There were several issues with the error test case that have been
addressed in this commit.
- It is possible to specify a whitelist of calls that error handling
should be ignored for.
- Additional support for ast.ExprStmt for cases where the error is
implicitly ignored.
There were several other additions to the helpers and call list in order
to support this type of functionality.
Fixes#54
- Update call list to work directly with call expression
- Add call list test cases
- Extend helpers to add GetCallInfo to resolve call name and package or
type if it's a var.
- Add test cases to ensure correct behaviour
There seems to be an inconsistency in the way that the type.Info.Uses
map is populated by the type checker in Go 1.5 and the latest release.
It is possible to ascertain the package that relates to an object 1.7.x
release but this does not work for earlier Go versions.
To work around this limitation we now track imports, and monitor if they
are aliased or initalization only imports.
This introduces a helper function that will significantly reduce the
number of false positives that occur due to the use of regexp based
call matching.
It resolves the object related to a CallExpr and checks that against the
supplied package and identifier name. If both of these match the
returned value is the CallExpr and Object.
