 Open Issues/To-Do Items  Open Issues/To-Do Items
   
  Release Checklist for 0.5 Alpha 1   Targeted for 0.5 Alpha 3
   
     - Unit tests for event-driven operations: IMainLoop, IPeriodicTask, and ITaskQueue      * peak.events migration
   
     - Cleanup/document attribute binding mechanism as an 'IAttributeBinding' interface        - Add tests for Twisted support
   
     - Make all API signatures start with context component      * peak.ddt
   
     - Finalize name for 'config.Application' - probably 'config.DefaultContext'        - A bit more doc and demos
   
     - Review binding tutorial and correct any errors relative to current APIs  
   
     - 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.  
   
     * 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  
   
     * Generate ZConfig schemas from 'peak.model' or MOF models?  
   
     * '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).  
   
     * 'peak.naming' refactorings: 'peak.model'-based syntax utilities for  
        creating address syntaxes.  
   
   
  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 (?)  
   
     * On-the-fly class combination (think "runtime module inheritance",  
       without the modules) for DMs.

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
   
  Targeted for 0.5 Final Release (or sooner)         - Add option parsing framework based on optparse (backported to 2.2)
   
     General      * peak.binding
   
         * Tutorial complete through chapter 4        - Cleanup/document attribute binding interface
   
     peak.storage      * peak.running.timers
   
         - unit tests for more complex object scenarios: references, thunks..?        - Factor out state into separate object so timers aren't shared state
   
         - lock management interfaces/API        - Look at possible integration of peak.query and cursor formatters, in
           order to view stats as an in-memory mini-DB w/reporting.
   
         - docstrings for reference  
   
     peak.model      * Transaction/storage refactorings
   
         - clean up TW docstrings & interfaces        - transaction scopes for commands and tasks
   
     peak.naming        - integrate locks with transactions
   
         - useful example "flat" naming context (e.g. like AppUtils.URLkeys)        - transactable persistent queues
   
         - useful example hierarchical naming context (e.g. like JNDI's LDAP        - DM.find()/DM.get() queries
           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      * peak.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.  
   
         - simple daemons comparable to those in MetaDaemon, unit tests         - clean up DOMlet parse/build framework (e.g. add line number info)
   
         - docstrings for reference         - 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)
   
     peak.config         - try/catch DOMlet (and related error rendering interface/framework)
   
         - "Rule"-oriented configuration files (section specifies component         - allow use of // in DOMlets' data paths, to access resource space
           rather than property name prefix), so that daemons and other simple  
           apps can be fully configured and run via a config file.  
   
     peak.util         - DOMlets for layout/region, as defined in "A layout framework":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000684.html
   
         - docstrings for reference         - conditional GET support (last modified/ETag) for static resources
   
         - more unit tests?  
   
          - 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).
   
       * 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?

  Future Releases  
   
   (Note: some of the below is held-over from TransWarp and may no longer be  
   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  
   
     * Functional tests that access "real" databases, LDAP, etc.  
   
   Simulator/Module Inheritance   Targeted for version 0.6
   
     * Allow 'declareModule()' to bootstrap non-existent modules; this might     * Functional/acceptance tests that access "real" databases, LDAP, etc.
       let us create "virtual packages" made by assembling other packages and  
       modules.  
   
     * Need a strategy for handling "del" operations; they are currently     * Get XMI writing in place, w/transaction support
       untrapped.  This might be okay under most circumstances, but need to  
       consider edge cases.  
   
     * 'makeClass()' should probably become part of the core API, where     * Generate UML 1.5 and CWM 1.0 and 1.1, and add them to the
       it can be used to resolve __metaclass__ conflicts during the first       'setup.py' package lists.
       pass of importing a module (prior to running 'setupModule()')  
   
      * On-the-fly class combination (think "runtime module inheritance",
        but possibly without the modules) for DMs.
   
   Messaging/ObjectSpaces     * Lock management interfaces/API for peak.storage
   
     * Support for sending and receiving remote cache invalidation      * Support for sending and receiving remote cache invalidation
       messages between DataManagers.        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.model  
   
     * 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?  
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   peak.metamodels.uml  
   
     * 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)
