 Open Issues/To-Do Items  Open Issues/To-Do Items
   
  Targeted for 0.5 Alpha 2   Targeted for 0.5 Alpha 3
   
     * ZConfig Integration      * peak.ddt
   
       - A 'config.ZConfig' module that provides "PEAK-aware" versions of ZConfig        - A bit more doc and demos
         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.  
   
     * 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.  
   
     * Add reference docs for 'peak.interface'  
   
     * Create tutorial section for 'peak.interface'  
   
  Targeted for 0.5 Beta 1  
   
     * Updated reference docstrings for 'peak.api', 'peak.binding',  
       'peak.config', 'peak.exceptions', and 'peak.naming'.  
   
     * Finish tutorial chapter 2 (?)  
   
     * Web publishing framework sufficient to deploy page-based or object-  
       published apps  
   
     * Get XMI writing in place, w/transaction support  
   
     * On-the-fly class combination (think "runtime module inheritance",  
       without the modules) for DMs.  
   
   
   
  Targeted for 0.5 Final Release (or sooner)  
   
     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  
           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?  
   
   
   
    Targeted for 0.5 Alpha 4
   
       * 'ILoadingService', 'IObjectLoader' and 'load:kind@URL' scheme
   
       * peak.config
   
         - "service zones" or "service groups" to do smarter service groupings
   
         - Replace IMainLoop activity monitoring with a plugin-based mechanism?
   
         - plugin keys ordered by definition sequence, rather than randomly
   
         - ZConfig factory support to allow "smart" interpretation of strings,
           section names, etc.
   
         - Writable and subscribable config sources, including editable .ini's
   
       * peak.running.logs
   
         - Separate formatters from publishers
   
         - ZConfig schema for logging plugins, allowing multiple handlers/category
   
       * peak.running.commands
   
          - Add "error formatting" and "error reporting" services
   
          - Add option parsing framework based on optparse (backported to 2.2)
   
       * peak.binding
   
         - Cleanup/document attribute binding interface
   
       * peak.running.timers
   
         - Factor out state into separate object so timers aren't shared state
   
         - Look at possible integration of peak.query and cursor formatters, in
           order to view stats as an in-memory mini-DB w/reporting.
   
   
       * Transaction/storage refactorings
   
         - transaction scopes for commands and tasks
   
         - integrate locks with transactions
   
         - transactable persistent queues
   
         - DM.find()/DM.get() queries
   
       * peak.web
   
          - clean up DOMlet parse/build framework (e.g. add line number info, make
            'define' clauses allow multiple names)
   
  Future Releases         - default error templates, w/useful info
   
   (Note: some of the below is held-over from TransWarp and may no longer be         - A set of simple, basic form controls that handle value rendering only
   relevant as written, they are being kept on this list as placeholders for           (form metadata, validation, etc. will be handled by peak.web.forms in
   ideas or problem areas that may need to be re-considered in future.)           a later release)
   
   Miscellaneous         - try/catch DOMlet (and related error rendering interface/framework)
   
     * Functional tests that access "real" databases, LDAP, etc.         - allow use of // in DOMlets' data paths, to access resource space
   
   Simulator/Module Inheritance         - DOMlets for layout/region, as defined in "A layout framework":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000684.html
   
     * Allow 'declareModule()' to bootstrap non-existent modules; this might         - conditional GET support (last modified/ETag) for static resources
       let us create "virtual packages" made by assembling other packages and  
       modules.  
   
     * Need a strategy for handling "del" operations; they are currently         - image resources
       untrapped.  This might be okay under most circumstances, but need to  
       consider edge cases.  
   
     * 'makeClass()' should probably become part of the core API, where  
       it can be used to resolve __metaclass__ conflicts during the first  
       pass of importing a module (prior to running 'setupModule()')  
   
   
   Messaging/ObjectSpaces  
   
     * Support for sending and receiving remote cache invalidation  
       messages between DataManagers.  
   
          - 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.model      peak.storage
   
     * 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          - unit tests for more complex object scenarios: references, thunks..?
   
        * How much of framework needs extensibility?  Should the predicate      peak.naming
          classes be placed in the StructuralModel's namespace so that predicates  
          have their meaning assigned by the StructuralModel implementation?  
   
           - 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?

Line 160 
   
   
   
   peak.metamodels.uml  
   
     * Helper methods in Elements & Services for marshalling, common queries, etc.  
   
     * Generator framework   Targeted for version 0.6
   
       - Tagged values in stereotypes vs. main values?     * Functional/acceptance tests that access "real" databases, LDAP, etc.
   
       - Should tagged values be copied directly into templates?  Treated as     * Get XMI writing in place, w/transaction support
         Python expressions?  
   
       - Should Services be generated using an Element class' "static"     * Generate UML 1.5 and CWM 1.0 and 1.1, and add them to the
         (class-scope) methods/attributes?       'setup.py' package lists.
   
         - Are association-ends scoped?     * On-the-fly class combination (think "runtime module inheritance",
        but possibly without the modules) for DMs.
   
         - Would it be better to seperate them?     * Lock management interfaces/API for peak.storage
   
       - What determines whether an implemented Service actually stores objects     * Support for sending and receiving remote cache invalidation
         or delegates this to its subclass services?       messages between DataManagers.
   
     * Simple Zope product demo (upload XMI, then browse the model via the web)     * 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.)
