@roblourens Can you check if that folder exists for you? /Users/roblou/Library/Application Support/Code - Insiders/CachedData/c348be666adf9650b1ae1d212f019e6e9f226b7d should really be there...

That is weird... It means that we have generated cached data that we are now not accepting... This one is the file 'binding.js' for which we only happened to have one (the binding-npm-module) and which is used by spdlog...

Two possibilities

• two or mores processes (shared and exthost) generate different data for the same JS input file
• one process reads the cached data file when it's not yet fully written

both would cause a rejection and subsequent deletion of the file in question. Question is which of them causes this...

@roblourens Can you reproduce this or does this just happen once in a while? Also cc @chrmarti who has reported a similar issue...

[chrmarti]

This seems to happen quite regularly on my machine.

[jrieken]

Hm... This also happens when having an 'atomic' save logic (write to tmp, then rename)

[roblourens]

I see it today too, and the directory with the new hash does exist.

[roblourens]

It happens every time I reload the window:

[jrieken]

The problem must be that different instances of V8 read the same data but don't accept it. We don't really know why that is and what makes V8 reject data. I have pushed a change that adds a static name seed to each loader instance so that cached data isn't shared anymore between different loader-instances. This roughly adds 50 files to the cached data dir, but with that change I cannot reproduce this issue...
