## Class SVNAdminClient

- java.lang.Object
- - org.tmatesoft.svn.core.wc.admin.SVNAdminBasicClient
  - - org.tmatesoft.svn.core.wc.admin.SVNAdminClient

All Implemented Interfaces:
  ISVNCanceller, ISVNEventHandler

    public class SVNAdminClient
    extends SVNAdminBasicClient

The SVNAdminClient class provides methods that brings repository-side functionality and repository synchronizing features.

Repository administrative methods are analogues of the corresponding commands of the native Subversion 'svnadmin' utility, while repository synchronizing methods are the ones for the 'svnsync' utility.

Here's a list of the SVNAdminClient's methods matched against corresponing commands of the Subversion svnsync and svnadmin command-line utilities:

SVNKit | Subversion
doInitialize() | 'svnsync initialize'
doSynchronize() | 'svnsync synchronize'
doInfo() | 'svnsync info'
doCopyRevisionProperties() | 'svnsync copy-revprops'
doDump() | 'svnadmin dump'
doListTransactions() | 'svnadmin lstxns'
doLoad() | 'svnadmin load'
doRemoveTransactions() | 'svnadmin rmtxns'
doVerify() | 'svnadmin verify'
doPack() | 'svnadmin pack'

                                long endRevision)
                                  throws SVNException

Copies revision properties from the source repository starting at `startRevision` and up to `endRevision` to corresponding revisions of the destination repository represented by `toURL`.

This method is equivalent to the command 'copy-revprops' of the native Subversion svnsync utility. Note that the destination repository given as `toURL` must be synchronized with a source repository. Please, see `doInitialize(SVNURL, SVNURL)`} how to initialize such a synchronization.

If the caller has `provided` an event handler, the handler will receive an `SVNAdminEvent` with the `SVNAdminEventAction.REVISION_PROPERTIES_COPIED` action when the properties get copied.

Parameters:
  `toURL` - a url to the destination repository which must be synchronized with another repository
  `startRevision` - start revision
  `endRevision` - end revision
Throws:
  `SVNException` - in the following cases:
  exception with `SVNErrorCode.IO_ERROR` error code - if any of revisions between `startRevision` and `endRevision` inclusively was not synchronized yet
Since:
  1.2.0, new in Subversion 1.5.0

#### doInitialize

    public void doInitialize(SVNURL fromURL,
                    SVNURL toURL)
                      throws SVNException

Initializes synchronization between source and target repositories.

This method is equivalent to the command 'initialize' ('init') of the native Subversion svnsync utility. Initialization places information of a source repository to a destination one (setting special revision properties in revision 0) as well as copies all revision props from revision 0 of the source repository to revision 0 of the destination one.

Parameters:
  `fromURL` - a source repository url
  `toURL` - a destination repository url
Throws:
  `SVNException` - in the following cases:
  exception with `SVNErrorCode.IO_ERROR` error code - if either the target repository's last revision is different from `0`, or no `SVNRevisionProperty.FROM_URL` property value found in the target repository
  exception with `SVNErrorCode.RA_PARTIAL_REPLAY_NOT_SUPPORTED` error code - if the source repository does not support partial replay
Since:
  1.1, new in Subversion 1.4

#### doInfo

    public SVNSyncInfo doInfo(SVNURL toURL)
                       throws SVNException

Returns information about the synchronization repository located at `toURL`.

Parameters:
  `toURL` - destination repository url
Returns:
  synchronization information
Throws:
  `SVNException`
Since:
  1.3, SVN 1.6

#### doPack

    public void doPack(java.io.File repositoryRoot)
                throws SVNException

Compacts a repository into a more efficient storage model.

Compacting does not occur if there are no full shards. Also compacting does not work on pre-1.6 repositories.

Parameters:
  `repositoryRoot` - root of the repository to pack
Throws:
  `SVNException`
Since:
  1.3, SVN 1.6

#### doCompleteSynchronize

    public void doCompleteSynchronize(SVNURL fromURL,
                             SVNURL toURL)
                               throws SVNException

Completely synchronizes two repositories.

This method initializes the destination repository and then copies all revision changes (including revision properties) from the given source repository to the destination one. First it tries to use synchronization features similar to the native Subversion 'svnsync' capabilities. But if a server does not support `replay` functionality, SVNKit uses its own repository replication feature (see `SVNRepositoryReplicator`})

Parameters:
  `fromURL` - a url of a repository to copy from
  `toURL` - a destination repository url
Throws:
  `SVNException`
Since:
  1.1

#### doSynchronize

    public void doSynchronize(SVNURL toURL)
                       throws SVNException

Synchronizes the repository at the given url.

Synchronization means copying revision changes and revision properties from the source repository (that the destination one is synchronized with) to the destination one starting at the last merged revision. This method is equivalent to the command 'synchronize' ('sync') of the native Subversion svnsync utility.

Parameters:
  `toURL` - a destination repository url
Throws:
  `SVNException`
Since:
  1.1, new in Subversion 1.4

#### doListLocks

    public void doListLocks(java.io.File repositoryRoot)
                     throws SVNException

Walks through the repository tree found under `repositoryRoot` and reports all found locks via calls to the caller's `ISVNAdminEventHandler` handler implementation.

On each locked path found this method dispatches an `SVNAdminEventAction.LOCK_LISTED` `event` to the caller's handler providing the `lock information`.

Parameters:
  `repositoryRoot` - repository root location
Throws:
  `SVNException`
Since:
  1.2.0, SVN 1.5.0

#### doRemoveLocks

    public void doRemoveLocks(java.io.File repositoryRoot,
                     java.lang.String[] paths)
                       throws SVNException

Removes locks from the specified `paths` in the repository found under `repositoryRoot`.

If any path of the `paths` is not locked, then an `event` with the `SVNAdminEventAction.NOT_LOCKED` action is dispatched to the caller's `ISVNAdminEventHandler` handler.

If, on the contrary, a path is locked, it is unlocked and an event with the `SVNAdminEventAction.UNLOCKED` action is dispatched to the caller's handler providing the `lock information`.

If some error occurs while unlocking, an event with the `SVNAdminEventAction.UNLOCK_FAILED` action is dispatched to the caller's handler providing the `error description`.

Parameters:
  `repositoryRoot` - repository root location
  `paths` - paths to unlock
Throws:
  `SVNException`
Since:
  1.2.0, SVN 1.5.0

#### doListTransactions

    public void doListTransactions(java.io.File repositoryRoot)
                            throws SVNException

Lists all uncommitted transactions. On each uncommetted transaction found this method fires an `SVNAdminEvent` with action set to `SVNAdminEventAction.TRANSACTION_LISTED` to the registered `ISVNAdminEventHandler` (if any). To register your ISVNAdminEventHandler pass it to `setEventHandler(ISVNEventHandler)`. For this operation the following information can be retrieved out of `SVNAdminEvent`:

- transaction name - use `SVNAdminEvent.getTxnName()` to get it
- transaction directory - use `SVNAdminEvent.getTxnDir()` to get it

Parameters:
  `repositoryRoot` - a repository root directory path
Throws:
  `SVNException`
Since:
  1.1.1

#### doRemoveTransactions

    public void doRemoveTransactions(java.io.File repositoryRoot,
                            java.lang.String[] transactions)
                              throws SVNException

Removes the specified outstanding transactions from a repository. On each transaction removed this method fires an `SVNAdminEvent` with action set to `SVNAdminEventAction.TRANSACTION_REMOVED` to the registered `ISVNAdminEventHandler` (if any). To register your ISVNAdminEventHandler pass it to `setEventHandler(ISVNEventHandler)`. For this operation the following information can be retrieved out of `SVNAdminEvent`:

- transaction name - use `SVNAdminEvent.getTxnName()` to get it
- transaction directory - use `SVNAdminEvent.getTxnDir()` to get it

Parameters:
  `repositoryRoot` - a repository root directory path
  `transactions` - an array with transaction names
Throws:
  `SVNException`
Since:
  1.1.1

#### doVerify

    public void doVerify(java.io.File repositoryRoot)
                  throws SVNException

Verifies the data stored in the repository. This method uses the dump implementation (non incremental, beginning with revision 0, ending at the latest one) passing a dummy output stream to it. This allows to check the integrity of the repository data.

This is identical to `doVerify(repositoryRoot, SVNRevision.create(0), SVNRevision.HEAD)`.

Parameters:
  `repositoryRoot` - a repository root directory path
Throws:
  `SVNException` - verification failed - a repository may be corrupted
Since:
  1.1.1

#### doVerify

    public void doVerify(java.io.File repositoryRoot,
                SVNRevision startRevision,
                SVNRevision endRevision)
                  throws SVNException

Verifies repository contents found under `repositoryRoot` starting at `startRevision` and up to `endRevision`. This method uses the dump implementation (non incremental) passing a dummy output stream to it. This allows to check the integrity of the repository data.

If `startRevision` is `invalid`, it defaults to `0`. If `endRevision` is `invalid`, it defaults to the HEAD revision.

Parameters:
  `repositoryRoot` - a repository root directory path
  `startRevision` - revision to start verification at
  `endRevision` - revision to stop verification at
Throws:
  `SVNException` - verification failed - a repository may be corrupted
Since:

#### doDump

    public void doDump(java.io.File repositoryRoot,
              java.io.OutputStream dumpStream,
              SVNRevision startRevision,
              SVNRevision endRevision,
              boolean isIncremental,
              boolean useDeltas)
                throws SVNException

Dumps contents of the repository to the provided output stream in a 'dumpfile' portable format.

On each revision dumped this method fires an `SVNAdminEvent` with action set to `SVNAdminEventAction.REVISION_DUMPED` to the registered `ISVNAdminEventHandler` (if any). To register your ISVNAdminEventHandler pass it to `setEventHandler(ISVNEventHandler)`. For this operation the following information can be retrieved out of `SVNAdminEvent`:

- dumped revision - use `SVNAdminEvent.getRevision()` to get it

Parameters:
  `repositoryRoot` - a repository root directory path
  `dumpStream` - an output stream to write dumped contents to
  `startRevision` - the first revision to start dumping from
  `endRevision` - the last revision to end dumping at
  `isIncremental` - if true then the first revision dumped will be a diff against the previous revision; otherwise the first revision is a fulltext.
  `useDeltas` - if true deltas will be written instead of fulltexts
Throws:
  `SVNException`
Since:
  1.1.1

#### doLoad

    public void doLoad(java.io.File repositoryRoot,
              java.io.InputStream dumpStream)
                throws SVNException

Reads the provided dump stream committing new revisions to a repository.

On each revision loaded this method fires an `SVNAdminEvent` with action set to `SVNAdminEventAction.REVISION_LOADED` to the registered `ISVNAdminEventHandler` (if any). To register your ISVNAdminEventHandler pass it to `setEventHandler(ISVNEventHandler)`. For this operation the following information can be retrieved out of `SVNAdminEvent`:

- original revision - use `SVNAdminEvent.getOriginalRevision()` to get it
- new committed revision - use `SVNAdminEvent.getRevision()` to get it

A call to this method is equivalent to `doLoad(repositoryRoot, dumpStream, false, false, SVNUUIDAction.DEFAULT, null)`.

#### doLoad

    public void doLoad(java.io.File repositoryRoot,
              java.io.InputStream dumpStream,
              boolean usePreCommitHook,
              boolean usePostCommitHook,
              SVNUUIDAction uuidAction,
              java.lang.String parentDir)
                throws SVNException

Reads the provided dump stream committing new revisions to a repository.

On each revision loaded this method fires an `SVNAdminEvent` with action set to `SVNAdminEventAction.REVISION_LOADED` to the registered `ISVNAdminEventHandler` (if any). To register your ISVNAdminEventHandler pass it to `setEventHandler(ISVNEventHandler)`. For this operation the following information can be retrieved out of `SVNAdminEvent`:

- original revision - use `SVNAdminEvent.getOriginalRevision()` to get it
- new committed revision - use `SVNAdminEvent.getRevision()` to get it

Parameters:
  `repositoryRoot` - the root directory path of the repository where new revisions will be committed
  `dumpStream` - stream with dumped contents of a repository
  `usePreCommitHook` - if true then calls a pre-commit hook before committing
  `usePostCommitHook` - if true then calls a post-commit hook after committing
  `uuidAction` - one of the three possible ways to treat uuids
  `parentDir` - if not null then loads at this directory in the repository
Throws:
  `SVNException`
Since:
  1.1.1

#### doRecover

    public void doRecover(java.io.File repositoryRoot)
                   throws SVNException

Recovers the repository found under `repositoryRoot`. This method can recover only FSFS type repositories and is identical to the `'svnadmin recover'` command.

If the caller has `provided` an event handler, the handler will receive an `SVNAdminEvent` with the `SVNAdminEventAction.RECOVERY_STARTED` action before the recovery starts.

Parameters:
  `repositoryRoot` - repository root location
Throws:
  `SVNException`
Since:
  1.2.0, SVN 1.5.0

#### doUpgrade

    public void doUpgrade(java.io.File repositoryRoot)
                   throws SVNException

Upgrades the repository located at `repositoryRoot` to the latest supported schema version. This method is identical to the `'svnadmin upgrade'` command.

This functionality is provided as a convenience for repository administrators who wish to make use of new Subversion functionality without having to undertake a potentially costly full repository dump and load operation. As such, the upgrade performs only the minimum amount of work needed to accomplish this while still maintaining the integrity of the repository. It does not guarantee the most optimized repository state as a dump and subsequent load would.

If the caller has `provided` an event handler, the handler will receive an `SVNAdminEvent` with the `SVNAdminEventAction.UPGRADE` action before the upgrade starts.

Parameters:
  `repositoryRoot` - repository root location
Throws:
  `SVNException`
Since:
  1.2.0, SVN 1.5.0

#### doSetUUID

    public void doSetUUID(java.io.File repositoryRoot,
                 java.lang.String uuid)
                   throws SVNException

Resets the repository UUID with the provided `uuid` for the repository located at `repositoryRoot`. This method is identical to the `'svnadmin setuuid'` command.

If no `uuid` is specified, then `SVNKit` will generate a new one and will use it to reset the original UUID.

Parameters:
  `repositoryRoot` - repository root location
  `uuid` - new UUID to set
Throws:
  `SVNException` - exception with `SVNErrorCode.BAD_UUID` error code - if the `uuid` is malformed
Since:
  1.2.0, SVN 1.5.0

#### doHotCopy

    public void doHotCopy(java.io.File srcRepositoryRoot,
                 java.io.File newRepositoryRoot)
                   throws SVNException

Makes a hot copy of a repository located at `srcRepositoryRoot` to one located at `newRepositoryRoot`. This method is identical to the `'svnadmin hotcopy'` command.

Parameters:
  `srcRepositoryRoot` - repository to copy data from
  `newRepositoryRoot` - repository to copy data to
Throws:
  `SVNException`
Since:
  1.2.0, SVN 1.5.0

#### getYoungestRevision

    public long getYoungestRevision(java.io.File repositoryRoot)
                             throws SVNException

Returns the HEAD revision of the repository located at `repositoryRoot`.

Identical to the `'svnlook youngest'` svn command.

Parameters:
  `repositoryRoot` - repository root location
Returns:
  the last revision
Throws:
  `SVNException`
Since:
  1.2.0

#### doFilter

    public void doFilter(java.io.InputStream dumpStream,
                java.io.OutputStream resultDumpStream,
                boolean exclude,
                boolean renumberRevisions,
                boolean dropEmptyRevisions,
                boolean preserveRevisionProperties,
                java.util.Collection prefixes,
                boolean skipMissingMergeSources)
                  throws SVNException

Filters out nodes with or without the given `prefixes` from `dumpStream` to `resultDumpStream`. This method is similar to the functionality provided by the `'svndumpfilter'` utility.

If `exclude` is true then filters out nodes with `prefixes`, otherwise nodes without `prefixes`.

If the caller has `provided` an event handler, the handler will be called with different actions:

`SVNAdminEventAction.DUMP_FILTER_TOTAL_REVISIONS_DROPPED` - use `SVNAdminEvent.getDroppedRevisionsCount()` to retrieve the total number of dropped revisions.
`SVNAdminEventAction.DUMP_FILTER_DROPPED_RENUMBERED_REVISION` - is sent only when `renumberRevisions` is true and informs that an original revision (which is provided as `SVNAdminEvent.getRevision()`) was dropped.
`SVNAdminEventAction.DUMP_FILTER_RENUMBERED_REVISION` - is sent only when `renumberRevisions` is true and informs that the original revision (provided as `SVNAdminEvent.getOriginalRevision()`) was renumbered to `SVNAdminEvent.getRevision()`.
`SVNAdminEventAction.DUMP_FILTER_DROPPED_NODE` - says that `SVNAdminEvent.getPath()` was dropped.
`SVNAdminEventAction.DUMP_FILTER_TOTAL_NODES_DROPPED` - use `SVNAdminEvent.getDroppedNodesCount()` to retrieve the total number of dropped nodes.
`SVNAdminEventAction.DUMP_FILTER_REVISION_COMMITTED` - is sent to inform that the original revision `SVNAdminEvent.getOriginalRevision()` resulted in `SVNAdminEvent.getRevision()` in the output.
`SVNAdminEventAction.DUMP_FILTER_REVISION_SKIPPED` - is sent to inform that the original revision `SVNAdminEvent.getRevision()` is dropped (skipped).

Parameters:
  `dumpStream` - the input repository dump stream
  `resultDumpStream` - the resultant (filtered) dump stream
  `exclude` - whether to exclude or include paths with the specified `prefixes`
  `renumberRevisions` - if true, renumbers revisions left after filtering
  `dropEmptyRevisions` - if true, then removes revisions emptied by filtering
  `preserveRevisionProperties` - if true, then does not filter revision properties
  `prefixes` - prefixes of the path to filter
  `skipMissingMergeSources` - if true, then skips missig merge sources
Throws:
  `SVNException`
Since:
  1.2.0, SVN 1.5.0
