APAR status

• Closed as program error.

Error description

• On UNIX and Linux, most client actions in an IBM Rational
  ClearCase view are limited by the filename and pathname lengths
  allowed by the host operating system and filesystem format.
  Another limitation is the total of 1024 characters in a
  version-extended path, as described in technote 1150854
  (http://www-01.ibm.com/support/docview.wss?uid=swg21150854 About
  the maximum character length of a version extended path).
  
  When the view storage path on UNIX or Linux approaches 255
  characters, the view/VOB extended path may cause problems with
  element operations such as checkout.
  
  [user@cchost1 ~]# cleartool mkview -tag abc
  /tmp/abcdefghijklmnopqrstuvwxyz/abcdefghijklmnopqrstuvwxyz/abcde
  fghijklmnopqrstuvwxyz/abcdefghijklmnopqrstuvwxyz/abcdefghijklmno
  pqrstuvwxyz/abcdefghijklmnopqrstuvwxyz/abcdefghijklmnopqrstuvwxy
  z/abcdefghijklmnopqrstuvwxyz/abcdefghijklmnopqrstuvwxyz/abc.vws
  (247 chars)
  
  [user@cchost1 ~]# cleartool mount /vobs/vob1
  [user@cchost1 ~]# cd /vobs/vob1/a
  [user@cchost1 a]# cleartool setview abc
  
  [user@cchost1 a]# cleartool checkout -nc .
  cleartool: Error: Unable to determine absolute pathname for '.'
  - Device not a stream
  cleartool: Warning: Checked-out version is not selected by view.
  Checked out '.' from version '/main/4'.
  
  The following errors will be logged on the view server:
  
  VIEW LOG:
  See vobrpc_server_log on host cchost1
  2012-11-09T17:17:04-05:00 view_server(11928): Error: Unexpected
  error in VOB 'cchost1:/vobstore/vob1.vbs' op
  vob_obj_get_view_info(0x30):File name too long
  
  VOBRPC LOG:
  2012-11-09T17:17:04-05:00 vobrpc_server(11938): Error: INTERNAL
  ERROR detected and logged in
  '/var/adm/rational/clearcase/log/error_log'.
  
  ERROR LOG:
  vobrpc_server(11938): Ok: Internal Error detected in
  '/vobs/atria/lib/vob/ob.c' line 161
  vobrpc_server(11938): Error: String buffer too small.
  
  Steps to reproduce:
  1. Create a view with a path so long that adding the path to the
  element in the VOB will exceed 255 characters
  2. Check out the element
  
  Workaround: Shorten the path to view storage as needed.

  ****************************************************************
  When the view storage path on a ClearCase Unix or Linux
  system approached 255 characters in total length, some
  operations such as checkout could fail, even though the
  user-visible view tag and VOB tag are short enough for fully
  qualified pathnames to be within supported limits.
  

Problem conclusion

• This problem is fixed in ClearCase 8.0.0.9 and 8.0.1.2.
