SUBTTL Edit history
; RCOMP edit History
;
; 1 Initial subroutine to do recomputes for PLRDSK.
;
; 2 Add super mode input to read ribs to speed up things.
;
; 3 Routine FINISH wasn't calling the user supplied typeout subroutine.
;
; 4 Append STR:[PPN] to errors generated by ERRPRC.
;
; 5 Remove extra instruction in routine LOKUFD.
;
; 6 Add routines for search list manipulation and UFD creation.
;
;
; UFDSET edit history
;
;
; 7 Create UFDSET from the remains of RCOMP.
;
; 10 Remove edit 4, it was a bad idea. Enhance text generation code.
;
; 11 Fix bugs in single access code. Remove error code UFCSU% (Can't
; set UFD interlock) and issue a warning instead. We can't wait for
; the interlock since PULSAR shouldn't block. If a program really needs
; this functionality, it should handle the interlock itself and lite
; the UF.NLK bit.
;
; 12 Add functions .UFDASL and .UFRSL plus about a dozen lines of code
; to handle system search list changes.
;
; 13 Fix obscrure PATH block pointer problem caused by 702.
;
; 14 Make sure the job and PPN match for MOUNT and DISMOUNT functions.
;
; 15 Fix off-by-one bug in S/L definition size that showed up only when
; a user dismounted a disk when his S/L was full.
;
; 16 Release any open channels after processing errors at ERRPRC.
;
; 17 Close off UFD channel if create fails to find a UFD.
;
; 20 Don't try to use a released channel when creating UFDs.
;
; 21 Fix up quota checking for zero block logged out quotas.
;
; 22 Enhancementes required for use in LOGIN:
; 1) Clear RP.ERR in the UFD if no error bits found in file RIBs
; during recomputing pass.
; 2) Add functions .UFAJL and .UFRJL to only add and remove structures
; from a job search list. Needed for the SWITCH.INI handling.
; 3) Add functions .UFSUI and .UFCUI to set and clear the UFD interlock.
; 4) Set current date/time in the RIB and return it in .UFCDT
; and .UFCTM words.
;
; 23 Move 'File errors exist' message to the rename code, so if a recomp
; is done and no errors exist, the message won't be generated. Also
; setup PATH block before attempting to a super I/O LOOKUP. This will
; allow the correct filespec typeout to occur if file errors exist.
;
; 24 Clear out LKPFIL @SETFIL to prevent junk dates, protections, etc.
; from being set on ENTERs.
;
; 25 Some files don't get quota checked. MOVX instead of a MOVE.
;
; 26 Fix bad test that allowed anyone to dismount a structure, even
; if they were over quota.
;
; 27 RIBUSD can be zero for a non-empty UFD if the monitor hasn't
; rewritten the RIB yet. Don't blindly try to delete a UFD
; without first doing a DISK. UUO to see if the monitor really
; knows the number of blocks used.
;
; 30 Correct check of "own" job number and fix off by one bug in
; GOBSTR loop when searching for other jobs in the recomp checking
; code. Give UFDSET a real version number too.
;
; 31 Function .UFRDU forgot to LOOKUP the UFD.
;
; 32 Files of the form nnnTEC.TMP print incorrectly.
;
; 33 Fix incorrect block number calculation when doing super I/O on a
; unit whose cluster size does not divide evenly into the unit size.
;
; 34 Correct test for blocks in use before attempting to delete a UFD
; on a dismount.
;
; 35 Only change RIBUSD when recomputing disk usage.
;
; 36 Avoid RENAME error 26 by renaming the UFD before defining the
; search list which could set the structure status to NOWRITE.
;
; 37 A job can go over quota if we mount a structure which is already
; in the job's search list because the previous value in RIBUSD
; gets written back into the RIB instead of the actual number of
; blocks in use. Check UFBTAL.
;
; 40 Do Copyrights.
;
; 41 Add support for UFD operation on not logged-in UFDs. Needed to
; make MX work correctly. This also makes UFDSET usable by SPRINT
; if we ever get ambitious.
;
; 42 If there is another job with the same PPN and the same structure
; in its search list, then don't do quota checking, always set
; RIPLOG in the UFD, and never delete the UFD.
;
; 43 Be more graceful about UFD interlock handling. If we can't get the
; interlock, sleep for a while, then try again. Add parameters LOKINT
; to hold the interval between retries, and LOKLIM as the number of
; minutes to keep retrying for the interlock.
