pulumi/pulumi-azure-native causes high memory usage

[rhuanbarreto]

Type: Bug

I have vs with almost no extensions enabled. Loading a TS file makes the initializing JS/TS language features to try for long time.

I enabled "typescript.tsserver.trace": "verbose" and this is the error:

TSServer exited. Code: null. Signal: SIGABRT

In my case it's an issue about the @pulumi/azure-native package that is huge to index by the TS language plugin.

pulumi/pulumi-azure-native#1997

Best solution was to remove the top level import and change it to importing from the subfolders according to this comment pulumi/pulumi-azure-native#932 (comment)

Increasing the memory for typescript for parsing it can also help but doesn't solve all the time. pulumi/pulumi-azure-native#1997 (comment)

But I really wish VScode could have a timeout option to increase its timeout for those specific cases of big libraries. Today the abort timeout is not configurable.

Thanks for investigating @rhuanbarreto! I've moved this over to TypeScript to see if there's anything that we can improve on the TS side (in addition to improvements to that package)

It sounds like server is running out of memory here. There's no specific timeouts for analyzing big libraries

[mjbvz]

Likely a duplicate of #50809 (comment) though (and sounds like the next steps are on pulumi)

[rhuanbarreto]

@mjbvz how can I profile memory usage from the ts server in vscode? I increased the memory size to 8192 and I have 64GB total but no help. I just want to find a sensible number here.

[mjbvz]

Unfortunately 4GB is the max memory at the moment regardless of any setting: microsoft/vscode#175792
