fix(sql): read DDL routine references from the file, not the recovered parse - #3447
Unit Tests fail on main in every leg (run 40145807619): 12 tests in test_sql_ddl_routine_references.py, every DDL clause case plus test_an_aggregate_counts_its_state_function_once_per_statement, find no CALLS edge.
The statement-isolated SQL parse (#3180, merged in #3254) blanks each statement that fails to parse on its own, and tree-sitter-sql fails on CREATE AGGREGATE, CAST, OPERATOR, EVENT TRIGGER, FOREIGN DATA WRAPPER and LANGUAGE. The DDL scan for routine references (#3181, merged in #3251) read the recovered tree's text, so once a file needed recovery those clauses were gone and their routines lost every caller. Each PR passed against the main it was tested on.
Fix
CallProcessor._sql_source_text reads the file being walked and cuts the root's byte span from it. The recovered copy blanks statements in place and keeps every offset, so the span covers the same text as written. It falls back to the tree's own text when no file is being walked, when the file can no longer be read, or when the file is shorter than the tree's span.
Testing
Red. On main at e790ff5, test_sql_ddl_routine_references.py reports 12 failed, 13 passed, the same 12 as CI.
Green. With the fix, the file passes in full, including the two new tests:
test_ddl_a_statement_isolated_parse_blanks_still_references_its_routine checks that the recovered tree has lost the EVENT TRIGGER text and that the routine still gets its caller and site.
test_the_ddl_scan_reads_the_tree_when_the_file_cannot_stand_in_for_it is the negative test. With no file, a missing file, or a truncated file, the scan reads the tree's text instead of raising or cutting a short file. There is one case per fallback.
Mutations, one at a time:
Mutation
Red
The scan reads root_node.text again
the 12 tests that fail on main, plus test_ddl_a_statement_isolated_parse_blanks_still_references_its_routine
No-file guard removed
[no-file-being-walked] only
OSError re-raised instead of falling back
[file-gone] only
Short-file guard removed
[file-shorter-than-its-tree] only
The full file passes (29) before the mutations, and the source is restored byte for byte after each one.
Summary by CodeRabbit
Bug Fixes
Improved detection of routine references in SQL DDL, including cases where an event trigger is omitted during parsing.
Improved reliability when reading SQL source for reference analysis. If the source file is unavailable, unreadable, or shorter than expected, the parser’s available text is used instead. This helps preserve reference results across incomplete or inaccessible source files.
Tests
Added regression coverage for event trigger references and source-reading fallback scenarios.
…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.
_sql_source_text falls back to the tree's text when no file is being
walked, when the file can no longer be read, and when it is shorter than
the tree's span. None of the three had a test, so SonarCloud measured
69.2% coverage on the new code (gate: 80%). Each case now runs the
fallback, and removing any one of them fails exactly that case.
SQL DDL reference scanning now reads and normalizes current file bytes, slices them to the syntax tree root span, and falls back to tree text when file access or span coverage is unavailable. Regression tests cover recovered EVENT TRIGGER references and fallback cases.
Changes: SQL DDL source text recovery
Layer / File(s)
Summary
Source text recovery and regression coverage codebase_rag/parsers/call_processor.py, codebase_rag/tests/test_sql_ddl_routine_references.py
The DDL scan uses normalized source bytes within the root node’s span, with root_node.text as fallback when the file is unavailable or too short. Tests cover an EVENT TRIGGER caller edge and fallback cases.
An edit during indexing can produce incorrect SQL routine references. Keep the parsed source with the AST before merging, unless this inconsistency is explicitly accepted.

Keep DDL scanning on the parsed source snapshot
If a SQL file is edited after the initial hash/read but before the call-processing pass, this rereads the newer on-disk contents while the AST, definitions, and cached hash were built from the earlier changed_entries byte snapshot. When the replacement remains at least root_node.end_byte bytes long, the length guard accepts it, so the run can publish DDL edges and source locations from a different revision than the graph's definitions. Pass the original source snapshot through to this scan, or verify that the reread still matches the parsed revision before using it.

Keep the parsed SQL source with the AST.
pre_parsed can provide a root built from supplied file_bytes, but _sql_source_text rereads _call_file. If the file changes to another source with the same or greater normalized length before the call walk, the check still passes. The DDL scanner then records a CALLS edge for the replacement routine, not the routine in the parsed source.
Retain and pass the normalized parser bytes with the root, then slice those bytes instead of rereading _call_file.

…d parse
Port of #3447 so this PR's CI runs against a main that passes: the
statement-isolated SQL parse (#3254) blanks each statement that fails
on its own, which is most of the DDL the routine-reference scan (#3251)
reads, so main fails 12 tests in test_sql_ddl_routine_references.py.
The change is identical to #3447 and becomes a no-op once it merges.

Main's #3448 fixes the SQL DDL scan by keeping the parsed source
bytes, superseding the port of #3447 carried here; both SQL files take
main's version, so this branch no longer changes them.
