Prebuilt binaries

[spmiller]

Hello,

Thanks for your efforts on this library! We find it fills an important part of our post-mortem toolkit, and we're particularly grateful for the work @paulrutter has done in working with the Node and V8 communities to get this implemented.

We have the pleasure of deploying on both Windows and Linux, and as this library needs a native component, we currently need to run an npm install on both OSes to get a suitable distribution.

Would you be interested in releasing pre-built binaries via node-pre-gyp? I would be happy to have a go at contributing a patch to support this via Travis / Appveyor.

Hi @spmiller,

Thanks for the appreciation!
I would certainly be interested in pre-built binaries; i'm not familiar with how this process would/should work, so i would need to investigate this further.
A patch/PR would really help here!

Let me know if you need help/review code 👍
TravisCI is already used, so that might help.

See https://travis-ci.org/github/blueconic/node-oom-heapdump

[spmiller]

Great, I'll start on this first thing Monday. It will be a learning exercise for me too!

Hi @paulrutter, I opened #11 for this. I've tested this on my fork, and it seems to work pretty well on both Linux and Windows (though I haven't a MacOS machine to test with).

This will only work if we create a Github release for each release, which I don't think is part of your current workflow (we need to store the binaries somewhere and Github seems as good a place as any). I can have a go at creating another Github action to automatically create a Github release whenever a release tag is created if you would like to keep your workflow the same?

Edit: I must have been blind, you are creating releases. In that case I don't think any further changes are required.

Hi @spmiller,

Thanks for your quick work! We indeed create Github releases for each release, with a version tag.
I'm in the middle of finishing a release sprint, after that i'll have more time to review the PR.

[spmiller]

Sounds good. Best of luck for your sprint!

[spmiller]

Thanks for merging! Perhaps a beta release first to try it out?

[paulrutter]

The action has run successful, but i'm not seeing the artifacts on https://github.com/blueconic/node-oom-heapdump/releases/tag/1.3.0. Could this be because it's a pre-release?

[spmiller]

Ugh, I can't see any documentation that says prereleases can't have assets uploaded. I'll try debugging on my fork. Sorry about this ☹️

[paulrutter]

Not a problem, even when 1.3.0 is used (npm install node-oom-heapdump) will fallback to building from source.
So nothing is broken ATM.

[paulrutter]

The weird thing is:

https://github.com/blueconic/node-oom-heapdump/runs/803163441?check_suite_focus=true

Vs your fork:

https://github.com/spmiller/node-oom-heapdump/runs/803237340?check_suite_focus=true

See the difference in output in the upload task.

[paulrutter]

I think i found it; the PR contained the "remove_path" in the package. After it was removed, the binaries appeared.
It looks like it's working now:

Too bad the gc-stats is not having all the right binaries in place, still falling back to building from source though.

[paulrutter]

Closing as fixed.
Thanks @spmiller!

[spmiller]

Thanks for debugging @paulrutter!

I think i found it; the PR contained the "remove_path" in the package. After it was removed, the binaries appeared.

Hmm, this doesn't make sense to me -- I had thought that remote_path was only used by node-pre-gyp to download the binaries. It shouldn't have had any effect on the upload action in the workflow?

I am slightly concerned that the upload step is unreliable when working with pre-releases. I'll keep playing in my fork and I'll see if I can get to the bottom of it.

At least submitting a PR for them shouldn't take me as much time this time round :)

[paulrutter]

Hmm, that's a bit concerning indeed. I tested a pre-release in your forked repo, which worked fine.
I read a bit more about Github Actions, and only found parameters to disable it for pre-releases. This would mean that it, by default, works the same as for regular releases.

A PR for gc-stats would be nice.
Let me know if you have any more info on the subject.
