Jsoo: postMessage, read back, conditions for safely doing so

[zeroexcuses]

Suppose we have two jsoo programs running and talking to each other via postMessage. (This could be two iframes or a index.html + a webworker).

Under what conditions, can we safetly postMessage an OCaml value and read it on the other side ?

Pre-emptive: “Why don’t you just use json” ? Answer: we have embedded typedArrayBuffers.

1. Thanks; agreed, it’s basically the same question.

2. Did you ever solve this ? It was not clear to me from the followups whether you solved it.

I’m just wondering if anyone has experience with webworkers. I’m getting miserable performance (70s) using them in contrast to blocking the page UI thread (3s), even if I subtract the data transfert overhead of 2-3s, that still seems a bit egregious.

Yes, see this message. Basically I had a stub “nil” value against which I was physically testing. You can’t do that in this setting your “nil” will get different addresses in each “process”.
