Summary

Usage limits become one ordered list of entries stored as the USAGE_LIMITS instance setting. Each entry names the users it applies to, or applies to all users, and carries an optional value per metric (memo count, memo content bytes, storage bytes, upload bytes). The first entry that names a user is that user's whole limit set. The last entry applies to all users and is the default. An unset value is unlimited, as is 0.

This replaces the unreleased per-metric usageLimits/{id} resources and their five RPCs. The feature has not shipped, so the stored shape and the API change without migration.

Why

The earlier shape could give one user a bigger limit but could not say which users share a limit set, and every value was its own resource with its own write path. An ordered list expresses a common limit and bigger limits for chosen users with one concept, precedence that is visible in the list itself, and no merge rule. Field 2 of the entry is kept free for a later labels target so a hosted deployment can express "every user with attribute X" without listing ids.

Changes

  • Store: InstanceUsageLimitsSetting is the list. Validation caps it at 100 entries naming at most 1,000 users, requires exactly one all-users entry in last position, and rejects negative values. With nothing stored the instance behaves as one default entry: 8 KiB per memo, 32 MiB per file. Deleting a user removes them from every entry.
  • API: the setting is read and replaced whole through GetInstanceSetting and UpdateInstanceSetting on instance/settings/USAGE_LIMITS, admin-only on read because entries name users. UserUsage returns the limit set in effect as limits plus limit_index. The refusal error keeps reason QUOTA_EXCEEDED with metric, limit, and usage.
  • Core: usagelimit resolves the first matching entry and checks against it directly.
  • Web: the admin page is one table in stored order with a position column, a note that entries are checked top to bottom and the first match wins, move up and down, a pinned default row, and a "Never applies" flag on entries an earlier entry fully shadows. The dialog pre-fills a new entry from the default so an untouched field keeps the default instead of removing the limit. My Account shows usage against the resolved set.
  • Docs: the design document is rewritten; the API changelog, proto README, and provisioning amendments are updated. A first commit changes the design-document rule so a merged but unreleased design stays editable until release, with later changes recorded as dated amendments.

Verification

  • go test ./... including the store suite on all three drivers, and go test -race for server and core
  • golangci-lint run, go fix -diff, go mod tidy with no changes
  • cd proto && buf lint && buf format
  • cd web && pnpm lint && pnpm test && pnpm build
  • Manual run on a scratch instance: adding an entry naming a user shows it above the default, and that user's account page shows storage against the new limit.

Walkthrough

The pull request replaces per-metric usage-limit resources with one ordered USAGE_LIMITS instance setting. It updates protobuf contracts, storage validation and defaults, user resolution, quota enforcement, and the UserUsage response. The API now reads and replaces the whole setting. The web interface manages ordered entries and displays the effective limits. Tests and documentation are updated, and locale strings are revised for the new settings interface.

Suggested reviewers: boojack

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to ed838

Concurrent quota edits can silently overwrite one another, and localized administrators see the new instructions in English. Resolve or explicitly accept these risks before merging.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Update the stale USAGE_LIMITS key comment.

The comment says the key is "exposed through the usageLimits API, never through the instance settings API." This change removes the usageLimits API. USAGE_LIMITS is now read and replaced through GetInstanceSetting and UpdateInstanceSetting. The comment now tells maintainers the opposite of the real behavior.

Proposed fix
-  // USAGE_LIMITS is the key for per-user usage limits. Store only; exposed
-  // through the usageLimits API, never through the instance settings API.
+  // USAGE_LIMITS is the key for the ordered usage limits list, read and
+  // replaced whole through the instance settings API.
   USAGE_LIMITS = 9;

Review comments at @store/usage_limit.go:
- Around line 85-93: Update the validation loop around `limit.UserIds` to add
each entry’s ID count to `userCount` and enforce `MaxUsageLimitUsers` before
scanning for duplicates. Remove the later count increment and cap check so
oversized entries are rejected before the quadratic duplicate scan.

Review comments at @web/src/components/Settings/usageLimitValues.ts:
- Around line 26-27: Update toLimitInput and the form save flow so an untouched
usage-limit field preserves its original bigint instead of rounding or
converting a displayed zero into unlimited; use an exact, reversible
representation if the form cannot retain the original value.
- Around line 45-46: Update the decimal-input conversion around
inputUnit(metric) to reject values whose converted byte count is non-finite or
outside the supported integer range before calling BigInt; return the
invalid-input result so oversized pasted values do not throw during render.

Review comments at @web/src/hooks/useUsageLimitQueries.ts:
- Around line 30-35: Update the usage-limit mutation in mutationFn to include
the stored setting revision or equivalent precondition in the
updateSetting.mutateAsync request, and surface revision conflicts so the editor
requires a refresh instead of overwriting newer changes.

- Line 635: Translate the new quota-management strings, including order-note,
the entry actions, and removal guidance, into each affected non-English locale;
preserve the existing localized interface text rather than using English
replacements.

A merged design keeps changing until the feature ships, so freezing it at
merge locks in a draft. Designs stay editable until the feature is in a
tagged release; after that, later changes go into a dated Amendments
section instead of rewriting the body. Record the usage limits key in the
provisioning amendments.
Replace the per-metric usageLimits resources with one USAGE_LIMITS
instance setting: an ordered list where each entry names the users it
applies to, or applies to all users, and carries an optional value per
metric. The first entry that names a user is that user's whole limit set;
the last entry applies to all users and is the default. An unset value is
unlimited, as is 0. Field 2 of the entry is kept for a later labels
target.

- Store: validate the list (at most 100 entries naming at most 1,000
  users, checked before the duplicate scan; exactly one all-users entry,
  last), serve a built-in default of 8 KiB per memo and 32 MiB per file
  when nothing is stored, and drop a deleted user from every entry.
- API: read and replace the setting whole through GetInstanceSetting and
  UpdateInstanceSetting, admin only on read because entries name users.
  Remove the five usageLimits RPCs. UserUsage returns the limit set in
  effect and its index. The refusal error keeps metric, limit, and usage.
- Core: resolve the first matching entry; checks read the entry directly.
- Web: one table in stored order with position numbers, a note that the
  first matching entry applies, move up and down, a pinned default row, a
  flag on entries an earlier entry shadows, and a dialog that pre-fills new
  entries from the default and keeps the stored value of fields the admin
  did not touch. My Account shows usage against the resolved set.
- Docs: design document rewritten; API changelog, proto README, and
  provisioning amendments updated.
