## Architecture decision records (ADRs)

The Gradle team uses ADRs to record architectural decisions that the team has made.

See [Architecture decisions records](standards) for the list of ADRs.
Be aware these are very technical descriptions of the decisions, and you might find the documentation below more useful as an introduction to the internals of Gradle.

- **Reduce the size of the Gradle distribution** - We no longer need to carry multiple standard libraries for different languages.

## Decision

We do not introduce new public API methods that include Groovy types in their signatures.
Existing Groovy methods will not be removed immediately.

## Status

ACCEPTED

## Consequences

 * and the last 7 bits from this byte.

 * The end of the range is not encoded, but can be inferred by looking at the start of the range
 * that follows.

 * b1

 * This is either a mapping decision or the length of the mapped output, according to this table:

 *  0..63 : Length of the UTF-16 sequence that this range maps to. The offset is b2b3.

	_, isEncrypted := crypto.IsEncrypted(mi.UserDefined)

	// Read compression metadata preserved in the init multipart for the decision.
	_, isCompressed := mi.UserDefined[ReservedMetadataPrefix+"compression"]

This offered performance benefits that were too large to leave on the table, as well as opportunities to tune to our specific needs.

## Configuration protocol

Ztunnel, of course, needs to be dynamically configured in order to make decisions on how it should handle traffic.

// CheckPreconditionFn returns true if precondition check failed.
type CheckPreconditionFn func(o ObjectInfo) bool

// EvalMetadataFn validates input objInfo and GetObjectInfo error and returns an updated metadata and replication decision if any
type EvalMetadataFn func(o *ObjectInfo, gerr error) (ReplicateDecision, error)

// EvalRetentionBypassFn validates input objInfo and GetObjectInfo error and returns an error if retention bypass is not allowed.

   * one from the pool. We must take the pooled connection because by taking it from the pool, we've
   * fully acquired it.
   *
   * This test yields threads to force the decision of plan1 to be deliberate and not lucky. In
   * particular, we set up this sequence of events:
   *
   *  1. take plan 0
   *  3. plan 0 connects
   *  4. finish taking plan 1
   *
