Constructor Detail

### SVNDiffClient

    public SVNDiffClient(ISVNAuthenticationManager authManager,
                         ISVNOptions options)

  Constructs and initializes an SVNDiffClient object with the specified run-time configuration and authentication drivers.

  If `options` is null, then this SVNDiffClient will be using a default run-time configuration driver which takes client-side settings from the default SVN's run-time configuration area but is not able to change those settings (read more on `ISVNOptions` and `SVNWCUtil`).

  If `authManager` is null, then this SVNDiffClient will be using a default authentication and network layers driver (see `SVNWCUtil.createDefaultAuthenticationManager()`) which uses server-side settings and auth storage from the default SVN's run-time configuration area (or system properties if that area is not found).

Parameters:
  `authManager` - an authentication and network layers driver
  `options` - a run-time configuration options driver

### SVNDiffClient

    public SVNDiffClient(ISVNRepositoryPool repositoryPool,
                         ISVNOptions options)

  Constructs and initializes an SVNDiffClient object with the specified run-time configuration and repository pool object.

  If `options` is null, then this SVNDiffClient will be using a default run-time configuration driver which takes client-side settings from the default SVN's run-time configuration area but is not able to change those settings (read more on `ISVNOptions` and `SVNWCUtil`).

  If `repositoryPool` is null, then `SVNRepositoryFactory` will be used to create `repository access objects`.

Parameters:
  `repositoryPool` - a repository pool object
  `options` - a run-time configuration options driver

Method Detail

### setDiffGenerator

    public void setDiffGenerator(ISVNDiffGenerator diffGenerator)

  Sets the specified diff driver for this object to use for generating and writing file differences to an otput stream.

  If no specific diff driver was set in this way, a default one will be used (see `DefaultSVNDiffGenerator`).

  Parameters:
    `diffGenerator` - a diff driver
  See Also:
    `getDiffGenerator()`

### getDiffGenerator

    public ISVNDiffGenerator getDiffGenerator()

  Returns the diff driver being in use.

  If no specific diff driver was previously provided, a default one will be returned (see `DefaultSVNDiffGenerator`).

  Returns:
    the diff driver being in use
  See Also:
    `setDiffGenerator(ISVNDiffGenerator)`

### setMergeOptions

    public void setMergeOptions(SVNDiffOptions diffOptions)

  Sets diff options for this client to use in merge operations.

  Parameters:
    `diffOptions` - diff options object

### getMergeOptions

    public SVNDiffOptions getMergeOptions()

  Gets the diff options that are used in merge operations by this client. If none was provided by the user, one created as `new SVNDiffOptions()` will be returned and used further.

  Returns:
    diff options

### doDiff

    public void doDiff(SVNURL url,
                       SVNRevision pegRevision,
                       SVNRevision rN,
                       SVNRevision rM,
                       boolean recursive,
                       boolean useAncestry,
                       OutputStream result)
                throws SVNException

  Deprecated. use `doDiff(SVNURL, SVNRevision, SVNRevision, SVNRevision, SVNDepth, boolean, OutputStream)` instead

  Generates the differences for the specified URL taken from the two specified revisions and writes the result to the provided output stream.

  Corresponds to the SVN command line client's `'svn diff -r N:M URL'` command.

  Parameters:
    `url` - a repository location
    `pegRevision` - a revision in which `url` is first looked up
    `rN` - an old revision
    `rM` - a new revision
    `recursive` - true to descend recursively
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `result` - the target `OutputStream` where the differences will be written to
  Throws:
    `SVNException` - if one of the following is true:
    - at least one of `rN`, `rM` and `pegRevision` is invalid
    - at least one of `rN` and `rM` is a local revision (see `SVNRevision.isLocal()`)
    - `url` was not found in `rN`
    - `url` was not found in `rM`

### doDiff

    public void doDiff(SVNURL url,
                       SVNRevision pegRevision,
                       SVNRevision rN,
                       SVNRevision rM,
                       SVNDepth depth,
                       boolean useAncestry,
                       OutputStream result)
                throws SVNException

  Produces diff output which describes the delta between `url` in peg revision `pegRevision`, as it changed between `rN` and `rM`.

  If `pegRevision is `invalid`, behaves identically to `doDiff(SVNURL, SVNRevision, SVNURL, SVNRevision, SVNDepth, boolean, OutputStream)`, using `url` for both of that function's `url1` and `url2` arguments.

  All other options are handled identically to `doDiff(SVNURL, SVNRevision, SVNURL, SVNRevision, SVNDepth, boolean, OutputStream)`.

  `
  Parameters:
    `url` - a repository location
    `pegRevision` - a revision in which `url` is first looked up
    `rN` - an old revision
    `rM` - a new revision
    `depth` - tree depth to process
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `result` - the target `OutputStream` where the differences will be written to
  Throws:
    `SVNException` - if one of the following is true:
    - exception with `SVNErrorCode.CLIENT_BAD_REVISION` error code - if either of `rN` and `rM` is either `invalid` or `local`
    - exception with `SVNErrorCode.FS_NOT_FOUND` error code - `url` can not be found in either `rN` or `rM`
  Since:
    1.2, SVN 1.5

### doDiff

    public void doDiff(File path,
                       SVNRevision pegRevision,
                       SVNRevision rN,
                       SVNRevision rM,
                       boolean recursive,
                       boolean useAncestry,
                       OutputStream result)
                throws SVNException

  Deprecated. use `doDiff(File, SVNRevision, SVNRevision, SVNRevision, SVNDepth, boolean, OutputStream, Collection)` instead

  Generates the differences for the specified path taken from the two specified revisions and writes the result to the provided output stream.

  If `rM` is a local revision (see `SVNRevision.isLocal()`), then the Working Copy `path` is compared with the corresponding repository file at revision `rN` (that is similar to the SVN command line client's `'svn diff -r N path'` command).

  Otherwise if both `rN` and `rM` are non-local, then the repository location of `path` is compared for these revisions (`'svn diff -r N:M URL'`).

  Parameters:
    `path` - a Working Copy path
    `pegRevision` - a revision in which the repository location of `path` is first looked up
    `rN` - an old revision
    `rM` - a new revision (or a local one)
    `recursive` - true to descend recursively
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `result` - the target `OutputStream` where the differences will be written to
  Throws:
    `SVNException` - if one of the following is true:
    - at least one of `rN`, `rM` and `pegRevision` is invalid
    - both `rN` and `rM` are local revisions
    - `path` was not found in `rN`
    - `path` was not found in `rM`

### doDiff

    public void doDiff(File[] paths,
                       SVNRevision rN,
                       SVNRevision rM,
                       SVNRevision pegRevision,
                       SVNDepth depth,
                       boolean useAncestry,
                       OutputStream result,
                       Collection changeLists)
                throws SVNException

  Iterates over the passed in `paths` calling `doDiff(File, SVNRevision, SVNRevision, SVNRevision, SVNDepth, boolean, OutputStream, Collection)` for each one in the array.

  Parameters:
    `paths` - array of working copy paths
    `rN` - an old revision
    `rM` - a new revision
    `pegRevision` - a revision in which the repository location of `paths` is first looked up
    `depth` - tree depth to process

### doDiff

    public void doDiff(File path,
                       SVNRevision pegRevision,
                       SVNRevision rN,

                       Collection changeLists)
                throws SVNException

  Produces diff output which describes the delta between `path` in peg revision `pegRevision`, as it changed between `rN` and `rM`.

  If `rM` is neither `SVNRevision.BASE`, nor `SVNRevision.WORKING`, nor `SVNRevision.COMMITTED`, and if, on the contrary, `rN` is one of the aforementioned revisions, then a wc-against-url diff is performed; if `rN` also is not one of those revision constants, then a url-against-url diff is performed. Otherwise it's a url-against-wc diff.

  If `pegRevision is `invalid`, behaves identically to `doDiff(File, SVNRevision, File, SVNRevision, SVNDepth, boolean, OutputStream, Collection)`, using `path` for both of that function's `path1` and `path2` arguments.

  All other options are handled identically to `doDiff(File, SVNRevision, File, SVNRevision, SVNDepth, boolean, OutputStream, Collection)`.

  `
  Parameters:
    `path` - a Working Copy path
    `pegRevision` - a revision in which the repository location of `path` is first looked up
    `rN` - an old revision
    `rM` - a new revision
    `depth` - tree depth to process
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `result` - the target `OutputStream` where the differences will be written to
    `changeLists` - collection with changelist names
  Throws:
    `SVNException` - if one of the following is true:
    - exception with `SVNErrorCode.CLIENT_BAD_REVISION` error code - if either of `rN` and `rM` is `invalid`; if both `rN` and `rM` are either `SVNRevision.WORKING` or `SVNRevision.BASE`
    - exception with `SVNErrorCode.FS_NOT_FOUND` error code - `path` can not be found in either `rN` or `rM`

                throws SVNException

  Deprecated. use `doDiff(SVNURL, SVNRevision, SVNURL, SVNRevision, SVNDepth, boolean, OutputStream)` instead

  Generates the differences for the specified URLs taken from the two specified revisions and writes the result to the provided output stream.

  Corresponds to the SVN command line client's `'svn diff -r N:M URL1 URL2'` command.

  Parameters:
    `url1` - the first URL to be compared
    `rN` - a revision of `url1`
    `url2` - the second URL to be compared
    `rM` - a revision of `url2`
    `recursive` - true to descend recursively
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `result` - the target `OutputStream` where the differences will be written to
  Throws:
    `SVNException` - if one of the following is true:
    - at least one of `rN` and `rM` is invalid
    - `url1` was not found in `rN`
    - `url2` was not found in `rM`

                       OutputStream result)
                throws SVNException

  Produces diff output which describes the delta between `url1`/`rN` and `url2`/`rM`. Writes the output of the diff to `result`.

  If this client object uses `DefaultSVNDiffGenerator` and there was a non-null `base path` provided to it, the original path and modified path will have this base path stripped from the front of the respective paths. If the base path is not null but is not a parent path of the target, an exception with the `SVNErrorCode.BAD_RELATIVE_PATH` error code is thrown.

  `url1` and `url2` must both represent the same node kind -- that is, if `url1` is a directory, `url2` must also be, and if `url1` is a file, `url2` must also be.

  If `depth` is `SVNDepth.INFINITY`, diffs fully recursively. Else if it is `SVNDepth.IMMEDIATES`, diffs the named paths and their file children (if any), and diffs properties of subdirectories, but does not descend further into the subdirectories. Else if `SVNDepth.FILES`, behaves as if for `SVNDepth.IMMEDIATES` except doesn't diff properties of subdirectories. If `SVNDepth.EMPTY`, diffs exactly the named paths but nothing underneath them.

  `useAncestry` controls whether or not items being diffed will be checked for relatedness first. Unrelated items are typically transmitted to the editor as a deletion of one thing and the addition of another, but if this flag is true, unrelated items will be diffed as if they were related.

  If `ISVNDiffGenerator.isDiffDeleted()` returns true, then no diff output will be generated on deleted files.

  Generated headers are encoded using `ISVNDiffGenerator.getEncoding()`.

  Diffs output will not be generated for binary files, unless `ISVNDiffGenerator.isForcedBinaryDiff()` is true, in which case diffs will be shown regardless of the content types.

  If this client object uses `DefaultSVNDiffGenerator` then a caller can set `SVNDiffOptions` to it which will be used to pass additional options to the diff processes invoked to compare files.

  Parameters:
    `url1` - the first URL to be compared
    `rN` - a revision of `url1`
    `url2` - the second URL to be compared against `path1`
    `rM` - a revision of `url2`
    `depth` - tree depth to process
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `result` - the target `OutputStream` where the differences will be written to
  Throws:
    `SVNException` - in the following cases:
    exception with `SVNErrorCode.CLIENT_BAD_REVISION` error code - if either `rN` or `rM` is `invalid`

  Deprecated. use `doDiff(File, SVNRevision, SVNURL, SVNRevision, SVNDepth, boolean, OutputStream, Collection)` instead

  Generates the differences comparing the specified URL in a certain revision against either the specified Working Copy path or its repository location URL in the specified revision, and writes the result to the provided output stream.

  If `rN` is not a local revision (see `SVNRevision.isLocal()`), then its repository location URL as it is in the revision represented by `rN` is taken for comparison with `url2`.

  Corresponds to the SVN command line client's `'svn diff -r N:M PATH URL'` command.

  Parameters:
    `path1` - a WC path
    `rN` - a revision of `path1`
    `url2` - a repository location URL that is to be compared against `path1` (or its repository location)

  Deprecated. use `doDiff(File, SVNRevision, File, SVNRevision, SVNDepth, boolean, OutputStream, Collection)` instead

  Generates the differences comparing either the specified Working Copy paths or their repository location URLs (any combinations are possible) in the specified revisions and writes the result to the provided output stream.

  If both `rN` and `rM` are local revisions (see `SVNRevision.isLocal()`), then a Working Copy `path2` is compared against a Working Copy `path1`.

  If `rN` is a local revision but `rM` is not, then the repository location URL of `path2` as it is in the revision represented by `rM` is compared against the Working Copy `path1`.

  If `rM` is a local revision but `rN` is not, then the Working Copy `path2` is compared against the repository location URL of `path1` as it is in the revision represented by `rN`.

  If both `rN` and `rM` are non-local revisions, then the repository location URL of `path2` in revision `rM` is compared against the repository location URL of `path1` in revision `rN`.

  Parameters:
    `path1` - a WC path

                             ISVNDiffStatusHandler handler)
                      throws SVNException

  Produces a diff summary which lists the changed items between `path` in peg revision `pegRevision`, as it changed between `rN` and `rM`.

  If `pegRevision` is `invalid`, behaves identically to `doDiffStatus(File, SVNRevision, File, SVNRevision, SVNDepth, boolean, ISVNDiffStatusHandler)`, using `path` for both of that method's `path1` and `path2` argments.

  The method may report false positives if `useAncestry` is false, as described in the documentation for `doDiffStatus(File, SVNRevision, File, SVNRevision, SVNDepth, boolean, ISVNDiffStatusHandler)`.

  Calls `handler` for each difference with an `SVNDiffStatus` object describing the difference.

  See `doDiff(File, SVNRevision, SVNRevision, SVNRevision, SVNDepth, boolean, OutputStream, Collection)` for a description of the other parameters.

  Parameters:
    `path` - working copy path
    `rN` - left-hand revision
    `rM` - right-hand revision
    `pegRevision` - a revision in which the repository location of `path` is first looked up
    `depth` - tree depth to process
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `handler` - a diff status handler

                 throws SVNException

  Deprecated. use `doMerge(File, SVNRevision, File, SVNRevision, File, SVNDepth, boolean, boolean, boolean, boolean)` instead

  Applies the differences between two sources (using Working Copy paths to get corresponding URLs of the sources) to a Working Copy path.

  Corresponds to the SVN command line client's `'svn merge sourceWCPATH1@rev1 sourceWCPATH2@rev2 WCPATH'` command.

  If you need only to try merging your file(s) without actual merging, you should set `dryRun` to true. Your event handler will be dispatched status type information on the target path(s). If a path can be successfully merged, the status type will be `SVNStatusType.MERGED` for that path.

  Parameters:
    `path1` - the first source path
    `revision1` - a revision of `path1`
    `path2` - the second source path which URL is to be compared against the URL of `path1`
    `revision2` - a revision of `path2`
    `dstPath` - the target path to which the result should be applied
    `recursive` - true to descend recursively
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `force` - true to force the operation to run
    `dryRun` - if true then only tries the operation to run (to find out if a file can be merged successfully)
  Throws:
    `SVNException` - if one of the following is true:
    - at least one of `revision1` and `revision2` is invalid
    - `path1` has no URL
    - `path2` has no URL
    - the repository location of `path1` was not found in `revision1`
    - the repository location of `path2` was not found in `revision2`
    - `dstPath` is not under version control

### doMerge

    public void doMerge(File path1,
                        SVNRevision revision1,
                        File path2,
                        SVNRevision revision2,
                        File dstPath,
                        SVNDepth depth,
                        boolean useAncestry,
                        boolean force,
                        boolean dryRun,
                        boolean recordOnly)
                 throws SVNException

  Merges changes from `path1`/`revision1` to `path2`/`revision2` into the working-copy path `dstPath`.

  `path1` and `path2` must both represent the same node kind - that is, if `path1` is a directory, `path2` must also be, and if `path1` is a file, `path2` must also be.

  If `depth` is `SVNDepth.INFINITY`, merges fully recursively. Else if `SVNDepth.IMMEDIATES`, merges changes at most to files that are immediate children of `dstPath` and to directory properties of `dstPath` and its immediate subdirectory children. Else if `SVNDepth.FILES`, merges at most to immediate file children of `dstPath` and to `dstPath` itself. Else if `SVNDepth.EMPTY`, applies changes only to `dstPath` (i.e., directory property changes only).

  If `depth` is `SVNDepth.UNKNOWN`, uses the depth of `dstPath`.

  Uses `useAncestry` to control whether or not items being diffed will be checked for relatedness first. Unrelated items are typically transmitted to the editor as a deletion of one thing and the addition of another, but if this flag is true, unrelated items will be diffed as if they were related.

  If `force` is not set and the merge involves deleting locally modified or unversioned items the operation will fail. If `force` is set such items will be deleted.

  `merge options` is used to pass arguments to the merge processes (internal or external).

  If the caller's `ISVNEventHandler` is not null, then it will be called once for each merged target.

  If `recordOnly` is true, the merge isn't actually performed, but the mergeinfo for the revisions which would've been merged is recorded in the working copy (and must be subsequently committed back to the repository).

  If `dryRun` is true, the merge is carried out, and full notification feedback is provided, but the working copy is not modified.

  Note: this method requires repository access.

  Parameters:
    `path1` - left-hand working copy path
    `revision1` - revision of `path1`
    `path2` - right-hand working copy path
    `revision2` - revision of `path2`
    `dstPath` - target working copy path
    `depth` - tree depth to process
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `force` - true to force the operation to run
    `dryRun` - if true then runs merge without any file changes
    `recordOnly` - if true, records only the rusult of merge - mergeinfo data
  Throws:
    `SVNException` - in the following cases:
    exception with `SVNErrorCode.CLIENT_BAD_REVISION` error code - if either `revision1` or `revision2` is `invalid`
    exception with `SVNErrorCode.ENTRY_MISSING_URL` error code - if failed to retrieve url of either `path1` or `path2`

                 throws SVNException

  Merges changes from `path1`/`revision1` to `url2`/`revision2` into the working-copy path `dstPath`.

  `path1` and `url2` must both represent the same node kind - that is, if `path1` is a directory, `url2` must also be, and if `path1` is a file, `url2` must also be.

  If `depth` is `SVNDepth.INFINITY`, merges fully recursively. Else if `SVNDepth.IMMEDIATES`, merges changes at most to files that are immediate children of `dstPath` and to directory properties of `dstPath` and its immediate subdirectory children. Else if `SVNDepth.FILES`, merges at most to immediate file children of `dstPath` and to `dstPath` itself. Else if `SVNDepth.EMPTY`, applies changes only to `dstPath` (i.e., directory property changes only).

  If `depth` is `SVNDepth.UNKNOWN`, uses the depth of `dstPath`.

  Uses `useAncestry` to control whether or not items being diffed will be checked for relatedness first. Unrelated items are typically transmitted to the editor as a deletion of one thing and the addition of another, but if this flag is true, unrelated items will be diffed as if they were related.

  If `force` is not set and the merge involves deleting locally modified or unversioned items the operation will fail. If `force` is set such items will be deleted.

  `merge options` is used to pass arguments to the merge processes (internal or external).

  If the caller's `ISVNEventHandler` is not null, then it will be called once for each merged target.

  If `recordOnly` is true, the merge isn't actually performed, but the mergeinfo for the revisions which would've been merged is recorded in the working copy (and must be subsequently committed back to the repository).

  If `dryRun` is true, the merge is carried out, and full notification feedback is provided, but the working copy is not modified.

  Note: this method requires repository access.

  Parameters:
    `path1` - left-hand item - working copy path
    `revision1` - revision of `path1`
    `url2` - right-hand item - repository url
    `revision2` - revision of `url2`
    `dstPath` - target working copy path
    `depth` - tree depth to process
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `force` - true to force the operation to run
    `dryRun` - if true then runs merge without any file changes
    `recordOnly` - if true, records only the rusult of merge - mergeinfo data
  Throws:
    `SVNException` - in the following cases:
    exception with `SVNErrorCode.CLIENT_BAD_REVISION` error code - if either `revision1` or `revision2` is `invalid`
    exception with `SVNErrorCode.ENTRY_MISSING_URL` error code - if failed to retrieve the repository url of `path1`

  Deprecated. use `doMerge(SVNURL, SVNRevision, File, SVNRevision, File, SVNDepth, boolean, boolean, boolean, boolean)` instead

  Applies the differences between two sources (the repository location URL of a source Working Copy against a source URL) to a Working Copy path.

  If you need only to try merging your file(s) without actual merging, you should set `dryRun` to true. Your event handler will be dispatched status type information on the target path(s). If a path can be successfully merged, the status type will be `SVNStatusType.MERGED` for that path.

  Parameters:
    `url1` - the first source - a URL
    `revision1` - a revision of `url1`
    `path2` - the second source - a WC path that is to be compared against `url1`
    `revision2` - a revision of `path2`
    `dstPath` - the target path to which the result should be applied
    `recursive` - true to descend recursively
    `useAncestry` - if true then the paths ancestry will be noticed while calculating differences, otherwise not
    `force` - true to force the operation to run
    `dryRun` - if true then only tries the operation to run (to find out if a file can be merged successfully)
  Throws:
    `SVNException` - if one of the following is true:
    - at least one of `revision1` and `revision2` is invalid
    - `path2` has no URL
    - `url1` was not found in `revision1`
    - the repository location of `path2` was not found in `revision2`

                            throws SVNException

  Performs a reintegration merge of `srcPath` at `pegRevision` into `dstPath`.

  `dstPath` must be a single-revision, `SVNDepth.INFINITY`, pristine, unswitched working copy -- in other words, it must reflect a single revision tree, the "target". The mergeinfo on `srcPath` must reflect that all of the target has been merged into it.

  This kind of merge should be used for back merging (for example, merging branches back to trunk, in which case merge is carried out by comparing the latest trunk tree with the latest branch tree; i.e. the resulting difference is excatly the branch changes which will go back to trunk).

  All other options are handled identically to `doMerge(File, SVNRevision, File, SVNRevision, File, SVNDepth, boolean, boolean, boolean, boolean)`. The depth of the merge is always `SVNDepth.INFINITY`.

  If `pegRevision` is null or `invalid`, then it defaults to `SVNRevision.WORKING`.

  Note: this method requires repository access.

  Parameters:
    `srcPath` - working copy path
    `pegRevision` - a revision in which `srcPath` is first looked up
    `dstPath` - target working copy path
    `dryRun` - if true then only tries the operation to run (to find out if a file can be merged successfully)

                            throws SVNException

  Performs a reintegration merge of `srcURL` at `pegRevision` into `dstPath`.

  `dstPath` must be a single-revision, `SVNDepth.INFINITY`, pristine, unswitched working copy -- in other words, it must reflect a single revision tree, the "target". The mergeinfo on `srcPath` must reflect that all of the target has been merged into it.

  This kind of merge should be used for back merging (for example, merging branches back to trunk, in which case merge is carried out by comparing the latest trunk tree with the latest branch tree; i.e. the resulting difference is excatly the branch changes which will go back to trunk).

  All other options are handled identically to `doMerge(SVNURL, SVNRevision, SVNURL, SVNRevision, File, SVNDepth, boolean, boolean, boolean, boolean)`. The depth of the merge is always `SVNDepth.INFINITY`.

  If `pegRevision` is null or `invalid`, then it defaults to `SVNRevision.HEAD`.

  Note: this method requires repository access.

  Parameters:
    `srcURL` - repository url
    `pegRevision` - a revision in which `srcURL` is first looked up
    `dstPath` - target working copy path
    `dryRun` - if true then only tries the operation to run (to find out if a file can be merged successfully)
  Throws:
    `SVNException`

    1.2, SVN 1.5
