https://bugs.openldap.org/show_bug.cgi?id=10066 Issue ID: 10066 Summary: fsync -> fcntl(F_FULLFSYNC) on Apple platforms? 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: christophersauer(a)pacbell.net Target Milestone: --- Hi, Howard, I was thinking of adopting LMDB for a cross-platform project, but when quickly browsing the code, didn't see specializations for Apple platform' weakened fsync -> fcntl(F_FULLFSYNC). (Doc quick link, if useful: https://developer.apple.com/library/archive/documentation/System/Conceptual…) Should I be concerned? I think it's very likely that you're way ahead of me, but I just wanted to check in. (And couldn't otherwise find anything online about this.) Thanks so much for all you do!

[Issue 10054] New: Value size limited to 2,147,479,552 bytes

https://bugs.openldap.org/show_bug.cgi?id=10054 Issue ID: 10054 Summary: Value size limited to 2,147,479,552 bytes Product: LMDB Version: unspecified Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: louis(a)meilisearch.com Target Milestone: --- Hello, According to the documentation[0], a database that is not using `MDB_DUPSORT` can store values up to `0xffffffff` bytes (around 4GB). In practice, under Linux, the actual limit is `0x7ffff000` though (2^31 - 4096, so around 2GB). This is due to the write loop in `mdb_page_flush`. The `wsize` value determining how many bytes will be written can be as big as `4096*dp->mp_pages`[1], and the number of overflow pages grows with the size of the value put inside the DB. The `wsize` is not split in smaller chunks in the case where there are many overflow pages to write, and as a result the call to `pwrite`[2] does not perform a full write, but only a "short" write of 2147479552 bytes (the maximum allowed on a call to `pwrite` on Linux[3]). This would be OK if the short write condition was handled by looping and performing another `pwrite` with the rest of the data, but instead `EIO` is returned[4]. There seems to be a related, but different issue on macOS when trying to `pwrite` more the 2^31 bytes, that was already reported[5]. This issue was reported to me by a Meilisearch user because it causes their database indexing to fail[6]. I had to investigate a bit because their setup was peculiar (high number of documents in their database) and the `EIO` error code is not very descriptive of the underlying issue. I join a C reproducer of the issue that attempts to add a 2147479553 bytes value to the DB and fails with `EIO` (decreasing `nb_items` to a smaller value such as `2107479552` does succeed)[7].
