Two Datasets opened in parallel via OPeNDAP are loaded into same resource

[HelenClifton]

Expected behavior

If more than one dataset is loaded into memory via OPeNDAP at the same time, expect a separate resource to be created for each one.

Actual behavior

The tasks panel indicates that cate is only creating one resource and both datasets are being loaded into it.

Steps to reproduce the problem

1. Clear the workspace or create a new one

2. From ESA CCI Open Data Portal list, select esacci.AEROSOL.5-days.L3C.AEX.GOMOS.Envisat.aergom.2-19.r1 then click on “Download and/or open remote dataset”

3. In the “Download Data Source” window:
   • Deselect time, region, variable constraints.
   • Deselect “Download and make local data source”.
   • Select “open dataset from remote”
   • Click “Open Remote”

4. In Tasks panel, observe there is a new task displayed “Opening dataset res_1 from esacci.AEROSOL.5-days.L3C.AEX.GOMOS.Envisat.aergom.2-19.r1”

5. From ESA CCI Open Data Portal list, select esacci.OZONE.mon.L3.NP.multi-sensor.multi-platform.MERGED.fv0002.r1 then click on “Download and/or open remote dataset”

6. In the “Download Data Source” window:
   • Deselect time, region, variable constraints.
   • Deselect “Download and make local data source”.
   • Select “open dataset from remote”
   • Click “Open Remote”

7. In Tasks panel, observe there is a new task displayed “Opening dataset res_1 from esacci.OZONE.mon.L3.NP.multi-sensor.multi-platform.MERGED.fv0002.r1”

Same happens if trying to open more than one local dataset at the same time

[forman]

User should be able to provide a unique resource name

[forman]

@mzuehlke remember, 0.9.0-dev.5 in you've implemented a feature Prevent a 2nd (and 3rd) invocation of the variable statistics computation (but created no issue which I could ref here). This is another application of your fix. I'll try to generalize it for any operation invocation.

[forman]

For 1.0, it is sufficient to ensure unique resource names. Later we'll add a feature to let users provide their own resource names when opening datasets and applying operations. See #369.

[HelenClifton]

In cate-0.9.0-dev7 the functionality in the Download Data Source dialog to load into memory via OPeNDAP has been disabled.
In cate-0.9.0-dev7 it is still possible to open two local datasets in parallel and they will be assigned the same resource name. Will retest in 1.0.0.

Oops, OPeNDAP should be used automatically if any constraints are used. @kbernat, no?

Yes, yes, I have an idea...

[forman]

@HelenClifton I cannot reproduce your problem.

What exactly have you done to open two datasets that have same resource names?

[mzuehlke]

@forman can it be that the fix has only been merged after the release of 0.9.0.dev7 ?

[forman]

Yes. Shame on me.

[forman]

Furthermore, the OPeNDAP option has accidentally been removed while resolving #366! I will reintroduce it.

[forman]

It's not true. OPeNDAP should be used automatically when you uncheck option "Download and make local data source". I will clarify this with a tooltip in 1.0.

Sorry for this confusion, too many activities in parallel.

[forman]

@HelenClifton it'd be great if you could take a look again in 1.0.0.dev1 on Monday

[HelenClifton]

@forman Confirmed FIXED in 1.0.0.dev2
