 Open Issues/To-Do Items  Open Issues/To-Do Items
   
  Targeted for 0.2 Final Release   Release Checklist for 0.5 Alpha 1
   
       - Add 'fcgiapp' module sources to distribution; update README/INSTALL to credit
         DC and OpenMarket and reference their licenses.
   
   
   Targeted for 0.5 Alpha 2
   
       * ZConfig Integration
   
         - A 'config.ZConfig' module that provides "PEAK-aware" versions of ZConfig
           services (e.g. it will use 'peak.naming' to resolve URLs)
   
         - App startup tools based on ZConfig files.
   
         - Sample 'AdaptiveTask' classes that perform the same functions as those in
           the MetaDaemon package, with a ZConfig schema to run them in a daemon-like
           application.
   
         - Generate ZConfig schemas from 'peak.model' or MOF models?
   
   
       * Fix issue w/reading XMI 1.1 files where metamodel has nested packages
   
       * Generate UML 1.4 and 1.5 and CWM 1.0 and 1.1, and add them to the
         'setup.py' package lists.
   
       * Get XMI writing in place, w/transaction support
   
       * 'peak.running' refactorings: use standard 'logging' module's log levels,
          add 'logging' distro to 'peak.util' for 2.2 backward compatibility,
          and possibly adjust cluster stuff to work off ZConfig primary and
          generate clustertools file(s).
   
   
   
   
   
   
    Targeted for 0.5 Beta 1
   
       * 'peak.naming' refactorings: 'peak.model'-based syntax utilities for
          creating address syntaxes.
   
       * Updated reference docstrings for 'peak.api', 'peak.binding',
         'peak.config', 'peak.exceptions', and 'peak.naming'.
   
       * Finish tutorial chapter 2 (?)
   
       * On-the-fly class combination (think "runtime module inheritance",
         without the modules) for DMs.
   
   
   
   
   
   
     API.Modules  
   
       * Add tests for 'adviseModule()' API  
   
       * Add checks and warnings for ambiguous re-assignments and operations  
         on mutables  (i.e. setting items or attrs), plus "safe" setattr  
   
     Database  
   
       * Create test suite to check proper transactional functioning, cache  
         consistency, queueing behavior, and typemap management.  
   
       * Update Interfaces to reflect current API, and document internals  
   
     General  
   
       * Update tutorial documentation  
   
   
  Ideas for 0.3 Release  
   
     Dispatching  
   
       * Virtual features to implement retrieving the other end of a  
         relationship from another Specialist.  
   
     SEF  
   
       * Persistent SEF module, with Base.__getstate__ supporting omission  
         of Once attributes, and DynamicBinding setting _p_changed on  
         instantiation.  
   
       * A way to generate Z3 Interfaces from Feature-based specifications?  
   
   
     Database  
   
       * Rack-like object to do persistent storage of Elements?  
   
   
   
   
   
   
    Targeted for 0.5 Final Release (or sooner)
   
     General      General
   
       * Profiling and performance tuning of module inheritance and other          * Tutorial complete through chapter 4
         core features of API and SEF.  
       peak.storage
   
           - unit tests for more complex object scenarios: references, thunks..?
   
           - lock management interfaces/API
   
           - docstrings for reference
   
       peak.model
   
           - clean up TW docstrings & interfaces
   
       peak.naming
   
           - useful example "flat" naming context (e.g. like AppUtils.URLkeys)
   
           - useful example hierarchical naming context (e.g. like JNDI's LDAP
             context or filesystem context)
   
           - rework smtp: to return a factory object that supports open().
             Also think about whether smtp should move elsewhere. Maybe
             there should be peak.network or peak.internet for things like
             smtp, ftp, etc contexts?
   
       peak.running
   
           - make 'cluster' parser complain about things that would cause
             the clusterit tools to choke or barf on the file, or which would
             produce ambiguous or unintended results.
   
           - simple daemons comparable to those in MetaDaemon, unit tests
   
           - docstrings for reference
   
   
       peak.config
   
           - "Rule"-oriented configuration files (section specifies component
             rather than property name prefix), so that daemons and other simple
             apps can be fully configured and run via a config file.
   
       peak.util
   
           - docstrings for reference
   
           - more unit tests?

     relevant as written, they are being kept on this list as placeholders for

     Miscellaneous
   
       * Functional tests that access "real" databases, LDAP, etc.
   
   Simulator/Module Inheritance    Simulator/Module Inheritance
   
       * Allow 'declareModule()' to bootstrap non-existent modules; this might
         let us create "virtual packages" made by assembling other packages and
         modules.

     * Review other-end-notification protocols in the light of managed storage  
       models (e.g. database Records using virtual sequence objects as fields)  
   
     * Marshalling interface in Services; implementations for Enumeration, etc.  
   
     * More S-E-F metadata: features, subclasses, svc.<->class, nested services

   UML  
   
     * Need to write an MMX or XMI -> Python generator, and hook it back up into  
       the UML package, since we're right now relying on a module generated  
       by code that depends on stuff which is going away.

     * Document version of standard used  
   
     * Metamodel identity/version checking

     * Strict parsing and/or diagnostics on files that don't match the metamodel?  
   
     * UUID/GUID support  
   
     * Support for advanced references, external references?  
   
     * XML Namespaces (do any current XMI tools need this?  Which spec version  
       requires this?)  
   
     * DOM StructuralModel (so files can be edited without affecting vendor XMI  
       extensions)
