@alexander-akait I think this could be acceptable for v5 change. The behavior today is technically a bug, although |

Update
RealContentHashPluginto initialize hash instances with the value ofoutput.hashSalt, if provided. This allows developers to use theoutput.hashSaltproperty to force all emitted webpack assets to have new hashes, even though the content has not changed, for example to deliberately cache break a CDN.Note that if the
optimization.realContentHashproperty was set tofalse, the value of[contenthash]already includedoutput.hashSaltin the calculation.What kind of change does this PR introduce?
Fix #16788
Did you add tests for your changes?
Yes. Changes verify that running three configs with identical source files and two different values of
output.hashSaltproduce exactly 2 unique output hashes.Does this PR introduce a breaking change?
This could be considered a breaking change if a consumer is using the
output.hashSaltproperty and depending on the value of[contenthash]not changing whenoptimization.realContentHashis set.Plugins that provide a custom implementation of the content hash (e.g. for Sub-Resource Integrity) will not be impacted, because this change only applies when the
RealContentHashPluginis the entity that generates the content hash.What needs to be documented once your changes are merged?
Documentation of
optimization.realContentHashshould be updated to explicitly call out that it does includeoutput.hashSaltif set. The current state of the documentation is unclear on whether or not it is expected.
