[Issue 10518] New: Every write transaction leaks a mutex on Windows
by openldap-its＠openldap.org 30 Jun '26

https://bugs.openldap.org/show_bug.cgi?id=10518 Issue ID: 10518 Summary: Every write transaction leaks a mutex on Windows Product: LMDB Version: unspecified Hardware: x86_64 OS: Windows Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: bhargavabhat(a)gmail.com Target Milestone: --- Created attachment 1152 --> https://bugs.openldap.org/attachment.cgi?id=1152&action=edit Create and use the mutex for the duration of the env I see that on master3 branch, every write transaction leaks a mutex. LMDB creates a new mutex on every non-read-only transaction in `mdb_txn_renew0`. In `mdb_txn_end`, when the write transaction finishes, it sets `mode` to 0 and unlocks it. ``` if (!txn->mt_parent) { env->me_txn = NULL; mode = 0; if (env->me_txns) UNLOCK_MUTEX(env->me_wmutex); } ``` Later, it does this. ``` if (mode & MDB_END_FREE) { if (!F_ISSET(txn->mt_flags, MDB_TXN_RDONLY)) pthread_mutex_destroy(&txn->mt_child_mutex); // never reached free(txn); } ``` So we just don't close the mutex. It's probably not a big deal on non-Windows platforms, but on Windows, the number of handles owned by the process keeps increasing which limits the total number of write transactions we can do in the lifetime of the process. I didn't really understand why we need to create a mutex on every non-read-only transaction. Can we just tie the lifetime of the mutex to the environment instead of the transaction? I'm attaching a patch which tries to fix it. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9496] New: Some writes missing from database
by openldap-its＠openldap.org 30 Jun '26

https://bugs.openldap.org/show_bug.cgi?id=9496 Issue ID: 9496 Summary: Some writes missing from database Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: igfoo(a)github.com Target Milestone: --- With the attached test program, some of my database writes appear not to actually be written to the database. For example, a run may look like this: $ ./run.sh All done. All finished 1802 test.txt foo_200 is missing bar_200 is missing foo_404 is missing bar_404 is missing foo_407 is missing bar_407 is missing The script that I am using to run the program is below. This is using mdb.master 52bc29ee2efccf09c650598635cd42a50b6ecffe on Linux, with an ext4 filesystem. Is this an LMDB bug, or is there a bug in my code? Thanks Ian #!/bin/sh set -e if !
