Issue ID: 10540 Summary: Clarify "Symas Dual-Use License" Product: LMDB Version: 1.0.0 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs@openldap.org Reporter: keno@alumni.harvard.edu Target Milestone: ---
Greetings from the Julia project. We recently grew an LMDB dependency (https://github.com/JuliaLang/julia/pull/61527), so I am trying to make sure we have the licensing information correct.
In particular, I am wondering about the "Symas Dual-Use License" which is referenced in these files:
- crypto.c - cryptoc.c - module.c - mtest_enc{,2,3,4}.c - mtest_remap.c
The license header says that a copy of the license is included in the LICENSE file, but this does not appear to be the case. I understand that there was previously an effort to dual license LMDB that did not end up happening (https://github.com/monero-project/meta/issues/85#issuecomment-361925678). Could you clarify if these license headers are a vestigal artifact of that process or if they are currently applicable and if the latter, could the appropriate license text be added to LICENSE?
Thanks! Keno

--- Comment #1 from Howard Chu hyc@openldap.org --- The dual license effort was abandoned. Only the OpenLDAP license is relevant.

--- Comment #2 from keno@alumni.harvard.edu --- Excellent, thanks for the quick reply. For license cleanliness, it'd be great to update those headers, but for our purposes, the reply here is sufficient. Thanks again!
