Final Release Note

Description

Issue 1)

$VIEW("STATSHARE") changes from 0 to 1 after a region-specific VIEW "NOSTATSHARE" command

YDB>w $view("statshare")
0
YDB>view "nostatshare":"DEFAULT"
YDB>w $view("statshare")
1

In this case it should still be 0.

Issue 2)

Newly opened regions implicitly share even after a region-specific VIEW "NOSTATSHARE" or VIEW "STATSHARE" command whereas the release note for GTM-8874 clearly states that "after a VIEW specifies selective sharing, regions don't implicitly share as they open". Below is a test case that demonstrates the issue.

YDB>write $view("STATSHARE")
0
YDB>view "nostatshare":"AREG"
YDB>zsy "ls -l /proc/"_$j_"/fd"
total 0

Issue 3)

$VIEW("STATSHARE") should differentiate whether most recent VIEW "STATSHARE" or VIEW "NOSTATSHARE" command had region list or not.

Currently $VIEW("STATSHARE") returns 1 if the most recent VIEW "STATSHARE" or VIEW "NOSTATSHARE" command was either a VIEW "STATSHARE" or VIEW "STATSHARE":reglist or VIEW "NOSTATSHARE":reglist. The only reason when $VIEW("STATSHARE") returns 0 is if the most recent command was a VIEW "NOSTATSHARE". But this is user-unfriendly. It would be better if $VIEW("STATSHARE") returns 0 if the most recent command was a VIEW:"NOSTATSHARE", returns 1 if the most recent command was a VIEW "STATSHARE", returns 2 if the most recent command was a VIEW "STATSHARE":reglist or VIEW "NOSTATSHARE":reglist

Issue 4)

$VIEW("STATSHARE",reglist) fails with a SIG-11 if a VIEW "NOSTATSHARE":reglist was done previously

YDB>view "NOSTATSHARE":"DEFAULT"
YDB>write $view("STATSHARE","DEFAULT")
