 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        - 'running.IProcessProxy' should use conditions/values instead of
           listeners, and related command/supervisor tools should also be ported
   
     - Make all API signatures start with context component        - Add tests for Twisted support
   
     - Finalize name for 'config.Application' - probably 'config.DefaultContext'        - Make it possible to adapt from condition->value, so deriving from conds
           can still work, and implement events.AllOf() as a condition
   
     - Review binding tutorial and correct any errors relative to current APIs        - Replace IMainLoop activity monitoring with a plugin-based mechanism?
   
     - Add 'fcgiapp' module sources to distribution; update README/INSTALL to credit      * peak.naming
       DC and OpenMarket and reference their licenses.  
   
         - 'ILoadingService', 'IObjectLoader' and 'load:kind@URL' scheme
   
       * peak.config
   
 Targeted for 0.5 Alpha 2        - "service zones" or "service groups" to do smarter service groupings
   
     * ZConfig Integration        - plugin keys ordered by definition sequence, rather than randomly
   
       - A 'config.ZConfig' module that provides "PEAK-aware" versions of ZConfig        - ZConfig factory support to allow "smart" interpretation of strings,
         services (e.g. it will use 'peak.naming' to resolve URLs)          section names, etc.
   
       - App startup tools based on ZConfig files.      * peak.running.logs
   
       - Sample 'AdaptiveTask' classes that perform the same functions as those in        - Separate formatters from publishers
         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        - ZConfig schema for logging plugins, allowing multiple handlers/category
   
     * Generate UML 1.4 and 1.5 and CWM 1.0 and 1.1, and add them to the      * peak.binding
       'setup.py' package lists.  
   
     * Get XMI writing in place, w/transaction support        - Cleanup/document attribute binding interface
   
     * 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      * peak.running.timers
        creating address syntaxes.  
   
         - Factor out state into separate object so timers aren't shared state
   
  Targeted for 0.5 Beta 1        - Look at possible integration of peak.query and cursor formatters, in
           order to view stats as an in-memory mini-DB w/reporting.
   
     * Updated reference docstrings for 'peak.api', 'peak.binding',      * peak.running
       'peak.config', 'peak.exceptions', and 'peak.naming'.  
   
     * Finish tutorial chapter 2 (?)         - Add "error formatting" and "error reporting" services
   
     * On-the-fly class combination (think "runtime module inheritance",      * peak.web (some of this may get bumped to alpha 4)
       without the modules) for DMs.  
   
          - clean up DOMlet parse/build framework (e.g. add line number info)
   
          - 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)

  Targeted for 0.5 Final Release (or sooner)   Targeted for 0.5 Alpha 4
   
     General      * Transaction/storage refactorings
   
         * Tutorial complete through chapter 4        - transaction scopes for commands and tasks
   
     peak.storage        - integrate locks with transactions
   
         - unit tests for more complex object scenarios: references, thunks..?        - transactable persistent queues
   
         - lock management interfaces/API        - DM.find()/DM.get() queries
   
         - docstrings for reference      * peak.running.commands
   
     peak.model         - Add option parsing framework based on optparse (backported to 2.2)
   
       * peak.config
   
          - Writable and subscribable config sources, including editable .ini's
   
         - clean up TW docstrings & interfaces      * 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
   
       * 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      peak.naming
   
         - useful example "flat" naming context (e.g. like AppUtils.URLkeys)          - useful example "flat" naming context (e.g. like AppUtils.URLkeys)
   
         - useful example hierarchical naming context (e.g. like JNDI's LDAP          - useful example hierarchical naming context (e.g. like JNDI's LDAP
           context or filesystem context)            context or a filesystem context)
   
         - rework smtp: to return a factory object that supports open().          - rework smtp: to return a factory object that supports open().
           Also think about whether smtp should move elsewhere. Maybe            Also think about whether smtp should move to peak.net?
           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 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.)
