Cannot generate token about gmail-oauth2-tools HOT 8 CLOSED

The same issue has been reported to offlineimap :
OfflineIMAP/offlineimap#655

from gmail-oauth2-tools.

OpenSSL EOF detection behavior is being reverted in 1.1.1, so I expect this to start working once that is released. However, the change to EOF detection is being kept on for OpenSSL release 3.0. This should give the maintainers of this application time to fix the issue before OpenSSL 3 is released. I suggest this issue not be closed until this API is fixed to work with the new EOF detection code.

openssl/openssl@6611672

Revert the change of EOF detection while reading in libssl to avoid
regressions in applications depending on the current way of reporting
the EOF. As the existing method is not fully accurate the change to
reporting the EOF via SSL_ERROR_SSL is kept on the current development
branch and will be present in the 3.0 release.

@alexDarcy Hi, I've got the identical problem. Doesn't seem like this repo is maintained by anybody though.

After some digging I found out that it may be related to openssl version: http://marine.copernicus.eu/faq/what-are-the-motu-and-python-requirements/ (error identical).

On my system both versions are installed:

pacman -Ss openssl                                                                                                                         
core/openssl 1.1.1.e-1 [installed]
core/openssl-1.0 1.0.2.u-1 [installed]

Unfortunately newest one is required by a lot of other important packages so removing it is not an option.

Right now I didn't found any easy solution to get python2 use older version of openssl. Playing around with openssl options didn't give any result for now:

  sslcontext=ssl.create_default_context()
  sslcontext.options |= ssl.OP_NO_SSLv3

  response = urllib.urlopen(request_url, urllib.urlencode(params), context=sslcontext).read()

According to docs, newer openssl support was added relatively recently:

Changed in version 2.7.13: Updated to support linking with OpenSSL 1.1.0

So, probably I will try to downgrade python2 as last resort. Also, rebuilding may be an option: https://stackoverflow.com/questions/5937337/building-python-with-ssl-support-in-non-standard-location.

Let me know if you find any solution.

rolling back openssl is risky and shouldn't be recommended. Who is the maintainer of this repo? Google?

@JonnyMako Thanks. I will wait for 1.1.1f and then upgrade openssl.

After upgrade to 1.1.1f issue is gone.

I can confirm this, closing the issue.
