Discussion

• How to update daily builds to Qt 6.2
  • Need sufficient testing before putting in daily build.
  • Shell does not work. Uses qtconsole which uses qtpy 1.11 shim which does not support PyQt6. qtpy 2.0 scheduled for Dec 22 release supports pyqt6.
  • Using enumeration values without enumeration name needs a better solution.
    • Our prereqs/qtshim code just adds the enumeration values our code uses.
    • That won't work for outside developers.
    • Eric suggests having our shim import and use qtpy classes to handle enumerations.
  • Greg suggests making separate cron job that builds qt6 daily build, putting it in a separate directory, and shown on a separate download page.
  • Tristan and Tony Schaefer might want to try the Qt6 version before goes into daily build.
  • Greg says Qt 6 requires macOS 10.14 minimum. Our builds currently use 10.13.

• Update prereqs
  • Prereqs besides Qt can be updated now that 1.3 is released.

• Chimera 1.16 release
  • Greg will try making it tomorrow.
  • Eric will announce to chimera users.
  • Last Windows 7 release since no security patches for Windows 7 last 2 years.
  • Also Greg says cygwin dropped support for Windows 7.
  • Windows 7 users can stick with 1.16 and older releases.

• Trac reliability
  • We are currently using Trac 1.2, latest stable is 1.4, prerelease is 1.5, all Python 2 based.
  • If we update from 1.2 to 1.4 would need to see if plugins we use are available.
  • We have already updated email2trac to latest.
  • Greg is interested in trying replacing sqlite with mysql since problem is often "database malformed".
  • Python 3 Trac is on the horizon possibly 1.6.
