Description Magnus Glantz 2019-01-23 23:07:56 UTC 
Created attachment 1522906 [details]
redhat.repo file created from registering system

Description of problem:
The end-user problem is that when you check for Software Updates in Cockpit, this takes ~9 minutes. The reason for this is because subscription-manager does not properly configure disabled repositories, at least for this use-case.

When you register a system with 'subscription-manger register --auto-attach' on RHEL8 HTB Snapshot 2 (latest at time of writing), then registries which are NOT enabled are missing 'enable_metadata = 0'. 

This is not a problem when running 'yum/dnf' but when PackageKit processes metadata, it will process any repository which does not have 'enable_metadata = 0' defined. So, if you have a lot of disabled repositories, then when PackageKit looks for updated metadata for repositories to provide Cockpit with information, it takes minutes, instead of seconds. Information about PackageKit behavior was given by Richard Hughes, here: https://bugzilla.redhat.com/show_bug.cgi?id=1667111

On my test system, with some 50 disabled repositories, this effectively destroys Cockpits ability to check for updated software, as no end user will wait for 9 minutes while a white webpage loads (PackageKit walks through 50 disabled repositories).

Here's an example from /etc/yum.repos.d/redhat.repo regarding an disabled repository.

[rhel-atomic-7-cdk-3.0-source-rpms]
name = Red Hat Container Development Kit 3.0 /(Source RPMs)
baseurl = https://cdn.redhat.com/content/dist/rhel/atomic/7/7Server/$basearch/cdk/3.0/source/SRPMS
enabled = 0
gpgcheck = 1
gpgkey = http://
sslverify = 1
sslcacert = /etc/rhsm/ca/redhat-uep.pem
sslclientkey = /etc/pki/entitlement/1616464139763360633-key.pem
sslclientcert = /etc/pki/entitlement/1616464139763360633.pem
metadata_expire = 86400
ui_repoid_vars = basearch

Version-Release number of selected component (if applicable):
RHEL8 HTB Snapshot 2 (latest at the time of writing)
subscription-manager-1.23.8-4.el8.x86_64

How reproducible:
Always

Steps to Reproduce:
1) Register Red Hat 8 HTB system with 'subscription-manager register --auto-attach'
2) Review /etc/yum.repos.d/redhat.repo
3) Run: 'pkcon -vp refresh force' and observe how disabled repos are processed, as expected from PackageKit's point of view.
4) Remove package definitions completely or add enable_metadata = 0 and observe how all is well.

Actual results:
subscription-manager does not define 'enable_metadata = 0' for disabled repositories.

Expected results:
subscription-manager defines 'enable_metadata = 0' for disabled repositories.

Additional info:
From RHEL 8 HTB program. BZ will be added to HTB tracker.

Comment 7 Craig Donnelly 2019-02-07 19:07:14 UTC 
Magnus,

We have implemented the fix on the subscription-manager side - 'enable_metadata = 0' is applied to all of the inactive repositories from the sub-man perspective.
With that said, it is still really slow in my opinion - and I still wouldn't wait the 48 seconds it took to loop through all of them anyway (Not on a web-page with no feedback, anyway).

That being the case, would you mind verifying this bug from your side that it meets your expectations?
From my standpoint this is now VERIFIED as far as subscription-manager is concerned.

Comment 8 Magnus Glantz 2019-02-07 20:15:45 UTC 
That seems weird, PackageKit seems to still be processing the repositories in your test. 
AFAIK, it should just print out: 

"Status: 	Downloading repository information" 

..twice - as only two repositories are enabled and without enable_metadata = 0. Let me test this.

NEEDINFO on sudo
As alluded to in comment 7 and comment 8, pkcon appears to be downloading cache for all 18 of the repos regardless of the enabled/enable_metadata setting.  If this is wrong, then please open a bug against PackageKit and link it back to this bug for reference.
Comment 10 Magnus Glantz 2019-04-03 07:57:50 UTC 
I'll open a BZ to PackageKit and link it here.
Comment 11 Richard Hughes 2019-04-04 08:08:40 UTC 
The logic is sound, but there's a typo in this report and also the subman fix -- the option is called "enabled_metadata" NOT "enable_metadata".
