Jussi Saurio	f2079d8f07	test/fuzz: improve error handling in tx isolation fuzz test ... - extract out common behavior for checking acceptable errors - add functionality to check which errors require rolling back a transaction	2025-09-15 08:03:08 +03:00
Jussi Saurio	1c5febf047	test/fuzz: introduce fuzzoptions to tx isolation test ... this makes it significantly easier to tweak the tx isolation test parameters, and also makes it much easier to run the MVCC version of the test without manually tweaking code inline to make it work. introduces default options for the non-mvcc and mvcc test variants.	2025-09-15 07:44:16 +03:00
Pekka Enberg	24c50597ad	Merge 'Random fixes for MVCC' from Jussi Saurio ... based on #3110 closes #3111 closes #3113 closes #3114 all discovered using `test_multiple_connections_fuzz_mvcc`, so no separate tests. i can add regression unit/integration tests tomorrow mvcc: properly remove mutations of rolled back tx mvstore was not removing deletions made by a tx that rolled back. deletions are removed by clearing the `end` mark from the row version. --- mvcc: properly clear tx states when mvcc tx rolls back --- mvcc: don't double-rollback on write-write-conflict handle_program_error() already rolls back if this error happens. double rollback causes a crash. Closes #3115	2025-09-15 07:39:35 +03:00

Jussi Saurio	7fe25a1d0e	mvcc: remove conn.mv_transactions ... afaict this isn't needed for anything since there is already conn.mv_tx_id	2025-09-14 21:26:58 +03:00
Jussi Saurio	5feb9ea2f0	mvcc: fix non-concurrent transaction semantics ... on the main branch, mvcc allows concurrent inserts from multiple txns even without BEGIN CONCURRENT, and then always hangs whenever one of the txns tries to commit. this commit fixes that issue.	2025-09-14 21:23:06 +03:00
