Proposal: stable-ABI compatibility ELF note for Torch extensions

What this is

A prebuilt torch extension (.so) gives no hint about which version of the PyTorch stable ABI it was built for. Today the only way to find out is to load it against a specific libtorch and see whether it works. This proposal embeds a small piece of metadata in the extension at build time that records the answer up front: the minimum stable-ABI version the extension needs.

SQLite ABI Compatibility and WAL-Reset Bug Notes

Is it safe to upgrade libsqlite3.so.0?

Yes. SQLite maintains strict backwards ABI compatibility within the libsqlite3.so.0 soname. From the official documentation:

Stable interfaces will be maintained indefinitely in a backwards compatible way. An application that uses only stable interfaces should

    "flit-core==3.12.0",
    "milvus-lite==2.5.1",
    "pdm-backend==2.4.5",
    "poetry-core==2.1.3",

CPython WASM

CPython

>>> import sys, os, platform
>>> sys.platform
'emscripten'
>>> os.name
'posix'

UPDATE

The workaround is no longer needed with recent alsa-ucm, e.g. alsa-ucm-1.2.11-2.fc39. Just configure the device to use Default Alsa Profile instead of Pro.

old workaround

cp /usr/share/pipewire/media-session.d/media-session.conf ~/.config/pipewire/media-session.d/
add loopback modules to context.modules section
configure interface to use Pro Audio profile
systemctl restart --user pipewire.service pipewire-pulse.service

On each IPA server (server.ipa.example)

Apply patch https://github.com/freeipa/freeipa/pull/5496/files (https://pagure.io/freeipa/issue/8686). on RHEL it's in /usr/lib/python3.6/site-packages/ipaserver/plugins/cert.py
systemctl restart httpd.service to reload server code with patch
ipa host-add proxy.ipa.example --force
ipa host-add-managedby proxy.ipa.example --hosts=server.ipa.example
Create /tmp/fake-kdc.update (replace proxy.ipa.example with your actual proxy name three times)
Create fake KDC entry in masters configuration ipa-ldap-updater fake-kdc.update
systemctl restart httpd.service
request new KDC cert for server's and proxy's DNS name: ipa-getcert resubmit --wait -f /var/kerberos/krb5kdc/kdc.crt -D proxy.ipa.example -D server.ipa.example
