|
* HISTORY
|
|
*
|
|
* 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
|
|
*
|
|
* Revision 1.16 92/09/09 22:04:51 mrt
|
|
* Really added bww's recvone changes this time.
|
|
* Added code to support non-crypting version of sup.
|
|
* [92/09/01 mrt]
|
|
*
|
|
* Revision 1.15 92/08/11 12:07:09 mrt
|
|
* Added support to add release to FILEWHEN name.
|
|
* Updated variable arguemnt list usage - bww
|
|
* Updated recvone() to take a va_list - bww
|
|
* Changed conditional for rpausing code from CMUCS to MACH
|
|
* [92/07/24 mrt]
|
|
*
|
|
* Revision 1.14 92/02/08 18:24:12 mja
|
|
* Only apply "keep" mode when local file is strictly newer
|
|
* otherwise allow update as before if necessary.
|
|
* [92/02/08 18:09:00 mja]
|
|
*
|
|
* Added support for -k (keep) option to needone(). Rewrote and
|
|
* commented other parts of needone().
|
|
* [92/01/17 vdelvecc]
|
|
*
|
|
* Revision 1.13 91/05/16 14:49:41 ern
|
|
* Add timestap to fileserver.
|
|
* Drop day of the week from 5 messages.
|
|
* [91/05/16 14:47:53 ern]
|
|
*
|
|
* Revision 1.12 89/08/23 14:55:44 gm0w
|
|
* Changed msgf routines to msg routines.
|
|
* [89/08/23 gm0w]
|
|
*
|
|
* Revision 1.11 89/08/03 19:49:10 mja
|
|
* Updated to use v*printf() in place of _doprnt().
|
|
* [89/04/19 mja]
|
|
*
|
|
* Revision 1.10 89/06/18 14:41:27 gm0w
|
|
* Fixed up some notify messages of errors to use "SUP:" prefix.
|
|
* [89/06/18 gm0w]
|
|
*
|
|
* Revision 1.9 89/06/10 15:12:17 gm0w
|
|
* Changed to always use rename to install targets. This breaks hard
|
|
* links and recreates those known to sup, other links will be orphaned.
|
|
* [89/06/10 gm0w]
|
|
*
|
|
* Revision 1.8 89/05/24 15:04:23 gm0w
|
|
* Added code to check for EINVAL from FSPARAM ioctl for disk
|
|
* space check failures when the ioctl is not implemented.
|
|
* [89/05/24 gm0w]
|
|
*
|
|
* Revision 1.7 89/01/16 18:22:28 gm0w
|
|
* Changed needone() to check that mode of files match before
|
|
* setting update if times also match.
|
|
* [89/01/16 gm0w]
|
|
*
|
|
* 10-Feb-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added timeout to backoff.
|
|
*
|
|
* 27-Dec-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added crosspatch support.
|
|
*
|
|
* 09-Sep-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added code to be less verbose when updating files that have
|
|
* already been successfully upgraded.
|
|
*
|
|
* 28-Jun-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added code for "release" support.
|
|
*
|
|
* 26-May-87 Doug Philips (dwp) at Carnegie-Mellon University
|
|
* Converted to end connection with more information.
|
|
* Added done routine. Modified goaway routine to free old
|
|
* goawayreason.
|
|
*
|
|
* 26-May-87 Doug Philips (dwp) at Carnegie-Mellon University
|
|
* Use computeBackoff from scm instead of doing it ourselves.
|
|
*
|
|
* 25-May-87 Doug Philips (dwp) at Carnegie-Mellon University
|
|
* Split off from sup.c and reindented goaway calls.
