test(java-oracle): TcpRun records TCP as Java FILIUS runs it
Three stories of socket calls on tcp-lan's network (exchange, closedPort, lostData): every frame with TCP flags and numbers, when each call started, returned or failed, and each socket's states. Network building and the packet log move from DhcpRun to ScenarioNetwork. Measured: 3 RTT per attempt (8250 ms at 90 %), an orderly close after a failed send, TIME_WAIT of 3 RTT, the passive side closing by itself on FIN, one SYN only (Java's retry loop ends after the first timeout).

## TCP zur Laufzeit
|
||||||
|
|
||||||
|
`TcpRun` spielt auf dem Netz von `tcp-lan` (Server 192.168.0.10, Clients .20
|
||||||
|
und .30) einen festen Ablauf von Socket-Aufrufen ab, wie Filius' Anwendungen
|
||||||
|
sie machen, den Server in einem eigenen Thread. Es schreibt nach
|
||||||
|
`tcp-java-<ablauf>.java.json` die Frames jeder Karte (mit TCP-Flags,
|
||||||
|
Sequenz- und Bestätigungsnummer), wann jeder Aufruf begann, zurückkam oder
|
||||||
|
scheiterte, und jeden Zustand jedes Sockets (alle 2 ms abgefragt). Netzbau
|
||||||
|
und Mitschnitt teilen `DhcpRun` und `TcpRun` in `ScenarioNetwork`.
|
||||||
|
|
||||||
|
* `exchange`: Verbindung zu Port 80, `GET /`, Antwort 3000 × `x` (drei
|
||||||
|
Segmente), der Client schließt, der Server eine Sekunde nach
|
||||||
|
`CLOSE_WAIT`.
|
||||||
|
* `closedPort`: Verbindung zu Port 81, auf dem niemand lauscht.
|
||||||
|
* `lostData`: verbunden, dann gehen alle Frames verloren
|
||||||
|
(`Verbindung.setDrop`, wie der Paketverlust des Kerns), während der Client
|
||||||
|
sendet; der Verlust endet, wenn `senden` scheitert.
|
||||||
|
|
||||||
|
Gemessen (30.09.2026, 90 %, RTT 2750 ms), was Swift anders macht:
|
||||||
|
|
||||||
|
* Jeder Versuch wartet 3 RTT (8250 ms): Daten gehen dreimal hinaus (1720,
|
||||||
|
9970, 18220 ms), `senden` scheitert 8250 ms nach dem dritten.
|
||||||
|
* Scheitert `senden`, schließt Java ordentlich: FIN, ACK, FIN, ACK. Swift
|
||||||
|
setzt den Socket ohne FIN auf CLOSED.
|
||||||
|
* `TIME_WAIT` dauert 3 RTT (8250 ms; oder bis zum nächsten Segment), nicht
|
||||||
|
eine RTT.
|
||||||
|
* Die Gegenseite schließt von selbst: Kommt ein FIN, geht Javas
|
||||||
|
Socket-Thread aus `listen` in `close` und sendet sein FIN sofort
|
||||||
|
(`LAST_ACK` rund 60 ms nach dem FIN), nicht erst, wenn die Anwendung
|
||||||
|
`schliessen` aufruft.
|
||||||
|
* Der Client sendet nur **ein** SYN: Nach dem ersten Zeitablauf setzt
|
||||||
|
`connectClientMode` `closeSocket`, und die Schleife über drei Versuche
|
||||||
|
endet (`verbinden` scheitert nach 3 RTT). Der Server-Socket wiederholt sein
|
||||||
|
SYN+ACK nie.
|
||||||
|
* Startnummern aus einem Zähler über alle TCP-Sockets (1000000, 2000000, …),
|
||||||
|
wie im Kern; der freie Port ist zufällig.
