Class VersionPrms

java.lang.Object

hydra.BasePrms

hydra.VersionPrms

public class VersionPrms
extends BasePrms

A class used to store keys for version configuration settings. The settings are used to create instances of VersionDescription. These can be referenced by instances of ClientDescription as configured using ClientPrms-versionNames.

The number of description instances is gated by names. For other parameters, if fewer values than names are given, the remaining instances will use the last value in the list. See $JTESTS/hydra/hydra.txt for more details.

Unused parameters default to null, except where noted. This uses the default, except where noted.

Values and fields of a parameter can be set to BasePrms.DEFAULT, except where noted. This uses the default, except where noted.

Values and fields of a parameter can use oneof, range, or robing except where noted, but each description created will use a fixed value chosen at test configuration time. Use as a task attribute is illegal.

Field Detail

SUPPORTED_VERSIONS

public static final String[] SUPPORTED_VERSIONS

Supported values for version.

names

public static Long names

(String(s)) Logical names of the version descriptions. Each name must be unique. Defaults to null. Not for use with oneof, range, or robing.

gemfireHome

public static Long gemfireHome

(String(s)) GemFire home directories used by hydra client VMs configured to use this description. If supplied, values must be absolute paths to the product directory.

Defaults to null if version is not set, otherwise defaults to the release for the version found in "/export/gcm/where/gemfire/releases". The release location can be modified by passing the system property RELEASE_DIR to BatteryTest or MasterController.

version

public static Long version

(String(s)) Version of the GemFire product used by hydra client VMs configured to use this description. Legal values are given in SUPPORTED_VERSIONS. The version must be consistent with the corresponding value in gemfireHome. The version is used to prepend hydra conversion code and version-specific test code in $JTESTS/../../tests/classes to the client classpath. Clients are configured to use version description using ClientPrms.versionNames.

versions

public static Long versions

(Comma-separated lists of String(s)) Versions of the GemFire product used by hydra client VMs configured to use this description. Legal values are given in SUPPORTED_VERSIONS. Overrides version and ignores gemfireHome, so the version is always the one found in /export/gcm/where/gemfireXD/releases.

Hydra starts a JVM that has a configured list of versions at the first version given. Each time the JVM is restarted, it is brought back at the next version in its list. Once the last version is reached, the JVM stays at that version for all further restarts.

This feature was put in place for tests that do rolling upgrades.
