Major release 5.0.0

[simonmichal]

Dear XRootD community,

The first RC for 5.0.0 has been tagged hence I'm creating this issue so we have a place where we can discuss the upcoming MAJOR release.

Here is the link to tentative release notes:
https://github.com/xrootd/xrootd/blob/stable-5.0.x/docs/ReleaseNotes.txt

Please NOTE: this is a rough approximation of the actual release 5.0.0 meant for testing! That said, we STRONGLY ENCOURAGE you to test it!

Please NOTE: as this is a major release it is a unique opportunity to break ABI and hence if you have any request which needs breaking current (4.x.x) ABI please speak up!

Please NOTE: we especially encourage you to test the newly implemented TLS support, all the details on how to configure encryption on the server side can be found in:
https://xrootd.slac.stanford.edu/doc/dev50/xrd_config.htm#_Toc22335919

@simonmichal @abh3 OSG is very interested in an RC2, specifically something that contains
8229de9, so that we can build our xrootd-hdfs plugin

[simonmichal]

@brianhlin : I'm sorry for the delay (I was on sick leave and then on holidays), but now we are back on track with Andy and within ~2 weeks we should have the master branch in a state that is OK for RC2.

[pmusset]

@simonmichal any news on the RC2 ? I am interested in the xcache monitoring (05fef42 and de93530)

[simonmichal]

@pmusset : again sorry for the delay, we should have something next week

[osschar]

There isn't much of actual xcache monitoring in yet ... there is scaffolding from both sides (xcache - collection, core - reporting) but they are not connected yet. I have some progress towards that on a branch somewhere but I abandoned it a while back due to pressure from other projects.

What in particular are you interested in? I can take a look and see if I can push it through.

[pmusset]

Hello,
At least the summary monitoring which seems to be implemented in 05fef42 and de93530.
For the detailed monitoring, I would like to know what is it showing more than the summary one. There is some things described in the monitoring documentation linking to the pss documentation for the content description but I didn't find anything there. But there seems to be some kind of implementation here 8cb0406

[osschar]

OK, yess, Posix stats were put in by Andy. I have started working on collecting cache stats from XCache.

The detailed stream will provide information on per-directory basis, down to some depth for specified set of top levels.
