Hey Jakub,
Just got back from break. That plan sounds fine to me.
Cheers,
Aaron

OK, making -rc1 release will be a step forward. Moreover, it will unblock all the actions I mentioned in my other mail.
What do you think about the following plan:
1. Make 3.7.0-rc1 release and tag the repository accordingly
2. Merge MultiplePorts branch into trunk
3. Move from code.google to github
4. Work on the new issues / wait for feedback regarding 3.7.0-rc1 / work on the "randomly doesn't work" issue
BTW. Aaron, can you create the ticket regarding "randomly doesn't work" issue with all the details regarding how to reproduce the issue?
Thank you in advance!
Regards,
Jakub.

other tasks which should be completed before it could happen?

When I installed older version as suggested there (7u67) I was finally able to successfully run applet. Again, running it multiple times resulted in working ok all the time so I wasn't able to reproduce bug.

odd that using windows and same security settings I didn't have such error (java version 8u25, on linux I have tried with the same version and 7u72 also). However it resulted in working all the time on windows and not working all the time on linux, wasn't
able to reproduce it the way you have mentioned. It would be helpfull to know what exactly versions of java they were using and what system/browser.

etc. Then have two ndt-server rpms for just the binaries, depending on the base package. The daemon would detect which version is installed and it could be manually configured if both were present. That would probably be the simplest route(aside from having
them conflict), but as you say, there is no web10g rpm so thats for the future.

RPM become a meta-package that grabs ndt-server-web100 and ndt-server-common. Another option would be to have “ndt-server” have web100srv, and have it depend on ndt-server-common. Upgrades would then work as expected.

Another option is to create a separate ndt-server-web10g RPM for web10g, since the web10g binaries do require the latest userlands as a dependency. What is your opinion on this?

the web100-dependent package, and vice versa. I’m not sure how the init script situation would work though.

something for me to click. I just have to blindly click in that box that’s below the blue page, and I’m given no guidance to do that. Beyond that, it’s rather jarring to have both appear in that page. If we could shrink the applet down so that it’s a very
small bar, and specifically note the “flash block” issue in the text somewhere (especially if they click “Start Test”, and it bombs out), that’d be vastly more intuitive.

Hello everyone,
I have been looking at updating the NDT RPM so that the flash
client there works out of the box(Issue162
<https://code.google.com/p/ndt/issues/detail?id=162>). I've
committed changes to the branch
Issue162(https://code.google.com/p/ndt/source/detail?r=1144), which
make the HTML5-frontend install with NDT and changed the index page
in the apache configuration to the new widget.html.
As far as running the Flash client out of the box goes, the NDT
server has to expose the crossdomain.xml file, which is required
for the Flash client to allow opening sockets to the server.
Unfortunately the socket policy does not go through HTTP, but a
simple proprietary protocol that uses the TCP port 843. I am
wondering for the best way to handle this in the NDT rpm. We can
possibly add a requirement for a package like
https://code.google.com/p/flashpolicyd/ and use that to serve the
file. We could also consider bundling some sort of a simple server
script(like this
https://github.com/xantus/mojo-websocket-examples/blob/master/script/flash-policy-server)
that would serve the policy file. Do you preferences on how to resolve this?
