* HISTORY
|
|
* 13-Sep-92 Mary Thompson (mrt) at Carnegie-Mellon University
|
|
* Changed name of DEFDIR from /usr/cs to /usr.
|
|
*
|
|
* 7-July-93 Nate Williams at Montana State University
|
|
* Modified SUP to use gzip based compression when sending files
|
|
* across the network to save BandWidth
|
|
*
|
|
* $Log: sup.h,v $
|
|
* Revision 1.3 1995/06/03 21:21:54 christos
|
|
* Changes to write ascii timestamps in the when files.
|
|
* Looked into making it 64 bit clean, but it is hopeless.
|
|
* Added little program to convert from the old timestamp files
|
|
* into the new ones.
|
|
*
|
|
* Revision 1.2 1993/08/04 17:46:15 brezak
|
|
* Changes from nate for gzip'ed sup
|
|
*
|
|
* Revision 1.1.1.1 1993/05/21 14:52:18 cgd
|
|
* initial import of CMU's SUP to NetBSD
|
|
*
|
|
* Revision 1.10 92/08/11 12:06:42 mrt
|
|
* Added definition for DEBUGFPORTNUM, the debugging port number.
|
|
* Changed so that last and when file names could include
|
|
* the relase name if any.
|
|
* [92/07/23 mrt]
|
|
*
|
|
* Revision 1.9 91/04/29 14:39:03 mja
|
|
* Reduce MAXCHILDREN from 8 to 3.
|
|
*
|
|
* Revision 1.8 89/08/23 14:55:30 gm0w
|
|
* Moved coll.dir from supservers to supfiles.
|
|
* [89/08/23 gm0w]
|
|
*
|
|
* 18-Mar-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added host=<hostfile> support to releases file.
|
|
*
|
|
* 27-Dec-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added crosspatch support. Removed nameserver support.
|
|
*
|
|
* 27-Jun-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added TREELIST and other changes for "release" support.
|
|
*
|
|
* 25-May-87 Doug Philips (dwp) at Carnegie-Mellon University
|
|
* Version 6 of the network protocol, better support to reflect errors
|
|
* back to server logfile.
|
|
*
|
|
* 21-May-87 Chriss Stephens (chriss) at Carnegie Mellon University
|
|
* Merged divergent CS and EE versions.
|
|
*
|
|
* 19-Sep-86 Mike Accetta (mja) at Carnegie-Mellon University
|
|
* Added FILESUPTDEFAULT definition.
|
|
*
|
|
* 07-Jun-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Removed FILESRVBUSYWAIT. Now uses exponential backoff.
|
|
*
|
|
* 30-May-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added numeric port numbers to use when port names are not in the
|
|
* host table.
|
|
*
|
|
* 04-Jan-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Update protocol version to 5 for name server protocol change to
|
|
* allow multiple repositories per collection. Added FILESRVBUSYWAIT
|
|
* of 5 minutes. Added FILELOCK file to indicate collections that
|
|
* should be exclusively locked when upgraded.
|
|
*
|
|
* 22-Sep-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Merged 4.1 and 4.2 versions together.
|
|
*
|
|
* 04-Jun-85 Steven Shafer (sas) at Carnegie-Mellon University
|
|
* Created for 4.2 BSD.
