Mylyn Task List

Repository Task Data

Refactoring Objectives

  • Task Data Refactoring
    • Currently not nomalized
      • repository configuration options stored in same file
      • Configuration data is being updated upon load anyway
    • Presentation information such as hidden/readonly status fields being persisted (put with configuration?)
    • Operations being included
    • Task Data Externalization
      • Switch to XML
      • Possibly use IMemento
      • Separate files vs. one BIG file
      • Consider zipping all the individual xml files together into one zip file (similar to Open Office file format ODF)
  • Lazy loading
    • currently loaded at tasklist load time
    • Could just have a flag indicating the existence of an offline file rather than load the data
    • What does this break?

Proposed XML Serialization

<TaskData version="1.0" taskId="1" repositoryUrl="http://bugs.eclipse.org/bugs" repositoryKind="Bugzilla" modifiedTs="timestamp">
<Attribute id="...priority" modifiedTs="timestamp" author="rob.elves">
 <Value>xxx</Value>
 <Value>xxx</Value>
 <Value>xxx</Value>
</Attribute>
<Comment hasAttachment="true" attachmentId="1">
 <Attribute id="...author">
  <Value>rob.evles</Value>
 </Attribute> 
</Comment>
<NewComment>
   My new comment
</NewComment>
<Attachment id="1" isObsolete="false">
 <Attribute id="...attachment_date">
  <Value>date</Value>
 </Attribute>
</Attachment>
</TaskData>

Repository Configuration

Refactoring Objectives

    • (option 1) Leave as responsibility of connector assuming a contract:
      • Provide IMemento upon startup as an option?
      • Remote configuration gathered periodically
      • Always available (even if repository is deleted, configuration sticks)
      • Given a configuration folder within .mylar to persist data (not ideal)
      • Task data combined with configuration upon presentation rather than persistence
    • (option 2) XML externalization
      • Available options per id (ie. taskdata.priority --> P1, P2, P3...)
      • Available options given a specific product selection <Attribute id="taskdata.components"><Value>Bugzilla</Value><Value>Core</Value>
      • Hidden/readonly status for attributes?

Proposed XML Serialization

<RepositoryConfiguration>
<GeneralOptions id="...products" hidden="false" readonly="false">
 <Value>Mylar</Value>
 <Value>Nebula</Value>
</GeneralOptions>
<ProductOptions>
<Product name="Mylar">
  <Options id="....os">
    <Value>MacOS</Value>
    <Value default="true">Windows XP</Value>
  <Options>
 </Product>
</ProductOptions>
</RepositoryConfiguration>
