…I V2." This reverts commit baa1786. The symlink resolution in this change is broken, as it does not take into account parent symlinks. Consider the following structure on the filesystem: a/d/file a/b/c/symlink -> ../../d/file And action inputs as follows: a/d/file (f -> a/b/c)/symlink -> ../../d/file with (f -> a/b/c) denoting that f is a symlink to directory c. This change then builds the following merkle tree: a d file f symlink -> ../../d/file My guesstimate is that there are a number of additional problems with this change and we should think hard about them when attempting to roll foward this change in the future. See for example Bazel's symlink resolution in FileFunction [1]. A real world example of this error is: bazelbuild#7212 Fixes bazelbuild#7212 [1] https://source.bazel.build/bazel/+/master:src/main/java/com/google/devtools/build/lib/skyframe/FileFunction.java;l=114?q=FileFunction
