New Action Items
- [AI] Chris investigate decorating and filtering issues around API caching
- [AI] Chris share API caching code with Bert for possible use in PSPNG
- [AI] Shilen look at GRP 1978 https://bugs.internet2.edu/jira/browse/GRP-1978
- [AI] Chad update coding standards wiki re branches https://spaces.at.internet2.edu/x/jY1HBQ
Big performance improvement thru caching
After security is run and other procedures
Will start caching down where network traffic goes
Will span all grouper users
Grouper subject source will be excluded by default
More sophisticated than H Cache
Used to only return one identifier max
So new method , subject identifiers all
Gives warning method if looking up something not configured
Can read from disk when you start Grouper
Question about decorating and filtering, Chris will double check
Use case to wipe out name if private.
Immutable subject object?
People don’t often edit subjects
Cloning would be least risky, Chris may take that approach
Can look up in background so run time process does not need to
Will write out stats to log daily or more often
Minor tweak so don’t need to go to subject source as often
Bert: PSPNG needs subjects to target system info it caches
Static info on subjects in target systems , now stored in Grouper cache objects
Could be too numerous to make attributes, with each target system potentially having info that needs to be stored
Can that be stored with this cache? Or duplicate with PSP NG?
Chris: this just caches subject and attributes
So PSP NG should keep doing its own caching
Anything Bert can re-use?
Chris will think about it.. And share code with Bert
Instrumentation (can we get it working?). Version in TIER env var
JIRA on this
There is a TIER production instrumentation server
They have a different protocol
Label as -test
Tested internally and not sure how stable
3 criteria to say it’s not in test status
If a few people have used
If a certain amount of time has passed
If see thru instrumentation that people are running and haven’t complained
Want version of the TIER container
Environment variable in the container that Grouper could read
Makes sense to create another Daemon thread to do this?
Shilen will look at GRP 1978
Versioning strategy doc
Please review this
To clarify what was discussed at the Tech Ex 2018 BOF
Issue of publishing branches to remote repository
This can clutter up list of branches and it’s already long and git does not show whole list.
So will need to prune when things get merged back into master.
Use naming convention so they show up at end of list?
AI Chad will update this page re branches
A lot of patches change config files
Try to make config file changes low impact
Chad jar issue
Chad will take a look
Chris will take a look, could change the order, or delete what is redundant
Upgrading API in UI build
Copying 2.4 UI as is
- TIER package helps with some of these issues
Current work tasks, and next tasks
Vivek – TIER types, rabbitmq routing keys, role inheritance, provisioning in ui
Provisioning in UI https://spaces.at.internet2.edu/display/Grouper/Grouper+provisioning+in+UI
Will this load down the Grouper loader?
First is getting PSPNG to implement the interface that will show this on the screen.
Use the UI to decide about provisioning.
Need to migrate and transition. If you specify in config file to use the original,that’s the default.
If you switch, it converts everything over.
Or wait until release of Grouper 2.5?
Now there is selection filter in PSP NG, to determine if selected for provisioning
Use an “or” in filter until Grouper 2.5?
Chris: need people to flip a switch
Could be GSH
Can do normal patches and do an enabling process involving GSH or loader properties change
What about people doing a scripted older method? They should not do this switch…
This is just for PSPNG
This will make Bert’s job easier
Every object going to a provisioner will be tagged
Inherit attribute from a folder
Chris – working on Database configs, subject caching
Bert – PSPNG patches
GRP-1911: attribute provisioning prefix
GRP-1494: backoff and queuing
Question on message formats
There is much boilerplate
3 types of messages that PSP NG handles
Full sync group
Full sync subject in group
Sync a subject to be right in all the groups
Lightweight JSON or bean definition?
Do we want to do strict defining a bean to serialize and de serialize JSON
Or use anonymous maps?
Bert will document in an email…
Chris uses JSON object,
web service uses beans w automatic conversion
There is not a coding standard for this currently
GRP-1533: DN escaping: needs to know which strings need to be escaped, from a config, not reading an LDAP schema, go live with config value that works for AD and openldap,
comma part of DN or not?
90% solution using the config value saying this attribute needs to be escaped
Rather than reading from LDAP schemas
And allow changes when needed
Bert: Two of the patches should be out this weekend, other one by next Wed.
membership UI improvements
Added Grouper sysadmin w start and end date
Can trace that info
Can see enabled and disabled dates
Other options for filtering
Point in time not started yet
Will be able to put in a from and to date
Row for every membership record?
Could be cleaner to do users versus memberships
Bert: like focus on members
Trace shows all relationships w group
There is no point in time trace
will privileging live in UI?
Could go to membership finder.
Chad - visualization
Wiki page is complete as far as APIs
Builds a graph
Visualization classes looks at Grouper.properties, has inheritance hierarchy
It’s in a local branch , but Chad will put out to the remote
1st patch in about 3 weeks will have graphing API, sample properties for stylings, will simulate what Michael G did.
Hope to do UI , but starting w command line
Will SVG have features the UI won’t have?
Can write a script for whatever you want the output to be
Can query it to find out what kind of object
All logic can go into scripts
Or can build in standards
Will build the UI around well established API logic
Chris : more interested in cross platform, so focus time there
Text based will show in the UI
Next Grouper Call: Wed. Jan 23, 2019
