- I'm pretty sure this didn't make it out because of our power failure.
- If it did, sorry for the repost; if it didn't, here it is! 8-)

-
- The Supervisor Series v5.3 has just been released. The Supervisor
- Series consists of SUPERVISOR (watch another user's terminal and enter
- input on their behalf) and PHOTO (record terminal sessions to a log
- file). Access to the SUPERVISOR functions is controlled through the
- use of identifiers.
-
- This version fixes two pretty major bugs in v5.2 (additional info can
- be found below my sig):
-
- o The "invalid log file" hang/crash with PHOTO
-
- o The SUPERVISOR "it's not a UCB anymore" crash
-
- NOTE: PHOTO is incompatible with VMS POSIX. THIS VERSION DOES NOT
- CORRECT THIS PROBLEM. The problem is that when POSIX has been
- started on the system, a system-wide image rundown handler
- resets the modified UCB fields, effectively turning off PHOTO.
- I hope to have this corrected in a future version of the series.
-
- I also found out that the original authors of the Supervisor Series
- were Bob Pasker, Bill Donner, and Terry Way. My thanks to them for
- providing me with a good base to work from.

- **** It will be posted to vmsnet.sources soon ****
-
- The Supervisor Series is available via anonymous ftp from ftp.spc.edu
- ([192.107.46.27]). You'll need the following files:
-

-
- To get the Supervisor Series via e-mail, send the following commands
- in the body of a message to FILESERV@WKUVX1.BITNET:
-
- SEND SUPERVISOR
- SEND FILESERV_TOOLS
-
- The Supervisor Series is installed with VMSINSTAL and includes
- documentation in ASCII text, Bookreader, and PostScript formats.
- There is a mailing list to discuss Supervisor Series problems and
- usage. To subscribe, send the following command in the body of a
- mail message to LISTSERV@WKUVX1.BITNET (note, that's LISTSERV):
-
- SUBSCRIBE SUPSER-L "Your real name"

-
- Thanks for your patience while I found the time to fix these!

- "Bug Fixes" (from the release notes):
-
- The Supervisor Series V5.3 provides the following bug
- fixes and enhancements to V5.2:
-
- 1 If an invalid log file was specified to PHOTO, the
- system would hang when the user logged out (SMP
- machines would crash with a SPINWAIT bugcheck).
- This problem occurred because PHOTO didn't clean up
- after itself properly if an error occurred during
- initialization. Not only has this bug been fixed,
- but the initialization was reorganized to make it
- safer.
-
- 2 SUPERVISOR would occasionally crash the system
- trying to access an LT UCB that had already been
- deleted. SUPERVISOR now checks to make sure the UCB
- is still a UCB before accessing it.
-
- 3 Privilege checks were added to SUPERVISOR so that
- the user is notified of the missing privileges
- immediately (the user only sees which privileges
- are missing if he/she holds one of the appropriate
- SUPERVISOR identifiers). This eliminates potential
- problems with privilege-related errors occurring
- during initialization.
-
- 4 A bug in the SUPERVISOR exit handler would cause
- a non-fatal register dump if SUPERVISOR aborted
- during the initialization. This bug has been
- corrected.
-
- 5 SUPERVISOR notifications to the target user would
- hang the supervising terminal if the target user
- had XOFF'ed or switched sessions on a DECserver.
- The $BRKTHRUW call in SUPERVISOR has been modified
- to timeout after 5 seconds to prevent such hangs.
-
- 6 The installation now uses the specified PHOTO help
- library as the default help library for SUPERVISOR.
