• Chimera
  • Chimera 1.16 release.

Discussion

• Simplifying Linux ChimeraX distribution
  • Chimera has just one linux distribution, includes ancient versions of all libraries and monkey patches python stuff.
  • ChimeraX has multiple Linux distributions and uses system packages.
  • Greg would like to investigate having a single flatpack Linux distribution.
  • Current linux downloads are only 14% of all downloads (51% Windows, 34% Mac).
  • Users reported ChimeraX install not working on Debian 10.
    • Should remove llvm dependency from Ubuntu 18 ChimeraX to fix this.

• ChimeraX 1.3 release
  • First release candidate was on download page Monday October 25.
  • Four active tickets
    • Download page is done.
    • ffmpeg on linux missing libbz2 dependency is done.
    • Command to install pypi packages, nice but not required for 1.3
    • WebProfile warnings on exit, nice to fix for 1.3 but not required.
  • Greg will add ticket for adding checkbox to update gui so users who cannot update to 1.4 can stop being reminded about it. This is needed for 1.3 release.
  • Eric fixed a couple major bugs in release candidate yesterday.

• Package updates for ChimeraX 1.4
  • Python 3.10 out, requires OpenSSL 1.1.1 which is not installed on older Linux.
  • Probably stick with Python 3.9 for next release.
  • Might try to switch to Qt 6 for ChimeraX 1.4 release in 6 months. Will need extensive testing.
  • Greg will make PyQt 6.2.1 licensed wheels.
  • Tom will fix Qt 6 namespace (QAction and enumeration value) compatibility

• Automatic testing when code changes
  • Zach setup automatic testing on the cxservices backend github repository.
  • Tests run whenever new commit made or pull request made.
  • Tests include job id, polling interval, blast, ....
  • Zach will present at a developer meeting how this is setup, how results are shown, what tests look like, details of how this works.

• Chimera 1.16 release
  • macOS 12 Monterey released last Monday. Chimera passed 3 minutes of basic hand testing.
  • Try for Chimera 1.16 release November 29 after users have had a chance to try it and report bugs with macOS Monterey.
  • We will skip release candidates since daily build serves that purpose and changes infrequently. Daily build will just be promoted to an official 1.16 release.

Action Items

• Git remove hydra, wsgi, llgr and other unused directories to avoid confusing new developers. Tom
• Remove pkg-config prereq if it is not being used for builds. Tom
