  25 .TH bringovercheck 1 "7 April 2006"
  26 .SH NAME
  27 .I bringovercheck
  28 \- Repair misordered workspace timestamps
  29 .SH SYNOPSIS
  30 .B bringovercheck
  31 workspace
  32 .SH DESCRIPTION
  33 Some versions of 
  34 .I bringover(1) 
  35 fail to 
  36 .I msync(2)
  37 writeable mappings; this results in indeterminate modification times
  38 when the workspace exists on certain filesystems.  When this results
  39 in SCCS s. files being newer than their respective checked-out source
  40 files, build carnage may result (see
  41 .I sccscheck(1)
  42 for one mitigating step being taken).
  43 
  44 If a workspace has been damaged by this bug, you can run
  45 bringovercheck to detect and correct cases where a source file is
  46 older than its corresponding SCCS s. file.
  47 
  48 If no out-of-date files are found, bringovercheck will produce no
  49 output; otherwise, it will produce a human-readable transcript
  50 which includes filenames, last modification dates, and the output of
  51 the sccs commands it uses to attempt to fix the problem.
  52 
  53 Note that because the problem may involve deferred filesystem writes,
  54 this script may not be fully effective if run immediately after a
  55 bringover.
