Timothy Flynn	4e974e6d60	LibSQL: Rename expression tree depth limit test case ... Meant to rename this before committing the test - 'stack_limit' isn't a great name when there's multiple test cases for various stack overflows.	2021-06-08 19:08:13 +02:00
Timothy Flynn	f8f36effc9	LibSQL: Limit the allowed depth of an expression tree ... According to the definition at https://sqlite.org/lang_expr.html, SQL expressions could be infinitely deep. For practicality, SQLite enforces a maxiumum expression tree depth of 1000. Apply the same limit in LibSQL to avoid stack overflow in the expression parser. Fixes https://crbug.com/oss-fuzz/34859.	2021-06-05 23:48:18 +04:30
Timothy Flynn	a870eac0eb	LibSQL: Report a syntax error for unsupported LIMIT clause syntax ... Rather than aborting when a LIMIT clause of the form 'LIMIT expr, expr' is encountered, fail the parser with a syntax error. This will be nicer for the user and fixes the following fuzzer bug: https://crbug.com/oss-fuzz/34837	2021-06-03 08:30:13 +02:00
Timothy Flynn	ab79599a5e	LibSQL: Return an error for empty common table expression lists ... SQL::CommonTableExpressionList is required to be non-empty. Return an error if zero common table expressions were parsed. Fixes #7627	2021-06-01 23:48:21 +04:30
