This fixes cross-build and mobile framework failures.
It also disables the mac test builder because it was failing
all the time in hard to understand ways and we can't afford
it anymore under Travis CI's new pricing.
This new flag downloads a known version of Go and builds with it. This
is meant for environments where we can't easily upgrade the installed Go
version.
* .travis.yml: remove install step for PR test builders
We added this step originally to avoid re-building everything
for every test. go test has become much smarter in recent go
releases, so we no longer need to install anything here.
- Remove the ws:// prefix from the status endpoint since
the ws:// is already included in the stack.WSEndpoint().
- Don't register the services again in the node start.
Registration is already done in the initialization stage.
- Expose admin namespace via websocket.
This namespace is necessary for connecting the peers via websocket.
- Offer logging relevant options for exec adapter.
It's really painful to mix all log output in the single console. So
this PR offers two additional options for exec adapter in this case
testers can config the log output(e.g. file output) and log level
for each p2p node.

This PR contains a minor optimization in derivesha, by exposing the RLP
int-encoding and making use of it to write integers directly to a
buffer (an RLP integer is known to never require more than 9 bytes
total). rlp.AppendUint64 might be useful in other places too.
The code assumes, just as before, that the hasher (a trie) will copy the
key internally, which it does when doing keybytesToHex(key).

This PR replaces the old test genesis.json and chain.rlp files in the testdata
directory for the eth protocol test suite, and also adds documentation for
running the eth test suite locally.
It also improves the test output text and adds more timeouts.

TAP is a text format for test results. Parsers for it are available in many languages,
making it easy to consume. I want TAP output from our protocol tests because the
Hive wrapper around them needs to know about the test names and their individual
results and logs. It would also be possible to just write this info as JSON, but I don't
want to invent a new format.
This also improves the normal console output for tests (when running without --tap).
It now prints -- RUN lines before any output from the test, and indents the log output
by one space.
* core/state/snapshot: print warning if failed to resolve journal
* core/state/snapshot: fix snapshot recovery
When we meet the snapshot journal consisted with:
- disk layer generator with new-format
- diff layer journal with old-format
The base layer should be returned without error.
The broken diff layer can be reconstructed later
but we definitely don't want to reconstruct the
huge diff layer.
* core: add tests
ToHex was deprecated a couple years ago. The last remaining use
was in ToHexArray, which itself only had a single call site.
This just moves ToHexArray near its only remaining call site and
implements it using hexutil.Encode. This changes the default behaviour
of ToHexArray and with it the behaviour of eth_getProof. Previously we
encoded an empty slice as 0, now the empty slice is encoded as 0x.
This adds a few tiny fixes for les and the p2p simulation framework:
LES Parts
- Keep the LES-SERVER connection even it's non-synced
We had this idea to reject the connections in LES protocol if the les-server itself is
not synced. However, in LES protocol we will also receive the connection from another
les-server. In this case even the local node is not synced yet, we should keep the tcp
connection for other protocols(e.g. eth protocol).
- Don't count "invalid message" for non-existing GetBlockHeadersMsg request
In the eth syncing mechanism (full sync, fast sync, light sync), it will try to fetch
some non-existent blocks or headers(to ensure we indeed download all the missing chain).
In this case, it's possible that the les-server will receive the request for
non-existent headers. So don't count it as the "invalid message" for scheduling
dropping.
- Copy the announce object in the closure
Before the les-server pushes the latest headers to all connected clients, it will create
a closure and queue it in the underlying request scheduler. In some scenarios it's
problematic. E.g, in private networks, the block can be mined very fast. So before the
first closure is executed, we may already update the latest_announce object. So actually
the "announce" object we want to send is replaced.
The downsize is the client will receive two announces with the same td and then drop the
server.
P2P Simulation Framework
- Don't double register the protocol services in p2p-simulation "Start".
The protocols upon the devp2p are registered in the "New node stage". So don't reigster
them again when starting a node in the p2p simulation framework
- Add one more new config field "ExternalSigner", in order to use clef service in the
framework.

The old one was wrong in two ways: the first block in chain.rlp was the
genesis block, and the genesis difficulty was below minimum difficulty.
This also contains some other fixes to the test.
* accounts/keystore: add timeout to test to prevent failure on travis
The TestWalletNotifications test sporadically fails on travis.
This is because we shutdown the event collection before all events are received.
Adding a small timeout (10 milliseconds) allows the collector to be scheduled
and to consume all pending events before we shut it down.
* accounts/keystore: added newlines back in
* accounts/keystore: properly fix the walletNotifications test
* miner: exit loop when downloader Done or Failed
Following the logic of the comment at the method,
this fixes a regression introduced at 7cf56d6f06
, which would allow external parties to DoS with
blocks, preventing mining progress.

* miner: add test describing expectations for downloader/mining events
We expect that once the downloader emits a DoneEvent,
signaling a successful sync, that subsequent StartEvents
are not longer permitted to stop the miner.
This prevents a security vulnerability where forced syncs via
fake high blocks would stall mining operation.

* miner: use 'canStop' state to fix downloader event handling
- Break downloader event handling into event
separating Done and Failed events. We need to
treat these cases differently since a DoneEvent
should prevent the miner from being stopped on
subsequent downloader Start events.
- Use canStop state to handle the one-off
case when a downloader first succeeds.

The go routine handling the downloader events handling
