[issue10644] socket loses data, calling send()/sendall() on invalid socket does not report error and returns all bytes as written
New submission from diekmann diekm...@in.tum.de: Calling send()/sendall() on an invalid socket does not report an error and returns all bytes as written. Thus, all bytes written to the socket are lost and the application is not informed about that and treats the bytes as successfully sent. The bytes given to the socket are silently lost, this cannot be recovered. The attached file includes an example to reproduce this problem. I defined an invalid socket, when the other side of the connection has closed the connection. Steps to reproduce (see attached file for python implementation): 1) Create listening socket 2) let client connect to it 2.1) send something to the client (optional step) 3) Client terminates connection (now the socket on the server side is invalid) 4) Server calls send/sendall --- No Error here, but everything is lost 5) Server calls send/sendall again (Now we get the required error) -- components: Library (Lib) files: socketbug.py messages: 123534 nosy: diekmann priority: normal severity: normal status: open title: socket loses data, calling send()/sendall() on invalid socket does not report error and returns all bytes as written type: behavior versions: Python 3.1 Added file: http://bugs.python.org/file19969/socketbug.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10644 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10641] kill_python sometimes fails to kill processes on buildbots
David Bolen db3l@gmail.com added the comment: To kill python_d.exe, you should use kill_python_d.exe instead of kill_python.exe. Crud, I thought I did. Well, ok, so can't trust this test. Could you post the buildbot log url? I think this is the last build in the sequence that was failing until I killed the processes: http://www.python.org/dev/buildbot/all/builders/x86%20Windows7%203.x/builds/2297 ... the processes had been around for maybe 45 hours at that point, but I can't find the last working run in the waterfall display (I get back to 2252 and then it sort of goes blank). Maybe the main problem is just the sequencing ... the fact that kill_python is only used at the start of a build (but after the svn step) and not during the clean step at the end of a test run? In this case since the svn step was failing it probably never got as far as running kill_python[_d]. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10641 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10626] Bad interaction between test_logging and test_concurrent_futures
Vinay Sajip vinay_sa...@yahoo.co.uk added the comment: I will take a look at test_logging tidying up after itself, though the intention is to leave things as they were found (this is done in setUp/tearDown, and if it doesn't tidy up properly, that would be a bug). As already explained in logging's documentation, there is no problem with just getting a logger and logging to it, BUT the top-level logger in any library package (and that includes stdlib, too) should have a NullHandler instance added to avoid the no handlers could be found for logger XXX message. This latter, one-off message is only there to guard against mis-configuration. Re. Nick's comments about using logging in the stdlib - I'm not sure the reason he states is the reason for lack of traction, I think it's more to do with inertia. I will post separately on python-dev about use of logging in the stdlib itself, to see what specific obstacles stdlib maintainers see in the use of logging in their own modules. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10626 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2799] Remove _PyUnicode_AsString(), rework _PyUnicode_AsStringAndSize(), add PyUnicode_AsChar()
Julian Andres Klode j...@jak-linux.org added the comment:
The problem I see here is that there is no public way to simply get a C string
from a unicode object similar to PyBytes_AsString() for bytes. That's bad
because we don't want to rewrite the whole code to duplicate strings all the
time and free every string we get from a MyPyUnicode_AsString() like function.
I used the following, but this clearly has a memory leak:
static const char *MyPyUnicode_AsString(PyObject *op) {
PyObject *bytes = PyUnicode_AsEncodedString(op,0,0);
return bytes ? PyBytes_AS_STRING(bytes) : 0;
}
I now use the following which has no memory leak, but needs an internal
function (I would use _PyUnicode_AsString, but I need Python 2.X compatibility
as well):
static const char *MyPyUnicode_AsString(PyObject *op) {
PyObject *bytes = _PyUnicode_AsDefaultEncodedString(op, 0);
return bytes ? PyBytes_AS_STRING(bytes) : 0;
}
So could something be done about this?

As FAT does not support links anyways, there would be no issue with potential st_ino issues there as we wouldn't be comparing them for any reason.

I am attaching a revised version of the patch which also includes some tests.
Interestingly, the issue in syslog module is a regression from 3.1
introduced in r80401. Although it is not a crasher, I don't think it was
intentional because although openlog() is happy to accept NULL for indent,
the error from _PyUnicode_AsString() would have to be cleared if the intent
was to ignore undecodable indent.
Some notes:
* Rather than just patching in error handling code, please consider
removing use of those APIs and replace their calls with something
more appropriate, e.g. using a parser API.
* When ignoring errors from the API, you have to clear the exception.
This is missing in a couple of places in the patch, e.g. in pyexpat.c
* Please also remove hacks like these:
+#define CMP PyUnicode_CompareWithASCIIString
+if (CMP(nameobj, entity) == 0)
+res = self-entity;
+else if (CMP(nameobj, target) == 0)
+res = self-target;
+else if (CMP(nameobj, version) == 0) {
+return PyUnicode_FromFormat(
+Expat %d.%d.%d, XML_MAJOR_VERSION,
XML_MINOR_VERSION, XML_MICRO_VERSION);

Martin v.

Well, if MingW could use the VS project files, that would be fine with me as well... We need *some* build procedure. Just being able to compile the source files is not maintainable. It would be a nice to have. But there is one thing: The patch in its current form is trivial and next to impossible to break anything, yet I'm sure it's useful for a number of people. It's a result of work done within the company I'm working for. Submitting the patch does not have an immediate benefit for my company, it only will save me a (short!) amount of time because I will not to have to re-apply the patch for every new Python release.

[issue10648] Extend peepholer to reverse loads or stores instead of build/unpack
Raymond Hettinger rhettin...@users.sourceforge.net added the comment:
Thanks for the patch. I had looked at this long ago when I first added the
ROT2 optimization and the ROT3/ROT2 optimization. It wasn't included because
it wasn't worth the added complexity in the peepholer logic and because there
were concerns about executing internally in a different order than specified by
the code.
Since LOAD_NAME and LOAD_GLOBAL are subject to user control, changing their
order of evaluation causes a visible change in semantics. For example, the
following result is different than before the patch.
class Dict(dict):
... def __getitem__(self, key):
... print(key)
... return dict.__getitem__(self, key)
...
ns = Dict()
exec('c=1; d=2; a,b=c,d', globals(), ns)
d
c
For the most part, I'm not too excited about the patch because
* it is limited to very simple cases that already have some optimization
* it needs to be limited even further to be semantically neutral
* it adds complexity to a part of the peepholer that is already a bit too
complicated (the more peephole assumptions we make, the harder it is to
maintain, especially when opcodes are added, deleted, or changed).
* changing order of execution starts to venture into territory that we've
stayed away from (on purpose).
