[09:52:07 CST(-0600)] <EricDalquist> looks like we might be getting some more QA resources for uP4 
[10:16:01 CST(-0600)] <EricDalquist> athena: you there?
[10:26:17 CST(-0600)] <Arvids> EricDalquist, glad you´re here
[10:26:24 CST(-0600)] <EricDalquist> yeah, was out sick yesterday
[10:27:15 CST(-0600)] <Arvids> I rewrote that tab ID lookup - XPath did lookups in 1-50ms, but manual traversing does the same thing in 0.05-0.15ms
[10:27:37 CST(-0600)] <EricDalquist> wow nice
[10:27:44 CST(-0600)] <EricDalquist> +1 for that change
[10:27:45 CST(-0600)] <Arvids> that speeds up response times by 30-40%
[10:28:08 CST(-0600)] * EricDalquist cannot wait to have time to just re-write the layout manager/store layer
[10:28:25 CST(-0600)] <EricDalquist> xslt is find for the rendering pipeline but it would be nice to not treat the actual layouts as DOMs
[10:28:26 CST(-0600)] <Arvids> it turns out that those lookups are made at each URL building request
[10:28:38 CST(-0600)] <EricDalquist> ah ... yeah they would be
[10:28:56 CST(-0600)] <EricDalquist> one thing I've always wanted to write but never had time would be a @RequestCache annotation
[10:29:00 CST(-0600)] <EricDalquist> and supporting code
[10:29:07 CST(-0600)] <Arvids> btw, i can give you a patch, but I won´t have time to commit it today myself
[10:29:14 CST(-0600)] <EricDalquist> that will work
[10:29:28 CST(-0600)] <EricDalquist> being able to annotated a method with @RequestCache and have the method result be cached in a request attribute
[10:30:44 CST(-0600)] <Arvids> https://gist.github.com/1607350
[10:31:42 CST(-0600)] <EricDalquist> so have you tested this on mobile?
[10:31:54 CST(-0600)] <Arvids> no
[10:32:10 CST(-0600)] <EricDalquist> the way things work the UrlNodeSyntaxHelper impl is associated with the structure transform
[10:32:18 CST(-0600)] <EricDalquist> so the logic to find the correct tab needs to be in there
[10:32:57 CST(-0600)] <EricDalquist> since a different structure, like mobile, doesn't have the same url structure as the tab/column structure
[10:34:16 CST(-0600)] <Arvids> ok, i hope i will have some time to inspect that next week
[10:34:31 CST(-0600)] <EricDalquist> well at least we know that it is a problem
[10:35:03 CST(-0600)] <Arvids> yeah, i also did some search on google.. and it gave very little results, but there were some hints
[10:35:12 CST(-0600)] <Arvids> one is: https://issues.apache.org/jira/browse/XALANJ-2540
[10:36:13 CST(-0600)] <Arvids> http://stackoverflow.com/questions/6340802/java-xpath-apache-jaxp-implementation-performance
[10:36:43 CST(-0600)] <Arvids> the one question from stackoverflow is supporting my conclusions - XPath is slow
[10:36:47 CST(-0600)] <EricDalquist> uhg
[10:36:49 CST(-0600)] <EricDalquist> that sucks
[10:37:01 CST(-0600)] <Arvids> yes, it does
[10:37:39 CST(-0600)] <Arvids> it is very nice to write some delarative code that looks up the stuff you want... but the performance penalty is too great
[10:37:50 CST(-0600)] <Arvids> declarative*
[10:37:54 CST(-0600)] <EricDalquist> yeah
[10:38:06 CST(-0600)] <EricDalquist> the sad thing is it shouldn't be that expensive
[10:38:17 CST(-0600)] <EricDalquist> and there are alternative xpath impls for java that I'm betting are fast
[10:38:30 CST(-0600)] <EricDalquist> but last I looked jdom and dom4j are both essentially dead
[10:39:43 CST(-0600)] <Arvids> I also saw some comments saying that VTD-XML is fast, but last release was almost year ago
[10:39:50 CST(-0600)] <EricDalquist> yeah
[10:39:58 CST(-0600)] <EricDalquist> jdom looks like it just had a patch release
[10:40:19 CST(-0600)] <EricDalquist> and dom4j had its last release in april of 2010
[10:41:47 CST(-0600)] <EricDalquist> though due to cernunnous we have jdom 1.0 and dom4j 1.6.1 on the classpath
[10:42:20 CST(-0600)] * EricDalquist gets frustraited by having so many libraries that duplicate functionality in the classpath :/
[10:43:50 CST(-0600)] <Arvids> btw, do you have some ideas regarding new layout architecture?
[10:44:02 CST(-0600)] <EricDalquist> I do have some
[10:44:11 CST(-0600)] <Arvids> will it be XML-based or POJOs?
[10:44:20 CST(-0600)] <EricDalquist> pojo at the data level
[10:44:31 CST(-0600)] <EricDalquist> so create a pojo tree that stores the layout stucture
[10:44:46 CST(-0600)] <EricDalquist> layout nodes can then have true references to IPortletDefinition objects
[10:44:57 CST(-0600)] <EricDalquist> and the IPortletEntity object can be merged into the layout node
[10:45:51 CST(-0600)] <EricDalquist> the pojo structure will need to capture the different types of nodes that can exist in a DLM style
[10:46:17 CST(-0600)] <EricDalquist> folder, portlet, dlm:move, dlm:add, dlm:delete, dlm:edit
[10:46:28 CST(-0600)] <Arvids> btw, I also did some tinkering on JpaPortletEntityDao
[10:46:31 CST(-0600)] <Arvids> here´s diff: https://gist.github.com/1607439
[10:46:58 CST(-0600)] <EricDalquist> part of the goal with moving this to a pojo structure is to be able to more reasonably generate a "state key" for each layout
[10:47:00 CST(-0600)] <Arvids> it turns out that manual loop through user entities fastens the whole thing
[10:47:42 CST(-0600)] <EricDalquist> then the DLM merging logic would need to be re-written from XML based to work with the pojo setup
[10:48:22 CST(-0600)] <EricDalquist> though with the way the rendering pipeline works the DLM merging logic would hopefully become just a rendering pipeline component
[10:48:28 CST(-0600)] <Arvids> ok, i have to go now (it´s friday evening after all)
[10:48:47 CST(-0600)] <EricDalquist> heh
[10:49:05 CST(-0600)] <EricDalquist> I'll see if I can document some of these layout manager re-write ideas
[10:49:13 CST(-0600)] <Arvids> that would be nice
[10:49:30 CST(-0600)] <Arvids> we should somehow address XPath problem, too
[10:49:40 CST(-0600)] <Arvids> manual traversing is painful
[10:49:58 CST(-0600)] <EricDalquist> yeah
[10:50:53 CST(-0600)] <Arvids> ok, bye now... hope you´ll get some pull requests on monday
[10:57:24 CST(-0600)] <athena> hey EricDalquist, what's up?
[10:57:42 CST(-0600)] <EricDalquist> just a few questions about the spring-sec stuff you're working on
[10:57:49 CST(-0600)] <EricDalquist> in relation to some events stuff I'm working on
[10:59:03 CST(-0600)] <EricDalquist> with spring-sec will users "authenticated" on every new session?
[10:59:07 CST(-0600)] <EricDalquist> including guest users?
[11:00:40 CST(-0600)] <athena> yeah but i think they wind up w/ an unauthenticated session
[11:00:44 CST(-0600)] <athena> using the anonymous auth stuff
[11:01:01 CST(-0600)] <EricDalquist> right
[11:01:14 CST(-0600)] <EricDalquist> so in the aggregation we need to track "event sessions"
[11:01:24 CST(-0600)] <EricDalquist> which contains the groups that the user the event was fired for is in
[11:01:45 CST(-0600)] <EricDalquist> what I would like is that a LoginEvent (might need to rename that) is fired for ALL users unauthed and authed
[11:02:02 CST(-0600)] <EricDalquist> just wondering if that was going to fit with your spring-sec work
[11:03:36 CST(-0600)] <athena> yeah i think that sounds doable
[11:03:45 CST(-0600)] <athena> i think there might already be some eventing in there we can hook inot
[11:04:21 CST(-0600)] <EricDalquist> great
[11:19:02 CST(-0600)] <athena> here we go: http://static.springsource.org/spring-security/site/docs/3.0.x/apidocs/index.html
[11:19:13 CST(-0600)] <athena> so actually i think i got everything fixed up enough yesterday to create a branch
[11:19:31 CST(-0600)] <EricDalquist> oh neat
[11:19:51 CST(-0600)] <athena> yeah
[11:19:59 CST(-0600)] <athena> have CAS login working
[11:20:09 CST(-0600)] <athena> and local login, though that's only with spring's default login page
[11:20:14 CST(-0600)] <athena> so outstanding stuff includes
[11:20:23 CST(-0600)] <athena> 1. login portlet that can work w/ the local login stuff
[11:20:31 CST(-0600)] <athena> 2. recreating all the impersonation stuff
[11:20:37 CST(-0600)] <athena> 3. CAS clearpass
[11:20:48 CST(-0600)] <athena> 4. Proxy CAS and making sure CAS tickets get into the userinfomap
[11:20:53 CST(-0600)] <athena> 5. getting passwords into the userinfo map
[11:20:58 CST(-0600)] <athena> and probably some other stuff
[11:21:07 CST(-0600)] <athena> so certainly not done, but maybe working enough to be interesting
[11:22:30 CST(-0600)] <EricDalquist> very interesting
[11:22:37 CST(-0600)] <athena> yeah
[11:22:40 CST(-0600)] <athena> i mean, it does work
[11:22:43 CST(-0600)] <athena> reasonably clean
[11:22:52 CST(-0600)] <athena> not thrilled about the state of their documentation or their autowiring business
[11:23:01 CST(-0600)] <EricDalquist> :/
[11:23:05 CST(-0600)] <athena> and not thrilled that it seems the portal just silently fails to start up when things are misconfigured
[11:23:09 CST(-0600)] <athena> don't know what's going on there
[11:24:37 CST(-0600)] <EricDalquist> :/
[11:24:39 CST(-0600)] <EricDalquist> that is no fun
[11:24:41 CST(-0600)] <athena> yeah
[11:25:13 CST(-0600)] <athena> seems like what crashes it is usually a mismatch between the expected bean properties and what's misconfigured in the spring file
[11:25:22 CST(-0600)] <athena> but don't understand why that doesn't seem to produce more stack traces
[11:25:37 CST(-0600)] <EricDalquist> yeah
[12:00:10 CST(-0600)] <EricDalquist> so just discovered this: http://eggsylife.co.uk/2010/02/03/spring-annotation-based-aop-and-intercepting-the-ball/
[12:00:18 CST(-0600)] <EricDalquist> how to write a custom annotation
[12:00:25 CST(-0600)] <EricDalquist> and associate an interceptor with it
[12:00:30 CST(-0600)] <EricDalquist> in ~ 30 minutes
[12:57:17 CST(-0600)] <athena> ooo
[12:57:25 CST(-0600)] <athena> that sounds aawesome
[12:57:38 CST(-0600)] <EricDalquist> just finished uit
[12:57:51 CST(-0600)] <EricDalquist> there will be a @RequestCache annotation
[12:58:03 CST(-0600)] <EricDalquist> methods annotated with it will cache their result in the attributes of the current request
[12:58:16 CST(-0600)] <EricDalquist> and automatically re-use the cached result for the duration of the request
[12:58:35 CST(-0600)] <EricDalquist> Arvids had noticed that thigns like looking up the default tab nodeid ran for every url generation'
[12:58:44 CST(-0600)] <EricDalquist> even though that is the same for every urkl in the reuqest
[14:03:58 CST(-0600)] <EricDalquist> https://github.com/Jasig/uPortal/commit/68051fb9c9aa683f32d00a0fc8ac97fd900e8faa
[14:04:01 CST(-0600)] <EricDalquist> there we go
[14:05:33 CST(-0600)] <athena> oh nice
[14:05:41 CST(-0600)] <athena> is that the performance stuff he wanted to talk about before?
[14:05:54 CST(-0600)] <EricDalquist> well it is part of addressing it
[14:06:03 CST(-0600)] <EricDalquist> apparently xpath in the core JDK apis is terribly slow
[14:06:22 CST(-0600)] <athena> ah, interesting
[14:06:29 CST(-0600)] <EricDalquist> like 5-60ms to get the tabid for a random layout node id
[14:06:38 CST(-0600)] <EricDalquist> and that would run every time a url was generated
[14:06:41 CST(-0600)] <athena> oh wow
[14:06:47 CST(-0600)] <athena> yeah i guess that'd make a difference
[14:07:19 CST(-0600)] <EricDalquist> he got a huge boost by just navigating the DOM manually
[14:07:25 CST(-0600)] <EricDalquist> his patch just did it in the wrong place
[14:07:43 CST(-0600)] <EricDalquist> the other patch that helped a lot was not looking up portlet entities directly by user+layout+node
[14:07:51 CST(-0600)] <EricDalquist> instead getting all entities for user+layout
[14:07:59 CST(-0600)] <EricDalquist> then iterate on them comparing the nodes
[14:08:04 CST(-0600)] <athena> sounds like really good stuff
[14:08:06 CST(-0600)] <EricDalquist> yeah
[14:08:16 CST(-0600)] <athena> really glad he's involved
[14:08:21 CST(-0600)] <EricDalquist> a lot of this stuff is a result of only being part way to hibernate/jpa
[14:08:30 CST(-0600)] <athena> ah, yeah
[14:08:39 CST(-0600)] <EricDalquist> if everything was actually part of our JPA model we could essentially load it all when the user logs in
[14:08:49 CST(-0600)] <EricDalquist> or load it in reasonable chunks
[14:09:01 CST(-0600)] <EricDalquist> getting users + layouts moved over will be huge for reducing DB io
[14:09:05 CST(-0600)] <athena> yeah
[14:09:09 CST(-0600)] <EricDalquist> since then we can really have one object graph per user
[14:09:11 CST(-0600)] <athena> would love to get that work done
[14:09:18 CST(-0600)] <athena> maybe after stats?
[14:09:20 CST(-0600)] <EricDalquist> and load the whole graph at login with a minimal number of calls
[14:09:21 CST(-0600)] <EricDalquist> yeah
[14:09:24 CST(-0600)] <EricDalquist> after stats
[14:09:28 CST(-0600)] <athena> how's the stats stuff going, by the way?
[14:09:32 CST(-0600)] <EricDalquist> and after I get 4.0 deployed here
[14:09:33 CST(-0600)] <EricDalquist> good
[14:09:40 CST(-0600)] <EricDalquist> the branch is making good progress
[14:09:48 CST(-0600)] <EricDalquist> I just keep realizing more gotchas 
[14:09:50 CST(-0600)] <athena> lol
[14:09:55 CST(-0600)] <EricDalquist> I had forgotten how complex that aggregator was
[14:10:01 CST(-0600)] <EricDalquist> its translating over just fine
[14:10:11 CST(-0600)] <EricDalquist> it is just A LOT of daos/entities
[14:10:23 CST(-0600)] <athena> yeahi 'm sure
