go-ipfs OpenBazaar fork

This is the official fork of IPFS used in OpenBazaar. It's comes bundled in the vendor package of openbazaar-go so if you run openbazaar-go you are running this fork.

It is not safe to run the main IPFS codebase in the OpenBazaar network as your node will not be able to communicate with other OpenBazaar nodes.

Diff

This fork is currently based on IPFS v0.4.15 with the following changes:

• namesys/publisher.go change DefaultRecordTTL and DefaultPublishLifetime to one week.

• namesys/namesys.go NewNameSystem takes in a database instance for caching records.

• namesys/namesys.go resolveOnce tries the pubsub resolver again if the DHT fails.

• namesys/pubsub.go NewPubsubResolver takes in a datastore and uses it in place of the memory map.

• namesys/pubsub.go resolveOnce exits with error if not subscribed.

• namesys/pubsub.go resolveOnce remove code block checking EOL validity.

• namesys/routing.go resolveOnce stores the resolved record in the database using the same format as the pubsub resolver.

• namesys/routing.go resolveOnce stores the resolved public key in the database using keyCachePrefix and checks the db when fetching public keys.

• namesys/routing.go resolveOnce is modified to optionally accept an alt-root in the format root:suffix.

• namesys/namesys.go NewNameSystem takes in a custom DNSResolver instance which can be nil.

• namesys/namesys.go resolveOnce splits the key at the : for multihash validation. Passes the full key into the resolver.

• namesys/validator.go validates the record by splitting the key at the : and using everything before.

• repo/config/ipns.go Add QuerySize, BackUpAPI, and UsePersistentCache paramters to IPNS config.

• core/core.go startOnlineServices takes in a DNSResolver to initialize the NameSystem with.

• core/builder.go add a DNSResolver to the build config to pass into startOnlineServices

• core/bootstrap.go add DoneChan to the bootstrap config which is closed when the inital bootstrap finishes. This is in place of blocking for the initial bootstrap.

• core/commands/swarm.go Change the swarm peers output to []string from a private struct. The access control on the struct made the return unusable otherwise.

• core/commands/ipns.go Initialize NewNameSystem with a NewDNSResolver().

• core/commands/dht.go Swap out DHT import with DHT fork.

• core/coreunix/add.go AddWithContext function modified to use CIDv1.

• core/coreunix/add.go NewAddr updated to use prefix and CIDv1.

• core/coreunix/add.go AddR calls fileAddr.PinRoot()

Finally, we've had to patch go-multiaddr to handle CIDv1 in the /ipfs/ addr strings. We'll try to get this merged into the main repo.
