fix(extract): indexing large SQL files crashes native parser (tree-sitter SQL assertion / stack overflow)

[lg320531124]

Bug

Indexing a repository that contains large SQL files (e.g. schema dumps >10K lines, stored procedures) causes the native parser to crash with either:

• A tree-sitter SQL assertion failure
• A stack overflow in the C parser

This crashes the entire indexing pipeline rather than gracefully degrading for that file.

Expected behavior

• Large SQL files that exceed the parser's capacity should be skipped with a warning, not crash the pipeline.
• Alternatively, increase the stack size for the SQL tree-sitter grammar or add a file-size/line-count guard before parsing.

Suggested fix

Add a pre-parse guard in the extraction pipeline:

if (line_count > MAX_SQL_PARSE_LINES) {
    log_warn("skipping large SQL file: %s (%d lines)", path, line_count);
    return SKIP;
}

Thanks for raising this! It looks like a duplicate of an existing issue — the canonical one is linked above. Continuing the discussion there keeps everything in one place. We leave this open for visibility; a maintainer will close it once it's fully covered.

Thanks for splitting this out. This duplicates #668, which is the canonical large-SQL parser crash report. The corresponding fix path is being tracked through #698, so I am closing this duplicate to keep status in one place.
