Python 2.7 EOL date
by Collin Anderson 03 Sep '18

03 Sep '18

Hi All, Sorry if this has been mentioned before, but I noticed the Python 2.7 EOL date was recently set to Jan 1st, 2020. My understanding was Python releases get 5 years of support from their initial release, and Python 2.7 was extended an additional 5 years. Python 2.7 was originally released on 2010-07-03, and with an original EOL of 2015-07-03. Extended 5 years, shouldn't the EOL be 2020-07-03? Also, this statement is a little unclear to me: > Specifically, 2.7 will receive bugfix support until January 1, 2020. All 2.7 development work will cease in 2020. This statement makes it sound like bugfixes end on Jan 1st, but seems to leave open the possibility that security fixes could continue through the year. Thanks! Collin

AIX and python tests
by Michael 02 Sep '18

02 Sep '18

As I have time, I'll dig into these. I have a couple of PR already 'out there', which I hope someone will be looking at when/as he/she/they have time. My time will also be intermittent. My next test - and I hope not too difficult - would be the test_utf8. The test: FAIL: test_cmd_line (test.test_utf8_mode.UTF8ModeTests) fails - and I am wondering if it is as simple as AIX default mode is ISO8559-1 and the test looks to be comparing UTF8 with the locale_default. If that is the case, obviously this test will never succeed - asis. Am I understanding the test properly. If yes, then I'll see what I can come up with for a patch to the test for AIX. If no, I'll need some hand holding to help me understand the test A bigger challenge, and I think a major issue with many of the test failures is test_ssl. Here I already know I'll need so assistance. I am quite lost. I know AIX at an expert level, but I do not know python (especially python internals, macros, etc..) and after about 3 levels I am lost. I also find it hard to get 'artifacts' from the tests to know what is expected. Looking forward to assistance from various people - in understanding the tests, and probably better python coding criticism. Michael

UTF-8 Mode now also enabled by the POSIX locale
by Victor Stinner 02 Sep '18

02 Sep '18

Hi, While working on test_utf8_mode on AIX (bpo-34347) and HP-UX (bpo-34403), I noticed that FreeBSD doesn't work properly with the POSIX locale (bpo-34527). I also noticed that my implementation of my PEP 540 "UTF-8 Mode" doesn't respect the PEP: the UTF-8 Mode should be enabled by the POSIX locale, not only by the C locale. I just modified Python 3.7 and master (future 3.8) to enable UTF-8 Mode if the LC_CTYPE locale is "POSIX": https://bugs.python.org/issue34527 I also fixed FreeBSD to support the "POSIX" locale as well (3.6, 3.7 and master branches). Note: The C locale coercion (PEP 538) is only enabled if the LC_CTYPE locale is "C". To finish my list of recent Unicode issues, I'm also working on bpo-34523: select the Python filesystem encoding before Py_Initialize(). This change will allow embedders to force an encoding instead of letting Python choose one for them. Victor

make patchcheck and git path
by Michael 01 Sep '18

01 Sep '18

I am trying to be a 'good scout' and run "make patchcheck" more regularly. However, I generally am not successful because I build and test in separate directories. There is access to git! just no ready reference in the build area. So, not calling it a bug - but if someone else also experiences this, and feels capable of makeing it more flexible - you will get thanks from me, in any case! Michael

A Subtle Bug in Class Initializations
by Eddie Elizondo 30 Aug '18

30 Aug '18

Background: Through the implementation of an alternate runtime I've been poking around some of the class initialization routines and I found out that there was a subtle bug with PyType_Ready and the header initializer PyVarObject_HEAD_INIT. Looking through the codebase, I couldn't really find any pattern of when the type should be defined within PyVarObject_HEAD_INIT. Sometimes it was initialized to NULL (or 0) and PyType_Type (let's ignore Py_True and Py_False from now). From PyType_Ready it turns out that setting the value PyType_Type is never actually needed outside of PyType_Type and PyBaseObject type. This is clear from the code: if (Py_TYPE(type) == NULL && base != NULL) Py_TYPE(type) = Py_TYPE(base);  Given that any PyTypeObject's base is of type PyType_Type, setting PyVarObject_HEAD_INIT(&PyType_Ready) is superfluous. Therefore, setting all static PyTypeObjects to their ob_type to NULL should be a safe assumption to make. Uninitialized Types: A quick s/PyVarObject_HEAD_INIT(&PyType_Type/PyVarObject_HEAD_INIT(NULL/ shows that some objects do need to have their ob_type set from the outset, violating the previous assumption. After writing a quick script, I found that out of the ~300 PyVarObject_HEAD_INIT present in CPython, only these 14 types segfaulted: PyByteArrayIter_Type PyBytesIter_Type PyDictIterKey_Type PyDictIterValue_Type PyDictIterItem_Type PyClassMethod_Type PyAsyncGen_Type PyListIter_Type PyListRevIter_Type PyODictIter_Type PyLongRangeIter_Type PySetIter_Type PyTupleIter_Type PyUnicodeIter_Type Bug: It turns out that these PyTypeObjects are never initialized through PyType_Ready. However, they are used as fully initialized types. It is by pure chance that the work without having to call the initializer on them. This though is undefined behavior. This not only might result in a weird future bug which is hard to chase down but also, it affects other runtimes as this behavior depends on implementation details of CPython. This is a pervasive pattern that should be removed from the codebase and ideally extensions should follow as well. Solution: Here are my proposed solutions in order from less controversial to most controversial. Note that all of them I already tried in a local branch and are working: 1) Initialize all uninitialized types. Example: https://github.com/eduardo-elizondo/cpython/commit/bc53db3cf4e5a6923b0b1afa… 2) Move all PyVarObject_HEAD_INIT to NULL except PyType_Type, PyBaseObject_Type and the booleans. 3) Special case the initialization of PyType_Type and PyBaseObject_Type within PyType_Ready to now make all calls to PyVarObject_HEAD_INIT use NULL. To enable this a small change within PyType_Ready is needed to initialize PyType_Type PyBaseObject: if (base == NULL) { Py_TYPE(&PyType_Type) = &PyType_Type; Py_TYPE(type) = &PyType_Type; } Also, the booleans have to be fully initialized without calling PyVarObject_HEAD_INIT. I propose: struct _longobject _Py_FalseStruct = { PyObject_HEAD_INIT(&PyBool_Type), 0, { 0 } }; This will clean-up the entire codebase of this anti-pattern. Example: https://github.com/eduardo-elizondo/cpython/commit/542fd79e4279c64c077c127b… 4) Modify PyVarObject_HEAD_INIT to ignore the input and initialize to NULL and 0. In order to prevent this antipattern within extension code as well, we should make PyVarObject_HEAD_INIT ignore the inputs and just set the value to NULL. #define PyVarObject_HEAD_INIT(type, size) \ { PyObject_HEAD_INIT(NULL) 0 }, This will prevent external code to have a semi-initialized type that is not initialized through PyType_Ready. 5) Finally, I would go even further and suggest making PyVarObject_HEAD_INIT argumentless. #define PyVarObject_HEAD_INIT \ { PyObject_HEAD_INIT(NULL) 0 }, However, this breaks backward compatibility. That being said, this will make extension maintainers aware of this antipattern. Example: https://github.com/eduardo-elizondo/cpython/commit/3869e53843008ff096764f4a… Thoughts?

Review of Pull Request #2078
by Pierre Quentel 28 Aug '18

28 Aug '18

Hi, A few months ago I have submitted the Pull Request #2078 named "bpo-30576 : Add HTTP compression support to http.server". After a couple of iterations, discussions on the PR page ( https://github.com/python/cpython/pull/2078) and on the bug tracker ( https://bugs.python.org/issue30576), it seems to me that there are no objection to adding this feature (the Github page even has recent messages favorable to its inclusion) and that the implementation is not a complete mess ;-) It has been in the "waiting core review" state for many months now. As indicated on the contributing page ( https://github.com/python/cpython/blob/master/.github/CONTRIBUTING.rst) I send this message to python-dev to see if one of the core developers could take a look at the Pull Request. Thanks for your time, Pierre

AIX, test_ssl in particular, but also AIX failed tests in general - getting to the 'STABLE' side
by Michael 27 Aug '18

27 Aug '18

Dear all, Last week I experimented with test_ssl. My expectation was that test failures was caused by the openssl.base provided by IBM for AIX not having a default certificate file (CApath). However, that is not the case. The tests that fail are similar to: self.assertRaisesRegex(ssl.SSLError, "PEM lib") I started out by testing with something as: if not AIX: with self.assertRaisesRegex(ssl.SSLError, "PEM lib"): ctx.load_cert_chain(BADCERT) else: with self.assertRaises(ssl.SSLError): ctx.load_cert_chain(BADCERT) This is after an analysis where I saw that calls too SSL were returning an non-success status (!= 1) while ERR_peek_last_error() regularly returned 0. Hence, the frequent 'AssertionError: "PEM lib" does not match "unknown error ...' with "unknown error" the string Python provides. While above might remove the 'fail messages' it did not satisfy me. So, I downloaded openssl (1.0.2p) and compiled - with no optimization! And now, even from Python3.6 I see: test_ssl passed in 1 min 23 sec == Tests result: SUCCESS == 1 test OK. In short, the failures of test_ssl may be ignored - as far as raising an exception goes. a) I am running a bot for Python, and once the argument "-with-openssl=/opt/aixtools" is added my bot will stop showing these errors. I mention this so that it is clear why they suddenly disappear on my bot (but not elsewhere). Also to alert Python-Dev that the AIX platform, regarding ssl.py, _ssl.c and test_ssl.py functions 'stable' but is not as friendly when it comes to saying why WHEN (my guess) a heavily optimized (I am thinking -O3 to -O5) library is used. b) With this feedback - MAYBE - the team from IBM might review the way they package openssl and make sure the messages are visible via ERR_peek_last_error() et al. Ideally, IBM will notice and work on it without prompting. One can dream :) c) In the meantime - I am curious to know what this 'proof' means to Python-Dev. I have a simple goal - work through the tests that AIX has been failing historically and figure out why they fail and fix the tests. To that end I have submitted several PR's - starting back In January, then nothing as noone ever seemed to notice, and the last weeks several additional ones. Victor has been kind enough to say he will look at the tests as he has time (and back from vacation). But we are all, or most, working on our time. My goal, rephrased, is to see AIX in the 'stable' column so that when a test fails it is because there is a regression that needs addressing - either in the test or in the proposed code change. So I would be grateful if others were also looking. I am not trying to re-invent the wheel and will not be surprised if my 'test fix' is not done in the 'Python' way. I'll learn over time - but this calls for instructive (and critical) comments. "bij voorbaat dank" aka Thanks in Advance. So, hoping this helps - I'll continue as I can. Time and resources are limited. And, I am very curious re: point c) above. Great Days! everyone, Michael
