This should make it easier to maintain these methods, increase
reusability, and get rid of the async_generator dependency.
In the future, people could use this to more easily deal with
raw API themselves.
This one in particular may happen when iterating over messages,
perhaps more likely to happen if the group was created in a
different data center.
A small sleep of a few seconds also greatly increases the
chances of the error going away.
It was actually using FileLocation, which had the invalid expected
type for what was being returned. Instead it should have been this
other type.
In addition, more parameters are passed so that the method can have
all the information it needs to correctly cast the type.
Excepting ValueError when creating the SQLiteSession could hide
other errors (e.g. using a newer session file on an older version
of the library). Instead, the original error is raised, as if
sqlite3 was being imported within its __init__ method.
Letting _get_extension work for photos even when the only information
available is a stream or a few bytes allows sending arbitrary bytes
as photos, if force_document was not set to True explicitly.
* Create `_NOT_A_REQUEST` when needed. Currently, modifications
in the raised exception would be "global".
* `retries` parameters were actually attempts. This has been fixed
to actually be the amount of retries, so 0 now means don't retry.
* Helper function to deal with retries instead of using a range with
different styles every time.
Things like SQLAlchemy work correctly only for timezone-aware datetimes.
The returned TLObjects all have them, but those that are manually created
were missing them, so serializing the state into SQLAlchemy sessions failed.
