* fix: update `date_done_` as long as the torrent is done
* fix: `mark_change()` should be called as long as torrent state changes
* chore: remove redundant completeness update in `tr_torrent::start_in_session_thread()`
* fix: log whenever torrent state changes
* chore: add comment to explain `recent_change`
* chore: housekeeping
* fix: recover torrents with missing date done
* fix: allow connection between seeds when pex is enabled
* chore: add comment to explain `tr_peerMsgs::on_torrent_got_metainfo()`
* refactor: remove `tr_swarm::mark_peer_as_seed()`
* fix: update seed flag in response to BT msgs
Regression from 81a42c6bb6
* chore: remove redundant code to update peer seed flag
* refactor: inc failure count if there were no piece data exchanged
* fix: save information from ltep handshake
* refactor: rename `tr_peerIo::is_seed_` to disambiguate
* fix: add instead of set pex flags when adding non-pex and non-resume peers
* fix: don't mark peer as connectable on getting ltep port msg
By BEP-11's definition, this flag is only set for peers whom we successfully initiated an outgoing connection with.
* refactor: set holepunch flag when we get it from ltep handshake
* fix: only accept positive `reqq` in ltep handshake
* refactor: handle encryption preference in `tr_peer_info`
* refactor: prefer own value for utp support
* refactor: make `tr_peer_info::from_first_` const
* refactor: handle holepunch support in `tr_peer_info`
* fix: parse metadata size only if we have a valid extention id for metadata xfer
* refactor: remove `tr_peer_info::add_pex_flags()` as it's no longer needed
* fix: correctly handle holepunch support when there is no `m` key in ltep handshake
* fix: distinguish between upload only and seed
Say we just connected to a partial seed, the peer sends an ltep handshake that has the `upload_only` key, then a BT `Bitfield` message:
Without this change, the pex seed flag would be set when parsing the ltep handshake, then immediately unset when parsing the `Bitfield` message.
We don't want that.
* fix: don't update `tr_peer_info::is_seed_` when merging peer info objects
* perf: priority in peer candidate score need 2 bits only
* fix: prefer to connect to downloading peers
Regression from c867f00153
* chore: add TODO for C++20 opportunity
* refactor: don't filter out peers without `ADDED_F_CONNECTABLE`
revert change from a2849219f7
* refactor: move peer state updates out of peermgr code

* refactor: remove last byte special case in `tr_block_info::byte_loc()`
* fix: handle 0-byte file at the end of torrent in fpm
* test: modify test for 0-byte file at the end of torrent
* fix: handle 0-byte file at the end of torrent in `block_span_for_file`
* Remove `tr_file_move_strict()`, add param to `tr_file_move()` instead
Also restores proper `local_error` logic to handle null error param.
* Remove unused `moved_files` logic
* Rename the callback type and params to match rename decls
* Add torrent ID param to torrent removal callback
* Remove mutex from torrent removal callback
Torrent IDs aren't reused during the lifetime of the session.
* Move main removal callback logic into a separate method
* Do not remove torrent if trashing files failed.
Instead, stop the torrent and sets an error.
* Fixing GTK interface with new file removal behavior.
* C++17 compliant.
* Reverting unrelated change.
* Avoiding allocating unecessary objects.
* Easy review fixes.
* Fixing merge error.
* Adding result callback to tr_torrentRemove().
Using the new callback in Gtk GUI to decide when to remove it from the
interface.
* Reducing indentation level and making the function more readable.
* Using existing Session RefPtr.
* Notifying the client before freeing the torrent in the session.
* Addressing comments and synchronizing callback.
* Moving include.
* Fix constness issue reported by clang-tidy
The crash will happen if the following series of events happened:
1. Torrent verification starts for a `tr_torrent` object.
2. The session thread starts executing `tr_torrentFreeInSessionThread()`, about to free this `tr_torrent` object.
3. `tr_torrent::VerifyMediator::on_verify_done()` queues a lambda that captures a pointer to the `tr_torrent` object.
4. The `tr_torrent` object is freed.
5. The session thread executes the lambda from Step 3, and crashes when dereferencing the dangling `tr_torrent` pointer.
* fix: queue torrent verification as soon as metadata complete
* fix: avoid heap-use-after-free in `tr_peerMsgsImpl::process_peer_message()`
