Agenda

• ChimeraX
  • Make ChimeraX 1.4 release candidate now?
  • Are Windows open dialog crashes fixed?
  • Upgrade Trac to mysql for better reliability.
  • Is Windows crash reporting ever useful? Should we disable it? Will Qt 6.2 fix spurious file dialog errors?
  • Should we remove pywin32 (20 MBytes) and wmi used only to report computer model in bug reporter on Windows? Ticket #5528
  • Task termination at app quit
  • Rename ChimeraX.exe on Windows?
  • Should we go to Python 3.10 in 1.5?

Discussion

• Drop CentOS 7 for ChimeraX 1.4?
  • SBGrid has half ChimeraX users (220/440) on CentOS 7 in last 6 months
  • Greg tried compiling Qt 6 on CentOS 7, core worked, web engine failed with gcc 10
  • Greg will try gcc 9 to compile Qt 6.
  • If compile fails we make ChimeraX 1.3 the last CentOS 7 release

• How can Tristan compile ISOLDE for old Linux?
  • Tristan updated his CentOS 7 desktop to Ubuntu 20.
  • Uses CentOS 7 virtual machine to compile ISOLDE for toolshed.
  • Greg suggests using singularity image would be simpler.
  • Discussed providing no-gui CentOS 7 ChimeraX without Qt for plugin developers to build against.
  • Greg suggested providing Docker image of ChimeraX CentOS 7 build environment.
  • Discussion with Zach of continuous integration / cloud builds of ChimeraX being used by plugin developers who need to compile code.

• Windows open dialog crashes
  • Got one Qt 6.2 windows open dialog crash, might be rare
  • Will continue look for this crash until about a week before release, then remove Windows crash reporting since it has not been useful (Eric and TomG concur).

Action Items

• Update ChimeraX to Qt 6.3.0. Greg
• Present github continuous integration tutorial. Zach
• Remove pkg-config prereq if it is not being used for builds. Tom
