Migration cleanup + file-lifecycle and sync fixes - #240
Merged
Conversation
Every down.sql now follows one format: a two-line header (`-- Revert <name>.` + the reverse-order note), flat `DROP ... IF EXISTS` statements grouped by object-type tier with a blank line between tiers, in reverse dependency order. Functions are dropped by name (none are overloaded); inline notes appear only where the order is non-obvious. This also fixes two real reversion bugs: - The chat down.sql could not run: chat_messages and chat_sessions reference each other, so neither table could be dropped first. CASCADE on the first clears the cross constraint. - The initial down.sql missed two functions (setup_updated_at_no_soft_delete, trigger_updated_at_no_soft_delete), leaving them orphaned on revert. Verified by reverting the full chain (every down.sql, in order) to an empty schema with zero orphaned tables, types, views, functions, or extensions, then re-applying cleanly.

Bring every up.sql to one house style, using the chat migration as the reference: a prose feature/scope header, descriptive (not imperative) section comments, each column's CHECK immediately after its column with chronological and cross-column checks grouped at the table end, one descriptive comment per index, and a full COMMENT ON TABLE + per-column COMMENT ON block for every table. Redundant inline comments that merely restated the next statement inside function bodies are dropped. Also corrects stale/incorrect documentation surfaced while reformatting: - accounts: session_type comment listed non-existent token kinds (web, mobile, api, desktop) — the enum is web/api/cli; password_hash said bcrypt — it is Argon2. - notifications: header and table comment described mention/reply events that the NOTIFICATION_EVENT enum does not have. - connections / pipelines: several column comments said "(optional)" on NOT NULL columns; provider vs provider_type were conflated. - pipelines: header/table/definition comments referenced "artifacts" and "steps/schemas" that no column holds. - workspaces: table comment claimed quota/security-control columns that do not exist; the slug column had no comment. Verified semantics are unchanged: schema.rs is byte-identical, a full pg_dump DDL diff shows only comment removals inside function bodies (zero table, column, constraint, type, or index changes), and the whole chain reverts to an empty schema and re-applies cleanly.

Remove 5 views and 7 functions that no code path reaches — none are declared in
schema.rs, mapped to a model, or queried; the cleanup logic they duplicated
lives in the Rust query layer (e.g. cleanup_expired_account_api_tokens).
Views (all app-unreachable; only manual psql could hit them):
active_user_sessions, pending_workspace_invites, workspace_member_summary,
active_workspace_pipeline_runs, workspace_pipeline_run_history
Functions:
soft_delete_record, restore_record, cleanup_expired_records — generic
dynamic-SQL helpers; Diesel does these type-safely instead
cleanup_expired_auth_data, cleanup_expired_invites,
cleanup_expired_notifications — per-table cleanup, done in Rust
find_duplicate_workspace_files — no dedup feature consumes it
Kept: the trigger machinery (trigger_updated_at*, setup_updated_at*),
set_workspace_file_version_number, generate_secure_token, is_valid_email —
all have live callers.
Verified: schema.rs byte-identical (views/functions never appeared in it), the
full chain reverts to an empty schema and re-applies cleanly, and clippy passes.

A manual file delete only soft-deleted the row — it never purged the backing NATS object, and nothing reconciled the orphan (the retention worker only swept expires_at < now). Route manual delete through a shared RunBlobStore::purge_file so it reclaims storage exactly as expiry does. Make object reclamation durable with an explicit purge state: - workspace_files gains purged_at (stamped once the object is gone) with a purged-after-deleted CHECK and a partial index over pending purges. - purge_file's object delete is best-effort; on failure purged_at stays NULL so the reaper retries — a transient object-store outage self-heals. - Rename FileRetentionWorker -> FileReaper: it now runs an expiry sweep and a reconcile sweep (soft-deleted files whose object was never reclaimed), both ending in purge_file. Model pipeline runs as append-only audit history: - A run keeps its input/audit/output file references even after those files are deleted; a reader resolves a reference to a soft-deleted file as "gone", distinct from a NULL reference that means the run never had one (load_analyzed_document now returns 404 "analysis deleted" vs 409 "no analysis yet", not a generic 500). - Drop the trigger that nulled run references on file soft-delete — it corrupted history by conflating "deleted" with "never existed". Runs are never mutated by a file deletion. - input_file_id stays NOT NULL + ON DELETE CASCADE: the app never hard-deletes an individual file (soft-delete only), and the one hard delete — a whole-workspace teardown — correctly cascades files and runs away together. Fix a latent trigger/constraint contradiction surfaced by purged_at: once a row is soft-deleted, trigger_updated_at now freezes updated_at at deleted_at, so a post-deletion system stamp (marking an object purged) can't push updated_at past deleted_at and violate the deleted-after-updated CHECK. This is correct for any soft-deletable table, not just files. Add docs/design/workspace-stats.md sketching the tiered stats design. Verified: workspace teardown still cascades cleanly; soft-delete keeps runs and their references; purge marks purged_at without tripping the timestamp CHECK; the full chain reverts and re-applies; full gate green.

workspace_pipelines carried schedule_cron, schedule_tz, and next_run_at, but nothing populated or read them: the create path always wrote None, no scheduler acted on them, and they were never exposed in a request or response DTO. (The live scheduling feature is on connections, via workspace_connection_schedule and the sync worker.) Drop the three columns and their CHECK constraints from the pipelines migration, the fields from all three model structs and the is_scheduled() helper, and the now-dead schedule constraint variants and their error arms.

The scheduled-sync worker listed candidate connections, then per connection re-read its schedule row (for the cron) and its latest sync — 1 + 2N queries per tick. list_scheduled_connections now returns each connection with its cron (the query already joins the schedule; the IS NOT NULL filter lets the column be selected non-null), and find_latest_workspace_connection_syncs batch-loads the latest sync per connection via DISTINCT ON. The worker snapshots both in two queries and computes due-ness from the in-memory map.

Inline comments:
In `@crates/nvisy-postgres/src/query/workspace_connection_sync.rs`:
- Around line 423-440: Update find_latest_workspace_connection_syncs so its
DISTINCT ON ordering adds dsl::id.desc() after dsl::started_at.desc(), ensuring
deterministic selection when timestamps tie while preserving the existing
connection_id grouping and newest-started-at behavior.
In `@crates/nvisy-server/src/handler/files.rs`:
- Around line 605-609: Update the delete endpoint description to state that
deletion removes the file content and the backing object, matching the purge
behavior in purge_file; remove or revise any claim that deleted files can be
recovered during retention.
In `@crates/nvisy-server/src/service/run_blob_store.rs`:
- Around line 75-84: Update RunBlobStore::purge_file so delete failures return a
distinct pending/failed outcome and mark purged_at only after confirmed removal;
at crates/nvisy-server/src/service/run_blob_store.rs lines 75-84, return that
failure outcome from the deletion-error branch, while lines 89-118 must treat
invalid keys and unknown buckets as failed cleanup rather than successful
deletion. Update FileReaper::sweep at
crates/nvisy-server/src/service/file_reaper.rs lines 103-115 to increment purged
only when the shared purge operation confirms that purged_at was stamped.
In `@docs/design/workspace-stats.md`:
- Around line 45-47: Update the by_kind contract in the workspace statistics
documentation to include the artifact file_kind alongside original, redacted,
and audit, ensuring artifact rows are represented consistently with file_count
and total_bytes.
- Line 3: Update the workspace-stats status header and the related status
section to consistently identify Tier 1 as implemented in this PR, Tiers 2–3 as
planned follow-up, and retain the explicit upstream elide dependency for Tier 3.
- Around line 171-180: Update the run usage persistence and read-time
aggregation described near analyzed.usage so historical cost metrics remain
stable: persist the applied model pricing/version or the computed run cost with
each run, then use that persisted basis when reporting spend and cost over time.
If pricing remains configuration-derived, explicitly label the result as a
current-rate estimate instead of historical cost.
- Around line 49-54: Update the “Storage semantics — live logical bytes” section
to explicitly identify total_bytes as logical usage, and document that
soft-deleted rows with purged_at unset remain in NATS while excluded by
deleted_at IS NULL, causing temporary divergence from physical storage until
cleanup succeeds.
- Around line 56-73: Update the purge section to reference the current
FileReaper worker instead of the obsolete FileRetentionWorker/file_retention
terminology, and replace the claim that manual purge is an unfixed leak with an
accurate description of the implemented purged_at reconciliation path.
- Around line 41-45: Update the workspace stats design around total_bytes,
file_count, by_kind, and error_rate to define the empty-result response,
including COALESCE handling for aggregate NULLs, the empty grouped-row
representation, and NULLIF-based zero-denominator behavior for error_rate;
document the resulting response field nullability.
In `@migrations/2025-05-21-121131_accounts/up.sql`:
- Around line 1-2: Update the migration headers to describe only database
objects actually created: in migrations/2025-05-21-121131_accounts/up.sql lines
1-2 remove the active-session view reference; in
migrations/2025-05-21-121115_initial/up.sql lines 1-3 remove the restore-helper
reference; and in migrations/2025-05-21-222840_workspaces/up.sql lines 1-4
remove references to summary views, pending views, and the expiry-cleanup
function.
In `@migrations/2026-01-19-045013_connections/up.sql`:
- Around line 186-188: Update the documentation comment describing records
processed by a sync so it does not imply that every sync imports objects; scope
the incremental “only objects not already imported” statement to import-mode
syncs, or explicitly document the behavior of both import and export modes.
Preserve the existing schema and migration logic.
In `@migrations/2026-01-19-045014_pipelines/up.sql`:
- Around line 56-122: Add a follow-up migration for databases already at version
20260119045014: in up.sql remove the obsolete scheduling columns and constraints
from workspace_pipelines and drop the pipeline views, while down.sql restores
them exactly. Validate with a normal forward upgrade from that recorded version,
not only a revert-and-reapply on a fresh database.
Apply the same fix in `@docs/design/workspace-stats.md` around lines 118 - 120:
The design note identifies the same risk for schema objects added or changed in
the historical migration.
In `@migrations/2026-08-19-034709_chat/down.sql`:
- Around line 4-7: Update the migration rollback to drop chat_messages and
chat_sessions together in a single DROP TABLE statement without CASCADE,
preserving IF EXISTS so the rollback fails when unexpected external dependents
remain.

PostgreSQL documentation aggregate functions return null when no rows percentile_cont null empty input
💡 Result:
In PostgreSQL, aggregate functions (with the exception of count) return a null value when no rows are selected [1][2][3]. This behavior follows the SQL standard, which specifies that the result of any aggregate function other than count is null when no row qualifies [4]. Specifically regarding percentile_cont: 1. Empty Input: If the input set for percentile_cont is empty (i.e., no rows qualify), the function returns null [1][2]. 2. Null Fraction Argument: If the fraction argument passed to percentile_cont is null, the function will also produce a null result [5][6][7]. 3. Null Values in Input: All ordered-set aggregate functions, including percentile_cont, ignore null values in their aggregated input [5][6][7]. If you need to handle these cases—for example, to return a default value instead of null—you can use the coalesce function to substitute a specific value, such as 0 or an empty array, when the result is null [1][2][3].

Define empty-result and zero-denominator behavior.
Before implementing GET /workspaces/{ws}/stats, specify the response for no matching rows. SUM, AVG, and percentile_cont return NULL; COUNT(*) returns 0; and by_kind produces no grouped rows. Define whether error_rate is NULL or 0 when completed + failed = 0, and document the corresponding COALESCE/NULLIF expressions and response nullability.

Persist the pricing basis for historical cost metrics.
Deriving cost from the current server configuration causes past cost values to change when prices change. If the endpoint reports historical spend or cost over time, persist the applied price/version or computed cost with each run. Otherwise label the result as a current-rate estimate.

Add a forward migration for already-installed databases.
These edits change an already-versioned migration, so databases that recorded version 20260119045014 will skip the cleanup and retain the removed scheduling columns, constraints, views, or other changed schema objects. Add a new forward migration that applies the required changes to installed databases, with matching rollback behavior, and test a normal upgrade from an already-migrated database rather than only reset-and-reapply.

follow-up migration for databases already at version 20260119045014: in up.sql
remove the obsolete scheduling columns and constraints from workspace_pipelines
and drop the pipeline views, while down.sql restores them exactly. Validate with
a normal forward upgrade from that recorded version, not only a
revert-and-reapply on a fresh database.
Apply the same fix in `@docs/design/workspace-stats.md` around lines 118 - 120:
The design note identifies the same risk for schema objects added or changed in
the historical migration.
Critical: the file reaper's reconcile sweep treated a failed object purge as
progress. purge_file returned Ok(()) even when delete_object caught a store
error, hit an unparseable key, or saw an unknown bucket — and delete_object
itself returned Ok in the latter two cases — so purged_at could be stamped
without reclaiming anything, and the sweep counted these as done. A full batch of
persistent failures then looped forever within a tick.
purge_file now returns PurgeOutcome::{Purged, Pending}: delete_object errors on an
invalid key or unknown bucket, a failure returns Pending, and purged_at is
stamped only on a confirmed removal. The sweep counts only Purged as progress, so
an all-failing batch stops until the next tick and retries.
Also from review:
- Add an id.desc() tie-breaker to the latest-sync DISTINCT ON so a shared
started_at picks deterministically.
- Correct the delete-file endpoint description: deletion is permanent and removes
the stored content (it no longer claims recovery within a retention window).
- Drop the chat tables in a single DROP TABLE statement instead of CASCADE, which
resolves their circular FK without risking silently removing external dependents.
- Fix migration headers that still named removed views/functions
(accounts/initial/workspaces), and scope the connection-sync incremental note
to imports (exports exist and are manual).
- Remove the workspace-stats design sketch from the tree.

Migration and data-layer cleanup, plus two correctness fixes surfaced along the way. Six commits, each self-contained.
1. Unify migration format
down.sql(all 11): one format — a two-line header, flatDROP … IF EXISTSgrouped by object tier in reverse-dependency order,CASCADEonly where a circular FK forces it. Fixed two real reversion bugs: the chatdown.sqlcould not run (circular FK betweenchat_messages/chat_sessions), and the initial migration leaked two functions on revert.up.sql(all table migrations): one house style — prose feature header, descriptive section comments, each column'sCHECKbeside it (chronological/cross-column checks grouped at the table end), one comment per index, fullCOMMENT ON TABLE+ per-column coverage. Also corrected stale doc comments (wrong enum lists,bcrypt→Argon2,(optional)onNOT NULLcolumns, phantom "artifacts"/"quotas"/"steps" references).Verified with a full revert→empty→re-apply cycle and a
pg_dumpDDL diff showing only comment changes — zero structural drift.2. Drop unused DB objects
Removed 5 views and 7 functions no code path reaches (not in
schema.rs, no model, no query; the cleanup logic they duplicated lives in the Rust query layer). Kept the trigger machinery,generate_secure_token, andis_valid_email— all have live callers.3. File lifecycle: fix an object leak, model runs as append-only history
Bug fixed: a manual file delete only soft-deleted the row — it never purged the backing NATS object, and nothing reconciled the orphan (the retention worker only swept
expires_at < now). Manual delete now runs the sameRunBlobStore::purge_fileteardown as retention.Durable reclamation:
workspace_filesgainspurged_at(stamped once the object is gone, with apurged-after-deletedCHECK and a partial index over pending purges).purge_file's object delete is best-effort; on failurepurged_atstays NULL so the reaper retries — a transient object-store outage self-heals.FileRetentionWorkeris renamedFileReaperand now runs an expiry sweep and a reconcile sweep.Runs are append-only audit history: a run keeps its input/audit/output file references even after those files are deleted. A reader resolving a reference to a soft-deleted file gets "gone" (
load_analyzed_documentreturns 404 "analysis deleted" vs 409 "no analysis yet"), distinct from a NULL reference that means the run never had one. The trigger that nulled run references on file delete is removed — it corrupted history by conflating "deleted" with "never existed".input_file_idstaysNOT NULL+ON DELETE CASCADE: the app never hard-deletes an individual file, and the one hard delete — whole-workspace teardown — correctly cascades files and runs away together.Latent fix: once a row is soft-deleted,
trigger_updated_atnow freezesupdated_atatdeleted_at, so a post-deletion system stamp (marking an object purged) can't pushupdated_atpastdeleted_atand violate thedeleted-after-updatedCHECK. Correct for any soft-deletable table.4. Remove unused pipeline scheduling
workspace_pipelinescarriedschedule_cron/schedule_tz/next_run_at, but nothing populated or read them (create always wroteNone; no scheduler; never in a DTO). Dropped the columns, constraints, model fields,is_scheduled(), and the dead constraint variants. (The live scheduling feature is on connections, viaworkspace_connection_schedule+ the sync worker — confirmed complete.)5. Fix the scheduled-sync N+1
The sync worker listed candidate connections, then per connection re-read its schedule (for the cron) and its latest sync —
1 + 2Nqueries per tick.list_scheduled_connectionsnow returns each connection with its cron (the query already joins the schedule), and a new batch query loads the latest sync per connection viaDISTINCT ON. The worker snapshots both in two queries.Notes
docs/design/workspace-stats.md): a tiered sketch for a future workspace-stats feature (run health/storage now; detection metadata and token/cost later, the latter gated on an upstream elide change). Design only — no stats code in this PR.Testing
Full gate green:
cargo +nightly fmt --all -- --check,cargo clippy --all-targets --all-features --workspace -D warnings,RUSTDOCFLAGS=-D warnings cargo doc,cargo test --all-features --workspace,cargo machete. DB reset applies all migrations with no schema drift; the full chain reverts to an empty schema and re-applies cleanly.🤖 Generated with Claude Code
