Hi Howard,

Any plan on making LMDB work on OpenBSD?

Not sure what action you're expecting from us. Theo made it quite clear that OpenBSD does not and will not have a unified buffer cache.

1) I did not read that anywhere. I guess it's waiting to be solved, just like >4GB buffer cache support.

OpenBSD should deliver LMDB in the MDB_WRITEMAP mode. (http://lmdb.tech/doc/group__mdb.html)

Fine, let OpenBSD do that. Along with release notes saying that OpenBSD's port of LMDB doesn't provide any protection from stray pointer overwrites.

2) Yes!

That is perfect for now.

3) $ git clone https://github.com/LMDB/lmdb $ cd lmdb/libraries/liblmdb $ make

It does build on OpenBSD.

Should liblmdb.so work perfectly out of the box (as long as I stick to MDB_WRITEMAP only)?

I.e. this is with your blessing.

4) The only OpenBSD-specific behavior that could be relevant, then, would be to "disable" MDB_RDONLY by forcing MDB_WRITEMAP on the platform for now?

5) Should the tests work out of the box?

(At least some effort has been done e.g. https://gitlab.com/mdb/sqlightning/issues/6 )

The repos on gitlab.com are corrupted and have been abandoned. The only official repo is on openldap.org.

6) Ok
