From previous meeting(s)​

Your new agenda items​

  • (FF) Python 3.9 update?

  • (Eli Rykoff, IF) update on osx arm64 and code signing

    • (ER) Got ARM packages running when the machine was received. Updated to latest Big Sur and everything broke. All dylibs and so's need to be signed for the OS to run them. Can be ad-hoc signature but it needs to be signed. Latest apple tools will autosign these tools (clang will produce an autosigned binary). Making things relocatable invalidates the signature. For arm64 binaries you run a signer tool and then things are able to run on it.
    • (IF) On Linux there's a tool to run so we can cross-compile from linux. On mac there's a system tool that's usable.
      • Q: Does the signer system tool come with the bare system or with XCode? ER will confirm where this signer comes from.
    • (JH) Conda changes the binary when it does prefix replacement. Do we need to disable prefix replacement?
      • (CL) Prefix replacement for libcrypto.dylib, libssl.dylib, openssl executable.
    • (CL) Will Apple require an official signer cert?
      • (ER) Release notes seem to indicate that self-signed certs are ok (for now).
      • (ED) Can Anaconda ping Apple to see if they're planning on changing this by release time?
    • (WV) Can we redistribute the signing tool?
      • (IF) Conda will need to depend on this signing tool if we're going to resign at install time
    • (MB) Do x86 packages also require signed packages?
      • (MRB) Only things on apple silicon will require this signing

  • (WV) ruby 2.7 can track features be removed with some other mechanism?

  • (WV) update on boa & quetz

  • Shout-out on twitter at some point. "Thanks forOVHCloud for providing a VM", etc. (maybe after we ship qt on windows with it?)

  • Figure out how to communicate breaking changes to users. Likely should open up an issue immediately for futher discussion. Ping @kkraus, plus capture notes from further up in these meeting notes

  • John K. will update the cuda toolkit feedstock on the git repo to note the NVBug link to the internal NVIDIA issue tracker

  • Jonathan will update docs to note that some non-exhaustive list of packages (like cuda-toolkit, MKL, etc.)

    • who's the POC for CF <> Anaconda, CF <> NumFocus, CF <> Azure
    • who's the POC for the various subteams?
    • Informal information: roles, day jobs, bios, the whole nine yards, why you're here, etc.
    • Public or internal? I don't really care either way. Anyone feel strongly one way or the other?
    • opt-in to public bios

    • some concern about "yet another place to keep stuff up to date"
