0 urgent 12 important 58 relevant 9 feasible 174 notes
relevance 3../test/test_primitives.cpp:202move this out to a test_enum_net test
relevance 3../src/file.cpp:484find out what error code is reported when the filesystem does not support hard links.
relevance 3../src/session_impl.cpp:3600also deduct force started checking torrents from checking_limit also deduct started inactive torrents from hard_limit
relevance 3../src/settings_pack.cpp:62write a unit test for settings_pack
relevance 3../src/upnp.cpp:88listen_interface is not used. It's meant to bind the broadcast socket. it would probably have to be changed to a vector of interfaces to bind to though, since the broadcast socket opens one socket per local interface by default
relevance 3../src/kademlia/get_item.cpp:202it would be nice to not have to spend so much time rendering the bencoded dict if logging is disabled
relevance 3../src/kademlia/get_item.cpp:226we don't support CAS errors here! we need a custom observer
relevance 3../src/kademlia/rpc_manager.cpp:84move this into it's own .cpp file
relevance 3../src/kademlia/traversal_algorithm.cpp:376it would be nice to not have to perform this loop if logging is disabled
relevance 3../include/libtorrent/peer_connection.hpp:1245factor this out into its own header and use it for UDP socket and maybe second_timer as well
relevance 3../include/libtorrent/peer_connection.hpp:1250if move semantics is supported, move the handler into this wrapper
relevance 3../include/libtorrent/torrent.hpp:1365factor out the links (as well as update_list() to a separate class that torrent can inherit)
relevance 2../test/test_piece_picker.cpp:277split this up into smaller tests (where we print_title)
relevance 2../src/alert.cpp:1444the salt here is allocated on the heap. It would be nice to allocate in in the stack_allocator
relevance 2../src/alert_manager.cpp:90keep a count of the number of threads waiting. Only if it's > 0 notify them
relevance 2../src/block_cache.cpp:1691turn these return values into enums returns -1: block not in cache -2: out of memory
relevance 2../src/escape_string.cpp:209this should probably be moved into string_util.cpp
relevance 2../src/file.cpp:508test this on a FAT volume to see what error we get!
relevance 2../src/http_tracker_connection.cpp:383returning a bool here is redundant. Instead this function should return the peer_entry
relevance 2../src/peer_connection.cpp:2340this should probably be based on time instead of number of request messages. For a very high throughput connection, 300 may be a legitimate number of requests to have in flight when getting choked
relevance 2../src/peer_connection.cpp:3051since we throw away the queue entry once we issue the disk job, this may happen. Instead, we should keep the queue entry around, mark it as having been requested from disk and once the disk job comes back, discard it if it has been cancelled. Maybe even be able to cancel disk jobs?
relevance 2../src/peer_connection.cpp:4709use a deadline_timer for timeouts. Don't rely on second_tick()! Hook this up to connect timeout as well. This would improve performance because of less work in second_tick(), and might let use remove ticking entirely eventually
relevance 2../src/peer_list.cpp:495it would be nice if there was a way to iterate over these torrent_peer objects in the order they are allocated in the pool instead. It would probably be more efficient
relevance 2../src/piece_picker.cpp:1974make the 2048 limit configurable
relevance 2../src/piece_picker.cpp:2583the first_block returned here is the largest free range, not the first-fit range, which would be better
relevance 2../src/piece_picker.cpp:3367it would be nice if this could be folded into lock_piece() the main distinction is that this also maintains the m_num_passed counter and the passed_hash_check member Is there ever a case where we call write filed without also locking the piece? Perhaps write_failed() should imply locking it.
relevance 2../src/session_impl.cpp:218find a better place for this function
relevance 2../src/session_impl.cpp:464is there a reason not to move all of this into init()? and just post it to the io_service?
relevance 2../src/session_impl.cpp:835if the DHT is enabled, it should probably be restarted here. maybe it should even be deferred to not be started until the client has had a chance to pass in the dht state
relevance 2../src/session_impl.cpp:1884the udp socket(s) should be using the same generic mechanism and not be restricted to a single one we should open a one listen socket for each entry in the listen_interfaces list
relevance 2../src/session_impl.cpp:1976use bind_to_device in udp_socket
relevance 2../src/session_impl.cpp:2002use bind_to_device in udp_socket
relevance 2../src/session_impl.cpp:3446make a list for torrents that want to be announced on the DHT so we don't have to loop over all torrents, just to find the ones that want to announce
relevance 2../src/storage.cpp:921is this risky? The upper layer will assume we have the whole file. Perhaps we should verify that at least the size of the file is correct
relevance 2../src/torrent.cpp:667post alert
relevance 2../src/torrent.cpp:3317this looks suspicious. Figure out why it makes sense to use the first IP in this list and leave a comment here
relevance 2../src/torrent.cpp:4822abort lookups this torrent has made via the session host resolver interface
relevance 2../src/torrent.cpp:4968the tracker login feature should probably be deprecated
relevance 2../src/torrent.cpp:7897if peer is a really good peer, maybe we shouldn't disconnect it perhaps this logic should be disabled if we have too many idle peers (with some definition of idle)
relevance 2../src/torrent.cpp:9834if residual is not used, remove it
relevance 2../src/tracker_manager.cpp:200some of these arguments could probably be moved to the tracker request itself. like the ip_filter and settings
relevance 2../src/udp_socket.cpp:734the udp_socket should really just be a single socket, and the session should support having more than one, just like with TCP sockets for now, just make bind failures non-fatal
relevance 2../src/udp_tracker_connection.cpp:83support authentication here. tracker_req().auth
relevance 2../src/ut_metadata.cpp:122if we were to initialize m_metadata_size lazily instead, we would probably be more efficient initialize m_metadata_size
relevance 2../src/utp_socket_manager.cpp:259we may want to take ec into account here. possibly close connections quicker
relevance 2../src/utp_stream.cpp:353it would be nice if not everything would have to be public here
relevance 2../src/web_peer_connection.cpp:622just make this peer not have the pieces associated with the file we just requested. Only when it doesn't have any of the file do the following
relevance 2../src/web_peer_connection.cpp:681create a mapping of file-index to redirection URLs. Use that to form URLs instead. Support to reconnect to a new server without destructing this peer_connection
relevance 2../src/kademlia/node.cpp:71make this configurable in dht_settings
relevance 2../src/kademlia/node.cpp:535it would be nice to have a bias towards node-id prefixes that are missing in the bucket
relevance 2../src/kademlia/node.cpp:625use the non deprecated function instead of this one
relevance 2../src/kademlia/node.cpp:958find_node should write directly to the response entry
relevance 2../src/kademlia/routing_table.cpp:116use the non deprecated function instead of this one
relevance 2../src/kademlia/routing_table.cpp:955move the lowest priority nodes to the replacement bucket
relevance 2../include/libtorrent/alert_types.hpp:1415should the alert baseclass have this object instead?
relevance 2../include/libtorrent/build_config.hpp:40instead of using a dummy function to cause link errors when incompatible build configurations are used, make the namespace name depend on the configuration, and have a using declaration in the headers to pull it into libtorrent.
relevance 2../include/libtorrent/enum_net.hpp:142this could be done more efficiently by just looking up the interface with the given name, maybe even with if_nametoindex()
relevance 2../include/libtorrent/heterogeneous_queue.hpp:56add emplace_back() version
relevance 2../include/libtorrent/peer_connection.hpp:1122rename this target queue size
relevance 2../include/libtorrent/piece_picker.hpp:598having 8 priority levels is probably excessive. It should probably be changed to 3 levels + dont-download
relevance 2../include/libtorrent/proxy_base.hpp:259use the resolver interface that has a built-in cache
relevance 2../include/libtorrent/session_handle.hpp:72the ip filter should probably be saved here too
relevance 2../include/libtorrent/session_settings.hpp:56this type is only used internally now. move it to an internal header and make this type properly deprecated.
relevance 2../include/libtorrent/socket_type.hpp:324it would be nice to use aligned_storage here when building on c++11
relevance 2../include/libtorrent/socks5_stream.hpp:135add async_connect() that takes a hostname and port as well
relevance 2../include/libtorrent/tracker_manager.hpp:278this class probably doesn't need to have virtual functions.
relevance 2../include/libtorrent/aux_/session_impl.hpp:1125the throttling of saving resume data could probably be factored out into a separate class
relevance 2../include/libtorrent/aux_/session_interface.hpp:137the IP voting mechanism should be factored out to its own class, not part of the session
relevance 2../include/libtorrent/aux_/session_interface.hpp:162remove this. There's already get_resolver()
relevance 2../include/libtorrent/aux_/session_interface.hpp:217factor out the thread pool for socket jobs into a separate class used to (potentially) issue socket write calls onto multiple threads
relevance 1../src/disk_io_thread.cpp:219it would be nice to have the number of threads be set dynamically
relevance 1../src/http_seed_connection.cpp:123in chunked encoding mode, this assert won't hold. the chunk headers should be subtracted from the receive_buffer_size
relevance 1../src/session_impl.cpp:5225report the proper address of the router as the source IP of this understanding of our external address, instead of the empty address
relevance 1../src/session_impl.cpp:6529we only need to do this if our global IPv4 address has changed since the DHT (currently) only supports IPv4. Since restarting the DHT is kind of expensive, it would be nice to not do it unnecessarily
relevance 1../src/torrent.cpp:1224make this depend on the error and on the filesystem the files are being downloaded to. If the error is no_space_left_on_device and the filesystem doesn't support sparse files, only zero the priorities of the pieces that are at the tails of all files, leaving everything up to the highest written piece in each file
relevance 1../src/torrent.cpp:7026save the send_stats state instead of throwing them away it may pose an issue when downgrading though
relevance 1../src/torrent.cpp:8231should disconnect all peers that have the pieces we have not just seeds. It would be pretty expensive to check all pieces for all peers though
relevance 1../include/libtorrent/ip_voter.hpp:124instead, have one instance per possible subnet, global IPv4, global IPv6, loopback, 192.168.x.x, 10.x.x.x, etc.
relevance 1../include/libtorrent/web_peer_connection.hpp:120if we make this be a disk_buffer_holder instead we would save a copy sometimes use allocate_disk_receive_buffer and release_disk_receive_buffer

relevance 0../test/test_metadata_extension.cpp:114it would be nice to test reversing which session is making the connection as well

relevance 0../test/test_resolve_links.cpp:80test files with different piece size (negative test)
relevance 0../test/test_resolve_links.cpp:83it would be nice to test resolving of more than just 2 files as well. like 3 single file torrents merged into one, resolving all 3 files.
relevance 0../test/test_resume.cpp:230test what happens when loading a resume file with both piece priorities and file priorities (file prio should take presedence)
relevance 0../test/test_resume.cpp:233make sure a resume file only ever contain file priorities OR piece priorities. Never both.
relevance 0../test/test_resume.cpp:236generally save
relevance 0../test/test_resume.cpp:648test all other resume flags here too. This would require returning more than just the torrent_status from test_resume_flags. Also http seeds and trackers for instance
relevance 0../test/test_ssl.cpp:378test using a signed certificate with the wrong info-hash in DN
relevance 0../test/test_ssl.cpp:476also test using a hash that refers to a valid torrent but that differs from the SNI hash
relevance 0../test/test_timestamp_history.cpp:54test the case where we have > 120 samples (and have the base delay actually be updated)
relevance 0../test/test_timestamp_history.cpp:55test the case where a sample is lower than the history entry but not lower than the base
relevance 0../test/test_torrent.cpp:135wait for an alert rather than just waiting 10 seconds. This is kind of silly
relevance 0../test/test_torrent_info.cpp:155test remap_files
relevance 0../test/test_torrent_info.cpp:156merkle torrents. specifically torrent_info::add_merkle_nodes and torrent with "root hash"

relevance 0../test/test_transfer.cpp:297factor out the disk-full test into its own unit test
relevance 0../test/test_upnp.cpp:108store the log and verify that some key messages are there
relevance 0../test/web_seed_suite.cpp:369file hashes don't work with the new torrent creator reading async
relevance 0../src/block_cache.cpp:959it's somewhat expensive to iterate over this linked list. Presumably because of the random access of memory. It would be nice if pieces with no evictable blocks weren't in this list
relevance 0../src/block_cache.cpp:1023this should probably only be done every n:th time
relevance 0../src/block_cache.cpp:1778create a holder for refcounts that automatically decrement
relevance 0../src/bt_peer_connection.cpp:679this could be optimized using knuth morris pratt
relevance 0../src/bt_peer_connection.cpp:2249if we're finished, send upload_only message
relevance 0../src/choker.cpp:336optimize this using partial_sort or something. We don't need to sort the entire list
relevance 0../src/choker.cpp:339make the comparison function a free function and move it into this cpp file
relevance 0../src/choker.cpp:344make configurable
relevance 0../src/choker.cpp:358make configurable
relevance 0../src/create_torrent.cpp:285this should probably be optional
relevance 0../src/disk_buffer_pool.cpp:319perhaps we should sort the buffers here?
relevance 0../src/disk_io_thread.cpp:884it would be nice to optimize this by having the cache pieces also ordered by
relevance 0../src/disk_io_thread.cpp:927instead of doing a lookup each time through the loop, save cached_piece_entry pointers with piece_refcount incremented to pin them
relevance 0../src/disk_io_thread.cpp:1106instead of doing this. pass in the settings to each storage_interface call. Each disk thread could hold its most recent understanding of the settings in a shared_ptr, and update it every time it wakes up from a job. That way each access to the settings won't require a mutex to be held.
relevance 0../src/disk_io_thread.cpp:1134a potentially more efficient solution would be to have a special queue for retry jobs, that's only ever run when a job completes, in any thread. It would only work if counters::num_running_disk_jobs > 0
relevance 0../src/disk_io_thread.cpp:1148it should clear the hash state even when there's an error, right?
relevance 0../src/disk_io_thread.cpp:1849maybe the tailqueue_iterator should contain a pointer-pointer instead and have an unlink function
relevance 0../src/disk_io_thread.cpp:2111this is potentially very expensive. One way to solve it would be to have a fence for just this one piece.
relevance 0../src/disk_io_thread.cpp:2373we should probably just hang the job on the piece and make sure the hasher gets kicked
relevance 0../src/disk_io_thread.cpp:2440introduce a holder class that automatically increments and decrements the piece_refcount
relevance 0../src/disk_io_thread.cpp:2688it would be nice to not have to lock the mutex every turn through this loop
relevance 0../src/file_progress.cpp:136it would be nice to not depend on alert_manager here
relevance 0../src/http_tracker_connection.cpp:185support this somehow
relevance 0../src/metadata_transfer.cpp:358this is not safe. The torrent could be unloaded while we're still sending the metadata
relevance 0../src/packet_buffer.cpp:180use compare_less_wrap for this comparison as well
relevance 0../src/part_file.cpp:252what do we do if someone is currently reading from the disk from this piece? does it matter? Since we won't actively erase the data from disk, but it may be overwritten soon, it's probably not that big of a deal
relevance 0../src/part_file.cpp:353instead of rebuilding the whole file header and flushing it, update the slot entries as we go
relevance 0../src/peer_connection.cpp:512it would be neat to be able to print this straight into the alert's stack allocator
relevance 0../src/peer_connection.cpp:1013this should be the global download rate
relevance 0../src/peer_connection.cpp:3290sort the allowed fast set in priority order
relevance 0../src/peer_connection.cpp:6092The stats checks can not be honored when authenticated encryption is in use because we may have encrypted data which we cannot authenticate yet
relevance 0../src/piece_picker.cpp:2048this could probably be optimized by incrementally calling partial_sort to sort one more element in the list. Because chances are that we'll just need a single piece, and once we've picked from it we're done. Sorting the rest of the list in that case is a waste of time.
relevance 0../src/piece_picker.cpp:2553when expanding pieces for cache stripe reasons, the !downloading condition doesn't make much sense
relevance 0../src/session_impl.cpp:520there's no rule here to make uTP connections not have the global or local rate limits apply to it. This used to be the default.
relevance 0../src/session_impl.cpp:1555it would be nice to reserve() these vectors up front
relevance 0../src/session_impl.cpp:1798instead of having a special case for this, just make the default listen interfaces be "0.0.0.0:6881,[::1]:6881" and use the generic path. That would even allow for not listening at all.
relevance 0../src/session_impl.cpp:2687should this function take a shared_ptr instead?
relevance 0../src/session_impl.cpp:3035have a separate list for these connections, instead of having to loop through all of them
relevance 0../src/session_impl.cpp:3068this should apply to all bandwidth channels
relevance 0../src/session_impl.cpp:3791use a lower limit than m_settings.connections_limit to allocate the to 10% or so of connection slots for incoming connections
relevance 0../src/session_impl.cpp:3941post a message to have this happen immediately instead of waiting for the next tick
relevance 0../src/session_impl.cpp:4324it might be a nice feature here to limit the number of torrents to send in a single update. By just posting the first n torrents, they would nicely be round-robined because the torrent lists are always pushed back. Perhaps the status_update_alert could even have a fixed array of n entries rather than a vector, to further improve memory locality.
relevance 0../src/session_impl.cpp:4530this logic could probably be less spaghetti looking by being moved to a function with early exits
relevance 0../src/storage.cpp:731make this more generic to not just work if files have been renamed, but also if they have been merged into a single file for instance maybe use the same format as .torrent files and reuse some code from torrent_info
relevance 0../src/storage.cpp:1062if everything moves OK, except for the partfile we currently won't update the save path, which breaks things. it would probably make more sense to give up on the partfile
relevance 0../src/string_util.cpp:60warning C4146: unary minus operator applied to unsigned type, result still unsigned
relevance 0../src/torrent.cpp:97factor out cache_status to its own header
relevance 0../src/torrent.cpp:458if the existing torrent doesn't have metadata, insert the metadata we just downloaded into it.
relevance 0../src/torrent.cpp:608if the existing torrent doesn't have metadata, insert the metadata we just downloaded into it.
relevance 0../src/torrent.cpp:1534is verify_peer_cert called once per certificate in the chain, and this function just tells us which depth we're at right now? If so, the comment makes sense. any certificate that isn't the leaf (i.e. the one presented by the peer) should be accepted automatically, given preverified is true. The leaf certificate need to be verified to make sure its DN matches the info-hash
relevance 0../src/torrent.cpp:1942instead of creating the picker up front here, maybe this whole section should move to need_picker()
relevance 0../src/torrent.cpp:2016this could be optimized by looking up which files are complete and just look at those
relevance 0../src/torrent.cpp:2032this could be optimized by looking up which files are complete and just look at those
relevance 0../src/torrent.cpp:2199there may be peer extensions relying on the torrent extension still being alive. Only do this if there are no peers. And when the last peer is disconnected, if the torrent is unloaded, clear the extensions m_extensions.clear();
relevance 0../src/torrent.cpp:2884this pattern is repeated in a few places. Factor this into a function and generalize the concept of a torrent having a dedicated listen port
relevance 0../src/torrent.cpp:3669add one peer per IP the hostname resolves to
relevance 0../src/torrent.cpp:4601update suggest_piece?
relevance 0../src/torrent.cpp:4744really, we should just keep the picker around in this case to maintain the availability counters
relevance 0../src/torrent.cpp:6734make this more generic to not just work if files have been renamed, but also if they have been merged into a single file for instance maybe use the same format as .torrent files and reuse some code from torrent_info The mapped_files needs to be read both in the network thread and in the disk thread, since they both have their own mapped files structures which are kept in sync
relevance 0../src/torrent.cpp:6858if this is a merkle torrent and we can't restore the tree, we need to wipe all the bits in the have array, but not necessarily we might want to do a full check to see if we have all the pieces. This is low priority since almost no one uses merkle torrents
relevance 0../src/torrent.cpp:7083make this more generic to not just work if files have been renamed, but also if they have been merged into a single file for instance. using file_base
relevance 0../src/torrent.cpp:9255add a flag to ignore stats, and only care about resume data for content. For unchanged files, don't trigger a load of the metadata just to save an empty resume data file
relevance 0../src/torrent.cpp:10859instead of resorting the whole list, insert the peers directly into the right place
relevance 0../src/torrent_peer.cpp:179how do we deal with our external address changing?
relevance 0../src/udp_socket.cpp:288it would be nice to detect this on posix systems also
relevance 0../src/udp_socket.cpp:788use the system resolver_interface here
relevance 0../src/ut_metadata.cpp:315we really need to increment the refcounter on the torrent while this buffer is still in the peer's send buffer
