Zach, Eric, Tom

Greg on vacation

July 11, 2022

= Agenda =

== General ==

== ChimeraX ==
=== General ===
1) Pull vs Rebase Strategy
  - Zach suggests {{{echo "[pull]\n\trebase = true" >> .git/config}}}

2) 1.5 Roadmap

=== Build System ===
1) Supporting IDEs
  - may only need editable installs (will require workaround as namespace packages cannot be installed in this mode automatically)
  - editable installs should also let us call ChimeraX with Python for rapid iteration and the C launcher for detailed crash info
  - Zach mentioned PyCharm, LSP (Language Server Protocol), XCode
  - Greg mentioned Visual Studio 

2) API for getting C headers: get_include (see: numpy.get_include)
  - {{{native-packaging}}} moves bundle header and source files to {{{bundle/src/include/module}}} \
  - maybe just use header files?

3) API for getting library directories: get_libdir

4) macOS compiler call in Makefiles

=== Infrastructure ===
1) Beta releases on Toolshed

2) Decoupling core bundle version number from the ChimeraX release number

3) Prereq audit after 27 June 

4) arm64 port

== Chimera ==
1) Back up the build machine to a solid state drive

--------------------------
= Discussion =

* Linux build failures
  - Only the generic Linux daily build is on the download page.
  - Not clear what is going wrong, daily.out shows failure to import chimerax running cxtestimports
  - Eric see copy command (cp) errors in daily build email 
  - Will let Greg look into this

* Git rebase
  - Zach suggests having git pull use rebase to avoid have our commits being merges.
  - Tom hasn't found the merge commits to cause any problem.
  - Eric asks about his local branches if rebase would keep trying to reapply all his local commits.  Seems yes.  That would be troublesome with long-lived branches causing merge conflicts.

* Update prereqs
  - Eric updated some prereqs last week
  - Tom plans to update ones related to volumes (numpy...)

* Developer meeting every Monday 2 pm unless cancelled in advance.

--------------------------
