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
|
|
|
|
The library is built using the top level build-test-failure-handler target and
|
|
is automatically included in the test image and picked up by hotspot and jdk
|
|
test makefiles.
|
|
|
|
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.
