Packages above empty newline are considered to be part of SDK (14) and packages below (5) are considered "special cases" I paid no further attention to in the rest of this report.

Detailed report (which provider imports what package) is in report-provider-imports.csv.

Dependencies

Each of these 14 SDK packages listed above has its own dependency tree within Terraform and outside of it. Go stdlib dependencies are omitted.

These are just direct imports, not transitive dependencies.

Package exposure

Which parts of each package are actually in use by providers?

Methodology

Assuming all providers are cloned into $GOPATH/src/github.com/terraform-providers/:

Create report of all uses of a package

For package helper/schema as below:

for f in $GOPATH/src/github.com/terraform-providers/*; do ./list-package-refs.sh $f github.com/hashicorp/terraform/helper/schema; done > report-exposure-helper-schema.txt

Count by exported name

For package helper/schema as below, assuming report-exposure-helper-schema.txt has been created:

awk -F ":" '{a[$2]++}END{for(i in a)  print a[i],i}' report-exposure-helper-schema.txt | sort -r -g
