resources to make writing a suite of tests and tasks for implementing
continuous build for software, design engineering or process control (via
owlfs for example) without being specialized for any specific problem

of a test or task. In most cases megatest is best used in conjunction with
logpro or a similar tool to parse, analyze and decide on the test outcome.</p></div>

tool, flexible enough to meet the needs of any team doing continuous
integrating and or running a complex suite of tests for release
qualification.

Megatest Design Philosophy
--------------------------

Megatest is a distributed system intended to provide the minimum needed
resources to make writing a suite of tests and tasks for implementing
continuous build for software, design engineering or process control (via
owlfs for example) without being specialized for any specific problem
space. Megatest in of itself does not know what constitutes a PASS or FAIL
of a test or task. In most cases megatest is best used in conjunction with
logpro or a similar tool to parse, analyze and decide on the test outcome.


 * Self-checking -Repeatable strive for directed or self-checking test
   as opposed to delta based tests

 * Traceable - environment variables, host OS and other possibly influential
   variables are captured and kept recorded.

[a/2/b]
VAR1 VAL2

Can use either wildcard of "%" or a regular expression:

Disk Space Checks
^^^^^^^^^^^^^^^^^

Some parameters you can put in the [setup] section of megatest.config:

[triggers]
COMPLETED/ xterm -e bash -s -- 
-----------------

NOTE: There is a trailing space after the --

There are a number of environment variables available to the trigger script
but since triggers can be called in various contexts not all variables are
available at all times. The trigger script should check for the variable and
fail gracefully if it doesn't exist.

|Variable             | Purpose

| MT_TEST_NAME        | The name of this test
| MT_ITEM_INFO        | The variable and values for the test item
| MT_MEGATEST         | Which Megatest binary is being used by this area
| MT_TARGET           | The target variable values, separated by '/'
| MT_LINKTREE         | The base of the link tree where all run tests can be found
| MT_ITEMPATH         | The values of the item path variables, separated by '/'
| MT_RUNNAME          | The name of the run

Override the Toplevel HTML File
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Megatest generates a simple html file summary for top level tests of
iterated tests. The generation can be overridden. NOTE: the output of

Road Map
--------

Note 1: This road-map is still evolving and subject to change without notice.

Architecture Refactor
~~~~~~~~~~~~~~~~~~~~~

Goals
^^^^^

. Reduce load on the file system. Sqlite3 files on network filesystem can be
  a burden. [green]#[DONE]#
. Reduce number of servers and frequency of start/stop. This is mostly an
  issue of clutter but also a reduction in "moving parts". [green]#[DONE]#
. Coalesce activities to a single home host where possible. Give the user
  feedback that they have started the dashboard on a host other than the
  home host. [green]#[DONE]#
. Reduce number of processes involved in managing running tests.

Changes Needed
^^^^^^^^^^^^^^

. ACID compliant db will be on /tmp and synced to megatest.db with a five
  second max delay. [green]#[DONE]#
. Read/writes to db for processes on homehost will go direct to /tmp
  megatest.db file. [green]#[DONE]#
. Read/wites fron non-homehost processes will go through one server. Bulk
  reads (e.g. for dashboard or list-runs) will be cached on the current host
  in /tmp and synced from the home megatest.db in the testsuite area. [green]#[DONE]#
. Db syncs rely on the target db file timestame minus some margin. [green]#[DONE]#
. Since bulk reads do not use the server we can switch to simple RPC for the
  network transport. [green]#[DONE]#
. Test running manager process extended to manage multiple running tests.

Current Items
~~~~~~~~~~~~~

ww05 - migrate to inmem-db
^^^^^^^^^^^^^^^^^^^^^^^^^^

. Switch to inmem db with fast sync to on disk db's [green]#[DONE]#
. Server polls tasks table for next action
.. Task table used for tracking runner process [red]#[Replaced by mtutil]#
.. Task table used for jobs to run [red]#[Replaced by mtutil]#
.. Task table used for queueing runner actions (remove runs,
   cleanRunExecute, etc)  [red]#[Replaced by mtutil#]
