Error description

  • During an IBM Rational ClearCase Unified Change Management (UCM)
    deliver, elements of type copy_merge will not be copied over if
    the file size and the checksum of the version element on both
    branches is the same.
    
    Steps to repro:
    1. Create a copy merge file type
       cleartool mkeltype -supertype compressed_file \
       -mergetype copy -nc FILE_COPY_MERGE
    
    2. cleartool chtype FILE_COPY_MERGE ?element?
    
    3. Check version number and note it.
    
    4. Check file size and make sure they are the same size.
    
    5. From dev stream, checkout and checkin identical.
    
    6. Deliver. Deliver will show a merge but no version will be
       created or merge arrow will be drawn.
    
    Workaround:
    Change file size or manually merge the files.

Comments

  • This is not a defect and is working as designed.
    
    As the contents of the file have not changed, there is no need f
    or a separate version, nor is a merge  arrow needed.
    
    A new version is always created in the development stream for ea
    ch checkin that we do on that stream, that doesn't mean or imply
     the creation of a new version after a deliver operation. A new
    version in the integration stream is only created when the new v
    ersion that is being merged is different in its contents than th
    e previous version existing in the integration stream. When a ne
    w version is created, a merge arrow is also drawn.
    
    A new version is also created and a merge arrow drawn, even if t
    he file size remains constant, given the fact that the contents
    of the file have changed.
    
    As for the message telling about a successful merge, that's used
     to convey a successful delivery and to specify that version rel
    ated information for the element was merged with internal CC rec
    ords.
