This means setting `StorageMax` on IPFS to 0 -effectively prevents any pins from being explicitly allocated to a peer -(that is, when replication_factor != *everywhere*). - ---- - -### v1.0.0 - 2022-04-22 - -IPFS Cluster v1.0.0 is a major release that represents that this project has -reached maturity and is able to perform and scale on production environment -(50+ million pins and 20 nodes). - -This is a breaking release, v1.0.0 cluster peers are not compatible with -previous cluster peers as we have bumped the RPC protocol version (which had -remained unchanged since 0.12.0). - -This release's major change is the switch to using streaming RPC endpoints for -several RPC methods (listing pins, listing statuses, listing peers, adding -blocks), which we added support for in go-libp2p-gorpc. - -This causes major impact on two areas: - -- Memory consumption with very large pinsets: before, listing all the pins on - the HTTP API required loading all the pins in the pinset into memory, then - responding with a json-array containing the full pinset. When working at - large scale with multimillion pinsets, this caused large memory usage spikes - (whenever the full pinset was needed anywhere). Streaming RPC means - components no longer need to send requests or responses in a single large - collection (a json array), but can individually stream items end-to-end, - without having to load-all and store in memory while the request is being - handled. - -- Adding via cluster peers: before, when adding content to IPFS though a - Cluster peer, it would chunk and send every individual chunk the cluster - peers supposed to store the content, and then they would send it to IPFS - individually, which resulted in a separate `block/put` request against the - IPFS HTTP API. Files with a dozen chunks already showed that performance was - not great. With streaming RPC, we can setup a single libp2p stream from the - adding node to the destinations, and they can stream the blocks with a - single `block/put` multipart-request directly into IPFS. We recommend using - go-ipfs >= 0.12.0 for this. - -These changes affect how cluster peers talk to each other and also how API -endpoints that responded with array collections behave (they now stream json -objects). - -This release additionally includes the first version of the experimental -[IPFS Pinning Service API](https://ipfs.github.io/pinning-services-api-spec/) -for IPFS Cluster. This API runs along the existing HTTP REST API and IPFS -Proxy API and allows sending and querying pins from Cluster using standard -Pinning-service clients (works well with go-ipfs's `ipfs pin remote`). Note -that it does not support authentication nor tracking different requests for -the same CID (request ID is the CID). - -The full list of additional features and bug fixes can be found below. - -#### List of changes - -##### Features - -* restapi/adder: Add `?no-pin=true/false` option to `/add` endpoint | [ipfs-cluster/ipfs-cluster#1590](https://github.com/ipfs-cluster/ipfs-cluster/issues/1590) -* cluster: add `pin_only_on_trusted_peers` config option | [ipfs-cluster/ipfs-cluster#1585](https://github.com/ipfs-cluster/ipfs-cluster/issues/1585) | [ipfs-cluster/ipfs-cluster#1591](https://github.com/ipfs-cluster/ipfs-cluster/issues/1591) -* restapi/client: support querying status for multiple CIDs | [ipfs-cluster/ipfs-cluster#1564](https://github.com/ipfs-cluster/ipfs-cluster/issues/1564) | [ipfs-cluster/ipfs-cluster#1592](https://github.com/ipfs-cluster/ipfs-cluster/issues/1592) -* Pinning Services API | [ipfs-cluster/ipfs-cluster#1213](https://github.com/ipfs-cluster/ipfs-cluster/issues/1213) | [ipfs-cluster/ipfs-cluster#1483](https://github.com/ipfs-cluster/ipfs-cluster/issues/1483) -* restapi/adder: Return pin allocations on add output | [ipfs-cluster/ipfs-cluster#1598](https://github.com/ipfs-cluster/ipfs-cluster/issues/1598) | [ipfs-cluster/ipfs-cluster#1599](https://github.com/ipfs-cluster/ipfs-cluster/issues/1599) -* RPC Streaming | [ipfs-cluster/ipfs-cluster#1602](https://github.com/ipfs-cluster/ipfs-cluster/issues/1602) | [ipfs-cluster/ipfs-cluster#1607](https://github.com/ipfs-cluster/ipfs-cluster/issues/1607) | [ipfs-cluster/ipfs-cluster#1611](https://github.com/ipfs-cluster/ipfs-cluster/issues/1611) | [ipfs-cluster/ipfs-cluster#810](https://github.com/ipfs-cluster/ipfs-cluster/issues/810) | [ipfs-cluster/ipfs-cluster#1437](https://github.com/ipfs-cluster/ipfs-cluster/issues/1437) | [ipfs-cluster/ipfs-cluster#1616](https://github.com/ipfs-cluster/ipfs-cluster/issues/1616) | [ipfs-cluster/ipfs-cluster#1621](https://github.com/ipfs-cluster/ipfs-cluster/issues/1621) | [ipfs-cluster/ipfs-cluster#1631](https://github.com/ipfs-cluster/ipfs-cluster/issues/1631) | [ipfs-cluster/ipfs-cluster#1632](https://github.com/ipfs-cluster/ipfs-cluster/issues/1632) - -##### Bug fixes - -##### Other changes - -* pubsubmon: Remove accrual failure detection | [ipfs-cluster/ipfs-cluster#939](https://github.com/ipfs-cluster/ipfs-cluster/issues/939) | [ipfs-cluster/ipfs-cluster#1586](https://github.com/ipfs-cluster/ipfs-cluster/issues/1586) | [ipfs-cluster/ipfs-cluster#1589](https://github.com/ipfs-cluster/ipfs-cluster/issues/1589) -* crdt: log with INFO when batches are committed | [ipfs-cluster/ipfs-cluster#1596](https://github.com/ipfs-cluster/ipfs-cluster/issues/1596) -* Dependency upgrades | [ipfs-cluster/ipfs-cluster#1613](https://github.com/ipfs-cluster/ipfs-cluster/issues/1613) | [ipfs-cluster/ipfs-cluster#1617](https://github.com/ipfs-cluster/ipfs-cluster/issues/1617) | [ipfs-cluster/ipfs-cluster#1627](https://github.com/ipfs-cluster/ipfs-cluster/issues/1627) -* Bump RPC protocol version | [ipfs-cluster/ipfs-cluster#1615](https://github.com/ipfs-cluster/ipfs-cluster/issues/1615) -* Replace cid.Cid with api.Cid wrapper type | [ipfs-cluster/ipfs-cluster#1626](https://github.com/ipfs-cluster/ipfs-cluster/issues/1626) -* Provide string JSON marshaling for PinType | [ipfs-cluster/ipfs-cluster#1628](https://github.com/ipfs-cluster/ipfs-cluster/issues/1628) -* ipfs-cluster-ctl should exit with status 1 when an argument error happens | [ipfs-cluster/ipfs-cluster#1633](https://github.com/ipfs-cluster/ipfs-cluster/issues/1633) | [ipfs-cluster/ipfs-cluster#1634](https://github.com/ipfs-cluster/ipfs-cluster/issues/1634) -* Revamp and fix basic exported metrics: pins, queued, pinning, pin errors | [ipfs-cluster/ipfs-cluster#1187](https://github.com/ipfs-cluster/ipfs-cluster/issues/1187) | [ipfs-cluster/ipfs-cluster#1470](https://github.com/ipfs-cluster/ipfs-cluster/issues/1470) | [ipfs-cluster/ipfs-cluster#1637](https://github.com/ipfs-cluster/ipfs-cluster/issues/1637) - -#### Upgrading notices - -As mentioned, all peers in the cluster should upgrade and things will heavily break otherwise. - -##### Configuration changes - -There are no breaking configuration changes. Other than that: - -* A `pin_only_on_trusted_peers` boolean option that defaults to `false` has - been added to the `cluster` configuration section. When enabled, only - trusted peers will be considered when allocating pins. -* A new `pinsvcapi` section is now added to the `api` configuration section - for newly-initialized configurations. When this section is present, the - experimental Pinning Services API is launched. See the docs for the - different options. Most of the code/options are similar to the `restapi` - section as both share most of the code. - -##### REST API - -###### Streaming responses - -The following endpoint responses have changed: - -* `/allocations` returned a json array of api.Pin object and now it will stream them. -* `/pins` returned a json array of api.PinInfo objects and now it will stream them. -* `/recover` returned a json array of api.PinInfo objects and now it will stream them. - -Failures on streaming endpoints are captured in request Trailer headers (same -as `/add`), in particular with a `X-Stream-Error` trailer. Note that the -`X-Stream-Error` trailer may appear even no error happened (empty value in -this case). - -###### JSON-encoding of CIDs - -As of v1.0.0, every "cid" as returned inside any REST API object will no -longer encode as: - -``` -{ "/" : "" } -``` - -but instead just as `"cid"`. - -###### Add endpoint changes - -There are two small backwards compatible changes to the `/add` endpoint: - -* A `?no-pin` query option has been added. In this case, cluster will not pin -the content after having added it. -* The output objects returned when adding (i.e. the ones containing the CIDs - of the files) now include an `Allocations` field, with an array of peer IDs - corresponding to the peers on which the blocks were added. - -###### Pin object changes - -`Pin` objects (returned from `/allocations`, `POST /pins` etc). will not -encode the Type as a human-readable string and not as a number, as previously -happened. - -###### PinInfo object changes - -`PinInfo`/`GlobalPinInfo` objects (returned from `/pins` and `/recover` endpoitns), now -include additional fields (which before were only accessible via `/allocations`): - -- `allocations`: an array of peer IDs indicating the pin allocations. -- `origins`: the list of origins associated to this pin. -- `metadata`: an object with pin metadata. -- `created`: date when the pin was added to the cluster. -- `ipfs_peer_id`: IPFS peer ID to which the object is pinned (when known). -- `ipfs_peer_addresses`: IPFS addresses of the IPFS daemon to which the object is pinned (when known). - -##### Pinning Services API - -This API now exists. It does not support Authentication and is experimental. - -##### IPFS Proxy API - -The `/add?pin=false` call will no longer trigger a cluster pin followed by an unpin. - -The `/pin/ls?stream=true` query option is now supported. - -##### Go APIs - -There have been many changes to different interfaces (i.e. to stream out -collections over channels rather than return slices). - -We have also taken the opportunity to get rid of pointers to objects in many -places. This was a bad step, which makes cluster perform many more allocations -that it should, and as a result causes more GC pressure. In any case, it was -not a good Go development practice to use referenced types all around for -objects that are not supposed to be mutated. - -##### Other - -The following metrics are now available in the Prometheus endpoint when enabled: - -``` -ipfscluster_pins -ipfscluster_pins_pin_queued -ipfscluster_pins_pin_error -ipfscluster_pins_pinning -``` - - ---- - -### v0.14.5 - 2022-02-16 - -This is a minor IPFS Cluster release. The main feature is the upgrade of the -go-ds-crdt library which now supports resuming the processing of CRDT-DAGs -that were not fully synced. - -On first start on an updated node, the CRDT library will have to re-walk the -full CRDT-DAG. This happens in the background. - -For the full list of feature and bugfixes, see list below. - -#### List of changes - -##### Features - -* CRDT: update with RepairInterval option and more workers | [ipfs-cluster/ipfs-cluster#1561](https://github.com/ipfs-cluster/ipfs-cluster/issues/1561) | [ipfs-cluster/ipfs-cluster#1576](https://github.com/ipfs-cluster/ipfs-cluster/issues/1576) -* Add `?cids` query parameter to /pins: limit status request to several CIDs | [ipfs-cluster/ipfs-cluster#1562](https://github.com/ipfs-cluster/ipfs-cluster/issues/1562) -* Pintracker improvements | [ipfs-cluster/ipfs-cluster#1556](https://github.com/ipfs-cluster/ipfs-cluster/issues/1556) | [ipfs-cluster/ipfs-cluster#1554](https://github.com/ipfs-cluster/ipfs-cluster/issues/1554) | [ipfs-cluster/ipfs-cluster#1212](https://github.com/ipfs-cluster/ipfs-cluster/issues/1212) - * Status information shows peer ID of IPFS peer pinning the content - * Peernames correctly set for remote peers on status objects - * Pin names not set for in-flight pin status objects - -##### Bug fixes - -* Fix: logging was too noisy | [ipfs-cluster/ipfs-cluster#1581](https://github.com/ipfs-cluster/ipfs-cluster/issues/1581) | [ipfs-cluster/ipfs-cluster#1579](https://github.com/ipfs-cluster/ipfs-cluster/issues/1579) -* Remove warning message about informer metrics | [ipfs-cluster/ipfs-cluster#1543](https://github.com/ipfs-cluster/ipfs-cluster/issues/1543) -* Fix: IPFS repo/stat gets hammered on busy peers | [ipfs-cluster/ipfs-cluster#1559](https://github.com/ipfs-cluster/ipfs-cluster/issues/1559) -* Fix: faster shutdown by aborting state list on context cancellation | [ipfs-cluster/ipfs-cluster#1555](https://github.com/ipfs-cluster/ipfs-cluster/issues/1555) - -##### Other changes - -* Leave peername empty when unknown on status response | [ipfs-cluster/ipfs-cluster#1569](https://github.com/ipfs-cluster/ipfs-cluster/issues/1569) | [ipfs-cluster/ipfs-cluster#1575](https://github.com/ipfs-cluster/ipfs-cluster/issues/1575) -* Fix comment in graphs.go | [ipfs-cluster/ipfs-cluster#1570](https://github.com/ipfs-cluster/ipfs-cluster/issues/1570) | [ipfs-cluster/ipfs-cluster#1574](https://github.com/ipfs-cluster/ipfs-cluster/issues/1574) -* Make `/add?local=true` requests forcefully allocate to local peer | [ipfs-cluster/ipfs-cluster#1560](https://github.com/ipfs-cluster/ipfs-cluster/issues/1560) -* Dependency upgrades | [ipfs-cluster/ipfs-cluster#1580](https://github.com/ipfs-cluster/ipfs-cluster/issues/1580) - -#### Upgrading notices - -##### Configuration changes - -Configuration is backwards compatible with previous versions. - -The `consensus/crdt` section has a new option `repair_interval` which is set -by default to `1h` and controls how often we check if the crdt DAG needs to be -reprocessed (i.e. when it becomes marked dirty due to an error). Setting it to -`0` disables repairs. - -The `ipfs_connector/ipfshttp` section has a new option -`informer_trigger_interval` which defaults to `0` (disabled). This controls -whether clusters issue a metrics update every certain number of pins (i.e. for -fine-grain control of freespace after a pin happens). - -The `monitor/pubsubmon/failure_threshold` option no longer has any effect. - -##### REST API - -The `/pins` (StatusAll) endpoint now takes a `?cid=cid1,cid2` option which -allows to filter the resulting list to specific CIDs. - -##### Go APIs - -We added a `LatestForPeer()` method to the PeerMonitor interface which returns -the latest metric of a certain type received by a peer. - -##### Other - -Before, adding content using the `local=true` option would add the blocks to -the peer receiving the request and then allocate the pin normally (i.e. to the -peers with most free space available, which may or not be the local peer). Now, -"local add" requests will always allocate the pin to the local peer since it -already has the content. - -Before, we would send a freespace metric update every 10 pins. After: we don't -do it anymore and relay on the normal metric interval, unless -`informer_trigger_interval` is configured. - -The CRDT library will create a database of processed DAG blocks during the -first start on an upgraded node. This happens on the background and should -only happen once. Peers with very large CRDT-DAGs, may experience increased -disk usage during this time. - ---- - - -### v0.14.4 - 2022-01-11 - -This is a minor IPFS Cluster release with additional performance improvements. - -On one side, we have improved branch pruning when syncing CRDT dags. This -should improve the time it takes for a peer to sync the pinset when joining a -high-activity cluster, where branching happens often. - -On the other side, we have improved how Cluster finds and re-triggers pinning -operations for items that failed to pin previously, heavily reducing the -pressure on the IPFS daemon and speeding up the operation. - - -#### List of changes - -##### Features - -No new features. - -##### Bug fixes - -* Improved pruning on crdt-sync | [ipfs-cluster/ipfs-cluster#1541](https://github.com/ipfs-cluster/ipfs-cluster/issues/1541) -* Pintracker: avoid pin/ls for every item | [ipfs-cluster/ipfs-cluster#1538](https://github.com/ipfs-cluster/ipfs-cluster/issues/1538) -* Pintracker: set unexpectedly_unpinned status correctly | [ipfs-cluster/ipfs-cluster#1537](https://github.com/ipfs-cluster/ipfs-cluster/issues/1537) -* Tags informer: TTL should be default when not provided | [ipfs-cluster/ipfs-cluster#1519](https://github.com/ipfs-cluster/ipfs-cluster/issues/1519) - -##### Other changes - -* ipfs-cluster-service: buffered i/o on state import/export | [ipfs-cluster/ipfs-cluster#1517](https://github.com/ipfs-cluster/ipfs-cluster/issues/1517) -* Dependency upgrades, go-libp2p v0.17.0 | 1540 - -#### Upgrading notices - -##### Configuration changes - -No changes. - -##### REST API - -The `/pins/recover` (RecoverAll) endpoint now only returns items that have -been re-queued for pinning (because they were in error). Before, it returned -all items in the state (similar to the `/pins` endpoint, but at a huge perf -impact with large pinsets). - -##### Go APIs - -No changes. - -##### Other - -`ipfs-cluster-ctl recover` only returns items that have been re-queued (see -REST APIs above). - ---- - -### v0.14.3 - 2022-01-03 - -This is a minor IPFS Cluster release with some performance improvements and -bug fixes. - -First, we have improved the speed at which the pinset can be listed (around -3x). This is important for very large clusters with millions of items on the -pinset. Cluster peers regularly check on all items in the pinset (i.e. to -re-pin failed items or remove expired pins), so this means these operations -will consume less resources and complete faster. - -Second, we have added additional options to the `state import` command to -provide more flexibility when migrating content to a new cluster. For example, -allocations and replication factors for all pins can be replaced on -import. One usecase is to convert a cluster with "replicate-everywhere" pins -into one cluster with pins allocated to a particular set of peers (as a prior -step to scaling up the cluster by adding more peers). - -Among the bugs fixed, the worst was one causing errors when deserializing some -pins from their JSON representation. This happened when pins had the `Origins` -property set. - - -#### List of changes - -##### Features - -* State import: allow replication factor and allocations overwrite | [ipfs-cluster/ipfs-cluster#1508](https://github.com/ipfs-cluster/ipfs-cluster/issues/1508) - -##### Bug fixes - -* Fix state deserialization | [ipfs-cluster/ipfs-cluster#1507](https://github.com/ipfs-cluster/ipfs-cluster/issues/1507) -* Fix pintracker shutdown errors | [ipfs-cluster/ipfs-cluster#1510](https://github.com/ipfs-cluster/ipfs-cluster/issues/1510) -* API: CORS pre-flight (OPTIONS) requests should bypass authentication | [ipfs-cluster/ipfs-cluster#1512](https://github.com/ipfs-cluster/ipfs-cluster/issues/1512) | [ipfs-cluster/ipfs-cluster#1513](https://github.com/ipfs-cluster/ipfs-cluster/issues/1513) | [ipfs-cluster/ipfs-cluster#1514](https://github.com/ipfs-cluster/ipfs-cluster/issues/1514) -* Monitor: avoid sending invalid metrics | [ipfs-cluster/ipfs-cluster#1511](https://github.com/ipfs-cluster/ipfs-cluster/issues/1511) - -##### Other changes - -* Performance improvements to state list and logging for large states | [ipfs-cluster/ipfs-cluster#1510](https://github.com/ipfs-cluster/ipfs-cluster/issues/1510) - -#### Upgrading notices - -##### Configuration changes - -No changes. - -##### REST API - -No changes. - -##### Go APIs - -No changes. - -##### Other - -`ipfs-cluster-service state import` has new `rmin`, `rmax` and `allocations` -flags. See `ipfs-cluster-service state import --help` for more information. - ---- - -### v0.14.2 - 2021-12-09 - -This is a minor IPFS Cluster release focused on providing features for -production Cluster deployments with very high pin ingestion rates. - -It addresses two important questions from our users: - - * How to ensure that my pins are automatically pinned on my cluster peers - around the world in a balanced fashion. - * How to ensure that items that cannot be pinned do not delay the pinning - of items that are available. - -We address the first of the questions by introducing an improved allocator and -user-defined "tag" metrics. Each cluster peer can now be tagged, and the -allocator can be configured to pin items in a way that they are distributed -among tags. For example, a cluster peer can tagged with `region: us, -availability-zone: us-west` and so on. Assuming a cluster made of 6 peers, 2 -per region, and one per availability zone, the allocator would ensure that a -pin with replication factor = 3 lands in the 3 different regions and in the -availability zones with most available space of the two. - -The second question is addressed by enriching pin metadata. Pins will now -store the time that they were added to the cluster. The pin tracker will -additionally keep track of how many times an operation has been retried. Using -these two items, we can prioritize pinning of items that are new and have not -repeatedly failed to pin. The max age and max number of retries used to -prioritize a pin can be controlled in the configuration. - -Please see the information below for more details about how to make use and -configure these new features. - -#### List of changes - -##### Features - - * Tags informer and partition-based allocations | [ipfs-cluster/ipfs-cluster#159](https://github.com/ipfs-cluster/ipfs-cluster/issues/159) | [ipfs-cluster/ipfs-cluster#1468](https://github.com/ipfs-cluster/ipfs-cluster/issues/1468) | [ipfs-cluster/ipfs-cluster#1485](https://github.com/ipfs-cluster/ipfs-cluster/issues/1485) - * Add timestamps to pin objects | [ipfs-cluster/ipfs-cluster#1484](https://github.com/ipfs-cluster/ipfs-cluster/issues/1484) | [ipfs-cluster/ipfs-cluster#989](https://github.com/ipfs-cluster/ipfs-cluster/issues/989) - * Support priority pinning for recent pins with small number of retries | [ipfs-cluster/ipfs-cluster#1469](https://github.com/ipfs-cluster/ipfs-cluster/issues/1469) | [ipfs-cluster/ipfs-cluster#1490](https://github.com/ipfs-cluster/ipfs-cluster/issues/1490) - -##### Bug fixes - - * Fix flaky adder test | [ipfs-cluster/ipfs-cluster#1461](https://github.com/ipfs-cluster/ipfs-cluster/issues/1461) | [ipfs-cluster/ipfs-cluster#1462](https://github.com/ipfs-cluster/ipfs-cluster/issues/1462) - -##### Other changes - - * Refactor API to facilitate re-use of functionality | [ipfs-cluster/ipfs-cluster#1471](https://github.com/ipfs-cluster/ipfs-cluster/issues/1471) - * Move testing to Github Actions | [ipfs-cluster/ipfs-cluster#1486](https://github.com/ipfs-cluster/ipfs-cluster/issues/1486) - * Dependency upgrades (go-libp2p v0.16.0 etc.) | [ipfs-cluster/ipfs-cluster#1491](https://github.com/ipfs-cluster/ipfs-cluster/issues/1491) | [ipfs-cluster/ipfs-cluster#1501](https://github.com/ipfs-cluster/ipfs-cluster/issues/1501) | [ipfs-cluster/ipfs-cluster#1504](https://github.com/ipfs-cluster/ipfs-cluster/issues/1504) - * Improve `health metrics ` output in ipfs-cluster-ctl | [ipfs-cluster/ipfs-cluster#1506](https://github.com/ipfs-cluster/ipfs-cluster/issues/1506) - -#### Upgrading notices - -Despite of the new features, cluster peers should behave exactly as before -when using the previous configuration and should interact well with peers in -the previous version. However, for the new features to take full effect, all -peers should be upgraded to this release. - -##### Configuration changes - -The `pintracker/stateless` configuration sector gets 2 new options, which will take defaults when unset: - - * `priority_pin_max_age`, with a default of `24h`, and - * `priority_pin_max_retries`, with a default of `5`. - -A new informer type called "tags" now exists. By default, in has a subsection -in the `informer` configuration section with the following defaults: - -```json - "informer": { - "disk": {...} - }, - "tags": { - "metric_ttl": "30s", - "tags": { - "group": "default" - } - } - }, -``` - -This enables the use of the "tags" informer. The `tags` configuration key in -it allows to add user-defined tags to this peer. For every tag, a new metric -will be broadcasted to other peers in the cluster carrying the tag -information. By default, peers would broadcast a metric of type "tag:group" -and value "default" (`ipfs-cluster-ctl health metrics` can be used to see what -metrics a cluster peer knows about). These tags metrics can be used to setup -advanced allocation strategies using the new "balanced" allocator described -below. - -A new `allocator` top level section with a `balanced` configuration -sub-section can now be used to setup the new allocator. It has the following -default on new configurations: - -```json - "allocator": { - "balanced": { - "allocate_by": [ - "tag:group", - "freespace" - ] - } - }, -``` - -When the allocator is NOT defined (legacy configurations), the `allocate_by` -option is only set to `["freespace"]`, to keep backwards compatibility (the -tags allocator with a "group:default" tag will not be present). - -This asks the allocator to allocate pins first by the value of the "group" -tag-metric, as produced by the tag informer, and then by the value of the -"freespace" metric. Allocating solely by the "freespace" is the equivalent of -the cluster behavior on previous versions. This default assumes the default -`informer/tags` configuration section mentioned above is present. - -##### REST API - -The objects returned by the `/pins` endpoints ("GlobalPinInfo" types) now -include an additional `attempt_count` property, that counts how many times the -pin or unpin operation was retried, and a `priority_pin` boolean property, -that indicates whether the ongoing pin operation was last queued in the -priority queue or not. - -The objects returned by the `/allocations` enpdpoints ("Pin" types) now -include an additional `timestamp` property. - -The objects returned by the `/monitor/metrics/` endpoint now include a -`weight` property, which is used to sort metrics (before they were sorted by -parsing the value as decimal number). - -The REST API client will now support QUIC for libp2p requests whenever not -using private networks. - -##### Go APIs - -There are no relevant changes other than the additional fields in the objects -as mentioned by the section right above. - -##### Other - -Nothing. - ---- - - -### v0.14.1 - 2021-08-16 - -This is an IPFS Cluster maintenance release addressing some issues and -bringing a couple of tweaks. The main fix is an issue that would prevent -cluster peers with very large pinsets (in the millions of objects) from fully -starting quickly. - -This release is fully compatible with the previous release. - -#### List of changes - -##### Features - -* Improve support for pre-0.14.0 peers | [ipfs-cluster/ipfs-cluster#1409](https://github.com/ipfs-cluster/ipfs-cluster/issues/1409) | [ipfs-cluster/ipfs-cluster#1446](https://github.com/ipfs-cluster/ipfs-cluster/issues/1446) -* Improve log-level handling | [ipfs-cluster/ipfs-cluster#1439](https://github.com/ipfs-cluster/ipfs-cluster/issues/1439) -* ctl: --wait returns as soon as replication-factor-min is reached | [ipfs-cluster/ipfs-cluster#1427](https://github.com/ipfs-cluster/ipfs-cluster/issues/1427) | [ipfs-cluster/ipfs-cluster#1444](https://github.com/ipfs-cluster/ipfs-cluster/issues/1444) - -##### Bug fixes - -* Fix some data races in tests | [ipfs-cluster/ipfs-cluster#1428](https://github.com/ipfs-cluster/ipfs-cluster/issues/1428) -* Do not block peer startup while waiting for RecoverAll | [ipfs-cluster/ipfs-cluster#1436](https://github.com/ipfs-cluster/ipfs-cluster/issues/1436) | [ipfs-cluster/ipfs-cluster#1438](https://github.com/ipfs-cluster/ipfs-cluster/issues/1438) -* Use HTTP 307-redirects on restapi paths ending with "/" | [ipfs-cluster/ipfs-cluster#1415](https://github.com/ipfs-cluster/ipfs-cluster/issues/1415) | [ipfs-cluster/ipfs-cluster#1445](https://github.com/ipfs-cluster/ipfs-cluster/issues/1445) - -##### Other changes - -* Dependency upgrades | [ipfs-cluster/ipfs-cluster#1451](https://github.com/ipfs-cluster/ipfs-cluster/issues/1451) - -#### Upgrading notices - -##### Configuration changes - -No changes. Configurations are fully backwards compatible. - -##### REST API - -Paths ending with a `/` (slash) were being automatically redirected to the -path without the slash using a 301 code (permanent redirect). However, most -clients do not respect the method name when following 301-redirects, thus a -POST request to `/allocations/` would become a GET request to `/allocations`. - -We have now set these redirects to use 307 instead (temporary -redirect). Clients do keep the HTTP method when following 307 redirects. - -##### Go APIs - -The parameters object to the RestAPI client `WaitFor` function now has a -`Limit` field. This allows to return as soon as a number of peers have reached -the target status. When unset, previous behavior should be maintained. - -##### Other - -Per the `WaitFor` modification above, `ipfs-cluster-ctl` now sets the limit to -the replication-factor-min value on pin/add commands when using the `--wait` -flag. These will potentially return earlier. - ---- - -### v0.14.0 - 2021-07-09 - -This IPFS Cluster release brings a few features to improve cluster operations -at scale (pinsets over 100k items), along with some bug fixes. - -This release is not fully compatible with previous ones. Nodes on different -versions will be unable to parse metrics from each other (thus `peers ls` -will not report peers on different versions) and the StatusAll RPC method -(a.k.a `ipfs-cluster-ctl status` or `/pins` API endpoint) will not work. Hence -the minor version bump. **Please upgrade all of your cluster peers**. - -This release brings a few key improvements to the cluster state storage: -badger will automatically perform garbage collection on regular intervals, -resolving a long standing issue of badger using up to 100x the actual needed -space. Badger GC will automatically be enabled with defaults, which will -result in increased disk I/O if there is a lot to GC 15 minutes after starting -the peer. **Make sure to disable GC manually if increased disk I/O during GC -may affect your service upon upgrade**. In our tests the impact was soft -enough to consider this a safe default, though in environments with very -constrained disk I/O it will be surely noticed, at least in the first GC -cycle, since the datastore was never GC'ed before. - -Badger is the datastore we are more familiar with and the most scalable choice -(chosen by both IPFS and Filecoin). However, it may be that badger behavior -and GC-needs are not best suited or not preferred, or more downsides are -discovered in the future. For those cases, we have added the option to run -with a leveldb backend as an alternative. Level DB does not need GC and it -will auto-compact. It should also scale pretty well for most cases, though we -have not tested or compared against badger with very large pinsets. The -backend can be configured during the daemon `init`, along with the consensus -component using a new `--datastore` flag. Like the default Badger backend, the -new LevelDB backend exposes all LevelDB internal configuration options. - -Additionally, operators handling very large clusters may have noticed that -checking status of pinning,queued items (`ipfs-cluster-ctl status --filter -pinning,queued`) took very long as it listed and iterated on the full ipfs -pinset. We have added some fixes so that we save the time when filtering for -items that do not require listing the full state. - -Finally, cluster pins now have an `origins` option, which allows submitters to -provide hints for providers of the content. Cluster will instruct IPFS to -connect to the `origins` of a pin before pinning. Note that for the moment -[ipfs will keep connected to those peers permanently](https://github.com/ipfs-cluster/ipfs-cluster/issues/1376). - -Please read carefully through the notes below, as the release includes subtle -changes in configuration, defaults and behaviors which may in some cases -affect you (although probably will not). - -#### List of changes - -##### Features - -* Set disable_repinning to true by default, for new configurations | [ipfs-cluster/ipfs-cluster#1398](https://github.com/ipfs-cluster/ipfs-cluster/issues/1398) -* Efficient status queries with filters | [ipfs-cluster/ipfs-cluster#1360](https://github.com/ipfs-cluster/ipfs-cluster/issues/1360) | [ipfs-cluster/ipfs-cluster#1377](https://github.com/ipfs-cluster/ipfs-cluster/issues/1377) | [ipfs-cluster/ipfs-cluster#1399](https://github.com/ipfs-cluster/ipfs-cluster/issues/1399) -* User-provided pin "origins" | [ipfs-cluster/ipfs-cluster#1374](https://github.com/ipfs-cluster/ipfs-cluster/issues/1374) | [ipfs-cluster/ipfs-cluster#1375](https://github.com/ipfs-cluster/ipfs-cluster/issues/1375) -* Provide darwin/arm64 binaries (Apple M1).

A GC cycle is made by -multiple GC rounds. Setting `gc_sleep` to `"0s"` will result in a single GC -round. - -Finally, nodes initializing with `--datastore leveldb` will obtain a -`datastore.leveldb` section (instead of a `badger` one). Configurations can -only include one datastore section, either `badger` or `leveldb`. Currently we -offer no way to convert states between the two datastore backends. - -##### REST API - -Pin options (`POST /add` and `POST /pins` endpoints) now take an `origins` -query parameter as an additional pin option. It can be set to a -comma-separated list of full peer multiaddresses to which IPFS can connect to -fetch the content. Only the first 10 multiaddresses will be taken into -account. - -The response of `POST /add?format=car` endpoint when adding a CAR file (a single -pin progress object) always had the "size" field set to 0. This is now set to -the unixfs FileSize property, when the root of added CAR correspond to a -unixfs node of type File. In any other case, it stays at 0. - -The `GET /pins` endpoint reports pin status for all pins in the pinset by -default and optionally takes a `filter` query param. Before, it would include -a full GlobalPinInfo object for a pin as long as the status of the CID in one -of the peers matched the filter, so the object could include statuses for -other cluster peers for that CID which did not match the filter. Starting on -this version, the returned statuses will be fully limited to those of the -peers matching the filter. - -On the same endpoint, a new `unexpectedly_unpinned` pin status has been -added, which can also be used as a filter. Previously, pins in this state were -reported as `pin_error`. Note the `error` filter does not match -`unexpectedly_unpinned` status as it did before, which should be queried -directly (or without any filter). - -##### Go APIs - -The PinTracker interface has been updated so that the `StatusAll` method takes -a TrackerStatus filter. The stateless pintracker implementation has been -updated accordingly. - -##### Other - -Docker containers now support `IPFS_CLUSTER_DATASTORE` to set the datastore -type during initialization (similar to `IPFS_CLUSTER_CONSENSUS`). - -Due to the deprecation of the multicodecs repository, we no longer serialize -metrics by prepending the msgpack multicodec code to the bytes and instead -encode the metrics directly. This means older peers will not know how to -deserialize metrics from newer peers, and vice-versa. While peers will keep -working (particularly follower peers will keep tracking content etc), peers -will not include other peers with different versions in their "peerset and -many operations that rely on this will not work as intended or show partial -views. - ---- - -### v0.13.3 - 2021-05-14 - -IPFS Cluster v0.13.3 brings two new features: CAR file imports and crdt-commit batching. - -The first one allows to upload CAR files directly to the Cluster using the -existing Add endpoint with a new option set: `/add?format=car`. The endpoint -remains fully backwards compatible. CAR files are a simple wrapper around a -collection of IPFS blocks making up a DAG. Thus, this enables arbitrary DAG -imports directly through the Cluster REST API, taking advantange of the rest -of its features like basic-auth access control, libp2p endpoint and multipeer -block-put when adding. - -The second feature unlocks large escalability improvements for pin ingestion -with the crdt "consensus" component. By default, each pin or unpin requests -results in an insertion to the crdt-datastore-DAG that maintains and syncs the -state between nodes, creating a new root. Batching allows to group multiple -updates in a single crdt DAG-node. This reduces the number of broadcasts, the -depth of the DAG, the breadth of the DAG and the syncing times when the -Cluster is ingesting many pins, removing most of the overhead in the -process. The batches are automatically committed when reaching a certain age or -a certain size, both configurable. - -Additionally, improvements to timeout behaviors have been introduced. - -For more details, check the list below and the latest documentation on the -[website](https://ipfscluster.io). - -#### List of changes - -##### Features - -* Support adding CAR files | [ipfs-cluster/ipfs-cluster#1343](https://github.com/ipfs-cluster/ipfs-cluster/issues/1343) -* CRDT batching support | [ipfs-cluster/ipfs-cluster#1008](https://github.com/ipfs-cluster/ipfs-cluster/issues/1008) | [ipfs-cluster/ipfs-cluster#1346](https://github.com/ipfs-cluster/ipfs-cluster/issues/1346) | [ipfs-cluster/ipfs-cluster#1356](https://github.com/ipfs-cluster/ipfs-cluster/issues/1356) - -##### Bug fixes - -* Improve timeouts and timeout faster when dialing | [ipfs-cluster/ipfs-cluster#1350](https://github.com/ipfs-cluster/ipfs-cluster/issues/1350) | [ipfs-cluster/ipfs-cluster#1351](https://github.com/ipfs-cluster/ipfs-cluster/issues/1351) - -##### Other changes - -* Dependency upgrades | [ipfs-cluster/ipfs-cluster#1357](https://github.com/ipfs-cluster/ipfs-cluster/issues/1357) - -#### Upgrading notices - -##### Configuration changes - -The `crdt` section of the configuration now has a `batching` subsection which controls batching settings: - -```json -"batching": { - "max_batch_size": 0, - "max_batch_age": "0s" -} -``` - -An additional, hidden `max_queue_size` option exists, with default to -`50000`. The meanings of the options are documented on the reference (website) -and the code. - -Batching is disabled by default. To be enabled, both `max_batch_size` and -`max_batch_age` need to be set to positive values. - -The `cluster` section of the configuration has a new `dial_peer_timeout` -option, which defaults to "3s". It controls the default dial timeout when -libp2p is attempting to open a connection to a peer. - -##### REST API - -The `/add` endpoint now understands a new query parameter `?format=`, which -can be set to `unixfs` (default), or `car` (when uploading a CAR file). CAR -files should have a single root. Additional parts in multipart uploads for CAR -files are ignored. - -##### Go APIs - -The `AddParams` object that controls API options for the Add endpoint has been -updated with the new `Format` option. - -##### Other - -Nothing. - - - ---- - -### v0.13.2 - 2021-04-06 - -IPFS Cluster v0.13.2 is a maintenance release addressing bugs and adding a -couple of small features.

RPC endpoints affected are only used locally. - -##### Other - -Nothing. - ---- - -### v0.13.0 - 2020-05-19 - -IPFS Cluster v0.13.0 provides many improvements and bugfixes on multiple fronts. - -First, this release takes advantange of all the major features that have -landed in libp2p and IPFS lands (via ipfs-lite) during the last few months, -including the dual-DHT and faster block exchange with Bitswap. On the -downside, **QUIC support for private networks has been temporally dropped**, -which means we cannot use the transport for Cluster peers anymore. We have disabled -QUIC for the time being until private network support is re-added. - -Secondly, `go-ds-crdt` has received major improvements since the last version, -resolving some bugs and increasing performance. Because of this, **cluster -peers in CRDT mode running older versions will be unable to process updates -sent by peers running the newer versions**. This means, for example, that -followers on v0.12.1 and earlier will be unable to receive updates from -trusted peers on v0.13.0 and later. However, peers running v0.13.0 will still -understand updates sent from older peers. - -Finally, we have resolved some bugs and added a few very useful features, -which are detailed in the list below. We recommend everyone to upgrade as soon -as possible for a swifter experience with IPFS Cluster. - -#### List of changes - -##### Features - -* Support multiple listen interfaces | [ipfs-cluster/ipfs-cluster#1000](https://github.com/ipfs-cluster/ipfs-cluster/issues/1000) | [ipfs-cluster/ipfs-cluster#1010](https://github.com/ipfs-cluster/ipfs-cluster/issues/1010) | [ipfs-cluster/ipfs-cluster#1002](https://github.com/ipfs-cluster/ipfs-cluster/issues/1002) -* Show expiration information in `ipfs-cluster-ctl pin ls` | [ipfs-cluster/ipfs-cluster#998](https://github.com/ipfs-cluster/ipfs-cluster/issues/998) | [ipfs-cluster/ipfs-cluster#1024](https://github.com/ipfs-cluster/ipfs-cluster/issues/1024) | [ipfs-cluster/ipfs-cluster#1066](https://github.com/ipfs-cluster/ipfs-cluster/issues/1066) -* Show pin names in `ipfs-cluster-ctl status` (and API endpoint) | [ipfs-cluster/ipfs-cluster#1129](https://github.com/ipfs-cluster/ipfs-cluster/issues/1129) -* Allow updating expiration when doing `pin update` | [ipfs-cluster/ipfs-cluster#996](https://github.com/ipfs-cluster/ipfs-cluster/issues/996) | [ipfs-cluster/ipfs-cluster#1065](https://github.com/ipfs-cluster/ipfs-cluster/issues/1065) | [ipfs-cluster/ipfs-cluster#1013](https://github.com/ipfs-cluster/ipfs-cluster/issues/1013) -* Add "direct" pin mode.

The RPC endpoint has -changed accordingly, but since this is a private endpoint, it does not affect -interoperability between peers. - -The `api.GlobalPinInfo` type now maps every peer to a new `api.PinInfoShort` -type, that does not include any redundant information (Cid, Peer), as the -`PinInfo` type did. The `Cid` is available as a top-level field. The `Peer` -corresponds to the map key. A new `Name` top-level field contains the Pin -Name. - -The `api.PinInfo` file includes also a new `Name` field. - -##### Other - -From this release, IPFS Cluster peers running in different minor versions will -remain compatible at the RPC layer (before, all cluster peers had to be -running on precisely the same minor version to be able to communicate). This -means that v0.13.0 peers are still compatible with v0.12.x peers (with the -caveat for CRDT-peers mentioned at the top). `ipfs-cluster-ctl --enc=json id` -shows information about the RPC protocol used. - -Since the QUIC libp2p transport does not support private networks at this -point, it has been disabled, even though we keep the QUIC endpoint among the -default listeners. - ---- - -### v0.12.1 - 2019-12-24 -

These are treated as libp2p bootstrap addreses (do not mix with Raft bootstrap process). This setting is mostly useful for CRDT collaborative clusters, as template configurations can be distributed including bootstrap peers (usually the same as trusted peers). The values are the full multiaddress of these peers: `/ip4/x.x.x.x/tcp/1234/p2p/Qmxxx...`. - * `listen_multiaddress` can now be set to be an array providing multiple listen multiaddresses, the new defaults being `/tcp/9096` and `/udp/9096/quic`. - * `enable_relay_hop` (true by default), lets the cluster peer act as a relay for other cluster peers behind NATs. This is only for the Cluster network. As a reminder, while this setting is problematic on IPFS (due to the amount of traffic the HOP peers start relaying), the cluster-peers networks are smaller and do not move huge amounts of content around. - * The `ipfs_sync_interval` option disappears as the stateless tracker does not keep a state that can lose synchronization with IPFS. -* `ipfshttp` section: - * A new `repogc_timeout` key specifies the timeout for garbage collection operations on IPFS. It is set to 24h by default. - - -##### REST API - -The `pin/add` and `add` endpoints support two new query parameters to indicate pin expirations: `expire-at` (with an expected value in RFC3339 format) and `expire-in` (with an expected value in Go's time format, i.e. `12h`). `expire-at` has preference. - -A new `/ipfs/gc` endpoint has been added to trigger GC in the IPFS daemons attached to Cluster peers. It supports the `local` parameter to limit the operation to the local peer. - - -##### Go APIs - -There are few changes to Go APIs. The `RepoGC` and `RepoGCLocal` methods have been added, the `mappintracker` module has been removed and the `stateless` module has changed the signature of the constructor. - -##### Other - -The IPFS Proxy now intercepts the `/repo/gc` endpoint and triggers a cluster-wide GC operation. - -The `ipfs-cluster-follow` application is an easy to use way to run one or several cluster peers in follower mode using remote configuration templates. It is fully independent from `ipfs-cluster-service` and `ipfs-cluster-ctl` and acts as both a peer (`run` subcommand) and a client (`list` subcommand). The purpose is to facilitate IPFS Cluster usage without having to deal with the configuration and flags etc. - -That said, the configuration layout and folder is the same for both `ipfs-cluster-service` and `ipfs-cluster-follow` and they can be run one in place of the other. In the same way, remote-source configurations usually used for `ipfs-cluster-follow` can be replaced with local ones usually used by `ipfs-cluster-service`. - -The removal of the `map pintracker` has resulted in a simplification of some operations. `StateSync` (regularly run every `state_sync_interval`) does not trigger repinnings now, but only checks for pin expirations. `RecoverAllLocal` (regularly run every `pin_recover_interval`) will now trigger repinnings when necessary (i.e. when things that were expected to be on IPFS are not). On very large pinsets, this operation can trigger a memory spike as the full recursive pinset from IPFS is requested and loaded on memory (before this happened on `StateSync`). - ---- - -### v0.11.0 - 2019-09-13 - -#### Summary - -IPFS Cluster v0.11.0 is the biggest release in the project's history. Its main -feature is the introduction of the new CRDT "consensus" component. Leveraging -Pubsub, Bitswap and the DHT and using CRDTs, cluster peers can track the -global pinset without needing to be online or worrying about the rest of the -peers as it happens with the original Raft approach. - -The CRDT component brings a lots of features around it, like RPC -authorization, which effectively lets cluster peers run in clusters where only -a trusted subset of nodes can access peer endpoints and made modifications to -the pinsets. - -We have additionally taken lots of steps to improve configuration management -of peers, separating the peer identity from the rest of the configuration and -allowing to use remote configurations fetched from an HTTP url (which may well -be the local IPFS gateway). This allows cluster administrators to provide -the configurations needed for any peers to join a cluster as followers. - -The CRDT arrival incorporates a large number of improvements in peerset -management, bootstrapping, connection management and auto-recovery of peers -after network disconnections. We have improved the peer monitoring system, -added support for efficient Pin-Update-based pinning, reworked timeout control -for pinning and fixed a number of annoying bugs. - -This release is mostly backwards compatible with the previous one and -clusters should keep working with the same configurations, but users should -have a look to the sections below and read the updated documentation, as a -number of changes have been introduced to support both consensus components. - -Consensus selection happens during initialization of the configuration (see -configuration changes below). Migration of the pinset is necessary by doing -`state export` (with Raft configured), followed by `state import` (with CRDT -configured). Note that all peers should be configured with the same consensus -type. - - -#### List of changes - -##### Features - - -* crdt: introduce crdt-based consensus component | [ipfs-cluster/ipfs-cluster#685](https://github.com/ipfs-cluster/ipfs-cluster/issues/685) | [ipfs-cluster/ipfs-cluster#804](https://github.com/ipfs-cluster/ipfs-cluster/issues/804) | [ipfs-cluster/ipfs-cluster#787](https://github.com/ipfs-cluster/ipfs-cluster/issues/787) | [ipfs-cluster/ipfs-cluster#798](https://github.com/ipfs-cluster/ipfs-cluster/issues/798) | [ipfs-cluster/ipfs-cluster#805](https://github.com/ipfs-cluster/ipfs-cluster/issues/805) | [ipfs-cluster/ipfs-cluster#811](https://github.com/ipfs-cluster/ipfs-cluster/issues/811) | [ipfs-cluster/ipfs-cluster#816](https://github.com/ipfs-cluster/ipfs-cluster/issues/816) | [ipfs-cluster/ipfs-cluster#820](https://github.com/ipfs-cluster/ipfs-cluster/issues/820) | [ipfs-cluster/ipfs-cluster#856](https://github.com/ipfs-cluster/ipfs-cluster/issues/856) | [ipfs-cluster/ipfs-cluster#857](https://github.com/ipfs-cluster/ipfs-cluster/issues/857) | [ipfs-cluster/ipfs-cluster#834](https://github.com/ipfs-cluster/ipfs-cluster/issues/834) | [ipfs-cluster/ipfs-cluster#856](https://github.com/ipfs-cluster/ipfs-cluster/issues/856) | [ipfs-cluster/ipfs-cluster#867](https://github.com/ipfs-cluster/ipfs-cluster/issues/867) | [ipfs-cluster/ipfs-cluster#874](https://github.com/ipfs-cluster/ipfs-cluster/issues/874) | [ipfs-cluster/ipfs-cluster#885](https://github.com/ipfs-cluster/ipfs-cluster/issues/885) | [ipfs-cluster/ipfs-cluster#899](https://github.com/ipfs-cluster/ipfs-cluster/issues/899) | [ipfs-cluster/ipfs-cluster#906](https://github.com/ipfs-cluster/ipfs-cluster/issues/906) | [ipfs-cluster/ipfs-cluster#918](https://github.com/ipfs-cluster/ipfs-cluster/issues/918) -* configs: separate identity and configuration | [ipfs-cluster/ipfs-cluster#760](https://github.com/ipfs-cluster/ipfs-cluster/issues/760) | [ipfs-cluster/ipfs-cluster#766](https://github.com/ipfs-cluster/ipfs-cluster/issues/766) | [ipfs-cluster/ipfs-cluster#780](https://github.com/ipfs-cluster/ipfs-cluster/issues/780) -* configs: support running with a remote `service.json` (http) | [ipfs-cluster/ipfs-cluster#868](https://github.com/ipfs-cluster/ipfs-cluster/issues/868) -* configs: support a `follower_mode` option | [ipfs-cluster/ipfs-cluster#803](https://github.com/ipfs-cluster/ipfs-cluster/issues/803) | [ipfs-cluster/ipfs-cluster#864](https://github.com/ipfs-cluster/ipfs-cluster/issues/864) -* service/configs: do not load API components if no config present | [ipfs-cluster/ipfs-cluster#452](https://github.com/ipfs-cluster/ipfs-cluster/issues/452) | [ipfs-cluster/ipfs-cluster#836](https://github.com/ipfs-cluster/ipfs-cluster/issues/836) -* service: add `ipfs-cluster-service init --peers` flag to initialize with given peers | [ipfs-cluster/ipfs-cluster#835](https://github.com/ipfs-cluster/ipfs-cluster/issues/835) | [ipfs-cluster/ipfs-cluster#839](https://github.com/ipfs-cluster/ipfs-cluster/issues/839) | [ipfs-cluster/ipfs-cluster#870](https://github.com/ipfs-cluster/ipfs-cluster/issues/870) -* cluster: RPC auth: block rpc endpoints for non trusted peers | [ipfs-cluster/ipfs-cluster#775](https://github.com/ipfs-cluster/ipfs-cluster/issues/775) | [ipfs-cluster/ipfs-cluster#710](https://github.com/ipfs-cluster/ipfs-cluster/issues/710) | [ipfs-cluster/ipfs-cluster#666](https://github.com/ipfs-cluster/ipfs-cluster/issues/666) | [ipfs-cluster/ipfs-cluster#773](https://github.com/ipfs-cluster/ipfs-cluster/issues/773) | [ipfs-cluster/ipfs-cluster#905](https://github.com/ipfs-cluster/ipfs-cluster/issues/905) -* cluster: introduce connection manager | [ipfs-cluster/ipfs-cluster#791](https://github.com/ipfs-cluster/ipfs-cluster/issues/791) -* cluster: support new `PinUpdate` option for new pins | [ipfs-cluster/ipfs-cluster#869](https://github.com/ipfs-cluster/ipfs-cluster/issues/869) | [ipfs-cluster/ipfs-cluster#732](https://github.com/ipfs-cluster/ipfs-cluster/issues/732) -* cluster: trigger `Recover` automatically on a configurable interval | [ipfs-cluster/ipfs-cluster#831](https://github.com/ipfs-cluster/ipfs-cluster/issues/831) | [ipfs-cluster/ipfs-cluster#887](https://github.com/ipfs-cluster/ipfs-cluster/issues/887) -* cluster: enable mDNS discovery for peers | [ipfs-cluster/ipfs-cluster#882](https://github.com/ipfs-cluster/ipfs-cluster/issues/882) | [ipfs-cluster/ipfs-cluster#900](https://github.com/ipfs-cluster/ipfs-cluster/issues/900) -* IPFS Proxy: Support `pin/update` | [ipfs-cluster/ipfs-cluster#732](https://github.com/ipfs-cluster/ipfs-cluster/issues/732) | [ipfs-cluster/ipfs-cluster#768](https://github.com/ipfs-cluster/ipfs-cluster/issues/768) | [ipfs-cluster/ipfs-cluster#887](https://github.com/ipfs-cluster/ipfs-cluster/issues/887) -* monitor: Accrual failure detection.

-#### Upgrading notices - - -##### Configuration changes - -This release introduces a number of backwards-compatible configuration changes: - -* The `service.json` file no longer includes `ID` and `PrivateKey`, which are - now part of an `identity.json` file. However things should work as before if - they do. Running `ipfs-cluster-service daemon` on a older configuration will - automatically write an `identity.json` file with the old credentials so that - things do not break when the compatibility hack is removed. - -* The `service.json` can use a new single top-level `source` field which can - be set to an HTTP url pointing to a full `service.json`. When present, - this will be read and used when starting the daemon. `ipfs-cluster-service - init http://url` produces this type of "remote configuration" file. - -* `cluster` section: - * A new, hidden `follower_mode` option has been introduced in the main - `cluster` configuration section. When set, the cluster peer will provide - clear errors when pinning or unpinning. This is a UI feature. The capacity - of a cluster peer to pin/unpin depends on whether it is trusted by other - peers, not on settin this hidden option. - * A new `pin_recover_interval` option to controls how often pins in error - states are retried. - * A new `mdns_interval` controls the time between mDNS broadcasts to - discover other peers in the network. Setting it to 0 disables mDNS - altogether (default is 10 seconds). - * A new `connection_manager` object can be used to limit the number of - connections kept by the libp2p host: - -```js -"connection_manager": { - "high_water": 400, - "low_water": 100, - "grace_period": "2m0s" -}, -``` - - -* `consensus` section: - * Only one configuration object is allowed inside the `consensus` section, - and it must be either the `crdt` or the `raft` one. The presence of one or - another is used to autoselect the consensus component to be used when - running the daemon or performing `ipfs-cluster-service state` - operations. `ipfs-cluster-service init` receives an optional `--consensus` - flag to select which one to produce. By default it is the `crdt`. - -* `ipfs_connector/ipfshttp` section: - * The `pin_timeout` in the `ipfshttp` section is now starting from the last - block received. Thus it allows more flexibility for things which are - pinning very slowly, but still pinning. - * The `pin_method` option has been removed, as go-ipfs does not do a - pin-global-lock anymore. Therefore `pin add` will be called directly, can - be called multiple times in parallel and should be faster than the - deprecated `refs -r` way. - * The `ipfshttp` section has a new (hidden) `unpin_disable` option - (boolean). The component will refuse to unpin anything from IPFS when - enabled. It can be used as a failsafe option to make sure cluster peers - never unpin content. - -* `datastore` section: - * The configuration has a new `datastore/badger` section, which is relevant - when using the `crdt` consensus component. It allows full control of the - [Badger configuration](https://godoc.org/github.com/dgraph-io/badger#Options), - which is particuarly important when running on systems with low memory: - - -``` - "datastore": { - "badger": { - "badger_options": { - "dir": "", - "value_dir": "", - "sync_writes": true, - "table_loading_mode": 2, - "value_log_loading_mode": 2, - "num_versions_to_keep": 1, - "max_table_size": 67108864, - "level_size_multiplier": 10, - "max_levels": 7, - "value_threshold": 32, - "num_memtables": 5, - "num_level_zero_tables": 5, - "num_level_zero_tables_stall": 10, - "level_one_size": 268435456, - "value_log_file_size": 1073741823, - "value_log_max_entries": 1000000, - "num_compactors": 2, - "compact_l_0_on_close": true, - "read_only": false, - "truncate": false - } - } - } -``` - -* `pin_tracker/maptracker` section: - * The `max_pin_queue_size` parameter has been hidden for default - configurations and the default has been set to 1000000. - -* `api/restapi` section: - * A new `http_log_file` options allows to redirect the REST API logging to a - file. Otherwise, it is logged as part of the regular log. Lines follow the - Apache Common Log Format (CLF). - -##### REST API - -The `POST /pins/{cid}` and `DELETE /pins/{cid}` now returns a pin object with -`200 Success` rather than an empty `204 Accepted` response. - -Using an unexistent route will now correctly return a JSON object along with -the 404 HTTP code, rather than text. - -##### Go APIs - -There have been some changes to Go APIs. Applications integrating Cluster -directly will be affected by the new signatures of Pin/Unpin: - -* The `Pin` and `Unpin` methods now return an object of `api.Pin` type, along with an error. -* The `Pin` method takes a CID and `PinOptions` rather than an `api.Pin` object wrapping -those. -* A new `PinUpdate` method has been introduced. - -Additionally: - -* The Consensus Component interface has changed to accommodate peer-trust operations. -* The IPFSConnector Component interface `Pin` method has changed to take an `api.Pin` type. - - -##### Other - -* The IPFS Proxy now hijacks the `/api/v0/pin/update` and makes a Cluster PinUpdate. -* `ipfs-cluster-service init` now takes a `--consensus` flag to select between - `crdt` (default) and `raft`. Depending on the values, the generated - configuration will have the relevant sections for each. -* The Dockerfiles have been updated to: - * Support the `IPFS_CLUSTER_CONSENSUS` flag to determine which consensus to - use for the automatic `init`. - * No longer use `IPFS_API` environment variable to do a `sed` replacement on - the config, as `CLUSTER_IPFSHTTP_NODEMULTIADDRESS` is the canonical one to - use. - * No longer use `sed` replacement to set the APIs listen IPs to `0.0.0.0` - automatically, as this can be achieved with environment variables - (`CLUSTER_RESTAPI_HTTPLISTENMULTIADDRESS` and - `CLUSTER_IPFSPROXY_LISTENMULTIADDRESS`) and can be dangerous for containers - running in `net=host` mode. - * The `docker-compose.yml` has been updated and simplified to launch a CRDT - 3-peer TEST cluster -* Cluster now uses `/p2p/` instead of `/ipfs/` for libp2p multiaddresses by - default, but both protocol IDs are equivalent and interchangeable. -* Pinning an already existing pin will re-submit it to the consensus layer in - all cases, meaning that pins in error states will start pinning again - (before, sometimes this was only possible using recover). Recover stays as a - broadcast/sync operation to trigger pinning on errored items. As a reminder, - pin is consensus/async operation. - ---- - - -### v0.10.1 - 2019-04-10 - -#### Summary - -This release is a maintenance release with a number of bug fixes and a couple of small features. - - -#### List of changes - -##### Features - -* Switch to go.mod | [ipfs-cluster/ipfs-cluster#706](https://github.com/ipfs-cluster/ipfs-cluster/issues/706) | [ipfs-cluster/ipfs-cluster#707](https://github.com/ipfs-cluster/ipfs-cluster/issues/707) | [ipfs-cluster/ipfs-cluster#708](https://github.com/ipfs-cluster/ipfs-cluster/issues/708) -* Remove basic monitor | [ipfs-cluster/ipfs-cluster#689](https://github.com/ipfs-cluster/ipfs-cluster/issues/689) | [ipfs-cluster/ipfs-cluster#726](https://github.com/ipfs-cluster/ipfs-cluster/issues/726) -* Support `nocopy` when adding URLs | [ipfs-cluster/ipfs-cluster#735](https://github.com/ipfs-cluster/ipfs-cluster/issues/735) - -##### Bug fixes - -* Mitigate long header attack | [ipfs-cluster/ipfs-cluster#636](https://github.com/ipfs-cluster/ipfs-cluster/issues/636) | [ipfs-cluster/ipfs-cluster#712](https://github.com/ipfs-cluster/ipfs-cluster/issues/712) -* Fix download link in README | [ipfs-cluster/ipfs-cluster#723](https://github.com/ipfs-cluster/ipfs-cluster/issues/723) -* Fix `peers ls` error when peers down | [ipfs-cluster/ipfs-cluster#715](https://github.com/ipfs-cluster/ipfs-cluster/issues/715) | [ipfs-cluster/ipfs-cluster#719](https://github.com/ipfs-cluster/ipfs-cluster/issues/719) -* Nil pointer panic on `ipfs-cluster-ctl add` | [ipfs-cluster/ipfs-cluster#727](https://github.com/ipfs-cluster/ipfs-cluster/issues/727) | [ipfs-cluster/ipfs-cluster#728](https://github.com/ipfs-cluster/ipfs-cluster/issues/728) -* Fix `enc=json` output on `ipfs-cluster-ctl add` | [ipfs-cluster/ipfs-cluster#729](https://github.com/ipfs-cluster/ipfs-cluster/issues/729) -* Add SSL CAs to Docker container | [ipfs-cluster/ipfs-cluster#730](https://github.com/ipfs-cluster/ipfs-cluster/issues/730) | [ipfs-cluster/ipfs-cluster#731](https://github.com/ipfs-cluster/ipfs-cluster/issues/731) -* Remove duplicate import | [ipfs-cluster/ipfs-cluster#734](https://github.com/ipfs-cluster/ipfs-cluster/issues/734) -* Fix version json object | [ipfs-cluster/ipfs-cluster#743](https://github.com/ipfs-cluster/ipfs-cluster/issues/743) | [ipfs-cluster/ipfs-cluster#752](https://github.com/ipfs-cluster/ipfs-cluster/issues/752) - -#### Upgrading notices - - - -##### Configuration changes - -There are no configuration changes on this release. - -##### REST API - -The `/version` endpoint now returns a version object with *lowercase* `version` key. - -##### Go APIs - -There are no changes to the Go APIs. - -##### Other - -Since we have switched to Go modules for dependency management, `gx` is no -longer used and the maintenance of Gx dependencies has been dropped.

This is the last -upgrade in this fashion as we turn to go-datastore-based storage. The next -release of IPFS Cluster will not understand or be able to upgrade anything -below 0.10.0. - -Secondly, we have made some changes to internal types that should greatly -improve performance a lot, particularly calls involving large collections of -items (`pin ls` or `status`). There are also changes on how the state is -serialized, avoiding unnecessary in-memory copies. We have also upgraded the -dependency stack, incorporating many fixes from libp2p. - -Thirdly, our new great features: - -* `ipfs-cluster-ctl pin add/rm` now supports IPFS paths (`/ipfs/Qmxx.../...`, - `/ipns/Qmxx.../...`, `/ipld/Qm.../...`) which are resolved automatically - before pinning. -* All our configuration values can now be set via environment variables, and -these will be reflected when initializing a new configuration file. -* Pins can now specify a list of "priority allocations". This allows to pin -items to specific Cluster peers, overriding the default allocation policy. -* Finally, the REST API supports adding custom metadata entries as `key=value` - (we will soon add support in `ipfs-cluster-ctl`). Metadata can be added as - query arguments to the Pin or PinPath endpoints: `POST - /pins/?meta-key1=value1&meta-key2=value2...` - -Note that on this release we have also removed a lot of backwards-compatibility -code for things older than version 0.8.0, which kept things working but -printed respective warnings. If you're upgrading from an old release, consider -comparing your configuration with the new default one. - - -#### List of changes - -##### Features - - * Add full support for environment variables in configurations and initialization | [ipfs-cluster/ipfs-cluster#656](https://github.com/ipfs-cluster/ipfs-cluster/issues/656) | [ipfs-cluster/ipfs-cluster#663](https://github.com/ipfs-cluster/ipfs-cluster/issues/663) | [ipfs-cluster/ipfs-cluster#667](https://github.com/ipfs-cluster/ipfs-cluster/issues/667) - * Switch to codecov | [ipfs-cluster/ipfs-cluster#683](https://github.com/ipfs-cluster/ipfs-cluster/issues/683) - * Add auto-resolving IPFS paths | [ipfs-cluster/ipfs-cluster#450](https://github.com/ipfs-cluster/ipfs-cluster/issues/450) | [ipfs-cluster/ipfs-cluster#634](https://github.com/ipfs-cluster/ipfs-cluster/issues/634) - * Support user-defined allocations | [ipfs-cluster/ipfs-cluster#646](https://github.com/ipfs-cluster/ipfs-cluster/issues/646) | [ipfs-cluster/ipfs-cluster#647](https://github.com/ipfs-cluster/ipfs-cluster/issues/647) - * Support user-defined metadata in pin objects | [ipfs-cluster/ipfs-cluster#681](https://github.com/ipfs-cluster/ipfs-cluster/issues/681) - * Make normal types serializable and remove `*Serial` types | [ipfs-cluster/ipfs-cluster#654](https://github.com/ipfs-cluster/ipfs-cluster/issues/654) | [ipfs-cluster/ipfs-cluster#688](https://github.com/ipfs-cluster/ipfs-cluster/issues/688) | [ipfs-cluster/ipfs-cluster#700](https://github.com/ipfs-cluster/ipfs-cluster/issues/700) - * Support IPFS paths in the IPFS proxy | [ipfs-cluster/ipfs-cluster#480](https://github.com/ipfs-cluster/ipfs-cluster/issues/480) | [ipfs-cluster/ipfs-cluster#690](https://github.com/ipfs-cluster/ipfs-cluster/issues/690) - * Use go-datastore as backend for the cluster state | [ipfs-cluster/ipfs-cluster#655](https://github.com/ipfs-cluster/ipfs-cluster/issues/655) - * Upgrade dependencies | [ipfs-cluster/ipfs-cluster#675](https://github.com/ipfs-cluster/ipfs-cluster/issues/675) | [ipfs-cluster/ipfs-cluster#679](https://github.com/ipfs-cluster/ipfs-cluster/issues/679) | [ipfs-cluster/ipfs-cluster#686](https://github.com/ipfs-cluster/ipfs-cluster/issues/686) | [ipfs-cluster/ipfs-cluster#687](https://github.com/ipfs-cluster/ipfs-cluster/issues/687) - * Adopt MIT+Apache 2 License (no more sign-off required) | [ipfs-cluster/ipfs-cluster#692](https://github.com/ipfs-cluster/ipfs-cluster/issues/692) - * Add codecov configurtion file | [ipfs-cluster/ipfs-cluster#693](https://github.com/ipfs-cluster/ipfs-cluster/issues/693) - * Additional tests for basic auth | [ipfs-cluster/ipfs-cluster#645](https://github.com/ipfs-cluster/ipfs-cluster/issues/645) | [ipfs-cluster/ipfs-cluster#694](https://github.com/ipfs-cluster/ipfs-cluster/issues/694) - -##### Bug fixes - - * Fix docker compose tests | [ipfs-cluster/ipfs-cluster#696](https://github.com/ipfs-cluster/ipfs-cluster/issues/696) - * Hide `ipfsproxy.extract_headers_ttl` and `ipfsproxy.extract_headers_path` options by default | [ipfs-cluster/ipfs-cluster#699](https://github.com/ipfs-cluster/ipfs-cluster/issues/699) - -#### Upgrading notices - -This release needs an state upgrade before starting the Cluster daemon.

They are -in the form: - -`CLUSTER_COMPONENTNAME_KEYNAMEWITHOUTSPACES=value` - -Environment variables will override `service.json` configuration options when -defined and the Cluster peer is started. `ipfs-cluster-service init` will -reflect the value of any existing environment variables in the new -`service.json` file. - -##### REST API - -The main breaking change to the REST API corresponds to the JSON -representation of CIDs in response objects: - -* Before: `"cid": "Qm...."` -* Now: `"cid": { "/": "Qm...."}` - -The new CID encoding is the default as defined by the `cid` -library. Unfortunately, there is no good solution to keep the previous -representation without copying all the objects (an innefficient technique we -just removed). The new CID encoding is otherwise aligned with the rest of the -stack. - -The API also gets two new "Path" endpoints: - -* `POST /pins///...` and -* `DELETE /pins///...` - -Thus, it is equivalent to pin a CID with `POST /pins/` (as before) or -with `POST /pins/ipfs/`. - -The calls will however fail when a non-compliant IPFS path is provided: `POST -/pins//my/path` will fail because all paths must start with the `/ipfs`, -`/ipns` or `/ipld` components. - -##### Go APIs - -This release introduces lots of changes to the Go APIs, including the Go REST -API client, as we have started returning pointers to objects rather than the -objects directly. The `Pin` will now take `api.PinOptions` instead of -different arguments corresponding to the options. It is aligned with the new -`PinPath` and `UnpinPath`. - -##### Other - -As pointed above, 0.10.0's state migration is a required step to be able to -use future version of IPFS Cluster. - ---- - -### v0.9.0 - 2019-02-18 - -#### Summary - -IPFS Cluster version 0.9.0 comes with one big new feature, [OpenCensus](https://opencensus.io) support! This allows for the collection of distributed traces and metrics from the IPFS Cluster application as well as supporting libraries. Currently, we support the use of [Jaeger](https://jaegertracing.io) as the tracing backend and [Prometheus](https://prometheus.io) as the metrics backend. Support for other [OpenCensus backends](https://opencensus.io/exporters/) will be added as requested by the community. - -#### List of changes - -##### Features - - * Integrate [OpenCensus](https://opencensus.io) tracing and metrics into IPFS Cluster codebase | [ipfs-cluster/ipfs-cluster#486](https://github.com/ipfs-cluster/ipfs-cluster/issues/486) | [ipfs-cluster/ipfs-cluster#658](https://github.com/ipfs-cluster/ipfs-cluster/issues/658) | [ipfs-cluster/ipfs-cluster#659](https://github.com/ipfs-cluster/ipfs-cluster/issues/659) | [ipfs-cluster/ipfs-cluster#676](https://github.com/ipfs-cluster/ipfs-cluster/issues/676) | [ipfs-cluster/ipfs-cluster#671](https://github.com/ipfs-cluster/ipfs-cluster/issues/671) | [ipfs-cluster/ipfs-cluster#674](https://github.com/ipfs-cluster/ipfs-cluster/issues/674) - -##### Bug Fixes - -No bugs were fixed from the previous release. - -##### Deprecated - - * The snap distribution of IPFS Cluster has been removed | [ipfs-cluster/ipfs-cluster#593](https://github.com/ipfs-cluster/ipfs-cluster/issues/593) | [ipfs-cluster/ipfs-cluster#649](https://github.com/ipfs-cluster/ipfs-cluster/issues/649). - -#### Upgrading notices - -##### Configuration changes - -No changes to the existing configuration. - -There are two new configuration sections with this release: - -###### `tracing` section - -The `tracing` section configures the use of Jaeger as a tracing backend. - -```js - "tracing": { - "enable_tracing": false, - "jaeger_agent_endpoint": "/ip4/0.0.0.0/udp/6831", - "sampling_prob": 0.3, - "service_name": "cluster-daemon" - } -``` - -###### `metrics` section - -The `metrics` section configures the use of Prometheus as a metrics collector. - -```js - "metrics": { - "enable_stats": false, - "prometheus_endpoint": "/ip4/0.0.0.0/tcp/8888", - "reporting_interval": "2s" - } -``` - -##### REST API - -No changes to the REST API. - -##### Go APIs - -The Go APIs had the minor change of having a `context.Context` parameter added as the first argument -to those that didn't already have it.

Check the configuration changes section -below for more information about how this affects the configuration file. - -Finally we have some useful small features: - -* The `ipfs-cluster-ctl status --filter` option allows to just list those -items which are still `pinning` or `queued` or `error` etc. You can combine -multiple filters. This translates to a new `filter` query parameter in the -`/pins` API endpoint. -* The `stream-channels=false` query parameter for the `/add` endpoint will let -the API buffer the output when adding and return a valid JSON array once done, -making this API endpoint behave like a regular, non-streaming one. -`ipfs-cluster-ctl add --no-stream` acts similarly, but buffering on the client -side. Note that this will cause in-memory buffering of potentially very large -responses when the number of added files is very large, but should be -perfectly fine for regular usage. -* The `ipfs-cluster-ctl add --quieter` flag now applies to the JSON output -too, allowing the user to just get the last added entry JSON object when -adding a file, which is always the root hash. - -#### List of changes - -##### Features - - * IPFS Proxy extraction to its own `API` component: `ipfsproxy` | [ipfs-cluster/ipfs-cluster#453](https://github.com/ipfs-cluster/ipfs-cluster/issues/453) | [ipfs-cluster/ipfs-cluster#576](https://github.com/ipfs-cluster/ipfs-cluster/issues/576) | [ipfs-cluster/ipfs-cluster#616](https://github.com/ipfs-cluster/ipfs-cluster/issues/616) | [ipfs-cluster/ipfs-cluster#617](https://github.com/ipfs-cluster/ipfs-cluster/issues/617) - * Add full CORS handling to `restapi` | [ipfs-cluster/ipfs-cluster#639](https://github.com/ipfs-cluster/ipfs-cluster/issues/639) | [ipfs-cluster/ipfs-cluster#640](https://github.com/ipfs-cluster/ipfs-cluster/issues/640) - * `restapi` configuration section entries can be overridden from environment variables | [ipfs-cluster/ipfs-cluster#609](https://github.com/ipfs-cluster/ipfs-cluster/issues/609) - * Update to `go-ipfs-files` 2.0 | [ipfs-cluster/ipfs-cluster#613](https://github.com/ipfs-cluster/ipfs-cluster/issues/613) - * Tests for the `/monitor/metrics` endpoint | [ipfs-cluster/ipfs-cluster#587](https://github.com/ipfs-cluster/ipfs-cluster/issues/587) | [ipfs-cluster/ipfs-cluster#622](https://github.com/ipfs-cluster/ipfs-cluster/issues/622) - * Support `stream-channels=fase` query parameter in `/add` | [ipfs-cluster/ipfs-cluster#632](https://github.com/ipfs-cluster/ipfs-cluster/issues/632) | [ipfs-cluster/ipfs-cluster#633](https://github.com/ipfs-cluster/ipfs-cluster/issues/633) - * Support server side `/pins` filtering | [ipfs-cluster/ipfs-cluster#445](https://github.com/ipfs-cluster/ipfs-cluster/issues/445) | [ipfs-cluster/ipfs-cluster#478](https://github.com/ipfs-cluster/ipfs-cluster/issues/478) | [ipfs-cluster/ipfs-cluster#627](https://github.com/ipfs-cluster/ipfs-cluster/issues/627) - * `ipfs-cluster-ctl add --no-stream` option | [ipfs-cluster/ipfs-cluster#632](https://github.com/ipfs-cluster/ipfs-cluster/issues/632) | [ipfs-cluster/ipfs-cluster#637](https://github.com/ipfs-cluster/ipfs-cluster/issues/637) - * Upgrade dependencies and libp2p to version 6.0.29 | [ipfs-cluster/ipfs-cluster#624](https://github.com/ipfs-cluster/ipfs-cluster/issues/624) - -##### Bug fixes - - * Respect IPFS daemon response headers on non-proxied calls | [ipfs-cluster/ipfs-cluster#382](https://github.com/ipfs-cluster/ipfs-cluster/issues/382) | [ipfs-cluster/ipfs-cluster#623](https://github.com/ipfs-cluster/ipfs-cluster/issues/623) | [ipfs-cluster/ipfs-cluster#638](https://github.com/ipfs-cluster/ipfs-cluster/issues/638) - * Fix `ipfs-cluster-ctl` usage with HTTPs and `/dns*` hostnames | [ipfs-cluster/ipfs-cluster#626](https://github.com/ipfs-cluster/ipfs-cluster/issues/626) - * Minor fixes in sharness | [ipfs-cluster/ipfs-cluster#641](https://github.com/ipfs-cluster/ipfs-cluster/issues/641) | [ipfs-cluster/ipfs-cluster#643](https://github.com/ipfs-cluster/ipfs-cluster/issues/643) - * Fix error handling when parsing the configuration | [ipfs-cluster/ipfs-cluster#642](https://github.com/ipfs-cluster/ipfs-cluster/issues/642) - - - -#### Upgrading notices - -This release comes with some configuration changes that are important to notice, -even though the peers will start with the same configurations as before. - -##### Configuration changes - -##### `ipfsproxy` section - -This version introduces a separate `ipfsproxy` API component. This is -reflected in the `service.json` configuration, which now includes a new -`ipfsproxy` subsection under the `api` section. By default it looks like: - -```js - "ipfsproxy": { - "node_multiaddress": "/ip4/127.0.0.1/tcp/5001", - "listen_multiaddress": "/ip4/127.0.0.1/tcp/9095", - "read_timeout": "0s", - "read_header_timeout": "5s", - "write_timeout": "0s", - "idle_timeout": "1m0s" - } -``` - -We have however added the necessary safeguards to keep backwards compatibility -for this release. If the `ipfsproxy` section is empty, it will be picked up from -the `ipfshttp` section as before. An ugly warning will be printed in this case. - -Based on the above, the `ipfshttp` configuration section loses the -proxy-related options. Note that `node_multiaddress` stays in both component -configurations and should likely be the same in most cases, but you can now -potentially proxy requests to a different daemon than the one used by the -cluster peer. - -Additional hidden configuration options to manage custom header extraction -from the IPFS daemon (for power users) have been added to the `ipfsproxy` -section but are not shown by default when initializing empty -configurations. See the documentation for more details. - -###### `restapi` section - -The introduction of proper CORS handling in the `restapi` component introduces -a number of new keys: - -```js - "cors_allowed_origins": [ - "*" - ], - "cors_allowed_methods": [ - "GET" - ], - "cors_allowed_headers": [], - "cors_exposed_headers": [ - "Content-Type", - "X-Stream-Output", - "X-Chunked-Output", - "X-Content-Length" - ], - "cors_allow_credentials": true, - "cors_max_age": "0s" -``` - -Note that CORS will be essentially unconfigured when these keys are not -defined. - -The `headers` key, which was used before to add some CORS related headers -manually, takes a new empty default. **We recommend emptying `headers` from -any CORS-related value.** - - -##### REST API - -The REST API is fully backwards compatible: - -* The `GET /pins` endpoint takes a new `?filter=` option. See - `ipfs-cluster-ctl status --help` for acceptable values. -* The `POST /add` endpoint accepts a new `?stream-channels=` - option. By default it is set to `true`. - -##### Go APIs - -The signature for the `StatusAll` method in the REST `client` module has -changed to include a `filter` parameter. - -There may have been other minimal changes to internal exported Go APIs, but -should not affect users. - -##### Other - -Proxy requests which are handled by the Cluster peer (`/pin/ls`, `/pin/add`, -`/pin/rm`, `/repo/stat` and `/add`) will now attempt to fully mimic ipfs -responses to the header level. This is done by triggering CORS pre-flight for -every hijacked request along with an occasional regular request to `/version` -to extract other headers (and possibly custom ones). - -The practical result is that the proxy now behaves correctly when dropped -instead of IPFS into CORS-aware contexts (like the browser). - ---- - -### v0.7.0 - 2018-11-01 - -#### Summary - -IPFS Cluster version 0.7.0 is a maintenance release that includes a few bugfixes and some small features. - -Note that the REST API response format for the `/add` endpoint has changed. Thus all clients need to be upgraded to deal with the new format. The `rest/api/client` has been accordingly updated. - -#### List of changes - -##### Features - - * Clean (rotate) the state when running `init` | [ipfs-cluster/ipfs-cluster#532](https://github.com/ipfs-cluster/ipfs-cluster/issues/532) | [ipfs-cluster/ipfs-cluster#553](https://github.com/ipfs-cluster/ipfs-cluster/issues/553) - * Configurable REST API headers and CORS defaults | [ipfs-cluster/ipfs-cluster#578](https://github.com/ipfs-cluster/ipfs-cluster/issues/578) - * Upgrade libp2p and other deps | [ipfs-cluster/ipfs-cluster#580](https://github.com/ipfs-cluster/ipfs-cluster/issues/580) | [ipfs-cluster/ipfs-cluster#590](https://github.com/ipfs-cluster/ipfs-cluster/issues/590) | [ipfs-cluster/ipfs-cluster#592](https://github.com/ipfs-cluster/ipfs-cluster/issues/592) | [ipfs-cluster/ipfs-cluster#598](https://github.com/ipfs-cluster/ipfs-cluster/issues/598) | [ipfs-cluster/ipfs-cluster#599](https://github.com/ipfs-cluster/ipfs-cluster/issues/599) - * Use `gossipsub` to broadcast metrics | [ipfs-cluster/ipfs-cluster#573](https://github.com/ipfs-cluster/ipfs-cluster/issues/573) - * Download gx and gx-go from IPFS preferentially | [ipfs-cluster/ipfs-cluster#577](https://github.com/ipfs-cluster/ipfs-cluster/issues/577) | [ipfs-cluster/ipfs-cluster#581](https://github.com/ipfs-cluster/ipfs-cluster/issues/581) - * Expose peer metrics in the API + ctl commands | [ipfs-cluster/ipfs-cluster#449](https://github.com/ipfs-cluster/ipfs-cluster/issues/449) | [ipfs-cluster/ipfs-cluster#572](https://github.com/ipfs-cluster/ipfs-cluster/issues/572) | [ipfs-cluster/ipfs-cluster#589](https://github.com/ipfs-cluster/ipfs-cluster/issues/589) | [ipfs-cluster/ipfs-cluster#587](https://github.com/ipfs-cluster/ipfs-cluster/issues/587) - * Add a `docker-compose.yml` template, which creates a two peer cluster | [ipfs-cluster/ipfs-cluster#585](https://github.com/ipfs-cluster/ipfs-cluster/issues/585) | [ipfs-cluster/ipfs-cluster#588](https://github.com/ipfs-cluster/ipfs-cluster/issues/588) - * Support overwriting configuration values in the `cluster` section with environmental values | [ipfs-cluster/ipfs-cluster#575](https://github.com/ipfs-cluster/ipfs-cluster/issues/575) | [ipfs-cluster/ipfs-cluster#596](https://github.com/ipfs-cluster/ipfs-cluster/issues/596) - * Set snaps to `classic` confinement mode and revert it since approval never arrived | [ipfs-cluster/ipfs-cluster#579](https://github.com/ipfs-cluster/ipfs-cluster/issues/579) | [ipfs-cluster/ipfs-cluster#594](https://github.com/ipfs-cluster/ipfs-cluster/issues/594) -* Use Go's reverse proxy library in the proxy endpoint | [ipfs-cluster/ipfs-cluster#570](https://github.com/ipfs-cluster/ipfs-cluster/issues/570) | [ipfs-cluster/ipfs-cluster#605](https://github.com/ipfs-cluster/ipfs-cluster/issues/605) - - -##### Bug fixes - - * `/add` endpoints improvements and IPFS Companion compatibility | [ipfs-cluster/ipfs-cluster#582](https://github.com/ipfs-cluster/ipfs-cluster/issues/582) | [ipfs-cluster/ipfs-cluster#569](https://github.com/ipfs-cluster/ipfs-cluster/issues/569) - * Fix adding with spaces in the name parameter | [ipfs-cluster/ipfs-cluster#583](https://github.com/ipfs-cluster/ipfs-cluster/issues/583) - * Escape filter query parameter | [ipfs-cluster/ipfs-cluster#586](https://github.com/ipfs-cluster/ipfs-cluster/issues/586) - * Fix some race conditions | [ipfs-cluster/ipfs-cluster#597](https://github.com/ipfs-cluster/ipfs-cluster/issues/597) - * Improve pin deserialization efficiency | [ipfs-cluster/ipfs-cluster#601](https://github.com/ipfs-cluster/ipfs-cluster/issues/601) - * Do not error remote pins | [ipfs-cluster/ipfs-cluster#600](https://github.com/ipfs-cluster/ipfs-cluster/issues/600) | [ipfs-cluster/ipfs-cluster#603](https://github.com/ipfs-cluster/ipfs-cluster/issues/603) - * Clean up testing folders in `rest` and `rest/client` after tests | [ipfs-cluster/ipfs-cluster#607](https://github.com/ipfs-cluster/ipfs-cluster/issues/607) - -#### Upgrading notices - -##### Configuration changes - -The configurations from previous versions are compatible, but a new `headers` key has been added to the `restapi` section.

They are handled in the `client`. - -##### Go APIs - -The `AddedOutput` object has changed, thus the `api/rest/client` from older versions will not work with this one. - -##### Other - -No other things. - ---- - -### v0.6.0 - 2018-10-03 - -#### Summary - -IPFS version 0.6.0 is a new minor release of IPFS Cluster. - -We have increased the minor release number to signal changes to the Go APIs after upgrading to the new `cid` package, but, other than that, this release does not include any major changes. - -It brings a number of small fixes and features of which we can highlight two useful ones: - -* the first is the support for multiple cluster daemon versions in the same cluster, as long as they share the same major/minor release. That means, all releases in the `0.6` series (`0.6.0`, `0.6.1` and so on...) will be able to speak among each others, allowing partial cluster upgrades. -* the second is the inclusion of a `PeerName` key in the status (`PinInfo`) objects. `ipfs-cluster-status` will now show peer names instead of peer IDs, making it easy to identify the status for each peer. - -Many thanks to all the contributors to this release: @lanzafame, @meiqimichelle, @kishansagathiya, @cannium, @jglukasik and @mike-ngu. - -#### List of changes - -##### Features - - * Move commands to the `cmd/` folder | [ipfs-cluster/ipfs-cluster#485](https://github.com/ipfs-cluster/ipfs-cluster/issues/485) | [ipfs-cluster/ipfs-cluster#521](https://github.com/ipfs-cluster/ipfs-cluster/issues/521) | [ipfs-cluster/ipfs-cluster#556](https://github.com/ipfs-cluster/ipfs-cluster/issues/556) - * Dependency upgrades: `go-dot`, `go-libp2p`, `cid` | [ipfs-cluster/ipfs-cluster#533](https://github.com/ipfs-cluster/ipfs-cluster/issues/533) | [ipfs-cluster/ipfs-cluster#537](https://github.com/ipfs-cluster/ipfs-cluster/issues/537) | [ipfs-cluster/ipfs-cluster#535](https://github.com/ipfs-cluster/ipfs-cluster/issues/535) | [ipfs-cluster/ipfs-cluster#544](https://github.com/ipfs-cluster/ipfs-cluster/issues/544) | [ipfs-cluster/ipfs-cluster#561](https://github.com/ipfs-cluster/ipfs-cluster/issues/561) - * Build with go-1.11 | [ipfs-cluster/ipfs-cluster#558](https://github.com/ipfs-cluster/ipfs-cluster/issues/558) - * Peer names in `PinInfo` | [ipfs-cluster/ipfs-cluster#446](https://github.com/ipfs-cluster/ipfs-cluster/issues/446) | [ipfs-cluster/ipfs-cluster#531](https://github.com/ipfs-cluster/ipfs-cluster/issues/531) - * Wrap API client in an interface | [ipfs-cluster/ipfs-cluster#447](https://github.com/ipfs-cluster/ipfs-cluster/issues/447) | [ipfs-cluster/ipfs-cluster#523](https://github.com/ipfs-cluster/ipfs-cluster/issues/523) | [ipfs-cluster/ipfs-cluster#564](https://github.com/ipfs-cluster/ipfs-cluster/issues/564) - * `Makefile`: add `prcheck` target and fix `make all` | [ipfs-cluster/ipfs-cluster#536](https://github.com/ipfs-cluster/ipfs-cluster/issues/536) | [ipfs-cluster/ipfs-cluster#542](https://github.com/ipfs-cluster/ipfs-cluster/issues/542) | [ipfs-cluster/ipfs-cluster#539](https://github.com/ipfs-cluster/ipfs-cluster/issues/539) - * Docker: speed up [re]builds | [ipfs-cluster/ipfs-cluster#529](https://github.com/ipfs-cluster/ipfs-cluster/issues/529) - * Re-enable keep-alives on servers | [ipfs-cluster/ipfs-cluster#548](https://github.com/ipfs-cluster/ipfs-cluster/issues/548) | [ipfs-cluster/ipfs-cluster#560](https://github.com/ipfs-cluster/ipfs-cluster/issues/560) - -##### Bugfixes - - * Fix adding to cluster with unhealthy peers | [ipfs-cluster/ipfs-cluster#543](https://github.com/ipfs-cluster/ipfs-cluster/issues/543) | [ipfs-cluster/ipfs-cluster#549](https://github.com/ipfs-cluster/ipfs-cluster/issues/549) - * Fix Snap builds and pushes: multiple architectures re-enabled | [ipfs-cluster/ipfs-cluster#520](https://github.com/ipfs-cluster/ipfs-cluster/issues/520) | [ipfs-cluster/ipfs-cluster#554](https://github.com/ipfs-cluster/ipfs-cluster/issues/554) | [ipfs-cluster/ipfs-cluster#557](https://github.com/ipfs-cluster/ipfs-cluster/issues/557) | [ipfs-cluster/ipfs-cluster#562](https://github.com/ipfs-cluster/ipfs-cluster/issues/562) | [ipfs-cluster/ipfs-cluster#565](https://github.com/ipfs-cluster/ipfs-cluster/issues/565) - * Docs: Typos in Readme and some improvements | [ipfs-cluster/ipfs-cluster#547](https://github.com/ipfs-cluster/ipfs-cluster/issues/547) | [ipfs-cluster/ipfs-cluster#567](https://github.com/ipfs-cluster/ipfs-cluster/issues/567) - * Fix tests in `stateless` PinTracker | [ipfs-cluster/ipfs-cluster#552](https://github.com/ipfs-cluster/ipfs-cluster/issues/552) | [ipfs-cluster/ipfs-cluster#563](https://github.com/ipfs-cluster/ipfs-cluster/issues/563) - -#### Upgrading notices - -##### Configuration changes - -There are no changes to the configuration file on this release. - -##### REST API - -There are no changes to the REST API. - -##### Go APIs - -We have upgraded to the new version of the `cid` package. This means all `*cid.Cid` arguments are now `cid.Cid`. - -##### Other - -We are now using `go-1.11` to build and test cluster. We recommend using this version as well when building from source. - ---- - - -### v0.5.0 - 2018-08-23 - -#### Summary - -IPFS Cluster version 0.5.0 is a minor release which includes a major feature: **adding content to IPFS directly through Cluster**. - -This functionality is provided by `ipfs-cluster-ctl add` and by the API endpoint `/add`. The upload format (multipart) is similar to the IPFS `/add` endpoint, as well as the options (chunker, layout...). Cluster `add` generates the same DAG as `ipfs add` would, but it sends the added blocks directly to their allocations, pinning them on completion. The pin happens very quickly, as content is already locally available in the allocated peers. - -The release also includes most of the needed code for the [Sharding feature](https://ipfscluster.io/developer/rfcs/dag-sharding-rfc/), but it is not yet usable/enabled, pending features from go-ipfs. - -The 0.5.0 release additionally includes a new experimental PinTracker implementation: the `stateless` pin tracker. The stateless pin tracker relies on the IPFS pinset and the cluster state to keep track of pins, rather than keeping an in-memory copy of the cluster pinset, thus reducing the memory usage when having huge pinsets. It can be enabled with `ipfs-cluster-service daemon --pintracker stateless`. - -The last major feature is the use of a DHT as routing layer for cluster peers. This means that peers should be able to discover each others as long as they are connected to one cluster peer. This simplifies the setup requirements for starting a cluster and helps avoiding situations which make the cluster unhealthy. - -This release requires a state upgrade migration. It can be performed with `ipfs-cluster-service state upgrade` or simply launching the daemon with `ipfs-cluster-service daemon --upgrade`. - -#### List of changes - -##### Features - - * Libp2p upgrades (up to v6) | [ipfs-cluster/ipfs-cluster#456](https://github.com/ipfs-cluster/ipfs-cluster/issues/456) | [ipfs-cluster/ipfs-cluster#482](https://github.com/ipfs-cluster/ipfs-cluster/issues/482) - * Support `/dns` multiaddresses for `node_multiaddress` | [ipfs-cluster/ipfs-cluster#462](https://github.com/ipfs-cluster/ipfs-cluster/issues/462) | [ipfs-cluster/ipfs-cluster#463](https://github.com/ipfs-cluster/ipfs-cluster/issues/463) - * Increase `state_sync_interval` to 10 minutes | [ipfs-cluster/ipfs-cluster#468](https://github.com/ipfs-cluster/ipfs-cluster/issues/468) | [ipfs-cluster/ipfs-cluster#469](https://github.com/ipfs-cluster/ipfs-cluster/issues/469) - * Auto-interpret libp2p addresses in `rest/client`'s `APIAddr` configuration option | [ipfs-cluster/ipfs-cluster#498](https://github.com/ipfs-cluster/ipfs-cluster/issues/498) - * Resolve `APIAddr` (for `/dnsaddr` usage) in `rest/client` | [ipfs-cluster/ipfs-cluster#498](https://github.com/ipfs-cluster/ipfs-cluster/issues/498) - * Support for adding content to Cluster and sharding (sharding is disabled) | [ipfs-cluster/ipfs-cluster#484](https://github.com/ipfs-cluster/ipfs-cluster/issues/484) | [ipfs-cluster/ipfs-cluster#503](https://github.com/ipfs-cluster/ipfs-cluster/issues/503) | [ipfs-cluster/ipfs-cluster#495](https://github.com/ipfs-cluster/ipfs-cluster/issues/495) | [ipfs-cluster/ipfs-cluster#504](https://github.com/ipfs-cluster/ipfs-cluster/issues/504) | [ipfs-cluster/ipfs-cluster#509](https://github.com/ipfs-cluster/ipfs-cluster/issues/509) | [ipfs-cluster/ipfs-cluster#511](https://github.com/ipfs-cluster/ipfs-cluster/issues/511) | [ipfs-cluster/ipfs-cluster#518](https://github.com/ipfs-cluster/ipfs-cluster/issues/518) - * `stateless` PinTracker [ipfs-cluster/ipfs-cluster#308](https://github.com/ipfs-cluster/ipfs-cluster/issues/308) | [ipfs-cluster/ipfs-cluster#460](https://github.com/ipfs-cluster/ipfs-cluster/issues/460) - * Add `size-only=true` to `repo/stat` calls | [ipfs-cluster/ipfs-cluster#507](https://github.com/ipfs-cluster/ipfs-cluster/issues/507) - * Enable DHT-based peer discovery and routing for cluster peers | [ipfs-cluster/ipfs-cluster#489](https://github.com/ipfs-cluster/ipfs-cluster/issues/489) | [ipfs-cluster/ipfs-cluster#508](https://github.com/ipfs-cluster/ipfs-cluster/issues/508) - * Gx-go upgrade | [ipfs-cluster/ipfs-cluster#517](https://github.com/ipfs-cluster/ipfs-cluster/issues/517) - -##### Bugfixes - - * Fix type for constants | [ipfs-cluster/ipfs-cluster#455](https://github.com/ipfs-cluster/ipfs-cluster/issues/455) - * Gofmt fix | [ipfs-cluster/ipfs-cluster#464](https://github.com/ipfs-cluster/ipfs-cluster/issues/464) - * Fix tests for forked repositories | [ipfs-cluster/ipfs-cluster#465](https://github.com/ipfs-cluster/ipfs-cluster/issues/465) | [ipfs-cluster/ipfs-cluster#472](https://github.com/ipfs-cluster/ipfs-cluster/issues/472) - * Fix resolve panic on `rest/client` | [ipfs-cluster/ipfs-cluster#498](https://github.com/ipfs-cluster/ipfs-cluster/issues/498) - * Fix remote pins stuck in error state | [ipfs-cluster/ipfs-cluster#500](https://github.com/ipfs-cluster/ipfs-cluster/issues/500) | [ipfs-cluster/ipfs-cluster#460](https://github.com/ipfs-cluster/ipfs-cluster/issues/460) - * Fix running some tests with `-race` | [ipfs-cluster/ipfs-cluster#340](https://github.com/ipfs-cluster/ipfs-cluster/issues/340) | [ipfs-cluster/ipfs-cluster#458](https://github.com/ipfs-cluster/ipfs-cluster/issues/458) - * Fix ipfs proxy `/add` endpoint | [ipfs-cluster/ipfs-cluster#495](https://github.com/ipfs-cluster/ipfs-cluster/issues/495) | [ipfs-cluster/ipfs-cluster#81](https://github.com/ipfs-cluster/ipfs-cluster/issues/81) | [ipfs-cluster/ipfs-cluster#505](https://github.com/ipfs-cluster/ipfs-cluster/issues/505) - * Fix ipfs proxy not hijacking `repo/stat` | [ipfs-cluster/ipfs-cluster#466](https://github.com/ipfs-cluster/ipfs-cluster/issues/466) | [ipfs-cluster/ipfs-cluster#514](https://github.com/ipfs-cluster/ipfs-cluster/issues/514) - * Fix some godoc comments | [ipfs-cluster/ipfs-cluster#519](https://github.com/ipfs-cluster/ipfs-cluster/issues/519) - -#### Upgrading notices - -##### Configuration files - -**IMPORTANT**: `0s` is the new default for the `read_timeout` and `write_timeout` values in the `restapi` configuration section, as well as `proxy_read_timeout` and `proxy_write_timeout` options in the `ipfshttp` section. Adding files to cluster (via the REST api or the proxy) is likely to timeout otherwise. - -The `peerstore` file (in the configuration folder), no longer requires listing the multiaddresses for all cluster peers when initializing the cluster with a fixed peerset. It only requires the multiaddresses for one other cluster peer. The rest will be inferred using the DHT. The peerstore file is updated only on clean shutdown, and will store all known multiaddresses, even if not pertaining to cluster peers. - -The new `stateless` PinTracker implementation uses a new configuration subsection in the `pin_tracker` key. This is only generated with `ipfs-cluster-service init`. When not present, a default configuration will be used (and a warning printed). - -The `state_sync_interval` default has been increased to 10 minutes, as frequent syncing is not needed with the improvements in the PinTracker. Users are welcome to update this setting. - - -##### REST API - -The `/add` endpoint has been added. The `replication_factor_min` and `replication_factor_max` options (in `POST allocations/`) have been deprecated and subsititued for `replication-min` and `replication-max`, although backwards comaptibility is kept. - -Keep Alive has been disabled for the HTTP servers, as a bug in Go's HTTP client implementation may result adding corrupted content (and getting corrupted DAGs). However, while the libp2p API endpoint also suffers this, it will only close libp2p streams. Thus the performance impact on the libp2p-http endpoint should be minimal. - -##### Go APIs - -The `Config.PeerAddr` key in the `rest/client` module is deprecated. `APIAddr` should be used for both HTTP and LibP2P API endpoints. The type of address is automatically detected. - -The IPFSConnector `Pin` call now receives an integer instead of a `Recursive` flag. It indicates the maximum depth to which something should be pinned. The only supported value is `-1` (meaning recursive). `BlockGet` and `BlockPut` calls have been added to the IPFSConnector component. - -##### Other - -As noted above, upgrade to `state` format version 5 is needed before starting the cluster service. - ---- - -### v0.4.0 - 2018-05-30 - -#### Summary - -The IPFS Cluster version 0.4.0 includes breaking changes and a considerable number of new features causing them. The documentation (particularly that affecting the configuration and startup of peers) has been updated accordingly in https://ipfscluster.io . Be sure to also read it if you are upgrading. - -There are four main developments in this release: - -* Refactorings around the `consensus` component, removing dependencies to the main component and allowing separate initialization: this has prompted to re-approach how we handle the peerset, the peer addresses and the peer's startup when using bootstrap. We have gained finer control of Raft, which has allowed us to provide a clearer configuration and a better start up procedure, specially when bootstrapping. The configuration file no longer mutates while cluster is running. -* Improvements to the `pintracker`: our pin tracker is now able to cancel ongoing pins when receiving an unpin request for the same CID, and vice-versa. It will also optimize multiple pin requests (by only queuing and triggering them once) and can now report -whether an item is pinning (a request to ipfs is ongoing) vs. pin-queued (waiting for a worker to perform the request to ipfs). -* Broadcasting of monitoring metrics using PubSub: we have added a new `monitor` implementation that uses PubSub (rather than RPC broadcasting). With the upcoming improvements to PubSub this means that we can do efficient broadcasting of metrics while at the same time not requiring peers to have RPC permissions, which is preparing the ground for collaborative clusters. -* We have launched the IPFS Cluster website: https://ipfscluster.io . We moved most of the documentation over there, expanded it and updated it. - -#### List of changes - -##### Features - - * Consensus refactorings | [ipfs-cluster/ipfs-cluster#398](https://github.com/ipfs-cluster/ipfs-cluster/issues/398) | [ipfs-cluster/ipfs-cluster#371](https://github.com/ipfs-cluster/ipfs-cluster/issues/371) - * Pintracker revamp | [ipfs-cluster/ipfs-cluster#308](https://github.com/ipfs-cluster/ipfs-cluster/issues/308) | [ipfs-cluster/ipfs-cluster#383](https://github.com/ipfs-cluster/ipfs-cluster/issues/383) | [ipfs-cluster/ipfs-cluster#408](https://github.com/ipfs-cluster/ipfs-cluster/issues/408) | [ipfs-cluster/ipfs-cluster#415](https://github.com/ipfs-cluster/ipfs-cluster/issues/415) | [ipfs-cluster/ipfs-cluster#421](https://github.com/ipfs-cluster/ipfs-cluster/issues/421) | [ipfs-cluster/ipfs-cluster#427](https://github.com/ipfs-cluster/ipfs-cluster/issues/427) | [ipfs-cluster/ipfs-cluster#432](https://github.com/ipfs-cluster/ipfs-cluster/issues/432) - * Pubsub monitoring | [ipfs-cluster/ipfs-cluster#400](https://github.com/ipfs-cluster/ipfs-cluster/issues/400) - * Force killing cluster with double CTRL-C | [ipfs-cluster/ipfs-cluster#258](https://github.com/ipfs-cluster/ipfs-cluster/issues/258) | [ipfs-cluster/ipfs-cluster#358](https://github.com/ipfs-cluster/ipfs-cluster/issues/358) - * 3x faster testsuite | [ipfs-cluster/ipfs-cluster#339](https://github.com/ipfs-cluster/ipfs-cluster/issues/339) | [ipfs-cluster/ipfs-cluster#350](https://github.com/ipfs-cluster/ipfs-cluster/issues/350) - * Introduce `disable_repinning` option | [ipfs-cluster/ipfs-cluster#369](https://github.com/ipfs-cluster/ipfs-cluster/issues/369) | [ipfs-cluster/ipfs-cluster#387](https://github.com/ipfs-cluster/ipfs-cluster/issues/387) - * Documentation moved to website and fixes | [ipfs-cluster/ipfs-cluster#390](https://github.com/ipfs-cluster/ipfs-cluster/issues/390) | [ipfs-cluster/ipfs-cluster#391](https://github.com/ipfs-cluster/ipfs-cluster/issues/391) | [ipfs-cluster/ipfs-cluster#393](https://github.com/ipfs-cluster/ipfs-cluster/issues/393) | [ipfs-cluster/ipfs-cluster#347](https://github.com/ipfs-cluster/ipfs-cluster/issues/347) - * Run Docker container with `daemon --upgrade` by default | [ipfs-cluster/ipfs-cluster#394](https://github.com/ipfs-cluster/ipfs-cluster/issues/394) - * Remove the `ipfs-cluster-ctl peers add` command (bootstrap should be used to add peers) | [ipfs-cluster/ipfs-cluster#397](https://github.com/ipfs-cluster/ipfs-cluster/issues/397) - * Add tests using HTTPs endpoints | [ipfs-cluster/ipfs-cluster#191](https://github.com/ipfs-cluster/ipfs-cluster/issues/191) | [ipfs-cluster/ipfs-cluster#403](https://github.com/ipfs-cluster/ipfs-cluster/issues/403) - * Set `refs` as default `pinning_method` and `10` as default `concurrent_pins` | [ipfs-cluster/ipfs-cluster#420](https://github.com/ipfs-cluster/ipfs-cluster/issues/420) - * Use latest `gx` and `gx-go`.

An error will be displayed if `ipfs-cluster-service` is started with an old configuration file. We recommend re-initing the configuration file altogether. - -* The `peers` and `bootstrap` keys have been removed from the main section of the configuration -* You might need to provide Peer multiaddresses in a text file named `peerstore`, in your `~/.ipfs-cluster` folder (one per line). This allows your peers how to contact other peers. -* A `disable_repinning` option has been added to the main configuration section. Defaults to `false`. -* A `init_peerset` has been added to the `raft` configuration section. It should be used to define the starting set of peers when a cluster starts for the first time and is not bootstrapping to an existing running peer (otherwise it is ignored). The value is an array of peer IDs. -* A `backups_rotate` option has been added to the `raft` section and specifies how many copies of the Raft state to keep as backups when the state is cleaned up. -* An `ipfs_request_timeout` option has been introduced to the `ipfshttp` configuration section, and controls the timeout of general requests to the ipfs daemon. Defaults to 5 minutes. -* A `pin_timeout` option has been introduced to the `ipfshttp` section, it controls the timeout for Pin requests to ipfs. Defaults to 24 hours. -* An `unpin_timeout` option has been introduced to the `ipfshttp` section. it controls the timeout for Unpin requests to ipfs. Defaults to 3h. -* Both `pinning_timeout` and `unpinning_timeout` options have been removed from the `maptracker` section. -* A `monitor/pubsubmon` section configures the new PubSub monitoring component. The section is identical to the existing `monbasic`, its only option being `check_interval` (defaults to 15 seconds). - -The `ipfs-cluster-data` folder has been renamed to `raft`. Upon `ipfs-cluster-service daemon` start, the renaming will happen automatically if it exists. Otherwise it will be created with the new name. - -##### REST API - -There are no changes to REST APIs in this release. - -##### Go APIs - -Several component APIs have changed: `Consensus`, `PeerMonitor` and `IPFSConnector` have added new methods or changed methods signatures. - -##### Other - -Calling `ipfs-cluster-service` without subcommands no longer runs the peer. It is necessary to call `ipfs-cluster-service daemon`. Several daemon-specific flags have been made subcommand flags: `--bootstrap` and `--alloc`. - -The `--bootstrap` flag can now take a list of comma-separated multiaddresses. Using `--bootstrap` will automatically run `state clean`. - -The `ipfs-cluster-ctl` no longer has a `peers add` subcommand. Peers should not be added this way, but rather bootstrapped to an existing running peer. - ---- - -### v0.3.5 - 2018-03-29 - -This release comes full with new features. The biggest ones are the support for parallel pinning (using `refs -r` rather than `pin add` to pin things in IPFS), and the exposing of the http endpoints through libp2p. This allows users to securely interact with the HTTP API without having to setup SSL certificates. - -* Features - * `--no-status` for `ipfs-cluster-ctl pin add/rm` allows to speed up adding and removing by not fetching the status one second afterwards.

The `api/rest/client` provides a new `IPFS()` method. - -We recommend updating the `service.json` configurations to include all the new configuration options: - -* The `pin_method` option has been added to the `ipfshttp` section. It supports `refs` and `pin` (default) values. Use `refs` for parallel pinning, but only if you don't run automatic GC on your ipfs nodes. -* The `concurrent_pins` option has been added to the `maptracker` section. Only useful with `refs` option in `pin_method`. -* The `listen_multiaddress` option in the `restapi` section should be renamed to `http_listen_multiaddress`. - -This release will require a **state upgrade**. Run `ipfs-cluster-service state upgrade` in all your peers, or start cluster with `ipfs-cluster-service daemon --upgrade`. - ---- - -### v0.3.4 - 2018-02-20 - -This release fixes the pre-built binaries. - -* Bugfixes - * Pre-built binaries panic on start | [ipfs-cluster/ipfs-cluster#320](https://github.com/ipfs-cluster/ipfs-cluster/issues/320) - ---- - -### v0.3.3 - 2018-02-12 - -This release includes additional `ipfs-cluster-service state` subcommands and the connectivity graph feature. - -* Features - * `ipfs-cluster-service daemon --upgrade` allows to automatically run migrations before starting | [ipfs-cluster/ipfs-cluster#300](https://github.com/ipfs-cluster/ipfs-cluster/issues/300) | [ipfs-cluster/ipfs-cluster#307](https://github.com/ipfs-cluster/ipfs-cluster/issues/307) - * `ipfs-cluster-service state version` reports the shared state format version | [ipfs-cluster/ipfs-cluster#298](https://github.com/ipfs-cluster/ipfs-cluster/issues/298) | [ipfs-cluster/ipfs-cluster#307](https://github.com/ipfs-cluster/ipfs-cluster/issues/307) - * `ipfs-cluster-service health graph` generates a .dot graph file of cluster connectivity | [ipfs-cluster/ipfs-cluster#17](https://github.com/ipfs-cluster/ipfs-cluster/issues/17) | [ipfs-cluster/ipfs-cluster#291](https://github.com/ipfs-cluster/ipfs-cluster/issues/291) | [ipfs-cluster/ipfs-cluster#311](https://github.com/ipfs-cluster/ipfs-cluster/issues/311) - -* Bugfixes - * Do not upgrade state if already up to date | [ipfs-cluster/ipfs-cluster#296](https://github.com/ipfs-cluster/ipfs-cluster/issues/296) | [ipfs-cluster/ipfs-cluster#307](https://github.com/ipfs-cluster/ipfs-cluster/issues/307) - * Fix `ipfs-cluster-service daemon` failing with `unknown allocation strategy` error | [ipfs-cluster/ipfs-cluster#314](https://github.com/ipfs-cluster/ipfs-cluster/issues/314) | [ipfs-cluster/ipfs-cluster#315](https://github.com/ipfs-cluster/ipfs-cluster/issues/315) - -APIs have not changed in this release. The `/health/graph` endpoint has been added. - ---- - -### v0.3.2 - 2018-01-25 - -This release includes a number of bufixes regarding the upgrade and import of state, along with two important features: - * Commands to export and import the internal cluster state: these allow to perform easy and human-readable dumps of the shared cluster state while offline, and eventually restore it in a different peer or cluster. - * The introduction of `replication_factor_min` and `replication_factor_max` parameters for every Pin (along with the deprecation of `replication_factor`). The defaults are specified in the configuration. For more information on the usage and behavior of these new options, check the IPFS cluster guide. - -* Features - * New `ipfs-cluster-service state export/import/cleanup` commands | [ipfs-cluster/ipfs-cluster#240](https://github.com/ipfs-cluster/ipfs-cluster/issues/240) | [ipfs-cluster/ipfs-cluster#290](https://github.com/ipfs-cluster/ipfs-cluster/issues/290) - * New min/max replication factor control | [ipfs-cluster/ipfs-cluster#277](https://github.com/ipfs-cluster/ipfs-cluster/issues/277) | [ipfs-cluster/ipfs-cluster#292](https://github.com/ipfs-cluster/ipfs-cluster/issues/292) - * Improved migration code | [ipfs-cluster/ipfs-cluster#283](https://github.com/ipfs-cluster/ipfs-cluster/issues/283) - * `ipfs-cluster-service version` output simplified (see below) | [ipfs-cluster/ipfs-cluster#274](https://github.com/ipfs-cluster/ipfs-cluster/issues/274) - * Testing improvements: - * Added tests for Dockerfiles | [ipfs-cluster/ipfs-cluster#200](https://github.com/ipfs-cluster/ipfs-cluster/issues/200) | [ipfs-cluster/ipfs-cluster#282](https://github.com/ipfs-cluster/ipfs-cluster/issues/282) - * Enabled Jenkins testing and made it work | [ipfs-cluster/ipfs-cluster#256](https://github.com/ipfs-cluster/ipfs-cluster/issues/256) | [ipfs-cluster/ipfs-cluster#294](https://github.com/ipfs-cluster/ipfs-cluster/issues/294) - * Documentation improvements: - * Guide contains more details on state upgrade procedures | [ipfs-cluster/ipfs-cluster#270](https://github.com/ipfs-cluster/ipfs-cluster/issues/270) - * ipfs-cluster-ctl exit status are documented on the README | [ipfs-cluster/ipfs-cluster#178](https://github.com/ipfs-cluster/ipfs-cluster/issues/178) - -* Bugfixes - * Force cleanup after sharness tests | [ipfs-cluster/ipfs-cluster#181](https://github.com/ipfs-cluster/ipfs-cluster/issues/181) | [ipfs-cluster/ipfs-cluster#288](https://github.com/ipfs-cluster/ipfs-cluster/issues/288) - * Fix state version validation on start | [ipfs-cluster/ipfs-cluster#293](https://github.com/ipfs-cluster/ipfs-cluster/issues/293) - * Wait until last index is applied before attempting snapshot on shutdown | [ipfs-cluster/ipfs-cluster#275](https://github.com/ipfs-cluster/ipfs-cluster/issues/275) - * Snaps from master not pushed due to bad credentials - * Fix overpinning or underpinning of CIDs after re-join | [ipfs-cluster/ipfs-cluster#222](https://github.com/ipfs-cluster/ipfs-cluster/issues/222) - * Fix unmarshaling state on top of an existing one | [ipfs-cluster/ipfs-cluster#297](https://github.com/ipfs-cluster/ipfs-cluster/issues/297) - * Fix catching up on imported state | [ipfs-cluster/ipfs-cluster#297](https://github.com/ipfs-cluster/ipfs-cluster/issues/297) - -These release is compatible with previous versions of ipfs-cluster on the API level, with the exception of the `ipfs-cluster-service version` command, which returns `x.x.x-shortcommit` rather than `ipfs-cluster-service version 0.3.1`. The former output is still available as `ipfs-cluster-service --version`. - -The `replication_factor` option is deprecated, but still supported and will serve as a shortcut to set both `replication_factor_min` and `replication_factor_max` to the same value. This affects the configuration file, the REST API and the `ipfs-cluster-ctl pin add` command. - ---- - -### v0.3.1 - 2017-12-11 - -This release includes changes around the consensus state management, so that upgrades can be performed when the internal format changes.
