I think this should fix the issue. As solution we make every retry with a
temporary channel and copy results to the final channel which is only closed
by us. This only affects streaming methods.
This commit introduces an api.Cid type and replaces the usage of cid.Cid
everywhere.
The main motivation here is to override MarshalJSON so that Cids are
JSON-ified as '"Qm...."' instead of '{ "/": "Qm....." }', as this "ipld"
representation of IDs is horrible to work with, and our APIs are not issuing
IPLD objects to start with.
Unfortunately, there is no way to do this cleanly, and the best way is to just
switch everything to our own type.
This commit makes all the changes to make Peers() a streaming call.
While Peers is usually a non problematic call, for consistency, all calls
returning collections assembled through broadcast to cluster peers are now
streaming calls.
This commit continues the work of taking advantage of the streaming
capabilities in go-libp2p-gorpc by improving the ipfsconnector and pintracker
components.
StatusAll and RecoverAll methods are now streaming methods, with the REST API
output changing accordingly to produce a stream of GlobalPinInfos rather than
a json array.
pin/ls request to the ipfs daemon now use ?stream=true and avoid having to
load the full pinset map on memory. StatusAllLocal and RecoverAllLocal
requests to the pin tracker stream all the way and no longer store the full
pinset, and the full PinInfo status slice before sending it out.
We have additionally switched to a pattern where streaming methods receive the
channel as an argument, allowing the caller to decide on whether to launch a
goroutine, do buffering etc.
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.
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.
- Human-sizes for freespace metrics. Display whether if metric is
expires in something like "expires in 3m".
- When not passing metric name `ipfs-cluster-ctl health metrics` hits
the the metrics endpoint which returns a list of available metrics and
displays to user
- Humanize metrics output
- Sort metrics output
- cluster method, ipfs connector method, rpc and rest apis,
command, etc for repo gc
- Remove extra space from policy generator
- Added special timeout for `/repo/gc` call to IPFS
- Added `RepoGCLocal` cluster rpc method, which will be used to run gc
on local IPFS daemon
- Added peer name to the repo gc struct
- Sorted with peer ids, while formatting(only affects cli
results)
- Special timeout setting where timeout gets checked from last update
- Added `local` argument, which would run gc only on contacted peer
