Background

It is somewhat hilarious that the diff for this pull request is so small. There are no changes in 10gen/compass to review really. All of the work took place in hadron-build, Compass' build and release toolchain. It was a brutal amount of work as testing changes required approximately 25 minutes of cycle time and in the push to get it done, required a week of 8:00am - 10:00pm work days.

I solved several unanticipated challenges with non-standard methods so I'd like to take a chance to document them for the sake of the rest of the team.

Problem 1: Secure, Stable Keychain Access

• keytar: the electron community's module of choice for secure credential storage
• node.js native add-on: requires -dev|devel system packages to compile
• keytar Linux backend uses gnome-keyring
• gnome-keyring
• Tracked down PR on upstream that was close enough
• 💡 gnome-keyring ➡️ libsecret = 🏆

Problem 2: Evergreen

• Can't add packages on evergreen
• 💡 prebuild + keytar = 🏆

Problem 3: Travis

• But now all tests timeout on Travis
• prebuild's of keytar on different ubuntu version
• travis.yml dist: trusty: ubuntu server 12.04 ➡️ 14.04 = 🏆

Problem 4: Evergreen Again

• redhat.mongodb.parts 7.2 workstation in aws
  • works after yum install libsecret
  • build keytar from source works
• Using prebuild on rhel evergreen fails
• rhel server 7.0 on evergreen
  • libsecret-1.so can't be found
  • rpm try/fail....
• 💡
  • prebuild fails only because libsecret-1.so is not there at build time
  • will be as rpm/deb dependency on libsecret dependency
  • Upload 7.2 .so to github ➡️ evergreen wget if rhel= 🏆

Why spend time on Linux?

• Compass is a replacement for the MongoDB shell, so why Linux? They like shells right?
• Linux ➡️ Red Hat ➡️ CentOS (Scientific Linux) = What Daniel used at Schrodinger
• CentOS what sci phd programs tell students to install
• They grow accustomed and use in professional work after dissertation
