Notes

Permission issues with multiple EasyBuild users

• context: multiple EasyBuild users sharing an install target
• even with use of umask, permission issues on software/modules directory trees exist
• EasyBuild also fiddles with permissions, partially undoes permissions set based o umask
  • see use of adjust_permissions in post_install_step method in easyblock.py
  • parent directories of install dirs are created via make_dir method, which follows umask settings (?)
• dedicated issue opened for follow-up on this: https://github.com/hpcugent/easybuild-framework/issues/885

Tour of EasyBuild source code

• suggestion by Petar: short tour around EasyBuild framework source code by Kenneth
  • during a next conf call
• Kenneth: needs to be prepared well, next conf call might be difficult
  • around same time of release of EasyBuild v1.12, so busy times
  • week before one week off work for Kenneth, so likely crazy busy
• maybe even a dedicated conf call?

Problems with installing Python packages on SuSE systems

• install EasyBuild with EasyBuild on SLES failed
• --prefix using in setup.py install command is simply ignored
• installation target is somehow redefined to a system location, thus failing
• workaround is to put a .pydistutils.cfg file in $HOME specifying an empty prefix
• dedicated issue opened for follow-up on this: https://github.com/hpcugent/easybuild-easyblocks/issues/373
