* provider: protect libp2p connections
Use latest kad-dht version, introducing connection protection and
retention of addresses in peerstore during provide operations.
* depend on kad-dht master
* fix: SweepingProvider shouldn't error when missing DHT
* fix: prevent panic when SweepingProvider has no DHT
when SweepingProvider is enabled but no DHT is available (e.g., Routing.Type=none),
the daemon would panic with a nil pointer dereference in ResettableKeystore.ResetCids.
this fix:
- returns NoopProvider when no DHT implementation is available
- skips keystore initialization for NoopProvider to avoid unnecessary operations
- allows nodes to run without DHT when using HTTP-only routing or offline mode
the panic occurred because initKeyStore tried to access a nil keystore when
SweepingProvider returned nil for the keystore parameter. by checking if the
provider is NoopProvider and skipping keystore operations, we avoid the panic
while maintaining correct behavior for all other provider types.

* feat: allow custom http provide when offline
* refactor: improve offline HTTP provider handling and tests
- fixed comment/function name mismatch
- added mock server test for HTTP provide success
- clarified test names for offline scenarios
* test: simplify single-node provider tests
use h.NewNode().Init() instead of NewNodes(1) for cleaner test setup
* fix: allow SweepingProvider to work with HTTP-only routing
when no DHT is available but HTTP routers are configured for providing,
return NoopProvider instead of failing. this allows the daemon to start
and HTTP-based providing to work through the routing system.
moved HTTP provider detection to config package as HasHTTPProviderConfigured()
for better code organization and reusability.
this fix is important as SweepingProvider will become the new default in the future.

* Provide according to strategy
Updates boxo to a version with the changes from https://github.com/ipfs/boxo/pull/976, which decentralize the providing responsibilities (from a central providing.Exchange to blockstore, pinner, mfs).
The changes consist in initializing the Pinner, MFS and the blockstore with the provider.System, which is created first.
Since the provider.System is created first, the reproviding KeyChanFunc is set
later when we can create it once we have the Pinner, MFS and the blockstore.
Some additional work applies to the Add() workflow. Normally, blocks would get provided at the Blockstore or the Pinner, but when adding blocks AND a "pinned" strategy is used, the blockstore does not provide, and the
pinner does not traverse the DAG (and thus doesn't provide either), so we need to provide directly from the Adder. This is resolved by wrapping the DAGService in a "providingDAGService" which provides every added block, when using the "pinned" strategy.
`ipfs --offline add` when the ONLINE daemon is running will now announce blocks per the chosen strategy, where before it did not announce them. This is documented in the changelog. A couple of releases ago, adding with `ipfs --offline add` was faster, but this is no longer the case so we are not incurring in any penalties by sticking to the fact that the daemon is online and has a providing strategy that we follow.

* provider: clear reprovide queue when reprovide strategy changes
When the currently configured reprovide strategy does not match the previous strategy read from the datastore, then clear the reprovide queue and update the reprovide strategy that is stored in the datastore.

Fixes#10596.
The reproviding process can take long. Currently, each CID to be provided is
obtained by making a query to the pinner and reading one by one as the CIDs
get provided.
While this query is ongoing, the pinner holds a Read mutex on the pinset.
If a pin-add-request arrives, a goroutine will start waiting for a Write mutex
on the pinset. From that point, no new Read mutexes can be taken until the writer
can proceed and finishes.
However, no one can proceed because the read mutex is still held while the
reproviding is ongoing.
The fix is mostly in Boxo, where we add a "buffered" provider which reads the
cids onto memory so that they can be provided at its own pace without making
everyone wait.
The consequence is we will need more RAM memory. Rule of thumb is 1GiB extra per 20M cids to be reprovided.
New multi-router configuration system based on https://hackmd.io/G1KRDEX5T3qyfoBMkIrBew#Methods
- Added a new routing type: "custom"
- Added specific struct types for different Routers (instead of map[string]interface{})
- Added `Duration` config type, to make easier time string parsing
- Added config documentation.
- Use the latest go-delegated-routing library version with GET support.
- Added changelog notes for this feature.
It:
- closes#9157
- closes#9079
- closes#9186
* Delegated Routing.
Implementation of Reframe specs (https://github.com/ipfs/specs/blob/master/REFRAME.md) using go-delegated-routing library.
* Requested changes.
* Init using op string
* Separate possible ContentRouters for TopicDiscovery.
If we don't do this, we have a ciclic dependency creating TieredRouter.
Now we can create first all possible content routers, and after that,
create Routers.
* Set dht default routing type
* Add tests and remove uneeded code
* Add documentation.
* docs: Routing.Routers
* Requested changes.
Signed-off-by: Antonio Navarro Perez <antnavper@gmail.com>
* Add some documentation on new fx functions.
* Add changelog entry and integration tests
* test: sharness for 'dht' in 'routing' commands
Since 'routing' is currently the same as 'dht' (minus query command)
we need to test both, that way we won't have unnoticed divergence
in the default behavior.
* test(sharness): delegated routing via reframe URL
* Add more tests for delegated routing.
* If any put operation fails, the tiered router will fail.
* refactor: Routing.Routers: Parameters.Endpoint
As agreed in https://github.com/ipfs/kubo/pull/8997#issuecomment-1175684716
* Try to improve CHANGELOG entry.
* chore: update reframe spec link
* Update go-delegated-routing dependency
* Fix config error test
* use new changelog format
* Remove port conflict
* go mod tidy
* ProviderManyWrapper to ProviderMany
* Update docs/changelogs/v0.14.md

* feat: switch to using go-ipld-prime for codecs, path resolution, and the `dag put/get` commands
* fix: `dag put/get` not roundtripping due to an extra new line being added (https://github.com/ipfs/go-ipfs/issues/3503)
More detailed information is in the CHANGELOG.md file. Very high level:
* IPLD codecs (and their plugins) must use go-ipld-prime
* Added support for the dag-json codec
* `dag get/put` use IPLD codec names from the multicodec table
* `dag get` defaults to dag-json output instead of json, but may output with other codecs
* Data model pathing can be achieved using the /ipld prefix. For example, you can use `/ipld/QmFoo/Links/0/Hash` to traverse through a DagPB node
* With `dag get/put` the DagPB field names have been changed to match the ones in the protobuf listed in the specification
