Package: fake-winreg
fake_winregVersion v1.6.3 as of 2023-07-20 seeChangelogFUNCTIONtest winreg functions on a fake registry on windows and linux, without messing up Your real registry.Fully type annotated and documented, so You can enjoy the type hints in Your favorite IDEThis is perfect for TDD, creating registry related code and covering most issues before You hit a real registry with Your tests.If You want to see real life examples, check outlib_registryget all winreg function names, type hints and constants, even on linux in Your favorite IDEyou plug in this “fake _winreg” and can test all Your Registry related functions on linux, wine, windowsall the predefined HKEY_*, REG_*, KEY_* constants are there.You might even test against a set of different fake registriesyou can use (almost) all winreg functions against a “fake” registryit behaves very much like the real “winreg” (version 3.3),
like not accepting keyword arguments for most functions,
accepting sub_keys to be “None” or “blank” in some, but not all functions, etc.it raises the same Exceptions like winregread, write registry values and keys, etc.LIMITATIONSthere are no access rights - sam is not supported.
That means You can read/write/delete Keys and values in the fake registry,
even if You opened the key with access right “KEY_READ”.
You can Delete Keys and Values in HKEY_LOCAL_MACHINE and so on, even if You dont have Admin Rights.
This is not an security issue, since You test against a fake registry - and You test mostly Your own software.
If You need it, contributions are welcome ! (somehow it would make sense for TDD to have it)at the moment you can not dump a real registry and save it, in order to use it as a fake registry - that means
all the keys You need, You have to set manually at the moment.
if I catch the time, I will polish up my old project “fingerprint” and make a compatible file format to dump / read / write registry branches.some (few) winreg functions are not implemented - if You miss out something, give me a note, i will integrate itobviously we can not connect to the registry of another windows computer over the networkKEY_WOW64_32KEY is not supported.

    Establishes a connection to a predefined registry handle on another computer, and returns a new handle object.
    the function does NOT accept named parameters, only positional parameters



    Parameter
    ---------

    computer_name:
        the name of the remote computer, of the form r"\\computername" or simply "computername"
        If None or '', the local computer is used.

        if the computer name can not be resolved on the network,fake_winreg will deliver:
         "OSError: [WinError 1707] The network address is invalid"

        if the computer_name given can be reached, we finally raise:
        "SystemError: System error 53 has occurred. The network path was not found"


    key:
        the predefined handle to connect to, or one of the predefined HKEY_* constants.



    Returns
    -------

    the handle of the opened key. If the function fails, an OSError exception is raised.



    Exceptions
    ----------

    OSError: [WinError 1707] The network address is invalid
        if the computer name can not be resolved

    FileNotFoundError: [WinError 53] The network path was not found
        if the network path is invalid

    OSError: [WinError 6] The handle is invalid
        if parameter key is invalid

    TypeError: None is not a valid HKEY in this context
        if parameter key is None


    TypeError: The object is not a PyHKEY object
        if parameter key is not integer or PyHKEY type

    OverflowError: int too big to convert
        if parameter key is > 64 Bit Integer Value

    TypeError: ConnectRegistry() got some positional-only arguments passed as keyword arguments: '<key>'
        if a keyword (named) parameter was passed



    Events
    ------

    winreg.ConnectRegistry auditing event (NOT IMPLEMENTED), with arguments computer_name, key.

    OSError: [WinError 6] The handle is invalid

    >>> # must not accept keyword parameters

    Traceback (most recent call last):
        ...
    TypeError: ConnectRegistry() got some positional-only arguments passed as keyword arguments: 'computer_name, key'

    """CloseKeydefCloseKey(hkey:Union[int,HKEYType])->None:# noqa"""
    Closes a previously opened registry key.

    the function does NOT accept named parameters, only positional parameters

    Note: If hkey is not closed using this method (or via hkey.Close()), it is closed when the hkey object is destroyed by Python.



    Parameter
    ---------

    hkey:
        the predefined handle to connect to, or one of the predefined HKEY_* constants.



    Exceptions
    ----------

    OSError: [WinError 6] The handle is invalid
        if parameter key is invalid

    TypeError: The object is not a PyHKEY object
        if parameter key is not integer or PyHKEY type

    OverflowError: int too big to convert
        if parameter key is > 64 Bit Integer Value

    TypeError: CloseKey() got some positional-only arguments passed as keyword arguments: '<key>'
        if a keyword (named) parameter was passed



    Examples
    --------

    >>> # Setup
    >>> fake_registry = fake_reg_tools.get_minimal_windows_testregistry()
    >>> load_fake_registry(fake_registry)

    >>> # Test
    >>> hive_key = ConnectRegistry(None, HKEY_LOCAL_MACHINE)
    >>> CloseKey(HKEY_LOCAL_MACHINE)

    >>> # Test hkey = None
    >>> hive_key = ConnectRegistry(None, HKEY_LOCAL_MACHINE)
    >>> CloseKey(None)  # noqa

    >>> # does not accept keyword parameters
    >>> hive_key = ConnectRegistry(None, HKEY_LOCAL_MACHINE)
    >>> CloseKey(hkey=HKEY_LOCAL_MACHINE)
    Traceback (most recent call last):
        ...
    TypeError: CloseKey() got some positional-only arguments passed as keyword arguments: 'hkey'

    """CreateKeydefCreateKey(key:Handle,sub_key:Optional[str])->PyHKEY:# noqa"""
    Creates or opens the specified key.

    The sub_key can contain a directory structure like r'Software\\xxx\\yyy' - all the parents to yyy will be created

    the function does NOT accept named parameters, only positional parameters


    Result
    ------

    If key is one of the predefined keys, sub_key may be None or empty string,
    and a new handle will be returned with access KEY_WRITE

    If the key already exists, this function opens the existing key.
    otherwise it will return the handle to the new created key with access KEY_WRITE


    From original winreg description (this is wrong):
        If key is one of the predefined keys, sub_key may be None.
        In that case, the handle returned is the same key handle passed in to the function.
        I always get back a different handle, this seems to be wrong (needs testing)

    Parameter
    ---------

    key:
        an already open key, or one of the predefined HKEY_* constants.

    sub_key:
        a string that names the key this method opens or creates.
        sub_key can be None or empty string when the key is one of the predefined hkeys


    Exceptions
    ----------

    PermissionError: [WinError 5] Access is denied
        if You dont have the right to Create the Key (at least KEY_CREATE_SUBKEY)

    OSError: [WinError 1010] The configuration registry key is invalid
        if the function fails to create the Key

    OSError: [WinError 6] The handle is invalid
        if parameter key is invalid

    TypeError: None is not a valid HKEY in this context
        if parameter key is None

    TypeError: The object is not a PyHKEY object
        if parameter key is not integer or PyHKEY type

    OverflowError: int too big to convert
        if parameter key is > 64 Bit Integer Value

    TypeError: CreateKey() argument 2 must be str or None, not <type>
        if the subkey is anything else then str or None

    OSError: [WinError 1010] The configuration registry key is invalid
        if the subkey is None or empty string, and key is not one of the predefined HKEY Constants

    TypeError: CreateKey() got some positional-only arguments passed as keyword arguments: '<key>'
        if a keyword (named) parameter was passed

    This method retrieves the data for a key’s first value that has a NULL name.
    But the underlying API call doesn’t return the type, so always use QueryValueEx() if possible.

    Parameter
    ---------

    key:
        the predefined handle to connect to, or one of the predefined HKEY_* constants.

    sub_key:
        None, or a string that names the key this method sets the default value
        If the key specified by the sub_key parameter does not exist, the SetValue function creates it.

    type:
        an integer that specifies the type of the data. Currently this must be REG_SZ,
        meaning only strings are supported. Use the SetValueEx() function for support for other data types.

    value:
        a string that specifies the new value.
        Value lengths are limited by available memory. Long values (more than 2048 bytes) should be stored
        as files with the filenames stored in the configuration registry. This helps the registry perform efficiently.
        The key identified by the key parameter must have been opened with KEY_SET_VALUE access.    (NOT IMPLEMENTED)

    Stores data in the value field of an open registry key.

    value_name is a string that names the subkey with which the value is associated.
    if value is None, or '' it sets the default value* of the Key

    the function does NOT accept named parameters, only positional parameters

    Parameter
    ---------

    key:
        the predefined handle to connect to, or one of the predefined HKEY_* constants.
        The key identified by the key parameter must have been opened with KEY_SET_VALUE access.    (NOT IMPLEMENTED))
        To open the key, use the CreateKey() or OpenKey() methods.

    value_name:
        None, or a string that identifies the value to set
        if value is None, or '' it sets the default value* of the Key

        * Remark : this is the Value what is shown in Regedit as "(Standard)" or "(Default)"
        it is usually not set, but You can set it to any data and datatype - but then it will
        only be readable with QueryValueEX, not with QueryValue

    reserved:
        reserved is a reserved integer, and should be zero. reserved can be anything – zero is always passed to the API.

    type:
        type is an integer that specifies the type of the data. (see table)

    value:
        value is a new value.
        Value lengths are limited by available memory. Long values (more than 2048 bytes)
        should be stored as files with the filenames stored in the configuration registry. This helps the registry perform efficiently.
