Go command GONOSUMDB wildcard checksum database go.sum behavior official documentation

💡 Result:

In the Go programming language, the GONOSUMDB environment variable is used to define a list of module path prefixes that should be excluded from checksum database verification [1][2]. When a module's path matches a pattern listed in GONOSUMDB, the go command skips querying the checksum database for that module [3][4]. Key behaviors regarding GONOSUMDB and wildcards: 1. Pattern Matching: The GONOSUMDB variable accepts a comma-separated list of glob patterns [1][2]. The matching logic follows the syntax of Go's path.Match function [1]. 2. Skipping Database Lookups: If a module path matches a pattern in the list, the go command treats it as exempt from checksum database verification [3][5]. Instead of relying on the checksum database, the go command calculates the checksum locally from the downloaded source and records it in the go.sum file [6]. 3. Security Purpose: This mechanism is primarily designed to prevent private module paths from being sent to public checksum databases (such as sum.golang.org), which would otherwise leak potentially sensitive import paths [2][7]. 4. Configuration: You can set multiple patterns using commas, for example: GONOSUMDB="github.com/mycompany/,example.com/private/" [2][8]. 5. Precedence: When a module is excluded via GONOSUMDB, the go command does not stop the build, but it assumes responsibility for verifying the module's integrity locally [6]. If a module is not excluded and the checksum database cannot verify it, the build will fail [2][6]. For more information, you can refer to the official Go documentation on private modules and the Go module reference [9][1].

Do not disable checksum-database verification for all modules.

GONOSUMDB="*" makes go mod download skip the public checksum database for every module. Scope GONOSUMDB to private module-path prefixes, if required, so public modules retain checksum-database verification.

In
`@ci-operator/config/openshift-eng/openshift-logging-e2e-tests/openshift-eng-openshift-logging-e2e-tests-main.yaml`
at line 10, Update the go mod download command in the main test configuration to
remove the global GONOSUMDB="*" setting; if private modules require bypassing
checksum verification, scope GONOSUMDB only to their specific module-path
prefixes while preserving public module checksum-database verification.
