- Pyrogram core is now fully asynchronous - Ditched Python 3.5, welcome 3.6 as minimum version. - Moved all types to pyrogram.types - Turned the Filters class into a module (filters) - Moved all filters to pyrogram.filters - Moved all handlers to pyrogram.handlers - Moved all emoji to pyrogram.emoji - Renamed pyrogram.api to pyrogram.raw - Clock is now synced with server's time - Telegram schema updated to Layer 117 - Greatly improved the TL compiler (proper type-constructor hierarchy) - Added "do not edit" warning in generated files - Crypto parts are executed in a thread pool to avoid blocking the event loop - idle() is now a separate function (it doesn't deal with Client instances) - Async storage, async filters and async progress callback (optional, can be sync too) - Added getpass back, for hidden password inputs

"""Get the total count of messages in a chat.
|
|
|
|
.. note::
|
|
|
|
Due to Telegram latest internal changes, the server can't reliably find anymore the total count of messages
|
|
a **private** or a **basic group** chat has with a single method call. To overcome this limitation, Pyrogram
|
|
has to iterate over all the messages. Channels and supergroups are not affected by this limitation.
|
|
|
|
Parameters:
|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
|
|
Returns:
|
|
``int``: On success, the chat history count is returned.
|
|
|
|
Example:
|
|
.. code-block:: python
|
|
|

app.get_history_count("pyrogramchat")
