Lonami Exo f8264abb5a Clean-up client's __init__ and remove entity cache
Entity cache uses are removed. It was a source of ever-growing memory
usage that has to be reworked. This affects everything that tried to
obtain an input entity, input sender or input chat (such as the
SenderGetter or calls to _get_entity_pair). Input entities need to be
reworked in any case.

Its removal also affects the automatic cache of any raw API request.

Raise last error parameter is removed, and its behaviour made default.

The connection type parameter has been removed, since users really have
no need to change it.

A few more attributes have been made private, since users should not
mess with those.

"""
Occurs whenever you sign in as a bot and a user
sends an inline query such as ``@bot query``.
Args:
users (`entity`, optional):
May be one or more entities (username/peer/etc.), preferably IDs.
By default, only inline queries from these users will be handled.
blacklist_users (`bool`, optional):
Whether to treat the users as a blacklist instead of
as a whitelist (default). This means that every chat
will be handled *except* those specified in ``users``
which will be ignored if ``blacklist_users=True``.
pattern (`str`, `callable`, `Pattern`, optional):
If set, only queries matching this pattern will be handled.
You can specify a regex-like string which will be matched
against the message, a callable function that returns `True`
if a message is acceptable, or a compiled regex pattern.
Example
.. code-block:: python
from telethon import events
@client.on(events.InlineQuery)

builder = event.builder
# Two options (convert user text to UPPERCASE or lowercase)

Answers the inline query with the given results.
See the documentation for `builder` to know what kind of answers
can be given.
Args:
results (`list`, optional):
A list of :tl:`InputBotInlineResult` to use.
You should use `builder` to create these:
.. code-block:: python
builder = inline.builder
r1 = builder.article('Be nice', text='Have a nice day')
r2 = builder.article('Be bad', text="I don't like you")
await inline.answer([r1, r2])
You can send up to 50 results as documented in
https://core.telegram.org/bots/api#answerinlinequery.
Sending more will raise ``ResultsTooMuchError``,
and you should consider using `next_offset` to
paginate them.
cache_time (`int`, optional):
For how long this result should be cached on
the user's client. Defaults to 0 for no cache.
gallery (`bool`, optional):
Whether the results should show as a gallery (grid) or not.
next_offset (`str`, optional):
The offset the client will send when the user scrolls the
results and it repeats the request.
private (`bool`, optional):
Whether the results should be cached by Telegram
(not private) or by the user's client (private).
switch_pm (`str`, optional):
If set, this text will be shown in the results
to allow the user to switch to private messages.
switch_pm_param (`str`, optional):
Optional parameter to start the bot with if
`switch_pm` was used.
Example:
.. code-block:: python
@bot.on(events.InlineQuery)
async def handler(event):
builder = event.builder
rev_text = event.text[::-1]
