exportProject.ts, step X4a: each installed program of a PC or notebook as
the FILIUS application of its class, keyed by that class name as Java keys
them, with its settings: servers switched on as the model has them, a web
server's port and virtual hosts, the DNS server's recursion on port 53, the
echo server's port, the generic client's target (none as null, as its
constructor leaves it), the peer count, the personal firewall. E-mail
contents are the next step.
The model lost a web server's virtual hosts switch (useVHost, on for 3 web
servers in the corpus); Swift sets it off on import. The core now has
WebServerConfiguration.virtualHosts (Swift's name), the import carries
Java's value, and the Swift comparison names Swift's error.
Checked by Java: every corpus file, imported, exported and written, loads
with the programs of the original, with no new departure. In the synthetic
model the PC has every program with settings away from the defaults, the
notebook programs without settings (Java's defaults, 3 peers), where Java
makes /peer2peer itself. 12 mutation probes, each loaded by Java, were all
caught.

exportProject.ts is the counterpart of importProject.ts: from the editor
model to the Java view topologyWriter.ts writes. Step X1, the topology:
each node becomes the Java device of its kind with name, position and label
flags; its ports become interfaces or ports; each link a cable drawn
between its nodes; each documentation item a GUIDocuItem. A port's MAC is
the one the simulation uses (the file's, or one derived from the port id);
a router's gateway and DNS server go to every interface, as Java's own
setters do (Java reads the first interface's only). A host with a wireless
card joins a switch by a wireless cable, the only wireless connection Java
makes. The import now enables a host's wireless by Java's card flag, also
without an SSID, where Swift enables it for every SSID.
Checked by Java: every corpus file, imported, exported and written, loads
in Java FILIUS to the topology of the original up to named departures of
the model (a derived MAC where Java rolls one at each load; documentation in
render order, with the model's empty text, Dialog 12 and minimum size where
Java has none or less). A synthetic model adds a label with IP and MAC,
positions between pixels, a five-port switch, a wireless notebook, a
three-interface router and a half-transparent bold text. 17 mutation
probes, each loaded by Java, were all caught.

A notebook that joins a switch's wireless network has its card marked
wireless (NetzwerkInterface.setWireless, Betriebssystem.wireless()), next
to the wireless cable. The reader did not read it, the writer did not write
it, and the Java oracle did not report it, so the Java-against-Java writer
test could not see the loss. Found while exporting the editor model: the
corpus has 18 wireless cards, one at each wireless cable.
The oracle now reports `wireless` per interface; FlsInterface has it; the
writer sets it. The synthetic topology has a wireless card; a mutation
probe that drops it is caught by Java.

topologyWriter.ts writes konfiguration.xml from Java's view of a project:
the version line, the node items (label position, device with name,
host label flags, interfaces or ports), the cable items and the
documentation items. What a device's constructor makes is changed through
getters, as XMLEncoder does, and more is added; fewer than it makes set the
list anew. Cable ends name the port objects the getters return (the writer
now names a getter's result, <void id="Port0" property="port"/>), and each
cable carries the nodes the editor draws it between.
Checked by Java against Java: every corpus file, read and written again,
loads in Java FILIUS (the oracle's loading method, --sha256 ties its result
to the written bytes) to the same devices, names, positions, interfaces,
cables and documentation as the original; so does a synthetic topology with
what the corpus never sets. The oracle and the reader now also report a
cable's drawing ends (JCablePanel ziel1/ziel2): in the corpus the nodes it
joins, for all 183 cables. Mutation probes rewrite the files and let Java
load each mutant.

The e-mail client and server of every host come into the model (core:
EmailClientConfiguration, EmailServerConfiguration, EmailMessage), from
Java's view:
- the server's accounts are those of /mailserver/konten.txt, as Java reads
them at every simulation start; without the file those of the bean list,
which Java would drop;
- the client's account is that of /konten.txt; without it the first of an
older file's kontoListe, which FILIUS 2.14 no longer reads;
- messages are numbered per program in folder order, as Swift does; the
sent folder's are sent; a date is taken only when the file gives one.
Departures from Swift: accounts and messages stay where Swift drops what
fails its checks; first and last name stay apart; a port that is no number
is the default, with a warning. On the corpus the model matches Swift's on
all 13 files; the one Swift error is named (it numbers a mailbox's messages
as their received time and writes that into the konten.txt it rewrites).
The Swift dump now carries the e-mail state, and the file system
comparison leaves out only Swift's hidden state files (and the directories
it makes for them) instead of all of /mail, /mailserver and /peer2peer.

Java's DNS server reads its records from the text file /dns/hosts on every
query. dnsHosts.ts ports that reading (DNSServer.leseRecordListe,
ResourceRecord, Dateisystem.holeDatei) and keeps in the model the records
Java answers: type exactly A, MX or NS, and a name Java accepted. The file
stays in the file system as it is.
Both oracles read 76 hand-picked hosts files (dns-hosts.cases.txt): the
Java oracle through DNSServer.holeResourceRecords (DnsHostsCases), the
Swift oracle through TopologyDNSHostsFileCodec (--dns-hosts). The Java view
matches Java on every case; the model matches Swift except for 33 named
cases in twelve reasons: Java splits at single spaces and LF only, has no
comments or "IN", turns a TTL that is no int into 3600, keeps duplicates,
and empties names with a leading digit. The Swift dump now carries each
server's records; the corpus comparison covers them on 16 files.

importProject carries a host's installed programs into the model with
the settings Swift keeps (web server port, Gnutella peer limit, DNS
recursion and forwarder, personal firewall) and two it does not (the echo
server's port, the generic client's target), plus Java's "switched on".
The Swift oracle writes programs and settings; they match on the 13 files
Swift reads completely.
Intended differences, named in the test:
- every FILIUS program is kept; Swift drops command prompt, text
editor, file explorer, image viewer, echo server and generic client;
- a web server's files stay in /webserver, its document root; Swift
moves them to /www. No program state goes into a host's files.
- multicast_server.fls: maxTeilnehmerZahl refers to a shared Integer
(a button's icon text gap, 4); Swift falls back to 3.

readSystemSoftware lists a PC's or notebook's installed applications with
the settings the model needs: server applications switched on and their
port, the generic client's target, DNS recursion, web server virtual
hosts, Gnutella's peer limit and the personal firewall (on by default,
unlike a router's). Defaults the file leaves out are measured in Java.
All 23 corpus files match Java.
Two examples install an application of their own (Accumulator,
Broadcast), compiled into projekt/anwendungen; it is left out with a
warning, as this reader cannot run Java classes. It must survive a save.

importProject turns a PC's or notebook's Java file tree into Swift's
virtual file system, as Swift's registerVirtualFileSystem does: images
by type or extension from Base64, text by type, unknown types as binary
data or text, unsafe names and collisions left out with a warning, and
the whole import rejected over the project quota. NSString.pathExtension
is measured in the oracle, which now writes every imported file system.
On the 13 files Swift reads completely every file matches, images
compared by hash. Intended: a host whose file has no file system stays
empty, as in Java, where Swift adds the demo files of a new device.
Pending the applications step, the comparison reads our /webserver as
Swift's /www and leaves out the e-mail and Gnutella state files.

importProject carries the DHCP client switch and server settings (hosts
and home routers), a home router's port forwarding rows and a modem's
pairing into the model; the core gains the types, ported from Swift.
The Swift oracle writes them too, and they match on the 13 files Swift
reads completely. Configuration text is now trimmed throughout, as Swift
trims every value it reads (routes and firewall rules included).
Outside those files Swift switches every DHCP server of the Internet
examples off: their "aktiv" refers to a shared Boolean it cannot follow.

importProject carries the system software settings into the model the
core runs: switch SSID and learning time (an SSID Java would roll comes
from the node id, as in Swift), a host's wireless network, manual routes,
RIP and the firewall of every router and home router. The Swift oracle
writes these settings too; they match on the 13 files Swift reads
completely.
A router's default gateway — its first interface's, which Java routes to
(Weiterleitungstabelle.holeTabelle) — is imported into the router's
device configuration. Swift's model drops it; in internetwork_komplett
the way back from 141.99.5.10 depends on it. A test pings across three
routers in the core, with and without it.

readSystemSoftware adds to each node what the topology needs from its
system software: a switch's SSID and learning time, a host's wireless
SSID, a router's RIP switch, the manual routes and the firewall of a
router or home router. All 23 corpus files match Java.
- A router's firewall is one object its constructor hangs in two places;
the corpus writes it under the web server's "konfig" plug-in. The
places are merged.
- The decoder keeps entries a constructor made in a map, reached by
get(key) (installed applications), like the elements of a list.
- The Java oracle loads every file twice and writes values that differ
as null: what FILIUS rolls (MACs, a switch's SSID) without text search.

importProject builds what the simulation core runs from Java's view of a
file: nodes with kinds and ports, links between port ids, device and
interface IP configurations, documentation items with Swift's derived
ids. The core gains the model types it needs (node, link, graph,
documentation item), ported from filius-ipad.
Checked against the Swift import, which the Swift oracle now writes in
full (corpus.swift.json, "state"), on the 13 files Swift reads
completely. Two differences are intended and named in the test:
- a device the file leaves unnamed has Java's default name
("Switch / WLAN"), not Swift's;
- multicast_server.fls: useIPAsName refers to a shared Boolean that
Swift cannot follow; Java shows the IP address, and so do we.
All 23 files import with as many devices and cables as Java has, and an
imported example pings across its router in the core.
Port counts of switches and routers follow Java's lists instead of
Swift's guess from references.
