[issue20927] Different behaviour on Posix and Windows when using subprocess.Popen(..., cwd=path)
by Jovik Feb. 4, 2017

Feb. 4, 2017

New submission from Jovik: This works on Linux as expected: import subprocess proc = subprocess.Popen(["./app"], stdout=subprocess.PIPE, cwd="workspace") but on Windows I get: FileNotFoundError: [WinError 2] The system cannot find the file specified To successfully execute it on Windows I need to set shell=True first: proc = subprocess.Popen(["app.exe"], stdout=subprocess.PIPE, cwd="workspace", shell=True) which is odd since by default it should use cwd when searching for binary: "If cwd is … [View More]

by anatoly techtonik Feb. 4, 2017

Feb. 4, 2017

New submission from anatoly techtonik <techtonik(a)gmail.com>: The reason I ask is this changeset - http://code.google.com/p/spyderlib/source/detail?spec=svne5d86b685619a470d5… - seems like without shell=True, subprocess.Popen is unable to find Mercurial executable in PATH. ---------- assignee: docs@python components: Documentation messages: 145664 nosy: docs@python, techtonik priority: normal severity: normal status: open title: subprocess: undocumented if shell=True is necessary to … [View More]

[issue29430] zipfile: invalid link
by Serhiy Storchaka Feb. 4, 2017

Feb. 4, 2017

Serhiy Storchaka added the comment: https://support.pkware.com/display/PKZIP/Application+Note+Archives contains links to old versions of APPNOTE (the last is 6.3.3). But the actual version was at least 6.3.4 (I have a local copy). All external links refer to http://www.pkware.com/documents/casestudies/APPNOTE.TXT. I think we should report a bug to PKWare. ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue29430> _______________________________________

[issue15451] PATH is not honored in subprocess.Popen in win32
by Eryk Sun Feb. 4, 2017

Feb. 4, 2017

Eryk Sun added the comment: > difference from the behaviour of Posix's execvpe() was deliberate POSIX doesn't define execvpe [1]. GNU glibc implemented it in 2009 [2]. On Windows, MSC has had execvpe and spawnvpe since at least 5.0 [3], and I think it arrived in 4.0 in 1986. Guido added os._execvpe in 1.2b4 [4] in 1995. I think it's the only implementation of execvpe that searches the passed environment. [1]: http://pubs.opengroup.org/onlinepubs/9699919799/functions/execvp.html [2]: … [View More]

Dear team, I found a bug when using round. it is using a number ending with .575 like: 2613.575 which when rounding it shows 2613.575 but when adding 0.0000000001 it goes well. I am attaching a example I on a test windows we use for python code. and I found when it is a 2713.575 it goes well too. I was trying with different number and remembert it went bad when it was a xxxxx.575 long number but 6 (xxxxxx.575) long went ok again when rounding. I thanks for the support. I am a 3 months … [View More]
