usual with slicing (both with str and unicode strings). This
fixes issue 1259.
For str only the stringobject.c file was modified. But for unicode,
I needed to repeat in the four functions a lot of code, so created
a new function that does part of the job for them (and placed it in
find.h, following a suggestion of Barry).
Also added tests for this behaviour.
(suprisingly, this simplifies the signature, improves clarity, and is comparably fast).
Update the docs to reflect a previous change to the function name.
Add an example to the docs showing how to override the default __repr__ method.
Correction for issue1265 (pdb bug with "with" statement).
When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set. This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.
It is necessary to save/restore the exception around the call to the trace
function.
This happens a lot with py3k: isinstance() of an ABCMeta instance runs
def __instancecheck__(cls, instance):
"""Override for isinstance(instance, cls)."""
return any(cls.__subclasscheck__(c)
for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.
Backport candidate, even if the case is less frequent in 2.5.
coefficient numbers, floats in the sign, and other details that
generated directly the wrong number in the best case, or triggered
misfunctionality in the alorithms.
Test cases added for these issues. Thanks Mark Dickinson.
it closes itself. When the stream is read in several calls to read(n),
it should behave in the same way if HTTPConnection knows where the end
of the stream is (through self.length). Added a test case for this
behaviour.
This should make the tests more robust at the expense of allowing
tests to be sloppier by not requiring them to cleanup after themselves.
(It will legitamitely help when running two test suites simultaneously
or if another process is already using one of the predefined ports.)
Also simplifies (slightLy) the exception handling elsewhere.
Let the field spec be either a string or a non-string sequence (suggested by Martin Blais with use cases).
Improve the error message in the case of a SyntaxError (caused by a duplicate field name).
Add maxlen support to deque() and fixup docs.
Partially fix __reduce__(). The None as a third arg was no longer supported.
Still needs work on __reduce__() to handle recursive inputs.
with Cawlishaw by mail, and he basically confirmed that to these is_*
operations, there's no need to return Decimal(0) and Decimal(1) if
the language supports the False and True booleans.
Also added a few tests for the these functions in extra.decTest, since
they are mostly untested (apart from the doctests).
Thanks Mark Dickinson
predictable to being completely predictable. The value of hash(n)
is unchanged for any n that's small enough to be representable as an
int, and also unchanged for the vast majority of long integers n of
reasonable size.
Allows optional commas in the field-name spec (help when named tuples are used in conjuction with sql queries).
Adds the __fields__ attribute for introspection and to support conversion to dictionary form.
Adds a __replace__() method similar to str.replace() but using a named field as a target.
Clean-up spelling and presentation in doc-strings.
adding the 'makefile' method to ssl.SSLSocket, and importing the
requisite fakefile class from socket.py, and making the appropriate
changes to it to make it use the SSL connection.
Added sample HTTPS server to test_ssl.py, and test that uses it.
Change SSL tests to use https://svn.python.org/, instead of
www.sf.net and pop.gmail.com.
Added utility function to ssl module, get_server_certificate,
to wrap up the several things to be done to pull a certificate
from a remote server.
fully updated to the latests Decimal Specification (v1.66) and the
latests test cases (v2.56).
Thanks to Mark Dickinson for all his help during this process.
Backport abc.py and isinstance/issubclass overloading to 2.6.
I had to backport test_typechecks.py myself, and make one small change
to abc.py to avoid duplicate work when x.__class__ and type(x) are the
same.
Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).
Could be backported to 2.5; no need to port to 3.0.
* Much expanded test suite:
All protocols tested against all other protocols.
All protocols tested with all certificate options.
Tests for bad key and bad cert.
Test of STARTTLS functionality.
Test of RAND_* functions.
* Fixes for threading/malloc bug.
* Issue 1065 fixed:
sslsocket class renamed to SSLSocket.
sslerror class renamed to SSLError.
Function "wrap_socket" now used to wrap an existing socket.
* Issue 1583946 finally fixed:
Support for subjectAltName added.
Subject name now returned as proper DN list of RDNs.
* SSLError exported from socket as "sslerror".
* RAND_* functions properly exported from ssl.py.
* Documentation improved:
Example of how to create a self-signed certificate.
Better indexing.

I chose IOError rather than EnvironmentError as the base class since
socket objects are often used as transparent duck typed file objects
in code already prepared to deal with IOError exceptions.
also a minor fix:
urllib2 - fix a couple places where IOError was raised rather than URLError.
for better or worse, URLError already inherits from IOError so
this won't break any existing code.
test_urllib2net - replace bad ftp urls.
ever going back out to Python code in PyObject_Call(). Required introducing a
static RuntimeError instance so that normalizing an exception there is no
reliance on a recursive call that would put the exception system over the
recursion check itself.
1) Improve the documentation of the SSL module, with a fuller
explanation of certificate usage, another reference, proper
formatting of this and that.
2) Fix Windows bug in ssl.py, and general bug in sslsocket.close().
Remove some unused code from ssl.py. Allow accept() to be called on
sslsocket sockets.
3) Use try-except-else in import of ssl in socket.py. Deprecate use of
socket.ssl().
4) Remove use of socket.ssl() in every library module, except for
test_socket_ssl.py and test_ssl.py.
- Specialcase extended slices that amount to a shallow copy the same way as
is done for simple slices, in the tuple, string and unicode case.
- Specialcase step-1 extended slices to optimize the common case for all
involved types.
- For lists, allow extended slice assignment of differing lengths as long
as the step is 1. (Previously, 'l[:2:1] = []' failed even though
'l[:2] = []' and 'l[:2:None] = []' do not.)
- Implement extended slicing for buffer, array, structseq, mmap and
UserString.UserString.
- Implement slice-object support (but not non-step-1 slice assignment) for
UserString.MutableString.
- Add tests for all new functionality.

Here's a patch that does that.

exceptions raised in the test server thread, since SimpleXMLRPCServer
does not gracefully handle them. Changed number of requests handled
by tests server thread to one (was 2) because no tests require more
than one request. [GSoC - Alan McIntyre]
1) Fixes the bug that two class names are initial-lower-case.
2) Replaces the poll waiting for the server to become ready with
a threading.Event signal.
object's co_consts tuple; add a test to show that the previous behavior (where
these two constants were "collapsed" into one) causes serious malfunctioning.
and tests for NOOP, RSET, and VRFY. Corrected typo in a comment for
testNonnumericPort. Added a check for constructing SMTP objects when
non-numeric ports are included in the host name. Derived a server from
SMTPServer to test various ESMTP/SMTP capabilities. Check that a
second HELO to DebuggingServer returns an error. [GSoC - Alan McIntyre]
that allows sending back exception/stack trace information about
internal server errors (this flag defaults to False to avoid sending
such information unless explicitly enabled). Added tests to verify
behavior of this new feature (these tests are skipped on win32 because
of problems with WSAEWOULDBLOCK). Renamed HTTPTestCase to
SimpleServerTestCase. [GSoC - Alan McIntyre]
against a SimpleXMLRPCServer in a separate thread. Because of
problems with WSAEWOULDBLOCK (error 10035) being raised by the server
on Windows, these new tests are skipped on win32. [GSoC - Alan McIntyre]
test.test_support.catch_warning is more full-featured and provides the same
functionality.
Since guard_warnings_filter was added in 2.6 there is no
backwards-compatibility issues.
DebuggingServerTests, construct SMTP objects with a localhost argument
to avoid abysmally long FQDN lookups (not relevant to items under
test) on some machines that would cause the test to fail. Moved server
setup code in the server function inside the try block to avoid the
possibility of setup failure hanging the test. Minor edits to conform
to PEP 8. [GSoC - Alan McIntyre]
overrides asyncore.dispatcher.handle_expt to do nothing, since
select.poll gives a POLLHUP error at the completion of these tests.
Added timeout & count arguments to several asyncore.loop calls to
avoid the possibility of a test hanging up a build. [GSoC - Alan
McIntyre]
find_prefix_at_end function. Check behavior of a string given as a
producer. Added tests for behavior of asynchat.async_chat when given
int, long, and None terminator arguments. Added usepoll attribute to
TestAsynchat to allow running the asynchat tests with poll support
chosen whether it's available or not (improves coverage of asyncore
code). [GSoC - Alan McIntyre]
so that the event gets set if a failure occurs during server setup
(otherwise the test will block forever). Changed to let the OS assign
the server port number, and client side of test waits for port number
assignment before proceeding. The test data in DispatcherWithSendTests
is also sent in multiple send() calls instead of one to make sure this
works properly. [GSoC - Alan McIntyre]
smtpd.DebuggingServer. Change to use global host & port number
variables. Modified the 'server' to take a string to send back in
order to vary test server responses. Added a test for the reaction of
smtplib.SMTP to a non-200 HELO response. [GSoC - Alan McIntyre]
to server & client, and by adding asyncore.close_all calls in
tearDown. Also choose correct expected logging results based on the
value of __debug__ [Alan McIntyre - GSoC]
The Maildir specification doesn't seem to say anything about this
situation, and it can happen if you're keeping a Maildir mailbox in
Subversion (.svn directories) or some similar system. The patch just
ignores directories in the cur/, new/, tmp/ folders.
a large width is passed on 32-bit platforms. Found by Google.
It would be good for people to review this especially carefully and verify
I don't have an off by one error and there is no other way to cause overflow.
with tests in test_urllib2net.py (must have network resource
enabled to execute them). Also modified test_urllib2.py because
testing mock classes must take it into acount. Docs are also
updated.
specify an error handling scheme for character conversion. Additional
scheme "utf-8" in read mode. Unicode input filenames are now
supported by design. The values of the pax_headers dictionary are now
limited to unicode objects.
Fixed: The prefix field is no longer used in PAX_FORMAT (in
conformance with POSIX).
Fixed: In read mode use a possible pax header size field.
Fixed: Strip trailing slashes from pax header name values.
Fixed: Give values in user-specified pax_headers precedence when
writing.
Added unicode tests. Added pax/regtype4 member to testtar.tar all
possible number fields in a pax header.
Added two chapters to the documentation about the different formats
tarfile.py supports and how unicode issues are handled.
Python 2.5.
Also remove gopher support from urllib/urllib2. As both imported gopherlib the
usage of the support would have raised a DeprecationWarning.
are zero. This should help reduce the false positives.
The message about references leaking is maintained to provide as much
info as possible rather than simply suppressing the message at the source.
If the call to requires() doesn't precede the filesystem check, we get the following situation:
1. ./python Lib/test/regrtest.py test_foo # test needs urlfetch, not enabled, so skipped
2. ./python Lib/test/regrtest.py -u urlfetch test_foo # test runs
3. ./python Lib/test/regrtest.py test_foo # test runs (!)
By moving the call to requires() *before* the filesystem check, the fact that fetched files are cached on the local disk becomes an implementation detail, rather than a semantics-changing point of note.
