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  46 If no out-of-date files are found, bringovercheck will produce no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