net-mgmt/net-snmp needs JAIL : off to get Memory usage
Hello,
I've just solved a long-puzzling issue with net-mgmt/net-snmp which was not
reporting Memory Usage on my hosts.
Tests show it is related to the JAIL build-time configuration option.
JAIL=off: Options for running snmpd within a jail(8)
If off, the default, Memory Usage is available via snmpd.
If on, it is not.
One might ask: why have it on if not running in a jail?
Simplicity: I build my own packages. I could have one repo specifically for
hosts (i.e. non-jails), but until now, it's never been an issue.
However, I want to point that that JAIL=off does not seem to affect usage
within a jail.
It becomes clear what JAIL does when looking at the Makefile:
if ${PORT_OPTIONS:MJAIL}
NET_SNMP_WITHOUT_MIB_MODULE_LIST+= host
NET_SNMP_WITHOUT_MIB_MODULE_LIST+= ucd-snmp/memory
CONFIGURE_ARGS+=--without-kmem-usage
endif
Not it's clear. Don't report host-like objects when within a jail.
It is time for some flavors on this port? I know I'd like one for my use: one
without the above and with.
I'll see if I can mangle something up which works.

This works for me.

CI for ports
Hi! Can we please have at least BASIC continues integration for ports? Just check that it can be build and if tests exist then it run without errors. Or a bit advanced CI that also will build ports with all SSL/SAMBA/LLVM/etc versions. portlint and other atochekers and helpers can be integrateg to CI too. This all will make life easy for maiteiner and users will more happy. Also will be very nice to move from phabricator+Bugzilla to something more modern and useful, like gitea/gitlab...

I totally forgot about it. I have worked on one and it's functional. But I will activate it sometimes in the next month. You will be able to open a Github PR and the test will be done through Cirrus CI. Kind regards, Moin signature.asc Description: Message signed with OpenPGP

Is the ZPOOL option broken in poudriere?
Hi, I have a valid ZFS pool assigned to the ZPOOL variable. poudriere creates these directories in this pool: poudriere/ poudriere/jails These directories remain empty. poudriere works fine, but after the reboot all built packages disappear, and poudriere begins to rebuild them from scratch. I believe that ZPOOL either worked before, or it have never worked, because ZOOL was set like this for a long time without package disappearing. What is wrong? Thanks, Yuri
