    v1 v1  
     3[part of a [wiki:developers-meetings series of meetings]] 
     5= Participants = 
     6Gerd, Al, Paul, Tigran, Karsten 
     8= Agenda = 
     10[see box on the right-hand side] 
     12= Postcards = 
     14Up to two minutes (uninterrupted) per person where they can answer two questions: 
     15 *  What I did last week (since the last meeting), 
     16 *  What I plan to do in the next week. 
     18No questions until we get through everyone :) 
     20Karsten: Parallel reading of files from dCache 
     22Al: Posted some patched, only few missing to commit the whole thing 
     23    Stress testing the alarms, looks satisfactory, but they are only  
     24    meant for 2.11 
     26Dmitry: Mostly opertional stuff, stuck transfers, globus online 
     28Gerd: Executive meeting, writing board report, ... 
     29      Worked on migration module 
     30      operational issues, debugging handshake timeouts 
     31      debugging SRM semi-deadlock 
     33Paul: GridKA School, dCache workshop + talk about federated identity 
     34      talked about future directions, preparing 
     35      fixing releases 
     37Tigran: JGlobus 2.1 + dCache, more complicated than expected 
     38        Problem with Voms-API, send fix to JGlobus, but no response, yet. 
     39        Undid changes in dCache, adapted to new BouncyCastle 
     40        Had problems on dcache-cloud, ncount got out of sync,... investigation ongoing 
     41        Got some patches from external contributors 
     43= Plans for patch-releases = 
     45Should we make a new patch release? 
     47We want to get releases out, but currently some unit tests are failing 
     48Jenkins slaves died, etc. 
     52Could this be because of increased concurrency and/or slowed down machines 
     53because of changed Virtual Machines state. 
     55There is a patch to remove race-condition from tests. 
     57But there are more. 
     591. AtomicCounter -> Gerd 
     602. BasicTest -> Tigran 
     613. following Tests will be distributed via eMail 
     63= Trunk activity = 
     65Progress with new features... 
     67== questions to tigran == 
     69Bulk deletetion through SRM: Atlas showed some slides with 30Hz deletion rate 
     70from multiple clients. Gerd managed to archive single client performance of 188Hz 
     72Atlas doing small file stages: Small Files scripts might help, but they are not  
     73ready to be distributed. 
     75== Globus Online == 
     76What's the status? 
     78Will be able to run tests on a production system next week. 
     79Currently there is no culprit that causes the failures. 
     82== jGlobus == 
     84We need a new jGlobus release, but unit tests are failing. 
     86Should we move away from jGlobus? We have some dependencies (principals), 
     87but other libraries provide similar functionality. Also srmClient depends. 
     89Gerd: We could have different versions for what is awailable in the dists. 
     91As soon as VOMS people upgrade, we get the new BouncyCastle and also Canl. 
     94= Issues from [FIXME: Add link to yesterday's Tier-1 meeting] = 
     96Xavier, Marc, Gerd:  
     97Xavier discovered overloading pools. Advised to upgrade pool manager.  
     98  - Billing file logs: Pool manager sending information to billing 
     100Gerd: using 2.10.3 except for some problems 
     102= Outstanding RT Tickets = 
     104[This is an [wiki:TicketActions auto-generated] item.  Don't add items here directly] 
     1068442: This should rather be logged at INFO or DEBUG and change the output default pattern 
     107      The "suspended" case, there may be an error code missing 
     1098427: Could this be caused by different root paths? -> get more config 
     110      => We should improve the error message as well. 
     111      => avoid logging it twice. 
     113= Review of RB requests = 
     1157183 -> Paul to have a look 
     1167289 -> Karsten to have a look 
     118Also please have a look at Al's Alarm patches 
     120= DTNM = 
     122Proposed: same time, next week.
