Tensei-Data 1.13.1 Announcement

Submitted by Jens Grassel on Thu, 05/18/2017 - 14:24

We just released version 1.13.1 of Tensei-Data.

Summary of Changes

Some bugfixes regarding export and import of cookbooks were made. Also a change under the hood regarding a secure number generator was made to prevent systems with low entropy to block forever.

Remember that a free license is included in each release which allows the usage of one agent and up to three transformation configurations. For details see our license information page.

To try it out simply run vagrant init wegtam/tensei-demo; vagrant up --provider virtualbox.

Changed

  • cookbook export now in binary format

To convert your old exports into the new format you can simply gzip them but be sure to have them encoded using UTF-8.

Gzip old cookbook

% gzip -9 my-old-cookbook.json

Convert and gzip wrong encoded old cookbook

% iconv -f OLD-ENCODING -t UTF-8 my-old-wrong-encoded-cookbook.json | gzip -9 > my-old-cookbook.json.gz

Fixed

  • forcing import of cookbook fails
  • cookbook import fails if file encoding was changed
  • strong secure random number generator blocks endless on systems with low entropy
  • usage of java.io.FileInputStream and java.io.FileOutputStream considered harmful

Update demo version

To update the demo version you can use the following sequence of commands. Please export your cookbooks before doing this if you don't want to loose them.

vagrant box update
vagrant destroy
vagrant up
