I don't think your proposed solution works either. It seems you might
be missing the underlying problem. There are patterns that I see over
and over and I wish we can eliminate them, I will explain the general
patterns and then a suggestion for reasonable solution:
1- Wrong dependency direction: Framework should never know about core
apps. Core apps should never know about plugins. The arrow is always
from the outside to the inside. So when you create a solution, it
should always be generic and allow "plugging in" values from the
outside to the inside, not pulling or coding by hand
2- Global Shared Mutable State: The two keywords here are "shared" and
"mutable". The less we have of both, the better. So no, I don't have a
problem with having properties, I have a problem with global mutable
variables. They make the system much harder to reason about and debug.
So it is always better for a global variable to be immutable, and even
better, to not exist. However all systems require some level of global
variables but we should use them carefully and try to isolate their
impact. Essential things like database connections, tomcat sessions,
etc ... are reasonable, but going too far might be a problematic
architectural design, not a necessity.
So in the example we are discussing here, one idea for a solution
would be some kind of configuration (perhaps in ofbiz-component.xml)
where you declare whatever settings you want, and then the login
worker would simply loop over all components to decide. This is a
clean (outside-to-inside) solution instead of this hack job.
My recommendation is to revert all of this work, discuss a proper
solution in the ML, open a JIRA and provide a patch. I also recommend
_not_ committing any architectural changes without discussing them in
the community first.

Thanks for the review Taher,
Sorry I completely forgot this thread. When I wrote the
autoLogoutFromAllBackendSessions() method I let a TODO there
// remove all the autoLoginCookies but if in ecommerce/ecomseo and webpos
(it's done manually there, not sure for webpos TODO: check)
and I remember I thought about harcoding some applications was not good. And
especially, how to let know users, who need this feature, to keep the
autologin cookie in their custom plugins applications.
I know you don't like having too much properties. But to avoid hard wiring
these applications in the framework, Isuggest to have a new
keep-autologin-cookie security properties, with default OOTB plugins
# -- Names of the component where the autologin cookie should be kept one
This way, users who need to keep the autologin cookie just have to add the
concerned application/s to this list.
And autoLogoutFromAllBackendSessions() can then use this list to avoid
removing autologin cookies from these applications.
Would this work for you?
As I wrote in the TODO, I'm not sure why webpos have a the autoLogout
request-map in its controller. I'm not even sure the webpos really
implements it, like ecommerce does.
So we could remove webpos from the keep-autologin-cookie list.
I'll check that.
If it's really needed, as the autologin-cookie feature just remembers you
but does not sign you automatically (you need to know the password) I don't
think it's a security flaw.
Anyway, if it was the only problem with the webpos :/

I just checked this code and it looks really worrying to me. You have
hard wired the ecommerce component with logic into the heart of the
framework, I think we need to review the entire body of work and maybe

Almost 6 years ago OFBIZ-4959 "Logout do not remove autoLogin" was
and I closed as incomplete.
Recently while working on OFBIZ-10206 "Security issue in Token Based
Authentication" which followed my work in OFBIZ-9833 "Token Based
Authentication" I needed a way to get the userLoginId (or userLogin)
But, as explained in OFBIZ-10206, at this stage it was unavailable. So I
decided to go with autoLoginCookies. I then " remembered" OFBIZ-4959.
So I'd like to commit the patch I provided at OFBIZ-4959. But before
I want to discuss about autoLoginCookies and the feature to be sure we
all on the same field.
The auto login feature is used in ecommerce applications (ie OOTB
ecommerce and ecomseo) to welcome an user when s/he gets back. It does
really log the user in but eases the login process. From the code, the
feature exists in the webpos, I did not check.
AutoLoginCookies are also generated for all applications, but are not
for the auto login feature like in ecommerce applications. It can be
nevertheless useful as proves OFBIZ-10206 "Security issue in Token Based
Authentication". But for OFBIZ-10206 and security in general it's better
remove the autoLoginCookies of the other applications (ie no ecommerce
webpos) when the user logout. Of course if the user quits the session
login out the autoLoginCookies remains so it's best to start with a
state and remove the autoLoginCookies at start.
Without negative opinions I'll commit the OFBIZ-4959.patch in 1 week.
Forgot to say that the autoLoginCookies have a time to live of 1 year.
