Python misbehavior
Friends, Please forgive me if this is not the proper forum for dealing with an issue of mine, but I am at a loss in finding a fix for a python problem in the program ClipGrab. The program allows one to download videos or audios from YouTube and other media sites. My limited understanding of the process suggests that python facilitates the transfer of data from YouTube to ClipGrab. As of recently, I am unable to use the ClipGrab program and the issue at fault has something to do with python. In an "about" screen within ClipGrab my (now) incapable python script reads: youtube-dlp: (C:\Program Files (x86)\ClipGrab\python\python.exe: can't find '_main_' module in " ) Python: C:/Program Files (x86)/ClipGrab/python/python.exe (Python 3.8.9) Since this problem began I downloaded ClipGrab on to another desktop computer and it runs perfectly without a problem. The script on the "about" page does not indicate anything about "can't find -main- module" etc. Is there any advice you can offer to overcome this and recover my downloading connections to YouTube? Or, if this is the wrong group to handle such issues, could you please pass my message on to a better choice?

No, but I use pyperclip. It's cross platform. Maybe it doesn't have this
problem, though I don't know for sure.

I’m not sure this is the shortest method, but you could set up two python scripts to do the same thing and convert them to c using cython.

It is part of visual studio C++.
Once you have that installed there are bat files that setup environment in the
terminal.
Then you can use cl, nmake etc

RE: Windows installer from python source code without access to source code
I downloaded VS community 2022 and I know how to access the developer command
prompt. I'm using the one called x64 Native Tools Command Prompt for VS 2022
I ran a command to compile my python code that was converted to c with the

It is part of visual studio C++.
Once you have that installed there are bat files that setup environment in the
terminal.
Then you can use cl, nmake etc

can use a setup.py program to run the compile and link and create a windows

Cython can compile a script to C source code for a module or executable
(--embed). The source can be compiled and linked normally.
For example, the following builds a "hello.exe" executable based on a
"hello.py" script.

Hello, World!
I extracted the complete embeddable distribution of Python 3.11 into the
"embed" directory. You can reduce the size of the installation, if needed, by
minimizing the zipped standard library and removing pyd extensions and DLLs
that your application doesn't use.
The generated "hello.c" is large and not particularly easy to read, but here

Re: Windows installer from python source code without access to source code
I am writing an app but I’m not sure I’ll sell it yet. I have it in a private GitHub location and GitHub prompts me for a license. I don’t really understand licenses so I just picked Apache 2.0.

[issue46180] Button clicked failed when mouse hover tooltip and tooltip destroyed
Jim Wygralak added the comment: DATA: Just chiming in to report that I'm seeing this issue with the following freshly installed: Python 3.10.4 tkinter 8.6.12 PySimpleGUI 4.57.0 OS is Windows 10 As others have report it is related to the cursor entering the tool tip box before clicking the button. OBSERVATIONS: I've noticed that the tool tip always seems to appear up and to the right of the cursor. If I approach the button by moving the cursor down & left, the tool tip appears when the cursor enters the button, then as I continue to move the cursor to the center of the button I'm moving AWAY FROM the tool tip, and the issue doesn't appear. However, if I approach the button by moving the cursor up and to the right, the tool tip appears as the cursor enters the button, and it overlaps the button. As I continue to move the cursor to the center of the button, it enters the tool tip box and triggers this fault. The only 100% effective workaround appears to be not using tooltips. That is a loss of function, and not an acceptable long term solution. -- nosy: +jim.wygralak ___ Python tracker <https://bugs.python.org/issue46180> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue45819] Avoid releasing the GIL in nonblocking socket operations
New submission from Jim Crist-Harif : In https://bugs.python.org/issue7946 an issue with how the current GIL interacts with mixing IO and CPU bound work. Quoting this issue: > when an I/O bound thread executes an I/O call, > it always releases the GIL. Since the GIL is released, a CPU bound > thread is now free to acquire the GIL and run. However, if the I/O > call completes immediately (which is common), the I/O bound thread > immediately stalls upon return from the system call. To get the GIL > back, it now has to go through the timeout process to force the > CPU-bound thread to release the GIL again. This issue can come up in any application where IO and CPU bound work are mixed (we've found it to be a cause of performance issues in https://dask.org for example). Fixing the general problem is tricky and likely requires changes to the GIL's internals, but in the specific case of mixing asyncio running in one thread and CPU work happening in background threads, there may be a simpler fix - don't release the GIL if we don't have to. Asyncio relies on nonblocking socket operations, which by definition shouldn't block. As such, releasing the GIL shouldn't be needed for many operations (`send`, `recv`, ...) on `socket.socket` objects provided they're in nonblocking mode (as suggested in https://bugs.python.org/issue7946#msg99477). Likewise, dropping the GIL can be avoided when calling `select` on `selectors.BaseSelector` objects with a timeout of 0 (making it a non-blocking call). I've made a patch (https://github.com/jcrist/cpython/tree/keep-gil-for-fast-syscalls) with these two changes, and run a benchmark (attached) to evaluate the effect of background threads with/without the patch. The benchmark starts an asyncio server in one process, and a number of clients in a separate process. A number of background threads that just spin are started in the server process (configurable by the `-t` flag, defaults to 0), then the server is loaded to measure the RPS. Here are the results: ``` # Main branch $ python bench.py -c1 -t0 Benchmark: clients = 1, msg-size = 100, background-threads = 0 16324.2 RPS $ python bench.py -c1 -t1 Benchmark: clients = 1, msg-size = 100, background-threads = 1 Spinner spun 1.52e+07 cycles/second 97.6 RPS $ python bench.py -c2 -t0 Benchmark: clients = 2, msg-size = 100, background-threads = 0 31308.0 RPS $ python bench.py -c2 -t1 Benchmark: clients = 2, msg-size = 100, background-threads = 1 Spinner spun 1.52e+07 cycles/second 96.2 RPS $ python bench.py -c10 -t0 Benchmark: clients = 10, msg-size = 100, background-threads = 0 47169.6 RPS $ python bench.py -c10 -t1 Benchmark: clients = 10, msg-size = 100, background-threads = 1 Spinner spun 1.54e+07 cycles/second 95.4 RPS # With this patch $ ./python bench.py -c1 -t0 Benchmark: clients = 1, msg-size = 100, background-threads = 0 18201.8 RPS $ ./python bench.py -c1 -t1 Benchmark: clients = 1, msg-size = 100, background-threads = 1 Spinner spun 9.03e+06 cycles/second 194.6 RPS $ ./python bench.py -c2 -t0 Benchmark: clients = 2, msg-size = 100, background-threads = 0 34151.8 RPS $ ./python bench.py -c2 -t1 Benchmark: clients = 2, msg-size = 100, background-threads = 1 Spinner spun 8.72e+06 cycles/second 729.6 RPS $ ./python bench.py -c10 -t0 Benchmark: clients = 10, msg-size = 100, background-threads = 0 53666.6 RPS $ ./python bench.py -c10 -t1 Benchmark: clients = 10, msg-size = 100, background-threads = 1 Spinner spun 5e+06 cycles/second 21838.2 RPS ``` A few comments on the results: - On the main branch, any GIL contention sharply decreases the number of RPS an asyncio server can handle, regardless of the number of clients. This makes sense - any socket operation will release the GIL, and the server thread will have to wait to reacquire it (up to the switch interval), rinse and repeat. So if every request requires 1 recv and 1 send, a server with background GIL contention is stuck at a max of `1 / (2 * switchinterval)` or 200 RPS with default configuration. This effectively prioritizes the background thread over the IO thread, since the IO thread releases the GIL very frequently and the background thread never does. - With the patch, we still see a performance degradation, but the degradation is less severe and improves with the number of clients. This is because with these changes the asyncio thread only releases the GIL when doing a blocking poll for new IO events (or when the switch interval is hit). With low load (1 client), the IO thread becomes idle more frequently and releases the GIL. Under higher load though the event loop frequently still has work to do at the end of a cycle and issues a `selector.select` call with a 0 timeout (nonblocking), avoiding releasing the GIL at all during that loop (note the nonlinear effect of adding more clients). Since the IO thread still releases the GIL sometimes, the background thread still holds the GIL a larger percen
[issue45693] `loop.create_server` with port=0 uses different ports for ipv4 & ipv6
Jim Crist-Harif added the comment:
> Is tornado the only example or you are aware of other libraries with such
> behavior?
A quick survey of other language network stacks didn't turn anything up, *But*
I also didn't find any implementations (other than asyncio & tornado) that bind
multiple sockets with a single api call (as `create_server` does).
I think part of the issue here is that dual IPV6 & IPV4 support is
intentionally disabled in asyncio (and tornado), so two sockets are needed (one
to support each interface). Other TCP implementations (e.g. both go and rust)
don't disable this, so one listener == one socket. This makes comparing API
designs across stacks harder - with e.g. Go it's straightforward to listen on a
random port on IPV4 & IPV6 with a single TCPListener, since both can be handled
by a single socket. Since this is disabled (by default) in asyncio we end up
using 2 sockets and run into the issue described above.
Also note that this issue will trigger for any address that resolves to
multiple interfaces (not just `host=""`). For example, on osx `localhost` will
resolve to `::1` and `127.0.0.1` by default, meaning that the following fairly
straightforward asyncio code has a bug in it:
```python
# Start a server on localhost with a random port
server = await loop.create_server(
EchoServerProtocol,
host="localhost",
port=0
)
# Retrieve and log the port
port = server.sockets[0].getsockname()[1]
print(f"listening at tcp://localhost:{port}")
```
As written, this looks correct enough, but on systems where localhost resolves
to multiple interfaces this will accidentally listen on multiple ports (instead
of one). This can be fixed with some additional logic external to asyncio, but
it makes for a much less straightforward asyncio example.

Jim Crist-Harif added the comment: > I'm not aware of an OS API call that binds both IPv4 and IPv6 to the same > random port. Sure, but `loop.create_server` is already higher-level than a single OS API call. By default `create_server` will already bind multiple sockets if `host=""`, `host=None`, or if `host` is a list. I'm arguing that the current behavior with `port=0` in these situations is unexpected. Other libraries (like tornado) have come to the same conclusion, and have implemented logic to handle this that seems to work well in practice (though can fail, as you've pointed out). Is there a use case where the current behavior (binding to multiple random ports) is desired? -- ___ Python tracker <https://bugs.python.org/issue45693> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue45693] `loop.create_server` with port=0 uses different ports for ipv4 & ipv6
Jim Crist-Harif added the comment: > Is there an OS interface to ensure the same port on both stacks? I don't think this is needed? Right now the code processes as: - Expand host + port + family + flags into a list of one or more tuples of socket options (https://github.com/python/cpython/blob/401272e6e660445d6556d5cd4db88ed4267a50b3/Lib/asyncio/base_events.py#L1432-L1436) - Iterate through this list, creating a new socket for each option tuple, and bind to the corresponding host + port (https://github.com/python/cpython/blob/401272e6e660445d6556d5cd4db88ed4267a50b3/Lib/asyncio/base_events.py#L1441-L1464) In this case, each call to `socket.bind` gets a 0 port, thus binding to a new random open port number each time. What I'm asking for is that if the user passes in `port=0`, then the port is extracted in the first call to `socket.bind` when looping and used for all subsequent `socket.bind` calls in the loop. This way we only ever choose a single random open port rather than 1 for each interface. FWIW, this is also what tornado does when `port=0` is provided. -- ___ Python tracker <https://bugs.python.org/issue45693> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24275] lookdict_* give up too soon
Jim Jewett added the comment: Based on Hristo's timing, it appears to be a clear win. A near-wash for truly string-only dicts that shouldn't be effected; a near-wash for looking up non-(exact-)strings, and a nearly 40% speedup for the target case of looking up but not inserting a non-string or string subclass, then looking up strings thereafter. Additional comments: Barring objections, I will promote from patch review to commit review when I've had a chance to look more closely. I don't have commit privs, but I think some of the others following this issue do. The test looks pretty good enough -- good enough that I wonder if I'm missing something on the parts that seem odd. It would be great if you either cleaned them up or commented to explain why: Why is the first key vx1, which seems, if anything, like a variable? Why not k1 or string_key? Why is the first key built up as vx='x'; vx += '1' instead of just k1="x1"? Using a str subclass in the test is a great idea, and you've created a truly minimal one. It would probably be good to *also* test with a non-string, like 3 or 42.0. I can't imagine this affecting things (unless you missed an eager lookdict demotion somewhere), but it would be good to have that path documented against regression. This seems like a test that could probably be rolled into a bigger testfile for the actual commit. I don't have the name of such an appropriate file at hand right now, but will try to find it on a deeper review. -- ___ Python tracker <https://bugs.python.org/issue24275> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue36675] Doctest directives and comments missing from code samples
Jim DeLaHunt added the comment: My goodness, things get complex sometimes. If we cannot make Sphinx preserve doctest directives and comments, perhaps we should go back to the historical bug discussion to look at workarounds which we considered earlier. For instance, maybe we should modify the text surrounding the examples to explain that doctests directives should appear there, but that our tool chain currently removes them. At the moment, I see doctest directives in the doctest source code at: https://github.com/python/cpython/blob/master/Doc/library/doctest.rst#directives which do not appear in the corresponding HTML output at: https://docs.python.org/3/library/doctest.html#directives How about rewording the text before each of those examples? Or maybe finding some way to show those examples as literal text which Sphinx won't modify, even if it is not formatted like Python code examples? By the way, the discussion of this same problem back in 2011-2012 is at #12947 . At that time, we applied a "monkey patch" to the Sphinx code. I haven't read the discussion closely enough to figure out if such a patch would help now. -- ___ Python tracker <https://bugs.python.org/issue36675> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Jim Jewett added the comment: Unicode probably won't make the correction, because of backwards compatibility. I do support the sentence suggested in Thorsten's most recent reply.

[issue41212] Emoji Unicode failing in standard release of Python 3.8.3 / tkinter 8.6.8
Jim Jewett added the comment: @Ben Griffin -- Unicode has defined astral characters for a while, but they were explicitly intended for rare characters, with any living languages intended for the basic plane. It is only the most recent releases of unicode that have broken the "most people won't need this" expectation, so it wasn't unreasonable for languages targeting memory-constrained devices to make astral support at best a compile-time operation. I've seen a draft for an upcoming spec update of an old but still-supported language (extended Gerber, for photoplotting machines) that "handles" this simply by clarifying that their unicode support is limited to characters < 65K. Given that their use of unicode is essentially limited to comments, and there is plenty of hardware that can't be updated ... this is may well be correct. Python itself does the right thing, and tcl can't do the right thing anyhow without font support ... so this may be fixed in less time than it would take to replace Tk/Tcl.

I don't know pandas that well. My only contact with it is when a module
I am using depends on it. So does the dataframe look correct?
The error complains of line 1, column 1. Just looking at the dataframe
it looks like Date is on a different line from the rest of the headers
or is that just the result of being printed in the terminal?
On the yfinance github issues page there were a few people reporting
this error. A couple of people reported a work around using try/except.
It worked for some people and not others. It didn't work for me.
I'd appreciate any advice you could give.
My guess is that pandas is not the source of the problem. The error occurs
when simplejson tries to parse an empty string:
import simplejson
simplejson.loads("")
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python3/dist-packages/simplejson/__init__.py", line 488, in

simplejson.scanner.JSONDecodeError: Expecting value: line 1 column 1 (char

This probably means that yahoo returns an empty string instead of the
expected JSON. If the error occurs only sporadically and you can identify
the downloading code in the API source you can try and replace (pseudo-code)
json_data = download_from_yahoo()
df = dataframe_from_json(json_data)
with
while True:
json_data = download_from_yahoo()
if json_data: break
time.sleep(1) # wait a moment, then retry download
df = dataframe_from_json(json_data)
Thanks, I have it working now by wrapping a for loop in a try/except.

I don't know pandas that well. My only contact with it is when a module
I am using depends on it. So does the dataframe look correct?
The error complains of line 1, column 1. Just looking at the dataframe
it looks like Date is on a different line from the rest of the headers
or is that just the result of being printed in the terminal?
On the yfinance github issues page there were a few people reporting
this error. A couple of people reported a work around using try/except.
It worked for some people and not others. It didn't work for me.
I'd appreciate any advice you could give.
It's complaining about the JSON data that it's getting. What does that
data look like when it complains?
It might be that there's some kind of limit to how often you can get the
data and it's trying to tell you that, but you're not expecting anything
back except the data.
You could add some temporary code at line 897 of
"/home/jfb/EVs/env36/lib/python3.6/site-packages/requests/models.py" to
save the data to a file just before the decoding. Remember to make a
backup copy of any source file that you modify!
I don't think it is a limit problem. It happened the first time I ran
the script after a week of not using it. I am only geting info on 33
stocks and I know that people use this module to get info on 100's of
stocks.
Anyway I was wrong about the try/except not solving the problem. I made
a mistake in the try/except and when I corrected it, like a dummy, I
never saved the change before running it again.
I will use your suggestions to see if I can figure out the root cause of
the problem. as before today it ran for months with no errors. Sorry for
taking up the lists time with my mistake and thanks for your help.
Regards, Jim

Does this dataframe look correct?
linux mint 19.3, python 3.6
I wrote a program to download stock info from yahoo using yfinance. I
have been running it unchanged for the past 3 months, today it gave an
error. When looping through a list of stocks the error is random, never
the same position in the list.
I wrote the following little test script to show the error:
import yfinance as yf
import pandas as pd
day = '2020-06-25'
aapl = yf.Ticker('AAPL')
hist = aapl.history(start=day)
print(hist)
close = hist.loc[day]['Close']

[issue40852] Dictionary created with dict.fromkeys have issues (all explained in the file)
New submission from Jim Fasarakis-Hilliard :
This isn't an issue, `value` (that is, `{}` here) is shared among all keys.
Since you've added a mutable value, when you mutate it this change is seen for
all keys holding the value.
This is documented in dict.fromkeys

[issue40846] Misleading line in documentation
Jim Fasarakis-Hilliard added the comment: A simple substitution of 'types' with 'kind' should do it. This aligns with the terminology [1] used in the glossary.

Re: Trouble with version 3.8
I had been using python 3.6 on two computers with windows 7 and windows 10. We bought a windows 10 machine and I installed python 3.8 on it. Many of my python apps failed with an error similar to this: File "C:\Python38\lib\os.py", line 818, in fsdecode filename = fspath(filename) # Does type-checking of `filename`.TypeError: expected str, bytes or os.PathLike object, not list I looked online and could not find any solutions to my problem. So, I uninstalled v3.8 and installed v3.6. Version 3.6 worked. Any advice on how to fix version 3.8 would be appreciated. -- https://mail.python.org/mailman/listinfo/python-list
[issue40838] inspect.getsourcefile documentation doesn't mention it can return None
Jim Fasarakis-Hilliard added the comment: For a more comprehensive list, we currently have for `get*` functions in `inspect`: `inspect.getdoc`: Returns `None` if the documentation string isn't present, either directly on the object or through it mro. This *isn't* documented. `inspect.getfile`: Explicitly seems to handle None cases. After peeking a bit in the `PyCode_*` interface, it doesn't seem to be possible to assign `None` to the `co_filename` so the returning the `object.co_filename` in the function appears to not be able to return `None`. `inspect.getmodule`: Returns None in a number of cases. This *isn't* documented. `inspect.getsourcefile`: Returns None if the filename indicates an extension module or when none of the ifs are matched. This *isn't* documented. Some (getmodulename, getcomments) do document this. Agreed that the rest of the cases where `None`s might be returned should be documented. -- nosy: +Jim Fasarakis-Hilliard ___ Python tracker <https://bugs.python.org/issue40838> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17005] Add a topological sort algorithm
Jim Fasarakis-Hilliard added the comment: Another option, `graphlib`[1], does exist on PyPI but is not maintained and currently read-only by the author. Other flavors[2][3] of the same name also don't seem to have much adoption so they shouldn't confuse if a name like `graphlib` was chosen.

[issue17005] Add a topological sort algorithm
Jim Fasarakis-Hilliard added the comment: The downside I see with any graph prefixed names is the fact that it implies a larger collection of graph operations. Add that to the fact that people might be more tempted to propose many graph related algorithms/utilities to a module with the same name. A more localized name solves that. -- ___ Python tracker <https://bugs.python.org/issue17005> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17005] Add a topological sort algorithm
Jim Fasarakis-Hilliard added the comment: It does seem out of place in functools, intensified by it's odd interjection among the other functools objects. Considering heapq and bisect exist as standalone modules, the idea that topological sorting could go in its own module wouldn't be without precedent. -- nosy: +Jim Fasarakis-Hilliard ___ Python tracker <https://bugs.python.org/issue17005> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
