Greetings gatelings,
The change of copyrights in source code from Sun to Oracle that everyone
knew has been coming is finally almost here. For anyone pushing code
changes to the remainder of build 137: stay the course. But the first
push of build 138 next Tuesday will update the prototypes, the boot
banners,
/etc/motd and the tools to check for the new format, so anyone planning
changes for build 138 or later, below are the details on the new format.
The paradigm is that new files will be created with new copyrights, and
old files will be updated per the rules below when modified. But there
is no need to do pro-active updates; only update a file's copyright when
you are already modifying that file.
Please send any questions to .
1. When a new source file is created, it must contain the following
Oracle
copyright statement.
Copyright (c) YEAR, Oracle and/or its affiliates. All rights
reserved.
Where YEAR = the year in which the file is created.
Example:
Copyright (c) 2010, Oracle and/or its affiliates. All rights
reserved.
NOTE: Always use the "(c)" notation, even if the copyright
character is
available on your system, to avoid conflicts and confusion.
2. When an existing Sun source file is modified, the Sun copyright is
removed and replaced by an Oracle copyright:
Copyright (c) YEAR1, YEAR2, Oracle and/or its affiliates. All
rights reserved.
Where YEAR1 = one of the following options, in priority order:
a. The year in which the Sun file was created, if easily
determined.
Note: for ON, this is generally not easily determined; see
rule b.
b. The year in which the Sun file was introduced into the source
hierarchy, if easily determined. Note: for ON, this is easily
determined: run:
% /ws/onnv-gate/public/bin/start-date usr/src/foo usr/src/bar ...
c. The year listed in the Sun copyright currently in the file.
NOTE: For third-party code that was later modified by Sun and marked
with a Sun copyright, YEAR1 = the year in which the Sun copyright
was
introduced into the file, if easily determined. If not, use the
year
listed in the Sun copyright currently in the file.
Where YEAR2 = the latest year in which the file is modified.
Example:
Copyright (c) 1997, 2010, Oracle and/or its affiliates. All
rights reserved.
NOTE: If the year of creation and the year of modification are
the same,
use the notation outlined in #1 above. If EngineerA modifies a
Sun file
in 2010 that was created in 2010, EngineerA removes the Sun
copyright
and inserts an Oracle copyright that only contains a 2010 copyright:
Copyright (c) 2010, Oracle and/or its affiliates. All rights
reserved.
3. The instructions noted above also apply to "Portions Copyright YEAR,
Sun..." statements that are mostly used in manual pages.
Example:
Portions Copyright (c) YEAR, Sun Microsystems, Inc. All Rights
Reserved.
is replaced with:
Portions Copyright (c) YEAR1, YEAR2, Oracle and/or its
affiliates. All
rights reserved.
Where YEAR1 and YEAR2 are determined per the instructions in #2
above.
