使用CLJS编写的Firefox插件无法通过Mozilla的审查

Question

大家好，
我有一个经过高级优化的clid Firefox插件，提交后，审查告诉我，我提交的zip文件与他们从源代码构建的不同。

我用diff-so-fancy比较生成的js文件，发现主要区别是变量名。

那么有没有什么办法可以确保生成的js是可重复的？

几年前，我有一个类似的问题（在我的情况下是为了更好的缓存），但至少当时答案是“不”。但是，您可以尝试使用优化设置为simple进行构建。它也会进行一些重命名，但我认为它是稳定的。如果这不起作用，应该使用whitespace。

Comments

neither `:simple` nor `:whitespace` are guaranteed to be deterministic, either. Much of the randomness comes from CLJS `gensym` using an ever increasing global integer.

But `gensym` is not random. Is there random ordering then? Where does it come from?

---

Compilation order/timing is non-deterministic in multi-threaded builds (default in shadow-cljs), as things get compiled in parallel. It might also be affected if caches are involved, as that changes what is compiled in the first place.

---

Does it mean that using a single-threaded build (if that's an option) along with purging the cache would solve the OP's problem?

I haven't looked at all randomness in builds, just the most obvious ones. So, possible but potentially no.
