Branch point for: yamt-pagecache
Add the constant database reader (cdbr(3)) and writer ((cdbw(3)). They implement a space efficent write-once database with fast access path. Switch the services(5) database to use cdb. The size of the database file decreases from 2.1MB disk space to 307KB. Access performance is about the same if setservent(0) is used and about an order of magnitude faster otherwise. services_mkdb defaults to the new format, but can optionally create the old db(3) format as well for statically linked legacy applications.
This form allows you to request diff's between any two revisions of a file. You may select a symbolic revision name using the selection box or you may type in a numeric name using the type-in text box.
