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 fixes the issue about partitions not being picked based
on the amount of freespace available in them.
It additionally removes the metrics registry and carries information directly
in the metric.
Metrics have two additional fields: Weight and Partitionable.
Informers have been updated to make use of these fields. Partitions have
weights that equals to the weight of the metrics under them.
Older cluster versions will not set these fields. Partitionable is false by
default and weight has a GetWeight() function to convert value->weight when
unset. This provides backwards compatibility for the freespace metric.
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.
The new "metrics" allocator is about to partition metrics and distribe
allocations among the partitions.
For example: given a region, an availability zone and free space on disk, the
allocator would be able to choose allocations by distributing among regions
and availability zones as much as possible, and for those peers in the same
region/az, selecting those with most free space first.
This requires a major overhaul of the allocator component.
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.
The errors returned by the IPFS Proxy API are not understood by IPFS.
This was caused by go-ipfs-cmds setting an API error format which requires the
errors to have a type: "error" field.
This commit brings this up to speed.
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.
The Allocations of a pin that has been added with default replication factor
are kept even when the replication factor turns out to be -1.
This resulted in the Status(cid) code skipping calls to a number of peers
and setting the pin directly as REMOTE.
The fix, on one side makes sure Allocations is always nil when the replication
factor is -1. On the other size, lets the globalPinInfoCid method check the
replication factor value, rather than the number of allocations to decide if
any nodes are bound to be remote.
On the plus side, the pin tracker used the IsRemotePin method, which uses the
replication factor, so things were pinned even if the Status(cid) method shows
them as remote.
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
Fixes#1286. Some AddedOutput objects carry an undefined CID. This was getting
stringified as 'b', making the proxy responses include this rather than
skipping setting the field.
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.
This adds a new pin option: Mode that can be set to "direct" or "recursive".
The Mode is used to set the MaxDepth Pin field accordingly. When set to 0, we
will call pin/add using the type=direct.
* 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
Currently we were only specifying the block format. When adding with
a custom hash function, even though we produced the right cids, IPFS
did not know the hash function and ended up storing them using SHA256.
Additionally, since NodeWithMeta serializes the CID, we do not need
to carry a Format parameter (which specifies the Codec): it is already
embedded.
Tests have been added and BlockPut in ipfshttp now checks that the
response's CID matches the data sent. This will catch errors like
what was happening, but also any data corruption between cluster and
IPFS during the block upload.
* add ipv6 listening addresses to the default config
* ipfsproxy: support multiple listeners. Add default ipv6.
* mm

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
* pin() should not allocate if allocations are already provided
* pin() should not skip pinning if the exact same pin exists
* Additionally this was unreliable as it allocated it before
so the pin may have existed but the allocations may have been
artificially changed.
* pin() re-uses existing pin when pin options are the same and thus
avoids changing the allocations of a pin.
As a side effect, this fixes re-allocations which were broken: peers
called `shouldPeerRepinCid()` and instead of repinning that single
cid proceeded to repin the full state. For every pin.
Additionally tests have been adapted. It may be that some re-alloc tests
were very unreliable for the problems above.
This commit introduces `--local` option for `ctl add` which would add
content only the local ipfs peer and then pin it according to pin
options (fetching from the local peer)
For achieving this, a new local dag service is introduced
- Instead of using a boolean config element(send logs to std out or
file), use a string element that would store path of the log file.
That way user has freedom to choose the filepath. Use std out if this
path is empty.
This commit introduces logging for Cluster HTTP APIs.
It adds a config element `send_logs_to_file`, which tells whether logs
should be saved in a file or shown in standard output.
Requests are logged as per Apache Common Log Format (CLF)
