bors b3df526dc5 Auto merge of #5180 - alexcrichton:transitive-update, r=matklad ... Don't abort resolution on transitive updates This commit is directed at fixing #4127, allowing the resolver to automatically perform transitive updates when required. A few use casese and tagged links are hanging off #4127 itself, but the crux of the issue happens when you either add a dependency or update a version requirement in `Cargo.toml` which conflicts with something listed in your `Cargo.lock`. In this case Cargo would previously provide an obscure "cannot resolve" error whereas this commit updates Cargo to automatically perform a conservative re-resolution of the dependency graph. It's hoped that this commit will help reduce the number of "unresolvable" dependency graphs we've seen in the wild and otherwise make Cargo a little more ergonomic to use as well. More details can be found in the source's comments! Closes #4127		2018-03-15 15:22:32 +00:00
