PureCloudPlatformClientV2 slow or fails to load in my VSCode

joel_hellman · August 27, 2023, 5:51pm

PureCloudPlatformClientV2 have always been very slow for my IDE (VS Code) to autocomplete, but recently I upgraded from 127.0 to 182.0 and now its barely functional.

After a short while, my Pylance memory heap exceeds 2GB, and is restarting, also affecting the rest of my python project.

Here is a description for some other python packages with seems to fit my issue with this SDK package:

github.com/microsoft/pylance-release

Pylance runs out of memory while scanning files in workspace

## Environment data - Language Server version: 2023.3.20 - OS and versio…n: macOS Monterey, but running language server remotely via SSH (on a Debian GNU/Linux box in AWS) - Python version: 3.9 ## Repro Steps Sadly I don't have repro steps 😞 -- it's quite a large private repo. ## Expected behavior Pylance hits a 2GB heap limit after loading just about 700 files from a private repo, which I'd estimate is under a million lines of code. I would expect Pylance to allow you to increase the memory limit up to, say, 8GB or 16GB. I am not 100% sure this would fix the problem, but it makes sense that users might want to hold more than 2GB of type information in a single workspace. FWIW, it is possible to load this repo into Pycharm, although it's required that you up the memory limit to 8GB from Pycharm's default of 4GB. If that doesn't help, I'd also expect to be able to _fully ignore_ whole packages outside of my particular area. Even though I've set `python.analysis.include` to my own team's directory, Pylance still crawls the entire dependency tree of all of my files. ## Actual behavior Pylance provides no way to increase the limit above 2GB (at least not that I can find). I have tried adding `export NODE_OPTIONS="--max-old-space-size=8192"` to my `.bashrc` but that didn't change anything. ## Logs I've redacted the file names from the repo in this snippet, but it should give an idea. The main thing to notice here is there are no "whale" files that are blowing it up, it's just hundreds of reasonably sized files that all need to be loaded.

This is the only package where I have this issue. Looking into the code in the SDK, it seems pretty massive. Is there anything you can do to mitigate this issue?

I have my "python.analysis.diagnosticMode" set to "openFilesOnly", not "workspace". The issue starts whenever I need touch an object in PureCloudPlatformClientV2.

Hi hellman,

Can you let me know, your system information like the os you are currently using, Ram of the pc and the version of vscode ?

Hi @joel_hellman Can you give more information on the environment you are running this. Vs code Version, OS , RAM

Looks like we cannot extend memory foot print for Pylance directly but did you try adding more memory to the background process NODE_OPTIONS="--max-old-space-size=8192 ? This could help the cause.

Also did you try Jedi and do you see the same error when using both pylance and Jedi ?

Best Regards
Hemanth
