pdurbin: thanks for less xhtml on API errors :)
14:45 pdurbin
sure, I'm writing a comment on https://github.com/IQSS/dataverse/issues/4396 now. how to test, etc
14:49 pdurbin
pameyer: ok, please take a look and add more if I'm forgetting anything important.
14:51 pameyer
will do
14:52 pameyer
and thanks for updating with develop
14:53 pdurbin
Sure, there were minor merge conflicts. I had added new methods in UtilIT in the same place. Not a big deal.

pdurbin: don't see anything to add to your notes there

Hi Philip
15:08 Thali_UM
In what is Dataverse programmed?
15:08 Thali_UM
Good morning
15:13 pameyer
morning Thali_UM: are you wondering about programming language, framework, OS , tools?
15:13 Thali_UM
All
15:14 Thali_UM
Language programming is JAVA?
15:14 pameyer
java , JSF / primefaces / a bunch of java ecosystem stuff I don't understand well enough , dev on OS X for deployment on linux
15:14 pameyer
I use vim/maven for dev tools, but most of the iqss team usees netbeans
15:14 Thali_UM
is a tools primefaces?
15:15 pameyer
primefaces is used to generate the web UI - it's a java library (or framework)
15:15 Thali_UM
Good morning pameyer
15:16 Thali_UM
Ok
15:16 pameyer
JSF and primefaces interact in ways that pdurbin would be better able to answer than me ;)
15:17 Thali_UM
Thank you for the answere Pameyer
15:17 Thali_UM
What tool do they use to document?
15:19 pameyer
the guides are written in restructured text, which is processed by sphinx
15:20 pameyer
there's some javadoc style comments in the source code, but my impression is that those aren't used very often
15:21 pdurbin
Thali_UM: good morning. Please see http://guides.dataverse.org/en/4.8.6/developers/intro.html#core-technologies
15:23 Thali_UM
Yes Philip
15:23 Thali_UM
Thank you Pameter and Philip
15:29 pameyer
glad to help
15:44 pdurbin
every lab should have a pameter ;)
15:45 pdurbin
Thali_UM: you can read more about our use of Sphinx at http://guides.dataverse.org/en/4.8.6/developers/documentation.html
15:46 Thali_UM
Oooohhhh
15:46 Thali_UM
Thank you Philip
15:48 pdurbin
pameyer: I can't decide if it's valuable to build and host an HTML version of the javadoc or not. I can kick off a build if you'd like.
15:50 pameyer
probably not too valuble - I can build it the html when/if I need to
15:50 pdurbin
yeah, now that we have this fix you put in: https://github.com/IQSS/dataverse/pull/3516
15:50 pameyer
assuming it hasn't broken again, of course ;)
15:51 * pdurbin
clicks "Build Now"
15:51 pameyer
* crosses fingers
15:51 pdurbin
It worked back in October! :)
15:52 pdurbin
still works: http://phoenix.dataverse.org/site/latest/site/apidocs/
15:53 pameyer
cool
15:53 pdurbin
we *could* use javadoc for https://github.com/IQSS/dataverse/issues/4549
15:53 pdurbin
but I think we're leaning toward a page in the dev guide using sphinx
15:57 pameyer
I think that just having it exist is good
15:58 pdurbin
yeah
15:58 pdurbin
or obviate the need for it :)
16:00 pameyer
or that

pdurbin: any ideas how hard the students in that class are load testing dataverse?
19:10 pameyer
aka - pile traffic on it until something fails, or target $x simultaneous users
19:13 pdurbin
pameyer: you should watch the video: https://bluejeans.com/s/7dg33/ ;)
19:14 pdurbin
In some notes I wrote "50 users ok, 69 users starts to fail"
19:14 pameyer
ah - gotcha
19:14 pameyer
I'll check it out later
19:15 pdurbin
He got some suggestions on how to improve his load testing. Not from me. I don't have much experience with JMeter.
19:15 pdurbin
It sounds like you record some actions and then play them back.
19:16 pameyer
me either - I looked at it minimally, and went with ab instead
19:16 pameyer
I might have even had a reason that made sense at the time...
19:18 pdurbin
ab was also mentioned at https://github.com/BU-NU-CLOUD-SP18/Dataverse-Scaling#solution-concept
19:18 pdurbin
I think a little load testing will be healthy for Dataverse.
19:18 pdurbin
shake out some bugs
19:20 pameyer
well, it's definately possible enough to load test Dataverse enough to effectively kill glassfish
19:21 pdurbin
with apache bench?
19:21 pameyer
if I'm remembering correctly
19:22 pameyer
wasn't very powerful VM config though, which was probably a factor
19:23 donsizemore joined #dataverse
19:32 pdurbin
We should probably offer more guidance on tuning and system requirements in the installation guide.
19:35 pameyer
it might be helpful, but the impression I've gotten is that system load isn't a big concern for most installations
19:37 pdurbin
Yeah, I'm more thinking about how much RAM we should recommend for a production installation. I'm not sure, to be honest.
20:30 donsizemore
@pdurbin i would've recommended 64GB (as vmware's current upper limit for fault-tolerant VMs) but Leonid's memory improvements really helped WRT harvesting
20:43 pdurbin
cool
