* rpc: improve codec abstraction
rpc.ServerCodec is an opaque interface. There was only one way to get a
codec using existing APIs: rpc.NewJSONCodec. This change exports
newCodec (as NewFuncCodec) and NewJSONCodec (as NewCodec). It also makes
all codec methods non-public to avoid showing internals in godoc.
While here, remove codec options in tests because they are not
supported anymore.
* p2p/simulations: use github.com/gorilla/websocket
This package was the last remaining user of golang.org/x/net/websocket.
Migrating to the new library wasn't straightforward because it is no
longer possible to treat WebSocket connections as a net.Conn.
* vendor: delete golang.org/x/net/websocket
* rpc: fix godoc comments and run gofmt
This removes the dashboard project. The dashboard was an experimental
browser UI for geth which displayed metrics and chain information in
real time. We are removing it because it has marginal utility and nobody
on the team can maintain it.
Removing the dashboard removes a lot of dependency code and shaves
6 MB off the geth binary size.
This adds an implementation of node discovery via DNS TXT records to the
go-ethereum library. The implementation doesn't match EIP-1459 exactly,
the main difference being that this implementation uses separate merkle
trees for tree links and ENRs. The EIP will be updated to match p2p/dnsdisc.
To maintain DNS trees, cmd/devp2p provides a frontend for the p2p/dnsdisc
library. The new 'dns' subcommands can be used to create, sign and deploy DNS
discovery trees.
* rpc: implement websockets with github.com/gorilla/websocket
This change makes package rpc use the github.com/gorilla/websocket
package for WebSockets instead of golang.org/x/net/websocket. The new
library is more robust and supports all WebSocket features including
continuation frames.
There are new tests for two issues with the previously-used library:
- TestWebsocketClientPing checks handling of Ping frames.
- TestWebsocketLargeCall checks whether the request size limit is
applied correctly.
* rpc: raise HTTP/WebSocket request size limit to 5MB
* rpc: remove default origin for client connections
The client used to put the local hostname into the Origin header because
the server wanted an origin to accept the connection, but that's silly:
Origin is for browsers/websites. The nobody would whitelist a particular
hostname.
Now that the server doesn't need Origin anymore, don't bother setting
one for clients. Users who need an origin can use DialWebsocket to
create a client with arbitrary origin if needed.
* vendor: put golang.org/x/net/websocket back
* rpc: don't set Origin header for empty (default) origin
* rpc: add HTTP status code to handshake error
This makes it easier to debug failing connections.
* ethstats: use github.com/gorilla/websocket
* rpc: fix lint
* vendor: remove unused dependencies
These were used by swarm code, which has now migrated to its own repository.
* travis.yml: remove sudo requirement for test builders
These needed sudo to run FUSE tests for swarm.
* accounts/scwallet: Add a switch to enable smartcard support
* accounts: change the meaning of the switch
* disable card support in windows until tested
* only activate account if pcscd socket file is present
* the switch is now the path to the socket file
* accounts/scwallet: holiman's review feedback
* accounts/scwallet: send the path to go-pcsclite
* accounts/scwallet: add default, per platform path
* accounts/scwallet: fix error log warning
* accounts/scwallet: update pcsc lib to latest
* accounts/scwallet: use default path from pcsclite
* scwallet: forgot to change switch name
* cmd: minor style cleanups (error handling first, then happy path)
* core, eth: some fixes for freezer
* vendor, core/rawdb, cmd/geth: add db inspector
* core, cmd/utils: check ancient store path forceily
* cmd/geth, common, core/rawdb: a few fixes
* cmd/geth: support windows file rename and fix rename error
* core: support ancient plugin
* core, cmd: streaming file copy
* cmd, consensus, core, tests: keep genesis in leveldb
* core: write txlookup during ancient init
* core: bump database version
* core, eth, trie: bloom filter for trie node dedup during fast sync
* eth/downloader, trie: address review comments
* core, ethdb, trie: restart fast-sync bloom construction now and again
* eth/downloader: initialize fast sync bloom on startup
* eth: reenable eth/62 until we properly remove it
