March 31, 2021

Hunor Portik <portikhun(a)gmail.com> added the comment: Hello I would really appreciate and I think many of us if every time I havent have to remember everything. Im not a Sys admin, devops, or who has in his mind every low level step and just shakes out of his little finger... Why do I have to take care at the high level where I stand with using Python? I think mustn't. So yes, as just a little noticement would be really helpful for us to remember we should look forward if we want to … [View More]

[issue43676] Doctest ELLIPSIS explanation hard to follow when they're missing
by Tim Hatch March 31, 2021

March 31, 2021

New submission from Tim Hatch <tshatch(a)gmail.com>: The doctest docs try to explain directives like ELLIPSIS but those directives are absent from the rendered html. Where? Most of the code blocks in the Directives section, and https://docs.python.org/3/library/doctest.html#directives and the one introduced by "nice approach" subsequently are missing their directive comments. The docs today say they go with Python 3.9.2 generated by Sphinx 2.4.4. I haven't tried generating them … [View More]

[issue36384] ipaddress Should not reject IPv4 addresses with leading zeroes as ambiguously octal
by STINNER Victor March 30, 2021

March 30, 2021

STINNER Victor <vstinner(a)python.org> added the comment: > The patch should not have landed in 3.8. At a bare minimum the patch should have been postponed until documentation was updated. Since 3.8 the ipaddresss does not behave as documented. A similar security issue in NPM was published two days ago, CVE-2021-28918.

[issue19124] os.execv executes in background on Windows
by Eryk Sun March 30, 2021

March 30, 2021

Eryk Sun <eryksun(a)gmail.com> added the comment: > Even if that's just swapping the execv call for spawnv(_P_WAIT) > and then exiting, that's fine by me Maybe call SuspendThread() on other threads, at least the ones that can be enumerated with the threading module. > I don't see how its behaviour would change at all, unless we're going > well out of our way to override the CRT.

[issue19124] os.execv executes in background on Windows
by Steve Dower March 30, 2021

March 30, 2021

Steve Dower <steve.dower(a)python.org> added the comment: > emulating exec() is probably good enough for most cases, especially if code expects to work in Windows. I think good-enough emulation is fine, but we should update the docs to clarify that non-Unix platforms may create a subprocess with a new PID, and callers should avoid relying on POSIX semantics if they may run on non-compliant platforms. > If Python implements its own system() and spawnv[e]() functions, support for … [View More]
