vulncheck: remove isLocal check from fetchVulnerabilities isLocal check was added to improve efficiency by avoiding fetch of data that's not going to be used. Version info is inaccurate or unavailable for modules that are in writable local directories so vuln check for those modules are skipped anyway. With the check, fetchVulnerabilities excludes vulnerabilities for modules if their source files are outside the module cache. The location of the module cache was determined by querying GOMODCACHE and GOPATH environment variables of the govulncheck process. That worked well for govulncheck when it is used for source scanning. The logic was copied to vulncheck API internal. However, relying on process's GOMODCACHE/GOPATH environment variables limit the API's utility. For example, Gopls may use different GOMODCACHE/GOPATH for each workspace it's processing and they can be different from the Gopls's own GOMODCACHE/GOPATH env vars. Test data can be loaded with a fake GOMODCACHE that's different from the GOMODCACHE env var of the test process. There was an escape flag to skip this check to work with the test environment where the module cache and GOPATH are different from the test process's. But that is unexported; external packages cannot utilize it and that prevents writing tests from external packages. This CL proposes to remove the isLocal check. There is already a cache that reduces volume of data fetch over network, and vulncheck can potentially address the efficiency issue in different ways. Users and applications that need to exclude vulnerabilities of local modules, may utilize golang.org/x/vuln/client.Client and implement filtering from GetByModule. Or, if this problem is common, we may consider an explicit setting in the vulncheck.Config.

This repository contains code for hosting the Go Vulnerability Database. The actual reports can be found at x/vulndb.
Neither the code, nor the data, nor the existence of this repository is to be considered stable. See the Draft Design for details on this project.
The Go vulnerability database is rooted at
https://storage.googleapis.com/go-vulndb and provides data as JSON. We recommend using client.Client to read data from the Go vulnerability database.
Do not rely on the contents of the x/vulndb repository. The YAML files in that repository are maintained using an internal format that is subject to change without warning.
The endpoints the table below are supported. For each path:
|$base/index.json||List of module paths in the database mapped to its last modified timestamp (link).|
|$base/$module.json||List of vulnerability entries for that module (example).|
|$base/ID/index.json||List of all the vulnerability entries in the database|
|$base/ID/$vuln.json||An individual Go vulnerability report|
Note that these paths and format are provisional and likely to change until an approved proposal.
Some of these packages can probably be coalesced, but for now are easier to work on in a more segmented fashion.
