[GitHub] [iotdb] Cpaulyz opened a new pull request, #7943: [IOTDB-4876] Fix PathPatternTree missing information on subpaths

[GitBox <gi...@apache.org>]

Cpaulyz opened a new pull request, #7943:
URL: https://github.com/apache/iotdb/pull/7943

   ## Description
   
   ### BUG description
    After appending root.sg.d and root.sg.d.** to an empty pathPatternTree and invoking constructTree(), only root.sg.d.** can be taken by invoking getAllPathPatterns() and root.sg.d is missing.
   
   ### Solution
   In the original design, only the leaf nodes on the PathPatternTree are considered as measurement. However, the information is lost when there is a subpath for measurement. e.g. root->sg->d(measurement)->**(measurement).
   
   So we use an additional roleType field to identify whether the node in the tree is internal or measurement.
   
   To avoid compatibility problema, new semantics are given to the original valueSet field in the serialization method.
