Hello,

I like to implement an autogrow functionality for LMDB.

The documentation for mdb_env_set_mapsize says that no transactions should be active when using this function.

When looking at the code I can see that the function only checks if there is an active WRITE transaction and in this case it returns an error.

Is it possible to reuse existing READ transactions or even associated cursors after mdb_env_set_mapsize has been called?

Thank you and best regards,

Ken
