Sentry crash reports for Determinate Nix

As of version 3.18.0, Determinate Nix now uploads crash reports to Sentry, the industry-leading application monitoring platform that we at Determinate Systems also use for FlakeHub. We’re committed to relentlessly improving Determinate Nix, and proactive crash reporting is the next logical step in our efforts will enable us to more easily triage and remedy crashes that occur in the wild, without depending on manual use reports.

These crash reports contain this information (when applicable):

• The Determinate Nix version
• The Nix command that was run
• Crashpad information for crashes like segfaults and aborts
• Stack traces
• Standard context clues, like the operating system name and version, system architecture, and hostname

Crash reports do not contain things like these:

• Usernames
• IP addresses
• Performance traces
• Nix expressions
• Source code
• File paths

We’ve tried out these crash reports with a few Determinate Systems customers and they’ve already enabled us to squash several smaller bugs that otherwise may have gone undetected. We’re now ready to roll this out to all Determinate Nix users and fully confident that this new information-gathering process will yield clear benefits over time.
