[RELEASED] Python 3.4.9 and Python 3.5.6 are now available
by Larry Hastings 07 Aug '18

07 Aug '18

On behalf of the Python development community, I'm happy to announce the availability of Python 3.4.9 and Python 3.5.6. 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. You can find Python 3.4.9 here: https://www.python.org/downloads/release/python-349/ And you can find Python 3.5.6 here: https://www.python.org/downloads/release/python-356/ We now return you to your pitched debate already in progress, //arry/

Re: [Python-Dev] Error message for wrong number of arguments
by Jeroen Demeyer 04 Aug '18

04 Aug '18

On 2018-07-30 17:28, Nick Coghlan wrote: > I would, and I think it would make sense for the PEP to cite improving > consistency (and reducing code duplication?) in that regard as an > advantage of the PEP. I'm not sure to which PEP you are referring (PEP 580 or a new PEP?). After thinking a bit about the issue of error messages, I realized that PEP 580 would make this easier to fix (to be clear: there are ways to fix it without PEP 580, I'm just saying that PEP 580 makes it easier). There are two related reasons for this: * The existing code which calls the actual underlying C function doesn't have access to the Python-level function object. So it can't know whether it's a function (where self doesn't count) or a method (where self counts). * Armin Rigo suggested to use a new flag to indicate this difference: that would certainly work for Argument Clinic (just have Argument Clinic add that flag). For methods defined without Argument Clinic, we cannot require such a new flag though. We could still add the flag at runtime, but it's far from clear if we can freely change the flags inside a PyMethodDef at runtime (at least, no existing code that I know does that). PEP 580 solves the first issue by having the function object available and it solves the second issue by not relying on PyMethodDef at all for calling functions/methods. The second issue especially can be generalized as: PEP 580 makes the implementation of functions/methods much less rigid, making it easier to change the implementation. So maybe this can be seen as yet another advantage of PEP 580. Jeroen.

New _Py_InitializeFromConfig() function (PEP 432)
by Victor Stinner 04 Aug '18

04 Aug '18

Hi, I finished my work on the _PyCoreConfig structure: it's a C structure in Include/pystate.h which has many fields used to configure Python initialization. In Python 3.6 and older, these parameters were scatted around the code, and it was hard to get an exhaustive list of it. This work is linked to the Nick Coghlan's PEP 432 "Restructuring the CPython startup sequence": https://www.python.org/dev/peps/pep-0432/ Right now, the new API is still private. Nick Coghlan splitted the initialization in two parts: "core" and "main". I'm not sure that this split is needed. We should see what to do, but it would be nice to make the _PyCoreConfig API public! IMHO it's way better than the old way to configuration Python initialization. -- It is now possible to only use _PyCoreConfig to initialize Python: it overrides old ways to configure Python like environment variables (ex: PYTHONPATH), global configuration variables (ex: Py_BytesWarningFlag) and C functions (ex: Py_SetProgramName()). I added tests to test_embed on the different ways to configure Python initialization: * environment variables (ex: PYTHONPATH) * global configuration variables (ex: Py_BytesWarningFlag) and C functions (ex: Py_SetProgramName()) * _PyCoreConfig I found and fixed many issues when writing these tests :-) Reading the current configuration, _PyCoreConfig_Read(), no longer changes the configuration. Now the code to read the configuration and the code to apply the configuration is properly separated. The work is not fully complete, there are a few remaining corner cases and some parameters (ex: Py_FrozenFlag) which cannot be set by _PyCoreConfig yet. My latest issue used to work on this API: https://bugs.python.org/issue34170 I had to refactor a lot of code to implement all of that. -- The problem is that Python 3.7 got the half-baked implementation, and it caused issues: * Calling Py_Main() after Py_Initialize() fails with a fatal error on Python 3.7.0 https://bugs.python.org/issue34008 * PYTHONOPTIMIZE environment variable is ignored by Py_Initialize() https://bugs.python.org/issue34247 I fixed the first issue, I'm now working on the second one to see how it can be fixed. Other option would be to backport the code from master to the 3.7 branch, since the code in master has a way better design. But it requires to backport a lot of changes. I'm not sure yet what is the best option. Victor

Finding Guido's replacement
by Chris Angelico 03 Aug '18

03 Aug '18

Guido's term as Benevolent Dictator For Life has been a long one, but in the wake of his resignation, we have an opportunity to correct some fundamental flaws in the system. Among them: * Guido lacks patience, as evidenced by the brevity of his acceptance posts. See https://mail.python.org/pipermail/python-dev/2017-December/151038.html and https://mail.python.org/pipermail/python-dev/2011-November/114545.html and particularly https://mail.python.org/pipermail/python-dev/2016-May/144646.html where Guido specifically cites his own lack of patience. * Lately, all Guido's actions have been to benefit his employer, not the Common Pythonista. We have proof of this from reliable reporting sources such as Twitter and social media. * Finally, "For Life" is far too long. We need to change our rulers periodically. I propose a new way to appoint a project head. All candidates shall be flown to an island owned by the Python Secret Underground (which emphatically does NOT exist, but an island that would be owned by it if it did), whereupon they parachute down, search for guns, and proceed to fight each other until only one is left alive. The survivor shall be treated to a chicken dinner and proclaimed Patient, Understanding, Benevolent Governor, a title which shall be retained for one fortnight, after which we repeat the exercise. If this plan meets with broad approval, I shall write up PEP 3401, in honour of the prior art in PEP 401. ChrisA

Re: [Python-Dev] Error message for wrong number of arguments
by Jeroen Demeyer 03 Aug '18

03 Aug '18

Actually, I just realized that it's not really possible to fix the error messages for built-in methods. The problem is that Argument Clinic does not know whether a function or method is being handled. For example, there is no indication at all that this is a method (note that the name "list.insert" might refer to a function "insert" inside a module called "list" or a method "insert" or a class "list"): /*[clinic input] list.insert index: Py_ssize_t object: object / Insert object before index. [clinic start generated code]*/

That would be quite hard. The error message is generated by the underlying function. At that point, the information of how it was called (as bound method or not) is already gone. Jeroen.

test_zlib.py suggestion
by Michael 02 Aug '18

02 Aug '18

I have a build_bot running (yeah me!), and was surprised to see test_zlib fail on AIX. There is not an issue with test_zlib, but I do have a suggestion. I was getting an error with test_flushes(). On python2-2.7.15 the test passes and in python3-3.8 (and earlier I expect) the test fails. The difference is the addition of the two modes 'Z_PARTIAL_FLUSH' and 'Z_BLOCK' sync_opt = ['Z_NO_FLUSH', 'Z_SYNC_FLUSH', 'Z_FULL_FLUSH', 'Z_PARTIAL_FLUSH', 'Z_BLOCK'] On default AIX installs zlib is, sadly, still at version 1.2.3 and Z_BLOCK was 'improved' in version 1.2.5. And it fails on Z_BLOCK. My suggestion is to enhance the test_library_version() so that it verifies that the minor (or smaller?) number is at least '5' When I static link python with zlib-1.2.11 then the test_zlib passes all sub-tests. Again, not a python bug - but a suggestion for improving what is tested. I can open an issue, and with a bit of assistance/interest from others I'll even do a PR. Michael

I haven't been following the process discussions, so I'm just asking the question. For example, given that you are already looking at PEP 580, would it be possible for you to handle PEP 580 as official BDFL-Delegate (even if there is no BDFL)? > So it's worthless that waiting PEP accepted before start PoC. First of all, it's too early for a proof-of-concept of native C calling. We first have to design the theory before we can start implementing anything. But even if we could start to write a proof of concept, I would really prefer doing that on top of PEP 580. There are two reasons for this: 1. If PEP 580 is rejected, I very much doubt that the native C calling protocol will be accepted. 2. I would be good to use PEP 580 as a framework for the implementation. Otherwise we have to implement it twice: once before PEP 580 with the proof-of-concept and then again after PEP 580 with the "real" implementation. Jeroen.

spwd and AIX
by Michael 01 Aug '18

01 Aug '18

a) I am looking at getting spwd integrated from AIX b) only the parameter sp_pwdp is my concern - as AIX really does not want to reveal the encrypted password. Rather, AIX will say '!' (meaning there is, or should be a shadow password, or '*' - no user password). Would this horribly break things if only '!' was returned, rather than the shadow password? It does not look terribly hard - but how do you deal with defaults such as 0 or -1 for the numeric values? Regards, Michael
