That is pretty cool!

Do you know why dotnet process seems to use 100% cpu while pulumi cli is working?

Not sure, guess I left a busy loop in somewhere. I'll have a look, if it is that I can at least add a thread yield.

Ah yeh there's a busy GC collect loop at the end of run, I'll add a thread yield to that.

Also any error makes cli stuck instead of quiting, so I Ctlr-C every time

(again, you don't have to fix this 😉 )

Posted this on twitter. I guess that's where I stop for now.

Quick fix for the 100% CPU usage: https://github.com/Frassle/pulumi/commit/aa043378defb734f14e28672e92c8d5e9548bf94

just added a sleep 1ms to the collection loop (Which is need to trigger tasks to throw any uncaught errors)

Can't easily repro errors causing the cli to stick. If you have a small reproducer I can take a look but trying to pass invalid values, and throwing exceptions both in IO space and in the main program all seem to terminate ok.

Last time I got it when not passing mandatory parameters to cosmosdb:

new Pulumi.Azure.Cosmosdb.Account(
                "name",
                new Pulumi.Azure.Cosmosdb.AccountArgs()
                {
                    ResourceGroupName = resourceGroup.Name,
                    Location = resourceGroup.Location
                });

Or even not logging into azure

helpful-vegetable-35581

hmm odd both of those seem to terminate, must of been something more complex that triggers it

helpful-vegetable-35581

02/18/2019, 10:32 AM

ah well ctrl-c isn't a terrible workaround for now

sure, no worries

I was wondering, how would I go about adding support for a new language to pulumi. In this case I believe that (especially for Azure) a way to write this in PowerShell might be a really good way to get lots of adoption. I guess it's a matter of having a dotnet library first, right?

helpful-vegetable-35581

03/09/2019, 3:10 PM

I started a prototype for dotnet support, it's on hold waiting for the results of https://github.com/pulumi/pulumi/issues/2430

@helpful-vegetable-35581 just trying to understand what I needed to do to add language support. Does the pulumi binary expose something and I wrap my language around that?

stocky-spoon-28903

03/09/2019, 10:24 PM

@colossal-room-15708 Effectively yes - the Pulumi engine exposes a GRPC interface, and the runtime for the target language has to implement that

stocky-spoon-28903

03/09/2019, 10:25 PM

(Over)simplifying it, the program in the target language has to make calls to RegisterResource as it executes and objects are constructed

What is the pulumi engine?

microscopic-dusk-80789

03/21/2019, 1:51 AM

I see tons of references to it in the code, (grpc clients that connect to it) but I can't figure out what it is or where it gets created/spawned/ where the GRPC server starts listening

I am basically trying to do what this person was asking about: https://github.com/pulumi/pulumi/issues/2506

microscopic-dusk-80789

embed pulumi in my program

microscopic-dusk-80789

I want to write a tool will use pulumi to manage resources in AWS. I am familiar with Terraform and using Terraform was my 1st thought. but I like how pulumi is done with imperative style code and how you can write arbitrary code along with the bits that declare resources that should be managed

microscopic-dusk-80789

03/21/2019, 1:55 AM

I could write it as basically a client of the Pulumi command line, but I don't want to do that, because its seems... dirty

stocky-spoon-28903

What’s the reason for wanting to embed the engine instead of just using the

pulumi

CLI? Although it’s technically possible, it’s fairly complex because there is no API stability guarantee of the engine internals

microscopic-dusk-80789

03/21/2019, 1:56 AM

I have to admit, part of it is curiousity 🙂 this is a hobby project and I just naturally want to take things apart and see how they work

microscopic-dusk-80789

03/21/2019, 1:57 AM

There are some reasons, though. non-happy-path handling is done completely different for humans (cli users) versus machines There may be no api stability of the internals, but what about api stability of me parsing strings out of the CLI error messages?
