Summary:
Recent versions of JavaScriptCore strip query strings from Error.prototype.stack, which breaks our use of query strings to carry bundle build parameters. See facebook/react-native#36794 for context.

This allows Metro to accept an alternative format where we interpret the special reserved character sequence ;&, the first time it appears in a URL path, as equivalent to ?.

So that this does not break custom rewriteRequestUrl implementations, we (temporarily) pass a normalised URL (;& replaced with ?), and then reverse that operation on the URL returned by rewriteRequestUrl. [Simplifying the details here somewhat - see the implementation for specifics].

Changelog:

**[Feature]**: Support alternative JavaScriptCore-safe URL format (`;&` as `?`).

Pull Request resolved: facebook#974

Recent versions of JavaScriptCore strip query strings from `Error.prototype.stack`, which breaks our use of query strings to carry bundle build parameters. See facebook/react-native#36794 for context.

This allows Metro to accept an alternative format where we interpret the special reserved character sequence `;&`, the first time it appears in a URL *path*, as equivalent to `?`.

So that this does not break custom `rewriteRequestUrl` implementations, we (temporarily) pass a normalised URL (`;&` replaced with `?`), and then reverse that operation on the URL returned by `rewriteRequestUrl`. *[Simplifying the details here somewhat - see the implementation for specifics].*
