From 3726d91d680b20d147f5b0b6222232d10930d121 Mon Sep 17 00:00:00 2001 From: "Bryan C. Mills" Date: Thu, 21 Feb 2019 12:00:12 -0500 Subject: [PATCH] cmd/go/internal/imports: use the full path to resolve symlinks info.Name returns a name relative to the directory, so we need to prefix that directory in the Stat call. (This was missed in CL 141097 due to the fact that the test only happened to check symlinks in the current directory.) This allows the misc/ tests to work in module mode on platforms that support symlinks.
