PI48224: CLEARCASE CHECKIN FAILS WITH SNAPSHOT VIEWS

IBM Rational Rhapsody 8.2.1

APAR status

• Closed as program error.

Error description

• Client runs a Rhapsody batch file called SensitiveCheckin.bat
  which
  calls cleardiff to compare the current and previous version of a
  checked out Rhapsody model unit to see if it should be
  checked-in or
  have the checkout cancelled.
  
  Customer reports this doesn't work with snapshot views.  It
  doesn't
  work because cleardiff doesn't support using version extended
  path
  names from snapshot views.
  

Local fix

• As a workaround, the customer has manually edited the
  SensitiveCheckin.bat to evaluate the return value of "cleartool
  diff
  -pred" instead of cleardiff.  The "cleartool diff -pred"
  ClearCase
  command works with snapshot views.
  
  According to ClearCase support:
  
  To re-cap, cleartool diff will definitely work in both dynamic
  and snapshot views.
  
  I did a little more research, and discovered a -status_only
  option that can be used with both cleardiff and with cleartool
  diff that provides an exit status about whether or not a
  difference is found.  Perhaps that is what the
  SensitiveCheckin.bat is using now with cleardiff.
  
  Here is an example of the basic cleartool diff syntax (though it
  doesn't actually capture the exit status in a variable)
  
  	cleartool diff -pred -options -status_only FileName
  
  Note: the reference page for the cleartool diff command at
  http://www-01.ibm.com/support/knowledgecenter/#!/SSSH27_8.0.1/co
  m.ibm.rational.clearcase.cc_ref.doc/topics/ct_diff.htm states
  about the -options argument, "For descriptions of the valid
  options, see the cleardiff reference page."  The cleardiff
  reference page at
  http://www-01.ibm.com/support/knowledgecenter/#!/SSSH27_8.0.1/co
  m.ibm.rational.clearcase.cc_ref.doc/topics/cleardiff.htm states,
  "â “status_only suppresses all output, returning only an exit
  status: a 0 status indicates that no differences were found; a 1
  status indicates that one or more differences were found. This
  option is useful in shell scripts." (all links are to ClearCase
  8.0.1 Information Center).
  
  I haven't used the -status_only option myself, but I thought I'd
  pass it along.

Problem conclusion

• As cleardiff -status_only it is not working on snapshot views.
  Updating SensetiveCheckin.bat  file with cleartool diff -pred
  -options -status_only which works with both snapshot and dynamic
  view.
