Addendum to PEP 530
by Serhiy Storchaka 04 Mar '19

04 Mar '19

PEP 530 introduced support for asynchronous comprehensions. Comprehensions are implemented as local functions. To make a function asynchronous you should to add "async" before "def", and after that you can use "async for", "async with" and "await" in a function. But you can to do this with comprehensions, since these functions are implicit. PEP 530 allows to make these function asynchronous by just using asynchronous syntax inside. "async with" can not be used in comprehensions, but using "async for" or "await" makes the comprehension asynchronous. What PEP 530 missed is that asynchronous comprehensions itself are asynchronous constructions which can be used only in asynchronous functions. Issue33346 [1] makes an asynchronous comprehension inside a comprehension making the outer comprehension asynchronous as well as using explicit "async for" or "await". See details on the issue. Yury, the author of PEP 530, likes this idea, and there is a ready implementation. But making the decision was deferred until a new government be stated. Now, after the Steering Council has been elected, can it make the decision? [1] https://bugs.python.org/issue33346

[RELEASED] Python 3.4.10rc1 and Python 3.5.7rc1 are now available
by Larry Hastings 04 Mar '19

04 Mar '19

On behalf of the Python development community, I'm chuffed to announce the availability of Python 3.4.10rc1 and Python 3.5.7rc1. Both Python 3.4 and 3.5 are in "security fixes only" mode. Both versions only accept security fixes, not conventional bug fixes, and both releases are source-only. The "final" releases on both these branches should be out in about two weeks. Of particular note: that release of Python 3.4, Python 3.4.10 final, will be the final release ever in the Python 3.4 series. After 3.4.10, the branch will be closed for good and I'll retire as Python 3.4 Release Manager. I'll still be the Python 3.5 Release Manager until 3.5 similarly concludes, approximately eighteen months from now. You can find Python 3.4.10rc1 here: https://www.python.org/downloads/release/python-3410rc1/ And you can find Python 3.5.7rc1 here: https://www.python.org/downloads/release/python-357rc1/ Best wishes, //arry/

Another update for PEP 394 -- The "python" Command on Unix-Like Systems
by Petr Viktorin 01 Mar '19

01 Mar '19

PEP 394 says: > This recommendation will be periodically reviewed over the next few > years, and updated when the core development team judges it > appropriate. As a point of reference, regular maintenance releases > for the Python 2.7 series will continue until at least 2020. I think it's time for another review. I'm especially worried about the implication of these: - If the `python` command is installed, it should invoke the same version of Python as the `python2` command - scripts that are deliberately written to be source compatible with both Python 2.x and 3.x [...] may continue to use `python` on their shebang line. So, to support scripts that adhere to the recommendation, Python 2 needs to be installed :( Please see this PR for details and a suggested change: https://github.com/python/peps/pull/893

before I open an issue re: posix.stat and/or os.stat
by Michael 01 Mar '19

01 Mar '19

My focus is AIX - and I believe I found a bug in AIX include files in 64-bit mode. I'll take that up with IBM and AIX support. However, this issue might also be valid in Python3. The following is from Centos, not AIX Python 2.7.5 (default, Jul 13 2018, 13:06:57) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.maxsize 9223372036854775807 >>> import posix >>> posix.stat("/tmp/xxx") posix.stat_result(st_mode=33188, st_ino=33925869, st_dev=64768L, st_nlink=1, st_uid=0, st_gid=0, st_size=0, st_atime=1550742595, st_mtime=1550742595, st_ctime=1550742595) >>> st=posix.stat("/tmp/xxx") >>> dev=st.st_dev >>> min=posix.minor(dev) >>> maj=posix.major(dev) >>> min,max (0, <built-in function max>) >>> min 0 >>> max <built-in function max> >>> maj 253 >>> posix.minor(dev) 0 >>> posix.major(655536) 2560 >>> posix.major(65536) 256 >>> posix.major(256) 1 >>> import os >>> os.major(256) 1 >>> In AIX - 64-bit mode Python 3.8.0a1+ (heads/master:e7a4bb554e, Feb 20 2019, 18:40:08) [C] on aix7 Type "help", "copyright", "credits" or "license" for more information. >>> import sys,os,posix >>> sys.maxsize 9223372036854775807 >>> posix.major(256) 0 >>> posix.major(65536) 1 >>> posix.stat("/tmp/xxx") os.stat_result(st_mode=33188, st_ino=12, st_dev=-9223371993905102841, st_nlink=1, st_uid=202, st_gid=1954, st_size=0, st_atime=1550690105, st_mtime=1550690105, st_ctime=1550690105) AIX 32-bit: root@x066:[/data/prj/python/git/python3-3.8.0.66]./python Python 3.8.0a1+ (heads/master:e7a4bb554e, Feb 19 2019, 11:22:56) [C] on aix6 Type "help", "copyright", "credits" or "license" for more information. >>> import os,sys,posix >>> sys.maxsize 2147483647 >>> posix.major(65536) 1 >>> posix.stat("/tmp/xxx") os.stat_result(st_mode=33188, st_ino=149, st_dev=655367, st_nlink=1, st_uid=0, st_gid=0, st_size=0, st_atime=1550743517, st_mtime=1550743517, st_ctime=1550743517) To make it easier to view: buildbot@x064:[/home/buildbot]cat osstat.c #include <sys/types.h> #include <sys/stat.h> #include <sys/sysmacros.h> #include <stdio.h> main() { dev_t dev; char *path = "/tmp/xxx"; struct stat st; int minor,major; lstat(path,&st); printf("size: %d\n", sizeof(st.st_dev)); dev = st.st_dev; minor = minor(dev); major = major(dev); printf("%016lx %ld %ld\n",dev,dev, (unsigned) dev); printf("%d,%d\n",major,minor); } buildbot@x064:[/home/buildbot]OBJECT_MODE=32 cc osstat.c -o osstat-32 && ./osstat-32 size: 4 00000000000a0007 655367 655367 10,7 And here is the AIX behavior (and bug - major() macro!) buildbot@x064:[/home/buildbot]OBJECT_MODE=64 cc osstat.c -o osstat-64 && ./osstat-64 size: 8 8000000a00000007 -9223371993905102841 7 0,7 The same on AIX 6 (above is AIX7) - and also with gcc: root@x068:[/data/prj]gcc -maix64 osstat.c -o osstat-64 && ./osstat-64 size: 8 8000000a00000007 -9223371993905102841 42949672967 0,7 root@x068:[/data/prj]gcc -maix32 osstat.c -o osstat-32 && ./osstat-32 size: 4 00000000000a0007 655367 0 10,7 root@x068:[/data/prj] So, the AIX 'bug' with the macro major() has been around for ages - but ALSO setting the MSB of the st_dev. +++++ Now my question: Will this continue to be enough space - i.e., is the Dev size going to be enough? +2042 #ifdef MS_WINDOWS +2043 PyStructSequence_SET_ITEM(v, 2, PyLong_FromUnsignedLong(st->st_dev)); +2044 #else +2045 PyStructSequence_SET_ITEM(v, 2, _PyLong_FromDev(st->st_dev)); +2046 #endif +711 #define _PyLong_FromDev PyLong_FromLongLong It seems so - however, Is there something such as PyUnsignedLong and is that large enough for a "long long"? and if it exists, would that make the value positive (for the first test). posix.major and os.major will need to mask away the MSB and posix.makedev and os.makedev will need to add it back. OR - do I need to make the PyStat values "the same" in both 32-bit and 64-bit? Puzzled on what you think is the correct approach. Michael

The Python Steering Council is pleased to provide an update to the Python community about Steering Council activity and CPython development. We've created a GitHub repo for Steering Council updates and helpful documents: https://github.com/python/steering-council Here's the latest update written after our meeting on February 26th: https://github.com/python/steering-council/blob/master/updates/2019-02-26_s… (https://link.getmailspring.com/link/2AACF155-36B1-4D80-A2C1-A948561C45E4@ge…) We'll be posting updates after each steering council meeting which will be roughly twice a month.

[RELEASE] Python 3.8.0a1 is now available for testing
by Łukasz Langa 01 Mar '19

01 Mar '19

I packaged another release. Go get it here: https://www.python.org/downloads/release/python-380a2/ Python 3.8.0a2 is the second of four planned alpha releases of Python 3.8, the next feature release of Python. During the alpha phase, Python 3.8 remains under heavy development: additional features will be added and existing features may be modified or deleted. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next preview release, 3.8.0a3, is planned for 2019-03-25. This time around the stable buildbots were a bit less green than they should have. This early in the cycle, I didn't postpone the release and I didn't use the revert hammer. But soon enough, I will. Let's make sure future changes keep the buildbots happy. - Ł
