Open Issues/To-Do Items |
| |
|
| Targeted for 0.2 Final Release |
Targeted for 0.5 Alpha 1 |
| |
|
| API.Modules |
* Fix issue w/reading XMI 1.1 files where metamodel has nested packages |
| |
|
| * Add tests for 'adviseModule()' API |
* Clean up __class_provides__ so that it isn't just something randomly |
| |
poked in by binding.Once(); it needs a clean infrastructure/interface. |
| |
|
| * Add checks and warnings for ambiguous re-assignments and operations |
* Refactor "Pythonic" UML 1.3 extensions so they're usable for most |
| on mutables (i.e. setting items or attrs), plus "safe" setattr |
MOF-aligned metamodels (e.g. all UML and CWM versions) |
| |
|
| Database |
* Remove deprecated items from peak.model: Feature, Reference, Package, |
| |
Model, Namespace, DataType, etc. |
| |
|
| * Create test suite to check proper transactional functioning, cache |
* Get XMI writing in place, w/transaction support |
| consistency, queueing behavior, and typemap management. |
|
| |
|
| * Update Interfaces to reflect current API, and document internals |
* Updated reference docstrings for 'peak.api', 'peak.binding', |
| |
'peak.config', 'peak.exceptions', and 'peak.naming'. |
| |
|
| |
* Finish tutorial chapter 2 (?) |
| |
|
| |
Targeted for 0.5 Alpha 2 |
| |
|
| |
* On-the-fly class combination (think "runtime module inheritance", |
| |
without the modules) for DMs. |
| |
|
| |
* ZConfig support, probably in the form of generating ZConfig schemas |
| |
from 'peak.model' or MOF models, but maybe in the form of 'fromZConfig' |
| |
constructor methods as well. |
| |
|
| |
* 'peak.running' refactorings: use standard 'logging' module's log levels, |
| |
add 'logging' distro to 'peak.util' for 2.2 backward compatibility, |
| |
make daemons based on 'peak.model' (or at least define ZConfig schemas), |
| |
and possibly adjust cluster stuff to work off ZConfig primary and |
| |
generate clustertools file(s). App startup tools based on ZConfig and |
| |
PEAK-style .ini files. |
| |
|
| |
* 'peak.naming' refactorings: 'peak.model'-based syntax utilities for |
| |
creating address syntaxes. |
| |
|
| |
Targeted for 0.5 Final Release (or sooner) |
| |
|
| General |
General |
| |
|
| * Update tutorial documentation |
* 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? |

| Ideas for 0.3 Release |
|
| |
|
| Dispatching |
|
| |
|
| * Virtual features to implement retrieving the other end of a |
|
| relationship from another Specialist. |
|
| |
|
| SEF |
|
| |
|
| * Persistent SEF module, with Base.__getstate__ supporting omission |
|
| of Once attributes, and DynamicBinding setting _p_changed on |
|
| instantiation. |
|
| |
|
| * A way to generate Z3 Interfaces from Feature-based specifications? |
|
| |
|
| |
|
| Database |
|
| |
|
| * Rack-like object to do persistent storage of Elements? |
|
| |
|
| |
|
| General |
|
| |
|
| * Profiling and performance tuning of module inheritance and other |
|
| core features of API and SEF. |

* Support for sending and receiving remote cache invalidation |
| |
messages between RecordManagers. |
| |
|
| * Include dependencies in packaging? Need to ask copyright owners first. |

|
| SEF |
|
| |
|
| * Review other-end-notification protocols in the light of managed storage |
|
| models (e.g. database Records using virtual sequence objects as fields) |
|
| |
|
| * Marshalling interface in Services; implementations for Enumeration, etc. |
|
| |
|
| * More S-E-F metadata: features, subclasses, svc.<->class, nested services |
|
| |
|
| * Implement WarpCORE-oriented structural model, w/Querying support |
|
| |
|
| InMemory |
|
| |
|
| * "Indexed" version |
peak.model |
| |
|
| * "WeakRefs" version (no acquisition, use w/Python 2.1 weakrefs) |
* Implement WarpCORE-oriented structural model, w/Querying support |
| |
|
| * "Circular" version (suitable for use w/2.1 GC or Jython) |
* "Indexed" version of in-memory model? |

|
| UML |
|
| |
|
| * Need to write an MMX or XMI -> Python generator, and hook it back up into |
|
| the UML package, since we're right now relying on a module generated |
|
| by code that depends on stuff which is going away. |
|
| |
|
| * 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) |
|
| |
|
| * Reporting mixins? Graphviz visualization? |

(class-scope) methods/attributes? |

|
| * Strict parsing and/or diagnostics on files that don't match the metamodel? |
- Are association-ends scoped? |
| |
|
| * UUID/GUID support |
- Would it be better to seperate them? |
| |
|
| * Support for advanced references, external references? |
- What determines whether an implemented Service actually stores objects |
| |
or delegates this to its subclass services? |
| |
|
| * XML Namespaces (do any current XMI tools need this? Which spec version |
* Simple Zope product demo (upload XMI, then browse the model via the web) |
| requires this?) |
|
| |
|
| * DOM StructuralModel (so files can be edited without affecting vendor XMI |
|
| extensions) |
