Summary
Fixes #1328.
InMemoryEnv::NewAppendableFile()currently creates a newFileStatefor missing files but does not store that pointer back intofile_map_. The map entry remains null, so later operations that look up the filename can dereference a nullFileState.This stores the newly-created
FileStatein the map and adds a regression test that creates a file withNewAppendableFile(), appends data, then verifies size and sequential reads through the environment.Validation
