Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

[h-vetinari]

Looks like either opentelemetry or arrow need an #include <winsock2.h> or #include <ws2tcpip.h> somewhere

[xhochy]

@h-vetinari You might get better error messages if you deactivate the unity builds. The error message triggers a gut feeling of "oh, maybe there is a macro defined twice".

Interestingly, this gets much further now (didn't know that knob). It now fails with missing symbols while trying to create arrow_acero:

release\arrow_acero.dll : fatal error LNK1120: 2 unresolved externals

The __cdecl arrow::internal::tracing::UnwrapSpan(class arrow::util::tracing::SpanDetails *) makes it look like this comes from arrow somehow (I'm guessing there are no shared windows builds with OTEL in upstream CI). Do we even need tracing in conda-forge? Isn't that usually for sanitizer instrumentation?

[xhochy]

The UnwrapScan function is probably missing an ARROW_EXPORT declaration: https://github.com/apache/arrow/blob/cdefbb8f4b4183b29fbcdb014af1f6fc0030475c/cpp/src/arrow/util/tracing_internal.h#LL125C1-L125C1

Although it is internal, it is used across library boundaries and thus it needs to be exported. Thus should be addressed upstream.

[h-vetinari]

Good analysis @xhochy. The build now succeeded, but we run into something else when trying to load the library:

import: 'pyarrow'

ImportError: DLL load failed while importing lib: A dynamic link library (DLL) initialization routine failed.

I haven't seen this before, but it seems there's some double-loading(?) of proto information into a protobuf-internal database?

If so, it sounds like arrow shouldn't be re-loading the otel proto definitions?

If so, it sounds like arrow shouldn't be re-loading the otel proto definitions?

To top things off, it looks like there's a third potential source for this (at least in conda-forge), in addition to opentelemetry & arrow: https://github.com/conda-forge/proto-opentelemetry-proto-feedstock

The opentelemetry lib includes this as a build dependency(?), which seems wrong somehow? Shouldn't it be a host-dependence?

Also, if there's a need to match the proto-opentelemetry-proto version here, I think this should become a run-export of libopentelemetry-cpp, rather than duplicating the version ("0.19") here and then trying to keep it in sync?

This happens if two libraries load the same protobuf definition in a different, conflicting version. We have the same problem with all the onnx-* packages. The workaround for this is build all (except at most one) with static protobuf so that each library gets its own protobuf (global) namespace.

[h-vetinari]

Thanks for the input!

This happens if two libraries load the same protobuf definition in a different, conflicting version.

Can we not ensure that they get the same protobuf definitions? There's even a specific feedstock for those.

[h-vetinari]

BTW: The recent commits also showed that the unity build was directly implicated in the windows failures. Switching it back on lead to failure again. Should I raise an issue for this upstream?

The Protobuf definitions are only needed to generate code, not at runtime. But the version needs to be matched, so if there's a better way...

Hmm, something seems wrong. Arrow itself shouldn't be loading the OpenTelemetry Protobuf generated code. Either we actually built a bundled copy of OpenTelemetry (doesn't seem so) or we still statically linked OpenTelemetry somehow? (Shouldn't be possible?) Or possibly multiple OpenTelemetry libraries included the Protobuf generated code?

Yes, please do.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...
