FB bundles wrap warning() calls in __DEV__
Split dev-mode transforms into separate parts:
1) umd+cjs+fb: Wrap warning calls with process.env checks
2) umd+cjs: Replace error messages with minified codes
Also updated transforms to use __DEV__ since it transforms to smaller code after stripEnvVariables is run.
Also renamed 'scripts/error-codes/dev-expression-with-codes.js' -> 'scripts/error-codes/replace-invariant-error-codes.js'
* WIP Improve error message thrown in Fiber with multiple copies of React
**what is the change?:**
Adding an 'invariant' with detailed error message for the problem that
occurs when you load two copies of React with the Fiber reconciler.
WIP:
- Is there any other likely cause for this error besides two copies of
React?
- How can we make the message more clear?
Still TODO:
- Write a unit test
- Write a documentation page and create the link to the page, similar
to https://facebook.github.io/react/warnings/refs-must-have-owner.html
It would also be nice to have a page with instructions on how to fix
common cases of accidental double-loading of React, but we can open a
separate issue on that and let the community do it.
**why make this change?:**
This error comes up relatively often and we want to make things clear
when it happens in v16.0+
**test plan:**
WIP
**issue:**
Fixes#9962
* Add improved warning and docs for 'refs must have owner' in Fiber
**what is the change?:**
- Added warning in the place where this error is thrown in Fiber, to
get parity with older versions of React.
- Updated docs to mention new error message as well as old one.
I started to write a new docs page for the new error, and realized the
content was the same as the old one. So then I just updated the existing
error page.
**why make this change?:**
We want to avoid confusion when this error is thrown from React v16.
**test plan:**
- manually inspected docs page
- manually tested in a CRA to trigger the error message
(Flarnie will insert screenshots)
**issue:**
Fixes#9962
Related to #8854
* Add test for the informative warning around multiple react copies
@gaearon debugged the test for this and now it works!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :)
**what is the change?:**
We now test for the warning that the previous commits add in Fiber, and
also test for the old warning in the stack reconciler.
**why make this change?:**
This is an especially important warning, and we want to know that it
will fire correctly.
**test plan:**
`yarn test src/renderers/__tests__/multiple-copies-of-react-test.js`
`REACT_DOM_JEST_USE_FIBER=1 yarn test src/renderers/__tests__/multiple-copies-of-react-test.js`
* Fix up test for 'multiple copies of react'
**what is the change?:**
refactor test for 'multiple copies of React' to be simpler and remove
some copypasta
* run prettier
* Fix conditionals in 'multiple copies of react' test
**what is the change?:**
When moving the 'fiber' and 'non-fiber' conditions from two assertions
into one, we copy pasted the wrong message into the 'fiber' condition.
This wasn't caught because we were using an outdated name for the
'fiber' constant when running the tests locally with fiber enabled.
This fixes the copy-paste error and we now are actually running the
tests with fiber enabled locally.
* Run scripts/fiber/record-tests
* Blog post for 15.6.0

While reading the page, the "chain of thought" is broken by stating that the `tempertature` and `onTemperatureChange` don't have any special meaning. Making this a blockquote makes that note look more like a comment and keep the "chain of thought" intact.
