|Method||extendedRequest||This is the extension mechanism for SFTP. The other side can send us arbitrary requests.|
|Method||_setAttrs||NOTE: this function assumes it runs as the logged-in user: i.e. under _runAsUser()|
Called when the client sends their version info.
otherVersion is an integer representing the version of the SFTP protocol they are claiming. extData is a dictionary of extended_name : extended_data items. These items are sent by the client to indicate additional features.This method should return a dictionary of extended_name : extended_data items. These items are the additional features (if any) supported by the server.
|Parameters||filename||a string representing the file to open.|
|flags||an integer of the flags to open the file with, ORed together. The flags and their values are listed at the bottom of this file.|
|attrs||a list of attributes to open the file with. It is a dictionary,
consisting of 0 or more keys. The possible keys are:
size: the size of the file in bytes uid: the user ID of the file as an integer gid: the group ID of the file as an integer permissions: the permissions of the file with as an integer. the bit representation of this field is defined by POSIX. atime: the access time of the file as seconds since the epoch. mtime: the modification time of the file as seconds since the epoch. ext_*: extended attributes. The server is not required to understand this, but it may.
NOTE: there is no way to indicate text or binary files. it is up to the SFTP client to deal with this.This method returns an object that meets the ISFTPFile interface. Alternatively, it can return a
Remove the given file.This method returns when the remove succeeds, or a Deferred that is called back when it succeeds.
|Parameters||filename||the name of the file as a string.|
Rename the given file.This method returns when the rename succeeds, or a
Deferredthat is called back when it succeeds. If the rename fails,
renameFilewill raise an implementation-dependent exception.
|Parameters||oldpath||the current location of the file.|
|newpath||the new file name.|
Make a directory.This method returns when the directory is created, or a Deferred that is called back when it is created.
|Parameters||path||the name of the directory to create as a string.|
|attrs||a dictionary of attributes to create the directory with. Its meaning is
the same as the attrs in the |
Remove a directory (non-recursively)
It is an error to remove a directory that has files or directories in it.This method returns when the directory is removed, or a Deferred that is called back when it is removed.
|Parameters||path||the directory to remove.|
Open a directory for scanning.
This method returns an iterable object that has a close() method, or a Deferred that is called back with same.
The close() method is called when the client is finished reading from the directory. At this point, the iterable will no longer be used.
The iterable should return triples of the form (filename, longname, attrs) or Deferreds that return the same. The sequence must support __getitem__, but otherwise may be any 'sequence-like' object.
filename is the name of the file relative to the directory. logname is an expanded format of the filename. The recommended format is: -rwxr-xr-x 1 mjos staff 348911 Mar 25 14:29 t-filexfer 1234567890 123 12345678 12345678 12345678 123456789012
The first line is sample output, the second is the length of the field. The fields are: permissions, link count, user owner, group owner, size in bytes, modification time.attrs is a dictionary in the format of the attrs argument to openFile.
|Parameters||path||the directory to open.|
Return the attributes for the given path.This method returns a dictionary in the same format as the attrs argument to openFile or a Deferred that is called back with same.
|Parameters||path||the path to return attributes for as a string.|
|followLinks||a boolean. If it is True, follow symbolic links and return attributes for the real path at the base. If it is False, return attributes for the specified path.|
Set the attributes for the path.This method returns when the attributes are set or a Deferred that is called back when they are.
|Parameters||path||the path to set attributes for as a string.|
|attrs||a dictionary in the same format as the attrs argument to |
Find the root of a set of symbolic links.This method returns the target of the link, or a Deferred that returns the same.
|Parameters||path||the path of the symlink to read.|
Create a symbolic link.This method returns when the link is made, or a Deferred that returns the same.
|Parameters||linkPath||the pathname of the symlink as a string.|
|targetPath||the path of the target of the link as a string.|
Convert any path to an absolute path.This method returns the absolute path as a string, or a Deferred that returns the same.
|Parameters||path||the path to convert as a string.|
This is the extension mechanism for SFTP. The other side can send us arbitrary requests.
If we don't implement the request given by extendedName, raise NotImplementedError.The return value is a string, or a Deferred that will be called back with a string.
|Parameters||extendedName||the name of the request as a string.|
|extendedData||the data the other side sent with the request, as a string.|
