[Issue 10523] New: LMDBv1.0 encryption tromps on checksums
by openldap-its＠openldap.org 30 Jun '26

https://bugs.openldap.org/show_bug.cgi?id=10523 Issue ID: 10523 Summary: LMDBv1.0 encryption tromps on checksums Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: dan(a)shearer.org Target Milestone: --- In mdb.c , encryption and checksums cannot be used together even though it looks like that was the intention. `OVPAGES` accounts for both `me_sumsize` and `me_esumsize`, so that suggests there should be room. However, with checksums on, the authentication-data slot `enckeys[2]` (sized `me_esumsize`, placed at the end of the page) overlaps the region the per-page checksum (`me_sumsize`) already used. So the authentication data overwrites the checksum. There may also be an ordering problem with which of set_checksum and set_encrypt are called first, but that will go away if encryption stops tromping on checksums. There are use cases for having both turned on, and the one I care about is that implementers of encryption often do a terrible job. I am currently being an implementer of encryption so I want to have a way to see if I'm doing a terrible job. One way is to switch on checksums, because the way LMDB works is that checksums verify that the plain text stays the same having been en/decrypted. It is possible (indeed relatively common) to have silently failing encryption pass tests because the rubbish it generates is consistent rubbish. Besides, it's a great stress test, or would be if LMDB didn't corrupt itself instantly. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10203] New: no pkgconfig file included for liblmdb

https://bugs.openldap.org/show_bug.cgi?id=10203 Issue ID: 10203 Summary: no pkgconfig file included for liblmdb Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: otto(a)drijf.net Target Milestone: --- liblmdb does not ship with a pkgconfig file. More and more build systems rely on presense of a pkgconfig file, so it would be nice if liblmdb installed oneone. An example: prefix=/usr/local exec_prefix=${prefix} libdir=${prefix}/lib includedir=${prefix}/include Name: lmdb Description: Lightning memory-mapped database: key-value data store URL: https://www.symas.com/symas-embedded-database-lmdb Version: 0.9.32 Libs: -L${libdir} -llmdb Cflags: -I${includedir} Thanks. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10402] New: Feature request: parameter for mdb_env_copy to exclude databases
by openldap-its＠openldap.org 30 Jun '26

https://bugs.openldap.org/show_bug.cgi?id=10402 Issue ID: 10402 Summary: Feature request: parameter for mdb_env_copy to exclude databases Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs(a)openldap.org Reporter: jeffro256(a)tutanota.com Target Milestone: --- ## Desired behavior New overload or API modification to `mdb_env_copy{...}()` which allows passing a list of names of databases to exclude from the environment copy. ## Example use-case The Monero blockchain database [1] has the option to derived a "pruned" database for space-saving purposes. This removes some ~60% of data which some users may find non-essential. Currently, the pruning code [2] copies each non-pruned table manually, specifying key ordering functions, DB flags, etc. It then drops some entries from the relevant "prunable tables". This, however, adds technical maintenance debt when databases are added/updated. A preferable alternative would be to write high-level modification code once and use an overload of `mdb_env_copy` which excludes copying database that we know in advance we don't want to copy. Then our pruning utility would work agnostic to database changes. ## Why Adding this functionality ourselves would involve re-writing large portions of `mdb_env_copyfd{0,1}` and `mdb_env_cwalk`, which requires either A) vendoring LMDB, or B) possibly breaking in future updates. You may understandably be of the opinion that the maintenance burden is an "us problem", and not deem pursuing this feature request worth it, but hopefully you seem the value in this utility. Thanks for y'alls hard work on LMDB. ## Links [1] https://github.com/monero-project/monero/blob/d32b5bfe18e2f5b979fa8dc3a8966… [2] https://github.com/monero-project/monero/blob/master/src/blockchain_utiliti… -- You are receiving this mail because: You are on the CC list for the issue.
