Participants: Andre, Daniel, Mariusz, Roger, Stephan Klauck, Peter
Meeting secretary: Peter

> 2. Status report by the participants

All in good health, some reporting from Peter about OGF35 in Delft

> 3. Public comments on DRMAAv2 C-binding

>   - pointer NULLing by the library ? What it means for the interface ?

- No decision at OGF35, voting needed
- Roger, Peter: "principle of least astonishment, no NULLing in the library"
- Andre, Daniel, Mariusz: "security problem, asynchronous free problem, OpenMPI example"
- 3:2 voting result for changing the API -> free* functions get pointer variable reference and assign NULL to it
- Voting also clarified that no other API changes are made

>   - Problems with OStype and CPUtype enumerations

- No decision at OGF35, voting needed
- 5:0 voting result for keeping MACOS identifier - OS version is already a separate concept in the API
- 5:0 voting result for changing TRUE64 to TRU64
- 5:0 voting result for adding 64bit variations of all instruction set architectures
- These changes demand an errata for the DRMAAv2 root specification

>   - Semantics of DRMAA2_DATA_SEG_SIZE

- No decision at OGF35, voting needed
- 5:0 voting result for the proposal by Rayson Ho: DATA_SEG_SIZE is renamed to DATA_SIZE
- Explanation must extended - this value refers to 'initialized data, uninitialized data and heap'
- These changes demand an errata for the DRMAAv2 root specification

>   - Additional free functions needed

- No decision at OGF35, voting needed
- 5:0 voting result for adding them

>   - Return type for wait functions

- OGF35 decision acknowledged by Roger
- IDL spec should have void return type for wait() functions
- Additionally, language bindings should be allowed to change the return type for chaining support
- These changes demand an errata for the DRMAAv2 root specification

>   - _j_ vs. _job_

- 4:1 voting result: Keep it as it is now

>   - Small issues   

-  jobCategories should be accessible outside the job session
     - Daniel: Need scheduler connection for fetching the information, and then again in the reservation session
     - Mariusz: Making a reservation without some job submission afterwards is very unlikely
     - 5:0 voting for keeping it as it is now
- Native drmaa2_string type, instead of char* pointers
     - OGF35 decision acknowledged by Roger
- UNSET for JobInfo: 5:0 voting for adding it
- Remove endIndex upper limit specification demand from the root spec
     - Demands an errata for the DRMAAv2 root specification

I will now start to prepare both the errata document and the final C binding for the editors. 

Best regards,
Peter.
