Re: [reSIProcate-users] how to convert MsgHeaderScannerFSM to digraph?

[fuliang yuan <fuliangyuan@xxxxxxxxx>]

Byron,

I tested with
To: <sip:12345@host>, <sip:6789@host2>

or
To: <sip:12345@host>
To: <sip:6789@host>

or
UnknownHeader: 123456789, abcdefg


No NFieldName, or NValue states have been used at all.

By the way, my resiprocate stack is compiled with RESIP_MSG_HEADER_SCANNER_DEBUG.

Regard,

Frank

Ok, it looks like that FSM graph is missing some information; there are ways to transition from those single value states to the multi-value states. I am not convinced that these separate multi-value states are necessary. What good is it if the pre-parser rejects

To: sip:bob@foo, sip:joe@foo

When it cannot reject

To: sip:bob@foo

To: sip:joe@foo

If you have code that deals with the latter (and we do, it lives in SipMessage), why should we deal with the former in the MsgHeaderScanner?

Best regards,

Hi Adam,

 How is State 7:ScanWhitespaceAfterNFieldName reached?
Under what condition are NValue and NFieldName  used?

The graph is attached.

Thanks

Hi Adam,

It works fine with GVedit.

Thanks a lot!

Hi,

I dumped MsgHeaderScanner FSM, but have no idea what tool should be used to convert it to diagraph.
Any help is appreciated.
 

You use the "dot" tool, which is part of the "graphviz" software suite. Your OS distribution probably has a package for it (using, for example, apt-get, yum, ports, or the Cygwin installer) -- or you can download it here:
