Varnish Software (VS) writes and maintains a fair number of VMODs for Varnish Cache. This also includes major VMODs that can be considered as part of - or very close to - core Varnish functionality.
How did VMODs get used before?
The normal way of using a VMOD (in the Varnish community) was to do a git checkout from Github, build it from source and run it. This procedure was totally fine when only a single VMOD was required, but this formula got very hairy and time consuming as soon as more than a single VMOD was required. Developers, maintaining or shaping new features, were also affected by this way of building a VMOD, which left something to be desired.
How are VMODs used now?
To make both parties (VS and users) happier, we have decided to combine the simple VMODs (with no third-party/library dependencies) into a single-collection source package.
The following VMODs have been merged into a single project:- Cookie
- Header
- Saintmode
- Softpurge
- Tcp
- Var
- Vsthrottle
- Xkey
Hopefully this will significantly simplify the installation of VMODs, both for users installing from source and those using pre-packaged versions.
Important info:
Tarball distribution is here.
Package available for Debian/Ubuntu distro: https://packages.debian.org/stretch/varnish-modules.
The authoritative location for development of these VMODs is now varnish-modules. Releases of this tree will be a tarball with a proper changelog.
Here are more details on how releases for this and future development will work: https://www.varnish-cache.org/lists/pipermail/varnish-dev/2016-March/008800.html
