Bug: Files are incorrectly downloaded from OneDrive

[cardin]

Description

OneDrive allows users to put files online-only. I.e. they are downloaded on-demand when accessed.

If we have a Git Repository that is online-only, when Files accesses the folder, it will try to parse the .git/ directory and download all the files within.

This download process causes responsiveness issues as OneDrive tries to sync hundreds of blob files down.

Steps To Reproduce

1. Have a online-only OneDrive .git folder
2. Access that folder using Files
3. OneDrive sync notification will popup, showing multiple files downloaded
4. This causes Files and system slowdown, depending on network and hardware conditions

Requirements

• Files should not slow down or impact the system when accessing an online-only Git repository.

Files Version

2.5.10.0

Windows Version

10.0.19045.3086

Log File

No log files were generated by Files.

Thank you for your feedback, this definitely needs to be addressed.

@cardin can you repro this in v3.0.3?

[cardin]

can you repro this in v3.0.3?

@yaira2 Yes, reproed in Files Preview 3.0.3

Including the UI hanging and being responsive while the download is going on.

It doesn't even need to be a Git Repository with large blob files (<1Mb files), or long history (<2 git commit history).

[yaira2]

Can you repro this with the Files repo?

[cardin]

Yes it is reproducible with the Files repo
