=== Unsafe Configuration Resolution Errors

Resolving a configuration can have side effects on Gradle's project model.
As a result, Gradle must manage access to each project's configurations.
There are a number of ways a configuration might be resolved unsafely.
For example:

	// Create adds a new configuration object to the store. If an object with the
	// same name and namespace for the type already exists, the operation fails
	// with no side effects.
	Create(config config.Config) (revision string, err error)

	// Update modifies an existing configuration object in the store.  Update
	// requires that the object has been created.  Resource version prevents

func appendWalkStmt(init *ir.Nodes, stmt ir.Node) {
	op := stmt.Op()
	n := typecheck.Stmt(stmt)
	if op == ir.OAS || op == ir.OAS2 {
		// If the assignment has side effects, walkExpr will append them
		// directly to init for us, while walkStmt will wrap it in an OBLOCK.
		// We need to append them directly.
		// TODO(rsc): Clean this up.
		n = walkExpr(n, init)
	} else {

// The op built by this builder is stateful if its behavior depends on some
// state beyond its input tensors (e.g. variable reading op) or if it has a
// side-effect (e.g. printing or asserting ops). Equivalently, stateless ops
// must always produce the same output for the same input and have no
// side-effects.
//
// By default Ops may be moved between devices. Stateful ops should either not

	// input bit i affects output bit j.
	grid := make([][hashSize]int, n)

	for z := 0; z < REP; z++ {
		// pick a random key, hash it
		k.random(r)
		h := k.hash()

		// flip each bit, hash & compare the results
		for i := 0; i < n; i++ {
			k.flipBit(i)
			d := h ^ k.hash()
			k.flipBit(i)

			// record the effects of that bit flip
			g := &grid[i]

	}
	attrs := uint32(syscall.FILE_FLAG_BACKUP_SEMANTICS)
	// Use FILE_FLAG_OPEN_REPARSE_POINT, otherwise CreateFile will follow symlink.
	// See https://docs.microsoft.com/en-us/windows/desktop/FileIO/symbolic-link-effects-on-file-systems-functions#createfile-and-createfiletransacted
	attrs |= syscall.FILE_FLAG_OPEN_REPARSE_POINT
	h, err := syscall.CreateFile(p, 0, 0, nil, syscall.OPEN_EXISTING, attrs, 0)
	if err != nil {
		return 0, err

In some cases even well-trusted tools can produce non-repeatable outputs, and lead to cascading effects.
One example is Oracle's Java compiler, which, https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8067422[due to a bug], was producing different bytecode depending on the order source files to be compiled were presented to it.

		// If the signature doesn't use its type parameters, subst
		// will not make a copy. In that case, make a copy now (so
		// we can set tparams to nil w/o causing side-effects).
		if sig == orig {
			copy := *sig
			sig = &copy
		}
		// After instantiating a generic signature, it is not generic
		// anymore; we need to set tparams to nil.
		sig.tparams = nil
		res = sig

	CRnGT represents CR bit 1 of CR field n. (0-7)
	CRnEQ represents CR bit 2 of CR field n. (0-7)
	CRnSO represents CR bit 3 of CR field n. (0-7)
