 Open Issues/To-Do Items   Targeted for 0.5 Alpha 4
   
  Targeted for 0.5 Alpha 1      * peak.config
   
     * Finish tutorial chapter 2        - "service zones" or "service groups" to do smarter service groupings
   
     * Updated reference docstrings for 'peak.api', 'peak.binding',        - Replace IMainLoop activity monitoring with a plugin-based mechanism?
       'peak.config', 'peak.exceptions', and 'peak.naming'.  
   
         - plugin keys ordered by definition sequence, rather than randomly
   
  Targeted for 0.5 Final Release (or sooner)        - ZConfig factory support to allow "smart" interpretation of strings,
           section names, etc.
   
     General  
   
         * Tutorial complete through chapter 4  
   
     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        - Writable and subscribable config sources, including editable .ini's
           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  
   
         - more docs for new 'cluster' tools      * peak.running.logs
   
         - make 'cluster' parser complain about things that would cause        - Separate formatters from publishers
           the clusterit tools to choke or barf on the file, or which would  
           produce ambiguous or unintended results.  
   
         - finish misc tasks on peak.running.logs's TODO list  
   
         - simple daemons comparable to those in MetaDaemon        - ZConfig schema for logging plugins, allowing multiple handlers/category
   
         - unit tests for daemons      * peak.running.commands
   
         - docstrings for reference         - Add "error formatting" and "error reporting" services
   
     peak.config         - Add option parsing framework based on optparse (backported to 2.2)
   
         - "Rule"-oriented configuration files (section specifies component      * peak.binding
           rather than property name prefix), so that daemons and other simple  
           apps can be fully configured and run via a config file.  
   
     peak.util        - Cleanup/document attribute binding interface
   
         - docstrings for reference  
   
         - more unit tests?  
   
   
   
Line 75 
Line 39 
   
   
   
       * Transaction/storage refactorings
   
         - transaction scopes for commands and tasks
   
         - integrate locks with transactions
   
         - transactable persistent queues
   
         - DM.find()/DM.get() queries
   
  Future Releases      * peak.web
   
   (Note: some of the below is held-over from TransWarp and may no longer be         - clean up DOMlet parse/build framework (e.g. add line number info, make
   relevant as written, they are being kept on this list as placeholders for           'define' clauses allow multiple names)
   ideas or problem areas that may need to be re-considered in future.)  
   
          - default error templates, w/useful info
   
   Simulator/Module Inheritance         - A set of simple, basic form controls that handle value rendering only
            (form metadata, validation, etc. will be handled by peak.web.forms in
            a later release)
   
     * Need a strategy for handling "del" operations; they are currently         - try/catch DOMlet (and related error rendering interface/framework)
       untrapped.  This might be okay under most circumstances, but need to  
       consider edge cases.  
   
     * 'makeClass()' should probably become part of the core API, where         - allow use of // in DOMlets' data paths, to access resource space
       it can be used to resolve __metaclass__ conflicts during the first  
       pass of importing a module (prior to running 'setupModule()')  
   
          - DOMlets for layout/region, as defined in "A layout framework":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000684.html
   
   Messaging/ObjectSpaces         - conditional GET support (last modified/ETag) for static resources
   
     * Support for sending and receiving remote cache invalidation         - image resources
       messages between RecordManagers.  
   
          - the return of the Specialist
   
       * Have a way to easily in-line custom component usage (e.g. automatically
         create a subclass component with specified 'Obtain' or 'Make' bindings to
         get its configuration).
   
       * Drop 'persistence' package, since ZODB 4 has been derailed.  Change to
         "state-delegation" model, which will integrate better with 'peak.query'.
   
   
    Targeted for 0.5 Beta 1
   
       * Up-to-date reference docstrings for all packages
   
       * Finish tutorial chapter 2 (?)
   
       * Web publishing framework sufficient to deploy page-based or object-
         published apps
   
   
   
    Targeted for 0.5 Final Release (or sooner)
   
       peak.storage
   
           - unit tests for more complex object scenarios: references, thunks..?
   
       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 a filesystem context)
   
           - rework smtp: to return a factory object that supports open().
             Also think about whether smtp should move to peak.net?
   
   
   peak.model  
   
     * A way to generate Z3 Interfaces from Feature-based specifications?  
   
     * Implement WarpCORE-oriented structural model, w/Querying support  
   
     * "Indexed" version of in-memory model?  
   
   
     Queries  
   
        * Refactor to use interfaces, if appropriate  
   
        * Incorporate into AbstractModel?  
   
          - Pros:  
   
            * Queries always available  
   
            * Each StructuralModel implementation can easily include its own  
              performance-tuned version of the basic items.  
   
          - Con: default implementation doesn't perform well on large datasets  
   
        * How much of framework needs extensibility?  Should the predicate  
          classes be placed in the StructuralModel's namespace so that predicates  
          have their meaning assigned by the StructuralModel implementation?  
   
    Targeted for version 0.6
   
      * Functional/acceptance tests that access "real" databases, LDAP, etc.
   
      * Get XMI writing in place, w/transaction support
   
      * Generate UML 1.5 and CWM 1.0 and 1.1, and add them to the
        'setup.py' package lists.
   
      * On-the-fly class combination (think "runtime module inheritance",
        but possibly without the modules) for DMs.
   
      * Lock management interfaces/API for peak.storage
   
      * Support for sending and receiving remote cache invalidation
        messages between DataManagers.
   
      * 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.  (Or replace with ZConfig
        schema that can generate clusterit files.  And/or replace clusterit
        tools with PEAK ones.)
   
   
   
   
   
   
   peak.metamodels.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.  
   
     * Helper methods in Elements & Services for marshalling, common queries, etc.  
   
     * Generator framework  
   
       - Tagged values in stereotypes vs. main values?  
   
       - Should tagged values be copied directly into templates?  Treated as  
         Python expressions?  
   
       - Should Services be generated using an Element class' "static"  
         (class-scope) methods/attributes?  
   
         - Are association-ends scoped?  
   
         - Would it be better to seperate them?  
   
       - What determines whether an implemented Service actually stores objects  
         or delegates this to its subclass services?  
   
     * Simple Zope product demo (upload XMI, then browse the model via the web)
