Although mainly hypothetical, it would still be possible to get
response from the server for an acs resend request. (This exception
is allowed in MsgType::handle.)
I also noticed that the response may well be a message from an older
session still.
This patch just removes that exception by only passing login requests
to sub handle in the raw_transport loop.
Test plan:
[1] Verify normal login procedure for raw.
[2] Check a few acs resend requests in raw. They should terminate without
a response.

Moving timeout logic to one routine (with unit test).
This further implements two suggestions from Kyle and Larry:
[1] You could use a client_timeout of 0 to specify no timeout at all.
[2] Have the client_timeout default to the timeout if not defined.
Test plan:
[1] Run t/db_dependent/SIP/SIPServer.t.
[2] Test login timeout for raw and telnet.
[3] Check ACS status message for timeout value. Should match policy
timeout from institution.
[4] Test client timeout (zero and non-zero).
[5] Remove client timeout. Test fallback to service.
[6] Remove service timeout too. Test fallback to 30 at login.

Amended to incorporate Srdjan's suggestion to move get_timeout to

raw_connection was not behaving correctly if an invalid string was
passed or a login failed.
It was not checking that the login succeeded ( it checked that account
existed not that it contained data and it existed even if login failed)
and so failed logins instead of aborting immediately fell through into
the sip_protocol_loop, forcing that to timeout invalid connections.
It now checks that account has id set and returns if not.
The timeout alarm is now set on the while loop, in normal running this
should not be triggered as the socket is opened and the first data
should be a login message and the while loop should only iterate once,
but lets not go into an infinite loop due to unforeseen circumstances.
I have reindented the routine as the flow was not clear (the while was
not indented at all.
Also if using Net::Server::PreFork when a new connection comes in you
may be handed the the successful login parameters from a preceding call.
Because of this you could successfully transmit transactions and Koha
would carry them out without having received a valid login ( and
possibly with the wrong account details!) We now delete any existing
account for new connections.

Debugging various problems in SIPServer and control of it, found it
could loop on unread buffers (e.g. the LF of a CRLF if it was only
expecting CR) making it unresponsive to signals.
Reworked the input loop with an eye to removing unnecessary whiles
and replacing the while(1) by a while( connection valid)
Enhanced the timeout code by wapping in an eval.
Moved the logic from SIP_read_packet into the server itself

This patch fixes breakage introduced by the patch for bug 13506
that prevented SIP2 clients from authenticating themselves over
the telnet transport. Attempts to do so would manifest by the
SIPServer backend crashing and the connection getting closed.
To test:
[1] Use the stock SIPServer config, etc/SIPconfig.xml, and ensure
that the database contains a staff user whose username is 'term1'
and password is 'term1' that has the circulate permission.
[2] Start SIPServer, telnet to port 8023, and attempt to log in. The
connection will be aborted:
$ telnet localhost 8023
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
login: term1
password: term1
Connection closed by foreign host.
[3] Apply the patch and restart SIPSever, then repeat step 2. This time,
the login should succeed:
$ telnet localhost 8023
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
login: term1
password: term1
Login OK. Initiating SIP

For historical reasons the SIPServer and SIP modules
have used an extra module path in addition to the
standard Koha one. This has caused numerous irritants
in attempting to set up scripts and basic tests. It
does not help in attempting to modify or debug
this code
This patch changes the package value in the modules
under the C4/SIP directory and makes calls to
them use the full package name.
Where the export mechanism was being short circuited
routines have been explicitly exported and imported
declarations of 'use ILS' when that module was
not being used and which only generated warnings
have been removed.
As a lot of the changes affect lines where
an object is instantiated with new. The opportunity
has been taken to replace the ambiguous indirect
syntax with the preferred direct call
In intializing ILS the full path is added as this
will not require any changes to existing configs.
I suspect this feature is unused, and adds
obfuscation rather than flexibility but have kept
the feature as we need this change in order to
rationalize and extend the testing of the server.
The visible difference is that with the normal Koha
PERL5LIB setting. Compilation of Modules under C4/SIP
should be successful and not fail with unlocated modules,
allowing developers to see any perl warnings
All the SIP modules can now be run through the tests
in t/00-load.t now except for SIPServer itself

Koha's SIP server accepts timeout parameters, but those parameters
are only used for the login portion of a telnet transport session.
Other than that, they are ignored, and as long as whatever opened
the connection keeps it open, it will stay open indefinitely.
Test Plan:
1) Set the timeout setting on your SIP server to 10 seconds
2) Modify misc/sip_cli_emulator.pl, add "sleep 100;" directly after line 91
3) Start your SIP server
4) Run the modified sip script with valid parameters
5) Watch the SIP server stderr
6) Note that even though the script waits far too long before continuing,
the SIP server never kills the connection, and the requests the cli
script makes come back with valid data.
7) Apply this patch
8) Restart your SIP server
9) Repeat step 4
10) Note that this time you see "SIP Timed Out!" in the SIP server
stderr and when the script finally makes it's request, it doesn't
come back with valid data.

This small patch adds a check on the SIP2 socket connection if it is
IPv6 and resolves socket address accordingly.
Any newer Debian distro would probably default to IPv6 so it would
eventually affect all SIP servers.

If you do a kill -s HUP sipserver_pid the server process
should restart its children.
This was not happening although it was logging the commencement
of the process.
Removed traces of Exporter usage this was always incorrect
this program inherits from Net::Server 'use base' to make inheritance
clearer. Removed unnecessary begin block
made file executable so it can run
added a shebang line so OS knows to invoke perl to compile and run
the file.
I've removed the debug code dumping the config to STDOUT,
it should not have gone into the production version.
One of the first things this program does is close stdout etc and
reopens the sip sockets to them. Assuming you can print to them other
than as part of the sip dialogue is not always safe.

The basic problem is that the SIP logic doesn't know where the
input is coming from. It might be a RAW socket, and it might
be telnet. If it is telnet, although the specs declare a
character set (from MS, unfortunately), they do not specify a telnet
implementation. So you might get telnet handshaking or
renegotiations in the middle of an otherwise peaceful session and
these should not be taken as SIP commands. Patches include a move
towards using $CRLF from Socket to avoid problems w/ foreign platform
mapping \n and \r to \015 or \012.
