[issue41791] mimetypes module does not recognize jp2 type

[Radim Novotny]

Radim Novotny  added the comment:

Hi Andrés,

tried again and the difference is between 3.7.4 and 3.7.5
The jp2 mimetype is read from /etc/apache2/mime.types (see knownfiles in 
mimetypes.py) so the mime type does not have to be in the mimetypes.py 
hardcoded, but in version 3.7.5 it stopped working. 

I think it's because of using _types_map_default instead of types_map in some 
places.

Since jp2 is an official mime type it should be added to the list but I also 
think we should try to identify the issue with _types_map_default.

Seems to be related to https://bugs.python.org/issue4963

I will have look if I can find out what was changed and why.

Cheers,
Radim

[issue41808] Synchronize What's New in 3.9 master and 3.9 copies

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The 3.9 copy (only) of What'New 3.9, line 882 has duplicated words 'deprecated 
deprecated'.  I made a branch off of updated 3.9 to fix this and pushed to my 
fork, but github repeated refuses to make a PR (against 3.9), giving me the 
unicorn page instead.
https://github.com/terryjreedy/cpython/tree/3.9-dedup

If this were fixed, the two copies would be identical.

[issue41808] Synchronize What's New in 3.9 master and 3.9 copies

[Terry J. Reedy]

New submission from Terry J. Reedy :

The 3.9 copy is 5 lines longer, meaning that after the b1 split, something was 
added to 3.9 directly instead of to master first and backported, or added to 
both and deleted from master.

Lukasz, is checking the two copies part of the final release process?

The 5 lines not in master are from PR-21012 and PR-21039 of issue 40939, by 
Lysandros and Pablo.  Please one of you verify that they should be added to 
master, as in the PR I will add, and not deleted from 3.9.

[issue41807] Warnings when installing Linter on VS code on Linux and Windows.

[zamunda]

New submission from zamunda :

nstalled VS code, installed Python extension and when it loaded a pop up showed 
"Linter is not available" or something like that. Press Install, choose linter 
or never show again options.
Pressed Install - and it loaded the code to install it. It installed some stuff 
but there are errors about Path or something. See in the screenshot.
I've never had such Warnings before.

When I installed Python (on my system Windows) I put a checkmark on Add to 
Path, so it's not the problem.

Then I moved to Linux hoping it will work better and without warnings. Same 
Warining there too.

I guess there is a problem with python3-pip or something.

[issue41756] Do not always use exceptions to return result from coroutine

[Yury Selivanov]

Yury Selivanov  added the comment:

> Does it sound correct?

It does, but given the amount of back and forth on this, I'd wait for Serhiy 
and Stefan to confirm if they're OK.

IMO the `PyIter_Send` name is OK (given how generic the implementation will be) 
and returning an enum, while a tad unconventional for the C API is way more 
convenient for the developer.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The backport to 3.9 is still pending.  The bot claims that there is a merge 
conflict.  This should not happen because What's New in 3.9 should be identical 
in master and 3.9.  My guess is that someone only changed it in 3.9, though 
another change in master might not have been backported.  I will try to 
determine the problem.

[issue41791] mimetypes module does not recognize jp2 type

[Andrés Delfino]

Andrés Delfino  added the comment:

Hi, Radim!

I've tested with 3.7.8 and got (None, None). I'm curious on how you got that 
'image/jp2' output.

It seems jp2 was never supported by looking into the git history of 
Lib/mimetypes.py.

Would you like to open a PR to support it? :)

[Andrés Delfino]

Andrés Delfino  added the comment:

Hi, Patrick! Yes! It would be great if you could open a PR to document those 
new types.

The documentation of types.Union should go to master only, and the 
documentation of types.GenericAlias to both master and 3.9, so two PRs should 
me opened to address this issues separately.

The backporting (yes! that's the word) to 3.9 will be (fingers-crossed) 
automatic thanks to Mariatta's https://github.com/python/miss-islington

[issue41800] Python installation fails when run under system account if there is already an existing installation on the system already

[Steve Dower]

Steve Dower  added the comment:

Yeah, this whole issue is basically because Burn (our installer tool) won't do 
per-machine bundle registration even when it's only installing per-machine 
packages. So the install block that it would normally throw up  fails if you 
use a different user account to install it the second time.

> (Python gets installed as a step in one of our installers)

I'm intrigued by this - if Python is a dependency of your application, it's 
better to repackage it yourself and install to your own directory. The 
installer is basically there for end-users, but if you're not doing an end-user 
kind of install there's really nothing gained.

This whole scenario is fairly under-developed though. It comes up quite 
infrequently, so we don't have any really convenient instructions on how to go 
about it. Doesn't mean we can't help, but because we don't have a clear idea of 
what you may be trying to achieve, we'd like to hear about it before telling 
you how to approach this kind of thing.

[issue29099] sqlite3 timestamp converter cannot handle timezone

[Hassanbot]

Hassanbot  added the comment:

This still isn't fixed as of 3.8 (or in master I think).

I can understand why you wouldn't want to allow serializing and deserializing 
time zones, since tzinfo objects cannot be accurately serialized with a simple 
UTC offset, but you should at least get an error when trying to insert an aware 
object. Anything is better than it is now, where you get no warning or error 
when inserting the object, and get a hard to interpret error ("invalid literal 
for int() with base 10") when trying to retrieve it.

For deserialization, the datetime class now (since 3.7) includes a 
fromisoformat() method that could be used as a counterpart to the isoformat() 
method used when serializing. At least it would be consistent then.

[issue41756] Do not always use exceptions to return result from coroutine

[Vladimir Matveev]

Vladimir Matveev  added the comment:

so to summarize:

Proposed function signature:
```
PySendResult PyIter_Send(PyObject *obj, PyObject *arg, PyObject **result);
```

For generators/coroutines function will delegate to specialized implementation 
that does not raise StopIteration exception
For types that provide `tp_iternext` if arg is Py_None function call invoke 
`Py_TYPE(obj)->tp_iternext(obj)`
For all other cases function will try to call `send` method

Regarding of the case function will not raise StopIteration and will always 
return pair status/result.

Does it sound correct?

I like `PyIter_Send` (and why I initially proposed it myself) because it will 
also work with the "send" slot defined on some types if we end up adding one.

[issue41806] socket methods with timeout take very slow path on Windows

[Steve Dower]

New submission from Steve Dower :

When a socket object has a non-zero timeout, all send/recv/etc. calls are 
preceded by a select() call before making the actual call. If there is no 
timeout, the select call is skipped.

It appears that on Windows, select() will block until the previous operation 
has completed, even if the next one would reliably succeed. For example, 
http.client uses a default blocksize of 8192 bytes (which is _really_ small for 
2020, but probably not for 2002 when it was set - can we just increase it?), 
which will break up a stream into many little chunks.

With no timeout set: send() is called repeatedly and Windows buffers blocks 
internally, resulting in the actual sends being bigger (as seen with a network 
trace - they'd range from 8KB-50KB).

With a timeout set: select() is called and waits for the previous send() to 
complete, then calls the next send(). This results in every single send being 
exactly 8KB.

This latter case also results in every operation becoming essentially 
synchronous, instead of picking up some implied parallelism in the OS and 
network driver. (Yes, increasing the block size in the above example also 
helps, but doesn't prevent the issue in the first place, nor does it help with 
other cases.)

Has anyone ever looked into alternate ways to have the timeout work here? Such 
as SO_SNDTIMEO? I don't want to force through a full redesign here, but getting 
the select() call out of the main path here seems like an easy win.

Would anyone like to take a look? I'm happy to help mentor someone through a 
patch (as long as you're familiar with networking/sockets already).

[issue41805] types.GenericAlias and types.Union have no documentation

[Patrick Reader]

New submission from Patrick Reader :

See title.

For reference:

`GenericAlias` was added by Guido van Rossum  in commit 
48b069a003ba6c684a9ba78493fbbec5e89f10b8 "bpo-39481: Implementation for [PEP 
585](https://www.python.org/dev/peps/pep-0585/) (#18239)"

`Union` was added by Maggi Moss  in commit 
1b4552c5e8e925f24c15f707050f22c977171125 "bpo-41428: Implementation for [PEP 
604](https://www.python.org/dev/peps/pep-0604/) (GH-21515)"

I can do a PR which would need backporting (is that the right word?) to 3.9 at 
least for `GenericAlias`.

[issue41794] Memory leak in asyncio server

[Bale]

Bale  added the comment:

Ok since nobody is replying, the bug seems to be that if the asyncio server 
sends data, and I do not use s.recv() to clear the buffer, and I use s.close() 
instead, a reference to handle_echo is kept and is never deleted.

Using gc.collect() does delete the leaked object. 

The socket that you use to connect to the server seems to also determine 
whether the bug works, like how I can not do it when I create the connection on 
my windows computer, but the bug is triggered when I do it on my ubuntu server. 
I should also mention that I am running the asyncio server on my ubuntu server, 
on python 3.8.

Here is output of the bug happening.
FROM CLIENT ON MY WINDOWS COMPUTER ON PY3.8:
>>> s = socket.socket()
>>> s.connect(("x.x.x.x", ))
>>> s.send(b"test")
4
# Wait for server to send data, but dont use s.recv(), just assume
>>> s.close()
Server output:
Received 'test' from ('x.x.x.x', 42241)
Send: 'test'
connection lost
DELETED OBJECT

After connection was lost, DELETED OBJECT was printed, so everything worked 
fine. But when I create the socket in a different environment, such as on 
ubuntu python 3.8:
Client side code (exact same as before):
>>> s = socket.socket()
>>> s.connect(("x.x.x.x", ))
>>> s.send(b"test")
4
# Wait for server to send data, but dont use s.recv(), just assume
>>> s.close()
Server side output:
Received 'test' from ('x.x.x.x', 42249)
Send: 'test'
connection lost

We can see that connection lost was printed, but DELETED OBJECT was not. This 
is evidence that there is a memory leak bug with asyncio.start_server

[issue41756] Do not always use exceptions to return result from coroutine

[Mark Shannon]

Mark Shannon  added the comment:

I agree with Serhiy, that `PyGen_` is a bad prefix.

Unless a function takes generator objects and *only* generators objects, then 
it shouldn't have a `PyGen` prefix.

The API function is the C equivalent of obj.send(val).
The first parameter is an object.

Coroutines do not inherit from generators.
That the the C implementations are so coupled is an unfortunate historical 
accident, and may well be changed.

Regardless of how this is implemented internally, any API function's signature 
should reflect the equivalent Python code.
And please use an enum, not an int, as the return value. It's a huge boon for 
readability.

I would suggest:
`PySendResult PyIter_Send(PyObject *obj, PyObject *arg, PyObject **result);`

[issue39452] Improve the __main__ module documentation

[Géry]

Géry  added the comment:

I agree with you Terry. Another thing that bothers me: in the current document, 
the __main__ module is reduced to its environment (aka context or dictionary), 
whereas a module object has other important attributes such as its code.

So how about adding the following changes?

- :mod:`__main__` --- Top-level code environment
- ==
+ :mod:`__main__` --- Startup module
+ ==

-:synopsis: The environment where top-level code is run.
+:synopsis: The first module from which the code is executed at startup.

- ``'__main__'`` is the name of the environment where top-level code is run.
+ ``'__main__'`` is the name of the startup module.

- A module can discover whether or not it is running in the main environment
+ A module can discover whether or not it is initialized as the :mod:`__main__` 
module

I don't recommend changing /etc/ssl/openssl.cnf. Instead, make a local copy,

Vladyslav Bondar. Then run the tests with:

And I'm attaching some of the Python installer logs I found from one of the 
debugging sessions researching this problem. It contains logs from a  few 
installation runs and you can see there from the first log file in each batch 
and from the names of the other log files that the initial two failed while the 
last one was presumably done after an uninstall and worked.

[issue41800] Python installation fails when run under system account if there is already an existing installation on the system already

[Jurko Gospodnetić]

New submission from Jurko Gospodnetić :

This issue seems to affect all Python 3 Windows installers.

Reproduced on:
- various Windows 10 systems
- one Windows 8 system
- one Windows 7 system
- all tested Python 3+ installers up to and including 3.8.5

Scenario:
1. there is already an existing Python 3+ installation on a Windows system, 
installed for all users
2. you run a Python 3+ installer (any version, even the one matching the 
already installed Python version) under the `systemprofile` Windows user 
account, targeting all users and the same target folder that the currently 
existing installation is located in
- example how to do this manually:
- using the Microsoft/SysInternals `psexec` utility to open a command 
prompt running under the `systemprofile` Windows user account:
  `psexec -i -s cmd`
- run the Python installer from that command-prompt, in our case it was the 
following command:
  `python-3.8.5.exe /passive TargetDir=C:\Python38 InstallAllUsers=1 
PrependPath=1`
3. result will be any of the following at random:
- failed installation with different Windows error codes, including totally 
opaque 0x80070643 `Fatal Error during installation`
- successful installation
- seemingly successful installation that does not really install all the Python 
components, e.g. the whole `Lib` folder may end up being empty
- seemingly successful installation that then can not be uninstalled as the 
uninstaller reports that it can not find the existing installation on the system
  - this effect can often, but not always, be fixed by rerunning the installer 
and then running the uninstaller
- you can run the uninstaller from the command-line using something like:
  `python-3.8.5.exe /uninstall /passive`

Additional notes on produced results:
- each installation seems to generate differently named log files in the 
`C:\Windows\Temp` folder, i.e. the `systemprofile` user account's `%TEMP%` 
folder
- the log file names indicate whether each specific component is being 
installed for the current-user or all-user variants, and those seem to be 
chosen at random in our problematic scenario
- it seems like the components whose log files are marked as being installed 
for the current user are not getting installed at all, or may possibly be 
getting installed to some other undisclosed location

The same does not occur if any of the following is true:
- if the installation is run from an regular end-user account
- if there is no Python currently installed on the system

A workaround we found in our case (Python gets installed as a step in one of 
our installers) is to basically do (uninstall, install) in a loop with some 
hand-crafted checking to see if the existing installation is ok (includes 
running some Python code + checking for some specific Python distribution files 
we've found to be missing in some scenarios).

It was already removed in issue37328. The only not applied part of the patch is 
adding a What's New entry.

[issue39452] Improve the __main__ module documentation

[Terry J. Reedy]

Terry J. Reedy  added the comment:

The main issue I have with the existing doc is its use of 'top-level' to mean 
the main, initial, startup module that first executes the user code for a 
python 'program'.  We routinely use 'top-level' instead for the global scope of 
a module.  Example: https://docs.python.org/3/glossary.html, 'qualified name' 
entry, line 2: "For top-level functions and classes, ..."  Within '__main__', 
some code is top-level, but class and function bodies are not.

But this does not have to be part of this PR.
