version

Documentation

Overview

Package version provides information about FerretDB version and build configuration.

Required files

The following generated text files may be present in this (build/version) directory during building:

• version.txt (required) contains information about the FerretDB version in a format similar to `git describe` output: `v<major>.<minor>.<patch>`.
• commit.txt (optional) contains information about the source git commit.
• branch.txt (optional) contains information about the source git branch.
• package.txt (optional) contains package type (e.g. "deb", "rpm", "docker", etc).

Go build tags

The following Go build tags (also known as build constraints) affect all builds of FerretDB, including embedded usage:

ferretdb_debug - enables debug build (see below; implied by builds with race detector)
ferretdb_hana  - enables Hana backend (alpha)
ferretdb_newpg - replaces PostgreSQL backend with a new version (alpha)

Debug builds

Debug builds of FerretDB behave differently in a few aspects:

• Some values that are normally randomized are fixed or less randomized to make debugging easier.
• Some internal errors cause crashes instead of being handled more gracefully.
• Stack traces are collected more liberally.
• Metrics are written to stderr on exit.
• The default logging level is set to debug.

Debug builds are orthogonal to production releases, development releases, and local/host builds. For example, the host build could be made non-debug, and the production release, in theory, could be a debug build.

Currently, our production releases are non-debug builds, and all other builds and releases (development releases, all-in-one releases, local builds, etc.) are debug builds.
