Hi, I'm interested in understanding these functions better. These are not criticisms.. since these functions are called rarely, I have no problem synchronizing them. I ask only for curiosity's sake.
* mdb_env_close: "Only a single thread may call this function." Why can't different environments (separate files/dirs on disk) be closed from different threads? * mdb_dbi_close: "Handles should only be closed by a single thread." Why can't at least databases on different environments (separate files/dirs on disk) be closed from different threads? * mdb_dbi_open: "This function must not be called from multiple concurrent transactions in the same process." Why can't this function be called from different threads to open at least databases on different environments (separate files/dirs on disk)? What are the reasons for these limitations, under the hood? Could these functions have been designed in a different way, to allow for more multithreading (again, I'm not asking for this, I'm just curious). - Sam
