[OpenMadrigal-developers] Madrigal patch for SRI

[William Rideout]

Angela,

As promised, here's the patch that should make your global search 
function work correctly.  Here's how to install it:

1.  Copy the attached file SRI_patch.tar to $MADROOT
2.  cd $MADROOT
3.  tar -xf SRI_patch.tar
4.  make -f Makefile.gnu madrec
5.  make -f Makefile.gnu binary
6.  cd $MADROOT/source/madpy
7.  /usr/bin/python setup.py install

This should make the global search work correctly.  Please email me when 
its done so I can check.

Technical discussion:

There were actually two problems that I corrected:

1.  The python method os.spawnlp uses the $PATH variable to execute a 
process even when its passed a full path to the executable (which I 
didn't realize).  So even though I was passing it "/usr/bin/python", it 
was running a different version of python when it was kicking off a 
background job to produce the global search report.  This lead to the 
"madrigal.metadata not found" error.  I changed os.spawnlp to os.spawnl, 
which will not try to use the $PATH variable, but instead insists on a 
full path to the executable.  This was changed in the file report.py, 
and is the reason you ran /usr/bin/python setup.py install in step 7.

2. Cycle marks:  We assumed cycle marks (Cedar parameter 95) in a file 
always would go in sequence, and I used to abort if I found an out of 
order cycle mark.  SRI clearly uses this parameter differently, so I 
changed the C engine to simply ignore out of order cycle marks.  This is 
why you rebuilt and re-installed the C madrec library in steps 4 and 5.

Both these changes have been checked into CVS and will be part of any 
future release, so they are not SRI specific.
