public void clearUserModules()

Description copied from interface: DataHub

Removes user's modules from the modules db

Specified by:

clearUserModules in interface DataHub

clearUserModules

public void clearUserModules(java.util.List<java.lang.String> resourceNamesToNotDelete)

Parameters:

resourceNamesToNotDelete - optional list of names of resources that should not be deleted; can be null; introduced for the sake of DHF tests so that marklogic-unit-test will not be deleted

clearUserArtifacts

public void clearUserArtifacts()

buildListOfCommands

public java.util.List<com.marklogic.appdeployer.command.Command> buildListOfCommands()

getSecurityCommandList

public java.util.List<com.marklogic.appdeployer.command.Command> getSecurityCommandList()

runPreInstallCheck

public java.util.Map<java.lang.String,java.lang.Object> runPreInstallCheck()

Description copied from interface: DataHub

Runs the pre-install check for the datahub populating the object with variables necessary to perform the install. This is used for running install. Must be run as a user with sufficient privileges to install a data hub.

Specified by:

runPreInstallCheck in interface DataHub

Returns:

- a hashmap of the results of the preinstall check

runPreInstallCheck

protected java.util.Map<java.lang.String,java.lang.Object> runPreInstallCheck(com.marklogic.mgmt.resource.appservers.ServerManager serverManager)

This overloaded version was added to facilitate mock testing - i.e. to be able to mock which ports are available.

Parameters:

serverManager -

Returns:

install

public void install()

Installs the data hub configuration and server-side config files into MarkLogic

Specified by:

install in interface DataHub

disableSomeCmaUsage

protected void disableSomeCmaUsage(com.marklogic.appdeployer.AppConfig appConfig)

Turns off CMA for some resources that have bbugs in ML 9.0-7/8.

Parameters:

appConfig -

updateIndexes

public void updateIndexes()

Note that this differs from how "mlUpdateIndexes" works in ml-gradle. This is not stripping out any "non-index" properties from each payload - it's just updating every database. This does however disable forest creation which speeds up the process so that the only calls made are to update the databases.

Specified by:

updateIndexes in interface DataHub

buildPatternForDatabasesToUpdateIndexesFor

protected java.util.regex.Pattern buildPatternForDatabasesToUpdateIndexesFor()

In a provisioned environment, only the databases defined by this pattern can be updated.

Returns:

database name pattern

buildCommandsForDeployingToReplica

public java.util.List<com.marklogic.appdeployer.command.Command> buildCommandsForDeployingToReplica()

Returns:

a list of commands that equate to what a full deployment will run, minus any commands that can write to any of the 8 DHF databases (staging, final, jobs, modules, and then the 4 triggers and schemas databases)

buildCommandMap

public java.util.Map<java.lang.String,java.util.List<com.marklogic.appdeployer.command.Command>> buildCommandMap()

Returns:

a map of command groups. The initial map is based on what ml-app-deployer constructs, and then modifications are made to many of the groups based on DHF requirements.

isSafeToInstall

public boolean isSafeToInstall()

Description copied from interface: DataHub

Checks to make sure all the versions and database in a valid configuration with version check Must be run as a user with sufficient privileges to install a data hub.

Specified by:

isSafeToInstall in interface DataHub

Returns:

boolean - if not, returns false, if safe to proceed ahead returns true

isPortInUse

public boolean isPortInUse(com.marklogic.hub.DatabaseKind kind)

Description copied from interface: DataHub

Checks to see if the port is in use

Specified by:

isPortInUse in interface DataHub

Parameters:

kind - - the DatabaseKind enum value (ex STAGING or JOB)

Returns:

true if the port is in use, false if it is not

getPortInUseBy

public java.lang.String getPortInUseBy(com.marklogic.hub.DatabaseKind kind)

Description copied from interface: DataHub

Returns name of what is using the port

Specified by:

getPortInUseBy in interface DataHub

Parameters:

kind - - the DatabaseKind enum value (ex STAGING or JOB)

Returns:

name of who using the port

isServerVersionOk

public boolean isServerVersionOk()

Description copied from interface: DataHub

Checks to see if the datahub and server versions are compatible

Specified by:

isServerVersionOk in interface DataHub

Returns:

true if the server version matches, false if it does not

getServerVersion

public java.lang.String getServerVersion()

Description copied from interface: DataHub

Returns the string presentation of the server version, eg: "9.03-1"

Specified by:

getServerVersion in interface DataHub

Returns:

server version as a string, eg: "9.03-1"

upgradeHub

public boolean upgradeHub()

Description copied from interface: DataHub

Upgrades the installed datahub on the server to this version of the DataHub Must be run as a user with sufficient privileges to install a data hub.

Specified by:

upgradeHub in interface DataHub

Returns:

true or false based on success of the upgrade

verifyLocalProjectIs430OrGreater

protected void verifyLocalProjectIs430OrGreater()

Per DHFPROD-4912, instead of depending on mlDHFVersion, this logic takes advantage of the fact that the hub-internal-config triggers - including ml-dh-entity-create.json - had their permissions modified in the 4.3.0 release.

prepareProjectBeforeUpgrading

protected void prepareProjectBeforeUpgrading(HubProject hubProject,
                                             java.lang.String newDataHubVersion)
                                      throws java.io.IOException

The expectation is that a user has upgraded build.gradle to use a newer version of DHF but has not yet updated mlDHFVersion in gradle.properties. Thus, the value of mlDHFVersion is expected to be passed in here so that the backup path of hub-internal-config has the current version of DHF in its name.

Parameters:

hubProject -

newDataHubVersion -

Throws:

java.io.IOException

setHubConfig

public void setHubConfig(HubConfigImpl hubConfig)

getHubConfig

public HubConfig getHubConfig()

setVersions

public void setVersions(Versions versions)

clearUserData

public void clearUserData()

Clear "user data", which is anything that's not a user or hub artifact. Depends on the ability to clear the staging, final, and job databases. An error will be thrown if a user doesn't have the privilege to perform any of those operations. This is intentionally not exposed in the DataHub interface, as there's no use case yet for a client of this library to perform this operation. It can instead be accessed via Hub Central and Gradle.

clearUserSchemas

public void clearUserSchemas()
