Discussion

• Broken Linux builds
  • Greg fixed them today.
  • Problem was with fakeroot support using singularity.

• Tristan can't log in to Trac
  • Zach notes he cannot log in using Chrome.
  • Greg and Tom confirm Trac login from Chrome fails, Firefox works.
  • Greg thinks it might be a Kerberos configuration issue. Says Scooter would need to look at that.
  • Greg sent Tristan email warning that Chrome login does not work.
  • If Trac login fails for Tristan in Firefox then possibly authentication for web-only accounts is not enabled in Apache. Greg says that would be a Scooter issue.

• Update ChimeraX from Python 3.9 to 3.11
  • Decided we are ready to merge Zach's Python 3.11 branch for daily builds, after asking Tristan if it is ok with him.
  • Tom will ask Tristan today so we can hopefully go to 3.11 tomorrow.
  • Zach fixed Wayland Python 3.11 problem caused by updated PyOpenGL 3.1.6 trying to automatically use EGL. Zach changed code to explicitly ask for x11 PyOpenGL since EGL has some problems.
  • Zach showed Python 3.11 changes. Several places in C++ use ssize_t which he had to change to Py_ssize_t since Windows does not have the posix ssize_t.

• ChimeraX library distribution
  • Zach asks if making a macOS PyPi distribution initially is an ok plan (instead of Linux). All agreed that is fine.
