Output library / schema versions in JSON context block #1742

LebedevRI · 2024-01-23T23:43:00Z

Mainly, i want `get_git_version()` to return true version, not something sanitized.

LebedevRI · 2024-01-24T03:12:26Z

src/json_reporter.cc

+#if defined(BENCHMARK_VERSION)
+  const char library_version[] = BENCHMARK_VERSION;
+#else
+  const char library_version[] = "hello, bazel!";


I don't quite know what should be done for non-CMake.

in bazel we could add a define to the cc_library that maps to module_version() i think: https://bazel.build/rules/lib/toplevel/native#module_version

Yeah, i have no idea how to actually write that though. I've tried the obvious approach, but it may not work.

did you try native.module_version()? i think you were close. if it doesn't work we'll go with cmake and i'll hack on bazel.

Yes, i tried that first.

Let me look into that...

LebedevRI · 2024-01-24T12:47:52Z

Sorry, i have no clue how to do the bazel part.

dmah42 · 2024-01-24T12:53:55Z

Sorry, i have no clue how to do the bazel part.

blech ok. do cmake, i'll take bazel.

With

        "BENCHMARK_VERSION=\""+native.module_version()+"\"",

we get

ERROR: /home/runner/work/benchmark/benchmark/BUILD.bazel:71:32: name 'native' is not defined

LebedevRI · 2024-01-24T12:55:55Z

With

        "BENCHMARK_VERSION=\""+module_version()+"\"",

(which is the right syntax i guess?) we get

ERROR: Traceback (most recent call last):
	File "/home/runner/work/benchmark/benchmark/BUILD.bazel", line 71, column 31, in <toplevel>
		"BENCHMARK_VERSION=\""+module_version()+"\"",
Error: unsupported binary operation: string + NoneType

Does that mean there is no version string?
But MODULE.bazel has

module(
    name = "google_benchmark",
    version = "1.8.3",
)

https://bazel.build/rules/lib/toplevel/native#module_version

"If this package is from a repo defined in WORKSPACE instead of MODULE.bazel, this is empty. "

i guess we have both WORKSPACE and MODULE.bazel so it's returning no version?

LebedevRI · 2024-01-24T13:25:54Z

Right, i guess that makes sense, but it does not really tell me how to fix this. Sorry. :/

dmah42 · 2024-01-24T13:34:25Z

don't be. drop bazel, i'll deal with it. i think i know what we need to do.

src/json_reporter.cc

+  out << ",\n";
+
+  // NOTE: our json schema is not strictly tied to the library version!
+  out << indent << FormatKV("json_schema_version", int64_t(1));


Also, do we want the original (current) version to be 1 or 0 ?

current version is v1.8.3 so v1 to match the major.

just to confirm: with bzlmod enabled, this gets further. two things missing:

convert "none" to an empty string in BUILD.bazel for when bzlmod is disabled
figure out why it's failing with:

LebedevRI · 2024-01-29T13:23:46Z

figure out why it's failing with:

It needs to be -DBENCHMARK_VERSION="string" not -DBENCHMARK_VERSION=string.

@dmah42 thank you!

dmah42 · 2024-01-29T13:25:34Z

i just kept adding \ and it works.

        "BENCHMARK_VERSION=\\\"" + module_version() + "\\\"",

google#1742 changed the placeholder version from `0.0.0` to `v0.0.0`, but this line which was further dealing with it, was not updated. Fixes google#1792
