[Issue 9278] New: liblmdb: robust mutexes should not be unmapped
by openldap-its＠openldap.org 15 Apr '26

https://bugs.openldap.org/show_bug.cgi?id=9278 Issue ID: 9278 Summary: liblmdb: robust mutexes should not be unmapped Product: LMDB Version: unspecified Hardware: All OS: FreeBSD Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: delphij(a)freebsd.org Target Milestone: --- Created attachment 736 --> https://bugs.openldap.org/attachment.cgi?id=736&action=edit A possible workaround We recently noticed that lmdb would have the memory region containing the robust mutex unmapped on mdb_env_close0(): munmap((void *)env->me_txns, (env->me_maxreaders-1)*sizeof(MDB_reader)+sizeof(MDB_txninfo)); Note that if this is the last unmap for a robust mutex, the FreeBSD implementation would garbage-collect the mutex, making it no longer visible to other processes. As the result, a second instance of the attached test.c (from https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244493 with minor changes) would trigger the assertion at mdb_txn_begin() because the acquisition of the mutex would return 22 (EINVAL), because the mutex appeared to be a robust mutex, but was invalid. The attached lmdb.diff is a possible workaround for this (it would skip unmapping when setting up the robust mutex for the first time). -- You are receiving this mail because: You are on the CC list for the issue.

https://bugs.openldap.org/show_bug.cgi?id=10180 Issue ID: 10180 Summary: mdb.c:2185: Assertion 'rc == 0' failed in mdb_page_dirty() Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: dominik(a)greysector.net Target Milestone: --- I'm experiencing a SIGABRT-induced crash in nheko, which uses lmdb for its database (~/.local/share/nheko/nheko/#hash#/{data,lock}.mdb). The assertion triggering the SIGABRT seems to be happening here: https://git.openldap.org/openldap/openldap/-/blob/master/libraries/liblmdb/… The crash happens on every nheko startup since yesterday, so I assume something added to the database is triggering it.

[Issue 9378] New: Crash in mdb_put() / mdb_page_dirty()
by openldap-its＠openldap.org 15 Apr '26

15 Apr '26

https://bugs.openldap.org/show_bug.cgi?id=9378 Issue ID: 9378 Summary: Crash in mdb_put() / mdb_page_dirty() Product: LMDB Version: 0.9.26 Hardware: All OS: Linux Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: nate(a)kde.org Target Milestone: --- The KDE Baloo file indexer uses lmdb as its database (source code available at https://invent.kde.org/frameworks/baloo). Our most common crash, with over 100 duplicate bug reports, is in lmdb. Here's the bug report tracking it: https://bugs.kde.org/show_bug.cgi?id=389848. The version of lmdb does not seem to matter much. We have bug reports from Arch users with lmdb 0.9.26 as well as bug reports from people using many earlier versions.

[Issue 9736] New: pwrite bug in OSX breaking LMDB promise about the maximum value size
by openldap-its＠openldap.org 15 Apr '26

15 Apr '26

https://bugs.openldap.org/show_bug.cgi?id=9736 Issue ID: 9736 Summary: pwrite bug in OSX breaking LMDB promise about the maximum value size Product: LMDB Version: unspecified Hardware: All OS: Mac OS Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: renault.cle(a)gmail.com Target Milestone: --- Hi, I was working with LMDB and found an issue when trying to write a value of approximately 3.3GiB in the database, I dive into the LMDB source code of the mdb_put method using the lldb debugger and found out that it was not related to an issue in LMDB itself but rather a bug in the pwrite function of the Mac OS libc implementation. The pwrite function is given four parameters, the file descriptor, the buffer, the count of bytes to write from the buffer and, the offset of where to write it in the file. On Mac OS the count of bytes is a size_t that must be a 64bits unsigned integer but when you call pwrite with a number bigger or equal to 2^31 it returns an error 22 (invalid argument). LMDB was returning a 22 error from the mdb_put call and not an EINVAL because the error was cause by an internal issue and not something catchable by LMDB. I am not sure about what we can do, can we implement this single pwrite [1] as multiple pwrite with counts smaller than 2^31 in a loop, just for Mac OS? Like for Windows where we do specific things for this operating system too? I also found this issue on the RocksDB repository [2] about a similar problem they have with pwrite and write on Mac OS it seems. I understand that this is not a real promise that LMDB is specifying but rather an "in theory" rule [3]. Thank you for your time, kero [1]: https://github.com/LMDB/lmdb/blob/01b1b7dc204abdf3849536979205dc9e3a0e3ece/… [2]: https://github.com/facebook/rocksdb/issues/5169 [3]: http://www.lmdb.tech/doc/group__mdb.html#structMDB__val -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9431] New: back-mdb: Always have an equality index for objectClass

As this is a hard requirement it should be automatic with back-mdb. Why this wasn't done in the past with other backends isn't exactly clear, it may have been due to their requirements to have additional cache layers. That however is not necessary with back-mdb. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10363] New: Implement a target connection time-to-live in asyncmeta

To avoid too many target connections timing out at once, a minimum reset interval per target should also be configurable. So, a configuration of: conn-ttl 5s 5s would mean connections have a 5 seconds time-to-live, but a connection should be reset no more frequently that once every 5 seconds per target.
