From 3daee2c66cbf752b9e6e49b99492b8c1914a4a58 Mon Sep 17 00:00:00 2001 From: Feross Aboukhadijeh Date: Wed, 20 Apr 2016 23:10:32 -0700 Subject: BREAKING: Major cleanup ### Added - `client.listening` property to signal whether TCP server is listening for incoming connections. ### Changed - Merged `Swarm` class into `Torrent` object. Properties on `torrent.swarm` (like `torrent.swarm.wires`) now exist on `torrent` (e.g. `torrent.wires`). - `torrent.addPeer` can no longer be called before the `infoHash` event has been emitted. - Remove `torrent.on('listening')` event. Use `client.on('listening')` instead. - Remove support from `TCPPool` for listening on multiple ports. This was not used by WebTorrent and just added complexity. There is now a single `TCPPool` instance for the whole WebTorrent client. - Deprecate: Do not use `client.download()` anymore. Use `client.add()` instead. - Deprecate: Do not use `torrent.swarm` anymore. Use `torrent` instead. ### Fixed - When there is a `torrent.on('error')` listener, don't also emit `client.on('error')`. - Do not return existing torrent object when duplicate torrent is added. Fire an `'error'` event instead. - Memory leak of `Torrent` object caused by `RarityMap` - Memory leak of `Torrent` object caused by `TCPPool` - `client.ratio` and `torrent.ratio` are now calculated as `uploaded / received` instead of `uploaded / downloaded`. --- test/node/download-private-dht.js | 2 +- test/node/download-webseed-magnet.js | 12 ++-- test/node/duplicates.js | 80 ---------------------- test/node/extensions.js | 2 +- test/node/metadata.js | 4 +- test/node/swarm-basic.js | 120 ++++++++++++++++----------------- test/node/swarm-reconnect.js | 124 +++++++++++++++++------------------ test/node/swarm-timeout.js | 100 ++++++++++++++-------------- 8 files changed, 182 insertions(+), 262 deletions(-) delete mode 100644 test/node/duplicates.js (limited to 'test/node') diff --git a/test/node/download-private-dht.js b/test/node/download-private-dht.js index 023f7ff..0f1a984 100644 --- a/test/node/download-private-dht.js +++ b/test/node/download-private-dht.js @@ -35,7 +35,7 @@ test('private torrent should not use DHT', function (t) { }) client.on('torrent', function () { -
