// This tests to make sure that modules with symlinked circular dependencies
|
|
// do not blow out the module cache and recurse forever. See issue
|
|
// https://github.com/nodejs/node/pull/5950 for context. PR #5950 attempted
|
|
// to solve a problem with symlinked peer dependencies by caching using the
|
|
// symlink path. Unfortunately, that breaks the case tested in this module
|
|
// because each symlinked module, despite pointing to the same code on disk,
|
|
// is loaded and cached as a separate module instance, which blows up the
|
|
// cache and leads to a recursion bug.
|
|
|
|
// This test should pass in Node.js v4 and v5. It should pass in Node.js v6
|
|
// after https://github.com/nodejs/node/pull/5950 has been reverted.
