Account level syspref overrides in SIP will "leak" between SIP requests.
Basically an account level system preference override will may be set by a given request, but those overrides will never be cleared for the life of that SIP process thus "contaminating" that process until it reaches end of life".
This is because the code
# Clear overrides from previous message handling first
foreach my $key ( keys %ENV ) {
delete $ENV{$key} if index($key, 'OVERRIDE_SYSPREF_') > 0;
}
is checking if the env key contains the substring OVERRIDE_SYSPREF_ at an index greater than 0. The problem is that for all overrides the subtring *starts at 0* since it's always the first part of the string. If the substring is not part of the string index will return -1. TLDR we have an "off by one" error. We need to check that the return value is zero instead of any positive value.
1) Set your SIP server params so that only one SIP process should run,
<server-params
min_servers='1'
min_spare_servers='0'
max_spare_servers='0'
max_servers='0'
custom_tcp_keepalive='0'
custom_tcp_keepalive_time='7200'
custom_tcp_keepalive_intvl='75'
/>
2) Set noissuescharge to $5
3) Create two SIP accounts
4) Set an account level override for noissuescharge to $500
5) Create a patron that owes $10 in fines
6) Run a patron information request on the "normal" SIP account for the
patron, the patron flags should show the patron being not able to
check out items
7) Run a patron information request of the "overridden" SIp account for
the patron, the patron flags should show the patron being allowed to
check out items
8) Run a second patron information request on the "normal" SIP account
for the patron, the patron flags should show the patron being able to
check out even though they should not be able to check out
9) Apply this patch
10) Restart all the things!
11) Repeast steps 6-8
12) The flags should be correct!
