This adds a Timestamp field to the pin objects. This allows to track when they were pinned.
This:
* Allows the pin-tracker to actually show accurate information on when the pin
entered the system for pins that are not part of ongoing operations
(currently it shows time.Now())
* Adds support for reporting timestamp on a pinning services api.
This is a follow up to #1360 which further optimizes StatusAll calls by
avoiding listing and filtering the cluster state when requesting status for
operations that should be direclty in the operation tracker because they are
ongoing (queued, pinning, unpinning, error).
This commit modifies the pintracker StatusAll call to take a status filter.
This allows to skip a PinLs call to ipfs when checking status for items that
are queued, pinning, unpinning or in error. Those status come directly from
the operation tracker. This should result in a significant performance
increase for those calls, particularly in nodes with several hundred thousand
pins and more, where the call to IPFS is very expensive.
A new TrackerStatusUnexpectedlyUnpinned status has been introduce to
differentiate between pin errors (tracked by the operation tracker) and "lost"
items (which before were pin errors too). This new status is handled by the
Recover() operation as before.
GlobalPinInfo objects carried redundant information (Cid, Peer) that takes
space and time to serialize.
This has been addressed by having GlobalPinInfo embed PinInfoShort rather than
PinInfo. This new types ommits redundant fields.
Receive the full pin object so that it can decide whether to check
for recursive or direct pins directly.
Additionally, unpin will not check for the pin presence anymore and
simply trigger unpins (ignoring errors)
* Libp2p protectors no longer needed, use PSK directly
* Generate cluster 32-byte secret here (helper gone from pnet)
* Switch to go-log/v2 in all places
* DHT bootstrapping not needed. Adjust DHT options for tests.
* Do not rely on dissappeared CidToDsKey and DsKeyToCid functions fro dshelp.
* Disable QUIC (does not support private networks)
* Fix tests: autodiscovery started working properly
StateSync() used to take care of this by issuing Track() calls. But this
functionality was removed.
This starts returning items that are in the state but not on IPFS as
PIN_ERRORs. It ensures that the Recover methods see them so that they can
trigger repinnings for missing items. This covers cases where the user
modifies the ipfs state manually, or resets the ipfs daemon but keeps the
cluster state, and cases where cluster was stopped half-way through a pinning.
This removes mappintracker and sets stateless tracker as the default (and only) pintracker component.
Because the stateless tracker matches the cluster state with only ongoing operations being kept on memory, and additional information provided by ipfs-pin-ls, syncing operations are not necessary. Therefore the Sync/SyncAll operations are removed cluster-wide.
- abort if a Track() calls fails due to queue being full
- increase max pin queue size to 1 million
- hind max_pin_queue_size from configuration
- use an elaborated error message
Fixes#377
I had thought of this for a very long time but there were no compelling
reasons to do it. Specifying RPC endpoint permissions becomes however
significantly nicer if each Component is a different RPC Service. This also
fixes some naming issues like having to prefix methods with the component name
to separate them from methods named in the same way in some other component
(Pin and IPFSPin).
This adds a new "crdt" consensus component using go-ds-crdt.
This implies several refactors to fully make cluster consensus-component
independent:
* Delete mapstate and fully adopt dsstate (after people have migrated).
* Return errors from state methods rather than ignoring them.
* Add a new "datastore" modules so that we can configure datastores in the
main configuration like other components.
* Let the consensus components fully define the "state.State". Thus, they do
not receive the state, they receive the storage where we put the state (a
go-datastore).
* Allow to customize how the monitor component obtains Peers() (the current
peerset), including avoiding using the current peerset. At the moment the
crdt consensus uses the monitoring component to define the current peerset.
Therefore the monitor component cannot rely on the consensus component to
produce a peerset.
* Re-factor/re-implementation of "ipfs-cluster-service state"
operations. Includes the dissapearance of the "migrate" one.
The CRDT consensus component defines creates a crdt-datastore (with ipfs-lite)
and uses it to intitialize a dssate. Thus the crdt-store is elegantly
wrapped. Any modifications to the state get automatically replicated to other
peers. We store all the CRDT DAG blocks in the local datastore.
The consensus components only expose a ReadOnly state, as any modifications to
the shared state should happen through them.
DHT and PubSub facilities must now be created outside of Cluster and passed in
so they can be re-used by different components.
This takes advantange of the latest features in go-cid, peer.ID and
go-multiaddr and makes the Go types serializable by default.
This means we no longer need to copy between Pin <-> PinSerial, or ID <->
IDSerial etc. We can now efficiently binary-encode these types using short
field keys and without parsing/stringifying (in many cases it just a cast).
We still get the same json output as before (with minor modifications for
Cids).
This should greatly improve Cluster performance and memory usage when dealing
with large collections of items.

This commit adds support for OpenCensus tracing
and metrics collection. This required support for
context.Context propogation throughout the cluster
codebase, and in particular, the ipfscluster component
interfaces.
The tracing propogates across RPC and HTTP boundaries.
The current default tracing backend is Jaeger.
The metrics currently exports the metrics exposed by
the opencensus http plugin as well as the pprof metrics
to a prometheus endpoint for scraping.
The current default metrics backend is Prometheus.
Metrics are currently exposed by default due to low
overhead, can be turned off if desired, whereas tracing
is off by default as it has a much higher performance
overhead, though the extent of the performance hit can be
adjusted with smaller sampling rates.
