Hey @kayaercument 👋🏼
Thanks for this initial proposal!
In order to evaluate its feasibility, could you please also add tests for the new feature that show it in action? (Very similar to what we already have for the existing functionality)
Code that compiles and "does something" is much easier to judge than a simple interface addition.
We will definitely need some bike shedding on the naming scheme, but I think that is inevitable anyway and should be a simple refactor in any case.
This looks like a solid start!

(I think I can fix the coverage uploads from forks not working. let me check)

Here are a few minor comments while you are working on the tests.

include/qdmi/constants.h

include/qdmi/device.h

…c and their tests

Dear @echavarria-lrz and @burgholzer,

Please review the work. I will write the documentation after everything is finalised.

@kayaercument thanks for the proposal of integrating the query of environmental data into QDMI. I took the liberty and added few questions inline in the code. Those are open questions more on the fundamental side. Hence, I think it makes sense to find an asnwer to them first, before I or someone else goes through the code in detail.

Overall, all additions fit niceliy with the look and feel of QDMI. Just one minor point: Already for a review of the code, doxygen comments help a lot to understand what the functions are supposed to do. However, since you did not actively request a review and I just voluntarily took a look, I cannot really complain.

Hey @burgholzer and @ystade,

I and @mnfarooqi wanted to try use_oidc for the codecov report. However, it does not trigger. Could you please check?

burgholzer · 2025-09-17T13:05:08Z

Hey @burgholzer and @ystade,

I and @mnfarooqi wanted to try use_oidc for the codecov report. However, it does not trigger. Could you please check?

Yeah. Something seems to be broken with CI at the moment. I'll check.
Just fyi: we previously used OIDC for codecov already, but that didn't work either for forks and is unlikely to work because a fork does not have the right permissions to create a valid OIDC token for the main repository. Codecov actually tries to use the tokenless upload in these cases. However, it seems that something is messed up in some configuration which is why it still expects a token in these cases. Eventually, we might have to open a support ticket with them as it might very well be an issue that only they can fix.

burgholzer · 2025-09-17T13:26:27Z

CI is running again now. For some reason, the CI workflow was disabled 🤷🏼

It may be something to do with the settings in Codecov? For example:

By now I tripple checked all settings across the GitHub repository, the GitHub organization as well as codecov. They perfectly match a known-good setup we use over at the MQT where codecov reports from forks work just fine without any special handling.
At this point I am 99% sure this will require a support ticket with codecov.

Hi @kayaercument
@burgholzer asked me wether I can do another round of review as he couldn't find the time to do so. Hence, I started and got until the middle of the file include/qdmi/client.h (from the top in the "Files Changed" overview). Here in this file I realized that you do not seem to be done with the PR as a lot of my last comments lack a reaction. Consequently, I stopped in the middle and will wait for your ping when you wnt through the feedback. Thanks for the effort.

@burgholzer What is the latest state here regarding the CodeCov setup? Should these changes be reverted?

The current state is #154 (comment)

We should not need to explicitly set any secrets or tokens in workflows here. Any respective changes can be reverted here or should be moved to a separate PR that gets merged before this PR does.

It is reverted. Have any support tickets been created?

No. Would you mind creating one?

Same holds for this file as commented above.

It is reverted.

Suggested change

value == nullptr || (size != sizeof(decltype(query->start_time)))) {

value == nullptr) {

The check (size != sizeof(decltype(query->start_time))) must be placed somewhere differently because also other information than of the start_time's type can be returned, e.g., a sensor pointer. This check should be handled in the respective cases.

I am moving this to the 1.3.0 milestone for now as there still seems to be ongoing discussions that need to be resolved and the changes on main have been pretty stable for a while.
