When being used by the compiler, fix up types2 error messages to be more
like Go 1.17 compiler errors. In particular:
- add information about which method is missing when a type is not
assignable/convertible/etc. to an interface.
- add information about any existing method which has the same name,
but wrong type.
- add extra hint in the case that the source or destination type is a
pointer to an interface, rather than an interface.
- add extra hint "need type assertion" in the case that the source is
an interface that is implemented by the destination.
- the following change in the CL stack also adds information about any
existing method with a different name that only differs in case.
Include much of the new logic in a new common function
(*Checker).missingMethodReason().
types2 still adds a little more information in some cases then the Go
1.17 compiler. For example, it typically says "(value of type T)",
rather than "(type T)", where "value" could also be "constant",
"variable", etc.
I kept the types2 error messages almost all the same when types2 is not
used by the compiler. The only change (to reduce amount of compatibility
code) was to change "M method" phrasing in one case to "method M"
phrasing in one error message (which is the phrasing it uses in all
other cases). That is the reason that there are a few small changes in
types2/testdata/check/*.src.
Added new test test/fixedbugs/issue48471.go to test that the added
information is appearing correctly.
Also adjusted the pattern matching in a bunch of other
test/fixedbugs/*.go, now that types2 is producing error messages closer
to Go 1.17. Was able to remove a couple test files from the types2
exception list in run.go.
Updated #48471

If an interface contains a blank method, that's already an error. No
need for useless follow-up error messages about not implementing them.
Fixes #42964.

With this CL, the first ~500 errorcheck tests pass when running
go run run.go -v -G
in the $GOROOT/test directory (the log output includes a few dozen
tests that are currently skipped).

This change adds line position tests for several yyerror calls in the
typechecker that are currently not tested in any way.
Untested yyerror calls were found by replacing them with
yerrorl(src.NoXPos, ...)
(thus destroying position information in the error), and then running
the test suite. No failures means no test coverage for the relevant
yyerror call.

// ERROR "pattern1" "pattern2"
means that there has to be one or more
lines matching pattern1 and then excluding
those, there have to be one or more lines
matching pattern2. So if you expect two
different error messages from a particular
line, writing two separate patterns checks
that both errors are produced.
Also, errchk now flags lines that produce
more errors than expected. Before, as long as
at least one error matched the pattern, all the
others were ignored.
Revise tests to expect or silence these
additional errors.
