The unattended-upgrades mechanism updated python3 earlier today on our servers, leading to incompatibilities between running python stdlib code and updated stdlib code. This is not a bug in Frappe.

Regression: ImportError for `HeaderWriteError` in long-running process post-Python update for CVE-2024-6923

opened 12:02PM - 17 Sep 24 UTC

# Bug report ### Bug description: Pull request #122233 introduced a new class …`HeaderWriteError` in commit 097633981879b3c9de9a1dd120d3aa585ecc2384 and imports that from `email.generator`. This breaks running applications that have imported other parts of `email` before the update, and then try to import the generator past the update. Now this is a bit silly, but it is what `email.message.Message.as_string()` does, it imports `email.generator` *inside* the function - which may happen at any point of the program run-time rather than at startup. For example, the following pseudo-code will fail, assuming it has not generated another email earlier or manually imported the `email.generator` module. ```python import email.message <do something for a long time, such as wait for a web form, Python is being upgraded here> msg = <prepare a message> msg.as_string() ``` A particular instance of the issue is the `unattended-upgrades` package in Ubuntu and Debian, which will install the security update and then may send an email and fail there due to the ImportError, see https://bugs.launchpad.net/ubuntu/+source/python3.8/+bug/2080940. I'm wondering if it's feasible to add a workaround to the stable branches: Cchange the email.generator module import: ```python from email.errors import HeaderWriteError ``` to graciously support the previous version email.errors: ```python try: from email.errors import HeaderWriteError except ImportError: from email.errors import MessageError as HeaderWriteError ``` This is a safe change, existing applications, where the import fails can't be having `except HeaderWriteError` statements anyway. Thanks. ### CPython versions tested on: 3.12 ### Operating systems tested on: _No response_

work for me. thank you. Seft hosted servers, and affected python versions are 3.10.x (v14 and v15 bench) and 3.9.x (v13 bench) but no issue on 3.11.x (v15 bench).

Hello,

Just bench restart is enough to get rid of this error.
However, it needs to be done as this error has the capacity to block every method once.

elvis_ndegwa · September 18, 2024, 8:18am

for a solution run the below

sudo pip install --upgrade urllib3

and also this

pip install --upgrade requests

this should fix it

Just bench restart it solved.

bench clear-cache && bench restart solved my problem.

I can open Email Queue, Email Account and Email Domain doctypes. And I’ve sent a test email to myself.

I don’t understand the real cause here. If a python package have some problems, it should not be fixed by just restarting the bench.

supervisorctl stop all
supervisorctl start all

Above command worked for me. Thanks.

Based on my tests prior to the restart it seems like this error appear only once per method and restarting allow to restart all methods at once, thus removing the error for all.

To be more precise about what I experienced :
On login : a method in error due to emails.errors
Refresh
HTML 500 error
Refresh
another method in error due to emails.errors
Refresh
yet another method in error due to emails.errors
Refresh
yet another one

So once a method has failed once it indeed didn’t fail anymore.

I suspect it is linked to Regression: ImportError for `HeaderWriteError` in long-running process post-Python update for CVE-2024-6923 · Issue #124170 · python/cpython · GitHub

In my case I just try 2 command which actually work.

bench update --patch
bench migration

NB: I am in Production mode .

I tried these commands, but it did not solve the issue.
