This commit introduces the new go-libp2p-gorpc streaming capabilities for
Cluster. The main aim is to work towards heavily reducing memory usage when
working with very large pinsets.
As a side-effect, it takes the chance to revampt all types for all public
methods so that pointers to static what should be static objects are not used
anymore. This should heavily reduce heap allocations and GC activity.
The main change is that state.List now returns a channel from which to read
the pins, rather than pins being all loaded into a huge slice.
Things reading pins have been all updated to iterate on the channel rather
than on the slice. The full pinset is no longer fully loaded onto memory for
things that run regularly like StateSync().
Additionally, the /allocations endpoint of the rest API no longer returns an
array of pins, but rather streams json-encoded pin objects directly. This
change has extended to the restapi client (which puts pins into a channel as
they arrive) and to ipfs-cluster-ctl.
There are still pending improvements like StatusAll() calls which should also
stream responses, and specially BlockPut calls which should stream blocks
directly into IPFS on a single call.
These are coming up in future commits.
This does 3 things:
- Add a NoPin option to the adder. When set to true, the adding process does not
send a pin in the end.
- When user-allocations are set and local=true happens, we do not overwrite
the allocations returned by the allocator to include the local peer
anymore, as this could alter user-allocations.
- Some code improvement (remove pointers).
This allows to specifically request status for several CIDs as
provided in the "cids" query parameter, instead of request status for
all CIDs.
In this case, the filter is ignored.
This is a preparatory PR to add additional APIs (Pinning Service API) easily
to cluster.
Instead of copy-pasting most of what the REST API does, I have refactored so
that the whole configuration, routing and request-handling utilities can be
re-used.
The worst part has been to divide the test between tests that test core
(common.API) functionality and tests that test specific REST API endpoint
functionality. I could not get away without an additional common/test package
to provide functions that are used from both places. This is a side effect of
testing both http and libp2p endpoints for every request etc.
This commit updates the WaitFor StatusFilterParams to add a Limit field, and
reworks the waiting logic to simplify it.
The Limit parameter causes WaitFor to return successfully when N number of
peers have reached the target status, regardless of what other statuses are
(as long as they are not errors)
Other than that, the function logic should remain the same, blocking until all
statuses are the target, with a special case about target-Pinned, which causes
Remote statuses to be ignored.
The Gorilla muxer StrictSlash option uses a 301 permanent redirect, which
results in POST requests becoming GET requests in most clients. Thus we use
our own middleware that performs a 307 redirect. See issue #1415 for more
details.
The restapi component supports filters for the pinset. This was done to keep
expected output when sharding was fully supported by filtering out "internal"
pins.
However this filter requires looping on the full pinset and re-allocating and
usually does nothing. The useless copy is significant for really big pinsets.
Additionally, ipfs-cluster-ctl set the filter by default to "pins". By setting
it to "all" instead we can skip the whole filtering step and, in practice, get the
same results.
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.
This commit adds a new add option: "format".
This option specifies how IPFS Cluster is expected to build the DAG when
adding content. By default, it takes a "unixfs", which chunks and DAG-ifies as
it did before, resulting in a UnixFSv1 DAG.
Alternatively, it can be set to "car". In this case, Cluster will directly
read blocks from the CAR file and add them.
Adding CAR files or doing normal processing is independent from letting
cluster do sharding or not. If sharding is ever enabled, Cluster could
potentially shard a large CAR file among peers.
Currently, importing CAR files is limited to a single CAR file with a single
root (the one that is pinned). Future iterations may support multiple CARs
and/or multiple roots by transparently wrapping them.
Instead they should use noise, and fallback to tls.
This should not break compatibility with previous versions as both old and new
are able to speak tls.
Fixes#1315
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.
* 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
* add ipv6 listening addresses to the default config
* ipfsproxy: support multiple listeners. Add default ipv6.
* mm
* restapi: support multiple listen addresses. enable ipv6
* cluster_config: format default listen addresses
* commands: update for multiple listeners. Fix randomports for udp and ipv6.
* ipfs-cluster-service: fix randomports test
* multiple listeners: fix remaining tests
* golint
* Disable ipv6 in defaults
It is not supported by docker by default. It is not supported in travis-CI
build environments. User can enable it now manually.
* proxy: disable ipv6 in test
* ipfshttp: fix test

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.
This adds a new PinOption: ExpireAt.
The StateSync ticker will check and unpin expired pins from the Cluster.
ipfs-cluster-ctl supports an "expire-in" which gives a duration.
