[issue20517] Support errors with two filenames for errno exceptions
Larry Hastings added the comment: Serhiy: I'm not sure if it's the language barrier, but that came across kind of mean. It's not that I can do whatever I want as release manager, but that I have the say in whether something is a bug fix or a new feature, which is how we decide whether or not something is allowed into Python after feature freeze. This issue has been on my radar for a while (originally #16074). But I wasn't paying strong attention to it. Nobody in that issue came up with a solution I liked. Finally when you posted your patch I said ugh, can't we do better and had to think about it before I realized we should just display both filenames. If somebody had posted a patch with that two months ago I would have happily accepted it and we wouldn't be having this conversation now. Vajrasky: My goal is that Python is nicer to use than PHP or Perl. And it's more than a month before 3.4 final is scheduled to be released. This patch is a pretty mechanical change--create new function, accept extra parameter, make the tuple one entry longer. I don't expect it to be destabilizing. However, I *was* hoping that one of the original authors of the code in question would come forth and say a) whether or not they think it's a good idea in general, and b) if they think the specific approach is fine. The patch is a bit stalled because of higher-priority Argument Clinic changes. I could post a partial patch if someone wanted to pick it up and finish it. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20517 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Actually that was Vajrasky's patch, and that was extended version of your patch. I asked you not because you are release manager, but because you are the author of the code and original patch. I agree that support errors with two filenames is better solution than remove ambiguous filename attribute, but there is no much time left and we still don't have a patch. Vajrasky's patch is alternate variant for 3.4 in case when better patch will not be ready and is only solution for 3.3 (if we decide to fix this in 3.3). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20517 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20526] python: Modules/gcmodule.c:379: visit_decref: Assertion `((gc)-gc.gc_refs (1)) != 0' failed.
New submission from STINNER Victor:
While trying to reproduce a race condition in asyncio, I got an assertion error
from the Python garbage collector at exit. It's not easy to reproduce the
issue: run attached script on Python 3.4 compiled in debug mode (to get
assertions) and press CTRL+c twice. It looks like the bug occurs more often
after at least 400 runs.
The Future class of the asyncio may store an exception in its private
Future._exception attribute. An exception stores a traceback. I don't know if
it's related.

[issue20527] multiprocessing.Queue deadlocks after “reader” process death
New submission from OscaTutenchamon:
I've experienced that queue can be deadlocked for reading when:
1. The reader process is using `get` with timeout 0:
self.queue.get(timeout=3)
2. reader dies while `get` is blocking due to timeout.
After that queue's `_rlock` is never being released so reading becomes
impossible.
Application demonstrating the problem.
I create two child processes Worker (putting into queue) and Receiver
(getting from queue). Also parent process periodically checks if his children
are alive and starts new child if needed.

procname.setprocname('Receiver')
while True:
try:
msg = self.queue.get(timeout=3)
print ' `{}`, queue rlock: {}'.format(
msg, self.queue._rlock)
except multiprocessing.queues.Empty:
print ' EMPTY, Queue rlock: {}'.format(
self.queue._rlock)
pass
class Worker(multiprocessing.Process):
''' Puts into queue with 1 sec sleep '''
def __init__(self, queue):
multiprocessing.Process.__init__(self)
self.queue = queue
def run(self):
procname.setprocname('Worker')
while True:
time.sleep(1)
print 'Worker: putting msg, Queue size: ~{}'.format(
self.queue.qsize())
self.queue.put('msg from Worker')
if __name__ == '__main__':
queue = multiprocessing.Queue()
worker = Worker(queue)

if not worker.is_alive():

[issue20528] fileinput module will read whole file into memory when using fileinput.hook_encoded due to codecs.StreamReader.readlines
New submission from Gunnar Aastrand Grimnes:
When reading large files with fileinput, it will work as expected and only
process a line at a time when used normally, but if you add an hook_encoded
openhook it will read the whole file into memory before returning the first
line.
Verify by running this program on a large text file:
import fileinput
for l in fileinput.input(openhook=fileinput.hook_encoded('iso-8859-1')):
raw_input()
and check how much memory it uses. Remove the openhook and memory usage goes
down to nothing.
The problem is that fileinput calls readlines with a size-hint and in
codecs.StreamReader, readlines explicitly ignores this hint and reads all lines
into memory.
http://bugs.python.org/issue20501 is open for fixing up the documentation for
fileinput, but a fix would also be nice.
I see two options:
1. As suggested by r.david.murray: Give us a way of signaling to fileinput that
it should not use readlines, for instance by setting buffer=None
2. Fix the codecs module to allow StreamReader to respect the hint if given.
Although the comment there says it's no efficient way to do this, at least an
inefficient way would be better than reading a possibly infinite stream in. A
simple solution would be to repeatedly call readline. A more complicated
solution would be to read chunks from the stream, and then encode them, just
like the readline method does.
BTW - this issue is py2.7 only, I tested a file object from io.open with
encoding in 3.3 and it supports readlines just fine.

This behavior should be controllable (I'm not even sure they *can* be turned on if python is not compiled in debug mode). I don't see resource warnings mentioned in the TextTestRunner docs that mention the other warning controls. It also seems like perhaps there should be a way to control warnings from the unittest command line. So I'd say there are some improvements that can be made here, but the basic behavior is working as intended. -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20529 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Here is the updated patch for gc module.
Some functions that can not be converted:
- set_threshold(threshold0, [threshold1, threshold2])
Don't know what default value to give to threshold1, threshold2.
static struct gc_generation generations[NUM_GENERATIONS] = {
/* PyGC_Head, threshold, count */
{{{GEN_HEAD(0), GEN_HEAD(0), 0}}, 700,0},
{{{GEN_HEAD(1), GEN_HEAD(1), 0}}, 10, 0},
{{{GEN_HEAD(2), GEN_HEAD(2), 0}}, 10, 0},
};
- collect([generation])
Don't know what default value to give to generation.
int genarg = NUM_GENERATIONS - 1;
I don't think we can use expression in signature.
- get_referrers and get_referents
Don't know what signature to use for functions that can accept any number of
arguments.

[issue20531] TypeError in e-mail.parser when non-ASCII is present
New submission from Jason R. Coombs: As reported in https://bitbucket.org/dholth/wheel/issue/104, the email.parser no longer accepts Unicode content as it did in 3.3. I searched the What's New and module documentation, but found no indication that this behavior is no longer supported, so it appears to be a regression. If it's an intentional change, the behavior should be documented in one of the aforementioned documents. Consider this simple test case: # -*- coding: utf-8 -*- import email.parser meta = Header: ☃ email.parser.Parser().parsestr(meta) Run that on Python 3.3.3 or Python 2 and it executes silently.

That is, if you pretend the message is a string, it will happily output
it as a string, including perhaps your writing the output to a file as
utf-8...but it will *NOT* be a valid email message, since it will have
non-ascii data in it with no specified CTE.

[issue12691] tokenize.untokenize is broken
Gareth Rees added the comment: I did some research on the cause of this issue. The assertion was added in this change by Jeremy Hylton in August 2006: https://mail.python.org/pipermail/python-checkins/2006-August/055812.html (The corresponding Mercurial commit is here: http://hg.python.org/cpython/rev/cc992d75d5b3#l217.25). At that point I believe the assertion was reasonable. I think it would have been triggered by backslash-continued lines, but otherwise it worked. But in this change http://hg.python.org/cpython/rev/51e24512e305 in March 2008 Trent Nelson applied this patch by Michael Foord http://bugs.python.org/file9741/tokenize_patch.diff to implement PEP 263 and fix issue719888. The patch added ENCODING tokens to the output of tokenize.tokenize(). The ENCODING token is always generated with row number 0, while the first actual token is generated with row number 1. So now every token stream from tokenize.tokenize() sets off the assertion. The lack of a test case for tokenize.untokenize() in full mode meant that it was (and is) all too easy for someone to accidentally break it like this. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12691 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20527] multiprocessing.Queue deadlocks after “reader” process death
Richard Oudkerk added the comment: This is expected. Killing processes which use shared locks is never going to end well. Even without the lock deadlock, the data in the pipe would be liable to be corrupted if a processes is killed while putting or getting from a queue. If you want to be able to reliably recover when a related process dies then you would be better off using one-to-one pipes for comunication -- although that would probably mean substantial redesign. -- resolution: - wont fix stage: - committed/rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20527 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20537] logging exc_info parameter should accept exception instances
New submission from Yury Selivanov: A bunch of logging methods accept optional parameter exc_info, that is supposed to be either 'True' or a tuple of three elements (type, exc, tb). If, however, someone passes an actual exception instance, Logger._log function will interpret it as True and get the current exception from sys.exc_info, ignoring the passed exception completely. Attached is a patch that fixes this: if exc_info is an instance of BaseException, Logger._log creates the tuple out of it automatically. -- files: logging_01.patch keywords: patch messages: 210428 nosy: vinay.sajip, yselivanov priority: normal severity: normal status: open title: logging exc_info parameter should accept exception instances type: enhancement versions: Python 3.4, Python 3.5 Added file: http://bugs.python.org/file33950/logging_01.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20537 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19662] smtpd.py should not decode utf-8
R. David Murray added the comment:
Unfortunately I did not get to this before the 3.4 beta release, so no, it
won't be fixed in 3.4.
You can work around it by overriding collect_incoming_data in your subclass and
doing data.decode('ascii', 'surrogateescape') instead of str(data, 'utf-8'),
and then doing mydata.encode('ascii', 'surrogateescape') at the point where you
want to turn the data back into binary.

[issue20530] Change the text signature format (again) to be more robust
Larry Hastings added the comment: Thanks for noticing the (/), that's fixed. Yes, the signature for type() was wrong. type() can accept either one parameter or three parameters--in other words, it uses optional groups. And we can't represent optional groups in an inspect.Signature signature in 3.4. And I assert that it's better to not have a signature than to have a wrong signature. So I've removed it. I'm interested in your other minor stuff. I'll try and leave the patch alone this time :) If you apply diff #2, you'll have a failure in test_inspect. This is because there's a bug in inspect.Signature that it would take too long to fix, and I have to leave right now-ish. I changed the tests so they expect the correct results, but they get the wrong results at the moment. Hopefully we can fix this really quickly. -- Yuri: This change uncovered a lurking bug in inspect.Signature that I'm hoping you can fix. I could probably figure it out given enough time but I won't have time to look at it for about 24 hours. Now that type() doesn't have a signature, I have discovered that some of the logic in Signature is wrong. class C(type): pass print(str(inspect.signature(C))) The signature of that *should* be the same as type(). But inspect.signature() reports the signature as '()'. The reason this happens: inspect.Signature gets to the for base in mro case for handling classes. The first base it tries is type(), but type() doesn't have a public signature so it keeps going. The next class in the MRO is object(), which has a signature of (), so it uses that. It shouldn't keep going! I'm 99% certain that the first entry in the MRO will always be callable. (Is it possible to have a type in Python that isn't callable?) I *think* what it should do is: simply try the first entry in the MRO. If that has a signature, return it. If it doesn't have a signature, inspect.Signature should raise ValueError. I also *think* that all the code after this comment: # No '__text_signature__' was found for the 'obj' class. should be removed. If C doesn't define its own __new__ or __init__, and its base class doesn't have __call__, then the signature of C *is* the signature of its base class. If inspect.Signature can't read that signature, then it can't return a signature for C. -- Added file: http://bugs.python.org/file33953/larry.even.newerer.signature.syntax.2.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20530 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
