TODO
====

WW38
. Add test_rundat to no-sync ==> correction, put in <testdir>/.meta/test-run.dat
. Add STATE/STATUS transitions to .meta/test-run.dat or similar
. Swizzle update-test-rundat to operate on no-sync
. Swizzle update-run-duration, -uname-host and cpuload-diskfree to no-sync
. On state/status change update tests table with duration

WW15
. fill newview matrix with data, filter pipeline gui elements
. improve [script], especially indent handling

WW16
. split db into megatest.db (runs etc.) db/<something>.db
. release basic newview implementation

Ezsteps
~~~~~~~

Ezsteps is the recommended way to implement tests and automation in
Megatest.

NOTE: Each ezstep must be a single line. Use the [scripts] mechanism
to create multiline scripts (see example below).

.Example ezsteps with logpro rules
-----------------
[ezsteps]
lookittmp   ls /tmp

[logpro]
lookittmp ;; Note: config file format supports multi-line entries where leading whitespace is removed from each line
  ;;     a blank line indicates the end of the block of text 
  (expect:required in "LogFileBody" > 0 "A file name that should never exist!" #/This is a awfully stupid file name that should never be found in the temp dir/)

-----------------

Automatic environment propagation with Ezsteps
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# if your upstream file is csh you can force csh like this
# if your upstream is bash 
loadenv     source $REF/ourenviron.sh


Turn on ezpropvars and environment variables will be propagated from
step to step. Use this to source script files that modify the
envionment where the modifications are needed in subsequent steps.

NOTE: aliases and variables with strange whitespace or characters will
not propagate correctly. Put in a ticket on the
http://www.kiatoa.com/fossils/megatest site if you need support for a
specific strange character combination.

.Turn on auto propagate for bash
---------------------------
[setup]
ezpropvars sh
---------------------------

.Write your ezsteps. The loadenv.csh step will use /bin/csh as its shell, other steps will use bash.
---------------------------
[ezsteps]
loadenv.csh source $REF/ourenviron.csh
compile make
install make install
---------------------------

Bash and csh are supported. You can override the shell binary location
from the default /bin/bash and /bin/csh if needed.

.Turn on auto propagate for csh
---------------------------
[setup]
ezpropvars csh /bin/csh
---------------------------

.Example of auto propagation using extensions
---------------------------
[ezsteps]
step1.sh export SOMEVAR=$(ps -def | wc -l);ls /tmp
# The next step will get the value of $SOMEVAR from step1.sh
step2.sh echo $SOMEVAR
---------------------------

.Example of multi-line script
---------------------------
[scripts]
tarresults tar cfvz $DEST/srcdir1.tar.gz srcdir1
  tar cfvz $DEST/srcdir2.tar.gz srcdir2

[setup]
ezpropvars sh

[ezsteps]
step1 DEST=/tmp/targz;source tarresults
---------------------------

The above example will result in files; tarresults and ez_step1 being
created in the test dir.

Launching and managing runs
  -run                    : run all tests or as specified by -testpatt
  -remove-runs            : remove the data for a run, requires -runname and -testpatt
                            Optionally use :state and :status, use -keep-records to remove only
                            the run data. Use -kill-wait to override the 10 second
                            per test wait after kill delay (e.g. -kill-wait 0). 

  -sync-to-megatest.db    : pull data from cache files in /tmp/$USER to megatest.db
  -sync-to dest           : sync to new postgresql central style database
  -update-meta            : update the tests metadata for all tests
  -setvars VAR1=val1,VAR2=val2 : Add environment variables to a run NB// these are
                                 overwritten by values set in config files.
  -server -|hostname      : start the server (reduces contention on megatest.db), use
                            - to automatically figure out hostname
  -adjutant host-type     : start the server/adjutant with given host-type
                            use 0,0 to auto use full machine
  -transport http|rpc     : use http or rpc for transport (default is http) 
  -log logfile            : send stdout and stderr to logfile
  -list-servers           : list the servers 
  -kill-servers           : kill all servers
