ConfigBase::MAX_NAME_LENGTH

The maximum length of a configuration object name.

Many filesystems (including HFS, NTFS, and ext4) have a maximum file name length of 255 characters. To ensure that no configuration objects incompatible with this limitation are created, we enforce a maximum name length of 250 characters (leaving 5 characters for the file extension).

Configuration objects not stored on the filesystem should still be restricted in name length so name can be used as a cache key.
