Package zip provides support for reading and writing ZIP archives.

See the [ZIP specification] for details.

This package does not support disk spanning.

A note about ZIP64:

To be backwards compatible the FileHeader has both 32 and 64 bit Size
fields. The 64 bit fields will always contain the correct value and
for normal archives both fields will be the same. For files requiring

 * <ul>
 * <li>the unreleased <b>staged</b>, M.N-2.0 (N &gt; 2) on the `M.(N-2)` branch</li>
 * </ul>
 * <p>
 * Each build is only concerned with versions before it, as those are the ones that need to be tested
 * for backwards compatibility. We never look forward, and don't add forward facing version number to branches of previous
 * version.
 * <p>

== Testing backwards compatibility

Backwards compatibility tests exist to test upgrading from each supported version
to the current version. To run them all use:

-------------------------------------------------
./gradlew bwcTest

        // First byte should be length of "test" (4) after processing
        assertEquals(4, dst[0]);

        // After processing, dots should be replaced with length markers
        // The scope processing happens backwards
        assertEquals(name.scope.length() + 2, length);
    }

    @Test
    void readScopeWireFormat_withMultipleLabels_shouldParseCorrectly() {
        byte[] src = new byte[100];

			// It looks like this should allow listing any key that isn't "default-test-key", however
			// the policy engine matches all Deny statements first, without regard to Resources (for KMS).
			// This is for backwards compatibility where historically KMS statements ignored Resources.
			policy: `{
						"Effect": "Allow",
						"Action": ["kms:ListKeys"]
					},{
						"Effect": "Deny",
						"Action": ["kms:ListKeys"],

      // Both a and b are odd. Assume a > b; then gcd(a - b, b) = gcd(a, b).
      // But in gcd(a - b, b), a - b is even and b is odd, so we can divide out powers of two.

      // We bend over backwards to avoid branching, adapting a technique from
      // http://graphics.stanford.edu/~seander/bithacks.html#IntegerMinOrMax

      int delta = a - b; // can't overflow, since a and b are nonnegative
