[issue19445] heapq.heapify is n log(n), not linear
New submission from Blaise Gassend: The documentation for heapq.heapify indicates that it runs in linear time. I believe that this is incorrect, and that it runs in worst case n * log(n) time. I checked the implementation, and there are indeed n _siftup operations, which each appear to be worst case log(n). One example of the documentation pages that are wrong. http://docs.python.org/3.4/library/heapq.html#heapq.heappush -- assignee: docs@python components: Documentation messages: 201712 nosy: Blaise.Gassend, docs@python priority: normal severity: normal status: open title: heapq.heapify is n log(n), not linear versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19445 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19447] py_compile.compile raises if a file has bad encoding
New submission from Bohuslav Slavek Kabrda: If py_compile.compile is used on a file with bad encoding (e.g. Lib/test/bad_coding2.py), the function raises even if doraise=False is passed. I'm attaching a patch that fixes this in 3.3 - I haven't tried on 3.4 yet and the code has changed, so I'm not sure it's problem there. (Background: During RPM build of Python 3 in Fedora, we use py_compile.compile to make sure all files are properly compiled and have newer timestamps. We use 'find' to get all *.py files under 'python3.3/' and then xargs to pass the files to Python script that compiles them. If one of the files causes py_compile.compile to raise, the rest doesn't get compiled.) -- components: Build files: 00186-dont-raise-from-py_compile.patch keywords: patch messages: 201721 nosy: bkabrda priority: normal severity: normal status: open title: py_compile.compile raises if a file has bad encoding versions: Python 3.3 Added file: http://bugs.python.org/file32422/00186-dont-raise-from-py_compile.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19447 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19444] mmap.mmap() allocates a file descriptor that isn't CLOEXEC
Robert Merrill added the comment: I'm adding Library again because I think the current behavior is a bug and should be fixed in the 2.7 tree. Perhaps the documentation in older versions should be updated mmap.mmap should always set the FD_CLOEXEC flag on the descriptor that it gets from dup(). I don't see why we wouldn't do this, because if we are calling exec(), we are blowing away all python state, and only the mmap object should be using this file descriptor (since its existence is hidden from the user). Users should not be depending on the old behavior, because the interface which is presented to them gives them no indication that this fd even exists. Users are probably expecting the proposed behavior, because anyone who has worked with unix file descriptors in C would not expect: fd = os.open(...) mmap = mmap.mmap(fd, size) # do some stuff os.close(fd) To result in an extra inheritable fd still being there. Nothing in the documentation indicates that this would happen, either. -- components: +Library (Lib) versions: -Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19444 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19449] csv.DictWriter can't handle extra non-string fields
New submission from Tomas Grahn:
When csv.DictWriter.writerow is fed a dict with extra fieldnames (and
extrasaction='raise') and any of those extra fieldnames aren't strings, a
TypeError-exception is thrown. To fix the issue; in csv.py, edit the line:
raise ValueError(dict contains fields not in fieldnames: + ,
.join(wrong_fields))
to:
raise ValueError(dict contains fields not in fieldnames: + ,
.join(repr(wrong_field) for wrong_field in wrong_fields))
Attached is a patch that fixes the problem (works in both 2.6 and 2.7, I
haven't tried anything else).
Here is a simple test to demonstrate the problem:
import cStringIO, csv
sio=cStringIO.StringIO()
writer=csv.DictWriter(sio, [foo, bar])
writer.writerow({1:hello, 2:world})

The proposed solution (to upgrade sqlite) is not possible on Windows as it

So please update the bundled sqlite version where this bug is solved.

[issue19451] urlparse accepts invalid hostnames
New submission from Daniele Sluijters: Python 2's urlparse.urlparse() and Python 3's urllib.parse.urlparse() accept URI/URL's with underscores in the host/domain/subdomain. I believe this behaviour to be incorrect. A distinction needs to be made between DNS names and Uniform Resource Locators and Identifiers, urlparse is supposed to deal with the latter (correct me if I'm wrong). According to RFC 2181 section 11 on the syntax of DNS names the use of the underscore is allowed and in use around the internet, especially in TXT and SRV records. However, RFC 1738 on Uniform Resource Locators section 3.1 (and its updates) always define the 'hostname' part of the URL as being: Such a name consists of a sequence of domain labels separated by ., each domain label starting and ending with an alphanumeric character and possibly also containing - characters. On top of that, RFC 2396 on URI's section 3.2.2: Hostnames take the form described in Section 3 of [RFC1034] and Section 2.1 of [RFC1123]: a sequence of domain labels separated by ., each domain label starting and ending with an alphanumeric character and possibly also containing - characters. The underscore is never mentioned as being a valid character nor do any of the references in the RFC's as far as I've been able to see. Languages implementations vary: * Ruby URI.parse does not allow for underscores in domain labels. * Perl URI and URI::URL allow for underscores. * java.net.uri treats the underscore as an illegal character in the domain part. * org.apache.http.httphost since 4.2.3 treats the underscore as an illegal character in the domain part. Httpd's: * Apache: Seems to tolerate underscores but there's been a whole discussion about this on the mailing lists. * nginx: Matches a server_name of '_' to 'any invalid domain name'. It seems to accept server_names with underscores in them but the behaviour is currently unknown to me. Browsers: * IE cannot write cookies since IE 5.5 if host or subdomain part includes an underscore. * Just about every other browser is fine with it. Please note that I'm only talking about the host/domain/subdomain part of URI's and URL's, something like http://en.wikipedia.org/wiki/12-hour_clock is perfectly valid and should parse. -- components: Library (Lib) messages: 201730 nosy: daenney, orsenthil priority: normal severity: normal status: open title: urlparse accepts invalid hostnames type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19451 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

On Py 2.7.5 (windows7, x64, 4GB ram) this program slowed down obviously after
passing 1,000,000 adds and never completed or raised an exception.
What is the exception? How much free memory do you have? If Python has not
enough memory, Windows will probably starts to move memory to the disk and the
system will becomes slower and slower.

Nikolaus Rath added the comment: I agree that OrderedDict is more a dict than a list, but it is not clear to me why this means that it cannot extend a dict's functionality in that respect. OrderedDict already adds functionality to dict (preserving the order), so why shouldn't it also allow changes during iteration? I think these two things actually come together quite naturally, since it is the existence of an ordering that makes the behavior under changes during iteration well defined.

[issue19453] pydoc.py doesn't detect IronPython, help(foo) can hang
New submission from David Evans:
The pager functions used by help() in StdLib's pydoc.py don't detect IronPython
correctly and the result is a lack of functionality or in some cases a hang.
This is similar to issue 8110 in that the code attempts to detect windows with
a check for win32 from sys.platform and needs to check for cli as well to
detect IronPython running on mono on linux/mac os or on windows.
My naive change to workaround the problem was to add the two line test for
cli amidst getpager() here:
if sys.platform == 'win32' or sys.platform.startswith('os2'):
return lambda text: tempfilepager(plain(text), 'more ')
if sys.platform == 'cli':
return plainpager # IronPython
if hasattr(os, 'system') and os.system('(less) 2/dev/null') == 0:
return lambda text: pipepager(text, 'less')
That two line addition allowed basic function and prevents the hang though
maybe there is a better pager type that would work on IronPython. In our linux
and windows tests though neither the tempfilepager nor pipepager would function
on either platform.
I submitted the report to the IronPython issues tracker and someone there
suggested posting the patch here.

[issue19414] OrderedDict.values() behavior for modified instance
Ethan Furman added the comment: Firstly, you're not copying the entire dict, just its keys. [1] Secondly, you're only copying the keys when you'll be adding/deleting keys from the dict. Thirdly, using the list idiom means you can use OrderedDicts, defaultdicts, dicts, sets, and most likely any other mapping type the same way, whereas if you make OrderedDict special in this area you've locked out the other types. In my opinion the differences in OrderedDict should be limited to what is necessary to make a dict ordered. The ability to insert/delete keys while iterating is not necessary to maintaining an order, and the break from other dicts doesn't add enough value to make it worth it. So, yes, the short answer is because Python's other similar types don't do it that way, OrderedDict shouldn't either. [1] If the dict is large, collect the to_be_deleted keys in a separate list and remove them after the loop. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19414 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19443] add to dict fails after 1,000,000 items on py 2.7.5

However, the program did not stop or raise an exception, which is a concern. The size of the dict was 1.6 GB at that level. My current suspicion is that Windows is not doing a good job of pushing memory already allocated by the process to the virtual file system as the process continues to request more memory.

[issue19063] Python 3.3.3 encodes emails containing non-ascii data as 7bit
R. David Murray added the comment: msg.as_string should not be producing a CTE of 8bit. I haven't looked at your patch so I don't know what you mean by having as_string produce 8bit data, but it can't be right :) To clarify: as_string must produce valid unicode data, and therefore *cannot* have any 8bit data in it. Unicode is not an 8bit channel (in SMTP terms) it is a 7bit channel (ie: restricted to ASCII). The *decoded* version of the message can have non-ASCII in it, but as_string is producing an *encoded* version. The CTE applies only to an encoded version. It gets a little confusing because in Python we are used to 'decoding' to unicode and 'encoding' to bytes, but in the email package we also sometimes 'encode' to ASCII but use unicode strings to store it. If we didn't have to maintain backward compatibility it would probably be better to just drop as_string :) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19063 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Nikolaus Rath added the comment: Hmm. I see your point. You might be right (I'm not fully convinced yet though), but this bug is probably not a good place to go into more detail about this. So what would be the best way to fix the immediate problem this was originally about? Raise a RuntimeError (as Armin suggested), or just end the iteration? Note that RuntimeError would only be raised when the current element is removed from the dict, and the ordered dict would still tolerate other kinds of modifications. Both variants would also be a change from previous behavior (were removing the current elements works as long as you do not remove the next one as well). The minimally intrusive change would be to skip over elements that have been removed, but that comes at the expense of an additional membership test in each iteration. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19414 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17134] Use Windows' certificate store for CA certs
Christian Heimes added the comment:
Here is a simplified version of my patch with doc updates.
Changes:
- Different functions for certs and CRLs: enum_certificates() / enum_crls()
- encoding is now a string ('x509_asn' or 'pkcs_7_asn')
- for certificates trust information is either a set of OIDs or True. The OIDs
can be interpreter with the new functions #19448.
Both functions are intended to be low level interfaces to Window's cert store.

[issue19457] test.test_codeccallbacks.CodecCallbackTest.test_xmlcharrefreplace_with_surrogates() and test.test_unicode.UnicodeTest.test_encode_decimal_with_surrogates() loaded from *.pyc files fail wi
New submission from Arfrever Frehtes Taifersar Arahesis:
test.test_codeccallbacks.CodecCallbackTest.test_xmlcharrefreplace_with_surrogates()
and test.test_unicode.UnicodeTest.test_encode_decimal_with_surrogates() fail
with Python supporting wide unicode, when they have been loaded from *.pyc
files (test_codeccallbacks.pyc, test_unicode.pyc).
(This bug can be reproduced when running `make test`, which runs test suite
twice, firstly with *.pyc files initially absent.)
This bug is a regression in 2.7.6rc1. These tests are absent in 2.7.5. These
tests were added in 719ee60fc5e2.

[issue19063] Python 3.3.3 encodes emails containing non-ascii data as 7bit
R. David Murray added the comment: cte base64 I think (see below). Basically, set_payload should be putting the surrogateescape encoded utf-8 into the _payload (which it should now be doing), and probably calling set_charset. The cte will at that point be 8bit, but when as_string calls Generator, it will get converted to 7bit clean by doing (I think) a base64 encode and emitting that as the CTE. I have to look through the code to remind myself how it all works, which I haven't had time for yet, which is why I haven't tried to make a fix myself yet. (Yes, this is poor design, but we are dealing with a long line of legacy code and API here...) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19063 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
