Thank you very much for addressing this, @noahtallen! One question: My typical scenario is that I'd like to work on Gutenberg while offline. Its default Line 2 in 9bd56dc It seems that this isn't currently supported by this PR, correct? (Only empty or missing |

BTW -- unrelated to my other question -- do I need to destroy my existing wp-env environment to test the following?
I'm asking because if I change my (and so on). This is apparently unrelated to the PR as it seems to happen on |
That should work with this branch! As long as the environment was already created once, The check for the latest WordPress version only happens when "core" doesn't exist. So that function isn't called otherwise. But even after fixing that issue, I needed to prevent You can also override "core" with your own |

Hey @noahtallen, apologies for not getting back to you sooner!
I just re-tested this offline, without changing my .wp-env.json, i.e. without removing the core field. This time around, it worked smoothely 🎉
LGMT then! 🚢 Thanks again for implementing this change!

What?

Fixes #52157.
Unfortunately, many
wp-envcommands don't work without internet due to a function which finds the latest WordPress version, which happens during config parsing. Beyond this function,wp-env startcould fail in many cases when it tries to do updates (like downloading sources or pulling docker images).Why?
Offline mode always has its uses!
How?
dns.resolve( 'WordPress.org' )to check for internet access. This seems to be a reasonable practice based on my search for how to do this with NodeJS. It's also very fast, which isn't the case when we wait for timeouts in other functions.shouldConfigureWplogic duringwp-env start, since most of that involves internet connections (pulling docker images, downloading sources, etc.) I think it's easier to do this than to add extra checks all over the place when we do something with the network.The side effect is that certain types of
wp-env.jsonupdates won't work if you're offline, but that seems like a reasonable compromise. For example, if you set thephpVersion, that involves downloading a different docker image. So a lot of the config options would be impacted anyways.Testing Instructions
corefrom Gutenberg's.wp-env.jsonfile to trigger the check for the latest core source.npx wp-env startnpx wp-env install-pathnpx wp-env run cli bashnpx wp-env run cli phpunit --versionAll should work.
