Constructor Detail

FS_Win32_Cygwin

public FS_Win32_Cygwin()

Constructor

FS_Win32_Cygwin

protected FS_Win32_Cygwin(FS src)

Constructor

Parameters:

src - instance whose attributes to copy

Method Detail

isCygwin

public static boolean isCygwin()

Whether cygwin is found

Returns:

true if cygwin is found

newInstance

public FS newInstance()

Create a new instance of the same type of FS.

Overrides:

newInstance in class FS_Win32

Returns:

a new instance of the same type of FS.

resolve

public File resolve(File dir,
                    String pn)

Resolve this file to its actual path name that the JRE can use.

This method can be relatively expensive. Computing a translation may require forking an external process per path name translated. Callers should try to minimize the number of translations necessary by caching the results.

Not all platforms and JREs require path name translation. Currently only Cygwin on Win32 require translation for Cygwin based paths.

Overrides:

resolve in class FS

Parameters:

dir - directory relative to which the path name is.

pn - path name to translate.

Returns:

the translated path. new File(dir,name) if this platform does not require path name translation.

userHomeImpl

protected File userHomeImpl()

Determine the user's home directory (location where preferences are).

Overrides:

userHomeImpl in class FS_Win32

Returns:

the user's home directory; null if the user does not have one.

runInShell

public ProcessBuilder runInShell(String cmd,
                                 String[] args)

Initialize a ProcessBuilder to run a command using the system shell.

Overrides:

runInShell in class FS_Win32

Parameters:

cmd - command to execute. This string should originate from the end-user, and thus is platform specific.

args - arguments to pass to command. These should be protected from shell evaluation.

Returns:

a partially completed process builder. Caller should finish populating directory, environment, and then start the process.

relativize

public String relativize(String base,
                         String other)

See FileUtils.relativizePath(String, String, String, boolean).

Overrides:

relativize in class FS

Parameters:

base - The path against which other should be relativized.

other - The path that will be made relative to base.

Returns:

A relative path that, when resolved against base, will yield the original other.

FileUtils.relativizePath(String, String, String, boolean)

runHookIfPresent

public ProcessResult runHookIfPresent(Repository repository,
                                      String hookName,
                                      String[] args,
                                      OutputStream outRedirect,
                                      OutputStream errRedirect,
                                      String stdinArgs)
                               throws JGitInternalException

Checks whether the given hook is defined for the given repository, then runs it with the given arguments.

Overrides:

runHookIfPresent in class FS

Parameters:

repository - The repository for which a hook should be run.

hookName - The name of the hook to be executed.

args - Arguments to pass to this hook. Cannot be null, but can be an empty array.

outRedirect - A print stream on which to redirect the hook's stdout. Can be null, in which case the hook's standard output will be lost.

errRedirect - A print stream on which to redirect the hook's stderr. Can be null, in which case the hook's standard error will be lost.

stdinArgs - A string to pass on to the standard input of the hook. May be null.

Returns:

The ProcessResult describing this hook's execution.

Throws:

JGitInternalException - if we fail to run the hook somehow. Causes may include an interrupted process or I/O errors.
