Session load command is broken

Bug #1619767 reported by Michael Jeanson on 2016-09-02
This bug affects 1 person
Affects Status Importance Assigned to Milestone
ltt-control (Ubuntu)

Bug Description


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.

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.
