[docs]class BinaryDataNotification: """ ``class BinaryDataNotification`` provides an interface for receiving event notifications. Usage requires inheriting from this interface, overriding the relevant event handlers, and registering the `BinaryDataNotification` instance with a `BinaryView` using the `register_notification` method. By default, a `BinaryDataNotification` instance receives notifications for all available notification types. It is recommended for users of this interface to initialize the `BinaryDataNotification` base class with with specific callbacks of interest by passing the appropriate `NotificationType` flags into the `__init__` constructor. Handlers provided by the user should aim to limit the amount of processing within the callback. The callback context holds a global lock, preventing other threads from making progress during the callback phase. While most of the API can be used safely during this time, care must be taken when issuing a call that can block, as waiting for a thread requiring the global lock can result in deadlock. The `NotificationBarrier` is a special `NotificationType` that is disabled by default. To enable it, the `NotificationBarrier` flag must be passed to `__init__`. This notification is designed to facilitate efficient batch processing of other notification types. The idea is to collect other notifications of interest into a cache, which can be very efficient as it doesn't require additional locks. After some time, the core generates a `NotificationBarrier` event, providing a safe context to move the cache for processing by a different thread. To control the time of the next `NotificationBarrier` event, return the desired number of milliseconds until the next event from the `NotificationBarrier` callback. Returning zero quiesces future `NotificationBarrier` events. If the `NotificationBarrier` is quiesced, the reception of a new callback of interest automatically generates a new `NotificationBarrier` call after that notification is delivered. This mechanism effectively allows throttling and quiescing when necessary. .. note:: Note that the core generates a `NotificationBarrier` as part of the `BinaryDataNotification` registration \ process. Registering the same `BinaryDataNotification` instance again results in a gratuitous `NotificationBarrier` \ event, which can be useful in situations requiring a safe context for processing due to some other asynchronous \ event (e.g., user interaction). :Example: >>> class NotifyTest(binaryninja.BinaryDataNotification): ... def __init__(self): ... super(NotifyTest, self).__init__(binaryninja.NotificationType.NotificationBarrier | binaryninja.NotificationType.FunctionLifetime | binaryninja.NotificationType.FunctionUpdated) ... self.received_event = False ... def notification_barrier(self, view: 'BinaryView') -> int: ... has_events = self.received_event ... self.received_event = False ... log_info("notification_barrier") ... if has_events: ... return 250 ... else: ... return 0 ... def function_added(self, view: 'BinaryView', func: '_function.Function') -> None: ... self.received_event = True ... log_info("function_added") ... def function_removed(self, view: 'BinaryView', func: '_function.Function') -> None: ... self.received_event = True ... log_info("function_removed") ... def function_updated(self, view: 'BinaryView', func: '_function.Function') -> None: ... self.received_event = True ... log_info("function_updated") ... >>> >>> bv.register_notification(NotifyTest()) >>> """ def __init__(self, notifications: NotificationType = None): self.notifications = notifications

[docs]class BinaryView: """ ``class BinaryView`` implements a view on binary data, and presents a queryable interface of a binary file. One key job of BinaryView is file format parsing which allows Binary Ninja to read, write, insert, remove portions of the file given a virtual address. For the purposes of this documentation we define a virtual address as the memory address that the various pieces of the physical file will be loaded at. A binary file does not have to have just one BinaryView, thus much of the interface to manipulate disassembly exists within or is accessed through a BinaryView. All files are guaranteed to have at least the ``Raw`` BinaryView. The ``Raw`` BinaryView is simply a hex editor, but is helpful for manipulating binary files via their absolute addresses. BinaryViews are plugins and thus registered with Binary Ninja at startup, and thus should **never** be instantiated directly as this is already done. The list of available BinaryViews can be seen in the BinaryViewType class which provides an iterator and map of the various installed BinaryViews:: >>> list(BinaryViewType) [<view type: 'Raw'>, <view type: 'ELF'>, <view type: 'Mach-O'>, <view type: 'PE'>] >>> BinaryViewType['ELF'] <view type: 'ELF'> To open a file with a given BinaryView the following code is recommended: >>> with load("/bin/ls") as bv: ... bv <BinaryView: '/bin/ls', start 0x100000000, len 0x142c8> `By convention in the rest of this document we will use bv to mean an open and, analyzed, BinaryView of an executable file.` When a BinaryView is open on an executable view analysis is automatically run unless specific named parameters are used to disable updates. If such a parameter is used, updates can be triggered using the :py:func:`update_analysis_and_wait` method which disassembles the executable and returns when all disassembly and analysis is complete:: >>> bv.update_analysis_and_wait() >>> Since BinaryNinja's analysis is multi-threaded (depending on version) this can also be done in the background by using the :py:func:`update_analysis` method instead. By standard python convention methods which start with '_' should be considered private and should not be called externally. Additionally, methods which begin with ``perform_`` should not be called directly either and are used explicitly for subclassing a BinaryView. .. note:: An important note on the ``*_user_*()`` methods. Binary Ninja makes a distinction between edits \ performed by the user and actions performed by auto analysis. Auto analysis actions that can quickly be recalculated \ are not saved to the database. Auto analysis actions that take a long time and all user edits are stored in the \ database (e.g. :py:func:`remove_user_function` rather than :py:func:`remove_function`). Thus use ``_user_`` methods if saving \ to the database is desired.

[docs] def parse_expression(self, expression: str, here: int = 0) -> int: r""" Evaluates a string expression to an integer value. The parser uses the following rules: - Symbols are defined by the lexer as ``[A-Za-z0-9_:<>][A-Za-z0-9_:$\-<>]+`` or anything enclosed in either single or double quotes - Symbols are everything in ``bv.symbols``, unnamed DataVariables (i.e. ``data_00005000``), unnamed functions (i.e. ``sub_00005000``), or section names (i.e. ``.text``) - Numbers are defaulted to hexadecimal thus `_printf + 10` is equivalent to `printf + 0x10` If decimal numbers required use the decimal prefix. - Since numbers and symbols can be ambiguous its recommended that you prefix your numbers with the following: - ``0x`` - Hexadecimal - ``0n`` - Decimal - ``0`` - Octal - In the case of an ambiguous number/symbol (one with no prefix) for instance ``12345`` we will first attempt to look up the string as a symbol, if a symbol is found its address is used, otherwise we attempt to convert it to a hexadecimal number. - The following operations are valid: ``+, -, \*, /, %, (), &, \|, ^, ~, ==, !=, >, <, >=, <=`` - Comparision operators return 1 if the condition is true, 0 otherwise. - In addition to the above operators there are dereference operators similar to BNIL style IL: - ``[<expression>]`` - read the `current address size` at ``<expression>`` - ``[<expression>].b`` - read the byte at ``<expression>`` - ``[<expression>].w`` - read the word (2 bytes) at ``<expression>`` - ``[<expression>].d`` - read the dword (4 bytes) at ``<expression>`` - ``[<expression>].q`` - read the quadword (8 bytes) at ``<expression>`` - The ``$here`` (or more succinctly: ``$``) keyword can be used in calculations and is defined as the ``here`` parameter, or the currently selected address - The ``$start``/``$end`` keyword represents the address of the first/last bytes in the file respectively - Arbitrary magic values (name-value-pairs) can be added to the expression parser via the :py:func:`add_expression_parser_magic_value` API. Notably, the debugger adds all register values into the expression parser so they can be used directly when navigating. The register values can be referenced like `$rbp`, `$x0`, etc. For more details, refer to the related [debugger docs](https://docs.binary.ninja/guide/debugger/index.html#navigating-the-binary). :param str expression: Arithmetic expression to be evaluated :param int here: (optional) Base address for relative expressions, defaults to zero :rtype: int """ offset = ctypes.c_ulonglong() errors = ctypes.c_char_p() if not core.BNParseExpression(self.handle, expression, offset, here, errors): assert errors.value is not None, "core.BNParseExpression returned errors set to None" error_str = errors.value.decode("utf-8") core.free_string(errors) raise ValueError(error_str) return offset.value
