      Description



      Name: kbR10066 Date: 01/15/2003


      It is a usual situation when a profiled app is run against a series of tests.
      And each time a test finishes, current coverage file is read from disk,
      merged with in-memory coverage an stored back to disk. This is either
      done by JVMPI agent, instrumented app, or even by running a separate
      merger command (especially when the test scales are needed).

      This operation (merging) can be very time-consuming, espesially in case
      of large coverage file. So it would be a good idea to implement a kind of
      a "merge server" which would recieve data via a socket, and merge it
      right in the memory. This scheme would eliminate:
      1. Reading entire jcov file from disk
      2. Parsing jcov file
      3. Writing jcov file to disk (this would be done only once)
      therefore significantly increasing testrun performance.
