Source code for for React 16.14.0?

[jrmuizel]

It seems like React 16.14.0 was published from a built version checked into the old_majors directory and then tagged with v16.14.0

old_major_packages/16/react/build-info.json references a commit da834083c that doesn't exist in the repo.

In the source code for this version available anywhere? If not, what's the closest approximation?

@jrmuizel is the still issue still available?...can you please assign it to me

Generally we tag the release versions:

https://github.com/facebook/react/commits/v16.14.0

The commit you mentioned also does exist in the repo:

https://github.com/facebook/react/commits/da834083c

[jrmuizel]

Yeah, I figured out that I wasn't fetching all the tags so that's why I was missing da83408.

However, it seems like v16.13.1 is da834083c

Further, when I build da83408, the artifacts that I get out don't match the package on npm.

Generally we tag the release versions:

https://github.com/facebook/react/commits/v16.14.0

This tag only has the built packages for 16.14.0 and not the source code.
i.e. v16.14.0, v15.7.0, 0.14.10 all point at the same revision: 4337c1c00609ec8d7ae399c736e9d37bb159fac5

[sophiebits]

I found this PR with a description of what happened: #20024

It sounds like since these were backports we didn't build entirely from source; rather we copied the previous release artifacts, bumped version numbers, and copied in the built JSX runtime from the 17.x branch.

Hope this helps (curious why you're asking).

[markerikson]

Ah. A few weeks ago I was backporting my build pipeline changes for sourcemaps ( #26446 ) to earlier versions. Worked fine for 18.2, 18.1, and 17.0.2, but the build artifact I generated for 16.14.0 was significantly different. That explains why.

[jrmuizel]

Hope this helps (curious why you're asking).

I was trying to rebuild react 16.14.0 with different minification settings.

[markerikson]

@jrmuizel : okay, now I'm curious :) Why are you trying to rebuild React 16? with what different minification settings? What's the goal?

[jrmuizel]

React 16 is used by the TodoMVC-React-Redux Speedometer 3 test. I wanted an unminifed version that was a close as possible to the production version to use for profiling.

[markerikson]

Ah, that sounds similar to what I've done with the sourcemap generation process.

Is there a reason why Speedometer is still using React 16 and not a newer version?
