* HISTORY
|
|
* Revision 1.8 92/08/11 12:04:28 mrt
|
|
* Brad's changes: delinted, added forward declarations of static
|
|
* functions.Added Copyright.
|
|
* [92/07/24 mrt]
|
|
*
|
|
* 18-Mar-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added host=<hostfile> support to releases file.
|
|
*
|
|
* 11-Mar-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added "rsymlink" recursive symbolic link quoting directive.
|
|
*
|
|
* 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
|
|
* Lets see if we'll be able to write the scan file BEFORE
|
|
* we collect the data for it. Include sys/file.h and use
|
|
* new definitions for access check codes.
|
|
*
|
|
* 20-May-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added type casting information for lint.
|
|
*
|
|
* 21-Jan-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added check for newonly upgrade when lasttime is the same as
|
|
* scantime. This will save us the trouble of parsing the scanfile
|
|
* when the client has successfully received everything in the
|
|
* scanfile already.
|
|
*
|
|
* 16-Jan-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Clear Texec pointers in execT so that Tfree of execT will not
|
|
* free command trees associated with files in listT.
|
|
*
|
|
* 06-Jan-86 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added code to omit scanned files from list if we want new files
|
|
* only and they are old.
|
|
*
|
|
* 29-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Major rewrite for protocol version 4. Added version numbers to
|
|
* scan file. Also added mode of file in addition to flags.
|
|
* Execute commands are now immediately after file information.
|
|
*
|
|
* 13-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added comments to list file format.
|
|
*
|
|
* 08-Dec-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Added code to implement omitany. Currently doesn't know about
|
|
* {a,b,c} patterns.
|
|
*
|
|
* 07-Oct-85 Glenn Marcy (gm0w) at Carnegie-Mellon University
|
|
* Created.
