# Integrity-preserving performance contracts
|
||||
|
||||
These are implementation guarantees and regression-test boundaries, not a
|
||||
security certification or production load-test result. Feature-specific policies
|
||||
and help remain in the owning modules' English and German documentation topics.
|
||||
|
||||
## Refreshes, edits and table rendering
|
||||
|
||||
The shell runs at most one module-load refresh per authority generation. Multiple
|
||||
invalidations coalesce into one trailing refresh; stale results and errors cannot
|
||||
replace a newer generation. Focus refreshes are throttled to five seconds and
|
||||
focus/visibility refreshes on hidden pages are suppressed; explicit module
|
||||
invalidations still trigger a read. Authentication/tenant reset disposes the
|
||||
previous controller. Authentication and authorization checks are not cached away.
|
||||
|
||||
Editable modules must reconcile a save against the submitted draft and accepted
|
||||
server revision: edits made while a request is pending remain dirty. Completion
|
||||
must be fenced by security-relevant authority and selection, not merely an auth
|
||||
object's reference identity. A harmless profile refresh must not discard an
|
||||
accepted newly created ID and invite a duplicate create. An old account's mutation
|
||||
continuation must not reload its catalogue into the current account's page.
|
||||
|
||||
DataGrid precomputes first-occurrence row indices once for client sorting and
|
||||
filtering. Duplicate object references, primitive values, `NaN` and sparse arrays
|
||||
retain `Array.indexOf` behavior. Comparator order, visible pagination, server-side
|
||||
pagination, sizing and resize rules are unchanged. Do not replace this with a
|
||||
last-occurrence map or change ordering as a side effect of an optimization.
|
||||
|
||||
## Conditional responses
|
||||
|
||||
The shared JSON GET middleware performs route handling, including authorization,
|
||||
before considering `If-None-Match`. It buffers only responses up to 1 MiB for a
|
||||
body-derived ETag. Known larger responses bypass buffering; an unknown-length
|
||||
stream crossing that limit replays its exact prefix and streams the remainder.
|
||||
No data is truncated and no large joined copy is created. The crossing chunk is
|
||||
already producer-owned: this is not a process-wide or route-output memory limit.
|
||||
Empty chunks do not accumulate. Large responses may no longer receive a
|
||||
middleware-generated ETag/304; explicit route ETags remain intact. Small-response
|
||||
cache semantics and credential/language/context `Vary` fields are retained.
|
||||
|
||||
## Shared helpers and concurrency
|
||||
|
||||
Central helpers replace exact live-code duplicates only. Actor precedence,
|
||||
whitespace handling and service-account differences remain explicit owner choices;
|
||||
historical migration code is not redirected to mutable runtime helpers. Connector
|
||||
search ACL token projection keeps its first-seen ordering and existing 500-token
|
||||
cap, stopping work once that cap is reached. Provider schemas are inferred in one
|
||||
pass without storing a second list of every column value.
|
||||
|
||||
The keyed-list three-way merge retains insertion anchors when unrelated fields
|
||||
change. Concurrent additions use deterministic ordering; contradictory anchors
|
||||
produce a collection-order conflict instead of silently relocating an item.
|
||||
No existing endpoint is newly opted into merge behavior by this change.
|
||||
|
||||
SQL JSON authorization predicates support the explicitly tested SQLite and
|
||||
PostgreSQL dialects, retain exact string membership and reject unsupported
|
||||
dialects. Apply tenant and authorization predicates before counting/pagination;
|
||||
never page a broader result first and filter away unauthorized records afterward.
|
||||
SQLite execution and PostgreSQL SQL compilation are not substitutes for a
|
||||
deployment's PostgreSQL concurrency and representative-data load tests.
|
||||
|
||||
## Migration connection URLs
|
||||
|
||||
Alembic preserves the configured database URL exactly in online and offline
|
||||
migration modes, including percent-encoded credentials and PostgreSQL Unix-socket
|
||||
paths. Escaping applies only at its ConfigParser boundary; operators must not
|
||||
double-escape `%` in `DATABASE_URL` or alter working connection credentials to
|
||||
work around interpolation errors. This does not change the target database,
|
||||
authentication, TLS policy, or migration contents.
|
||||
|
||||
## Deutsch: Integrität vor Geschwindigkeit
|
||||
|
||||
Der zentrale Modul-Refresh bündelt gleichzeitige Auslöser und verwirft veraltete
|
||||
Ergebnisse einschließlich Fehlermeldungen. Ein Wechsel von Anmeldung oder Mandant
|
||||
beendet die bisherige Generation. Fokusaktualisierungen sind auf einen Auslöser
|
||||
je fünf Sekunden begrenzt. Berechtigungsprüfungen bleiben erhalten.
|
||||
|
||||
Speicherantworten dürfen zwischenzeitliche Bearbeitungen nicht überschreiben.
|
||||
Ein unveränderter Berechtigungskontext mit einem neuen Profilobjekt darf eine
|
||||
bereits bestätigte neue ID oder Revision nicht verwerfen. Umgekehrt dürfen alte
|
||||
Anfragen nach einem Kontowechsel keine Daten in den neuen Kontext übernehmen.
|
||||
Die DataGrid-Optimierung erhält Reihenfolge, Filter-, Seiten- und Größenverhalten.
|
||||
|
||||
Die ETag-Middleware puffert höchstens 1 MiB Nutzdaten zuzüglich eines bereits vom
|
||||
Erzeuger gelieferten Grenz-Chunks. Größere Antworten werden vollständig weitergereicht,
|
||||
nicht abgeschnitten; automatisch erzeugte ETags können dabei entfallen.
|
||||
Autorisierung läuft auch bei bedingten Anfragen. Das ist keine allgemeine
|
||||
Speicherbegrenzung für Routen oder Prozesse.
|
||||
|
||||
Gemeinsame Helfer erhalten die bisherigen fachlichen Unterschiede. Listen-Merges
|
||||
bewahren Einfügepositionen oder melden widersprüchliche Reihenfolgen explizit als
|
||||
Konflikt. Datenbankseitige Autorisierung erfolgt vor Zählung und Seitenauswahl.
|
||||
Regressionstests belegen diese Verträge; reale Provider-, PostgreSQL- und Lasttests
|
||||
in einer repräsentativen Umgebung bleiben Teil der Betriebsfreigabe.
|
||||
|
||||
Alembic übernimmt die konfigurierte Datenbank-URL in Online- und Offline-Läufen
|
||||
unverändert, einschließlich prozentkodierter Zugangsdaten und PostgreSQL-
|
||||
Unix-Socket-Pfade. Die Maskierung erfolgt ausschließlich an der ConfigParser-
|
||||
Grenze; `%` in `DATABASE_URL` nicht doppelt maskieren und funktionierende
|
||||
Zugangsdaten nicht als Umgehung ändern. Zieldatenbank, Anmeldung, TLS-Vorgaben und
|
||||
Migrationsinhalte bleiben unverändert.
