Preview completed AFAICT
It still shows a bunch of deletes queued up as a result - would that happen if I ran up instead? I guess I'll have to try an actual update, once I can work out why it now hangs, and see what happens.
b
are you using a pre-release version?
w
Yes, latest alpha.
Basically, I ran preview with forced error, then I ran preview again which has hung - still spinning 25m later.
b
I would like to verify that the latest alpha includes the changeset that I made
It says it went out 2 hours ago but I don't know what commit it was built from
w
I can navigate to source and see your changes
b
well I'm not sure why it would be hanging, especially on preview
was this an existing stack? Did you by chance already have pending deletes in it?
w
It was an existing stack that was fully baked. All I did was tweak it to force an error.
b
well if you can get a repro let me know
w
Still hanging. Strange it hasn't timed out.
Had to kill the debug session:
Copy code

@bored-oyster-3147 debugging into it it seems the exception is never thrown
i.e. it returns a preview result
b
what does 
LocalRuntimeService
look like
that implies there was no 
CommandException
w
@bored-oyster-3147 
_callerContext.ExceptionDispatchInfo is null
Want to do a quick interactive session to debug it while I share my screen in slack?
b
I'm busy at the moment - is that EDI instance null? that would cause an exception to not be thrown
do you by chance have anything in your inline program that would cause the exception to not bubble out of it?
w
No, not catching at that scope.
b
but the EDI instance is still null?
w
Deployment.Runner.WhileRunningAsync.HandleCompletion
sees the exception, which is 
Scriban.Syntax.ScriptRuntimeException
Calls 
HandleExceptionAsync
which logs it and returns 32 
Deployment.RunInlineAsync
then has 
null
exceptionDispatchInfo
and returns 1 in lambda, returns 
null
at end 
LanguageRuntimeService.Run
then returns 
new RunResponse()
b
what is different about this exception
is it thrown in an apply or something?
w
It does happen inside 
Output.Create
b
and are you using a inline program delegate or the generic TStack?
w
Copy code
// gateways
new ConfigGroup("internal-gateway",
    new ConfigGroupArgs { Yaml = RenderTemplate("InternalGateway.yaml", ReadResource, new { Aws = AwsConfig }) },
    new ComponentResourceOptions { Provider = k8sProvider });
new ConfigGroup("internet-gateway",
    new ConfigGroupArgs { Yaml = RenderTemplate("InternetGateway.yaml", ReadResource, new { Aws = AwsConfig }) },
    new ComponentResourceOptions { Provider = k8sProvider });
I'm deriving from 
Pulumi.Stack
(not directly)
ConfigGroupArgs.Yaml
is 
InputList<string>
RenderTemplate
returns 
Output<string>
b
so you are using 
PulumiFn.Create<TStack>
?
w
Yes... 
PulumiFn Create(IServiceProvider serviceProvider, Type stackType)
Copy code
var stackName = $"{Config.Pulumi.Organization.Name}/{settings.Environment.ToLower()}";
var stackArgs = new InlineProgramArgs(info.ProjectName, stackName, PulumiFn.Create(ServiceProvider, info.StackType))
{
    Logger = LoggerFactory.CreateLogger<Pulumi.Deployment>()
};
var stack = await LocalWorkspace.CreateOrSelectStackAsync(stackArgs);
b
so not 
PulumiFn.Create<TStack>
ok just making sure I'm looking in the right place
w
No, the stack type is selected based on the "resources" to deploy, so not using the generic method.

OK I have a failing test

My gut feel is 
Pulumi.Deployment.Runner.RunAsync
and 
WhileRunningAsync
are swallowing the exception when they should not: https://github.com/pulumi/pulumi/blob/258fb00bc2ecbd489af6d694a2204468cc7ca729/sdk/dotnet/Pulumi/Deployment/Deployment.Runner.cs#L61-L64 https://github.com/pulumi/pulumi/blob/258fb00bc2ecbd489af6d694a2204468cc7ca729/sdk/dotnet/Pulumi/Deployment/Deployment.Runner.cs#L179-L183 i.e. the try catch should be removed or rethrow (They do log the exception so maybe not removed)
Then any immediate exceptions in the stack ctor, or deferred via outputs, should propagate and be captured.
b
yes exceptions in the in-flight tasks are being swallowed
w
And finally 
LanguageRuntimeService.Run
where it would no longer be 
null
and so return the "bail" response: https://github.com/pulumi/pulumi/blob/258fb00bc2ecbd489af6d694a2204468cc7ca729/sdk/dotnet/Pulumi.Automation/Runtime/LanguageRuntimeService.cs#L61
The bail response only sets the exception message, so the inner exception handler should still be called to log the full exception and rethrow.
b
I went about it a little differently. Namely because 
IRunner
is used by local programs too, and rethrowing in 
IRunner
would cause other issues there
w
Sounds good. I think we understand it either way.
b
Also because the main issue here was the exit code not being threaded through for inline programs. At the very least we should've seen 
CommandException
without an inline host exception, which was the first thing I fixed. Then needed to do some work to capture an aggregate of in-flight exceptions so that the explicit exception could bubble up
what a pain in the ass though. Me not touching 
Deployment_Runner
sooner coming back to bite me
Glad you caught that!

FWIW, I like your fix. LGTM.

That PR to fix the swallowed exceptions was merged btw!
w
Yeah, I'm already using the latest alpha. Much better now!
