DESCRIPTION
The purpose of this library is gathering diagnostic information on test
failures and timeouts. The library runs platform specific tools, which are
configured in the way described below. The collected data will be available
in HTML format next to JTR files.
The library uses JTHarness Observer and jtreg TimeoutHandler extensions points.
DEPENDENCES
The library requires jtreg 4b13+ and JDK 7+.
BUILDING
To build a library, one should simply run make with 'JTREG_HOME' and
'JAVA_HOME' environment variables set. 'JAVA_HOME' should contain path to JDK,
'JTREG_HOME' -- path to jtreg.
'image/lib/jtregFailureHandler.jar' is created on successful build.
CONFIGURATION
Properties files are used to configure the library. They define which actions
to be performed in case of individual test failure or timeout. Each platform
family uses its own property file (named '<platform>.properties'). For platform
independent actions, 'common.properties' is used.
Actions to be performed on each failure are listed in 'environment' property.
Extra actions for timeouts are listed in 'onTimeout'.
Each action is defined via the following parameters:
- 'javaOnly' -- run the action only for java applications, false by default
- 'app' -- an application to run, mandatory parameter
- 'args' -- application command line arguments, none by default
- 'params' -- a structure which defines how an application should be run,
described below
Actions listed in 'onTimeout' are "patterned" actions. Besides the parameters
listed above, they also have 'pattern' parameter -- a string which will be
replaced by PID in 'args' parameter before action execution.
'params' structure has the following parameters:
- repeat -- how many times an action will be run, 1 by default
- pause -- delay in ms between iterations, 500 by default
- timeout -- time limitation for iteration in ms, 20 000 by default
- stopOnError -- if true, an action will be interrupted after the first error,
false by default
From '<platform>.properties', the library reads the following parameters
- 'config.execSuffix' -- a suffix for all binary application file names
- 'config.getChildren' -- a "patterned" action used to get the list of all
children
For simplicity we use parameter values inheritance. This means that we are
looking for the most specified parameter value. If we do not find it, we are
trying to find less specific value by reducing prefix.
For example, if properties contains 'p1=A', 'a.p1=B', 'a.b.p1=C', then
parameter 'p1' will be:
- 'C' for 'a.b.c'
- 'B' for 'a.c'
- 'A' for 'b.c'
RUNNING
To enable the library in jtreg, the following options should be set:
- '-timeoutHandlerDir' points to the built jar ('jtregFailureHandler.jar')
- '-observerDir' points to the built jar
- '-timeoutHandler' equals to jdk.test.failurehandler.jtreg.GatherProcessInfoTimeoutHandler
- '-observer' equals to jdk.test.failurehandler.jtreg.GatherDiagnosticInfoObserver
In case of environment issues during an action execution, such as missing
application, hung application, lack of disk space, etc, the corresponding
warning appears and the library proceeds to next action.
EXAMPLES
$ ${JTREG_HOME}/bin/jtreg -jdk:${JAVA_HOME} \
-timeoutHandlerDir:./image/lib/jtregFailureHandler.jar \
-observerDir:./image/lib/jtregFailureHandler.jar \
-timeoutHandler:jdk.test.failurehandler.jtreg.GatherProcessInfoTimeoutHandler\
-observer:jdk.test.failurehandler.jtreg.GatherDiagnosticInfoObserver \
