The stress errors are due to database lookups on manifests and profiles
that have been deleted during 'installadm list -p/-m'. For example, in
AI_database.py:getNames(), the number of names (manifest or profile
entries) is counted, then database queries are launched one at a time (a
memory usage limitation feature for very large queries), which
introduces a window during which the entry can be deleted, and the
corresponding query fails.
The solution is to add checks that the rows exist in the query output
before referencing them.
Stress-tested with this script and variations, looping, using 5
different profiles at a time, then launching the same script multiple
times to compound the contention:
import sys
import subprocess
mysys = sys.argv[1] # profile
mysvc = '167nightly'
mycp = ['installadm', 'create-profile', '-p', mysys, '-n', mysvc, '-f',
mysys]
myls = ['installadm', 'list', '-p', '-n', mysvc]
mydp = ['installadm', 'delete-profile', '-p', mysys, '-n', mysvc]
subprocess.call(mycp)
subprocess.call(myls)
subprocess.call(mydp)
Calling code was checked for compatibility.
Related pyunit tests pass.
