DIALS releases in PHENIX

Hi Folks Following from - # select dials-3.5 branch + # select dials-3.2 branch def _add_git(self, module, parameters, destination=None): super(PhenixBuilder, self)._add_git(module, parameters, destination) if (module == 'dials' or module == 'dxtbx' or module == 'xia2') and self.python3: @@ -2339,9 +2339,9 @@ class PhenixBuilder(CCIBuilder): if module == 'dxtbx': self.add_step(self.shell(command=['git', 'remote', 'set-url', 'origin', 'https://github.com/dials/dxtbx.git'], workdir=workdir)) self.add_step(self.shell(command=['git', 'fetch', 'origin'], workdir=workdir)) - self.add_step(self.shell(command=['git', 'checkout', 'dials-2.2'], workdir=workdir)) + self.add_step(self.shell(command=['git', 'checkout', 'dials-3.2'], workdir=workdir)) self.add_step(self.shell( - command=['git', 'branch', '--set-upstream-to=origin/dials-2.2', 'dials-2.2'], + command=['git', 'branch', '--set-upstream-to=origin/dials-3.2', 'dials-3.2'], workdir=workdir)) I was wondering - what are the constraints in PHENIX builds which mean bouncing around between extremely different DIALS releases is necessary? I note the shift from 2.2 to 3.2 would give a significant change in behaviour to the end user (who ultimately we may end up having to help with debugging) If we knew better why these changes were coming through, maybe we could help to keep PHENIX up to date? I would draw comparisons with CCP4 however they have been stuck in 2.2-series forever now as they’re still not able to support Python3 - will be in CCP4 8.x which will be ready any time now. I only mention this as it would be really good to start eliminating obsolete versions from distribution as “please go to dials.github.io and install a non-ancient version” is annoying advice to an end user with a fresh install of PHENIX or CCP4.

Is there a schedule for the python3 migration or can cctbx.python already be built to be/use a python3 interpreter?
by Jan M. Simons 12 Jul '21

Cheers, I'm getting more and more concerned with the state of cctbx and the impending removal of python2 from quite a lot of major linux distributions in the near future. So far I have not managed to find documentation on how to build the cctbx to then use a python3 interpreter for the cctbx.python script, but I would really like to have this, as I'd have to check/port my code that's using cctbx modules (mostly smtbx and xrax) to python3 as well, so that it does not get obsoleted. So is it possible to build cctbx as a python3 module by now and if so how would one be able to do this? Thanks for your support Jan
