APAR status

• Closed as program error.

Error description

• When a full labeled baseline labels multiple versions of the
  same element (an invalid situation)
  then making a new baseline with this as 'backstop' fails with
  the messages:
  
  ?chbl ...
  Begin incrementally labeling baseline
  'LABEL_Integration_110617'.
  (cleartool: Warning: Possible stranded temporary lbtype name
  found: 'LABEL_Integration_110617_in_progress'.)
  cleartool: Error: Error incrementally labeling baseline
  'LABEL_Integration_110617'.
  cleartool: Error: Some baselines could not be labeled.
  
  It SHOULD fail with:
  
  ?chbl ...
  Begin incrementally labeling baseline
  'LABEL_Integration_110617'.
  (cleartool: Warning: Possible stranded temporary lbtype name
  found: 'LABEL_Integration_110617_in_progress'.)
  cleartool: Error: More than one version with label of type
  'LABEL_Integration_110617'.
  cleartool: Error: Error incrementally labeling baseline
  'LABEL_Integration_110617'.
  cleartool: Error: Some baselines could not be labeled.
  
  
  Steps to Reproduce:
  
  NOTE: This situation could arise only as a result of some other
  defect, or by
        following the following steps to emulate such a defect.
  
  Put a predecessor baseline label on two versions of an element
  to be labeled.
  ?cleartool mklbtype -replace -pbranch
  LABEL_Integration_110616@\CVOB
  ?cleartool mklabel -nc LABEL_Integration_110616_Docs
  \CVOB\Docs\foo.doc@@\main\0
  ?cleartool mkbl -component Docs@\PVOB
  
  
  Workaround:
  
  N/A
  Workaround of actually having the 'ambiguously labeled element'
  situation is to identify the element
  and remove the label from one of the versions.
  To do this the folowing commands are useful:
  cleartool find -all -version 'lbtype(PRED_FULL_LABEL)' -print ?
  find-version.log
  cleartool find -all -element 'lbtype_sub(PRED_FULL_LABEL)'
  -print ? find-element.log

  Problem Description:
  ===============
  When a full labeled baseline labels multiple versions of the
  same element (an invalid situation)
  then making a new baseline with this as "backstop" fails
  with the messages:
  
  ?chbl ...
  Begin incrementally labeling baseline
  "LABEL_Integration_110617".
  (cleartool: Warning: Possible stranded temporary lbtype name
  found: "LABEL_Integration_110617_in_progress".)
  cleartool: Error: Error incrementally labeling baseline
  "LABEL_Integration_110617".
  cleartool: Error: Some baselines could not be labeled.
  
  It SHOULD fail with:
  
  ?chbl ...
  Begin incrementally labeling baseline
  "LABEL_Integration_110617".
  (cleartool: Warning: Possible stranded temporary lbtype name
  found: "LABEL_Integration_110617_in_progress".)
  cleartool: Error: More than one version with label of type
  "LABEL_Integration_110617".
  cleartool: Error: Error incrementally labeling baseline
  "LABEL_Integration_110617".
  cleartool: Error: Some baselines could not be labeled.
  
  Solution Description:
  =============
  There were some unnecessary checks being performed to print
  the message.
  Removed the unnecessary check and the message gets printed
  now.
  

Problem conclusion

• A fix is available in ClearCase versions 7.1.2.7 and 8.0.0.3
