problems is in the bug report (one old, one recently introduced trying
to fix the old one). In short:
buffer data during socket._fileobject.read() and readlines() within a
cStringIO object instead of a [] of str()s returned from the recv()
call.
This prevents excessive memory use due to the size parameter being
passed to recv() being grossly larger than the actual size of the data
returned *and* prevents excessive cpu usage due to looping in python
calling recv() with a very tiny size value if min() is used as the
previous memory-use bug "fix" did.
It also documents what the socket._fileobject._rbufsize member is
actually used for.
This is a candidate for back porting to 2.5.
needed (better set available in Lib/test/test_robotparser.py). Clean up a
few PEP 8 nits (compound statements on a single line, whitespace around
operators).
* Avoid creating unused local variables where we can. Where we can't prefix
the unused variables with '_'.
* Avoid shadowing builtins where it won't change the external interface of a
function.
* Use None as default path arg to readmodule and readmodule_ex.
* The only exception we should catch when trying to import cStringIO is an
ImportError.
* Delete the function signatures embedded in the mk*temp docstrings.
* The tempdir global variable was initialized twice.
This is a modified version of a patch proposed by Humberto Diogenes
in the discussion of issue1883.
I will merge manually this change into the py3k branch: the tests must be adapted.
* Default to using /dev/tty for the password prompt and input before
falling back to sys.stdin and sys.stderr.
* Use sys.stderr instead of sys.stdout.
* print the 'password may be echoed' warning to stream used to display
the prompt rather than always sys.stderr.
* warn() with GetPassWarning when input may be echoed.
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.
Closes issue #1631171.
This might help fix some of the failures on Windows box(es). It doesn't hurt
either way and ensure the tests are a little more self contained (ie have
less assumptions).

Fix for http://bugs.python.org/issue2596
This extends fix_xrange to know about the (mostly) same special contexts as fix_dict (where a special context is something that is guaranteed to fully consume the iterable), adding list() calls where appropriate. It also special-cases "x in range(y)".

to listen on in network-oriented tests has been refined in an effort to
facilitate running multiple instances of the entire regression test suite
in parallel without issue. test_support.bind_port() has been fixed such
that it will always return a unique port -- which wasn't always the case
with the previous implementation, especially if socket options had been
set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
new implementation of bind_port() will actually raise an exception if it
is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
This currently only applies to Windows. This option prevents any other
sockets from binding to the host/port we've bound to, thus removing the
possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
that occurs when a second SOCK_STREAM socket binds and accepts to a
host/port that's already been bound by another socket. The optional
preferred port parameter to bind_port() has been removed. Under no
circumstances should tests be hard coding ports!
test_support.find_unused_port() has also been introduced, which will pass
a temporary socket object to bind_port() in order to obtain an unused port.
The temporary socket object is then closed and deleted, and the port is
returned. This method should only be used for obtaining an unused port
in order to pass to an external program (i.e. the -accept [port] argument
to openssl's s_server mode) or as a parameter to a server-oriented class
that doesn't give you direct access to the underlying socket used.
Finally, test_support.HOST has been introduced, which should be used for
the host argument of any relevant socket calls (i.e. bind and connect).
The following tests were updated to following the new conventions:
test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
test_poplib, test_ftplib, test_telnetlib, test_socketserver,
test_asynchat and test_socket_ssl.
It is now possible for multiple instances of the regression test suite to
run in parallel without issue.
It was only used as a helper in types.py to access types (GetSetDescriptorType and MemberDescriptorType),
when they can easily be obtained with python code.
These expressions even work with Jython.
I don't know what the future of the types module is; (cf. discussion in http://bugs.python.org/issue1605 )
at least this change makes it simpler.
suite as a side-effect of importing the module.
- in test_capi, a thread tried to import other modules
- re.compile() imported sre_parse again on every call.
close() will now raise an IOError if any operations on the file object
are currently in progress in other threads.
Most code was written by Antoine Pitrou (pitrou). Additional testing,
documentation and test suite cleanup done by me (gregory.p.smith).
Fixes issue 815646 and 595601 (as well as many other bugs and
references to this problem dating back to the dawn of Python).
HandlerBException is ignored, and fix one such problem, where it was thrown
during the __del__ method of the previous Popen object.
We may want to find a better way of printing verbose information so it's not
spammy when the test passes.
directory that is not the source directory (ie, one created using
'/path/to/source/configure'.) Leaves this test very slightly degraded in
that particular case, compared to the build-in-sourcedir case, but that case
isn't a particularly strong test either: neither test the actual path that
will be used after installing. There isn't a particularly good way to test
this, and a poor test beats a failing test.
The problem is that when trying to do the second insert, sqlite seems to sleep
for a very long time. Here is the output from strace:
read(6, "SQLite format 3\0\4\0\1\1\0@ \0\0\0\1\0\0\0\0"..., 1024) = 1024

I don't know which version this was fixed in, but 3.2.1 definitely fails.
directory to the directory in which the setup.py script lived (which made
__file__ wrong)
fixed, with test that the script is run in the current directory of the caller
calls threading.currentThread.
The correction somewhat improves the code, but it was close.
Many thanks to the "with" construct, which turns python code into C calls.
I wonder if it is not better to sys.settrace(None) just after
running the __main__ module and before finalization.
When cls is an ABCMeta, every call to isinstance(x, cls)
records type(x) in the cls._abc_cache of cls_abc_negative_cache.
So we clear these caches at the end of the test.
inspect.isabstract() is not the correct test for all ABCs, because there is no @abstractmethod in io.py (why?)
isinstance(cls, ABCMeta) would be more exact, but it fails with an infinite recursion.
So I used a hack to determine whether a class is an ABCMeta.
The true correction would be to turn cls._abc_cache &co into a WeakSet, as py3k does.
But classic classes are not weak referenceable...
Of course, this change should not be merged into the py3k branch.
The moved tests use a local server rather than going out to external servers.
Accepts patch from issue2429.

reliable, but I'm not convinced it is the right solution. We need
to determine if this causes the test to hang on any platforms or do
other bad things.
Even if it gets the test to pass reliably, it might be that we want
to fix this in socket. The socket returned from accept() is different
on different platforms (inheriting attributes or not) and we might
want to ensure that the attributes (at least blocking) is the same
across all platforms.
up after it was joined had a traceback pointing to that thread's (deleted)
target attribute, while the test was trying to check that the target was
destroyed. Big thanks to Antoine Pitrou for diagnosing the race and pointing
out sys.exc_clear() to kill the exception early. This fixes issue 2496.
The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.

to be somewhat accidental (specific to reference counting). When this

the connect would succeed before the timeout occurred. Try using an
address and port that hopefully doesn't exist to ensure we get no response.
If this doesn't work, we can use a public address close to python.org
and hopefully that address never gets taken.

was an exception when calling Popen.__del__
* Always set an alarm handler so the process doesn't exit if the test fails
