Rene Cannao	178f679fad	fix: Handle optimizer hints /*+ */ correctly in query tokenizers ... The query tokenizers for both MySQL and PostgreSQL did not correctly handle optimizer hint comments in the format /*+ ... */. When parsing queries like `/*+ hostgroup=1000 */ SELECT 1`, the '+' character was incorrectly included in the extracted first comment content, resulting in the parsed key being '+hostgroup' instead of 'hostgroup'. This caused the query_processor_first_comment_parsing variable (modes 1 and 3) to not work correctly when using optimizer hint syntax. Changes: - c_tokenizer.cpp: Detect both /*! and /*+ comment formats - pgsql_tokenizer.cpp: Detect /*+ comment format - issue5384-t.cpp: Re-enable tests 2 and 3 (previously skipped) - pgsql-issue5384-t.cpp: Re-enable tests 2 and 3, add hostgroup 1000 setup Fixes #5413 (MySQL tokenizer) Fixes #5414 (PostgreSQL tokenizer)	1 month ago
Rene Cannao	ca73b9eced	Tokenizer: fix type mismatch for grouping limit variables ... Fixes issues #5396 and #5397. The variables mysql_thread___query_digests_grouping_limit and mysql_thread___query_digests_groups_grouping_limit (and their PgSQL counterparts) were incorrectly declared as bool instead of int in the tokenizer files. This caused any value greater than 0 to be treated as 1, effectively forcing a hardcoded grouping limit of 1 regardless of user configuration. By correcting the types to int, the tokenizer now correctly honors the configured values. Also added regression tests to regular_tokenizer_digests.hjson.	2 months ago
Rene Cannao	ca4f858b29	Fix uninitialized memory read in pgsql tokenizer ... Change malloc() to calloc() in get_result_buffer() to zero-initialize the query digest buffer before use. This prevents stage_2_parsing() from reading uninitialized memory when processing query digests. Fixes #5375	2 months ago
