2.0

[zbateson]

Changes:

• Use pimple/pimple for di, refactor initialization:

  • Reconfigure the dependency container entirely, call MailMimePaser::setDependencyContainer
  • Add providers, call MailMimeParser::configureDependencyContainer with an
    array of providers

• Parser improvements:

  • modular parsing separated into classes for better extensibility
  • dynamic/proxied parsing based on user requests (looking at message headers
    won't parse all content/children and is therefore very very fast even on
    larger messages)
  • stream is no longer copied first, but must be closed after the
    message object is destroyed (or can be attached to the message)

• Define and use interfaces instead of concrete classes for better
  extensibility, change of internal hierarchy that didn't make sense

  • IMessagePart instead of MessagePart, IMimePart instead of MimePart,
    IUUEncodedPart instead of UUEncodedPart, IMultiPart is new, IMessage instead
    of Message. HeaderPart and ParentHeaderPart no longer exist.

• Remove deprecated resource handle methods:

  • Removes IMessage::getTextResourceHandle,
    IMessage::getHtmlResourceHandle
  • Removes IMessagePart::getContentResourceHandle

• Filtering parts is now done with simple callbacks. PartFilter is now just a
  convenience class with static methods that provides filtering callbacks
  instead of a concrete class used for filtering.

• Other minor changes of note:

  • MimePart::getContentDisposition for a MimePart is now limited to returning
    'inline' or 'attachment' even if the header has a different value.
  • IMultiPart::removeAllParts now returns the number of parts removed.
