0) Adjust BIP16 & BIP30 enforcement values
1) Reduce amount that peers can adjust our time to eliminate an attack vector. Thanks to
coblee for this fix.
2) Zeitgeist2 patch - thanks to Lolcust and ArtForz. This fixes an issue where a
51% attack can change difficulty at will. Go back the full period unless it's the
first retarget after genesis.
3) Avoid overflow in CalculateNextWorkRequired(). Thanks to pooler for the overflow fix.
4) SegWit ContextualCheckBlockHeader adjustment and extra coverage
5) Reject peer proto version below 70002. Thanks to wtogami for this patch.
6) Adjust default settings for Litecoin
* This removes block-size-limiting code in favor of GBT clients
doing the limiting themselves (if at all).
* -blockmaxsize is deprecated and only used to calculate an implied
blockmaxweight, addressing confusion from multiple users.
* getmininginfo's currentblocksize return value was returning
garbage values, and has been removed, also removing a
GetSerializeSize call in some block generation inner loops and
potentially addressing some performance edge cases.
Github-Pull: #11100

The first argument of estimatesmartfee was renamed from nblocks to
conf_target in 06bcdb8da6. Update the
client-side table as well.

Use POSIX rename atomicity at the `bitcoind` side to create a working
cookie atomically:
- Write `.cookie.tmp`, close file
- Rename `.cookie.tmp` to `.cookie`
This avoids clients reading invalid/partial cookies as in #11129.

The hex is already returned in TxToUniv, no need to give it out a
second independent time in getrawtransaction itself.

This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).
We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.
Raise RPC_WALLET_NOT_SPECIFIED instead of RPC_METHOD_NOT_FOUND when a required
wallet filename was not specified in an RPC call.
Also raise more specific RPC_WALLET_NOT_FOUND error instead of
RPC_INVALID_PARAMETER in case an invalid wallet was specified, for consistency.
Create a combinerawtransaction RPC which accepts a json array of hex raw
transactions to combine them into one transaction. Signrawtransaction is changed
to no longer combine transactions and only accept one transaction at a time.
Change parameter for conservative estimates to be an estimate_mode string.
Change to never return a -1 for failure but to instead omit the feerate and
return an error string. Throw JSONRPC error on invalid nblocks parameter.
This check has been moved to the wallet logic GetMinimumFee. The rpc call to
estimatesmartfee will now no longer return a result maxed with the mempool min
fee, but automated fee calculations from the wallet will produce the same result
as before and coincontrol and sendcoins dialogs in the GUI will correctly
display the right prospective fee.
changes to policy/fees.cpp include a big whitespace indentation change.
Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate
size limit from the weight limit when it fact it is superfluous,
and used in early tests before the witness data has been
validated or just to compute worst case sizes. The size checks
that use it would not behave any differently consensus wise
if they were eliminated completely.
Its correct value is not independently settable but is a function
of the weight limit and weight formula.
This patch just eliminates it and uses the scale factor as
required to compute the worse case constants.
It also moves the weight factor out of primitives into consensus,
which is a more logical place for it.
Add support for setting each of these attributes on a per RPC call basis to sendtoaddress, sendmany, fundrawtransaction (already had RBF), and bumpfee (already had RBF and conf target).
This makes it possible to mine to any wallet when multi-wallet mode is added.
Solves the same problem as #10649, but IMO in a cleaner way.
It also gets rid of the circuitous `ScriptForMining` method on
`CValidationInterface`, which really doesn't belong there.
After this change it's still possible to mine without wallet through
`generatetoaddress`.
A few "a->an" and "an->a".
"Shows, if the supplied default SOCKS5 proxy" -> "Shows if the supplied default SOCKS5 proxy". Change made on 3 occurrences.
"without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command".
Removed duplicate words such as "the the".
We currently do two resolves for dns seeds: one for the results, and one to
serve in addrman as the source for those addresses.
There's no requirement that the source hostname resolves to the stored
identifier, only that the mapping is unique. So rather than incurring the
second lookup, combine a private subnet with a hash of the hostname.
The resulting v6 ip is guaranteed not to be publicy routable, and has only a
negligible chance of colliding with a user's internal network (which would be
of no consequence anyway).
We can call gettxoutproof() with a list of transactions. Currently, if
the first transaction is unspent (and all other transactions are in the
same block), then the call will succeed. If the first transaction has
been spent, then the call will fail. The means that the following two
calls will return different results:
gettxoutproof(unspent_tx1, spent_tx1)
gettxoutproof(spent_tx1, unspent_tx1)
This commit makes behaviour independent of transaction ordering by looping
through all transactions provided and trying to find which block they're in.
This commit also increases the test coverage and tests more failure
cases for gettxoutproof()
CCoinsViewCache doesn't actually support cursor iteration returning the
current contents of the cache, so raise an error when the cursor method is
called instead of returning a cursor that iterates over stale data.
Also update the gettxoutsetinfo RPC which was relying on the old behavior to be
explicit about which view it is returning data about.
