About Python Developer Testsuites
by Arsalan Javeed (Student) June 19, 2015

June 19, 2015

Dear Concerned, I am using python v.2.7.1 for my research work in software testing. I have already downloaded the source codes and found the built-in testsuites for running on the build. However, i was wondering if by any chance are there any testsuites which exist that are primarily meant for* developers* of the source code which can be used before releasing a build, for instance smoke testsuite/regression testsuites, besides the one already distributed with source code. If such developer … [View More]

Obtaining stack-frames from co-routine objects
by Ben Leslie June 14, 2015

June 14, 2015

Hi all, Apologies in advance; I'm not a regular, and this may have been handled already (but I couldn't find it when searching). I've been using the new async/await functionality (congrats again to Yury on getting that through!), and I'd like to get a stack trace between the place at which blocking occurs and the outer co-routine. For example, consider this code: """ async def a(): await b() async def b(): await switch() @types.coroutine def switch(): yield coro_a = a() … [View More]

What were the complaints of binary code programmers that not accept Assembly?
by françai s June 12, 2015

June 12, 2015

Quote from: http://worrydream.com/dbx/ <http://www.google.com/url?q=http%3A%2F%2Fworrydream.com%2Fdbx%2F&sa=D&sntz=…> Reactions to SOAP and Fortran Richard Hamming -- The Art of Doing Science and Engineering, p25 (pdf book) In the beginning we programmed in absolute binary... Finally, a Symbolic Assembly Program was devised -- after more years than you are apt to believe during which most programmers continued their heroic absolute binary programming. At the time [… [View More]the assembler] first appeared I would guess about 1% of the older programmers were interested in it -- using [assembly] was "sissy stuff", and a real programmer would not stoop to wasting machine capacity to do the assembly. Yes! Programmers wanted no part of it, though when pressed they had to admit their old methods used more machine time in locating and fixing up errors than the [assembler] ever used. One of the main complaints was when using a symbolic system you do not know where anything was in storage -- though in the early days we supplied a mapping of symbolic to actual storage, and believe it or not they later lovingly pored over such sheets rather than realize they did not need to know that information if they stuck to operating within the system -- no! When correcting errors they preferred to do it in absolute binary. FORTRAN was proposed by Backus and friends, and again was opposed by almost all programmers. First, it was said it could not be done. Second, if it could be done, it would be too wasteful of machine time and capacity. Third, even if it did work, no respectable programmer would use it -- it was only for sissies! John von Neumann's reaction to assembly language and Fortran John A.N. Lee, Virginia Polytechnical Institute John von Neumann, when he first heard about FORTRAN in 1954, was unimpressed and asked "why would you want more than machine language?" One of von Neumann's students at Princeton recalled that graduate students were being used to hand assemble programs into binary for their early machine. This student took time out to build an assembler, but when von Neumann found out about it he was very angry, saying that it was a waste of a valuable scientific computing instrument to use it to do clerical work. Because 1% of the older programmers that did not accept to use Assembly changed their minds about the Assembly? Because the older programmers think that using [assembly] was "sissy stuff", and a real programmer would not stoop to wasting machine capacity to do the assembly? What were all the complaints of binary code programmers that did not accept to use Assembly? John Von Neumann changed his mind about the Assembly and Fortran? [View Less]

Checklist for changing Python's grammar
by Chris Angelico June 11, 2015

June 11, 2015

As part of a bit of hacking on CPython, I'm looking at playing with the grammar. In the source tree, Grammar/Grammar, there's a note advising me to follow the steps in PEP 306, but PEP 306 says it's been moved to the dev guide. Should the source comment be changed to point to https://docs.python.org/devguide/grammar.html ? Or is there a better canonical location for the dev guide? ChrisA

Fix or remove XMLParser.doctype()
by Serhiy Storchaka June 8, 2015

June 8, 2015

There are issues with the doctype() method of XMLParser. 1. Using subclass of XMLParser emits a deprecation warning [1]. 2. There is behavior difference between Python and C implementations if implement doctype() [2]. This method was deprecated for long time, and the simplest solution is to completely remove it. The questions are: 1. Can doctype() be removed or there is significant risk to break someone's code? 2. If fix doctype() instead of removing it (in any case should be done in … [View More]
