e465d1aa4b Bug 15006: [QA Follow-up] Only handle login requests in raw_transport
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.

eb8666357c Bug 15006: Centralize timeout logic and allow zero client timeout
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
SIPServer.pm; this requires some additional mocking in the unit test.
And even makes the test db dependent, as documented.

4f0fd3db55 Bug 15006 Drop raw connection if login fails
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.

NB: This patch requires that the patch for bug 13807 has been applied

94441be435 Bug 13807 Rework main input loop in SIPServer
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
Hopefully this makes the already baroque code easier to navigate
and it did seem the server was the logical place for this
Removed no longer iused SIP_read_packet from Sip.pm

3ec8b27185 Bug 14644: unbreak SIP2 terminal login when using telnet transport
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

d85f757ce7 Bug 7904 Change SIP modules to use standard LIB path
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

03335ab401 Bug 13432 - SIP Server does not respect timeout setting
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.

a5c9947f43 Bug 13252 - SIP2 server should accept IPv6 connections
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.

Tests against running SIP server on an IPv6 box:

http://wiki.koha-community.org/wiki/Koha_SIP2_server_setup#Testing_with_Telnet

before patch:
  disconnects immediately. Log output:
  Bad arg length for Socket::unpack_sockaddr_in, length is 28, should be 16

after patch:

499ff3618c Bug 12263: Fix startup issues blocking response to HUP
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.

8e485c6112 Bug 8271 teach SIPServer.pm to set its own lib path
SIPServer.pm requires that C4/SIP is added to its lib
path This has been done by passing this directory
to it via -I. By using FindBin it can set the path
for itself correctly. This will also work if the C4/SIP
directory tree is moved to a non-standard location
Removed the now redundant -I. from sip_run.sh

Added a variable to sip_run.sh for the koha tree to
highlight a problem with the script if you have multiple
directories in the PERL5LIB environment variable

078ce11e11 Bug 7787: Make the SIP server much more robust.
Be liberal in what we accept, but strict in what we send:
Never exit the server process, but send a SC_RESEND message (96)
to the client if we received anything we don't understand.
 This is consistent with SIP server implementations of other ILSs.

Joe Atzberger (siptest
5aecb46ad0 SIP - Lots of regexp hacking of input streams and verbose debugging feedback.
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.
