Supports GAUGE (overwrite) and COUNTER (increment) types with optional period bucketing (day/week/month) for time-series tracking. - Core model with period-aware ID generation - Embedded DB and PostgreSQL implementations - RPC messages, handlers with executor ownership auth - Client SDK and CLI commands (metrics ls/get/history/rm) - Comprehensive tests for both DB backends ---

Other entity types (processes, process graphs, generators) +may have similar patterns. A generic solution prevents future bugs. + +### Design + +Add a single `sync.RWMutex` to `EmbeddedDatabase`: + +```go +type EmbeddedDatabase struct { + mu sync.RWMutex // database-level transaction lock + // ... existing fields +} +``` + +**Write methods** acquire `db.mu.Lock()` and use normal store methods (which still +acquire their own internal locks): + +```go +func (db *EmbeddedDatabase) AddExecutor(executor *core.Executor) error { + db.mu.Lock() + defer db.mu.Unlock() + existing, ok := db.executors.Get(...) // store lock held internally + ... + db.executors.Put(...) // store lock held internally +} +``` + +**Read methods** -- most do NOT need `db.mu.RLock()`. A single-store read (e.g., +`GetExecutorByID` doing one `Get()`) is already atomic via the store's internal lock. +Only reads that span multiple stores and need cross-store consistency would need +`db.mu.RLock()`. In practice, very few reads fall into this category. + +### Why keep store-level locks + +The plan originally proposed removing store-level locks once `db.mu` is in place +(since `db.mu` makes them redundant). This is **wrong** -- the background flusher +runs on its own goroutine and calls `Store.FlushDirty()`, which uses the store's +internal lock to iterate dirty records. Without store locks, flusher iteration +would race with `Put()` modifications to the dirty set. + +Keeping both lock layers: +- `db.mu` provides transaction-level atomicity for multi-step writes +- Store locks protect internal data structures (maps, dirty tracking) for the flusher +- Lock ordering is naturally safe: `db.mu` always acquired first, store locks inside +- Double-locking in-memory maps has negligible overhead + +### Why not MVCC + +MVCC (Multi-Version Concurrency Control) would require versioned records, snapshot +isolation, conflict detection, garbage collection, and a transaction manager. This is +a substantial rewrite of the Store layer -- essentially building a mini database engine. + +The RWMutex approach trades some write concurrency for simplicity: +- Reads are unaffected (no RLock needed for single-store reads) +- Writes serialize (Lock exclusive), but are fast (in-memory maps, microseconds) +- Zero deadlock risk (single lock, no ordering constraints) + +The colonies server's workload (moderate write rate, point-lookup reads, no long-running +read transactions) doesn't benefit from MVCC. + +### Retention policy: batched deletes + +`ApplyRetentionPolicy` iterates all processes, attributes, logs, and process graphs, +deleting expired entries. Under an exclusive `db.mu.Lock()`, this would block all +writes for the entire duration -- unacceptable for a system that must not hang. + +**Solution: batch deletes with yield.** + +The retention method must NOT hold `db.mu` for the entire sweep. Instead: + +1. **Collect phase** (read lock): scan for expired IDs under `db.mu.RLock()`, + collect up to N candidate IDs per batch +2. **Delete phase** (write lock): acquire `db.mu.Lock()`, delete the batch, + release the lock +3. **Repeat** until no more expired entries + +```go +func (db *EmbeddedDatabase) ApplyRetentionPolicy(retentionPeriod int64) error { + const batchSize = 100 + cutoff := time.Now().Add(-time.Duration(retentionPeriod) * time.Second) + + for { + // Collect a batch of expired process IDs (read lock) + db.mu.RLock() + var batch []string + for _, p := range db.processes.All() { + if p.State == core.SUCCESS && p.SubmissionTime.Before(cutoff) { + batch = append(batch, p.ID) + if len(batch) >= batchSize { + break + } + } + } + db.mu.RUnlock() + + if len(batch) == 0 { + break + } + + // Delete the batch (write lock) + db.mu.Lock() + for _, id := range batch { + // re-check under write lock (may have been deleted by another goroutine) + if p, ok := db.processes.Get(id); ok { + if p.State == core.SUCCESS && p.SubmissionTime.Before(cutoff) { + db.removeProcessFromIndexes(p) + db.RemoveAllAttributesByTargetID(p.ID) + db.processes.Delete(p.ID) + } + } + } + db.mu.Unlock() + } + + // Same pattern for logs, process graphs, attributes... + return nil +} +``` + +This ensures: +- Each write lock is held for at most `batchSize` deletes (microseconds) +- Other writes (process assignment, metric updates) can proceed between batches +- The system never hangs, even with millions of expired entries +- Re-check under write lock handles races where entries are deleted between phases + +## Implementation Plan + +### Phase 1: Audit all write methods + +Scan all `*.go` files in the embedded package for multi-step write patterns: + +```go +// Pattern 1: read-modify-write (dangerous) +existing, ok := db.store.Get(key) +// ... modify ... +db.store.Put(key, modified) + +// Pattern 2: check-then-act (dangerous) +existing := db.store.Get(key) +if existing != nil { return error } +db.store.Put(key, new) + +// Pattern 3: iterate-delete (safe if single store, but holds lock a while) +for _, item := range db.store.All() { + db.store.Delete(item.ID) +} +``` + +Expected locations: +- `executors.go` -- AddExecutor (reactivate UNREGISTERED), RemoveExecutorByName +- `metrics.go` -- IncrementMetric +- `processes.go` -- Assign, Close, Fail, Cancel (state transitions) +- `processgraphs.go` -- state transitions +- `generators.go` -- increment counters +- `crons.go` -- update last run time +- `colonies.go` -- AddColony (duplicate name check) +- `users.go` -- AddUser (duplicate name check) + +### Phase 2: Add db.mu and convert write methods + +1. Add `mu sync.RWMutex` to `EmbeddedDatabase` struct +2. For each write method: + - Add `db.mu.Lock()` / `defer db.mu.Unlock()` at the top + - Keep using normal `db.store.Get()` / `db.store.Put()` (store locks stay) +3. Remove the targeted fixes: + - Remove `executorMu` from EmbeddedDatabase + - Revert `IncrementMetric` from `Lock()`/`*Unlocked()` pattern to normal + `Get()`/`Put()` under `db.mu` + +### Phase 3: Add db.mu.RLock to multi-store reads (if any) + +Review read methods that query multiple stores in a single call. If any exist and +need consistency, add `db.mu.RLock()`. Single-store reads (the vast majority) need +no changes -- the store's internal lock is sufficient. + +### Phase 4: Concurrency test suite + +The existing tests mostly run single-threaded. After adding `db.mu`, we need a +comprehensive concurrent test suite that exercises real contention patterns.

Create a temporary file in the same directory (`.tmp-*` prefix). +2. Write the JSON payload. +3. `fsync` the temporary file. +4. Rename it to the target path. + +If the process crashes at any point before the rename, the old file remains +intact. Temporary files left behind by crashes are filtered out during `Scan` and +`List`. + +### Scanning + +`Scan` iterates all `.json` files in sorted key order, deserializing each and +calling the provided callback. Used during startup (`LoadAll`) to populate the +in-memory store. + + +## Background Flusher + +The `Flusher` (`flusher/flusher.go`) is a background goroutine that periodically +writes dirty records from all stores to disk. + +### Type Signature + +```go +type Flusher struct { + stores []Flushable + interval time.Duration + stopCh chan struct{} + doneCh chan struct{} + mu sync.Mutex +} + +type Flushable interface { + FlushDirty() error +} +``` + +### Behavior + +- Default interval: **5 seconds** (configured in `Initialize()`). +- On each tick, the flusher calls `FlushDirty()` on every registered store. +- `FlushDirty()` snapshots the dirty and deleted sets under the store lock, then + performs disk I/O outside the lock. This minimizes lock contention with + concurrent readers and writers. +- On `Stop()`, a final flush is performed before the goroutine exits. +- After all stores are flushed, the WAL can be truncated (done during `Close()`). + +### FlushDirty Implementation + +```go +func (s *Store[K, V]) FlushDirty() error { + s.mu.Lock() + // snapshot dirty entries and deleted keys + // clear dirty/deleted sets + s.mu.Unlock() + + // write dirty entries to disk (outside lock) + // delete tombstoned records from disk (outside lock) +} +``` + +The snapshot-then-release pattern ensures that the store lock is not held during +potentially slow disk I/O. + + +## Indexing + +Indexes accelerate lookups that would otherwise require a full scan of the +in-memory store. They are **not persisted** -- they are rebuilt from data on every +startup. + +### MapIndex + +`MapIndex[K, SK]` (`index/mapindex.go`) maps a secondary key to a set of primary +keys. Used for equality lookups such as "all executors in colony X." + +```go +type MapIndex[K comparable, SK comparable] struct { + mu sync.RWMutex + index map[SK]map[K]struct{} +} +``` + +Methods: `Add(key, secondaryKey)`, `Remove(key, secondaryKey)`, +`Lookup(secondaryKey) []K`, `Count(secondaryKey) int`, `Clear()`. + +### CompoundIndex + +`CompoundIndex` (`index/compoundindex.go`) provides two-level nesting: +`group -> subgroup -> OrderedIndex`. Designed for queries like +`WHERE colony = $1 AND state = $2 ORDER BY priorityTime`. + +```go +type CompoundIndex struct { + mu sync.RWMutex + index map[string]map[int]*OrderedIndex[string] +} +``` + +The group key is a string (e.g. colony name), the subgroup key is an int +(e.g. process state), and each leaf is an `OrderedIndex` sorted by a numeric +sort key (e.g. priority time or submission time). + +Methods: `Add(group, subgroup, entry)`, `Remove(group, subgroup, entry)`, +`AscendFirst(group, subgroup, n, fn)`, `DescendFirst(group, subgroup, n, fn)`, +`Count(group, subgroup)`, `CountAll(group)`, `CountBySubgroup(subgroup)`. + +### OrderedIndex + +`OrderedIndex[K]` (`index/orderedindex.go`) wraps a B-tree +(`github.com/google/btree`) for sorted access. + +```go +type IndexEntry[K comparable] struct { + SortKey int64 + PrimaryKey K +} + +type OrderedIndex[K comparable] struct { + mu sync.RWMutex + tree *btree.BTreeG[IndexEntry[K]] + less func(a, b IndexEntry[K]) bool +} +``` + +Entries are sorted by `SortKey` ascending, with ties broken by primary key. +Supports ascending/descending iteration, range queries (`AscendRange`), and +threshold queries (`AscendGreaterThan`). + +### Index Rebuild + +`rebuildIndexes()` iterates every record in every store and populates all index +structures. This runs once during `Initialize()`, after both WAL replay and disk +load are complete. + + +## Concurrency Model + +The embedded database uses a two-level locking scheme. + +### Database-Level Lock (`db.mu`) + +```go +type EmbeddedDatabase struct { + mu sync.RWMutex // database-level transaction lock for write atomicity + // ... +} +``` + +Every write method acquires `db.mu` as a write lock to ensure atomicity across +multiple store and index updates. For example, `AddProcess` must update the +process store, the attribute store, and several indexes as a single atomic +operation. + +Read-only methods that touch multiple stores (e.g. `enrichProcess`, which reads +from both the process store and the attribute store) acquire `db.mu` as a read +lock for consistency. + +### Store-Level Lock (`store.mu`) + +Each `Store[K, V]` has its own `sync.RWMutex` that protects the `records`, +`dirty`, and `deleted` maps. This lock is also used by the background flusher: +`FlushDirty()` briefly holds the store lock to snapshot dirty entries, then +releases it before performing disk I/O. + +### Lock Ordering + +The invariant is: **`db.mu` must be acquired before any `store.mu`**. This +prevents deadlocks between database-level operations and the background flusher. + +### Avoiding Deadlocks from Nested Calls + +When a public method (e.g. `AddProcess`) already holds `db.mu`, it must not call +another public method that also acquires `db.mu`. Instead, it calls an internal +(unexported) helper. For example: + +- `AddProcess` holds `db.mu`, then calls `addAttributes` (not `AddAttribute`) + to add process attributes without re-acquiring the database lock. +- `DeleteColony` holds `db.mu`, then calls `removeUsersByColonyName` and similar + internal helpers for cascade deletes. + +### Retention Policy and Batched Deletes + +`ApplyRetentionPolicy` avoids holding locks for extended periods by processing +records in batches of 100: + +1. Acquire `db.mu.RLock()`, scan for up to 100 records matching the retention + criteria, collect their IDs. +2. Release the read lock. +3. Acquire `db.mu.Lock()`, delete the batch, release the write lock. +4. Repeat until no more records match. + +This allows concurrent readers to proceed between batches. + + +## Startup and Recovery Sequence + +`Initialize()` orchestrates the full startup sequence: + +``` +1. Create data directory os.MkdirAll(db.dataDir) +2. Open WAL wal.NewFileWAL(walPath, wal.SyncNone) +3. Create all stores (WAL=nil) db.createStores(nil) +4. Create all indexes db.createIndexes() +5.

Start background flusher db.flusher.Start() +``` + +Key details: + +- **Step 3**: Stores are created without a WAL reference. This ensures that + replayed entries (step 5) are not re-appended to the WAL. +- **Step 5**: `replayWAL` locks all stores, then calls `ReplayPut` / + `ReplayDelete` which modify memory directly without WAL writes. +- **Step 6**: `LoadAll` reads every JSON file from disk into memory. Records + already present from WAL replay are **not overwritten** -- the WAL version is + newer. +- **Step 7**: After replay and load are complete, the WAL is connected to all + stores so that future writes are logged. +- **Step 8**: Indexes are rebuilt from the final in-memory state, which + represents the union of disk data and WAL replay. + +### Shutdown + +`Close()` stops the flusher (which performs a final flush), truncates the WAL +(since all data is now on disk), and closes the WAL file. + +`Drop()` stops the flusher, closes the WAL, and removes the entire data +directory. + + +## Comparison with PostgreSQL Implementation + +Both backends implement `database.Database`: + +```go +type Database interface { + DatabaseCore + UserDatabase + ColonyDatabase + ExecutorDatabase + FunctionDatabase + ProcessDatabase + AttributeDatabase + ProcessGraphDatabase + GeneratorDatabase + CronDatabase + LogDatabase + FileDatabase + SnapshotDatabase + BlueprintDatabase + SecurityDatabase + LocationDatabase + MetricDatabase +} +``` + +| Aspect | Embedded | PostgreSQL | +|-----------------------|---------------------------------|------------------------------------| +| Dependencies | None | PostgreSQL + TimescaleDB | +| Read path | In-memory map lookup | SQL query over network | +| Write durability | WAL + async disk flush | PostgreSQL WAL + fsync | +| Concurrency | Go mutexes, single-process | MVCC, multi-process | +| Indexing | In-memory B-tree and hash maps | B-tree on disk (PostgreSQL) | +| Query capability | Programmatic filters | Full SQL | +| Scalability | Single node, memory-bound | Horizontal read replicas, sharding | +| Backup | Copy data directory | pg_dump, pg_basebackup, PITR | +| Time-series | Not supported | TimescaleDB hypertables | + + +## Limitations and Future Work + +- **No range queries on arbitrary fields.** Only the `OrderedIndex` (used for + process priority and graph submission time) supports ordered iteration.

With N executors of the same type but only 1 valid target, the round-robin lands on the right executor only ~1/N of the time. The wrong picks instantly fail Assign() (name mismatch) and re-poll. The correct executor sits in its 10s long-poll until either timeout or a future round-robin happens to land on it — observed as a 5-9s queue spike per routed tool call. Broadcasting wakes all candidates; only the named one wins the assign atomically; the rest no-op (cheap). Round-robin thundering-herd protection is preserved for unrouted processes (the bulk-throughput case). 2. controllers: replace the flat 500ms × 10 retry loop in Resolve with exponential backoff (1ms → 50ms cap, 50 retries, ~1s total budget). The retry handles same-server graph-mutation races (AddChild's row not yet visible when a concurrent Assign tries to Resolve) and multi- server propagation delays. The original 500ms sleep added 5s worst- case wall-clock per assignment under dynamic-graph load. Same correctness guarantee, ~50-100x lower typical latency. Plus diagnostic logging in HandleAssignProcess (per-call AssignDurMs, TryCount, WaitEventCount, WaitFromSubMs) and resolveWithBackoff (retry count + duration) to make this whole subsystem observable. Without these the 5-9s spikes were impossible to attribute. --- pkg/backends/gin/eventhandler.go | 38 +++++- pkg/server/controllers/colonies_controller.go | 119 +++++++++++------- pkg/server/handlers/process/handlers.go | 26 ++++ 3 files changed, 133 insertions(+), 50 deletions(-) diff --git a/pkg/backends/gin/eventhandler.go b/pkg/backends/gin/eventhandler.go index afa3b8ec8..8039af04e 100644 --- a/pkg/backends/gin/eventhandler.go +++ b/pkg/backends/gin/eventhandler.go @@ -235,6 +235,23 @@ func (handler *DefaultEventHandler) sendSignal(process *core.Process) { } } + // Routed processes (those with Conditions.ExecutorNames) can only run + // on a specific named executor.

Adds the foundational types with full unit-test coverage; no server- or client-side wiring yet. pkg/rpc/subscribe_files_msg.go: - SubscribeFilesPayloadType constant ("subscribefilesmsg") - SubscribeFilesMsg with ColonyName, LabelPrefix, Kinds, Timeout, MsgType. Constructor, ToJSON / ToJSONIndent, Equals (including element-wise Kinds compare), CreateFromJSON. - Tests cover round-trip, indented round-trip, Equals across each field as the discriminator, MsgType drift, identical-Kinds-with- different-backing-arrays, empty/nil Kinds sentinel, payload-type pinning, and JSON tag shape. pkg/core/file_event.go: - FileEventKind iota: FileAdded(1), FileUpdated(2), FileRemoved(3). Wire-stable integers; do not renumber. - FileEvent type with Kind, ColonyName, Label, Name, FileID, Size, Checksum, ChecksumAlg, Timestamp. JSON-marshalled with omitempty on the file-identifying fields so FileRemoved events don't carry a misleading FileID="" or Size=0. - MatchesPrefix and MatchesKinds — the matchers the server will use on the fan-out path. Prefix uses a path-shaped rule (exact match OR HasPrefix(prefix + "/")), so /home/root/inbox/2026 matches a subscription on /home/root/inbox but /home/root/in does not match /home/root/inbox. - Constructors CreateFileAddedEvent / CreateFileUpdatedEvent / CreateFileRemovedEvent (the last takes coordinates rather than a *File pointer because the file is already gone by the time the caller invokes it). - Tests cover wire-stable enum values, string formatting, JSON round-trip, omitempty behaviour for FileRemoved, the matcher edge cases (empty prefix, exact, descendant-with-separator, sibling, non-separator-prefix, kind filter with garbage values), every constructor, Equals including timestamp non-equality, and JSON tag shape. Phase 2 will add the server-side subscription registry and the publish hooks in pkg/server/handlers/file/. Phase 3 the client API plus end-to-end integration tests. --- pkg/core/file_event.go | 173 +++++++++++++++++++++++ pkg/core/file_event_test.go | 209 ++++++++++++++++++++++++++++ pkg/rpc/subscribe_files_msg.go | 89 ++++++++++++ pkg/rpc/subscribe_files_msg_test.go | 114 +++++++++++++++ 4 files changed, 585 insertions(+) create mode 100644 pkg/core/file_event.go create mode 100644 pkg/core/file_event_test.go create mode 100644 pkg/rpc/subscribe_files_msg.go create mode 100644 pkg/rpc/subscribe_files_msg_test.go diff --git a/pkg/core/file_event.go b/pkg/core/file_event.go new file mode 100644 index 000000000..031582d36 --- /dev/null +++ b/pkg/core/file_event.go @@ -0,0 +1,173 @@ +package core + +import ( + "encoding/json" + "strings" + "time" +) + +// FileEventKind discriminates the three observable transitions on a +// ColonyFS file.

Pure logic, no websocket coupling — that lands in the next commit. pkg/backends/file_event_bus.go: - FileEventBus interface: Publish, Subscribe, NumberOfSubscribers, Stop. Single-server scope; no cross-server replication (matches the process-subscription model already in this repo). - inMemoryFileEventBus default implementation. Per-subscriber buffered channel (DefaultEventBufferSize=256). Drop-oldest on overflow with ErrSubscriberOverflowed delivered exactly once per overflow streak on a separate error channel; re-armed automatically once the subscriber drains. - Filtering: same colony, MatchesPrefix on the label, MatchesKinds on the event kind. Kinds slice is defensively copied at subscribe time so caller-side mutation doesn't drift the live filter. - Lifecycle: ctx cancel removes the subscription and closes both channels; Stop drains every active subscriber and turns Publish into a no-op. Idempotent. - Concurrency: bus.mu (RWMutex) held through the whole Publish fan-out, so removeSubscriber waits for in-flight sends to finish before closing the subscriber's channels. Sends are non-blocking per subscriber, so a slow subscriber can't stall fast ones. pkg/backends/file_event_bus_test.go (15 tests, all -race-clean): - Happy-path delivery; matchers (colony / label-prefix / kind) each verified independently with both positive and negative cases. - Empty-prefix wildcard semantics with explicit cross-colony isolation guard. - Multi-subscriber fan-out where filters differ. - Context-cancel cleanup (channels close, NumberOfSubscribers drops back to zero). - Stop idempotency, post-Stop Publish/Subscribe behaviour. - Backpressure: 50-event burst into a 2-slot buffer triggers overflow signal and bounds the delivered count to <= buffer+1. - Buffer-size clamping for non-positive args. - Nil-event tolerance. - Per-colony NumberOfSubscribers counts. - TestConcurrentPublishAndSubscribe: 4 publisher goroutines x 200 events x 8 subscriber goroutines x 50 subscribe/cancel cycles. Catches the close-then-send race that the per-fan-out lock fixes. - Defensive-copy guard for the kinds slice. Phase 2b will hook this bus into the file handlers (publish on HandleAddFile / HandleRemoveFile success). Phase 2c wires the websocket subscription dispatch. --- pkg/backends/file_event_bus.go | 269 +++++++++++++++++++ pkg/backends/file_event_bus_test.go | 389 ++++++++++++++++++++++++++++ 2 files changed, 658 insertions(+) create mode 100644 pkg/backends/file_event_bus.go create mode 100644 pkg/backends/file_event_bus_test.go diff --git a/pkg/backends/file_event_bus.go b/pkg/backends/file_event_bus.go new file mode 100644 index 000000000..8f3b9085e --- /dev/null +++ b/pkg/backends/file_event_bus.go @@ -0,0 +1,269 @@ +package backends + +import ( + "context" + "errors" + "sync" + "time" + + "github.com/colonyos/colonies/pkg/core" +) + +// ErrSubscriberOverflowed is sent on a subscriber's error channel when its +// buffered event channel filled up and at least one event was dropped. +// Subscribers can use this as a signal to resync via GetFileData rather +// than relying on real-time delivery alone. +var ErrSubscriberOverflowed = errors.New("file subscriber overflowed; events dropped") + +// FileEventBus is the in-process publish/subscribe primitive for ColonyFS +// file events.

The handler publishes after the underlying DB call succeeds. The bus is optional (nil-tolerant) so deployments / tests that haven't enabled realtime keep working unchanged. Discrimination between FileAdded and FileUpdated: we look up GetLatestFileByName(colony, label, name) BEFORE the AddFile call. If a prior revision exists, this is an update; otherwise a new file. A transient lookup error degrades to FileAdded rather than blocking the write — strictly best-effort signalling. HandleRemoveFile by-ID resolves the file's label+name BEFORE deleting so the published FileRemoved event carries the right coordinates; RemoveFile by-name uses the kwargs directly. Either way, FileRemoved omits FileID/Size/Checksum (they're misleading after the delete) via omitempty on the FileEvent struct. Plumbing: - file.Server interface gains FileEventBus() backends.FileEventBus. - ServerAdapter delegates to *Server.FileEventBus(). - *Server gets fileEventBus field + FileEventBus() / SetFileEventBus / EnableFileEventBus accessors. Lazy: zero overhead when nobody has subscribed. Tests (handlers_pubsub_test.go, 9 cases, all -race-clean): - HandleAddFile publishes FileAdded with full metadata for first revisions. - HandleAddFile publishes FileUpdated for new revisions of an existing (colony, label, name). - HandleRemoveFile (by name) publishes FileRemoved with right coordinates and no file-id/checksum. - HandleRemoveFile (by id) does the lookup-before-delete so the event still has label+name even though the caller only had the id. - Nil bus is a clean no-op for both handlers. - Cross-colony isolation: events for colony A don't leak to a colony-B subscriber. - Label-prefix scoping survives end-to-end through the handler: /home/root/inbox subscriber sees /home/root/inbox/2026 events but not sibling /home/root/outbox events. - Failed AddFile (membership rejected) does NOT publish — events only fire after the DB write succeeds. Phase 2c (next commit) wires the websocket subscription dispatch: new SubscribeFiles payload routing in pkg/backends/gin/realtime.go, file subscription adapter in pkg/backends/gin/, end-to-end test that opens a websocket, subscribes, writes a file, observes the event. --- pkg/server/handlers/file/handlers.go | 47 +++ .../handlers/file/handlers_pubsub_test.go | 273 ++++++++++++++++++ .../handlers/file/handlers_unit_test.go | 5 + pkg/server/server.go | 32 ++ pkg/server/server_adapter.go | 7 + 5 files changed, 364 insertions(+) create mode 100644 pkg/server/handlers/file/handlers_pubsub_test.go diff --git a/pkg/server/handlers/file/handlers.go b/pkg/server/handlers/file/handlers.go index a97751a55..a3c51e70a 100644 --- a/pkg/server/handlers/file/handlers.go +++ b/pkg/server/handlers/file/handlers.go @@ -3,6 +3,7 @@ package file import ( "errors" "net/http" + "time" "github.com/colonyos/colonies/pkg/backends" "github.com/colonyos/colonies/pkg/core" @@ -19,6 +20,11 @@ type Server interface { SendEmptyHTTPReply(c backends.Context, payloadType string) Validator() security.Validator FileDB() database.FileDatabase + // FileEventBus is the realtime publish/subscribe primitive used by + // SubscribeFiles.

Bypasses the colonies-controller command queue (mirrors the ChannelRouter approach in handleSubscribeChannel) so a slow file-event subscriber never serialises unrelated colony work. - Overflow signals (ErrSubscriberOverflowed) are surfaced to the client as informational error messages but the subscription stays open so the client can resync via GetFileData. - Timeout 0 maps to a 24h server-side cap so a forgotten subscriber doesn't pin resources forever. pkg/client/subscription.go: - New FileSubscription type with EventChan, ErrChan, conn, Close(). pkg/client/realtime_client.go: - New SubscribeFiles(colonyName, labelPrefix, kinds, timeout, prvKey) method, mirroring SubscribeProcesses. Builds the RPC msg, opens the realtime websocket, and runs a read goroutine that decodes FileEvents into EventChan and surfaces errors on ErrChan. pkg/server/handlers/realtime/file_handler_test.go (7 E2E tests): - DeliversAddedEvent: full path subscribe -> AddFile -> client receives FileAdded with correct (colony, label, name, fileid, size, checksum). - DeliversUpdatedEvent: second revision of same name produces FileUpdated, not a duplicate FileAdded. - KindFilter: subscribing to FileAdded only suppresses subsequent FileRemoved events. - LabelPrefixScoping: /inbox subscriber sees /inbox/2026 events but not /outbox events. - CrossColonyIsolation: colony-2 subscriber doesn't see colony-1 events. - RejectsForeignColony: subscribing with a key that doesn't own colony membership is rejected (either at handshake or via ErrChan). - MultipleSubscribers: wide and narrow filters in the same colony both receive the events that match each filter. All tests run against the real Colonies server stack (etcd, Postgres, gin websocket, full RPC pipeline) and pass. The feature is now end-to-end functional: clients can SubscribeFiles to a label prefix, write files via AddFile (or have any other client write them), and observe FileAdded / FileUpdated / FileRemoved events in real time over a websocket. --- pkg/backends/gin/realtime.go | 109 +++++++ pkg/client/realtime_client.go | 78 ++++- pkg/client/subscription.go | 23 ++ .../handlers/realtime/file_handler_test.go | 274 ++++++++++++++++++ 4 files changed, 483 insertions(+), 1 deletion(-) create mode 100644 pkg/server/handlers/realtime/file_handler_test.go diff --git a/pkg/backends/gin/realtime.go b/pkg/backends/gin/realtime.go index cead5e3ba..da543c28d 100644 --- a/pkg/backends/gin/realtime.go +++ b/pkg/backends/gin/realtime.go @@ -1,6 +1,7 @@ package gin import ( + "context" "encoding/json" "errors" "fmt" @@ -26,6 +27,12 @@ type RealtimeServer interface { ChannelRouter() *channel.Router ProcessDB() database.ProcessDatabase Validator() security.Validator + // FileEventBus is the realtime bus consumed by SubscribeFiles.
