5 -TODO

5 +We're happy to release go-ipfs 0.4.20. This release includes some critical

6 +performance and stability fixes so all users should upgrade ASAP.

7 +

8 +This is also the first release to use go modules instead of GX. While GX has

9 +been a great way to dogfood an IPFS-based package manager, building and

10 +maintaining a custom package manager is a _lot_ of work and we haven't been able

11 +to dedicate enough time to bring the user experience of gx to an acceptable

12 +level. You can read [#5850](https://github.com/ipfs/go-ipfs/issues/5850) for

13 +some discussion on this matter.

14 +

15 +### Docker

16 +

17 +As of this release, it's now much easier to run arbitrary IPFS commands within

18 +the docker container:

19 +

20 +```bash

21 +> docker run ipfs/go-ipfs config profile apply server # apply the server profile

22 +> docker run ipfs/go-ipfs # start the daemon

23 +```

24 +

25 +This release also [reverts](https://github.com/ipfs/go-ipfs/pull/6040) a change that

26 +caused some significant trouble in 0.4.19. If you've been running into Docker

27 +permission errors in 0.4.19, please upgrade.

28 +

29 +### WebUI

30 +

31 +This release contains a major

32 +[WebUI](https://github.com/ipfs-shipyard/ipfs-webui) release with some

33 +significant improvements to the file browser and new opt-in, privately hosted,

34 +anonymous usage analytics.

35 +

36 +### Commands

37 +

38 +As usual, we've made several changes and improvements to our commands. The most

39 +notable changes are listed in this section.

40 +

41 +#### New: `ipfs version deps`

42 +

43 +This release includes a new command, `ipfs version deps`, to list all

44 +dependencies (with versions) of the current go-ipfs build. This should make it

45 +easy to tell exactly how go-ipfs was built when tracking down issues.

46 +

47 +#### New: `ipfs add URL`

48 +

49 +The `ipfs add` command has gained support for URLs. This means you can:

50 +

51 +1. Add files with `ipfs add URL` instead of downloading the file first.

52 +2. Replace all uses of the `ipfs urlstore` command with a call to `ipfs add

53 + --nocopy`. The `ipfs urlstore` command will be deprecated in a future

54 + release.

55 +

56 +

57 +#### Changed: `ipfs swarm connect`

58 +

59 +The `ipfs swarm connect` command has a few new features:

60 +

61 +It now marks the newly created connection as "important". This should ensure

62 +that the connection manager won't come along later and close the connection if

63 +it doesn't think it's being used.

64 +

65 +It can now resolve `/dnsaddr` addresses that _don't_ end in a peer ID. For

66 +example, you can now run `ipfs swarm connect /dnsaddr/bootstrap.libp2p.io` to

67 +connect to one of the bootstrap peers at random. NOTE: This is could connect you

68 +to an _arbitrary_ peer as DNS is not secure (by default). Please do not rely on

69 +this except for testing or unless you know what you're doing.

70 +

71 +Finally, `ipfs swarm connect` now returns _all_ errors on failure. This should

72 +make it much easier to debug connectivity issues. For example, one might see an

73 +error like:

74 +

75 +```

76 +Error: connect QmYou failure: dial attempt failed: 6 errors occurred:

77 + * <peer.ID Qm*Me> --> <peer.ID Qm*You> (/ip4/127.0.0.1/tcp/4001) dial attempt failed: dial tcp4 127.0.0.1:4001: connect: connection refused

78 + * <peer.ID Qm*Me> --> <peer.ID Qm*You> (/ip6/::1/tcp/4001) dial attempt failed: dial tcp6 [::1]:4001: connect: connection refused

79 + * <peer.ID Qm*Me> --> <peer.ID Qm*You> (/ip6/2604::1/tcp/4001) dial attempt failed: dial tcp6 [2604::1]:4001: connect: network is unreachable

80 + * <peer.ID Qm*Me> --> <peer.ID Qm*You> (/ip6/2602::1/tcp/4001) dial attempt failed: dial tcp6 [2602::1]:4001: connect: network is unreachable

81 + * <peer.ID Qm*Me> --> <peer.ID Qm*You> (/ip4/150.0.1.2/tcp/4001) dial attempt failed: dial tcp4 0.0.0.0:4001->150.0.1.2:4001: i/o timeout

82 + * <peer.ID Qm*Me> --> <peer.ID Qm*You> (/ip4/200.0.1.2/tcp/4001) dial attempt failed: dial tcp4 0.0.0.0:4001->200.0.1.2:4001: i/o timeout

83 +```

84 +

85 +#### Changed: `ipfs bitswap stat`

86 +

87 +`ipfs bitswap stat` no longer lists bitswap partners unless the `-v` flag is

88 +passed. That is, it will now return:

89 +

90 +```

91 +> ipfs bitswap stat

92 +bitswap status

93 + provides buffer: 0 / 256

94 + blocks received: 0

95 + blocks sent: 79

96 + data received: 0

97 + data sent: 672706

98 + dup blocks received: 0

99 + dup data received: 0 B

100 + wantlist [0 keys]

101 + partners [197]

102 +```

103 +

104 +Instead of:

105 +

106 +```

107 +> ipfs bitswap stat -v

108 +bitswap status

109 + provides buffer: 0 / 256

110 + blocks received: 0

111 + blocks sent: 79

112 + data received: 0

113 + data sent: 672706

114 + dup blocks received: 0

115 + dup data received: 0 B

116 + wantlist [0 keys]

117 + partners [203]

120 + QmNgSVpgZVEd41pBX6DyCaHRof8UmUJLqQ3XH2qNL9xLvN

121 + ... omitting 200 lines ...

122 +```

123 +

124 +#### Changed: `ipfs repo stat --human`

125 +

126 +The `--human` flag in the `ipfs repo stat` command now intelligently picks a

127 +size unit instead of always using MiB.

128 +

129 +#### Changed: `ipfs resolve` (`ipfs dns`, `ipfs name resolve`)

130 +

131 +All of the resolve commands now:

132 +

133 +1. Resolve _recursively_ (up to 32 steps) by default to better match user

134 + expectations (these commands used to be non-recursive by default). To turn

135 + recursion off, pass `-r false`.

136 +2. When resolving non-recursively, these commands no longer fail when partially

137 + resolving a name. Instead, they simply return the intermediate result.

138 +

139 +#### Changed: `ipfs files flush`

140 +

141 +The `ipfs files flush` command now returns the CID of the flushed file.

142 +

143 +### Performance And Reliability

144 +

145 +This release has the usual collection of performance and reliability

146 +improvements.

147 +

148 +#### Badger Memory Usage

149 +

150 +Those of you using the badger datastore should notice reduced memory usage in

151 +this release due to some upstream changes. Badger still uses significantly more

152 +memory than the default datastore configuration but this will hopefully continue

153 +to improve.

154 +

155 +#### Bitswap

156 +

157 +We fixed some critical CPU utilization regressions in bitswap for this release.

158 +If you've been noticing CPU _regressions_ in go-ipfs 0.4.19, especially when

159 +running a public gateway, upgrading to 0.4.20 will likely fix them.

160 +

161 +#### Relays

162 +

163 +After AutoRelay was introduced in go-ipfs 0.4.19, the number of peers connecting

164 +through relays ski-rocketed to over 120K concurrent peers. This highlighted some

165 +performance issues that we've now fixed in this release. Specifically:

166 +

167 +* We've significantly reduced the amount of memory allocated per-peer.

168 +* We've fixed a bug where relays might, in rare cases, try to actively dial a

169 + peer to relay traffic. By default, relays only forward traffic between peers

170 + already connected to the relay.

171 +* We've fixed quite a number of performance issues that only show up when

172 + rapidly forming new connections. This will actually help _all_ nodes but will

173 + especially help relays.

174 +

175 +If you've enabled relays in go-ipfs 0.4.19 and it hasn't burned down your

176 +machine yet, this release should improve things significantly. However, relays

177 +are still under heavy load so running an open relay will continue to be resource

178 +intensive.

179 +

180 +We're continuing to investigate this issue and have a few more patches on the

181 +way that, unfortunately, won't make it into this release.

182 +

183 +#### Panics

184 +

185 +We've fixed two notable panics in this release:

186 +

187 +* We've fixed a frequent panic in the DHT.

188 +* We've fixed an occasional panic in the experimental QUIC transport.

189 +

190 +### Content Routing

191 +

192 +IPFS announces and finds content by sending and retrieving content routing

193 +("provider") records to and from the DHT. Unfortunately, sending out these

194 +records can be quite resource intensive.

195 +

196 +This release has two changes to alleviate this: a reduced number of initial

197 +provide workers and a persistent provider queue.

198 +

199 +We've reduced the number of parallel initial provide workers (workers that send

200 +out provider records when content is initially added to go-ipfs) from 512 to 6.

201 +Each provide request (currently, due to some issues in our DHT) tries to

202 +establish hundreds of connections, significantly impacting the performance of

203 +go-ipfs and [crashing some

204 +routers](https://github.com/ipfs/go-ipfs/issues/3320).

205 +

206 +We've introduced a new persistent provider queue for files added via `ipfs add`

207 +and `ipfs pin add`. When new directory trees are added to go-ipfs, go-ipfs will

208 +add the root/final CID to this queue. Then, in the background, go-ipfs will walk

209 +the queue, sequentially sending out provider records for each CID.

210 +

211 +This ensures that root CIDs are sent out as soon as possible and are sent even

212 +when files are added when the go-ipfs daemon isn't running.

213 +

214 +By example, let's add a directory tree to go-ipfs:

215 +

216 +```bash

217 +> # We're going to do this in "online" mode first so let's start the daemon.

218 +> ipfs daemon &

219 +...

220 +Daemon is ready

221 +> # Now, we're going to create a directory to add.

222 +> mkdir foo

223 +> for i in {0..1000}; do echo do echo $i > foo/$i; done

224 +> # finally, we're going to add it.

225 +> ipfs add -r foo

226 +added QmUQcSjQx2bg4cSe2rUZyQi6F8QtJFJb74fWL7D784UWf9 foo/0

227 +...

228 +added QmQac2chFyJ24yfG2Dfuqg1P5gipLcgUDuiuYkQ5ExwGap foo/990

229 +added QmQWwz9haeQ5T2QmQeXzqspKdowzYELShBCLzLJjVa2DuV foo/991

230 +added QmQ5D4MtHUN4LTS4n7mgyHyaUukieMMyCfvnzXQAAbgTJm foo/992

231 +added QmZq4n4KRNq3k1ovzxJ4qdQXZSrarfJjnoLYPR3ztHd7EY foo/993

232 +added QmdtrsuVf8Nf1s1MaSjLAd54iNqrn1KN9VoFNgKGnLgjbt foo/994

233 +added QmbstvU9mnW2hsE94WFmw5WbrXdLTu2Sf9kWWSozrSDscL foo/995

234 +added QmXFd7f35gAnmisjfFmfYKkjA3F3TSpvUYB9SXr6tLsdg8 foo/996

235 +added QmV5BxS1YQ9V227Np2Cq124cRrFDAyBXNMqHHa6kpJ9cr6 foo/997

236 +added QmcXsccUtwKeQ1SuYC3YgyFUeYmAR9CXwGGnT3LPeCg5Tx foo/998

237 +added Qmc4mcQcpaNzyDQxQj5SyxwFg9ZYz5XBEeEZAuH4cQirj9 foo/999

238 +added QmXpXzUhcS9edmFBuVafV5wFXKjfXkCQcjAUZsTs7qFf3G foo

239 +```

240 +

241 +In 0.4.19, we would have sent out provider records for files `foo/{0..1000}`

242 +_before_ sending out a provider record for `foo`. If you were ask a friend to

243 +download /ipfs/QmUQcSjQx2bg4cSe2rUZyQi6F8QtJFJb74fWL7D784UWf9, they would

244 +(baring other issues) be able to find it pretty quickly as this is the first CID

245 +you'll have announced to the network. However, if you ask your friend to

246 +download /ipfs/QmXpXzUhcS9edmFBuVafV5wFXKjfXkCQcjAUZsTs7qFf3G/0, they'll have to

247 +wait for you to finish telling the network about every file in `foo` first.

248 +

249 +In 0.4.20, we _immediately_ tell the network about

250 +`QmXpXzUhcS9edmFBuVafV5wFXKjfXkCQcjAUZsTs7qFf3G` (the `foo` directory) as soon

251 +as we finish adding the directory to go-ipfs _without_ waiting to finish

252 +announcing `foo/{0..1000}`. This is especially important in this release

253 +because we've drastically reduced the number of provide workers.

254 +

255 +The second benefit is that this queue is persistent. That means go-ipfs won't

256 +forget to send out this record, even if it was offline when the content was

257 +initially added. NOTE: go-ipfs _does_ continuously _re_-send provider records in

258 +the background twice a day, it just might be a while before it gets around to

259 +sending one out any specific one.

260 +

261 +### Bitswap

262 +

263 +Bitswap now periodically re-sends its wantlist to connected peers. This should

264 +help work around some race conditions we've seen in bitswap where one node wants

265 +a block but the other doesn't know for some reason.

266 +

267 +You can track this issue here: https://github.com/ipfs/go-ipfs/issues/5183.

268 +

269 +### Improved NAT Traversal

270 +

271 +While NATs are still p2p enemy #1, this release includes slightly improved

272 +support for traversing them.

273 +

274 +Specifically, this release now:

275 +

276 +1. Better detects the "gateway" NAT, even when multiple devices on the network

277 + _claim_ to be NATs.

278 +2. Better guesses the external IP address when port mapping, even when the

279 + gateway lies.

280 +

281 +### Reduced AutoRelay Boot Time

282 +

283 +The experimental AutoRelay feature can now detect NATs _much_ faster as we've

284 +reduced initial NAT detection delay to 15 seconds. There's still room for

285 +improvement but this should make nodes that have enabled this feature dialable

286 +earlier on start.

287 +
