## Summary
Fix how devtools handles URLs. It
- cannot handle relative source map URLs `//# sourceMappingURL=x.map`
- cannot recognize Windows style URLs
## How did you test this change?
works on my side
Stacked on https://github.com/facebook/react/pull/29869.
## Summary
When using ANSI escape sequences, we construct a message in the
following way: `console.<method>('\x1b...%s\x1b[0m',
userspaceArgument1?, userspaceArgument2?, userspaceArgument3?, ...)`.
This won't dim all arguments, if user had something like `console.log(1,
2, 3)`, we would only apply it to `1`, since this is the first
arguments, so we need to:
- inline everything whats possible into a single string, while
preserving console substitutions defined by the user
- omit css and object substitutions, since we can't really inline them
and will delegate in to the environment
## How did you test this change?
Added some tests, manually inspected that it works well for web and
native cases.
`_debugSource` was removed in
https://github.com/facebook/react/pull/28265.
This PR migrates DevTools to define `source` for Fiber based on
component stacks. This will be done lazily for inspected elements, once
user clicks on the element in the tree.
`DevToolsComponentStackFrame.js` was just copy-pasted from the
implementation in `ReactComponentStackFrame`.
Symbolication part is done in
https://github.com/facebook/react/pull/28471 and stacked on this commit.
Depends on:
- #28317

There's a ton of overlap between the createElement implementation and
the JSX implementation, so I combined them into a single module.
In the actual build output, the shared code between JSX and
createElement will get duplicated anyway, because react/jsx-runtime and
react (where createElement lives) are separate, flat build artifacts.
So this is more about code organization — with a few key exceptions, the
implementations of createElement and jsx are highly coupled.

## Summary
Fixes https://github.com/facebook/react/issues/24781
Restricting from editing props, which are class instances, because their
internals should be opaque.
Proposed changes:
1. Adding new data type `class_instance`: based on prototype chain of an
object we will check if its plain or not. If not, then will be marked as
`class_instance`. This should not affect `arrays`, ..., because we do
this in the end of an `object` case in `getDataType` function.
Important detail: this approach won't work for objects created with
`Object.create`, because of the custom prototype. This can also be
bypassed by manually deleting a prototype ¯\\\_(ツ)_/¯
I am not sure if there might be a better solution (which will cover all
cases) to detect if object is a class instance. Initially I was trying
to use `Object.getPrototypeOf(object) === Object.prototype`, but this
won't work for cases when we are dealing with `iframe`.
2. Objects with a type `class_instance` will be marked as unserializable
and read-only.
## Demo
`person` is a class instance, `object` is a plain object

## Summary
This PR:
- Replaces the existing usages of methods from the `semver` library in
the React DevTools source with an inlined version based on
https://www.npmjs.com/package/semver-compare.
This appears to drop the unminified bundle sizes of 3 separate
`react-devtools-extensions` build artifacts by about 50K:
## How did you test this change?
I was originally working on [a fork of React
DevTools](https://github.com/replayio/react/pull/2) for use with
https://replay.io , specifically our integration of the React DevTools
UI to show the React component tree while users are debugging a recorded
application.
As part of the dev work on that fork, I wanted to shrink the bundle size
of the extension's generated JS build artifacts. I noted that the
official NPM `semver` library was taking up a noticeable chunk of space
in the bundles, and saw that it's only being used in a handful of places
to do some very simple version string comparisons.
I was able to replace the `semver` imports and usages with a simple
alternate comparison function, and confirmed via hands-on checks and
console logging that the checks behaved the same way.
Given that, I wanted to upstream this particular change to help shrink
the real extension's bundle sizes.
I know that it's an extension, so bundle size isn't _as_ critical a
concern as it would be for a pure library. But, smaller download sizes
do benefit all users, and that also includes sites like CodeSandbox and
Replay that are using the React DevTools as a library as well.
I'm happy to tweak this PR if necessary. Thanks!
The old version of prettier we were using didn't support the Flow syntax
to access properties in a type using `SomeType['prop']`. This updates
`prettier` and `rollup-plugin-prettier` to the latest versions.
I added the prettier config `arrowParens: "avoid"` to reduce the diff
size as the default has changed in Prettier 2.0. The largest amount of
changes comes from function expressions now having a space. This doesn't
have an option to preserve the old behavior, so we have to update this.

Adds a side-bar to the profiling tab. Users can now select an update event, and are
shown the callstack from the originating component. When a source path is available
there is now UI to jump to source.
Add FB enabled feature flag: enableProfilerComponentTree for the side-bar.

This PR adds the reactVersion pragma to tests.
Tests without the reactVersion pragma won't be run if the reactVersion pragma isn't specified.
Tested each React version manually with the pragma to make sure the tests pass
Fixes#24302 based on #24306.

The current implementation for strict mode double logging stringiness and dims the second log. However, because we stringify everything, including objects, this causes objects to be logged as `[object Object]` etc.
This PR creates a new function that formats console log arguments with a specified style. It does this by:
1. The first param is a string that contains %c: Bail out and return the args without modifying the styles. We don't want to affect styles that the developer deliberately set.
2. The first param is a string that doesn't contain %c but contains string formatting: `[`%c${args[0]}`, style, ...args.slice(1)]` Note: we assume that the string formatting that the developer uses is correct.
3. The first param is a string that doesn't contain string formatting OR is not a string: Create a formatting string where:
- boolean, string, symbol -> %s
- number -> %f OR %i depending on if it's an int or float
- default -> %o

* ensure getDisplayName is only called on functions
* add SuspenseList to Dev tools element names
* Add SuspenseList and pass tests
* Import SuspenseList directly
* run prettier
* Refactor tests to use real components
* run linter
* [react-devtools-shared] Added string type check for object name prop in getDisplayName function from utils.js file; tests included;
* Re-added empty string check to getDisplayName()
* Tweaked tests to use real functions
This more closely simulates how the utility is being used in production, and would catch cases like anonymous functions (with empty string names).
