test(i): Add cross-version P2P test multiplier - #5174
Conversation
Setting up a test node took a function that returned networking options, so networking was the only thing a test could say about a node. When nodes needed to run from an older release, the version had nowhere to go and became its own separate action that the harness handled alongside the first one. Both are replaced by a single struct holding the version and the networking config as ordinary fields. The function that builds a random networking config now returns that struct, so the several hundred places that use it are unchanged. The two tests that asked for an older node were updated by hand. The harness now looks for one thing instead of two in four places, and the two setup functions became one that checks whether a version was given. Starting a node is untouched.

| Layer / File(s) | Summary |
|---|---|
Cross-version matrix and test configuration .github/workflows/test-coverage.yml, tests/multiplier/*, tests/action/acp_dac_config.go, tests/integration/utils.go, tests/integration/net/simple/... |
Cross-version multipliers assign v1.0.0 to either source direction. Coverage runs both variants. Restart scenarios exclude incompatible external-node variants. ACP selection uses shared package configuration. |
External-node startup configuration tests/action/node_setup.go, tests/clients/external/* |
External-node settings are translated into wrapper flags. Unsupported settings skip tests. The wrapper accepts caller-provided flags. |
Node-aware assertions and retry actions tests/state/state.go, tests/action/assert_request.go, tests/action/results.go, tests/action/eventually* |
Assertions select comparison behavior by node. Eventually retries failed assertion actions while preserving state, panic behavior, and the original test handle. |
External-node token audience validation tests/state/identity.go, tests/state/identity_test.go, tests/action/identity.go, tests/integration/identity.go |
Token audience checks decode JWT claims and regenerate tokens when the current external-node audience is absent. |
External-node event and head tracking tests/action/utils_events.go, tests/action/wait_for_peer_events.go, tests/integration/events.go |
External nodes record expected heads and poll commits or documents when event buses are unavailable. |
Cross-version scenario validation tests/integration/net/simple/peer/*, tests/integration/net/simple/replicator/* |
Cross-version update tests poll older nodes for replicated data. Restart tests exclude external-node variants that cannot reopen prior stores. |
Estimated code review effort: 4 (Complex) | ~60 minutes
Merge Risk: 🟠 High · up to 227df
The change adds CI jobs that download and execute an older release over plain HTTP, while synchronization gaps can let stale or incomplete data satisfy compatibility tests. This creates a significant merge-readiness and CI security risk that should be addressed before merging.

In @.github/workflows/test-coverage.yml:
- Around line 391-449: Harden both cross-version jobs by adding explicit
least-privilege permissions, configuring each actions/checkout step with
persist-credentials disabled, and updating the setup-defradb flow to download
the release binary over HTTPS with pinned checksum or signature verification
instead of plain HTTP.
In `@tests/action/utils_events.go`:
- Around line 151-179: Preserve collection-level head synchronization for
external nodes: in tests/action/utils_events.go lines 151-179, update the
MarkDocsExpectedOnTargets-related flow around latestCompositeCID and
updateConnectedNodes to record and propagate the branchable collection head
alongside document heads, or explicitly skip scenarios requiring that
synchronization. In tests/integration/events.go lines 367-372, update
waitForHeadsOnNode to poll and validate collection-level pending heads instead
of discarding non-document keys.
In `@tests/integration/events.go`:
- Around line 480-488: The error-handling branch in the result.GQL.Errors loop
must not return true for errCollectionVersionNotFound, because that can accept
an older document as the requested CID. Replace this shortcut with a query that
confirms the target update is readable, or skip the unsupported version pair;
only report arrival after the requested CID is actually verified.
In `@tests/multiplier/cross_version.go`:
- Around line 21-22: Update the cross-version registrations in the multiplier
setup so each job’s versioned node matches its scenario role: the old-source job
must target the write-source/replicator node used by
TestP2POneToOneReplicatorDeletesDocAddedBeforeReplicatorConfigWithNodesInversed,
and the new-source job must target the opposite node; adjust oldNodeFirst or the
job names accordingly.

Learning: In sourcenetwork/defradb code reviews, do not raise findings that are likely compiler/type-check errors (e.g., code that would fail `go test`/`go build`) because CI pipelines will catch compilation failures. Only flag compilation-related problems if there is a clear, verifiable issue beyond what CI will already surface (e.g., a mismatched build tag or missing generated artifact that CI would not cover).

Preserve collection-level head synchronization for external nodes.
Native update handling adds a collection ID expectation for branchable collections. MarkDocsExpectedOnTargets records only document IDs, and waitForHeadsOnNode discards non-document keys. Therefore, collection-version updates can bypass WaitForSync when either side is external.
tests/action/utils_events.go#L151-L179: record and propagate the branchable collection head with the document heads, or skip external scenarios that require collection-version synchronization.tests/integration/events.go#L367-L372: poll or otherwise verify collection-level pending heads. Do not silently discard them.

Do not treat errCollectionVersionNotFound as CID confirmation.
If the target already has an older document version, this branch returns true without confirming target. Then hasDoc can succeed on the older document, and Line 409 records the requested CID as the actual head. WaitForSync can complete before the update arrives.
Use a query that proves the requested update is readable, or skip this unsupported version pair. Do not mark the expected CID as arrived from this error alone.

Align cross-version jobs with the source node.
TestP2POneToOneReplicatorDeletesDocAddedBeforeReplicatorConfigWithNodesInversed uses node 1 as the replicator and write source. CrossVersionOldSource versions node 0, while CrossVersionNewSource versions node 1. The job names therefore describe the opposite data-flow direction.
Derive the versioned node from the scenario role, or rename the jobs to describe node position.

No blockers from me. I'm curious on your thoughts about making the event bus public.

thought: We could add the event bus to the client API. It could be useful for other use cases as well.

I thought it was public 😁 The event package is public, so it might have been public at one point. It is public to DB, and I would fully support it being public when the concrete DB becomes public.
It might have been made private due to the effort required to make it work via the remote clients.

@AndrewSisley Would you also support adding it to HTTP, CLI and other clients? That would allow the tests to work the same across embedded and external clients.

I would. Originally I started writing in my first message that those clients have subscriptions for this, but there is a difference between the two.
Although embedded also have subscriptions, and IIRC some effort was made into making it work nicely for embedded clients for v1 - so there's a very good argument to be made that we already have the main problem that I am concerned about for the remote clients.
Which is that I would prefer to not to confuse users by offering them too many ways to do something, and I would also like to not have to bother maintaining both.
However, I think events is to subscriptions what the collection API is to the rest of GQL. And I think my idealised Defra architecture would be collection API and events at the bottom, core stack, with planner, GQL and subscriptions sat on top of that. And so structurally, it makes sense. From a users perspective, it could be seen as odd not to expose it via the remote clients, but otherwise I have no good arguments for or against it atm I think.
Sorry if my reply is a bit confusing, I'm not entirely sure how I feel, and I think the current Defra architecture blends too many layers together making it difficult to provide a technically-definite answer.

I partially reviewed a few days ago but saw that the new multipliers do not seem to work in the CI. Please make sure they do, and please make them required.

We discussed with Andy in DM he is against merging another change that will cause one more failing job but this stuff is flaky and this is the next thing i'm planning to address and and Andy said explicitly that he will not block the merge so i'm just dismissing because he forgot to remove the block

Description
We had no automated check that a change keeps working against nodes running an older release, only two hand-written smoke tests. This reruns the existing networked suite with one node on v1.0.0, so the tests we already have double as the compatibility check. Both directions run as separate CI jobs, because they fail differently: a new node sending to an old one relies on the old node ignoring fields it does not know, while the reverse relies on the new node reading a missing field as a zero value.
Most of the work turned out to be in the test harness rather than the multiplier. A node running in another process has no event bus the test can watch, and the harness learns what to expect by watching event buses, so waits returned immediately and assertions ran against data that had not arrived yet. The source node is now asked for the head it just wrote, which feeds the same bookkeeping the in-process path already uses.
Restarting a node in another process is excluded for now, since it comes back with a new identity and cannot read what it wrote. Tracked in #5170
Tasks
How has this been tested?
Unit tests for the rewriting and the skip logic, which download nothing. The whole networked suite three ways, natively and in both directions against a real v1.0.0 binary, all at zero failures.
To confirm it detects a break rather than passing by construction, I renamed the replicator communication channel on the current build: the existing suite caught two failures, the cross-version runs caught thirteen more.
