Cannot install python properly - python310.dll not found - no pip

[Jay Cadet | Studio JPC via Python-list]

Hi. I'm attempting to install and use stable diffusion. However, while 
installing python 3.10.6, I'm getting the error that the python 310.dll is not 
found. I've made sure the PATH option is enabled, but it makes no difference. 
I've also removed and reinstalled python multiple times.

Even though I get that error, the python still installs, but when I open the 
webui-user.bat file in the stable diffusion folder, it opens up the command 
center and says that there's no module named pip.

Please advise on how to fix this problem.

Thank you,

Jay Cadet

[issue46570] Windows support for OpenSSL 3.0

[Jay Lee]

New submission from Jay Lee :

Steps to reproduce:
1) Compile OpenSSL 3.0 on Windows.
2) use get_externals.bat to download Python external requirements on Windows.
3) Overwrite OpenSSL 1.1.1m in externals with your OpenSSL 3.0 build.

Expected behavior:
Python will build against OpenSSL 3.0

Actual behavior:
Build fails with missing DLLs.

Further information:
- For OpenSSL 3.0 builds, the first suffix for libcrypto and libssl is -3, not 
-1_1.
- For x86_64 builds, there's also an -x64 suffix to distinguish from x86 builds.

I have a openssl.props modified file at:
https://github.com/GAM-team/actions-hello-world/blob/master/openssl.props

which I've overwritten the existing:
https://github.com/python/cpython/blob/main/PCbuild/openssl.props#L13

file with and then succesfully compiled against OpenSSL 3.0. However I'm not 
certain if or where the logic should exist to detect OpenSSL 3.0 DLLs instead 
of 1.1.

[issue33125] Windows 10 ARM64 platform support

[Jay Swanson]

Jay Swanson  added the comment:

I know this is closed, but is it possible that the ARM64EC support coming in 
Windows 11 that allows mixed native/emulated code is something that would help 
this along? That along with the sunsetting of 32-bit systems.

[issue44583] Failure to build on OSF1.

[Jay Krell]

Jay Krell  added the comment:

I have a machine up and running that I would like to run this on.
Perhaps that is vastly inadequate.
Nothing is free, I realize.

And Solaris, agreed, would seem to merit "more" support, but zero==zero.

I will see if I can setup a buildbot and I am wondering being a core developer, 
if I have the time, ability (probably), approval, etc.

As long as Solaris is in an amd64 VM (not SPARC) I am interested in that as 
well. I have run it recently and it is vastly easier/faster than OSF1.

[issue44583] Failure to build on OSF1.

[Jay Krell]

Jay Krell  added the comment:

> "credible offer to maintain platform support for several years."

Probably. What does "support" mean?

Fix user-reported bugs? I expect very few/zero.

Run a buildbot? Maybe. Not sure it is worthwhile, depending on frequency.

Provide little autoconf/ifdef patches to keep it working? Sure.
 Hopefully there is some route for "degraded" or "missing" functionality on a 
platform by platform basis; the lack of monotonic time is kinda a problem in my 
PR.

Anyway I'll reread the PEP and email the group, which I tried to join, not sure 
it is working yet.

I will try to use it and keep my copy updated.
I have some python2 scripts I can try to update.

[issue39950] Add pathlib.Path.hardlink_to()

[Jay Chu]

Jay Chu  added the comment:

For me, and as you've pointed out, the current doc of `Path.link_to` is already 
wrong and misleading. Perhaps a fix of the doc should be made as a first step.

The doc uses the expression "Create a hard link pointing to a path named 
target." 
But comparing this to the doc of `Path.symlink_to`, which says "Make this path 
a symbolic link to target.", 
(and the doc of `os.link`, which says, "Create a hard link pointing to src 
named dst.",)
the current doc should actually be "Create a hard link at `target` pointing to 
this path." Sadly the argument name can't be changed here already.

And the doc of `Path.symlink_to` even have a helpful note: "Note: The order of 
arguments (link, target) is the reverse of os.symlink()’s." 
We could also add one for `Path.link_to`, too, like "Note: The order of 
arguments (link, target) is the consistent with os.link()’s.

Based on that foundation, we could finally continue to implement the correct 
"Path.hardlink_to". 

We can refer to how people retained `subprocess.call` while adding a newer , 
preferred `subprocess.run`, by noting people to prefer `Path.hardlink_to` as 
it's more consistent with the `pathlib` and OOP, along with telling them the 
obscurity of `Path.link_to` and why it's left here for backward capability.

[Jay Chu]

Jay Chu  added the comment:

Maybe we could have the correct `Path.hardlink` implemented before removing or 
even deprecating the confusing `Path.link_to`? It will only help even if we 
don't remove the latter in a hurry.

[issue41799] splunklib.client does not handle Unicode characters

[Jay Patel]

New submission from Jay Patel :

Using splunklib.client module to use Pythonic interface to the Splunk REST API. 
I am using the connect method of the module to connect and log in to a Splunk 
instance.

Code:
import splunklib.client as splunk_client
kwargs_config_flags = {
'host': "test_instance漢字",
'port': 8089,
'username': ,
'password': ,
'owner': None,
'app': None}
sc = splunk_client.connect(**kwargs_config_flags)

For python 3
Output:
''latin-1' codec can't encode characters in position 0-1: ordinal not in 
range(256)'

I tried to encode the host to utf-8, "test_instance漢字".encode("utf-8")
Output:
'a bytes-like object is required, not 'str''

For python 2
It is working as expected.
output: 'nodename nor servname provided, or not known'

Is there a way by which this can be handled at the module level?

[issue41157] email.message_from_string() is unable to find the headers for the .msg files

[Jay Patel]

New submission from Jay Patel :

I need to extract the email data from an MSG file on Python v2.7. But as Python 
v2.7 has been deprecated, I tried to replicate this scenario on Python v3.8 and 
faced the same issue.
I am trying to extract the message using the "Message" class of the 
"extract_msg" module. After extracting the text from the "Message" object, I am 
using email.message_from_string() method to separate the headers and the body 
(or payload). The same workflow can be observed in the "extract_mail.py" file.
The issue with the attached file, "msgfile_not_working_correctly.msg", is that 
the headers of this file begin with "Microsoft Mail Internet Headers Version 
2.0" which is interpreted as body and not as headers (as it is not in the 
standard email headers format like "To": "recei...@gmail.com").
According to this 
(https://support.microsoft.com/en-us/office/view-internet-message-headers-in-outlook-cd039382-dc6e-4264-ac74-c048563d212c)
 link the message headers in Outlook will begin with "Microsoft Mail Internet 
Headers Version 2.0" which is added by Outlook (mentioned in the "Interpreting 
email headers" section of the mentioned link). 
The email data can be observed in the "email_data.txt" file.

I have tried omitting the first line, when there are no headers and it works as 
per the expectation. Can this scenario be handled at the modular level (email 
module) or is there any other way to extract headers for the .msg files.

[issue41023] smtplib does not handle Unicode characters

[Jay Patel]

New submission from Jay Patel :

According to the user requirements, I need to send an email, which is provided 
as a raw email, i.e., the contents of email are provided in form of headers. To 
accomplish this I am using the methods provided in the "send_rawemail_demo.py" 
file (attached below).
The smtplib library works fine when providing only 'ascii' characters in the 
'raw_email' variable. But, when I provide any Unicode characters either in the 
Subject or Body of the email, then the sendmail method of the smtplib library 
fails with the following message:
UnicodeEncodeError 'ascii' codec can't encode characters in position 123-124: 
ordinal not in range(128)
I tried providing the mail_options=["SMTPUTF-8"] in the sendmail method (On 
line no. 72 in the send_rawemail_demo.py file), but then it fails (even for the 
'ascii' characters) with the exception as SMTPSenderRefused.
I have faced the same issue on Python 3.6. 
The sendmail method of the SMTP class encodes the message using 'ascii' as:
if isinstance(msg, str):
msg = _fix_eols(msg).encode('ascii')
The code works properly for Python 2 as the smtplib library for Python 2 does 
not have the above line and hence it allows Unicode characters in the Body and 
the Subject.

[issue35744] Problem in the documentation of numpy.random.randint in python 2.7

[Jay]

New submission from Jay :

Official Documentation of python 2.7 mentions that numpy.random.randint(a,b) 
will return a random integer from N such that a<=N<=b. But I have run the code 
and I have found that it never returns equal to b. So, what I did was I ran 
numpy.random.randint(0,1) for 50 milion times and finally printed the sum. 

The output was 0. 

I don't know if this a documentation or an implementation issue, but this is an 
issue which needs to be looked at. I am attaching the code that I ran.

[issue33722] Document builtins in mock_open

[Jay Crotts]

New submission from Jay Crotts :

The examples on using mock_open only include instances where objects are mocked 
in the REPL, so '__main__'.open is replaced. Commonly objects are mocked for 
use in other test modules, so builtins.open would be used instead.

A note about this in the documentation would be useful not familiar with python 
internals. I'm happy to do a PR for it.

[issue32642] add support for path-like objects in sys.path

[Jay Yin]

Jay Yin <jayyin11...@gmail.com> added the comment:

The issue was resolved by updating my version of the rest of the package 
apparently and remaking the whole thing, must have been some outdated stuff on 
my end causing the issue

[issue32642] add support for path-like objects in sys.path

[Jay Yin]

Jay Yin <jayyin11...@gmail.com> added the comment:

I've been stuck on "test_poplib" for over 149661 sec now, that's about 41 
hours... I don't think this is working correctly, although I'm unsure  what 
test_poplib is doing that has been affected by what I've changed here.

I'm unsure how to regenerate the files that interact with the code for sys.path 
as travisCI states
"
Generated files not up to date
 M Python/importlib_external.h
"
since my code changes some of how the importing is handled

[issue32642] add support for path-like objects in sys.path

[Jay Yin]

Jay Yin <jayyin11...@gmail.com> added the comment:

ok, so I found the PathFinder class you referenced, just making sure, this 
issue pertains to changing "self.path"'s usage and declaration to be a 
path-like object instead of the hard coded 'sys', 'path' returns? or is that 
part of it already?, also since this uses a tuple to keep track of the parent 
path, is there functionality in the path-like objects to find parent paths?

so what you're proposing, is that the function copy_file() itself, use

That's why I said to have the default be the old setting, so that any previous

I recently discovered in the documentation within the code and recent 
discussions with Barry, that ResourceLoader is deprecated and was wondering if 
we wanted to remove the code exclusively pertaining to ResourceLoader for 
clarity and to remove unused code. (PS if this is will be done I'll gladly 
contribute to doing so)

this would extend to set and get data right?, also would it be good to use the

os.path object to be handled separately?

[issue32667] Failing test_dtrace and test_subprocess on Ubuntu 16.04 on master

[Jay Yin]

New submission from Jay Yin <jayyin11...@gmail.com>:

Hello everyone,


I've been trying to build the master branch on Ubuntu 16.04 and it currently 
fails 2 test, I was wondering if this was normal or if I'm missing 
dependencies, I also tried apt-get build-dev python3.6 and python3.7 to no 
avail, the build requirements install worked for python3.5 but I suspect 3.7 
has different dependencies but I can't find where the documentation for the 
requirements are. 
2 tests failed:
test_dtrace test_subprocess


running test_dtrace as verbose gave https://pastebin.com/ZGzzxwjk

[Bash] FAILED (errors=4) test test_dtrace failed 1 test failed: test_dtrace R - 
Pastebin.com
pastebin.com


and running test_subprocess gives

[issue32495] Adding Timer to multiprocessing

[Jay Crotts]

New submission from Jay Crotts <crotts@gmail.com>:

I wanted to propose the addition of a Timer class to the multiprocessing 
library similar to the one that exists in the Threading module.

Timer provides an example of how to extend the Process class that might be 
helpful to beginners. 

The current lack of a Timer in the multiprocessing library could encourage 
newer programmers to use threads where processes would be more appropriate.

In the implementation below I have added the ability to specify a # of 
iterations that the timed function should execute, and an additional infinite 
argument that would make the process execute the given function until the Timer 
is explicitly stopped.

[issue30657] Unsafe arithmetic in PyString_DecodeEscape

[Jay Bosamiya]

Jay Bosamiya added the comment:

I've made a patch that should fix the vulnerability. Please do let me know if 
changes are required. Thanks a lot :)

PS: For anyone who looks at this later on, in my original message describing 
the issue, the line `*p++ = *s++;` should be marked as (4) instead to 
understand this issue better.

[issue30657] Unsafe arithmetic in PyString_DecodeEscape

[Jay Bosamiya]

New submission from Jay Bosamiya:

In Python 2.7, there is a possible integer overflow in
PyString_DecodeEscape function of the file stringobject.c, which can
be abused to gain a heap overflow, possibly leading to arbitrary code
execution.

The relevant parts of the code are highlighted below:

PyObject *PyString_DecodeEscape(const char *s,
Py_ssize_t len,
const char *errors,
Py_ssize_t unicode,
const char *recode_encoding)
{
int c;
char *p, *buf;
const char *end;
PyObject *v;
(1) Py_ssize_t newlen = recode_encoding ? 4*len:len;
(2) v = PyString_FromStringAndSize((char *)NULL, newlen);
if (v == NULL)
return NULL;
(3) p = buf = PyString_AsString(v);
end = s + len;
while (s < end) {
if (*s != '\\') {
  non_esc:
#ifdef Py_USING_UNICODE
[...]
#else
*p++ = *s++;
#endif
continue;
[...]
}
}
(4) if (p-buf < newlen)
_PyString_Resize(, p - buf); /* v is cleared on error */
return v;
  failed:
Py_DECREF(v);
return NULL;
}


(1) If recode_encoding is true (i.e., non-null), we have an integer
  overflow here which can set newlen to be some very small value
(2) This allows a small string to be created into v
(3) Now p (and buf) use that small string
(4) The small string is copied into with a larger string, thereby
  giving a heap buffer overflow

In the highly unlikely but definitely possible situation that we pass
it a very large string (in the order of ~1GB on a 32-bit Python
install), one can reliably get heap corruption. It is possible to
access this function (and condition in line(1)) through function
parsestr from ast.c, when the file encoding of an input .py file is
something apart from utf-8 and iso-8859-1. This can be trivially done
using the following at the start of the file:
# -*- coding: us-ascii -*-

The attached file (poc-gen.py) produces a poc.py file which satisfies
these constraints and shows the vulnerability.

Note: To see the vulnerability in action, it is necessary to have an
ASAN build of Python, compiled for 32 bit on a 64 bit machine.
Additionally, the poc.py file generated can take an extremely long
time to load (over a few hours), and finally crash. Instead, if one
wishes to see the proof of vulnerability quicker, then it might be
better to change the constant 4 in line (1) to 65536 (just for
simplicity sake), and change the multiplication_constant in poc-gen.py
file to be the same (i.e. 65536).

Proposed fix: Confirm that the multiplication will not overflow,
before actually performing the multiplication and depending on the
result.

"pandas" pronunciation

I hear people say it like the plural of "panda", and others as "panduss".  Is

You are correct.  Sorry I omitted that in my first post.  Thank you for your

I'm not using ISE.  I'm using a pre-edited script, and running it with the 
python command.

Consider the following simple script named hello.py (Python 2.7):

print "Hello"

If I enter:

python hello.py > out.txt

from cmd.exe I get a 6-character file (characters plus new-line).

from PowerShell I get an extract ^@ character after every character

SQL CE Database (.sdf) file connection with python

[Jay Desai]

Hello,

I am facing the following problem. Can anyone please provide some guideline?

Problem Statement: Extract data stored in the .sdf file to python. System 
config: Win 10 Pro 64-bit, python 3.5.2-64 bit, adodbapi library, SQL CE 3.5

I am fairly new to programming and I have picked up Python as my first language 
to learn. Currently, I have hit a wall in process of connecting a SQL CE 3.5 
.sdf file.

I have used the adodbapi library. I have searched the web extensively over the 
past week to find a solution to this problem and to make sure that my 
connection string is correct. I have tried multiple options/solutions provided 
on stack overflow and 
https://www.connectionstrings.com/microsoft-sqlserver-ce-oledb-3-5/.

Code:

import adodbapi

cons_str = "Provoider=Microsoft.SQLSERVER.MOBILE.OLEDB.3.5;" \
   "Data Source=D:\Work\Programming\Python\SQL_DataTransfer\LF.sdf;"\
   "Persist Security Info=False;" \
   "SSCE:Max Database Size=4091"

connection = adodbapi.connect(cons_str)
print(connection)

Error Message: Traceback (most recent call last): File 
"D:\Work\Programs\Python35.virtualenvs\sql_output\lib\site-packages\adodbapi\adodbapi.py",
 line 93, in make_COM_connecter c = Dispatch('ADODB.Connection') #connect after

Problem with difflib SequenceMatcher

[Jay]

Hello

I am having an odd problem with difflib.SequenceMatcher. Sample code below:

The strings "src" and "trg" differ only a little. The
SequenceMatcher.ratio() for these strings 0.0. Many other similar
strings are working fine without problems (see below) with non-zero
ratios depending on how much difference there is between strings (as
expected).

Tested on Python 2.7 on Ubuntu 14.04

Program follows:
---
from difflib import SequenceMatcher as SM

src = u"N KPT T HS KMNST KNFKXNS AS H KLT FR 0 ALMNXN AF PRFT PRPRT AN
RRL ARS T P RPLST P KMNS H ASTPLXT HS ANTSTRL KR0 PRKRM NN AS 0 KRT LP
FRRT 0S PRKRM KLT FR 0 RPT TRNSFRMXN AF XN FRM AN AKRRN AKNM T A SSLST
ANTSTRL SST"
trg = u"M KPT T HS KMNST KNFKXNS AS H KLT FR 0 ALMNXN AF PRFT PRPRT AN
RRL ARS T P RPLST P KMNS H ASTPLXT HS ANTSTRL KR0 PRKRM NN AS 0 KRT LP
FRRT 0S PRKRM KLT FR 0 RPT TRNSFRMXN AF XN FRM AN AKRRN AKNM T SSLST
ANTSTRL SST"
print src, '\n', trg, '\n', SM(None, trg, src).ratio()
---


The following sequence prints a ratio() of 0.989795918367 which seems
about right.
---
src = u"M STNK AS AN AF 0 MST AMPRTNT LTRS TRNK 0 TNT0 SNTR HS MST
PRMNNT AKMPLXMNT AS 0 ASTPLXMNT AF 0 PPLS RPPLK AF XN HS A0R AXFMNTS
ANKLTT LTNK HS PPL AN 0 LNK MRX AFR FR 0SNT MLS T KP 0 KMNST MFMNT
ALF"
trg = u"M STNK AS AN AF 0 MST AMPRTNT LTRS TRNK 0 0 SNTR HS MST PRMNNT
AKMPLXMNT AS 0 ASTPLXMNT AF 0 PPLS RPPLK AF XN HS A0R AXFMNTS ANKLT
LTNK HS PPL AN 0 LNK MRX AFR FR 0SNT MLS T KP 0 KMNST MFMNT ALF"
print src, '\n', trg, '\n', SM(None, trg, src).ratio()
---

What could be the cause? Is there something I am doing wrong?

Thanks in advance

Re: the best online course

[Jay Thompson]

There are a ton of great resources on
https://wiki.python.org/moin/BeginnersGuide . The resource I generally
recommend to people first is "Learn Python The Hard Way" @
http://learnpythonthehardway.org/ . The course is $29.95 and worth every
penny but if you can't afford it the author has made the course available
for free. Just scroll to the bottom of the page to find the link.
