[WIP] adjustments while implementing ACL

[dbu]

Principal is something from java.security, so its not jcr specific at all. meaning there is no infrastructure to build principals.

i guess we either need a factory method on the AccessControlManager or provide the trivial implementation in PHPCR directly so people can use new.

i wonder how the java side of this actually works, if its using all that fancy stuff to in the end do a string comparison because the principal name and the username used in the jackrabbit connection.

I guess removing stuff from the interface is safe

[dbu]

in this case yes. if it was implemented anywhere, consumers of the api might rely on the methods so its technically still a BC. but i would be really surprised if anybody implemented those interfaces and never told us.

ah, we even have this note, so really no worries: https://github.com/phpcr/phpcr/blob/master/doc/JCR_TO_PHPCR.txt#L310-L311

we should update that documentation when we are good, though.
