At https://github.com/n8n-io/n8n/pull/8213 we introduced Redis hashes
for workflow ownership and manual webhooks...
- to remove clutter from multiple related keys at the top level,
- to improve performance by preventing serializing-deserializing, and
- to guarantee atomicity during concurrent updates in multi-main setup.
Workflow activation errors can also benefit from this. Added test
coverage as well.
To test manually, create a workflow with a trigger with an invalid
credential, edit the workflow's `active` column to `true`, and restart.
The activation error should show as a red triangle on canvas and in the
workflow list.

- Implement Redis hashes on the caching service, based on Micha's work
in #7747, adapted from `node-cache-manager-ioredis-yet`. Optimize
workflow ownership lookups and manual webhook lookups with Redis hashes.
- Simplify the caching service by removing all currently unused methods
and options: `enable`, `disable`, `getCache`, `keys`, `keyValues`,
`refreshFunctionEach`, `refreshFunctionMany`, `refreshTtl`, etc.
- Remove the flag `N8N_CACHE_ENABLED`. Currently some features on
`master` are broken with caching disabled, and test webhooks now rely
entirely on caching, for multi-main setup support. We originally
introduced this flag to protect against excessive memory usage, but
total cache usage is low enough that we decided to drop this setting.
Apparently this flag was also never documented.
- Overall caching service refactor: use generics, reduce branching, add
discriminants for cache kinds for better type safety, type caching
events, improve readability, remove outdated docs, etc. Also refactor
and expand caching service tests.

also refactored the code to
1. stop passing around `scope === 'global'`, since this code can be used
only for changing globalRole.
2. leak less details when input validation fails.

We're initializing the queue twice because of a [bad
merge](2c63474538).
No associated known bugs but no need to init the queue twice. We should
follow up by investigating if any pending bugs can be associated to
this.
Saving execution data is one of the slowest DB operations in the
application, and is likely behind some of the sqlite transaction
concurrency issues we've been seeing.
This not only remove the 2 separate transactions for saving
`ExecutionEntity` and `ExecutionData`, but also remove fields from
`ExecutionData.workflowData` that don't need to be saved (like `tags`,
`shared`, `statistics`, `triggerCount`, etc).
## Summary
Ensure `ownedBy` and `sharedWith` are present and uniform for
credentials and workflows.

### Manual workflow activation and deactivation
In a multi-main scenario, if the user manually activates or deactivates
a workflow, the process (whether leader or follower) that handles the
PATCH request and updates its internal state should send a message into
the command channel, so that all other main processes update their
internal state accordingly:
- Add to `ActiveWorkflows` if activating
- Remove from `ActiveWorkflows` if deactivating
- Remove and re-add to `ActiveWorkflows` if the update did not change
activation status.
After updating their internal state, if activating or deactivating, the
recipient main processes should push a message to all connected
frontends so that these can update their stores and so reflect the value
in the UI.
### Workflow activation errors
On failure to activate a workflow, the main instance should record the
error in Redis - main instances should always pull activation errors
from Redis in a multi-main scenario.
### Leadership change
On leadership change...
- The old leader should stop pruning and the new leader should start
pruning.
- The old leader should remove trigger- and poller-based workflows and
the new leader should add them.
This PR:
- Creates `InvitationController`
- Moves `POST /users` to `POST /invitations` and move related test to
`invitations.api.tests`
- Moves `POST /users/:id` to `POST /invitations/:id/accept` and move
related test to `invitations.api.tests`
- Adjusts FE to use new endpoints
- Moves all the invitation logic to the `UserService`

Story: https://linear.app/n8n/issue/PAY-926
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.
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 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.
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.

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.
