The Varnish Cache project recently released varnish-5.2, and I have wrapped packages for Fedora and EPEL.

While there are a few additions to the VCL language from varnish-5.0 and varnish-5.1, existing VCL for 5.0 or 5.1 should work without changes on varnish-5.2.

I have pushed varnish-5.2 to Fedora Rawhide. Fedora 27 is in freeze waiting for its GA release now in November, but I will probably push varnish-5.2 to f26 and f27 some time after the the release.

Those who need varnish-5.2 for EPEL may use my COPR repositories at https://copr.fedorainfracloud.org/coprs/ingvar/varnish52/. The repositories include varnish-5.2 based on the fedora package, matching varnish-modules and an assorted selections of vmods. The packages are compatible with EPEL 6 and 7.

The following vmods are available

Included in varnish-modules:

  • vmod-cookie
  • vmod-header
  • vmod-saintmode
  • vmod-softpurge
  • vmod-tcp
  • vmod-var
  • vmod-vsthrottle
  • vmod-xkey

Packaged separately (COPR only for now):

  • vmod-geoip
  • vmod-basicauth
  • vmod-curl
  • vmod-digest
  • vmod-memcached
  • vmod-querystring
  • vmod-rfc6052
  • vmod-uuid

As always, feedback is warmly welcome. Please report bugs in varnish and varnish-modules via Red Hat’s Bugzilla. Bugs in the vmod packages not yet available in fedora may be reported to me at ingvar(a)redpill-linpro.com.

Comparison of different compression tools

Working with various compressed files on a daily basis, I found I didn’t actually know how the different tools performed compared to each other. I know different compression will best fit different types of data, but I wanted to compare using a large generic file.

The setup

The file I chose was a 4194304000 byte (4.0 GB) Ubuntu installation disk image.

The machine tasked with doing of the bit-mashing was an Ubuntu with a AMD Ryzen 9 5900X 12-Core ... [continue reading]
