[issue40424] AIX: parallel build and ld WARNINGS

[Michael Felt]

Michael Felt  added the comment:

specifically, makexp_aix - from 1998-1999 - did not consider parallelization.

make -j2 is sufficient to create the following issue - that frequently leads to 
a failed compile/build.

./Modules/makexp_aix Modules/python.exp . libpython3.9d.a;  gcc -pthread 
-Wl,-bE:Modules/python.exp -lld -o python Programs/python.o libpython3.9d.a

./Modules/makexp_aix Modules/python.exp . libpython3.9d.a;  gcc -pthread

collect2: error: ld returned 8 exit status
Makefile:598: recipe for target 'python' failed
make: *** [python] Error 1
program finished with exit code 2

Explanation: makexp_aix is running in parallel - and writing to python.exp in 
parallel.

The patch/PR "tames" this - and, hopefully, multiple "fails" per day, of the 
AIX bots will cease.

p.s. needed in 3.8, 3.9 and the new master (3.10)

[issue40948] Better identify Windows installer as installer only, not runner

[Terry J. Reedy]

New submission from Terry J. Reedy :

Some beginners on Windows think that python-3.8.3-amd64.exe, for instance, is 
for running python-3.8.3, leading to repeated and now tiresome questions on 
python-list and probably elsewhere.  The latest example is "repair modify 
uninstall" with the core complaint that "after downloading and trying to launch 
it keeps saying repair modify uninstall".  (Actually, 'modify' comes first.)

In response, Grant Edwards suggested adding run instructions to the initial 
screen and asked a "Is the file name not clear that it's an installer?"

For the naive, the answer, as is traditional, is 'no'. How about adding 'setup' 
or 'install', as I have seen occasionally.
  python-3.8.3-amd64-setup.exe

The initial screen is different according to whether an installed binary is 
absent or present.  For the latter, add something like

Python 3.8.3 {n} bit is installed for {who}.
To run it, {directions}
To change it, click one of the buttons below.

An optional add-on would be a button to open the doc page on using python on 
Windows.

(I an not suggesting a button to actually run python.exe from the installer.  
Users should really learn how to start it properly according to platform and 
python-specific conventions and their particular needs.)

Does the final screen after installation say anything about running the new 
install?  (I cannot remember.)

Ned: I don't think that this issue afficts Mac newbies.  Perhaps python-xyz.pkg 
is more clearly not for running.  But something you might watch for.

I guess we could just remove this, as soon as the old parser is out. We were 
only using this to differentiate between the two parsers, when we were testing 
enabling/disabling the old one. I could get a PR ready to be merged after 
GH-20768 is there.

I would personally would like to keep the easter egg, but I assume is better to

[issue40746] test_gdb failing on Raspbian on 3.9, regression from 3.8

[STINNER Victor]

STINNER Victor  added the comment:

Some data from a recent build:
https://buildbot.python.org/all/#/builders/645/builds/480

That's 32-bit ARM, armv7l ABI with GCC 8.3 and GDB 8.2.

Python is built with -Og optimization level. In my experience, gdb fails to 
read debug symbols when Python is optimized at -Og level. Last time I asked a 
gdb developer, he told me that he always use -O0, so do I.

[issue40939] Remove the old parser

[STINNER Victor]

STINNER Victor  added the comment:

I did'nt ask to remove the easter egg. I'm just asking to avoid the "new" name. 
In my experience, each time that a "new" thing happens, later we have to use 
"new extended", "new_v2" or worse name :-)

Oh, if the name changes, please change it in 3.9 as well.


Look at this amazing names of the 5 flavors of functions parsing a string:

PyParser_ParseString()
PyParser_ParseStringFlags()
PyParser_ParseStringFlagsFilename()
PyParser_ParseStringFlagsFilenameEx() <= public!
PyParser_ParseStringObject()

Same for parsing a file:

PyParser_ParseFile()
PyParser_ParseFileFlags()
PyParser_ParseFileFlagsEx() <= public!
PyParser_ParseFileObject()

Or PyRun functions:

PyRun_String()
PyRun_AnyFile()
PyRun_AnyFileEx() <= public!
PyRun_AnyFileFlags()
PyRun_SimpleString()
PyRun_SimpleFile()
PyRun_SimpleFileEx() <= public!
PyRun_InteractiveOne()
PyRun_InteractiveLoop()
PyRun_File()
PyRun_FileEx() <= public!
PyRun_FileFlags()

ceval.c:

PyEval_EvalCode()
PyEval_EvalCodeEx() <= public!
_PyEval_EvalCodeWithName()
_PyEval_EvalCode()

I cannot count the number of "Ex" functions that we have :-)

Py_Finalize() -> :Py_FinalizeEx() <= public!
PyErr_Print() -> PyErr_PrintEx() <= public!
PySys_SetArgv() -> PySys_SetArgvEx() <= public!
PyErr_WarnEx() <= public!

_PyBytes_FormatEx()
_PyDict_MergeEx()
_Py_DecodeLocaleEx(), _Py_EncodeLocaleEx()
struct PyMemAllocatorEx
_Py_DecodeUTF8Ex(), _Py_EncodeUTF8Ex()
etc.

[issue40746] test_gdb failing on 32-bit armv7l when built with GCC -Og (fail on Raspbian on 3.9, regression from 3.8)

[STINNER Victor]

STINNER Victor  added the comment:

> Marking release blocker as this isn't present in 3.8 or earlier, we've got a 
> regression here.

FYI we have issue with test_gdb on Fedora for at least 5 years. Most issues 
come from -Og optimization level of test_gdb.

Recently, I modified test_gdb to skip tests when we detect that gdb fails to 
read debug symbols, which happens often when using -Og: bpo-40019.

commit 7bf069b6110278102c8f4719975a5eb5a5af25f9

bpo-40019: Skip test_gdb if Python was optimized (GH-19081)

test_gdb now skips tests if it detects that gdb failed to read debug
information because the Python binary is optimized.

[issue40941] Merge generator.gi_running and frame executing flag into single frame state

[Mark Shannon]

Mark Shannon  added the comment:

This change combines the explicit state in `PyFrameObject.f_excuting` and 
`PyGenObject.gi_running`, and the implicit state in `PyFrameObject.f_stacktop 
== NULL` and `PyFrameObject.f_last == -1` into a single enum field in 
`PyFrameObject`.

Since we no longer need to test `PyFrameObject.f_stacktop == NULL` , The 
`f_stacktop` pointer can be replaced with a `f_stackdepth` integer, which make 
for simpler code when iterating over the stack and avoids the potential hazard 
of NULL pointers.

There are  three benefits to these changes:

1. The code is more robust and, IMO, easier to understand, as all state is now 
explicit.
2. It carries additional information about the state of the frame. Information 
about whether a frame exiting by `return` or by `raise` is available.
3. A modest reduction in size of frame and generator objects.

[issue34401] Make test_gdb work on HP-UX

[STINNER Victor]

STINNER Victor  added the comment:

Thanks Michael Osipov for the fix! It's already merged into the master branch 
and will be merged into 3.8 and 3.9 branches as soon as the CI tests pass on 
the two backport PRs.

I don't think that it's worth it to backport the fix to 3.7: this branch is 
close to move to security fixes only. I prefer to reduce any risk of regression.

[issue40275] test.support has way too many imports

[STINNER Victor]

STINNER Victor  added the comment:

I'm no longer sure that it's worth it to create support.process_helper. I only 
see these functions which would be untroversial for process_helper:

* wait_process()
* reap_children()
* args_from_interpreter_flags()
* optim_args_from_interpreter_flags()

PythonSymlink might be moved to support.script_helper instead.

For now, I suggest to leave all these functions in support/__init__.py.

[issue40275] test.support has way too many imports

[STINNER Victor]

STINNER Victor  added the comment:

I propose to start updating tests to use directly support.import_helper and 
support.os_helper. Hai: do you want to work on that? Maybe start by focusing on 
import_helper (but if you modify a test, check for also symbols imported from 
os_helper).

When you modify tests, I suggest to remove "from .import_helper import ..." and 
"from .os_helper import ..." in support/__init__.py and then run tests, to 
ensure that you updated all imports of the modified tests.

Try to not create giant PRs modifying 100+ files. For example, limit a PR to 20 
test files.

When PR 20812 will be merged and import_helper and os_helper will no longer be 
imported  by support, "import test.support" done after "import unittest"  will 
only import 17 modules which is way better than the situation in April!

[issue40275] test.support has way too many imports

[hai shi]

hai shi  added the comment:

I propose to start updating tests to use directly support.import_helper and 
support.os_helper. Hai: do you want to work on that? Maybe start by focusing on 
import_helper (but if you modify a test, check for also symbols imported from 
os_helper).

> of course, I will do it.

Try to not create giant PRs modifying 100+ files. For example, limit a PR to 20 
test files.

> forgive me again. I will create some PRs of appropriate size.

[issue40948] Better identify Windows installer as installer only, not runner

[Steve Dower]

Steve Dower  added the comment:

The current "using" doc page is way too in-depth, but I'm actually okay with 
the idea of having a "Did you mean to launch Python? Press 'Start' and type 
'Python' to find it" message on the Modify page of the installer.

Perhaps the people hitting this problem would read the final page of the 
installer, but I suspect they're just like everyone else and don't read 
instructions until just-in-time. So if they're reaching the Modify page, that's 
the place to put them.

[issue40945] TKinter.Tk.geometry(Tk.winfo_geometry()) should be idempotent

[E. Paine]

E. Paine  added the comment:

This is interesting as it works fine on Windows but does the behaviour you 
describe on Linux. I presume the difference is due to how Tcl/Tk handles the 
title-bar, in which case this isn't really a tkinter issue and there isn't much 
that can be done (from a tkinter perspective anyway).

When tested (on Linux), however, calling tk.geometry() returned a different 
value to tk.winfo_geometry(). Calling tk.geometry(tk.geometry()) did not change 
the window position and everything worked as expected (weird!).

I am not sure, though, if this behaviour should be changed. Looking at the Tk 
man page (https://www.tcl.tk/man/tcl8.6/TkCmd/wm.htm#M42), it says:
"Note that this is related to winfo geometry, but not the same. That [...] 
always reflects Tk's current understanding of the actual size and location of 
window, whereas wm geometry allows [...] querying of the window manager's 
understanding of the size and location of the window. This can vary 
significantly, for example to reflect the addition of decorative elements to 
window such as title bars, and window managers are not required to precisely 
follow the requests made through this command."

[issue40940] How to update pip permanently for new venv?

[Ned Deily]

Ned Deily  added the comment:

Thanks for the report.  I have to agree that the behavior is a little bit 
counterintuitive but I believe everything is working as designed and 
documented.  It all comes down to the fact that the ensurepip module is only 
concerned with the version of pip bundled with the python release; ensurepip 
deliberately does not check PyPI for a newer version of pip.  As documented, 
venv calls ensurepip after creating a new venv so the pip that is installed 
there is the one released with ensurepip. To get the latest version of pip, you 
would need to run (in the activated venv):

python3 -m pip install --upgrade pip

just as you needed to do to upgrade the system-wide instance of python3 to the 
latest pip.

https://docs.python.org/3/library/venv.html#creating-virtual-environments
  "Unless the --without-pip option is given, ensurepip will be invoked
   to bootstrap pip into the virtual environment."

https://docs.python.org/3/library/venv.html#creating-virtual-environments
  "Note: This module does not access the internet [...]"

[issue40855] statistics.stdev ignore xbar argument

[Raymond Hettinger]

Raymond Hettinger  added the comment:

> do you have any comment on my previous answer?

I see what you're trying to do but think that interpretation is surprising
and is at odds with the existing and intended uses of the *xbar* argument.  

The goals were to allow the mean to be precomputed (common case) or to be 
recentered (uncommon).  Neither case should have the effect of changing the 
divisor.  

We can't break existing code that assumes that stdev(data) is equal to 
stdev(data, xbar=mean(data)).

>>> data = [1, 2]
>>> stdev(data)
0.7071067811865476
>>> stdev(data, xbar=mean(data))
0.7071067811865476
