We don't actually want the source mapped version of `.stack` from errors
because that would cause us to not be able to associate it with a source
map in the UIs that need it. The strategy in browsers is more correct
where the display is responsible for source maps.
That's why we disable any custom `prepareStackTrace` like the ones added
by `source-map`. We reset it to `undefined`.
However, when running node with `--enable-source-maps` the default for
`prepareStackTrace` which is a V8 feature (but may exist elsewhere too
like Bun) is a source mapped version of the stack. In those environments
we need to reset it to a default implementation that doesn't apply
source maps.
We already did this in Flight using the `ReactFlightStackConfigV8.js`
config. However, we need this more generally in the
`shared/ReactComponentStackFrame` implementation.
We could always set it to the default implementation instead of
`undefined` but that's unnecessary code in browser builds and it might
lead to slightly different results. For safety and code size, this PR
does it with a fork instead.
All builds specific to `node` or `edge` (or `markup` which is a server
feature) gets the default implementation where as everything else (e.g.
browsers) get `undefined` since it's expected that this is not source
mapped. We don't have to do anything about the equivalent in React
DevTools since React DevTools doesn't run on the server.
Normally we filter out stack frames with missing `filename` because they
can be noisy and not ignore listed. However, it's up to the
filterStackFrame function to determine whether to do it. This lets us
match `<anonymous>` stack frames in V8 parsing (they don't have line
numbers).
Stacked on #30401.
Previously we were transferring the original V8 stack trace string to
the client and then parsing it there. However, really the server is the
one that knows what format it is and it should be able to vary by server
environment.
We also don't use the raw string anymore (at least not in
enableOwnerStacks). We always create the native Error stacks.
The string also made it unclear which environment it is and it was
tempting to just use it as is.
Instead I parse it on the server and make it a structured stack in the
transfer format. It also makes it clear that it needs to be formatted in
the current environment before presented.
