Data corruption in write.json when compiled

[zupat]

write.json seems to be changing keys that starts with an underscore _ . This only happens when executing the bytecode.

Minimal reproduction (repo):

git clone https://github.com/jinyus/arturo_bug_demo.git ;
cd arturo_bug_demo ;
./run.sh

Code

posts: read.json "./posts.json"

allPostIDs: map.with:'i posts 'p [
    #[
        "_id": get p "_id",
        "_index": i,
    ]
]

print write.json ø allPostIDs

Ouput:

Running arturo demo.art (correct)

[
    {
        "_id": "h5cwwbua",
        "_index": 0
    },
    {
        "_id": "jf0da9ku",
        "_index": 1
    }
]

Running arturo -x demo.art.bcode (modifying the key)

[
    {
        "id": "h5cwwbua",
        "index": 0
    },
    {
        "id": "jf0da9ku",
        "index": 1
    }
]

That's very interesting and tricky! I'll try to trigger it and will let you know.

This specific thing aside, one word of caution:

The ability to export-to and execute Bytecode directly has been around for quite some time, but I honestly haven't worked on it too much... so, even though it is there, I haven't really used it as a feature in production code. (to be interpreted as: I don't feel very confident about it, yet)

That being said, you're more than welcome to post all issues you come across, related to... anything. Since this is the only way to help the project make some progress! 😉 🚀

Hmmm... Curious
Inspecting the bytecode, we have got this:

[ :bytecode
        ================================
         DATA
        ================================
        0: ./posts.json :string
        1: json :attribute
        2: read :word
        3: posts :label
        4: [ :block
                # :symbol
                [ :block
                        _id :label
                        get :word
                        p :word
                        _id :string
                        _index :label
                        i :word
                ]
        ]
        5: p :literal
        6: i :literal
        7: with :attributelabel
        8: allPostIDs :label
        9: write :word
