Python parser performance optimizations
by Artyom Skrobov Sept. 16, 2016

Sept. 16, 2016

Hello, Back in March, I've posted a patch at http://bugs.python.org/issue26526 -- "In parsermodule.c, replace over 2KLOC of hand-crafted validation code, with a DFA". The motivation for this patch was to enable a memory footprint optimization, discussed at http://bugs.python.org/issue26415 My proposed optimization reduces the memory footprint by up to 30% on the standard benchmarks, and by 200% on a degenerate case which sparked the discussion. The run time stays unaffected by this optimization. Python Developer's Guide says: "If you don't get a response within a few days after pinging the issue, then you can try emailing python-dev(a)python.org<mailto:python-dev@python.org> asking for someone to review your patch." So, here I am. IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

[RELEASE] Python 3.6.0b1 is now available
by Ned Deily Sept. 16, 2016

Sept. 16, 2016

On behalf of the Python development community and the Python 3.6 release team, I'm happy to announce the availability of Python 3.6.0b1. 3.6.0b1 is the first of four planned beta releases of Python 3.6, the next major release of Python, and marks the end of the feature development phase for 3.6. Among the new major new features in Python 3.6 are: * PEP 468 - Preserving the order of **kwargs in a function * PEP 487 - Simpler customization of class creation * PEP 495 - Local Time Disambiguation * PEP 498 - Literal String Formatting * PEP 506 - Adding A Secrets Module To The Standard Library * PEP 509 - Add a private version to dict * PEP 515 - Underscores in Numeric Literals * PEP 519 - Adding a file system path protocol * PEP 520 - Preserving Class Attribute Definition Order * PEP 523 - Adding a frame evaluation API to CPython * PEP 524 - Make os.urandom() blocking on Linux (during system startup) * PEP 525 - Asynchronous Generators (provisional) * PEP 526 - Syntax for Variable Annotations (provisional) * PEP 528 - Change Windows console encoding to UTF-8 (provisional) * PEP 529 - Change Windows filesystem encoding to UTF-8 (provisional) * PEP 530 - Asynchronous Comprehensions Please see "What’s New In Python 3.6" for more information: https://docs.python.org/3.6/whatsnew/3.6.html You can find Python 3.6.0b1 here: https://www.python.org/downloads/release/python-360b1/ Beta releases are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage maintainers of third-party Python projects to test with 3.6 during the beta phase and report issues found to bugs.python.org as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2016-12-05). Our goal is have no changes after rc1. To achieve that, it will be extremely important to get as much exposure for 3.6 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments The next planned release of Python 3.6 will be 3.6.0b2, currently scheduled for 2016-10-03. More information about the release schedule can be found here: https://www.python.org/dev/peps/pep-0494/ -- Ned Deily nad(a)python.org -- []

Microbenchmarks
by Victor Stinner Sept. 15, 2016

Sept. 15, 2016

The discussion on benchmarking is no more related to compact dict, so I start a new thread. 2016-09-15 13:27 GMT+02:00 Paul Moore <p.f.moore(a)gmail.com>: > Just as a side point, perf provided essentially identical results but > took 2 minutes as opposed to 8 seconds for timeit to do so. I > understand why perf is better, and I appreciate all the work Victor > did to create it, and analyze the results, but for getting a quick > impression of how a microbenchmark performs, I don't see timeit as > being *quite* as bad as Victor is claiming. He he, I expected such complain. I already wrote a section in the doc explaining "why perf is so slow": http://perf.readthedocs.io/en/latest/perf.html#why-is-perf-so-slow So you say that timeit just works and is faster? Ok. Let's see a small session: $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 46.7 msec per loop $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 46.9 msec per loop $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 46.9To msec per loop $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 47 msec per loop $ python2 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 36.3 msec per loop $ python2 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 36.1 msec per loop $ python2 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 36.5 msec per loop $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 48.3 msec per loop $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 48.4 msec per loop $ python3 -m timeit -s "d=dict.fromkeys(map(str,range(10**6)))" "list(d)" 10 loops, best of 3: 48.8 msec per loop I ran timeit 7 times on Python 3 and 3 times on Python 2. Please ignore Python 2, it's just a quick command to interfere with Python 3 tests. Now the question is: what is the "correct" result for Python3? Let's take the minimum of the minimums: 46.7 ms. Now imagine that you only ran only have the first 4 runs. What is the "good" result now? Min is still 46.7 ms. And what if you only had the last 3 runs? What is the "good" result now? Min becomes 48.3 ms. On such microbenchmark, the difference between 46.7 ms and 48.3 ms is large :-( How do you know that you ran timeit enough times to make sure that the result is the good one? For me, the timeit tool is broken because you *must* run it many times to workaround its limits. In short, I wrote the perf module to answer to these questions. * perf uses multiple processes to test multiple memory layouts and multiple randomized hash functions * perf ignores the first run, used to "warmup" the benchmark (--warmups command line option) * perf provides many tools to analyze the distribution of results: minimum, maximum, standard deviation, histogram, number of samples, median, etc. * perf displays the median +- standard deviation: median is more reproductible and standard deviation gives an idea of the stability of the benchmark * etc. > I will tend to use perf now that I have it installed, and now that I > know how to run a published timeit invocation using perf. It's a > really cool tool. But I certainly won't object to seeing people > publish timeit results (any more than I'd object to *any* > mirobenchmark). I consider that timeit results are not reliable at all. There is no standard deviation and it's hard to guess how much times the user ran timeit nor how he/she computed the "good result". perf takes ~60 seconds by default. If you don't care of the accuracy, use --fast and it now only takes 20 seconds ;-) Victor

Drastically improving list.sort() for lists of strings/ints
by Elliot Gorokhovsky Sept. 15, 2016

Sept. 15, 2016

Hello all, I am interested in making a non-trivial improvement to list.sort(), but before I put in the work, I want to test the waters and see if this is something the community would accept. Basically, I want to implement radix sort for lists of strings. So list.sort() would detect if it is sorting a list of strings (which is one of the more common things you sort in python) and, if so, use in-place radix sort (see https://xlinux.nist.gov/dads/ HTML/americanFlagSort.html). In-place radix sort is significantly faster for lexicographic sorting than Timsort (or in general any comparison-based sort, since radix can beat the nlogn barrier). If you don't believe that last claim, suppose for the sake of the argument that it's true (because if I actually implemented this I could supply benchmarks to prove it). The idea is the following: in list.sort(), if using the default comparison operator, test the type of the first, middle, and last elements (or something along those lines). If they are all strings, in practice this means the list is very likely a list of strings, so it's probably worth the investment to check and see. So we iterate through and see if they really are all strings (again, in practice it is very unlikely this test would fail). Luckily, this is very, very nearly free (i.e. no memory cost) since we have to iterate through anyway as part of the in-place radix sort (first step is to count how many elements go in each bucket, you iterate through to count. So we would just put a test in the loop to break if it finds a non-string). Additionally, since often one is sorting objects with string or int fields instead of strings or ints directly, one could check the type of the field extracted by the key function or something. Is this something the community would be interested inf? Again, supposing I benchmark it and show it gives non-trivial improvements on existing codebases. Like for example I could benchmark the top 10 packages on pypi and show they run faster using my list.sort(). TL;DR: Should I spend time making list.sort() detect if it is sorting lexicographically and, if so, use a much faster algorithm? Thanks for reading, Elliot

I have no particular usecase in mind. As far as I understand the compact implementation, sets can do it just as well. The original discussion proposed trying to implement it for sets first. Like dict, they would (probably) use less memory, and would usually have a more readable (i.e. less jarring to read) print order.

Code Complexity Survey
by Vard Antinyan Sept. 14, 2016

Sept. 14, 2016

Dear Python developers, We have undertaken a task to assess code complexity triggers and generate recommendations for developing simple and understandable code. Our intension is to share the results with you, developers, so everyone can learn the triggers behind complex software. We need your help for rigorous results. My request to you is - if you get 5-10 min. time, would you please consider to answer the questions of this survey? https://goo.gl/forms/h9WXZ8VSEw7BUyHg1 You are welcome to learn preliminary results through this link: https://www.facebook.com/SoftwareCodeQuality/photos/?tab=album&album_id=163… The results will be shared in a public webpage and everyone possible will be invited to learn and discuss them. Your knowledge and experience is vital for achieving substantial and generalizable results, and your effort is much appreciated!
