670.0. "Modification to Lib$fid_to_name, what is it?" by AIMTEC::SIMPSON_L () Mon Jun 02 1997 16:55

    Hello!
    
    I see in looking at the description of the Eco kit Vaxlibr06_070 that
    some problem fixes were included in it from other Eco kits.  The one
    I'm concerned with is the problem fix incorporated which came from the
    Eco kit Vaxlibr01_070 originally.  This was a modification to
    Lib$fid_to_name.  What the fix statement says is:
    
    	o  Liv$fid_to_name has been modified to ensure that the use of very
    deep directory trees do not result in the call stack being corrupted.
    
    I have a customer who installed the Vaxlibr06_070 because of the
    Delta-time issue but also because he was told that this modification of
    Lib$fid_to_name would resolve his problems with directory trees.  He is
    still experiencing problems with directory trees which are 8 levels
    deep.  
    I'm not sure as to what the problems are.  He could not be clear with
    me on this.  Didn't seem to know exactly what the problems were, just
    that there were problems.
    
    What is the modification to Lib$fid_to_name exactly supposed to
    correct?  I'd like to understand this better so I can explain it to the
    customer and see if we can clarify whether this will help him or not.
    
    Thanks very much!

   You'll need to acquire further information -- code examples, error
   messages, etc, -- on the problems being encountered.  (This sounds
   like the customer might be `fishing' for further information on the
   topic of deep directories.)
670.2this ECO does NOT remove the 8-level directory limitationFRSTSC::TLAUER"I've been designed multi-asking."Tue Jun 03 1997 05:237
Just in case your customer expects this ECO to remove the 8-level directory
limit... This is not the case!! It's a real bugfix removing some stack
corruption problems within that routine, and it's not removing the RMS design
limitation of a file specification being capable of holding up to 8 directory
levels.
