Discussion

• Linux nightly build broken
  • It looks like the builds are actually working.
  • But the last commit date was April 27 instead of June 30 because the build tools extracted the wrong date from github and Zach had pushed a branch from April 27 on June 30 which was the most recent commit.
  • Greg will fix the build tools script to get the correct date.
  • This also explains why Elaine noted that ChimeraX reports the current daily build is from April 27 at start up.

• Toolshed disk quota error updating a bundle
  • Scooter fixed this increasing the toolshed disk quota from 1 byte to 100 GB.

• Mac dual display crash
  • Tom tested for half hour on 2 displays, could not produce crash.
  • Next let's try update to PyQt 6.5.1. This crash started in Qt 6.4 and if we are lucky it has been fixed.

• mmCIF out of memory errors
  • Eric says we have not had reports of daily build giving mmCIF out of memory since Greg fixed a memory leak.
  • Greg tempted to make a 1.6.2 release to test this fix.
  • Eric thinks the fix is unlikely to be the problem since the errors are only Windows and the leak fixed was on all platforms.

• Chimera 1.17.2 release
  • Not yet made because of some Python 2/3 issue with bytes and strings in the script that makes the release.
  • Greg will fix it.
