Cannot open file with sqlite

[kaleidawave]

I am trying the sqlite project with Wasmer. However any interactions with the file system seem to fail:

> wasmer run sqlite test.sl3
SQLite version 3.26.0 2018-12-01 12:34:55
Enter ".help" for usage hints.
sqlite> create table test (x int);
Error: unable to open database "test.sl3": unable to open database file

Any ideas, I thought WASI enabled file access...? (on windows btw)

You probably need to use mapdir to map current folder

[kaleidawave]

Can you elaborate, is that with the wasmer run --mapdir option...? Having the same for wasmer run python .\hello.py, which outputs cannot open '.\hello.py', [Errno 76] Capabilities insufficient.

Is there a flag like in Wasmer like Deno's --allow-read?

I'm also curious how to pass permissions to wasm program, searching for Capabilities in the docs doesn't yield anything

[sigmaSd]

I think its just not implemented yet, since wasmtime has the same error, but can pass permissions

Turns out its possible wasmer run --map-dir ".:." ./cp.wasm -- ./src/foo ./dest/bar
