fix(#42): directory content-subspace prefix double-prepended - #77
Merged
Conversation
5 tasks
The prefix stored in a directory node already includes the content subspace key (composed in createInternal as contentSubspace->key() . allocatedPrefix). But contentsOfNode(), createInternal(), and removeInternal() prepended the content subspace key again when constructing the returned DirectorySubspace or clearing content keys. For the default (empty) content subspace this was harmless. Inside a partition (non-empty content subspace) it produced a doubled prefix (P + P + key instead of P + key), landing directories at the wrong location and breaking cross-binding interop. The partition branch already passed $prefix directly; this fix aligns the non-partition branch to match. Closes #42

Changes
src/Directory/DirectoryLayer.php: Removed the redundantcontentSubspace->key()prepend incontentsOfNode(),createInternal(), andremoveInternal()— the stored prefix is now used directly, matching the existing partition branch behavior.Tests
tests/Unit/DirectoryDoublePrefixTest.php): 3 tests coveringcontentsOfNode()with empty content subspace, non-empty content subspace, and partition layertests/Integration/DirectoryTest.php): 4 tests covering directory creation inside a partition (single prefix, round-trip, key write/read, and top-level directory prefix)
