Test Case Description: Program designed to:
|
||||
Pre and Post Conditions Existence of at least 2 files in the present directory (see
below). |
||||
Input/Output Specifications ·
Possibility of changing the following two
environment variables before running, by editing the file pool.env: 1
POOL_OUTMSG_LEVEL: Only
program monitoring information with a SEAL message level greater than the
value of this variable will printed to the screen. Possible options
are: ·
-1 => seal::MSG::NIL ·
0 => seal::MSG::VERBOSE ·
1 => seal::MSG::DEBUG ·
2 => seal::MSG::INFO ·
3 => seal::MSG::WARNING ·
4 => seal::MSG::ERROR ·
5 => seal::MSG::FATAL The default value of POOL_OUTMSG_LEVEL is 2 2
POOL_MYSQL_CONNECT: This is the location of the MySQL database being used. It is useful to change this
variable to a local location if, for instance, network speeds are of
significant concern. The default value of POOL_MYSQL_CONNECT is "mysql://regrTester:rT2003@lxshare070d.cern.ch/regression"
·
Existence of a file with suffix pool
containing the collection’s persistent data. ·
Existence of a file called PoolFileCatalog.xml containing database file
identification information. ·
Existence of a local file (e.g. in the
case of a Root collection) or a database table (e.g. in the case of a MySQL collection) containing the collection of data
object references and associated meta data. ·
Creation of a file (called Test_Read.log by default) containing a detailed list of
the performance data. |

Test Procedure
% cd $MyPoolArea/src % cvs co –r
POOL_<latest release tag> Tests/Collection_ExplicitReadPerformance
% scram build :
% cd Tests/Collection_ExplicitReadPerformance
% eval `scram runtime –csh`
% eval `scram runtime –csh
pool.env`
% rehash
% test_Collection_ExplicitWritePerformance
<collection name prefix> <number of events> <number of
attributes> <collection type (MySQL or
Root)> [Task to perform on query results: 0=empty loop, 1=type check,
2=create Ref<T>, 3=dereference Ref<T>, 4=read attribute list,
5=convert Ref<T> to string DEFAULT=0] [name of performance data output
file DEFAULT = Test_Read.log] [selection query
DEFAULT = “”] [iterator options: FetchOne (use cache) or FetchAll
(do not use cache) DEFAULT = FetchAll] [benchmark
options: attribute_list_constructor (create
attribute list from iterator for every event) or
pause (wait for a key before doing the benchmark) DEFAULT = “”] Note: To see a screen printout of the above command line options
simply type test_Collection_ExplicitReadPerformance
with no options. Note: Any optional argument may be masked out with the – char. |
||||
Expected results The following file will be produced:
1. Total number of events and attributes of collection used 2. Number of events that satisfy the query. 3. Time (in milliseconds) to create the iterator
for events satisfying the query. 4. Time (in milliseconds) to iterate over the events satisfying
the query. 5. Total time (in milliseconds). |
