  Targeted for 0.5 Alpha 3   Targeted for 0.5 Alpha 3
   
     * Refactor binding and naming frameworks to      * peak.ddt
   
       - make indirection convenient (e.g. bind to looking up something from        - A bit more doc and demos
         another binding)  
   
     * peak.binding  
   
        - Cleanup/document attribute binding interface  
   
        - Attribute -> AttribDef  
   
        - binding.AttribDef has an adequate docstring  
   
        - Ensure default __repr__'s for all bindings are acceptable  
   
        - Update tutorial for current kwargs  
   
        - Investigate whether suggestParentComponent() should be suppressed when  
          the value is computed by the binding, or if perhaps 'suggestParent'  
          should be set to 'False' by default for some kinds of bindings.  
   
     * peak.web (some of this may get bumped to alpha 4)  
   
        - default error templates, w/useful info  
   
        - Refactor skin/layer/resource machinery so that layers can be shared  
          between skins (because i18n will probably want skins and that's going  
          to greatly multiply memory requirements)  
   
        - clean up DOMlet parse/build framework (e.g. add line number info)  
   
        - 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)  
   
        - try/catch DOMlet (and related error rendering interface/framework)  
   
  Targeted for 0.5 Alpha 4  
   
     * Transaction/storage refactorings  
   
       - transaction scopes for commands and tasks  
   
       - integrate locks with transactions  
   
       - transactable persistent queues  
   
       - DM.find()/DM.get() queries  
   
   
     * peak.web  
   
        - allow use of // in DOMlets' data paths, to access resource space  
   
        - DOMlets for layout/region, as defined in "A layout framework":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000684.html  
   
        - conditional GET support (last modified/ETag) for static resources  
   
        - image resources  
   
        - the return of the Specialist  
   
     * "Pre-forking event driven services":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000697.html  
   
     * Have a way to easily in-line custom component usage (e.g. automatically  
       create a subclass component with specified 'bindTo' bindings to get its  
       configuration).  
   
     * Implement "contextual protocols" (c.f. "object teams") and "parameterized  
       protocols" (E.g. 'ListOf(IFoo)', 'MappingOf(keys=IBar,values=IBaz)')  
   
   
   
Line 80 
Line 32 
   
   
   
  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?  
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
  Targeted for version 0.6  
   
    * 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  
   
    * 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.)  
   
   
   
   
   
   
Line 148 
Line 39 
   
   
   
    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)
   
  Future Releases      * peak.binding
   
   (Note: some of the below is held-over from TransWarp and may no longer be        - Cleanup/document attribute binding interface
   relevant as written, they are being kept on this list as placeholders for  
   ideas or problem areas that may need to be re-considered in future.)  
   
   Miscellaneous      * peak.running.timers
   
     * Functional tests that access "real" databases, LDAP, etc.        - Factor out state into separate object so timers aren't shared state
   
   Simulator/Module Inheritance        - Look at possible integration of peak.query and cursor formatters, in
           order to view stats as an in-memory mini-DB w/reporting.
   
     * Allow 'declareModule()' to bootstrap non-existent modules; this might  
       let us create "virtual packages" made by assembling other packages and  
       modules.  
   
     * Need a strategy for handling "del" operations; they are currently      * Transaction/storage refactorings
       untrapped.  This might be okay under most circumstances, but need to  
       consider edge cases.  
   
     * 'makeClass()' should probably become part of the core API, where        - transaction scopes for commands and tasks
       it can be used to resolve __metaclass__ conflicts during the first  
       pass of importing a module (prior to running 'setupModule()')  
   
         - integrate locks with transactions
   
   Messaging/ObjectSpaces        - transactable persistent queues
   
     * Support for sending and receiving remote cache invalidation        - DM.find()/DM.get() queries
       messages between DataManagers.  
   
       * peak.web
   
          - clean up DOMlet parse/build framework (e.g. add line number info, make
            'define' clauses allow multiple names)
   
          - default error templates, w/useful info
   
          - 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)
   
          - try/catch DOMlet (and related error rendering interface/framework)
   
          - allow use of // in DOMlets' data paths, to access resource space
   
          - DOMlets for layout/region, as defined in "A layout framework":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000684.html
   
          - conditional GET support (last modified/ETag) for static resources
   
          - image resources
   
          - 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).
   
   peak.model      * Drop 'persistence' package, since ZODB 4 has been derailed.  Change to
         "state-delegation" model, which will integrate better with 'peak.query'.
   
     * Implement WarpCORE-oriented structural model, w/Querying support  
   
     * "Indexed" version of in-memory model?   Targeted for 0.5 Beta 1
   
       * Up-to-date reference docstrings for all packages
   
     Queries      * Finish tutorial chapter 2 (?)
   
        * Refactor to use interfaces, if appropriate      * Web publishing framework sufficient to deploy page-based or object-
         published apps
   
        * Incorporate into AbstractModel?  
   
          - Pros:  
   
            * Queries always available   Targeted for 0.5 Final Release (or sooner)
   
            * Each StructuralModel implementation can easily include its own      peak.storage
              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 demo (browse XMI 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.)
