fix(incremental): keep Go result types and package clauses of unchanged files - #3281
Conversation
…ed files On Go's tree-sitter path (every `_test.go`, and any module go/types cannot load), `b, _ := NewBox(2)` types `b` from `go_function_return_types`, `MakeBox(2).Size()` and `b.Self().Size()` chain through `method_return_types`, and the chain's struct lookup checks same-package visibility through `go_package_names`. All three were filled only while the defining file was parsed, so an incremental run that re-parsed the caller alone left them empty for unchanged files and `b.Size()` bound `heuristic` to another type's `Size` (#3272; gin: 279 context_test call keys flipped). Go Functions and Methods now store `first_return_type` and `chain_return_type`, computed by the same extractors ingest records with, and a Go Module stores its `go_package`. Rehydration reads them back for definitions and modules the run does not parse; the eval double returns them, and the graph schema documents them.

`go_package`, `first_return_type` and `chain_return_type` are read back only by an incremental run's rehydration; a graph round-tripped through protobuf behaves as every run did before, until the file is next parsed.

Explanation
The PR meets the coding requirements in [
#3272]. Go functions persistfirst_return_typeandchain_return_type. Go methods persistchain_return_type. Go modules persistgo_package. Rehydration restores these values for unchanged definitions and modules. Re-parsed definitions retain values recorded during the current parse. The regression tests cover result assignments, named results, function chains, method chains, package visibility, and changed helper results.

Parsing records a Go method's chained result under its natural qn, which every build file declaring the method again shares, the last one in registration order standing. Reading each node's stored result back under its own qn left the natural key with the first file's result, so a chain through it typed another receiver than a clean index does. The rows are now replayed in registration order under the natural qn, as for Rust.

Main's Module.php_namespace (#3297) met the PR's Module.go_package in the constants, Module schema, CYPHER_ALL_MODULE_QNS, module node props, module rehydration, the eval ingestor and the parity test: kept both properties; graph-schema.md regenerated. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013MgsnsA3jM14E4ai22xnhy
Main's #3237 (issue #3206) exported most node properties to protobuf and cut _NOT_EXPORTED down to call-specific and rehydration-only ones. The parity test conflicted on Module, Function and Method: took main's sets and kept this PR's go_package, first_return_type and chain_return_type in them, since they are read back only by rehydration and degrade the same safe way as php_namespace and the C# extension properties.

…d parse The statement-isolated SQL parse (#3180) blanks each statement that fails on its own, and tree-sitter-sql fails on CREATE AGGREGATE, CAST, OPERATOR, EVENT TRIGGER, FOREIGN DATA WRAPPER and LANGUAGE. The DDL scan (#3181) read the recovered tree's text, so once a file needed recovery those clauses were gone and their routines lost every CALLS edge. Each branch passed alone; on main, 12 tests in test_sql_ddl_routine_references.py fail. The scan now cuts the root's span from the file as written, which the recovered copy keeps byte for byte.

The fix is already in #3439 (2f58011: read the DDL from the file as written). I ported that same change here as 3b88144, on top of a merge of current main (91f61b7). It becomes a no-op once main carries it. Locally the file went from 12 failed to 26 passed. The full unit suite has no other failures except four toolchain tests that also fail on main in this container (it has no dotnet and Go 1.24). Generated by Claude Code |
