Programs run as generators that yield what they wait for (threads.ts); the
engine resumes them after every event. TCP connect, send, receive, accept
and name resolution exist as such steps; the blocking calls wrap them.
EchoRun records eight stories in Java FILIUS, frames, tables and each
program's window lines; echoJava.test.ts plays them card by card. Not
taken from Java: a connection without a route hangs for ever; a server
switched off leaves its connections' last FIN unanswered.

topologyWriter.ts writes the e-mail server's domain and bean accounts with
their mailboxes, and the e-mail client's three folders and address book.
The client's account is no bean (FILIUS 2.14 has no kontoListe property):
it lives in /konten.txt and is written with the files.
A Java error is not copied: older files keep recipients as strings, which
Java puts into its typed lists unchecked, and its e-mail window fails on
them. The writer writes the AddressEntry Java's own AddressEntry(String)
makes of each; a null recipient is left out. The Java oracle now reports
that reading next to each such string, and our addressEntry matches it on
all 9 in the corpus. The test names the departure (RECIPIENTS_AS_STRINGS)
and checks that it touches man-in-the-middle.fls alone.
Checked by Java against Java: every corpus file, read and written again,
loads with the same e-mail programs as the original, up to that departure.
The synthetic topology adds an e-mail server and client with an account, a
mailbox, three folders, an address book and recipients of every form. 15
mutation probes, each loaded by Java, were all caught. The writer now
writes everything the reader reads of Java's view.

javaBeansWriter.ts writes what java.beans.XMLDecoder reads — the
counterpart of javabeans.ts and the base of the .fls writer. Its input says
explicitly what Java should do: construct a class with typed arguments, call
setters, getters (with statements on their result), methods and indexed
access; an object reached twice is written once with an id and referenced
after. Unlike XMLEncoder it writes what it is given, defaults included.
What XML 1.0 cannot hold (controls, lone surrogates, U+FFFE/F) and a CR,
which XML would read as a line break, are written as <char code>.
Checked by Java itself: nine files of the writer (strings with every kind
of odd unit, all primitive types including NaN, -0.0 and a long beyond
2^53, collections, maps, shared objects, Rectangle, Color, FILIUS beans with
getter chains, arrays, indexed access, a static constant) are read by
XMLDecoder in the Java oracle (BeansDump), which describes what it got and
collects the errors the decoder would only log. Mutation probes regenerate
the files and let Java read each mutant.

The Java view now reads what FILIUS 2.14 keeps for its e-mail programs:
the server's domain, switch and bean accounts with their mailboxes, and the
accounts of /mailserver/konten.txt, which Java reads at every simulation
start and which so win over the bean list; the client's three folders and
address book, and its account from /konten.txt (no bean holds it).
javaEmail.ts ports the bean setters and both file readers
(stringZuListeBenutzerkonten, EmailKonto(String)); javaString.ts Java's
trim, split and StringTokenizer; javaFileSystem.ts the file lookup, now
shared with the DNS server, with the four non-ASCII units Java's
equalsIgnoreCase also takes for an ASCII letter (measured over the BMP).
Checked against Java on the corpus (the oracle dumps the e-mail state) and
on 43 account files read by EmailServer.kontenLaden and
EmailAnwendung.laden (EmailFileCases). Found: older files keep recipients
as strings in the typed lists; a getter copy of the sender is filled and
set back; one short server line makes Java throw for the whole file; a
message with an empty text is lost on reading; a broken last client line
empties the account.

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.

readSystemSoftware adds the DHCP client switch and server settings of
every IP stack, a home router's static NAT table (port forwarding) and a
modem's mode, port and address. All 23 corpus files match Java.
Static DHCP assignments follow setStaticAssignedAddresses: each entry is
split at Java whitespace (the same 25 characters as Character.isWhitespace,
measured over the BMP), and an entry without MAC and IP ends the list, as
Java throws there.

readTopology maps the decoded JavaBeans graph to devices, cables and
documentation items the way SzenarioVerwaltung.netzwerkLaden does: the
kind from the Java class (the palette label is not file data), devices
without bounds at 0,0, interface values through Java's setters. All 23
corpus files match Java field by field.
Found on the way:
- listItems mixed a constructor's elements with added ones; a router's
second interface was lost. Lists now replay add/set in order after the
elements the constructor made.
- The first 0 of a file may be SwingConstants.CENTER; measured like the
getter defaults.
- IP.ipCheck (javaIp.ts) measured on 46 cases: empty tokens skipped,
signs, leading zeros and BMP digits of any script accepted.
- The Java oracle took lower-case MACs in a file for random ones (8
interfaces); it now compares case-insensitively and reports the host
name flags.

First slice of the TypeScript port of the filius-ipad runtime engine,
with 29 tests ported from the Swift suite. Parts not ported yet throw
NotPortedError instead of guessing.
