ConnectionABC
¶ Bases:

_path2str
(path: Optional[_SPATH]) → str¶ Converts pathlib.Path, SSHPath or plain str to string.
Also remove any rtailing backslashes.
Parameters: path ( ssh_utilities.typeshed._SPATH
) – path to convert to string, if string is passed, then just returns itRaises: FileNotFoundError
– if path is not instance of str, Path or SSHPath
-
_to_str
(connection_name: str, host_name: str, address: Optional[str], user_name: str, ssh_key: Union[pathlib.Path, str, None], thread_safe: bool) → str¶ Aims to ease persistance, returns string representation of instance.
With this method all data needed to initialize class are saved to sting and connection can be reinitialized with from_str method of conection.Connection class.
Parameters: - connection_name (str) – SSHConnection or LocalConnection
- host_name (str) – name of remote server
- address (str) – server address in case of remote connection
- user_name (str) – server login name
- ssh_key (Optional[Union[Path, str]]) – file with public key, pass none for LocalConnection
- thread_safe (bool) – make connection object thread safe so it can be safely accessed from any number of threads, it is disabled by default to avoid performance penalty of threading locks
Returns: string representation of the class
Return type: str

, optional) – [description], by default None - input (Optional[str], optional) – [description], by default None
- stdin (_FILE, optional) – [description], by default None
- stdout (_FILE, optional) – [description], by default None

Warning
New environment variables defined by env might get silently rejected by the server.
Currentlly it is only possible to use input agrgument, not stdin and send data to process only once at the begining. It is still under developement

download_tree
(remote_path: _SPATH, local_path: _SPATH, include: _GLOBPAT = None, exclude: _GLOBPAT = None, remove_after: bool = True, quiet: bool = False)¶ Download directory tree from remote.
Remote directory must exist otherwise exception is raised.
Parameters: - remote_path (
ssh_utilities.typeshed._SPATH
) – path to directory which should be downloaded - local_path (
ssh_utilities.typeshed._SPATH
) – directory to copy to, must be full path! - remove_after (bool) – remove remote copy after directory is uploaded
- include (
ssh_utilities.typeshed._GLOBPAT
) – glob pattern of files to include in copy, can be used simultaneously with exclude, default is None = no filtering - exclude (
ssh_utilities.typeshed._GLOBPAT
) – glob pattern of files to exclude in copy, can be used simultaneously with include, default is None = no filtering - quiet (Literal[True, False, "stats", "progress"]) – if True informative messages are suppresssed if False all is printed, if stats all statistics except progressbar are suppressed if progress only progressbar is suppressed
Warning
both paths must be full: <some_remote_path>/my_directory -> <some_local_path>/my_directory
Raises: FileNotFoundError

rmtree
(path: _SPATH, ignore_errors: bool = False, quiet: bool = True)¶ Recursively remove directory tree.
Parameters: - path (
ssh_utilities.typeshed._SPATH
) – directory to be recursively removed - ignore_errors (bool) – if True only log warnings do not raise exception
- quiet (bool) – if True informative messages are suppresssed
Raises: FileNotFoundError

upload_tree
(local_path: _SPATH, remote_path: _SPATH, include: _GLOBPAT = None, exclude: _GLOBPAT = None, remove_after: bool = True, quiet: bool = False)¶ Upload directory tree to remote.
Local path must exist otherwise, exception is raised.
Parameters: - local_path (
ssh_utilities.typeshed._SPATH
) – path to directory which should be uploaded - remote_path (
ssh_utilities.typeshed._SPATH
) – directory to copy to, must be full path! - remove_after (bool) – remove local copy after directory is uploaded

run
(args: _CMD, *, suppress_out: bool, quiet: bool = True, bufsize: int = -1, executable: _SPATH = None, input: Optional[str] = None, stdin: _FILE = None, stdout: _FILE = None, stderr: _FILE = None, capture_output: bool = False, shell: bool = False, cwd: _SPATH = None, timeout: Optional[float] = None, check: bool = False, encoding: Optional[str] = None, errors: Optional[str] = None, text: Optional[bool] = None, env: _ENV = None, universal_newlines: bool = False) → _Subprocess1¶ Excecute command on remote, has simillar API to subprocess run.
Parameters: - args (
ssh_utilities.typeshed._CMD
) – string, Path-like object or a list of strings. If it is a list it will be joined to string with whitespace delimiter. - suppress_out (bool) – whether to print command output to console, this is required keyword argument
- quiet (bool, optional) – whether to print other function messages, by default True
- bufsize (int, optional) – buffer size, 0 turns off buffering, 1 uses line buffering, and any number greater than 1 (>1) uses that specific buffer size. This applies ti underlying paramiko client as well as stdin, stdout and stderr PIPES, by default -1
- executable (
ssh_utilities.typeshed._SPATH
, optional) – [description], by default None - input (Optional[str], optional) – [description], by default None
- stdin (_FILE, optional) – [description], by default None
- stdout (_FILE, optional) – [description], by default None
- stderr (_FILE, optional) – [description], by default None
- capture_output (bool, optional) – if true then lightweight result object with same API as subprocess.CompletedProcess is returned. Same as passing PIPE to stdout and stderr. Both options cannot be used at the same time, by default False
- shell (bool, optional) – requests a pseudo terminal from server, by default False
- cwd (_SPATH, optional) – execute command in this directory, by default None
- timeout (Optional[float], optional) – set, by default None
- check (bool, optional) – checks for command return code if other than 0 raises CalledProcessError, by default False
- encoding (Optional[str], optional) – encoding to use when decoding remote output, default is utf-8, by default None
- errors (Optional[str], optional) –
string that specifies how encoding and decoding errors are to be handled, see builtin function open documentation for more details, by default None
- text (Optional[bool], optional) – will select default encoding and open stdin, stdout and stderr streams in text mode. The default encoding, contrary to behaviour of subprocess module is not selected by locale.getpreferredencoding(False) but is always set to utf-8. By default None
- env (
ssh_utilities.typeshed._ENV
, optional) – optinal environment variables that will be merged into the existing environment. This is different to subprocess behaviour which creates new environment with only specified variables, by default None - universal_newlines (bool, optional) – an alias for text keyword argument, by default None
Warning
New environment variables defined by env might get silently rejected by the server.
Currentlly it is only possible to use input agrgument, not stdin and send data to process only once at the begining. It is still under developement
Returns: if capture_output is true, returns lightweight result object with same API as subprocess.CompletedProcess
Return type: Raises: ValueError
– if stdin and input are specified at the same timeValueError
– if capture_output and stdout and/or stderr are specified at the same timeValueError
– if text or universal_newlines is used simultaneously with” encoding and/or errors argumentsNotImplementedError
