InfoGrid 2.9.5 Released

It’s been a while since the last release, but why change if users are been generally happy with it ;-) … Here’s what’s new:

Highlights:

  • Native support for currency values (e.g. $1.23 USD)

  • Support for cascading delete
  • InfoGrid compilation is now reported to work on Windows
  • Multi-tenancy support for LID
  • More flexible handling of HTTP status codes in Probe framework (e.g. what should happen upon a redirect)
  • Extensions to custom JEE tags and HttpShell to make JSP programming with InfoGrid even simpler, e.g. simple tags to create Javascript-based overlay forms
  • Improved error reporting
  • Additional tests
  • Lots of small usability improvements and bug fixes

Here are the gory details:

  • tag to easily report a problem into the error log
  • tags to safeguard JSPs against inadvertent invocation by the wrong user or with the group user groups
  • support AccountStatus APPLIEDFOR and REFUSED

  • added MissingArgumentException that turns out to be generally useful
  • Created custom tags to help matching URL arguments easily
  • fixed incorrect processing of RuntimeException in HttpShell (particularly from HttpShellHandlers)
  • DataType would sometimes invalidly truncate HTML output with maxLength specified. Hope this implementation is better.
  • slight refactoring of JeeViewlet-internal API to make it easier to remove URL parameters from Viewlet’s default Post URL

InfoGrid 2.9.4 Released

This release contains some major improvements, in particular to the way the object graph is mapped to and from the web. Download or browse documentation here.

General:

  • improved stability and error reporting
  • lots of bug fixes
  • more tests
  • removed symbolic links from SVN; was an endless source of frustration

Core:

  • renamed TraversalDictionary to TraversalTranslator: it can be much more dynamic than a dictionary
  • implemented KeywordTraversalTranslator with fixed translation keywords
  • implemented XpathTraversalTranslator with a pseudo-subset of Xpath
  • introduced AllNeighborsTraversalSpecification instead of null TraversalSpecification; introduced StayRightHereTraversalSpecification
  • MeshObject’s userVisibleName now always returns value of a Property called “Name” if the MeshObject has one; this seems a sensible default for many applications
  • MeshObjectIdentifierFactory now has a pointer back to the MeshBase to which it belongs. Downside is one cannot use the same instance of MeshObjectIdentifierFactory for multiple MeshBases any more.
  • got rid of MeshStringRepresentationContext, which partially overlapped with the purpose of MeshStringRepresentationParameters; only historical reasons can explain why we had both
  • removed title/target/additionalParameters argument from HasStringRepresentation.toStringRepresentationLinkStart; now handled as parameters in StringRepresentationParameters
  • simplified StringRepresentation of PropertyValues and related
  • additional pre-defined StringRepresentations e.g. HttpPost
  • distinguish between formatting Properties (which may be null) and PropertyValues; no more muddling with funny MeshObject context parameters; formatting is now performed via DataType
  • use correct ClassLoader to load ResourceHelper default properties file during Module initialization
  • correct initialization of ResourceHelper in module.adv
  • expanded MeshObjectSet and MeshObjectSetFactory API

Identity-related:

  • refactored LID implementation to use an “instructions” based approach to the pipeline, instead of an exceptions-based approach. This is more flexible for users of the module.
  • fixed typo about credential vs. credtype.
  • renamed LidPersona to LidAccount; more natural to talk about it using that name
  • added LidAccountStatus and SiteIdentifier to LidAccount for multi-tenancy
  • factored account and session-related concepts from org.infogrid.lid.model.lid into new SubjectArea org.infogrid.lid.model.account.
  • new custom tag library that deals with identity

Model-related:

  • fixed code generation bug for descriptions of values in EnumeratedDataTypes
  • code generator to generate static constants for all EnumeratedValues.
  • added AccountCollection to account LID model
  • expanded TestModel to cover both optional and mandatory PropertyTypes; renamed PropertyTypes correspondingly
  • improved Test model for more comprehensive testing
  • better user-visible strings for EntityTypes Bookmark, Account and WebResource

Viewlet/GUI-related:

  • Viewlet framework and tag library extensions for including Viewlets in Viewlets; updated Viewlets accordingly; now allows in-context editing, change of viewlet types etc. for included JeeViewlets; no contiguous TraversalPath from top required
  • support REST-ful URLs on hierarchical Viewlets e.g. GraphTreeViewlet with multiple Viewlet alternatives in contained Viewlet
  • removed iframe in (Net)MeshWorld; hierarchical Viewlets is better approach
  • various HTML fixes and improvements related to the rendering and editing of PropertyValues
  • removed rootPath on all custom tags; not needed or used
  • sanitized formatting of Identifiers; it’s still not totally sane but a lot more so
  • eliminated PropertyValueTag.{css,js} and replaced with PropertyTag.{css,js}
  • removed -moz-opacity CSS value per recent Firefox updates
  • fix HTML doctype to make IE more happy
  • BlobViewlet to get its PropertyType from URL argument not POST argument
  • footer element for MeshObjectSetIterate tag
  • do not print iterateHeader and iterateFooter when set has no content in MeshObjectSetIterateTags
  • default POST behavior is now redirect-to-GET on same URL, so browser refresh is not as awful
  • added missing setter methods on StructuredResponse
  • created SetSizeTag to print the size of a MeshObjectSet in JSP
  • slight changes how MeshObjects are shown on screen by default (dropped annotation in which non-standard MeshBase they are)
  • overflow: auto; to support long CSS floats
  • added orderBy property to setIterate JSP tags
  • added ability to sort in the inverse direction
  • created propertymeter JSP tag for bar graphs or temperature graphs based on Properties
  • default sorting in JSP MeshObjectSet tags is by user-visible String
  • don’t set domains on cookies when run from localhost; makes life of developers hard
  • generate Javascript for PropertyValues
  • eliminating unnecessary projects by moving their code into other projects:
    • org.infogrid.jee.rest -> org.infogrid.jee.viewlet
    • org.infogrid.jee.rest.net -> org.infogrid.jee.viewlet.net
  • renaming projects:
  • org.infogrid.jee.rest.net.local -> org.infogrid.jee.viewlet.net.local
  • org.infogrid.jee.rest.net.local.store -> org.infogrid.jee.viewlet.net.local.store
  • org.infogrid.jee.rest.store -> org.infogrid.jee.viewlet.store
  • renamed meshObjectLoopVar to loopVar in custom tags
  • added arrivedAt property to Viewlet
  • enctype attribute on safeForm is all lowercase
  • created SaneUrl, new supertype of SaneRequest that allows to reuse API for URLs and servlet requests; slight API naming changes httpHost vs. server; allows us to get rid of OverridingSaneRequest nonsense
  • DEFAULT_LINK_START/END_ENTRY now consistently on StringRepresentation
  • removed RestfulRequest, replaced with a MeshObjectsToViewFactory that directly translates SaneRequest into MeshObjectsToView
  • an instance of MeshObjectsToViewFactory must now reside in Context
  • removed NetViewletDispatcherServlet; not needed any more
  • removed most redundant methods on Viewlet; better have one clear way how to do it only
  • upgraded ViewletFactoryChoice: now HasStringRepresentation and contains MeshObjectsToView; this means unfortunately that ViewletFactory setup in applications needs to pass MeshObjectsToView to their choices()
  • ViewedMeshObjects now keeps reference to MeshObjectsToView that it took its data from
  • removed unnecessary request attributes like JeeViewlet.VIEWLET_STATE_TRANSITION_NAME: can be obtained via Viewlet
  • made MeshObjectsToView an interface and subtyped to JeeMeshObjectsToView and NetMeshObjectsToView for cleaner model
  • renamed getMeshObjects to getViewedMeshObjects for consistency
  • ViewletState has moved from JeeViewlet to JeeViewedMeshObjects; added isDefaultState

FirstStepWithMySQL

Building on the recent InfoGrid FirstStep example, here is another: FirstStepWithMySQL.

Using the same bookmarking/tagging application as FirstStep, it shows how to persist the same MeshObjectGraph using MySQL as a key-value store. It consists of two apps:

  • the first app initializes the store, and creates a graph of objects
  • the second app retrieves the graph from the store, and traverses the graph to retrieve information.

It’s of course a trivial example, but it illustrates:

  • how easy it is in InfoGrid to keep the same application running against different storage backends with minimal code changes (in the initialization only)
  • some of the advantages of graph databases compared to other types of storage technologies: note how simple it is to traverse the graph in all directions.

Annotated source code is here.

InfoGrid 2.9.3 Released

Available for download here. This is mainly an incremental improvement/bug fix release, except:

  1. new capabilities in the ig-lid project related to what Randy Farmer called the tripartite identity pattern.
  2. new example application: FirstStepWithMySQL (see separate post).

Summary of changes:

  • fixed endless loop when Transaction open at MeshBase die time
  • Moved (Net)MeshObjectIdentifierFactory to .mesh.net packages. That allows is to tighten permissions a bit.
  • Check that localIds are at least 4 chars long. Not having this check created confusing results for users of MeshWorld where the GUI assumes this, but not the graph db.
  • Replaced StringRepresentationParseException with java.text.ParseException in most places.
  • More specific subclasses of LidInvalidCredentialException for better error reporting
  • More resilient when Gpg home dir cannot be created
  • Better TimeStampValue.toString()
  • Make it easier to create “su” Transactions with elevated privileges
  • collect all outgoing data into the same XprisoMessage; this prevents sending more than one message in response to a single incoming message
  • improved abilities to freshen Replicas
  • added ForwardReferenceTest9
  • added DelegatingNetMeshObjectIdentifierFactory as a convenience class
  • Major refactoring in module ig-lid to implement what Randy Farmer called the tripartite identity pattern. Nickname is what he calls Public ID. HasIdentifier is used to represent Login ID. LidPersona represents what he calls Account and also manages the relationships to the other items. There is a corresponding Model.
  • Added identifier-as-entered to LidAuthenticationStatus for better error reporting
  • Re-introduced LidPersona as a major concept
  • TransactionAction now carries a few member variables (MeshBase, MeshBaseLifecycleManager, MeshObjectIdentifierFactory) in order to make the writing of transactional code more concise
  • Split org.infogrid.probe.test into several test modules; makes it better manageable
  • removed a bunch of unnecessary files from ig-vendors; they only take up space and bandwidth
  • fixed multiple ModelBase bug
  • failed to load model under some circumstances when not running under the Module framework
  • added isIdentifiedBy method to org.infogrid.util.HasIdentifier
  • changed MeshObjectSet.contains( MeshObjectIdentifier ) to MeshObjectSet.contains( Identifier )
  • added FirstStepWithMySQL
  • localization for LidAbortProcessingPipelineException

InfoGrid 2.9.2 Released

InfoGrid 2.9.2 is focused on the new project layout of the code base. This new layout has also been documented on the wiki, starting with the front page and continuing to the projects page.

The new layout will make it easier for newcomers to find their way around InfoGrid, and to selectively include only those parts of InfoGrid required for a given application. It’s top-level structure is as follows:

Below, you find directories such as:

  • modules: contains the functionality of the project
  • tests: automated tests for the project
  • testapps: web applications testing the project
  • etc.

Enjoy!
