We now consider debugerrors harmful: we've run into cases where
debugerror.Wrap() hid valuable error information (err == io.EOF?).
I've removed them from the main code, but left them in some tests.
Go errors are lacking, but unfortunately, this isn't the solution.
It is possible that debugerros.New or debugerrors.Errorf should
remain still (i.e. only remove debugerrors.Wrap) but we don't use
these errors often enough to keep.
⚠️ this commit makes your current configs unusable, as the
default bootstrap peers. You may need to edit your config.
Go from:
```js
Bootstrap: [
{
"Address": "/ip4/104.131.131.82/tcp/4001",
"PeerID": "QmaCpDMGvV2BGHeYERUEnRQAwe3N8SzbUtfsmvsqQLuvuJ"
}
]
```
To:
```js
Bootstrap: [
"/ip4/104.131.131.82/tcp/4001/ipfs/QmaCpDMGvV2BGHeYERUEnRQAwe3N8SzbUtfsmvsqQLuvuJ"
]
```
The pkg.Interface style is modeled after heap.Interface. Generally, I
find it helpful for interfaces that have many implementations. It
provides clear distinction between the generic interface and the |n|
implementations that implement it (which may be interface types
themselves).
For clients who cannot keep the repo name, one can imagine that the most
likely rename is `ipfsrepo`. In that case, `ipfsrepo.Interface` remains
meaningful.
This is low-pri so it doesn't matter than much. But for the record, the
repo.Interface feels appropriate in this use-case.
this commit:
* moves parsing of bootstrap peers into config
* moves location of bootstrap addrs into core/commands
* refactor `*BootstrapPeer -> BootstrapPeer
