This PR adds support for using Twitter API to query the tweet and author details. There are two reasons behind this change:
- Twitter will be deprecating the legacy website on 15th December. The current method is expected to stop working then.
- More importantly, the current system uses Twitter handle for spam protection but the Twitter handle can be changed via automated calls. This allows bots to use the same tweet to withdraw funds infinite times as long as they keep changing their handle between every request. The Rinkeby as well as the Goerli faucet are being actively drained via this method. This PR changes the spam protection to be based on Twitter IDs instead of usernames. A user can not change their Twitter ID.
In miner/worker.go, there are two goroutine using channel w.newWorkCh: newWorkerLoop() sends to this channel, and mainLoop() receives from this channel. Only the receive operation is in a select.
However, w.exitCh may be closed by another goroutine. This is fine for the receive since receive is in select, but if the send operation is blocking, then it will block forever. This commit puts the send in a select, so it won't block even if w.exitCh is closed.
Similarly, there are two goroutines using channel errc: the parent that runs the test receives from it, and the child created at line 573 sends to it. If the parent goroutine exits too early by calling t.Fatalf() at line 614, then the child goroutine will be blocked at line 574 forever. This commit adds 1 buffer to errc. Now send will not block, and receive is not influenced because receive still needs to wait for the send.
The previous fix#21960 converted the float to an intermediate signed int, before attempting the uint conversion. Although this works, this doesn't guarantee that other architectures will work the same.
This commit fixes a flaw in two testcases, and brings down the exec-time from ~40s to ~8s for trie/TestIncompleteSync.
The checkConsistency was performed over and over again on the complete set of nodes, not just the recently added, turning it into a quadratic runtime.
The database panicked for invalid IPs. This is usually no problem
because all code paths leading to node DB access verify the IP, but it's
dangerous because improper validation can turn this panic into a DoS
vulnerability. The quick fix here is to just turn database accesses
using invalid IP into a noop. This isn't great, but I'm planning to
remove the node DB for discv5 long-term, so it should be fine to have
this quick fix for half a year.
Fixes#21849
This fixes some issues in crypto/signify and makes release signing work.
The archive signing step in ci.go used getenvBase64, which decodes the key data.
This is incorrect here because crypto/signify already base64-decodes the key.
* core: add test for headerchain inserts
* core, light: write headerchains in batches
* core: change to one callback per batch of inserted headers + review concerns
* core: error-check on batch write
* core: unexport writeHeaders
* core: remove callback parameter in InsertHeaderChain
The semantics of InsertHeaderChain are now much simpler: it is now an
all-or-nothing operation. The new WriteStatus return value allows
callers to check for the canonicality of the insertion. This change
simplifies use of HeaderChain in package les, where the callback was
previously used to post chain events.
* core: skip some hashing when writing headers
* core: less hashing in header validation
* core: fix headerchain flaw regarding blacklisted hashes

Both Hash and Address have a String method, which returns the value as
hex with 0x prefix. They also had a Format method which tried to print
the value using printf of []byte. The way Format worked was at odds with
String though, leading to a situation where fmt.Sprintf("%v", hash)
returned the decimal notation and hash.String() returned a hex string.
This commit makes it consistent again. Both types now support the %v,
%s, %q format verbs for 0x-prefixed hex output. %x, %X creates
unprefixed hex output. %d is also supported and returns the decimal
notation "[1 2 3...]".
For Address, the case of hex characters in %v, %s, %q output is
determined using the EIP-55 checksum. Using %x, %X with Address
disables checksumming.

This commit enables users to specify which signer they want to use while creating their transactOpts.
Previously all contract interactions used the homestead signer. Now a user can specify whether they
want to sign with homestead or EIP155 and specify the chainID which adds another layer of security.

A lot of times when we hit 'core' errors, example: invalid tx, the information provided is
insufficient. We miss several pieces of information: what account has nonce too high,
and what transaction in that block was offending?
This PR adds that information, using the new type of wrapped errors.
It also adds a testcase which (partly) verifies the output from the errors.
The first commit changes all usage of direct equality-checks on core errors, into
using errors.Is. The second commit adds contextual information. This wraps most
of the core errors with more information, and also wraps it one more time in
stateprocessor, to further provide tx index and tx hash, if such a tx is encoutered in
a block. The third commit uses the chainmaker to try to generate chains with such
errors in them, thus triggering the errors and checking that the generated string meets
expectations.
This PR fixes a deadlock reported here: #21925
The cause is that many operations may be pending, but if the close happens, only one of them gets awoken and exits, the others remain waiting for a signal that never comes.
* signer/core/api: fix derivation of ledger live accounts
For ledger hardware wallets, change account iteration as follows:
- ledger legacy: m/44'/60'/0'/X; for 0<=X<5
- ledger live: m/44'/60'/0'/0/X; for 0<=X<5
- ledger legacy: m/44'/60'/0'/X; for 0<=X<10
- ledger live: m/44'/60'/X'/0/0; for 0<=X<10
Non-ledger derivation is unchanged and remains as:
- non-ledger: m/44'/60'/0'/0/X; for 0<=X<10
* signer/core/api: derive ten default paths for all hardware wallets, plus ten legacy and ten live paths for ledger wallets
* signer/core/api: as .../0'/0/0 already included by default paths, do not include it again with ledger live paths
* accounts, signer: implement path iterators for hd wallets
