[rubygems/rubygems] Simulate Bundler 4 in a better way 2025-06-25T23:06:48+00:00 David Rodríguez deivid.rodriguez@riseup.net 2025-06-18T20:08:32+00:00 90085f62fb793f47e43b64acf6a32900ba8e6e4d Overriding the version constant feels too magic and creates a set of problems. For example, Bundler will lock the simulated version, and that can cause issues when the lockfile is used under an environment not simulating Bundler 4 (it will try to auto-install and auto-switch to a version that does not exist). On top of that, it can only be configured with an ENV variable which is not too flexible. This commit takes a different approach of using a setting, which is configurable through ENV or `bundle config`, and pass the simulated version to `Bundler::FeatureFlag`. The real version is still the one set by `VERSION`, but anything that `Bundler::FeatureFlag` controls will use the logic of the "simulated version". In particular, all feature flags and deprecation messages will respect the simulated version, and this is exactly the set of functionality that we want users to be able to easily try before releasing it. https://github.com/rubygems/rubygems/commit/8129402193

[rubygems/rubygems] Allow enabling "Bundler 3 mode" more easily

Currently to test Bundler 3 mode we have to actually edit the version
file to simulate we're running a future version. This is inconvenient.

Instead, allow passing an environment variable, `BUNDLER_3_MODE`, to set
the "working mode" Bundler should use.

This can now be set easily by end users to enable them to try out the
changes in the future version and give us feedback.

It's unclear how version auto-switching should work when this
environment variable is set, so the auto-switching feature will be
disabled in that case.

There's no reason why we should not update bundler as requested, even if
restarts are disabled.
