go-ipfs changelog

0.4.12-rc1 2017-10-26

0.4.11 2017-09-14

Ipfs 0.4.11 is a larger release that brings many long-awaited features and performance improvements. These include new datastore options, more efficient bitswap transfers, greatly improved resource consumption, circuit relay support, ipld plugins, and more! Take a look at the full changelog below for a detailed list of every change.

The ipfs datastore has, until now, been a combination of leveldb and a custom git-like storage backend called 'flatfs'. This works well enough for the average user, but different ipfs usecases demand different backend configurations. To address this, we have changed the configuration file format for datastores to be a modular way of specifying exactly how you want the datastore to be structured. You will now be able to configure ipfs to use flatfs, leveldb, badger, an in-memory datastore, and more to suit your needs. See the new datastore documentation for more information.

Bitswap received some much needed attention during this release cycle. The concept of 'Bitswap Sessions' allows bitswap to associate requests for different blocks to the same underlying session, and from that infer better ways of requesting that data. In more concrete terms, parts of the ipfs codebase that take advantage of sessions (currently, only ipfs pin add) will cause much less extra traffic than before. This is done by making optimistic guesses about which nodes might be providing given blocks and not sending wantlist updates to every connected bitswap partner, as well as searching the DHT for providers less frequently. In future releases we will migrate over more ipfs commands to take advantage of bitswap sessions. As nodes update to this and future versions, expect to see idle bandwidth usage on the ipfs network go down noticably.

The never ending effort to reduce resource consumption had a few important updates this release. First, the bitswap sessions changes discussed above will help with improving bandwidth usage. Aside from that there are two important libp2p updates that improved things significantly. The first was a fix to a bug in the dial limiter code that was causing it to not limit outgoing dials correctly. This resulted in ipfs running out of file descriptors very frequently (as well as incurring a decent amount of excess outgoing bandwidth), this has now been fixed. Users who previously received "too many open files" errors should see this much less often in 0.4.11. The second change was a memory leak in the DHT that was identified and fixed. Streams being tracked in a map in the DHT weren't being cleaned up after the peer disconnected leading to the multiplexer session not being cleaned up properly. This issue has been resolved, and now memory usage appears to be stable over time. There is still a lot of work to be done improving memory usage, but we feel this is a solid victory.

It is often said that NAT traversal is the hardest problem in peer to peer technology, we tend to agree with this. In an effort to provide a more ubiquitous p2p mesh, we have implemented a relay mechanism that allows willing peers to relay traffic for other peers who might not otherwise be able to communicate with each other. This feature is still pretty early, and currently users have to manually connect through a relay. The next step in this endeavour is automatic relaying, and research for this is currently in progress. We expect that when it lands, it will improve the perceived performance of ipfs by spending less time attempting connections to hard to reach nodes. A short guide on using the circuit relay feature can be found here.

The last feature we want to highlight (but by no means the last feature in this release) is our new plugin system. There are many different workflows and usecases that ipfs should be able to support, but not everyone wants to be able to use every feature. We could simply merge in all these features, but that causes problems for several reasons: first off, the size of the ipfs binary starts to get very large very quickly. Second, each of these different pieces needs to be maintained and updated independently, which would cause significant churn in the codebase. To address this, we have come up with a system that allows users to install plugins to the vanilla ipfs daemon that augment its capabilities. The first of these plugins are a git plugin that allows ipfs to natively address git objects and an ethereum plugin that lets ipfs ingest and operate on all ethereum blockchain data. Soon to come are plugins for the bitcoin and zcash data formats. In the future, we will be adding plugins for other things like datastore backends and specialized libp2p network transports. You can read more on this topic in Plugin docs

In order to simplify its integration with fs-repo-migrations, we've switched the ipfs/go-ipfs docker image from a musl base to a glibc base. For most users this will not be noticable, but if you've been building your own images based off this image, you'll have to update your dockerfile. We recommend a multi-stage dockerfile, where the build stage is based off of a regular Debian or other glibc-based image, and the assembly stage is based off of the ipfs/go-ipfs image, and you copy build artifacts from the build stage to the assembly stage. Note, if you are using the docker image and see a deprecation message, please update your usage. We will stop supporting the old method of starting the dockerfile in the next release.

Finally, I would like to thank all of our contributors, users, supporters, and friends for helping us along the way. Ipfs would not be where it is without you.

0.4.10 - 2017-06-27

Ipfs 0.4.10 is a patch release that contains several exciting new features, bugfixes and general improvements. Including new commands, easier corruption recovery, and a generally cleaner codebase.

The ipfs pin command has two new subcommands, verify and update. ipfs pin verify is used to scan the repo for pinned object graphs and check their integrity. Any issues are reported back with helpful error text to make error recovery simpler. This subcommand was added to help recover from datastore corruptions, particularly if using the experimental filestore and accidentally deleting tracked files. ipfs pin update was added to make the task of keeping a large, frequently changing object graph pinned. Previously users had to call ipfs pin rm on the old pin, and ipfs pin add on the new one. The 'new' ipfs pin add call would be very expensive as it would need to verify the entirety of the graph again. The ipfs pin update command takes shortcuts, portions of the graph that were covered under the old pin are assumed to be fine, and the command skips checking them.

Next up, we have finally implemented an ipfs shutdown command so users can shut down their ipfs daemons via the API. This is especially useful on platforms that make it difficult to control processes (Android, for example), and is also useful when needing to shut down a node remotely and you do not have access to the machine itself.

ipfs add has gained a new flag; the --hash flag allows you to select which hash function to use and we have given it the ability to select blake2b-256. This pushes us one step closer to shifting over to using blake2b as the default. Blake2b is significantly faster than sha2-256, and also is conjectured to provide superior security.

We have also finally implemented a very early (and experimental) ipfs p2p. This command and its subcommands will allow you to open up arbitrary streams to other ipfs peers through libp2p. The interfaces are a little bit clunky right now, but shouldn't get in the way of anyone wanting to try building a fully peer to peer application on top of ipfs and libp2p. For more info on this command, to ask questions, or to provide feedback, head over to the feedback issue for the command.

A few other subcommands and flags were added around the API, as well as many other requested improvements. See below for the full list of changes.

0.4.9 - 2017-04-30

Ipfs 0.4.9 is a maintenance release that contains several useful bugfixes and improvements. Notably, ipfs add has gained the ability to select which CID version will be output. The common ipfs hash that looks like this: QmRjNgF2mRLDT8AzCPsQbw1EYF2hDTFgfUmJokJPhCApYP is a multihash. Multihashes allow us to specify the hashing algorithm that was used to verify the data, but it doesn't give us any indication of what format that data might be. To address that issue, we are adding another couple of bytes to the prefix that will allow us to indicate the format of the data referenced by the hash. This new format is called a Content ID, or CID for short. The previous bare multihashes will still be fully supported throughout the entire application as CID version 0. The new format with the type information will be CID version 1. To give an example, the content referenced by the hash above is "Hello Ipfs!". That same content, in the same format (dag-protobuf) using CIDv1 is zb2rhkgXZVkT2xvDiuUsJENPSbWJy7fdYnsboLBzzEjjZMRoG.

CIDv1 hashes are supported in ipfs versions back to 0.4.5. Nodes running 0.4.4 and older will not be able to load content via CIDv1 and we recommend that they update to a newer version.

There are many other use cases for CIDs. Plugins can be written to allow ipfs to natively address content from any other merkletree based system, such as git, bitcoin, zcash and ethereum -- a few systems we've already started work on.

Aside from the CID flag, there were many other changes as noted below:

0.4.8 - 2017-03-29

Ipfs 0.4.8 brings with it several improvements, bugfixes, documentation improvements, and the long awaited directory sharding code.

Currently, when too many items are added into a unixfs directory, the object gets too large and you may experience issues. To pervent this problem, and generally make working really large directories more efficient, we have implemented a HAMT structure for unixfs. To enable this feature, run:

ipfs config --json Experimental.ShardingEnabled true

And restart your daemon if it was running.

Note: With this setting enabled, the hashes of any newly added directories will be different than they previously were, as the new code will use the sharded HAMT structure for all directories. Also, nodes running ipfs 0.4.7 and earlier will not be able to access directories created with this option.

That said, please do give it a try, let us know how it goes, and then take a look at all the other cool things added in 0.4.8 below.

0.4.7 - 2017-03-15

Ipfs 0.4.7 contains several exciting new features! First off, The long awaited filestore feature has been merged, allowing users the option to not have ipfs store chunked copies of added files in the blockstore, pushing to burden of ensuring those files are not changed to the user. The filestore feature is currently still experimental, and must be enabled in your config with:

ipfs config --json Experimental.FilestoreEnabled true

before it can be used. Please see this issue for more details.

Next up, We have merged initial support for ipfs 'Private Networks'. This feature allows users to run ipfs in a mode that will only connect to other peers in the private network. This feature, like the filestore is being released experimentally, but if you're interested please try it out. Instructions for setting it up can be found here.

This release also enables support for the 'mplex' stream muxer by default. This stream multiplexing protocol was available previously via the --enable-mplex-experiment daemon flag, but has now graduated to being 'less experimental' and no longer requires the flag to use it.

Aside from those, we have a good number of bugfixes, perf improvements and new tests. Heres a list of highlights:

0.4.6 - 2017-02-21

Ipfs 0.4.6 contains several bugfixes related to migrations and also contains a few other improvements to other parts of the codebase. Notably:

0.4.0 - 2016-04-05

This is a major release with plenty of new features and bugfixes. It also includes breaking changes which make it incompatible with v0.3.x on the networking layer.

  • Major Changes
    • Multistream
      • The addition of multistream is a breaking change on the networking layer, but gives IPFS implementations the ability to mix and match different stream multiplexers, e.g. yamux, spdystream, or muxado. This adds a ton of flexibility on one of the lower layers of the protocol, and will help us avoid further breaking protocol changes in the future.
    • Files API
      • The new files command and API allow a program to interact with IPFS using familiar filesystem operations, namely: creating directories, reading, writing, and deleting files, listing out different directories, and so on. This feature enables any other application that uses a filesystem-like backend for storage, to use IPFS as its storage driver without having change the application logic at all.
    • Gx
      • go-ipfs now uses gx to manage its dependencies. This means that under the hood, go-ipfs's dependencies are backed by IPFS itself! It also means that go-ipfs is no longer installed using go get. Use make install instead.
  • New Features
    • Web UI
      • Update to new version which is compatible with 0.4.0. (@dignifiedquire)
    • Networking
      • Implement uTP transport. (@whyrusleeping)
      • Allow multiple addresses per configured bootstrap node. (@whyrusleeping)
    • IPNS
      • Improve IPNS resolution performance. (@whyrusleeping)
      • Have dnslink prefer TXT _dnslink.example.com, allows usage of CNAME records. (@Kubuxu)
      • Prevent ipfs name publish when /ipns is mounted. (@noffle)
    • Repo
      • Improve performance of ipfs add. (@whyrusleeping)
      • Add Datastore.NoSync config option for flatfs. (@rht)
      • Implement mark-and-sweep GC. (@whyrusleeping)
      • Allow for GC during ipfs add. (@whyrusleeping)

      • Add support for HTTP OPTIONS requests. (@lidel)
      • Add ipfs diag cmds to view active API requests (@whyrusleeping)
      • Add an IPFS_LOW_MEM environment veriable which relaxes Bitswap's memory usage. (@whyrusleeping)
      • The Docker image now lives at ipfs/go-ipfs and has been completely reworked. (@lgierth)
  • Security fixes
    • The gateway path prefix added in v0.3.10 was vulnerable to cross-site scripting attacks. This release introduces a configurable list of allowed path prefixes. It's called Gateway.PathPrefixes and takes a list of strings, e.g. ["/blog", "/foo/bar"]. The v0.3.x line will not receive any further updates, so please update to v0.4.0 as soon as possible. (@lgierth)
  • Incompatible Changes
    • Install using make install instead of go get (@whyrusleeping)
