BRINGOVERCHECK 1ONBLD "Apr 7, 2006"
NAME
bringovercheck - Repair misordered workspace timestamps
SYNOPSIS
bringovercheck workspace
DESCRIPTION
Some versions of bringover(1ONBLD) fail to msync(2) writeable mappings; this results in indeterminate modification times when the workspace exists on certain filesystems. When this results in SCCS s. files being newer than their respective checked-out source files, build carnage may result (see sccscheck(1ONBLD) for one mitigating step being taken). If a workspace has been damaged by this bug, you can run bringovercheck to detect and correct cases where a source file is older than its corresponding SCCS s. file. If no out-of-date files are found, bringovercheck will produce no output; otherwise, it will produce a human-readable transcript which includes filenames, last modification dates, and the output of the sccs commands it uses to attempt to fix the problem. Note that because the problem may involve deferred filesystem writes, this script may not be fully effective if run immediately after a bringover.
