- `XK6_K6_REPO` optionally sets the path to the main k6 repository. This is useful when building with k6 forks.


## `xk6-depsync`

In addition to `xk6`, this repository also includes the `xk6-depsync` command. `xk6-depsync` can be used to find common dependencies between a given go project, typically a k6 extension, and k6 core. For these common dependencies, `xk6-depsync` will look specifically for those that are required to be on a different version than what k6 uses, and generate a `go get` command to set it to the correct version. This is considered a good chance to minimize the chance of build-time errors and binary compatibility issues.

I do understand that this is related to xk6 (somewhat) and as this it seems like a good idea to keep it in the same repo, but:

Having gone through the code - none of the new code is dependent on xk6 or ... even specific about xk6. But it does add more dependency and makes the README harder to read by making it bigger.

The tool seems to be useful as well for any other projects trying to align their dependencies between different versions.

As such it seems to me it will be more useful to:

  1. Move this whole thing to a separate repo.
  2. the tool to take in another module name as argument.
  3. document here that you can use that repo to sync dependencies.

I agree that from an organizational point of view this tool should be its own module and/or repository.

However, considering that the tool itself is small and, for being a new tool, pretty much unused, I find hard to justify at this point of the tool's lifespan the operational burden of creating a new repository with is corresponding permissions, settings, ci/cd and release pipelines, etc.

I think we can always split the repo (or merge the command) if it starts making sense later on, while benefiting from the simpler operation and discoverability that sharing the repo provides.

Regarding:

But it does add more dependency

I agree and mentioned this here. I'll be okay with reverting 8ae8675 and switch back to the homemade string parser that does not have any external dependency at the cost of perhaps being less conformant with the go.mod spec, if you're okay with that tradeoff.

@roobre I miss this during my reviews, sorry. Why not create a dedicated go.mod file? This is an independent project in the end, being in the same repo doesn't force us to have the same project from Go's point of view.

If we can divide the Go Modules then I share the same feeling as you about having a different repository. A dedicated repo for only one file sounds a bit too much. IMHO.

@codebien No problem, I think creating a different go.mod should be okay. As we already have a go.mod in the root though, do you have any preference about where to put the new one? Would cmd/xk6-depsync/go.mod be okay? Should I also vendor the deps of the new module?

Would cmd/xk6-depsync/go.mod be okay?

Yep, it should be the idiomatic way these days for it. If you can do a quick research to confirm even better.

Should I also vendor the deps of the new module?

I don't think it's required. It's a very simple tool. But I don't have a strong opinion here.

Gave this a try. In order for go build to work, I had to add a go workspace. Otherwise the toolchain does not seem to understand it is a different module:

12:18:03 ~/Staging/xk6 $> go build ./cmd/xk6-depsync
main module (go.k6.io/xk6) does not contain package go.k6.io/xk6/cmd/xk6-depsync

I've tested using my fork that go install works as expected:

12:30:39 ~/Staging/xk6/cmd/xk6-depsync $> go install github.com/roobre/xk6/cmd/xk6-depsync@latest
go: downloading github.com/roobre/xk6/cmd/xk6-depsync v0.0.0-20231110113016-4811bd1cf67a

@codebien Eager to hear your thoughts on this :)

If you're not positive about the approach (go.work file and all) then perhaps we should go for the route that @mstoykov suggested and just create a new repo for this tool.

Moving the project to another repo also has the benefit of making the tool more general - taking the repo it is supposed to take in as an argument.

Also both tools won't get updated eveyr time the other is

At this point I have to say that :

  1. repos are free.
  2. CI for open source project is free.
  3. copying .github folders takes seconds

I would expect there is even a template repo that makes the above a single click

### `xk6-depsync` usage

`xk6-depsync` is included in the `grafana/xk6` container image, and can be run using docker by specifying its path as `--entrypoint`:

```bash
docker run --rm -it -u "$(id -u):$(id -g)" -v "${PWD}:/xk6" --entrypoint /usr/local/bin/xk6-depsync grafana/xk6
```

Running the command above on the root of a k6 extension will produce an output like the following:

```
2023/10/05 14:08:30 detected k6 core version v0.45.1
2023/10/05 14:08:30 Mismatched versions for gopkg.in/guregu/null.v3: v3.5.0 (this package) -> v3.3.0 (core)
2023/10/05 14:08:30 Mismatched versions for github.com/spf13/afero: v1.9.5 (this package) -> v1.1.2 (core)
2023/10/05 14:08:30 Mismatched versions for github.com/google/pprof: v0.0.0-20230426061923-93006964c1fc (this package) -> v0.0.0-20230207041349-798e818bf904 (core)
go get github.com/google/[email protected] github.com/spf13/[email protected] gopkg.in/guregu/[email protected]
```

The final line includes the `go get` command that, when run, will sync the versions of the detected shared dependencies to the version that k6 is using. `xk6-depsync` outputs this line to `stdout` so it can be piped to a shell, or redirected to a script for later use.

`xk6-depsync` can also be installed on the host using `go install`:

```console
$ go install go.k6.io/xk6/cmd/xk6-depsync@latest
```

### Trivia

Go versions earlier than 1.21 have been observed to behave unexpectedly in some cases, sometimes ignoring some of the versions specified in the `go get` command, or unexpectedly upgrading/downgrading other dependencies. It is recommended to run the `go get` commands suggested by `xk6-depsync` with Go >= 1.21.

Yes, we faced this in the xk6-disruptor project. We introduced this code as a script in this commit, which at the time yielded the following command:

go get github.com/spf13/[email protected] github.com/spf13/[email protected] golang.org/x/[email protected] google.golang.org/[email protected]

Running said command with Go 1.21 produced the following changes, which I would pretty much expect:

Consider using https://pkg.go.dev/golang.org/x/[email protected]/modfile#Parse instead of custom parsing logic, it would be a more robust solution....

I've given this a swing in the latest two commits. I wouldn't say I'm against it, but I'm not very convinced either. I don't see the code significantly less complex or significantly shorter either.

LMK what you think about this. If you prefer it this way, I'm happy letting it stay, otherwise I can drop the commits and get back to the original implementation. Your call :)

I didn't recommend it because of the complexity or length of the code. If there is a well-maintained, high-quality library for reading a file format, it is advisable to use it. This way you can avoid that your own parser does not exactly follow the file format specification.

BTW this is just a suggestion, it's up to the code maintainer to decide :)
