Documentation

See the docs/ directory. It should also be available in html format at: https://sipp.readthedocs.io/en/latest/

Build a local copy using: sphinx-build docs _build

Building

This is the SIPp package. Please refer to the webpage for details and documentation.

Normally, you should be able to build SIPp by using CMake:

cmake .
make

The SIPp master branch (3.7.x) requires a modern C++11 compiler.

There are several optional flags to enable features (SIP-over-TLS, SIP-over-SCTP, media playback from PCAP files and the GNU Scientific Libraries for random distributions):

cmake . -DUSE_SSL=1 -DUSE_SCTP=1 -DUSE_PCAP=1 -DUSE_GSL=1

Static builds

SIPp can be built into a single static binary, removing the need for libraries to exist on the target system and maximising portability.

This is a fairly complicated process, and for now, it only works on Alpine Linux.

To build a static binary, pass -DBUILD_STATIC=1 to cmake.

Two Alpine-based Dockerfiles are provided, which can be used as a build-environment. Use either Dockerfile or Dockerfile.full in the following commands:

git submodule update --init
docker build -t sipp-build -f docker/Dockerfile docker
docker run --rm -v $PWD:/src sipp-build

Support

I try and be responsive to issues raised on Github, and there's a reasonably active mailing list.

Making a release

Update CHANGES.md. Tag release. Do a build.

Make sipp.1 by calling:

help2man --output=sipp.1 -v -v --no-info \
  --name='SIP testing tool and traffic generator' ./sipp

Then:

mkdir sipp-$VERSION
git ls-files -z | tar -c --null \
   --exclude=gmock --exclude=gtest --files-from=- | tar -xC sipp-$VERSION
cp sipp.1 sipp-$VERSION/
# check version, and do
cp ${PROJECT_BINARY_DIR:-.}/version.h sipp-$VERSION/include/
tar --sort=name --mtime="@$(git log -1 --format=%ct)" \
      --owner=0 --group=0 --numeric-owner \
      -czf sipp-$VERSION.tar.gz sipp-$VERSION

Upload to github as "binary". Note that github replaces tilde sign (for ~rcX) with a period.

Create a static binary and upload this to github as well:

sudo docker build -t sipp-build docker &&
  sudo docker run -it -v $PWD:/src sipp-build

Note that the static build is broken at the moment. See ldd sipp.

Contributing

SIPp is free software, under the terms of the GPL licence (see the LICENCE.txt file for details). You can contribute to the development of SIPp and use the standard Github fork/pull request method to integrate your changes integrate your changes. If you make changes in SIPp, PLEASE follow a few coding rules:

Please stay conformant with the current indentation style (4 spaces indent, standard Emacs-like indentation). Examples:

if (condition) {        /* "{" even if only one instruction */
    f();                /* 4 space indents */
} else {
    char* p = ptr;      /* C++-style pointer declaration placement */
    g(p);
}

If possible, check that your changes can be compiled on:
- Linux,
- Cygwin,
- Mac OS X,
- FreeBSD.

Thanks,
