Sequential download

[Banou26]

libtorrent version (or branch): Python 2.0.7 platform/architecture: Win 64 21H2

It seems to me that the sequential download mode doesn't work. I have tried a few ways to set my torrent as sequential download with none of them effectively working

self.session.apply_settings({
    'auto_sequential': True
})

params.flags |= lt.add_torrent_params_flags_t.flag_sequential_download

handle.set_sequential_download(True)

All of these don't seem to make my torrents download sequentially, ~~i add my torrents with params.flags &= ~lt.add_torrent_params_flags_t.flag_auto_managed as i don't want them managed (it's for a server) as the managed mode has some side effects(prioritize some torrents while leaving others) as auto management suggest, that aren't suited for my server implementation.~~

~~Is the sequential download only working for auto managed torrents?~~

For example, with a torrent set as sequential download, i am getting random downloads without priority on the beginning at all, even though i know sequential download doesn't provides any guarantees that they will be in order, it should at least be a little bit sequential, which in my case isn't.

Should i rely entirely on piece_priority and set_piece_deadline instead?

Edit: Just tried with the auto managed mode, the sequential flag doesn't seem to make the torrents download sequentially either

I cannot reproduce this. I tested this in client_test. it uses

h.set_flags(~ts.flags, lt::torrent_flags::sequential_download);

For some reason trying in a clean repo sequential download works properly, i'm guessing the issue is the wheel i installed for typings that breaks it, is it possible to get python typings for future releases?

[arvidn]

is it possible to get python typings for future releases?

I don't know how to do that, but patches are welcome!
