This PR coordinates workflow activation on instance startup and on
leadership change in multiple main scenario in the internal API. Part 3
on manual workflow activation and deactivation will be a separate PR.
### Part 1: Instance startup
In multi-main scenario, on starting an instance...
- [x] If the instance is the leader, it should add webhooks, triggers
and pollers.
- [x] If the instance is the follower, it should not add webhooks,
triggers or pollers.
- [x] Unit tests.
### Part 2: Leadership change
In multi-main scenario, if the main instance leader dies…
- [x] The new main instance leader must activate all trigger- and
poller-based workflows, excluding webhook-based workflows.
- [x] The old main instance leader must deactivate all trigger- and
poller-based workflows, excluding webhook-based workflows.
- [x] Unit tests.
To test, start two instances and check behavior on startup and
leadership change:
```
EXECUTIONS_MODE=queue N8N_LEADER_SELECTION_ENABLED=true N8N_LICENSE_TENANT_ID=... N8N_LICENSE_ACTIVATION_KEY=... N8N_LOG_LEVEL=debug npm run start
EXECUTIONS_MODE=queue N8N_LEADER_SELECTION_ENABLED=true N8N_LICENSE_TENANT_ID=... N8N_LICENSE_ACTIVATION_KEY=... N8N_LOG_LEVEL=debug N8N_PORT=5679 npm run start
```
Due to a change, during the credentials import command, the core's
Credential object is being called through its prototype. This caused the
Credential's cipher variable to not be set, thus no cipher service being
available during import. This fix catches this edge case and provides a
fix.
https://linear.app/n8n/issue/PAY-933/set-up-leader-selection-for-multiple-main-instances
- [x] Set up new envs
- [x] Add config and license checks
- [x] Implement `MultiMainInstancePublisher`
- [x] Expand `RedisServicePubSubPublisher` to support
`MultiMainInstancePublisher`
- [x] Init `MultiMainInstancePublisher` on startup and destroy on
shutdown
- [x] Add to sandbox plans
- [x] Test manually
Note: This is only for setup - coordinating in reaction to leadership
changes will come in later PRs.
This PR converts the hard-deletion interval to a timeout:
- to prevent the interval from not being restored when hard deletion
throws, and
- to prevent a long-running hard deletion from leading to duplicate
deletions.
This change ensures that things like `encryptionKey` and `instanceId`
are always available directly where they are needed, instead of passing
them around throughout the code.
This is related to an issue with how Bull handles stalled jobs, see
https://github.com/OptimalBits/bull/issues/1415 for reference.
CPU intensive workflows can in certain cases take a long while to finish
up, thereby blocking the thread and causing Bull queue to think the job
has stalled, even though it finished successfully. In these cases the
error handling could then overwrite the successful execution data with
the error message.
This fixes a bug in the pruning (soft-delete). The pruning was a bit too
aggressive, as it also pruned executions that weren't in an end state
yet. This only becomes an issue if there are long-running executions
(e.g. workflow with Wait node) or the prune parameters are set to keep
only a tiny number of executions.
This PR adds a message for queue mode which triggers an external secrets
provider reload inside the workers if the configuration has changed on
the main instance.
It also refactors some of the message handler code to remove cyclic
dependencies, as well as remove unnecessary duplicate redis clients
inside services (thanks to no more cyclic deps)
all commands sent between main instance and workers need to contain a
server id to prevent senders from reacting to their own messages,
causing loops
this PR makes sure all sent messages contain a sender id by default as
part of constructing a sending redis client.

[PAY-837](https://linear.app/n8n/issue/PAY-837/implement-object-store-manager-for-binary-data)
This PR includes `workflowId` in binary data writes so that the S3
manager can support this filepath structure
`/workflows/{workflowId}/executions/{executionId}/binaryData/{binaryFilename}`
to easily delete binary data for workflows. Also all binary data service
and manager methods that take `workflowId` and `executionId` are made
consistent in arg order.
Note: `workflowId` is included in filesystem mode for compatibility with
the common interface, but `workflowId` will remain unused by filesystem
mode until we decide to restructure how this mode stores data.

Story: https://linear.app/n8n/issue/PAY-839
This is a longstanding bug, fixed now so that the S3 backend for binary
data can use execution IDs as part of the filename.
To reproduce:
1. Set up a workflow with a POST Webhook node that accepts binary data.
2. Activate the workflow and call it sending a binary file, e.g. `curl
-X POST -F "file=@/path/to/binary/file/test.jpg"
http://localhost:5678/webhook/uuid`
3. Check `~/.n8n/binaryData`. The binary data and metadata files will be
missing the execution ID, e.g. `11869055-83c4-4493-876a-9092c4708b9b`
instead of `39011869055-83c4-4493-876a-9092c4708b9b`.
Depends on: #7092 | Story:
[PAY-768](https://linear.app/n8n/issue/PAY-768)
This PR:
- Generalizes the `IBinaryDataManager` interface.
- Adjusts `Filesystem.ts` to satisfy the interface.
- Sets up an S3 client stub to be filled in in the next PR.
- Turns `BinaryDataManager` into an injectable service.
- Adjusts the config schema and adds new validators.
Note that the PR looks large but all the main changes are in
`packages/core/src/binaryData`.
Out of scope:
- `BinaryDataManager` (now `BinaryDataService`) and `Filesystem.ts` (now
`fs.client.ts`) were slightly refactored for maintainability, but fully
overhauling them is **not** the focus of this PR, which is meant to
clear the way for the S3 implementation. Future improvements for these
two should include setting up a backwards-compatible dir structure that
makes it easier to locate binary data files to delete, removing
duplication, simplifying cloning methods, using integers for binary data
size instead of `prettyBytes()`, writing tests for existing binary data
logic, etc.

Based on #7065 | Story: https://linear.app/n8n/issue/PAY-771
n8n on filesystem mode marks binary data to delete on manual execution
deletion, on unsaved execution completion, and on every execution
pruning cycle. We later prune binary data in a separate cycle via these
marker files, based on the configured TTL. In the context of introducing
an S3 client to manage binary data, the filesystem mode's mark-and-prune
setup is too tightly coupled to the general binary data management
client interface.
This PR...
- Ensures the deletion of an execution causes the deletion of any binary
data associated to it. This does away with the need for binary data TTL
and simplifies the filesystem mode's mark-and-prune setup.
- Refactors all execution deletions (including pruning) to cause soft
deletions, hard-deletes soft-deleted executions based on the existing
pruning config, and adjusts execution endpoints to filter out
soft-deleted executions. This reduces DB load, and keeps binary data
around long enough for users to access it when building workflows with
unsaved executions.
- Moves all execution pruning work from an execution lifecycle hook to
`execution.repository.ts`. This keeps related logic in a single place.
- Removes all marking logic from the binary data manager. This
simplifies the interface that the S3 client will meet.
- Adds basic sanity-check tests to pruning logic and execution deletion.
Out of scope:
- Improving existing pruning logic.
- Improving existing execution repository logic.
- Adjusting dir structure for filesystem mode.

This PR implements the updated license SDK so that worker and webhook
instances do not auto-renew licenses any more.
Instead, they receive a `reloadLicense` command via the Redis client
that will fetch the updated license after it was saved on the main
instance
This also contains some refactoring with moving redis sub and pub
clients into the event bus directly, to prevent cyclic dependency
issues.
PR adds a new field to the SourceControlPreferences as well as to the
POST parameters for the `source-control/preferences` and
`source-control/generate-key-pair` endpoints. Both now accept an
optional string parameter `keyGeneratorType` of `'ed25519' | 'rsa'`
Calling the `source-control/generate-key-pair` endpoint with the
parameter set, it will also update the stored preferences accordingly
(so that in the future new keys will use the same method)
By default ed25519 is being used. The default may be changed using a new
environment parameter:
`N8N_SOURCECONTROL_DEFAULT_SSH_KEY_TYPE` which can be `rsa` or `ed25519`
RSA keys are generated with a length of 4096 bytes.
This PR adds new endpoints to the REST API:
`/orchestration/worker/status` and `/orchestration/worker/id`
Currently these just trigger the return of status / ids from the workers
via the redis back channel, this still needs to be handled and passed
through to the frontend.
It also adds the eventbus to each worker, and triggers a reload of those
eventbus instances when the configuration changes on the main instances.
In scope:
- Consolidate `WorkflowService.getMany()`.
- Support non-entity field `ownedBy` for `select`.
- Support `tags` for `filter`.
- Move `addOwnerId` to `OwnershipService`.
- Remove unneeded check for `filter.id`.
- Simplify DTO validation for `filter` and `select`.
- Expand tests for `GET /workflows`.
Workflow list query DTOs:
```
filter → name, active, tags
select → id, name, active, tags, createdAt, updatedAt, versionId, ownedBy
```
Out of scope:
- Migrate `shared_workflow.roleId` and `shared_credential.roleId` to
string IDs.
- Refactor `WorkflowHelpers.getSharedWorkflowIds()`.
Changes in https://github.com/n8n-io/n8n/pull/6394 removed xml body parsing for all non-webhook routes. This broken SAML endpoints as they need the XML body parser to function correctly.

* refactor(core): Move webhook DB access to repository (no-changelog)
* make sure `DataSource` is initialized before it's dependencies
at some point I hope to replace `DataSource` with a custom `DatabaseConnection` service class that can then disconnect and reconnect from DB without having to update all repositories.
