LynxKite changelog

Changelog History

Page 9

• v1.2.0 Changes

  • Graph visualizations are now cut to only show on the corresponding side. The previous behavior was especially disturbing when combined with map view.
  • The user registry file now has to be specified in .kiterc as KITE_USERS_FILE. Earlier versions used the user registry from kite_XXX/conf/users.txt. If you run LynxKite with authentication, please copy this file to a preferable location and add KITE_USERS_FILE to your .kiterc when upgrading.
  • Improvements in the configuration for number of cores per executor:
    • One common .kiterc option (NUM_CORES_PER_EXECUTOR) regardless of deployment mode
    • As a consequence, YARN_CORES_PER_EXECUTOR option has been removed. Please update .kiterc on YARN deployments by renaming YARN_CORES_PER_EXECUTOR to NUM_CORES_PER_EXECUTOR.
    • Use correcty the value of the above option internally to optimize calculations knowing the amount of cores available
    • In case of EC2, correctly set up this new kiterc option based on the cluster configuration
  • Fixed a bug that caused "hard" filtering to segmentations to fail.
  • Spaces in ACL lists are now ignored.
  • Error reports now go to [email protected] instead of [email protected].
  • Previously hidden utility operations (like "Delete vertex attribute") are now revealed on the interface. This is so that they can be accessed when editing the history.
  • Import and simple operations should now work even if there is insufficient memory to hold the entire graph.
  • New icons: triangle, pentagon, star, sim, radio.
  • File sizes are logged for import and upload. (This will be useful for troubleshooting.)
  • Operation search button. (This is the same as pressing /.)
  • Delimiters in load CSV operations now support standard java escapes. (Most importantly, you can import from a tab delimited file using \t as the value of the delimiter parameter.)
  • Project history (the list of operations that have been applied) can now be viewed and also edited. This is an experimental feature. Operations from earlier versions cannot be viewed or edited.
  • Fixed an issue with undo. The fix introduces an undo incompatibility. Operations from earlier versions cannot be undone after the upgrade.
  • Added a "Filter by attributes" operation. This is identical to filtering the usual way.
  • Regex filters can now be applied to string attributes. The syntax is regex(R) for example for finding strings that contain R. Or regex(^Ab) for strings that start with Ab. Or regex((.)\1) for strings with double letters. Etc.
  • Non-neighboring vertices are partially faded out when hovering over a vertex.
  • Fixed a leak in visualization that would gradually degrade performance in the sampled view.
  • In addition to scrolling, double-clicking and right double-clicking can be used now to zoom in and out. With Shift they adjust the thickness.
  • Upgraded to Apache Spark 1.3.0. Users need to download this and update SPARK_HOME in their .kiterc.
  • Fixed logout behavior on the splash page (/).

• v1.1.3 Changes

  • Fixed a bug with user creation.

• v1.1.2 Changes

  • Administrator users can now be created. Only administrators can create new users, and they have full access to all projects. Old user configuration files are incompatible with this change. If this is a problem, we can manually convert old user configuration files.
  • Add logout link at the bottom when authentication is enabled.

• v1.1.1 Changes

  • "Connect vertices on attribute" now takes two attributes as parameters and will connect A to B if the "source" attribute of A matches the "destination" attribute of B. Set the same attribute for both parameters to get the previous behavior.
  • Fixes a bug in edge visualizations (manifested as "java.util.NoSuchElementException: key not found: ...")

• v1.1.0 Changes

  • Authentication related UI is hidden when authentication is disabled.
  • Position (latitude + longitude) attributes can be visualized on a map. (The map is generated by Google Maps, but none of the graph data is sent to Google.)
  • New edge operation "Add reversed edges" which creates a symmetric graph.
  • When a project is hard filtered results are now saved to disk. Previously they behaved identically to soft filters that - correctly - only compute their results on the fly.
  • Edge attributes can be visualized as colors and labels in sampled mode.
  • Discovered an issue that prevents compatibility from 1.0.0 and 1.0.1. Fortunately they were never marked as stable, so we are not making a heroic effort to maintain compatibility.
  • Visualize attributes of the type (Double, Double) as vertex positions. Such attributes can be created from two Double attributes with the new "Vertex attributes to position" operation.

• v1.0.1 Changes

  • New setting in .kiterc: YARN_NUM_EXECUTORS can be used to specify the number of workers.
  • Added (better) workaround for https://issues.apache.org/jira/browse/SPARK-5102.
  • Select all vertices (up to 10,000) as center by setting * (star) as the center.
  • 3D graph visualization in concrete vertices view.

• v1.0.0 Changes

  • Adds label size as a new visualization option.
  • UI for selecting vertex attribute visualizations has changed as a preparation for adding more visualization options.
  • Export Vector type attributes as a semicolon-separated list.
  • Vertex ID is no longer displayed in the visualization by default. It is still accessible by setting the ID attribute as the label.
  • User management page at /#/users.
  • Added a check for Apache Spark version at startup. Must be 1.2.0.
  • Changed project data format to JSON. Projects from earlier versions are lost. Compatibility with future versions, however, is guaranteed.
  • Added error reporting option for the project list.
  • Cleared up confusion between edge graph/line graph/dual graph.
  • Started changelog.
