wallet To-Do List
Release 1.0:
* Write the LDAP entitlement ACL verifier.
* Write the PTS ACL verifier.
* Add POD testing for the client and server programs.
* Add POD coverage testing using Test::POD::Coverage for the server
modules.
* Provide a way to get history for deleted objects and ACLs.
* Display ACL names rather than index numbers when displaying history of
owner and acl_* settings.
* Provide an interface to list all objects in the database by type, by
owner (including null), or by all uses of an ACL.
* Provide an interface to list all ACLs in the database. Most
interestingly, an interface to list all empty ACLs.
* Add a help function to wallet-backend listing the commands.
* The client may not compile against Heimdal due to changes in how the
krb5_keyblock structure is laid out. Check and fix.
* Rewrite the client test suite to use Perl and to make better use of
shared code so that it can be broken into function components.
* Add a test suite for kasetkey.
* Log failures in the wallet-backend properly, which also requires
catching all exceptions.
* Implement special handling for keytabs in the wallet client.
* Add support to the wallet client for getting Kerberos tickets, using the
-u option similar to leland_srvtab. Needs good error messages on
Kerberos failures.
* Error messages from ACL operations should refer to the ACLs by name
instead of by ID.
* Add the database schema version to a global table so that we can use it
to support schema upgrades in the future.
* On upgrades, support adding new object types and ACL verifiers to the
class tables.
* Write a wallet-admin program and a corresponding Wallet::Admin class to
provide an interface to things like database initialization and,
eventually, upgrades. Move the methods to add additional class mappings
from Wallet::Schema to Wallet::Admin and the initialize and reinitialize
methods from Wallet::Server to Wallet::Admin.
* Implement store support in the wallet client. Add an option to read the
data from a file. The initial implementation, depending on the
underlying remctl support, may have to ban nul characters in the
uploaded data.
* Implement a simple file wallet object. Document a naming convention for
those files (group-service, perhaps).
* Rename Wallet::ACL::* to Wallet::Verifier::*. Add Wallet::ACL as a
generic interface with Wallet::ACL::Database and Wallet::ACL::List
implementations (or some similar name) so that we can create and check
an ACL without having to write it into the database. Redo default ACL
creation using that functionality.
Future work:
* Write a conventions document for ACL naming, object naming, and similar
issues.
* Write a future design and roadmap document to collect notes about how
unimplemented features should be handled.
* Support limiting returned history information by timestamp.
* There is a lot of duplicate code in wallet-backend. Convert that to
use some sort of data-driven model with argument count and flags so
that the method calls can be written only once.
* There's a lot of code duplication in the dispatch functions in the
Wallet::Server class. Find a way to rewrite that so that the dispatch
doesn't duplicate the same code patterns.
* Refactor the test suite for the wallet backend to try to reduce the
duplicated code.
* Pull common test suite code into a Perl library that can be reused.
* Add a function to wallet-admin to purge expired entries. Possibly also
check expiration before allowing anyone to get or store objects.
* Add a comment field for objects that can be set by the owner.
* The keytab backend currently only supports MIT Kerberos. Add support
for Heimdal. This should probably be done by writing a separate class
that handles the kadmin operations that can be subclassed and that
dynamically chooses its implementation based on run-time configuration.
* When reading configuration from krb5.conf, we should first try to
determine our principal from any existing K5 ticket cache (after
obtaining tickets if -u was given) and extract the realm from that
principal, using it as the default realm when reading configuration
information.
* Implement an ssh keypair wallet object. The server can run ssh-keygen
to generate a public/private key pair and return both to the client,
which would split them apart. Used primarily for host keys. May need a
side table to store key types, or a naming convention.
* Implement an X.509 certificate object. I expect this would store the
public and private key as a single file in the same format that Apache
can read for combined public and private keys. There were requests for
storing the CSR, but I don't see why you'd want to do that. Start with
store support.
* Implement an X.509 CA so that you can get certificate objects without
storing them first. Need to resolve naming conventions if you want to
run multiple CAs on the same wallet server (but why?). Should this be a
different type than stored certificates?
* Add details to design-api on how to write one's own ACL verifiers and
object implementations and register them.
* Add support for enforcing a naming policy through another policy
function.
* Add readline support to the wallet client to make it easier to issue
multiple commands.
* The wallet-backend and wallet documentation share the COMMANDS section.
Work out some means to assemble the documentation without duplicating
content.
* Add support for rekeying in the wallet client. Need to resolve how to
get a list of principals to rekey and which keytabs to work on. This
possibly should be a separate binary from the regular wallet client
binary.
* Document using the wallet system over something other than remctl.
* Provide a REST implementation of the wallet server.
* Provide a CGI implementation of the wallet server.
* Document all diagnostics for all wallet APIs.
* Write a test suite to scan all wallet code looking for diagnostics that
aren't in the documentation and warn about them.
* The Wallet::Config class is very ugly and could use some better internal
API to reference the variables in it.
* Use Class::DBI and Class::Trigger to handle the data access layer rather
than writing SQL directly, and implement the logging requirements with
triggers rather than explicit SQL. This may also replace
Wallet::Schema.
May or may not be good ideas:
* Consider using Class::Accessor to get rid of the scaffolding code to
access object data, and a Wallet::Base class to handle things like the
error() method common to many classes.
* Remove the hard-coded ADMIN ACL in the server with something more
configurable, perhaps a global ACL table or something.
