Re: [bitbake-devel] [PATCH] fetch2/wget: reuse cached HTTPS connections

Thanks Mathieu,
Python 3.12 removed the HTTPSHandler._check_hostname attribute, I'm will post a v2 patch shortly.

Kind regards
Fredrik

Hi Fredrik,

Thanks for your patch.

It looks like this is failing to build here:
ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
    Following is the list of potential problems / advisories:

    'CacheHTTPSHandler' object has no attribute '_check_hostname'.
    Please ensure your host's network is configured correctly.
    Please ensure CONNECTIVITY_CHECK_URIS is correct and specified URIs are available.
    If your ISP or network is blocking the above URL,
    try with another domain name, for example by setting:
    CONNECTIVITY_CHECK_URIS = "https://www.example.com/"    You could also set BB_NO_NETWORK = "1" to disable network
    access if all required sources are on local disk.

Can you have a look at the issue?

Thanks,
Mathieu
