RE: Seems that I found bugs related to stash_cashe in 5.7...

Bart,
I was installing the patch listed in the email below and wanted to verify the following:
It possibly looks like the following line should be ifndef instead of ifdef?

+++ b/agent/mibgroup/mibII/tcp.c
-#ifdef NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS
+#ifdef NETSNMP_FEATURE_REMOVE_TCP_COUNT_CONNECTIONS

Possibly should be:
+#ifndef NETSNMP_FEATURE_REMOVE_TCP_COUNT_CONNECTIONS

Please confirm,
Thanks

The first and immediate fix is to:
#define NETSNMP_FEATURE_HAS_STASH_CACHE
In a place that all_helpers.c will see it

That's wrong because that would break the configure option --enable-minimal. See also https://sourceforge.net/tracker/?group_id=12694&atid=312694 for a proper patch.

Add to your snmpd.conf:
injectHandler stash_cache nsModuleTable table_iterator

try to execute snmpd with follow cmd line:
snmpd  -DinjectHandler,helper:stash_cache,initialize_table_nsModuleTable -c snmpd.conf

What I see in the logs with both 5.7 and 5.6 after having applied the aforementioned patch is:

injectHandler: injecting handler cache_handler into nsModuleTable

So iterator injection seems to work fine.
But I'm not sure that your claim is correct that the stash_cache is working fine in 5.6 - a MIB walk times out at the end of the host resources MIB with 5.6:
$ agent/snmpd -Mmibs -c ../snmpd.conf -f -Lo -DinjectHandler,helper:stash_cache,initialize_table_nsModuleTable :1161 &
[ ... ]
$ apps/snmpwalk -Mmibs -v2c -cpublic :1161 .1
[ ... ]
HOST-RESOURCES-MIB::hrSWRunPerfMem.32504 = INTEGER: 663508 KBytes
Timeout: No Response from :1161

The above test works fine with 5.4 and 5.5 however.

Bart.
