[Issue 9949] New: MDB_RDONLY txn segfaults on newly created database
by openldap-its＠openldap.org 14 Nov '22

https://bugs.openldap.org/show_bug.cgi?id=9949 Issue ID: 9949 Summary: MDB_RDONLY txn segfaults on newly created database Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: jeffrey.reynolds(a)ticketmaster.com Target Milestone: --- The very simple code will cause a seg fault. ``` auto env = create_env("env_name"); // creates the environment. not included here because this part is in rust // it will open or create the database. i don't think the problem lies in here. MDB_txn* txn{}; mdb_txn_begin(*env, nullptr, MDB_RDONLY, &txn); MDB_dbi dbi{}; mdb_dbi_open(txn, "db_name", MDB_CREATE, &dbi); ``` This segfaults on `liblmdb/mdb.c:11050`. Specifically `tracked->mc_next = *tp;` However, the problem isn't in mdb_dbi_open, it is failing because mt_cursors is never initialized. A small change ` mdb_txn_begin(*env, nullptr, 0, &txn);` and mt_cursors will be initialized with the default env->me_txn0, that has a properly initialized mt_cursors, per this line `liblmdb/mdb.c:5581`, `txn->mt_cursors = (MDB_cursor **)(txn->mt_dbs + env->me_maxdbs);` for the MDB_RDONLY transaction, it looks like it will initialize mt_cursors _if_ it happens to have a parent, `liblmdb/mdb.c:3178`, but otherwise it leaves it uninitialized. Is this a bug, or do have i have to a parent to start a readonly transaction on a new database? -- You are receiving this mail because: You are on the CC list for the issue.
