ABI Compatility Tracking
This directory contains files that can be used to generate an ABI compatibility timeline for libwebsockets. This gives users an idea of where the library has changed and can be used by the developers to see when incompatible changes have been introduced and either increase the library SO version or fix the changes.
The tools used are the abi-* family available at https://github.com/lvc/ and some example output is here: http://abi-laboratory.pro/tracker/timeline/libuv/
The tools download existing source tarballs and git repository to generate this data, so past versions are compared and in-development code can be compared as well.
Although the application is not being included here, FYI the license is dual LGPL2 / GPL2 at your choice.
Installation
The author provides an easy way to install the various tools he provides:
git clone https://github.com/lvc/installer
cd installer
make prefix=/usr/local target=abi-tracker
It will also list any dependencies that you need to install through normal means. (Although in the case of needing "elfutils-libelf-devel", it may crash during install of vtable-dumper without giving a nice list)
Generating the output
Use the lws-abi-update.sh script to download the source files, build them and
generate the output html. The output can be deployed to a directory on a web
server for example. Modify the commented line in lws-abi-update.sh to do this.
As it is configured, lws-abi-update.sh will only download new source - ones that it hasn't built before - so is suitable for use with a cron job.
Viewing the output
The best place to start looking at the data is the timeline/libwebsockets
directory. If your path is on a web server, navigate there, otherwise you could
try:
lynx timeline/libwebsockets/
