The Lightning Memory-mapped Database (LMDB) is designed around the virtual memory facilities found in modern operating systems, Multi-version Concurrency Control (MVCC), and Single-Level Store (SLS) concepts. This design is quite different than those of more traditional databases and, in operation, it can mimic behaviors that system administrators have been trained to recognize as signs of trouble. With LMDB, though, the behaviors are normal, but nonetheless this leads to the following questions:
Character strings are an essential component of any programming language, but C Strings were a bit unusual in not defining an explicit string type. The C standard specifies some standard library functions for operating on C strings, which gives them a de-facto type and standard methods, but the standard library functions were horrible when first invented in the 1970s, and nothing sane has replaced them yet. In honor of the Chinese Lunar New Year, and the 30th anniversary of this rant, I delve once more into these problems.
