What steps will reproduce the problem?
[Ans]1.Provide the entire frame(containing compressed SIP message) as input to
the "decompress" API
2.
3.
What is the expected output? What do you see instead?
[Ans] : I expect the decompression to be successfull but I see it fails.
What version of the product are you using? On what operating system?
[Ans] : Sigcomp rc59 on windows XP
Please provide any additional information below.
I tried to give the entire frame to the "decompress" API but the decompression
failed.
Does the Sigcomp product support only de-capsulated data? i.e. SigComp message
has to be de-capsulated before giving it to the "decompress" API?
Can you please let me know if we can provide the following as input to the
"decompress" API?
- The entire frame(work out all encapsulations automatically)
- IP packet
- TCP/UDP/SCTP packet
Thanks.

The C wrapper is not built inside libsigcomp.a, because the
src/c_wrapper.cxx file is missing from the Makefile.am.
A trivial fix is to add this file to the Makefile.am template.

I've been using libsigcomp to (de)compress SIP messages over TCP. I've hit a
few problems related to TCP segmentation:
1. If I send a single TCP packet that contains multiple sigcomp messages, the
last message is not decoded. This seems to be an error in libsigcomp's buffer
length calculations.
2. If I send a single sigcomp message split over several TCP packets, I get a
decode error. This appears to be because libsigcomp unquotes single 0xff bytes
multiple times (once for each message segment).
3. Through code reading, I have spotted that sending malicious sigcomp message
over TCP can cause libsigcomp to allocate an unbounded amount of memory.
I have a patch for these issues. Do you need me to sign any contributor's
agreement or anything before I send it?

What steps will reproduce the problem?
I've just made cout print to demo.cpp compression ration of manager1->compress
& manager2->compress, it appears that compression ratio is very promissing:
Compression using manager I stat (min/max/avg): 0.906915/1042/1.0841
Compression using manager II stat (min/max/avg): 0.906915/1.30909/1.08502
Perhaps it's the deflat made it bigger?

Add pure "C" wrapper.
This will allow pure "C" project to use libsigcomp.

When compression we MUST only load acknowledged states.
This mean that compression should be loaded from the latest acknowledged
state data.

There are two issues when building libsigcomp on Linux platforms:
1) pthread is not detected by default. The --phtread-prefix is mandatory to
use pthread. The detection should be more lenient.
2) include files are installed directly under $(PREFIX). It is better to
segregate the include files to provide a clean access.
Here is a patch that addresses the two issues.

1.run demo with addSipSdpDictionary();
2.run demo without addSipSdpDictionary();
3.
What is the expected output? What do you see instead?
I found that the result of compression is the same one. I want to confirm that
the demo whethor or not use static dictionary to compress.
What version of the product are you using? On what operating system?
The version is based on your svn source code.
Please provide any additional information below.
