Open Issues/To-Do Items |
| |
|
| Targeted for 0.5 Alpha 1 |
Targeted for 0.5 Alpha 3 |
| |
|
| |
* peak.events migration |
| |
|
| |
- 'running.IProcessProxy' should use conditions/values instead of |
| |
listeners |
| |
|
| |
- Implement basic 'events.ISelector' and 'IEventLoop' |
| |
|
| |
- 'UntwistedReactor' should use an 'events.ISelector' to implement |
| |
I/O functions, and 'IEventLoop' to implement 'run()' |
| |
|
| |
- Add 'events.twisted_support', with 'TwistedScheduler', |
| |
'TwistedSelector', and 'DeferredAsTaskSwitch' |
| |
|
| |
* peak.naming |
| |
|
| |
- 'ILoadingService', 'IObjectLoader' and 'load:kind@URL' scheme |
| |
|
| |
* peak.config |
| |
|
| |
- "service zones" or "service groups" to do smarter service groupings |
| |
|
| |
- plugin keys ordered by definition sequence, rather than randomly |
| |
|
| |
- ZConfig factory support to allow "smart" interpretation of strings, |
| |
section names, etc. |
| |
|
| |
* peak.running.logs |
| |
|
| |
- Separate formatters from publishers |
| |
|
| |
- ZConfig schema for logging plugins, allowing multiple handlers/category |
| |
|
| |
* 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. |
| |
|
| |
* peak.running |
| |
|
| |
- Add "error formatting" and "error reporting" services |
| |
|
| |
* peak.web (some of this may get bumped to alpha 4) |
| |
|
| |
- 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) |
| |
|
| |
|
| |
|
| |
|
| |
|
| * "Rule"-oriented configuration files (section specifies component rather |
|
| than property name prefix), w/support for chaining loader objects across |
|
| includes, and the ability to specify "Load on Demand" sections. |
|
| |
|
| * Review possible cross-locational or "root" things like |
|
| 'PropertyName' -- should these things move to the API? |
|
| Or where? They're not 'util' things, certainly. Perhaps |
|
| there should be a 'peak.core' module or package for things |
|
| that are foundational to all the packages? |
|
| |
|
| * Updated reference docstrings for 'peak.api', 'peak.binding', |
|
| 'peak.config', 'peak.exceptions', and 'peak.naming'. |
|
| |
|
| * Additional content for the tutorial's chapter on binding |
|
| |
|
| Targeted for 0.5 Final Release (or sooner) |
|
| |
|
| General |
|
| |
|
| * Update tutorial documentation |
|
| |
|
| * Up-to-date and complete Persistence package |
|

|
| w/SQL in error object |
|
| |

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.running.commands |
| |
|
| |

| |
|
| |

| |
|
| |
* 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 |
