End of the mystery "@README.txt Mercurial bug"
by Victor Stinner July 1, 2013

July 1, 2013

Hi, One month ago, unit tests were added to IDLE (cool!) with a file called @README.txt. The @ was used to see the name on top in a listing of the directory. Some developers began to get strange Mercurial errors like: "abort: data/Lib/idlelib/idle_test/(a)README.txt.i at 7573717b9e6f: no match" " 83941: empty or missing Lib/idlelib/idle_test/(a)README.txt " etc. Senthil reported the issue on python-committers mailing list: http://mail.python.org/pipermail/python-committers/2013-May/002565.… [View More]

Issue 4199: combining assignment with global & nonlocal
by A.M. Kuchling June 30, 2013

June 30, 2013

Issue 4199 begins with a self-explanatory comment: PEP 3104 says that the nonlocal and global statements should allow a shorthand. ("global x; x = 3" == "global x = 3") This patch implements that. Benjamin posted his patch on 2008-10-24. It got postponed to 3.2 because it was too late for 3.1, and then to 3.3 because 3.2 still fell under the language moratorium, and then was forgotten for 3.3. Georg Brandl and Jeremy Hylton raised some issues with the patch and with the … [View More]

PyArg_ParseTupe(): parse unsigned integer and check for overflow
by Victor Stinner June 29, 2013

June 29, 2013

Hi, I don't understand why the B, H, I, k formats of PyArg_ParseTupe() do not check for overflow, whereas formats for signed numbers do check for overflow. What is the useful of ignoring overflow? http://docs.python.org/3/c-api/arg.html I would to parse an integer in [0; UINT_MAX] to fix the zlib module on 64-bit system: http://bugs.python.org/issue18294 How should I implement that? Use "O" format and then use PyLong_Check(), PyLong_AsLong(), and check value <= UINT_MAX? Victor

backported Enum
by Ethan Furman June 29, 2013

June 29, 2013

So I have the stdlb 3.4 Enum backported for both earlier 3.x and back to 2.4 in the 2.x series. I would like to put this on PyPI, but the `enum` name is already taken. Would it be inappropriate to call it `stdlib.enum`? -- ~Ethan~

June 29, 2013

I want use coffeescript function syntax to write python lambda expression so I modified the Grammar file. ``` atom: ('(' [yield_expr|testlist_comp|vararglist] ')' | '[' [testlist_comp] ']' | '{' [dictorsetmaker] '}' | NAME | NUMBER | STRING+ | '...' | 'None' | 'True' | 'False') trailer: '(' [arglist] ')' | '[' subscriptlist ']' | '.' NAME | '->' text ``` but when I write ``` (x,y=1)->x+y ``` the parser doesn't go into vararglist. any help?

Reminder: an oft-forgotten rule about docstring formatting (PEP 257)
by Guido van Rossum June 28, 2013

June 28, 2013

PEP 257 says this on the formatting of multi-line docstrings: """ Multi-line docstrings consist of a summary line just like a one-line docstring, followed by a blank line, followed by a more elaborate description. The summary line may be used by automatic indexing tools; it is important that it fits on one line and is separated from the rest of the docstring by a blank line. [...] """ I still like this rule, but it is violated frequently, in the stdlib and elsewhere. I'd like to urge stdlib … [View More]
