[issue18756] os.urandom() fails under high load
Donald Stufft added the comment: haypo: It's been suggested by a number of security professionals that using the OpenSSL random (or really any random) instead of urandom is likely to be a smarter idea. The likelyhood that urandom is broken is far less than any other source of random. This can be seen in the recent issues on the Android platform. This is not to say that there's a reason to believe that OpenSSL is broken currently, but that the chances are higher for it to be than /dev/urandom. An example of when this happened was http://www.debian.org/security/2008/dsa-1571. There's no reason to believe that OpenSSL is wrong right now, but the chances of OpenSSL being wrong are greater than the chances of /dev/urandom being There's been a few threads on twitter about it in light of the Android SecureRandom issue (don't need to read these, just here for reference): - https://twitter.com/tqbf/status/368089082800246784 - https://twitter.com/tqbf/status/367793231808843777 - https://twitter.com/tqbf/status/368089362333827072 I don't think it actually matters if os.urandom or random.SystemRandom is the preferred interface that keeps the FD open but I do believe there should be one implementation that will use the OS source of random and maintain a persistent FD. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18756 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Since that was the only thing that previously could fail, the change leaves nothing that can fail, so the test is not a test.

[issue5527] multiprocessing won't work with Tkinter (under Linux)
James Sanders added the comment: I did a bit more digging and I think I've worked out what is going on. The particular bit of tcl initialization code that triggers the problem if it is run before the fork is Tcl_InitNotifier in tclUnixNotify.c. It turns out there is a known problem with this bit of tcl not being process-safe if tcl was built with threading support (this is discussed at https://bugs.archlinux.org/task/16401, for example). The bug doesn't show up in my 8.5 builds as threading support is off by default, though the debian/ubuntu packages apparently have it switched on. Threading was turned on by default in 8.6, but a recent change to tclUnixNotify.c (discussed at https://issues.apache.org/bugzilla/show_bug.cgi?id=55153#c13 - it should be included in 8.6.1 and 8.5.15) appears to have fixed the whole problem anyway. So hopefully the bug should disappear entirely in future releases of tcl, but for now you can work around it by building tcl without threads, calling exec in between the fork and any use of tkinter in the child process, or not importing tkinter until after the fork. I don't know if there should be a note about this somewhere in the tkinter docs? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5527 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18768] Wrong documentation of RAND_egd function in ssl module
New submission from Vajrasky Kok: import ssl ssl.RAND_egd.__doc__ RAND_egd(path) - bytes\n\nQueries the entropy gather daemon (EGD) on the socket named by 'path'.\nReturns number of bytes read. Raises SSLError if connection to EGD\nfails or if it does provide enough data to seed PRNG. Compare it to documentation about RAND_egd() function from openssl website (https://www.openssl.org/docs/crypto/RAND_egd.html): RAND_egd() and RAND_egd_bytes() return the number of bytes read from the daemon on success, and -1 if the connection failed or the daemon did not return enough data to fully seed the PRNG. Attached the patch to fix the documentation. I am not sure whether we should put the word fully or not.

In the absence of either, you need either to simulate its behavior by doing this: for t in type(a).__mro__: if '__index__' in t.__dict__: return t.__dict__['__index__'](a) Or you can piggyback on an unrelated call that simply causes the C-level PyNumber_Index() to be called: return range(a).stop -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18712 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18771] Reduce the cost of hash collisions for set objects
New submission from Raymond Hettinger: I'm working on a patch for the lookkey() functions in Object/setobject.c. The core idea is to follow the probe sequence as usual but to also check an adjacent entry for each probe (i.e. check table[i mask] as usual and then check table[(i mask) ^ 1] before going on the next probes which are scattered around memory). On modern processors (anything in the last decade), this is likely to reduce the cost of hash collisions and reduce the number of cache lines fetched from memory. + Cache line benefit: improves the odds that the adjacent probe will be on the same cache line, thereby reducing the total number of cache lines fetched. This benefit will work for set insertions as well as set lookups (a partial write to a cache line requires that a full cache line be read prior to writing, so it is helpful if we've just examined another slot on the same cache line). + Parallel execution: because the second lookup has no data dependency on the first lookup, some of its instructions can be executed in parallel by the out-of-order engine. + Reduced loop overhead: the second lookup doesn't require a new computation of the index *i* (we just do a XOR 1), a new perturb shift, a new masking of *i*, or a jump to the top of the loop. In other words, it has all the usual benefits of loop unrolling. - On the downside, even this partial unrolling when increase the total code size which has the negative effect of blowing other code out of the I-cache (typically 32kb). ? I'm unsure whether the additional if-statements will have a net positive or net negative effect on branch prediction rates (positive because each branch can be tracked separately or negative because additional branches use up more space in the branch prediction tables). Once the patch is ready, I'll run CacheGrind to get a better sense of what is happening. -- components: Interpreter Core messages: 195506 nosy: haypo, rhettinger priority: normal severity: normal status: open title: Reduce the cost of hash collisions for set objects type: performance versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18771 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18702] Report skipped tests as skipped
Serhiy Storchaka added the comment: You changed NNTP_CLASS = nntplib.NNTP_SSL, which could potentially fail, to NNTP_CLASS = getattr(nntplib, 'NNTP_SSL', None), which cannot fail. Since that was the only thing that previously could fail, the change leaves nothing that can fail, so the test is not a test. This statement is not a part of a test. It runs at module import time. As you said in msg194907 the failing here will prohibit the running of all tests (even not SSL related). I suggested that you either not add the third param, a default, getattr(nntplib, 'NNTP_SSL') is same as nntplib.NNTP_SSL. And it will break all tests. or that you remove the null test completely. The purpose of this issue is stopping silence skipping tests. If some tests skipped for some reasons it should be reported. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18702 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18712] Pure Python operator.index doesn't match the C version.
Eric Snow added the comment: Couldn't you make use of inspect.getattr_static()? getattr_static(obj.__class__, '__index__').__get__(obj)() getattr_static() does some extra work to get do the right lookup. I haven't verified that it matches _PyType_Lookup() exactly, but it should be pretty close at least. Also, pickle (unfortunately) also does lookup on instances rather than classes for the special methods (issue #16251). -- nosy: +eric.snow ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18712 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18730] suffix parameter in NamedTemporaryFile silently fails when not prepending with a period
Terry J. Reedy added the comment:
'Filename extensions' are a proper subset of 'suffixes'.
https://en.wikipedia.org/wiki/Filename_extension
Dan 'solutions' indicates that he thinks that the two sets are or should be the
same, which they are not. The only thing that is DOS/Windows specific is its
more special treatment of '.'. That said, I can see how a Windows user might
be confused by the following awkward sentence.
If 'suffix' is specified, the file name will end with that suffix,
otherwise there will be no suffix.
as 'no suffix' is easily read as 'no extension. The manual, but not the
docstring, addresses the possible confusion by adding
mkstemp() does not put a dot between the file name and the suffix;
if you need one, put it at the beginning of suffix.
I think the prefix sentence is also a bit awkward.
If 'prefix' is specified, the file name will begin with that prefix,
otherwise a default prefix is used.
I think both parameters should be explained in both docstring and doc with one
shorter and clearer entry.
The file name will begin with *prefix* (default 'tmp') and end with *suffix*
(default ''). The is no automatic addition of a period ('.') before the suffix.

[issue18730] suffix parameter in NamedTemporaryFile silently fails when not prepending with a period
Serhiy Storchaka added the comment: I don't think any explanation is needed. A docstring should be short, we can't duplicate a manual in it. The mentioning suffix default is redundant because it already exposed in the function signature. The mentioning prefix default adds duplication. The purpose of introducing of the template attribute is get rid of such duplication. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18730 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18702] Report skipped tests as skipped
Serhiy Storchaka added the comment: Actually you should call parent's setUpClass at the and of declared setUpClass. Therefore you need 4 nontrivial lines instead of 1. The test will fail in setUpClass() in any case because parent's setUpClass() uses NNTP_CLASS. There are no behavior difference between this variants, the variant with getattr just is shorter. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18702 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18730] suffix parameter in NamedTemporaryFile silently fails when not prepending with a period
Terry J. Reedy added the comment:
It would be fine with me to shorten the suggestion and not repeat the defaults.
They are currently in both doc and docstring, but with *more* words than I used.
The file name will begin with *prefix* and end with *suffix*. There is no
automatic addition of a period ('.') before the suffix.
The explanation of . is already in the doc in a wordier form (too wordy in my
view). The above is much shorter than what is currently in the docstring.

[issue18771] Reduce the cost of hash collisions for set objects
Raymond Hettinger added the comment: Serhiy, I've posted a patch so you can examine the effects in detail. For something like set(range(n)), I would expect no change because the dataset is collision free due to Tim's design where hash(someint)==someint. That said, I'm trying to optimize the general case and don't really if rare cases are modestly slowed. The new code only kicks in when there is a collision. The logic for the initial probe is unchanged. The idea is to pickup some of the cache locality benefits of collision resolution by separate chaining, but not incurring the 100% malloc typically associated with chaining. When adjacent entries are in the same cache-line, the cost of the extra adjacent probe is much cheaper (nearly zero) than a probe somewhere else in memory. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18771 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18747] Re-seed OpenSSL's PRNG after fork
STINNER Victor added the comment: openssl_prng_atfork3.patch: Why not using seconds (only micro or nanoseconds) in the seed? Add a few more bits should not reduce the entropy. OpenSSL does hash all these bytes anyway. +#if 1 +fprintf(stderr, PySSL_RAND_atfork_child() seeds %i bytes in %i\n, +(int)sizeof(seed), seed.pid); +#endif This should be removed from the final patch ;-) The patch is specific to pthread. Do we need something similar on Windows. Windows has no fork, but I don't know if OpenSSL CPRNG state can be inherited somehow? Does Python support other platforms (other than pthread or Windows)? Instead of using pthread_atfork(), we can add an hook in the Python binding of OpenSSL checking the pid. I don't know which functions should be modified. ssl.RAND_bytes() is probably not enough :-) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18747 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17810] Implement PEP 3154 (pickle protocol 4)
Nick Coghlan added the comment: Potentially relevant to this: we hope to have PEP 451 done for 3.4, which adds a __spec__ attribute to module objects, and will also tweak runpy to ensure -m registers __main__ under it's real name as well. If pickle uses __spec__.name in preference to __name__ when __spec__ is defined, then objects defined in __main__ modules run via -m should start being pickled correctly. -- nosy: +ncoghlan ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17810 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
