How To Do Things
================
Remove Runs
-----------
From the dashboard click on the button (PASS/FAIL...) for one of the tests. From the test control panel that
comes up push the clean test button. The command field will be prefilled with a template command for removing
that test. You can edit the command, for example change the argument to -testpatt to "%" to remove all tests.
.Remove the test diskperf and all it's items
----------------
megatest -remove-runs -target ubuntu/nfs/none -runname ww28.1a -testpatt diskperf/% -v
----------------
.Remove all tests for all runs and all targets
----------------
megatest -remove-runs -target %/%/% -runname % -testpatt % -v
----------------
Archive Runs
------------
Megatest supports using the bup backup tool (https://bup.github.io/) to archive your tests for efficient storage
and retrieval. Archived data can be rapidly retrieved if needed. The metadata for the run (PASS/FAIL status, run
durations, time stamps etc.) are all preserved in the megatest database.
For setup information see the Archiving topic in the reference section of this manual.
To Archive
~~~~~~~~~~
Hint: use the test control panel to create a template command by pushing the "Archive Tests" button.
.Archive a full run
----------------
megatest -target ubuntu/nfs/none -runname ww28.1a -archive save-remove -testpatt %
----------------
To Restore
~~~~~~~~~~
.Retrieve a single test
----------------
megatest -target ubuntu/nfs/none -runname ww28.1a -archive restore -testpatt diskperf/%
----------------
Hint: You can browse the archive using bup commands directly.
----------------
bup -d /path/to/bup/archive ftp
----------------
Submit jobs to Host Types based on Test Name
--------------------------------------------
.In megatest.config
------------------------
[host-types]
general ssh #{getbgesthost general}
nbgeneral nbjob run JOBCOMMAND -log $MT_LINKTREE/$MT_TARGET/$MT_RUNNAME.$MT_TESTNAME-$MT_ITEM_PATH.lgo
[hosts]
general cubian xena
[launchers]
envsetup general
xor/%/n 4C16G
% nbgeneral
[jobtools]
launcher bsub
# if defined and not "no" flexi-launcher will bypass launcher unless there is no
# match.
flexi-launcher yes

Debugging Tricks
----------------
Examining The Environment
~~~~~~~~~~~~~~~~~~~~~~~~~
During Config File Processing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It is often helpful to know the content of variables in various
contexts as Megatest does the actions needed to run your tests. A handy technique is to force the startup of an xterm in the context being examined.

Debugging Tricks
----------------
Examining The Environment
~~~~~~~~~~~~~~~~~~~~~~~~~
Test Control Panel - xterm
^^^^^^^^^^^^^^^^^^^^^^^^^^
From the dashboard click on a test PASS/FAIL button. This brings up a test control panel. Aproximately near the center left of the
window there is a button "Start Xterm". Push this to get an xterm with the full context and environment loaded for that test. You can run
scripts or ezsteps by copying from the testconfig (hint, load up the testconfig in a separate gvim or emacs window). This is the easiest way
to debug your tests.
