[issue40011] Tkinter widget events are of type Tuple

[Hênio Tierra Sampaio]

Hênio Tierra Sampaio  added the comment:

Sorry for the similar messages. The second one was to remove the paragraph 
stating that it would be possible to circumvent the problem of the Listbox - it 
is not.

[issue40011] Tkinter widget events are of type Tuple

[Hênio Tierra Sampaio]

Hênio Tierra Sampaio  added the comment:

I'm maintainer for a project for the RaspberryPi, a GUI for OMXPlayer called 
TBOPlayer. This GUI was originally made for Python 2, but with Python 2 
deprecation, I decided to convert it to Python 3. After (supposedly) converting 
all of it I had a surprise to see that the events that worked in the original 
code with Python 2 didn't work anymore in Python 3 with errors like

File "/home/henio/Projetos/tboplayer/lib/tboplayer.py", line 1566, in 
select_track
sel = event.widget.curselection()
AttributeError: 'tuple' object has no attribute 'widget'


And upon investigation, I noticed all the widget events (originally of type 
tkinter.Event) were now of type Tuple. WTF. Ok, I tried to circumvent this by 
using the tuple "attributes", like, in the event

(('17685', '1', '??', '??', '??', '256', '59467466', '??', '212', '11', 
'??', '0', '??', '??', '.!listbox', '5', '1030', '344', '??'),)

I can access the x position of the cursor in relation to the widget by doing:

event[0][8]

Which I did. However, I obviously cannot use any of the Event methods, and this 
way I cannot get the current selection from a Listbox, for example, and trying 
to gives me the exact error mentioned above. This renders TBOPlayer useless as 
the user cannot even select a track for playing.

And unfortunately, I was unable to reproduce this issue with a minimum code, so 
I have no idea what's going on.

[issue36479] Exit threads when interpreter is finalizing rather than runtime.

[STINNER Victor]

STINNER Victor  added the comment:

I suggest to close this issue, I don't think that it can be implemented because 
of daemon threads.

--

> This behavior should instead be triggered by the thread's interpreter 
> finalizing rather than the runtime.

What is the motivation for that?

--

take_gil() cannot access interp->finalizing since interp memory is freed during 
Python finalization.

take_gil() can only rely on a global variable like _PyRuntime to check if a 
daemon thread must exit during the Python finalization.

I modified take_gil() recently to fix 2 or 3 different crashes caused by daemon 
threads during Python finalization. Extract of ceval.c:

/* Check if a Python thread must exit immediately, rather than taking the GIL
   if Py_Finalize() has been called.

   When this function is called by a daemon thread after Py_Finalize() has been
   called, the GIL does no longer exist.

   tstate must be non-NULL. */
static inline int
tstate_must_exit(PyThreadState *tstate)
{
/* bpo-39877: Access _PyRuntime directly rather than using
   tstate->interp->runtime to support calls from Python daemon threads.
   After Py_Finalize() has been called, tstate can be a dangling pointer:
   point to PyThreadState freed memory. */
_PyRuntimeState *runtime = &_PyRuntime;
PyThreadState *finalizing = _PyRuntimeState_GetFinalizing(runtime);
return (finalizing != NULL && finalizing != tstate);
}


And simplified take_gil():

static void
take_gil(PyThreadState *tstate)
{
if (tstate_must_exit(tstate)) {
/* bpo-39877: If Py_Finalize() has been called and tstate is not the
   thread which called Py_Finalize(), exit immediately the thread.

   This code path can be reached by a daemon thread after Py_Finalize()
   completes. In this case, tstate is a dangling pointer: points to
   PyThreadState freed memory. */
PyThread_exit_thread();
}

(... logic to acquire the GIL ...)

if (must_exit) {
/* bpo-36475: If Py_Finalize() has been called and tstate is not
   the thread which called Py_Finalize(), exit immediately the
   thread.

   This code path can be reached by a daemon thread which was waiting
   in take_gil() while the main thread called
   wait_for_thread_shutdown() from Py_Finalize(). */
drop_gil(ceval, ceval2, tstate);
PyThread_exit_thread();
}
}

to gives me the exact error mentioned above. This renders TBOPlayer useless as 
the user cannot even select a track for playing.

I could circumvent this specific problem by keeping track of the previous 
clicked position over the Listbox and do a simple math calculation to get the 
current list item, but that's is very annoying, and not the right way to do it, 
meaning it would make the code more complex than it should be, and making 
maintaing more difficult.

And unfortunately, I was unable to reproduce this issue with a minimum code, so 
I have no idea what's going on.

[issue40010] Inefficient sigal handling in multithreaded applications

[STINNER Victor]

New submission from STINNER Victor :

When a thread gets a signal, SIGNAL_PENDING_SIGNALS() sets signals_pending to 1 
and eval_breaker to 1. In this case, _PyEval_EvalFrameDefault() calls 
handle_signals(), but since it's not the main thread, it does nothing and 
signals_pending value remains 1. Moreover, eval_breaker value remains 1 which 
means that the following code will be called before executing *each* bytecode 
instruction.

if (_Py_atomic_load_relaxed(eval_breaker)) {
(...)
opcode = _Py_OPCODE(*next_instr);
if (opcode == SETUP_FINALLY || ...) {
...
}
if (_Py_atomic_load_relaxed(>signals_pending)) {
if (handle_signals(tstate) != 0) {
goto error;
}
}
if (_Py_atomic_load_relaxed(>pending.calls_to_do)) {
...
}

if (_Py_atomic_load_relaxed(>gil_drop_request)) {
...
}
if (tstate->async_exc != NULL) {
...
}
}

This is inefficient.

I'm working on a PR modifying SIGNAL_PENDING_SIGNALS() to not set eval_breaker 
to 1 if the current thread is not the main thread.

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

I will try to investigate that but it think this is because without 
OBJECT_MODE=64 the value of decimal.MAX_PREC is much lower (42500
instead 99) so whatever is happening downstream with the higher 
does not happen with the lower one.

I will update If I found something useful on what is going on.

Perhaps sysconfig needs an overhaul to be able to handle _PYTHON_PROJECT_BASE 
properly? I see so many values in there that are taken from the running 
interpreter (sys.prefix, for example) that ought to come from the 
cross-compilation target. Wouldn't surprise me if the host's CFLAGS are leaking 
through and adding those extra includes.

[issue22699] Module source files not found when cross-compiling

[Steve Dower]

Steve Dower  added the comment:

Trimmed a bit from setup.py here, but I think this is the cause:

def build_extensions(self):
self.srcdir = sysconfig.get_config_var('srcdir')
self.srcdir = os.path.abspath(self.srcdir)

[SNIP]

# Fix up the autodetected modules, prefixing all the source files
# with Modules/.
moddirlist = [os.path.join(self.srcdir, 'Modules')]

In my build, I've set PYTHON_FOR_BUILD=python3.8, and the contents of 
moddirlist is '/usr/lib/python3.8/config-3.8-x86_64-linux-gnu/Modules'. So it's 
picking the wrong source directory.

I replaced the second line of the function above with:
self.srcdir = os.path.dirname(os.path.abspath(__file__))

Which made things a little better (I can launch my build now), but all the 
-I/usr/* options need to be replaced as well or there are no dynamically loaded 
modules.

[issue22699] cross-compilation of Python3.4

[Steve Dower]

Steve Dower  added the comment:

I'm now hitting this too, on nearly all the compiled modules in the stdlib. One 
example:

building '_codecs_jp' extension
x86_64-my-linux-gcc -m64 -march=core2 -mtune=core2 -msse3 -mfpmath=sse 
--sysroot=/opt/my-generic/0.0.1-dev/sysroots/core2-64-my-linux -fPIC 
-Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g 
-fstack-protector-strong -Wformat -Werror=format-security -g -fwrapv -O2 
-std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter 
-Wno-missing-field-initializers -Werror=implicit-function-declaration 
-I../Include/internal -I. -IObjects -IInclude -IPython 
-I/usr/include/x86_64-linux-gnu -I/usr/local/include -I/usr/include/python3.8 
-c cjkcodecs/_codecs_jp.c -o build/temp.linux-x86_64-3.8/cjkcodecs/_codecs_jp.o
x86_64-my-linux-gcc: error: cjkcodecs/_codecs_jp.c: No such file or directory
x86_64-my-linux-gcc: fatal error: no input files
compilation terminated.

I think the working directory is incorrect at some stage - note that the first 
two -I would make sense from Modules, but the next three do not.

[issue38865] Can Py_Finalize() be called if the current interpreter is not the main interpreter?

[STINNER Victor]

STINNER Victor  added the comment:

This issue became a blocker issue while working on bpo-39984, when I tried to 
move pending calls from _PyRuntimeState to PyInterpreterState.

I wrote PR 19063 to deny calling Py_FinalizeEx() from a subinterpreter.


Eric:
> On the other hand, if the "main" interpreter isn't special after runtime init 
> is done (i.e. a subinterpreter is effectively indistinguishable by nature) 
> then it certainly would not matter which one finalizes (or is active during

> unnecessary.

Well. Maybe we will be able to reach this point later, but right now, there are 
concrete implementation issues. The main interpreter remains special. Only the 
main interpreter is allowed to call fork(), spawn daemon threads, handle 
signals, etc.

If we manage to make subinterpreters less special, we can change 
Py_FinalizeEx() again later.


I asked:
> Is Python supposed to magically destroy the 3 interpreters?

Currently, Py_FinalizeEx() fails with a fatal error if there are remaining 
subinterpreters:
---
Fatal Python error: PyInterpreterState_Delete: remaining subinterpreters
Python runtime state: finalizing (tstate=0xfaa1c0)

Abandon (core dumped)
---

IMHO it's a good behavior.

if we want, we can modify Py_FinalizeEx() to magically end subinterpters later. 
The opposite may be more annoying for embedders.

[issue39917] new_compiler() called 2nd time causes error

[Todd Levi]

Todd Levi  added the comment:

In looking through the setup.py file for uvloop, I see that they purposely do 
not call super().initialize_options() or super().finalize_options() in their 
code if they've already been called once.

I think that is why their code is revealing this problem - the 2nd command to 
be run is inheriting the self.compiler value from the first command since 
build_ext.initialize_options() isn't being called to (re)set self.compiler to 
be None.

I'm not sure if there's a "rule" that says each command must call 
initialize_options() to "sanitize" the object or not but that does explain why 
the 2nd command is seeing a CCompiler object() for self.compiler on the 2nd 
time through.

[issue28686] py.exe ignored PATH when using python3 shebang

[Riccardo Polignieri]

Riccardo Polignieri  added the comment:

Three years later, this problem seems on the way to fix itself 
(https://xkcd.com/1822/).

Versioned shebangs (and versioned "/env" shebangs) used to be a more prominent 
issue when you needed a way to tell Python 2 / Python 3 scripts apart. With the 
sunset of Python 2.7-3.3 almost completed, now we have a reasonably homogeneous 
block of inter-compatible Pythons.
True, py.exe won't cope very well with versioned shebangs, but this seems to 
become less and less annoying by the day.

As for the other problem from issue 39785, ie Python 2 still being selected as 
"default" in deference to some arcane Linux convention that we have been 
dragging for ten years (even on Windows!)... it would be nice to finally have 
*that* fixed. 
But then again, having Python 2 installed on your Windows box is becoming 
increasingly rare. Most users are likely never hitting this weirdness any more. 



In the meantime, now we have yet another way of installing Python on Windows... 
versioned executables from the Store! With no py.exe! So, who knows, maybe 
py.exe is the past, versioned executable are the future...

To sum up, while I would certainly add a note to the docs, to clarify that 
py.exe does not support versioned "/env" shebangs, IMO today the work needed to 
specify a behaviour for all possible cases, possibly even extending/modifying 
Linux conventions, is just too much to be worth the effort.

[issue39980] importlib.resources.path() may return incorrect path when using custom loader

[Jason R. Coombs]

Jason R. Coombs  added the comment:

How's that for service ;)

Glad to hear it worked. I'm going to close this as won't fix (as it was 
reported against 3.7 and 3.8 and changing it for them would be 
backward-incompatible, even if more correct). Please report back if that 
outcome is unsatisfactory.

[issue40007] An attempt to make asyncio.transport.writelines (selector) use Scatter I/O

[tzickel]

New submission from tzickel :

I have a code that tries to be smart and prepare data to be chunked efficiently 
before sending, so I was happy to read about:

https://docs.python.org/3/library/asyncio-protocol.html#asyncio.WriteTransport.writelines

Only to see that it simply does:

self.write(b''.join(lines))

So I've attempted to write an version that uses sendmsg (scatter I/O) instead 
(will be attached in PR).

What I've learnt is:
1. It's hard to benchmark (If someone has an good example on checking if it's 
worth it, feel free to add such).
2. sendmsg has an OS limit on how many items can be done in one call. If the 
user does not call writer.drain() it might have too many items in the buffer, 
in that case I concat them (might be an expensive operation ? but that should 
not be th enormal case).
3. socket.socket.sendmsg can accept any bytes like iterable, but os.writev can 
only accept sequences, is that a bug ?
4. This is for the selector stream socket for now.

[issue40005] Getting different result in python 2.7 and 3.7.

[Tim Peters]

Tim Peters  added the comment:

u1 is a global _only_ in a process that runs `function()`, which declares u1 
global and assigns it a value.  You have no sane expectation that a worker 
process (none of which run `function()`) will know anything about it.

Are you sure you're running 2.7 and 3.7 on the same machine?  It's impossible 
that this code ever "worked" under Windows, but it might under Linux-y systems, 
which use `fork()` to create worker processes.

The traceback you showed was obviously run under Windows.  Under Python 2.7.11 
on Windows, I get the same kind of error:

NameError: global name 'u1' is not defined

This is the code:

from multiprocessing import Pool
import traceback

class Utils:
def __init__(self):
   self.count = 10

def function():
global u1
u1 = Utils()
l1 = range(3)
process_pool = Pool(1)
try:
process_pool.map(add, l1, 1)
process_pool.close()
process_pool.join()
except Exception as e:
process_pool.terminate()
process_pool.join()
print(traceback.format_exc())
print(e)

def add(num):
 total = num + u1.count
 print(total)

if __name__ == "__main__":
function()

[issue40006] enum: Add documentation for _create_pseudo_member_ and composite members

[Ram Rachum]

New submission from Ram Rachum :

Looking at the enum source code, there's a method `_create_pseudo_member_` 
that's used in a bunch of places. Its docstring says "Create a composite member 
iff value contains only members", which would have been useful if I had any 
idea what "composite member" meant.

It would be good if the documentation for the enum module would include more 
information about these two concepts.

[issue21199] [2.7] Python on 64-bit Windows uses signed 32-bit type for read length

[STINNER Victor]

STINNER Victor  added the comment:

Python 3 doesn't have this issue. Python 2 no longer accepts bugfixes. I close 
the issue.

Note: there was a similar issue specific to macOS: bpo-24658 and PR 9938 
(closed since Python 2 moved to end of life).

[issue37127] Handling pending calls during runtime finalization may cause problems.

[STINNER Victor]

STINNER Victor  added the comment:

trip_signal() has another problem. If pending->finishing is non-zero, 
_PyEval_AddPendingCall() uses the C API whereas the current thread may not hold 
the GIL. That's forbidden by the C API.

The more I think about it, the more I think that pending->finishing is fragile 
and should be removed.

I understood that pending->finishing was added to workaround crashes during 
Python finalization. I fixed multiple crashes related to daemon threads during 
Python finalization in bpo-39877. Maybe the bugs that I fixed were the ones 
which pending->finishing was supposed to work around.

[issue37127] Handling pending calls during runtime finalization may cause problems.

[STINNER Victor]

STINNER Victor  added the comment:

> pending->finishing was addd in bpo-33608 by the change: commit 
> 842a2f07f2f08a935ef470bfdaeef40f87490cfc

Since this change, Py_AddPendingCall() now requires the thread to have a Python 
thread state: it is used if pending->finishing is non-zero.

The function documentation says:

"This function doesn’t need a current thread state to run, and it doesn’t need 
the global interpreter lock."

https://docs.python.org/dev/c-api/init.html#c.Py_AddPendingCall

The current implementation seems to contradict the documentation.

We may update the documentation to replace "doesn't need" with "requires" (a 
Python thread state).

Or the implementation can use PyGILState_Ensure() and PyGILState_Release() to 
create a temporary Python thread state if the thread doesn't have one.

Removing pending->finishing would only partially fix the issue. With PR 19061, 
tstate is required to access "ceval" structure.

trip_signal() called by the C signal handler has a similar issue: it only 
requires non-NULL tstate if pending->finishing is non-zero.
