Hi,

Thanks for the PR. One small comment below, however the 32-bit build failures are the larger concern. I see you commented on IBM/nzgo#38

[powersj]

What is your plan to resolve the 32-bit build issues?

[mplpl]

I'm going to talk to IBM on Monday about that. It may take some time for this issue to become fixed.

[srebhan]

Just as a hint: As workaround you could guard the driver with build-tags excluding 32-bit archs (similar to sqlite)...

[mplpl]

Thanks for suggestion @srebhan
In the meanwhile I've opened a PR to nzgo to support 32-bit environments. Let's see how it goes (I'm in touch with the nzgo maintainer). If it does not, I'll go sqlite way.

@mplpl,

Looks like IBM/nzgo#60 was landed. Is an update to the version imported all that is required?

[mplpl]

@powersj My PR with support for 32-bit envs for nzgo was indeed merged, but a new version of this driver has not yet been released. I'm in touch with the maintainers and waiting for their decision about when to release it.

[powersj]

github.com/IBM/nzgo

They haven't seem to have tagged a release in 2 years. Our next feature release is in a few weeks and I would like to see this land in that, instead of waiting till March.

What we can do is import the repo at a specific commit, rather than a specific tag/release. Then if/when they do an actual release we can switch the go.mod entry to a commit hash.

[powersj]

@mplpl I have checked out your branch, rebased on our master, updated it to use nzgo with the master branch from today, and run go mod tidy.

[mplpl]

@powersj ok, thanks. It is Diwali holiday in India, and the person responsible for nzgo is away now. But she should be back in a few days and promised to update me with when they plan to tag a new version.

[Hipska]

Is it possible to add integration test like we have for others? Or would that not be easy to achieve?

[srebhan]

@Hipska I don't see any official container image, so having an integration test would be hard...

[srebhan]

Thanks for your contribution @mplpl! Feel free to bump the driver once a new release is out.
