Error description

  • When a new 3 digit hook ID of format 0NN is added,
    the undo file that is generated is incorrect.
    ....  example ..............
    * /etc/trcfmt
    + 0E1 1.0 '@ MY NEW HOOK: Trace Events' \
    $HD, \
    2 { 'MY-COMP func1 field1=$D1 field2=$D2'}, \
    3 { 'MY-COMP func2 field1=$D1 field2=$D2'}, \
    \* {0E1 unknown subhook: subhook=$HD D1=$D1 D2=$D2}
    .... end ....
    
    This should create an undo file.
    ... start ....
    * /etc/trcfmt
    - 0E10
    ............. end .....
    
    This incorrectly creates an unfo file
    
    * /etc/trcfmt
    - E10
    
    Thus failing the undo operation.
    

Local fix

  • The undo file can be manually edited to add a "0".
    

Problem summary

  • Customer is not able to generate prpoer undo file
    when a new 4 digit hook ID of format 0NNN is added.
    

Problem conclusion

  • The traceid string which will be present in the trc file will
    be directly copied to undo.trc file instead of converting
    traceid string to integer and again back from integer to
    string and placing it in undo.trc file.
    

Temporary fix
