Session load command is broken

[Michael Jeanson]

[Impact]

Loading a saved lttng session is currently impossible because of a missing file in the package. Trying to load a session results in the following error:

root@session:~# lttng load toto
I/O warning : failed to load external entity "/usr/share/xml/lttng/session.xsd"
XML Error: Failed to locate the main schema resource at '/usr/share/xml/lttng/session.xsd'.
Error: XSD parsing failed
Error: Invalid session configuration

[Test Case]

 * Install lttng

  apt-get install lttng-tools

 * Create, save and delete a session

  lttng create mysession
  lttng enable-event -u -a
  lttng save mysession
  lttng destroy mysession

 * Load the saved session

  lttng load mysession

  * Loading the session should succeed.

[Regression Potential]

 * Regression is very unlikely, we are only adding a missing file to the package.

Hello Michael, or anyone else affected,

Accepted ltt-control into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ltt-control/2.7.1-2~fakesync1.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I tested the 2.7.1-2~fakesync1.1 package from proposed and I confirm the missing file is now included and I can successfully load sessions.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ltt-control - 2.7.1-2~fakesync1.1

---------------
ltt-control (2.7.1-2~fakesync1.1) xenial; urgency=medium

  * Add missing session.xsd liblttng-ctl0 (LP: #1619767)
