[part of a series of meetings]



About one minute (uninterrupted) per person where they can answer two questions:

  • What I did last week (since the last meeting),
  • What I plan to do in the next week.

No questions until we get through everyone :)


To major things: completed removing disk storage in cell info service; back-ported into pool info service. Also, reworked snapshoting, also pulled it out of alarms.


Current planning for upgrade is 26 hours to run the updates. Looking like September.


Working with CDMI dCache -- a lot of reporting of issues with the CDMI server, filling some roll-out reports for EGI. Now working on the subnet support for cell communication. and find bugs.


Nothing special -- mostly preparing for teaching in HTW Berlin.


Nothing new, just arrived back from holiday. Jürgen is on parental leave, but handed over responsibility.


Focusing on releasing.


Docu (Developers' Guide) and macaroons in HTTP 3rd-party copy.

Special topics

Teaching in Berlin

Tigran mentioned that on 10--11 August, some 12 students from HTW Berlin will be participating in a course that will hopefully result in them sending pull requests.

The course's goal is to teach the students how to contribute to Open-Source projects, and dCache is the target.

We currently have some 7 simple tasks; see:

Some more simple tasks would be appreciated. Tasks should focus on a single file (maximum two files), so that they don't require strong knowledge of dCache.

Please be aware that the students will be sending pull requests some time after 10 August, so feedback (especially from our international colleagues) would be very much appreciated.


Dmitry is investigating how to buy licenses for Al and himself and wanted to know if they can get the same discounted price.

Third party HTTP third-party

There is a somewhat rambling discussion between different people on HTTP third-party copy requests. There are two aspects: initiating the request and acquiring an authorisation token with which the second-party server authorises the third-party copy. Brian B. proposes that the latter standardised on OAuth2.

Release news

Keeping with the weekly release cycle.

Current release cycle: Next release is tagged. working on release notes. Estimate that the next release will be out tomorrow.

Plan to release dCache v3.2 on 1st September.

This means branching 3.2 on Monday 28th August.

Everyone seemed happy enough with this deadline.

Trunk activity

Paul mentioned experimenting with dynamic X.509 certificate requests, using TLS renegotiation. The web-admin is being used as a demonstrator.
