X Pseudo-Terminal (PTY) File-Manager
X ==================================
XOverview:
X
X Pseudo-Terminals (PTY's) are a kind of Interprocess
XCommunication (IPC), which are known on a wide variety of UN*X
Xcomputers, mostly BSD-like systems. They behave like any other SCF
Xdevices like terminals and printer but are in fact pseudo-devices i.e.
Xexists only in the memory the system.
X
X PTY's have two distinct end-points, namely server-pty and
Xclient-pty, which behaves by default differently. A server-pty
Xsymbolizes the terminal and a client-pty forms the connection to the
Xapplication programs. This implies, that the server-pty provides RAW
Xinput and output whereas the client-pty can handle line-editing, echoing
Xand so on.
X
X With this mechanism many programms can share one real device,
Xlike a real terminal, via one server which multiplexes all connected
Xserver-pty's. Something similar can be reached with the usage of pipes,
Xbut pipes have the disadvantage of being not a tty-device with echo,
Xline-editing, interrupt-chars etc.
X
XExamples:
X - virtual Terminals: one program multiplexes ptys and displays the
X outputs on a real Terminal (there exist a programm called 'screen'
X which does exactly this).
X - In a TCP/IP environment, the program 'rlogin' starts a
X login-process on a tty on the remote machine.

X
XFig. 1: Typical Server-Client Application
X
X
XImplementation:
X
X With OS9-68000 (OSK) a own File-Manager was written, which
Xhandles both types of PTY's : the client-ptys, and the server-ptys
Xwhile using only *one* descriptor (device) for each. Server-ptys must
Xbe opened as "/pty/any_valid_name" , client-ttys must be opened (i.e.
Xconnected) with "/tty/any_valid_name". PTY's can be also implemented
Xwith the usage of a special device-driver for the SCF, but this has
Xserveral draw-backs :
X
X - A System-Global Variable has to be introduced for the rendezvous
X of the PTY-pairs (not implementation independent).
X
X - For each pair of PTY's there must exist two Device-Descriptors
X (waste of memory and Device-Table-entries).
X
X - The number of PTY's pairs are limited !!
X
X - Block-writes in RAW modus has still to be done on a char-by-char
X basis with single calls to the driver, as required by the SCF
X
X When creating a server-PTY the Filemanager searches a list of
Xalready openend server-ptys for the same name. The name can be any
Xlegal OS-9/68000 Filename (no distinction between upper- and
Xlower-case). When a identical name is found, the Filemanager return a
XE_CEF-error (File already exists), otherwise the Pathdescriptor (PD) is
Xinserted into this list and some initialisation is done (allocating
XData-Buffers etc.). Then the list of client-PTYs is searched for any
Xalready opened tty; iff found, the pair is connected and a DCOn-Signal
Xis sent, if specified by the client-PTY.
X
X When opening a client-PTY the Filemanager looks thru the above
Xmentioned list for a already openend server-pty. If found, it sets a
Xspecial pointer pointing to the PD of the server-pty. (the Filemanager
Xbasicly distincts server-pty's and client-pty's by the value of this
Xpointer). If a server-PTY couldn't be found, the open-call returns, but
Xnearly any further i/o call will issue an E_HANGUP error. Only the
Xfollowing calls will return without an error:
X - close()
X - getstat: SS_DevNm and SS_OPT
X - setstat: SS_EnRTS/SS_DCOn, SS_DsRTS/SS_DCOff and SS_OPT
XIf the client-tty has specified an DCOn-signal, the later connecting pty
Xwill send it to the tty 'hanging around'.
X
XRemark:
X There exist only *one* named server-pty but there can be many
X client-ptys listening (although its possibly to I$DUP a
X server-pty-fd).
X
XA client-tty may be opened with the S_ISHARE-bit on; in this case
Xthere is only one client-tty allowed.
X
X When closing a Server-Pty, the Filemanager searches for all
Xclient-pty's and sets the special pointer to NULL indicating a
XHANGUP-condition. He also tries to send a SIGHUP-Signal (value is
Xchangeable via the _ss_dcoff()-Call) to the last/current user of a
Xclient-pty. Any further I/O calls to a disconnected client-pty will
Xissue a E_HANGUP-Error!
X
X Closing a client-pty requires no special tasks but clearing all
Xpending Signals (e.g. pending _ss_signl() ), which is done automaticly.
X
XIf a server-pty is opened with the S_IFDIR-bit set, further reads will
Xreturn pseudo-directory-entries for all opened server-ptys. A command
X'dir /pty' will therefore return the names of all current opened
Xserver-ptys.
X
X Although total compatibility to a SCF-Device was intended, the
XPTY-Filemanager does differ in some small aspects from the SCF. The
Xreason for that were some features of the SCF, which I do consider
Xfaulty e.g. with a ReadLn-count of one the only character you can read
Xis CR and nothing else (:-( ).
X
XDifferences:
X - a Readln-Call with a character count of 1 will return the next
X character available.
X
X - The Read-Call may behave differently: kbich and kbach will
X abort with the appropriate Error-codes. No Echo, but raw-byte-transfer.
X
X - Any signal < 32 and > 1 (SIGWAKE) will abort a pending I/O with an
X error-code of the signal (this should be made standard).
X
X - A close of a server-pty will only generate a SIGHUP (see SS_DCOff)
X and will *not* abort the reading processes (the program 'com'
X seems to have problems with that !).
X
X - the special IOSTOP or IOCONT SetStats blocks transmisson
X of data in any direction (read and write). Read/Writes are still
X possibly, but will block if the internal buffers are full.
X Beware of Deadlocks !!!
X
XDescriptions of operation:
X
X- Read-calls:
X absolute raw-read, ignores echo-parameter, but unterstands kbich,
X kbach, xon, xoff and psc of the other end.
X
X- Write-calls:
X absolute raw-write .... but sends QUIT and INT if set, and handles
X xoff/xon and psc handling of the other side.
X
X- Writeln-calls:
X recognizes upc(only if required via -DUPCHAR), tabch, tabs, alf,
X pause and returns on recognizing the eor-char (normaly CR).
X Sends QUIT and INT if set.
X
X- Readln-calls:
X recognition of echo, upc, bso, bse, bspchar, eorchar, alf (when
X echoing), kbich, kbach, eof, delchar, rprchar, dupchar and pause.
XCAVEAT:
X - A final EOR in the input-stream is not necessary and this was
X deliberatly avoided !!!
X - The maximum readln-count is 256 Bytes (like in the SCF). You can
X specify more but the Filemanger will cut it to 256...
X
X- GetStat-calls:
X supported codes are: SS_Opt, SS_Ready, SS_EOF, SS_DevNm (returns the
X complete path-name of the pty), SS_BlkRd.
X
X- SetStat-calls:
X supported codes are: SS_Opt, SS_SSig, SS_Relea, SS_EnRTS, SS_DsRTS,
X SS_DCOn, SS_DCOff, SS_BlkWr, SS_IOSTOP and SS_IOCONT.
X
XNot supported are null (for padding).
X
X
XDescription of GetStat-Codes:
X
X - SS_Opt:
X copy the first 28 Bytes of the option part to the users
X (a0)-register.
X
X - SS_Ready:
X return number of chars available for reading in users d1
X register, or return E_NOTRDY if no input is available.
X
X - SS_EOF:
X always returns 0 in callers d1 register (like SCF).
X
X - SS_DevNm:
X return the null-terminated path-name of the pty into the callers
X (a0)-register (e.g '/tty/testtty').
X
X - SS_BlkRd:
X Read x (in users d2-register) Bytes into buffer, users
X (a0)-register is pointing to.
X
X
XDescription of SetStat-Codes:
X
X - SS_Opt:
X copy the first 28 Byte from users (a0)-register into the option
X part of the pathdescriptor.
X
X - SS_SSig:
X Send signal in users d2-register on receiving the next
X available character. If another Process is waiting for input,
X return an E_NOTRDY error.
X
X - SS_Relea:
X Clear a SS_SSig action...
X
X - SS_EnRTS:
X see SS_DCOn
X
X - SS_DsRTS:
X see SS_DCOff
X
X - SS_DCOn:
X if a connection between a pty/tty pair is occurring, this signal
X will be sent (will be ignored if not set)!
X
X - SS_DCOff:
X Send Signal in users d2-register on closing the server-pty
X (Carrier-lost condition). The Default signal is SIGHUP (Value: 4).
X
X - SS_BlkWr:
X Write x ( in users d2-register ) Bytes from buffer users
X (a0)-register is pointing to.
X
X - SS_Screen (Subfunction ScrOut):
X Optional, like BlkWr. exists only on ST's (Cumana Implementation).
X
X - SS_IOSTOP:
X sets a flag, which blocks any handshake. If you still write/read
X to/from a stopped connection, deadlock may occur when the internal
X buffers are full/empty, due to the missing handshake!!
X
X - SS_IOCONT:
X Reallow further handshake by activating any reading process of
X either side.
X
XExample of SS_IOSTOP/SS_IOCONT:
X write( tty, "Hello ", 6); /* transfer 'Hello ' to the other side
X * if a read is pending transfer it
X * immediatily
X */
X _ss_iostop(tty); /* freeze any reading from/to pty/tty
X * the maximum the reading process can
X * read without blocking is up to the
X * string 'Hello' (not the blank)
X */
X write( tty, "World\n", 6); /* this write will not block if there is
X * enough room in the internal buffer
X */
X sleep (10); /* wait .. not I/O will occur */
X _ss_iocont(tty); /* reallow further transmission,
X * any pending read will be continued;
X * by completion of the read() the block on
X * the writing process will be released
X */
X
XFinal Thoughts:
X
X Some tests have shown, that this Filemanager is about 100%
Xfaster than an orthodox implementation with a special device Driver for
Xthe SCF when doing readln/writeln calls. By using only read/write calls
Xsome can expect even much more throughput (no line-editing stuff etc..).
X
XBUGS:
X
X This Filemanager seems to have problems in OSK-Versions lower
Xthan 2.0 (-> e.g. 1.2). I think the 'openend-Path'-list isnt supported
Xby the Kernel (IOMan); maybe the Filemanager should do it itself ??
X
XThings to do:
X - more lineediting (emacs-style, history ?)
