🐛 Keep file_change revisions on their own deletion schedule (#12419)
* 🐛 Keep file_change revisions on their own deletion schedule Restoring a file from the trash cleared the deletion mark on every file_change row of that file, revisions included. A revision is born already scheduled for deletion one hour later, and objects-gc only looks at rows that carry a date, so unmarking one left it in the table for ever: production had 358,517 of them across 3,614 files. The file deletion cascade had the mirror problem: it rewrote the date of rows that already had one, pushing a revision out to the trash lifetime. Restrict the restore to durable history and date only the rows that have no date yet, so a revision keeps the schedule it was born with. A pinning test covers the snapshot update path, which cannot reach a revision because it resolves its row through a read filter. The backend memories now carry the model of the three file_data classes and this invariant, in place of the two superseded stubs. Closes #12418 AI-assisted-by: deepseek-v4.1-flash * 📚 Add autovacuum and Postgres exporter notes to Grafana memory Record what this Grafana instance can and cannot show about autovacuum so the next session does not have to re-derive it: - The Postgres exporter scrapes the primary as well as the read-only replica, so the primary's pg_stat_activity and pg_settings_* are in Prometheus even though the SQL datasource cannot reach them. - It publishes no pg_stat_progress_* collector, and pg_stat_activity_count has no backend_type label: autovacuum workers are the usename/application_name-less bucket with state=active. The launcher shows up as the AutoVacuumMain wait event, and it is absent on the replica. - A metric the exporter does not publish needs a custom query block in its YAML queries file and a restart of the exporter. - The Postgres server ships its own log to Loki (the job is postgresql, primary only), whose streams carry only filename, instance, job and level. The completed vacuum lines live there: a per-table history, not a view of what runs now. - The PostgreSQL section now ends with the vacuum panels, with the Vacuum TXID age table last; an in-flight per-table view would need a pg_stat_progress_vacuum collector in the exporter itself.

# Backend HTTP, Storage, Media, and File Data Subtleties
|
||||
|
||||
## Config and HTTP/session middleware
|
||||
|
||||
- `app.config/config` and `flags` are dynamic `defonce` vars populated from `PENPOT_*` env vars through the shared schema string transformer. Tests and tooling can bind them.
|
||||
- `parse-flags` automatically adds `:disable-secure-session-cookies` when `public-uri` is plain HTTP and not localhost. This changes cookie defaults without an explicit env flag.
|
||||
- The backend sets Clojure `*assert*` globally from the `:backend-asserts` feature flag. Assertion-dependent checks can therefore differ by runtime flags.
|
||||
- Request body parsing is mostly POST-oriented and supports Transit JSON plus plain JSON. Plain JSON request keys are kebab-decoded before being merged into `:params`.
|
||||
- Response formatting negotiates with `Accept` or `_fmt=json`. Transit is the default for collection/boolean bodies; JSON encoding has special pointer-map handling.
|
||||
- Auth prefers the session cookie token before the `Authorization` header. Headers may be `Token` or `Bearer`; JWTs with `kid=1` and `ver=1` are decoded as v1 session tokens, otherwise they are treated as legacy tokens.
|
||||
- Shared-key auth requires `x-shared-key` as `<key-id> <key>` and stores the lowercased key id on the request. If no shared keys are configured it always rejects.
|
||||
- Session management uses DB storage unless the DB pool is read-only, then falls back to the in-memory manager. DB sessions support both legacy string ids and v2 UUID session ids.
|
||||
- Session cookies are renewed when using a legacy string id or when `modified-at` is older than the renewal interval. SameSite is `none` for CORS, otherwise strict/lax based on config.
|
||||
|
||||
## Storage and media
|
||||
|
||||
- Storage abstraction, backend configuration, logical buckets, object lifecycle, deduplication, access rules, and garbage collection: `mem:backend/storage`.
|
||||
- SVG validation strips DOCTYPE and uses secure SAX parsing. Basic SVG info falls back to 100x100 dimensions when width/height/viewBox are missing.
|
||||
- Raster metadata is shell-derived with ImageMagick `identify`, verifies detected MIME against the supplied MIME, and swaps dimensions for EXIF orientations 6/8.
|
||||
- Remote image download requires 2xx status, `content-length`, a known MIME, and size under the configured maximum before writing the temp file; mismatched byte count is an internal error.
|
||||
- Font processing shells out to FontForge and WOFF conversion tools and can derive TTF/OTF/WOFF variants from uploaded fonts.
|
||||
|
||||
## File data persistence
|
||||
|
||||
- File data backends are `legacy-db`, `db`, and `storage`. The storage backend keeps encoded file data in storage bucket `file-data`; the DB row stores metadata with `storage-ref-id` and nil data.
|
||||
- `fdata/upsert!` touches any storage object referenced by incoming metadata before storing the new row/blob.
|
||||
- Pointer-map fragments are persisted separately as type `fragment`, and only modified pointer maps are written.
|
||||
- File snapshots (versions) keep their metadata row in `file_change` and their payload in `file_data` (`type = 'snapshot'`). With the `db` backend `file_change.data` stays NULL: that column is only written by the `legacy-db` backend, plus the rows written before the 2025-07 file storage refactor.
|
||||
- Tell a snapshot apart by `label IS NOT NULL` (with `created_by` / `deleted_at` as needed), never by `file_change.data IS NOT NULL`: the label holds with every file data backend, and the payload column stopped meaning "this is a snapshot" when the payload moved out. Queries that identify versions must use the label.
|
||||
- The version quota counts of `app.rpc.quotes` (`sql:get-snapshots-per-file`, `sql:get-snapshots-per-team`) are served by the partial index `file_change__user_snapshots__idx`, whose predicate mirrors their where clause; changing one without the other drops the index only scan and the count walks the whole table again.
|
||||
- `fdata/realize` combines pointer realization and object-map realization. Use it before operations that need complete in-memory file data instead of pointer placeholders.

- A `file_data` row is one of three classes, told apart by `type`: `main` is the file's current state and carries `id = file_id`; `snapshot` is a point-in-time copy whose `id` is the one its `file_change` row shares; `fragment` is a piece of the pointer-map, referenced from the file's data.
|
||||
- Their lifecycles differ: `main` and `snapshot` live with the file (dated when it is deleted, undated when it is restored), while a `fragment` carries no date and is collected by `file_gc` once the file stops referencing it. Neither is a session buffer, so do not read a `fragment` as an ephemeral revision.

|

- Revisions live only in `file_change` and have no `file_data` counterpart. They are born already scheduled for deletion one hour later (`app.rpc.commands.files-update`) and the snapshot paths cannot reach one, because they resolve their row through a `label IS NOT NULL` filter.
|
||||
- A deletion date is assigned once and never moved: `restore-files` (`app.rpc.commands.files`) unmarks only durable history, the `:file` method of `app.tasks.delete-object` dates only rows that have no date yet, and `objects-gc` collects only rows that carry one. Unmarking a revision leaves it invisible to `objects-gc` for ever, because nothing sets that date again.

## Datasources
|
||||
|
||||
- Metrics — **Prometheus**, uid `xkRmyFBGk`. PromQL. Metric families: `penpot_*` (RPC, task timings, CLIMIT, HTTP, websocket, storage, and the application log events of the backend), `hikaricp_*`, `jvm_*` and `process_*` on the backend (`job="app"`); `pg_*` from the Postgres exporter (`job="postgres"`); `redis_*` from the Redis exporter (`job="redis"`); `node_*` and `container_*` from node-exporter and cAdvisor. Backend histograms are in **milliseconds**. Tails (ms): requests and waits to 60000, background tasks to 300000, Redis eval to 10000; the sub-7500 buckets are identical everywhere, so old quantiles stay comparable.
|
||||
- The Postgres exporter scrapes **the primary as well as the read-only replica**, so the primary's `pg_stat_activity`, `pg_settings_*` and `pg_stat_bgwriter_*` are in Prometheus even though the SQL datasource cannot reach them (the replica's views describe the replica, not the primary).
|
||||
- Per-database data from the exporter is **aggregate only**: `pg_settings_*` (the whole server configuration, so autovacuum, checkpoint and memory parameters are readable from Prometheus), `pg_stat_database_*`, `pg_stat_bgwriter_*`, `pg_stat_activity_*`, and replication/lock counts. It publishes **no per-table series** (`pg_stat_user_tables_*` resolves empty), so dead tuples, per-table reloptions and relation sizes are SQL-only questions.
|
||||
- It publishes **no `pg_stat_progress_*` collector** and `pg_stat_activity_count` carries no `backend_type` label, so a session is only identifiable by its remaining labels: autovacuum workers are the bucket with `usename` and `application_name` empty plus `state="active"`, and `pg_wait_events_connections{wait_event="AutoVacuumMain"}` is the autovacuum launcher alive (absent on the replica).
|
||||
- A metric the exporter does not publish itself has to be added as a custom query block in its YAML queries file on the exporter host (that is where `pg_wait_events_connections` comes from), and in this build the file is read at startup: restart the exporter after editing. There is no per-metric flag to turn on.
|
||||
- Logs — **Loki**, uid `h3CGKhEMk`. LogQL, and filter by the structured metadata `logger`/`level` (`{job="penpot"} | logger="..." | level="ERROR"`). Two things to remember when counting from it: the CLIMIT rejections have their own counters (`penpot_rpc_climit_rejected_total`, by `name` and `reason`) and their `hint="rejected"` line goes out at WARN only when something is left queued behind the call (a lone caller that times out is written at TRACE), so counting lines is not counting rejections -- the same goes for `hint="enqueued"` and `hint="acquired"`; and the only signal that exists nowhere else is the profile behind a queue (`logger="app.rpc.climit"`, whose `id` carries the key), chased there on demand.
|
||||
- SQL — **Postgres**, uid `y8ea9tfMk`. Panels need `rawQuery: true`, `editorMode: "code"` and `format: "table"`. The `task` table is the only truth about the queue depth. It is a **read-only replica**: it rejects any write, `CREATE TEMP TABLE` included, so queries through it must be plain `SELECT`s. It also cuts long-running queries (the MCP path has a short timeout), so bound them (e.g. a list of ids); an empty answer there is not proof that there is no data.
|
||||
- The Postgres server also ships its own log (`job="postgresql"`, primary only). Those streams carry just `filename`, `instance`, `job` and `level` — no `environment`/`hostname` — so selectors need `instance=~"$host.$env.*"`. `log_autovacuum_min_duration` is low enough that every autovacuum leaves an `automatic vacuum of table "db.schema.table"` line with pages, tuples, index scans and `elapsed`: a per-table history of **finished** vacuums (retrospective, not a view of what runs now). A day of vacuums is only a couple of hundred lines, so pulling them raw over `query_range` and parsing the table, the pages scanned, `tuples: N removed` and the `removable cutoff` XID age in the client works well — less fighting than making LogQL's `pattern`/`regexp` chew a multi-line message.

It is a **read-only replica**: it rejects any write, `CREATE TEMP TABLE` included, so queries through it must be plain `SELECT`s. Catalog data (`pg_class`, `pg_partition_tree`, `pg_stats`, and `reloptions`) describes the primary faithfully, because catalogs replicate; the statistics views (`pg_stat_user_tables`, `pg_stat_all_tables`) read as zero there, since statistics are per-instance and are not replicated. It also cuts long-running queries (the MCP path has a short timeout), so bound them (e.g. a list of ids); an empty answer there is not proof that there is no data.

- The PostgreSQL section ends with a block of vacuum panels: two stats (autovacuum workers active on the primary, and the launcher alive), a Loki timeseries of finished vacuums per interval and table, and then the `Vacuum TXID age` table, which is the last panel of the section. The worker stat is an approximation — it counts the `pg_stat_activity` bucket described above, because the exporter publishes no `backend_type` — and the Loki panel is retrospective by construction. A per-table, in-flight view (table, phase, progress) needs a `pg_stat_progress_vacuum` collector added to the exporter itself.
