leveldb's buildsystem causes us a few problems:
- breaks out-of-tree builds
- forces flags used for some tools
- limits cross builds
Rather than continuing to add wrappers around it, simply integrate it into our
build.

Remove the mistaken assumption that GetKey returning false signifies
an internal database issue. It will return false when the key cannot
be deserialized into the (char,uint256) stanza, which indicates
that the cursor has reached a different kind of key.
Fixes bug #7890 introduced in #7756.
Without the newline I see "bein" where the two lines are concatenated:
Note that all inputs selected must be of standard form and P2SH scripts must *bein* the wallet using importaddress or addmultisigaddress (to calculate fees).
swap was using an incorrect condition to determine when to apply an optimization
(not swapping the full direct[] when swapping two indirect prevectors).
Rather than correct the optimization I'm removing it for simplicity. Removing
this optimization minutely improves performance in the typical (currently only)
usage of member swap(), which is swapping with a freshly value-initialized
object.
Fixes a bug in which pop_back did not call the deleted item's destructor.
Using the most general erase() implementation to implement all the others
prevents similar bugs because the coupling between deallocation and destructor
invocation only needs to be maintained in one place.
Also reduces duplication of complex memmove logic.
The key (transaction id for the following outputs) should be serialized
to the HashWriter.
This is a problem as it means different transactions in the same
position with the same outputs will potentially result in the same hash.
Fixes primary concern of #7758.
Break the circular dependency between main and txdb by:
- Moving `CBlockFileInfo` from `main.h` to `chain.h`. I think this makes
sense, as the other block-file stuff is there too.
- Moving `CDiskTxPos` from `main.h` to `txdb.h`. This type seems
specific to txdb.
- Pass a functor `insertBlockIndex` to `LoadBlockIndexGuts`. This leaves
it up to the caller how to insert block indices.
Byte counts for SHA256, SHA512, SHA1 and RIPEMD160 must be 64 bits.
`size_t` has a different size per platform, causing divergent results
when hashing more than 4GB of data.
Add a method Cursor() to CCoinsView that returns a cursor which can be
used to iterate over the whole UTXO set.
- rpc: Change gettxoutsetinfo to use new Cursor method
- txdb: Remove GetStats method - Now that GetStats is implemented in
terms of Cursor, remove it.

85c807c getblockchaininfo: make bip9_softforks an object, not an array. (Rusty Russell)
We can't change "softforks", but it seems far more logical to use tags
in an object rather than using an "id" field in an array.
For example, to get the csv status before, you need to iterate the
array to find the entry with 'id' field equal to "csv":
jq '.bip9_softforks | map(select(.id == "csv"))[] | .status'
Now:
jq '.bip9_softforks.csv.status'
There is no issue with fork names being incompatible with JSON tags,
since we're selecting them ourselves.

Previously we used the CInv that would be sent to the peer announcing the
transaction as the key, but using the txid instead allows us to decouple the
p2p layer from the application logic (which relies on this map to avoid
duplicate tx requests).
The lockorder potential deadlock detection works by remembering for each
lock A that is acquired while holding another B the pair (A,B), and
triggering a warning when (B,A) already exists in the table.
A and B in the above text are represented by pointers to the CCriticalSection
object that is acquired. This does mean however that we need to clean up the
table entries that refer to any critical section which is destroyed, as it
memory address can potentially be used for another unrelated lock in the future.
Implement this clean up by remembering not only the pairs in forward direction,
but also backward direction. This allows for fast iteration over all pairs that
use a deleted CCriticalSection in either the first or the second position.
The current tests for varint only check that
serialization-deserialization is a roundtrip. That is a useful test, but
it is also good to check for some exact bit patterns, to prevent a code
change that changes the serialization format from going undetected.
As the varint functions are templated, also check with different types.

Currently, we're keeping a timeout for each requested block, starting
from when it is requested, with a correction factor for the number of
blocks in the queue.
That's unnecessarily complicated and inaccurate.
As peers process block requests in order, we can make the timeout for each
block start counting only when all previous ones have been received, and
have a correction based on the number of peers, rather than the total number
of blocks.
Two-line patch to make it possible to shut down bitcoind cleanly during
the initial ActivateBestChain.
Fixes#6459 (among other complaints).
To reproduce:
- shutdown bitcoind
- copy chainstate
- start bitcoind
- let the chain sync a bit
- shutdown bitcoind
- copy back old chainstate
- start bitcoind
- bitcoind will catch up with all blocks during Init()
(the `boost::this_thread::interruption_point` / `ShutdownRequested()`
dance is ugly, this should be refactored all over bitcoind at some point
when moving from boost::threads to c++11 threads, but it works...)
They claimed to be testing P2SH scripts with non-push scriptSigs, but
1) they were not enabling P2SH
2) they have push-only scriptSigs
Fix this, and add a few more related cases.
Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
Ubuntu 16.04 "xenial xerus" does not come with Python 2.x by default.
It is possible to install a python-2.7 package, but this has its own
problem: no `python` or `python2` symlink (see #7717).
This fixes the following scripts to work with python 3:
- `make check` (bctest,py, bitcoin-util-test.py)
- `make translate` (extract_strings_qt.py)
- `make symbols-check` (symbol-check.py)
- `make security-check` (security-check.py)
Explicitly call the python commands using $(PYTHON) instead
of relying on the interpreter line at the top of the scripts.
The build date does only makes sense for custom/self-compiled bitcoin-core versions because we are using static build-dates for our deterministic release builds.
Having a quick option to get the current datadir is much more valuable for debug purposes.
The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.
Creates the generatetoaddress rpc which is virtually identical to the generate rpc except that it takes an argument for the address to mine to. It does not rely on wallet functionality.
The mining code shared by generate and generatetoaddress has been moved to another method to reduce duplication.

This implements caching of ancestor state to each mempool entry, similar to
descendant tracking, but also including caching sigops-with-ancestors (as that
metric will be helpful to future code that implements better transaction
selection in CreatenewBlock).
The work limit served to prevent the descendant walking algorithm from doing
too much work by marking the parent transaction as dirty. However to implement
ancestor tracking, it's not possible to similarly mark those descendant
transactions as dirty without having to calculate them to begin with.
This commit removes the work limit altogether. With appropriate
chain limits (-limitdescendantcount) the concern about doing too much
work inside this function should be mitigated.
While trying to find a black/white version of the Bitcoin
logo for the organization I noticed the about.png is not
entirely black - it has some reflection. Remove this to make
it the same as other icons.
Also ran the icons through `contrib/devtools/optimize-pngs.py`,
so `chevron.png` was optimized too.

It looks like, TorController::disconnected_cb(TorControlConnection&
conn) gets called multiple times which results in multiple event_new().
Avoid this by creating the event only once in the constructore, and
deleting it only once in the destructor (thanks to Cory Fields for the
idea).
Replaces the fix by Jonas Schnelli in #7610, see discussion there.
Continues "Make logging for validation optional" from #6519.
The idea there was to remove all ERROR logging of rejected transaction,
and move it to one message in the class 'mempoolrej' which logs the
state message (and debug info). The superfluous ERRORs in the log
"terrify" users, see for example issue #5794.
Unfortunately a lot of new logging was introduced in #6871 (RBF) and
#7287 (misc refactoring). This pull updates that new code.
f22f14c doc: mention bitcoin-cli -stdin in release notes (Wladimir J. van der Laan)
92bcca3 rpc: Input-from-stdin mode for bitcoin-cli (Wladimir J. van der Laan)
Implements #7442 by adding an option `-stdin` which reads
additional arguments from stdin, one per line.
For example
```bash
echo -e "mysecretcode\n120" | src/bitcoin-cli -stdin walletpassphrase
echo -e "walletpassphrase\nmysecretcode\n120" | src/bitcoin-cli -stdin
```
BerkeleyDB dump files have key and value lines indented.
The salvage code passes these to ParseHex as-is.
Check this in the tests (should just pass with current code).
Check for EOF before every getline, and warn when reading gets to EOF
before the end of the data.
Stricter error checking could shed more light on issues such as #7463
and #7379.
- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112)
<nSequence> CHECKSEQUENCEVERIFY -> <nSequence>
- Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block.
- Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence()
- Add bitwise AND operator to CScriptNum
- Enable CHECKSEQUENCEVERIFY as a standard script verify flag
- Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.
Check the returned script_error. Add expected script_error
for generated as well as custom tests.
The specific error is not part of consensus, however
it could avoid unclear reporting issues such as #6862 in the future.
Fixes#7513.
SequenceLocks functions are used to evaluate sequence lock times or heights per BIP 68.

If number of conflict confirms cannot be determined, this means
that the block is still unknown or not yet part of the main chain,
for example during a reindex. Do nothing in that case,
instead of crash with an assertion.
Fixes#7234.
This test is no longer relevant.
It was introduced in 8c222dca4f to check
the switch to 1MB blocks after the BDB too-many-locks issue back in
2013. The switching code has been long since removed.
It also needs a specific data file that is hard to find. I've verified
in #6320 that it still passes, however I think there is zero reason to
keep it.
Closes#6320.

ProcessNewBlock would return failure early if CheckBlock failed, before
calling AcceptBlock. AcceptBlock also calls CheckBlock, and upon failure
would update mapBlockIndex to indicate that a block was failed. By returning
early in ProcessNewBlock, we were not marking blocks that fail a check in
CheckBlock as permanently failed, and thus would continue to re-request and
reprocess them.
This corrects a bug the case of tying group size where the code may
fail to select the group with the newest member. Since newest time
is the final selection criteria, failing to break ties on it
on the step before can undermine the final selection.
Tied netgroups are very common.

With automatic tor HS support in place we should probably not be providing

(cherry picked from commit 46dbcd4833115401fecbb052365b4c7725874414)
Previously didn't make clear that the ContextualCheckBlock* functions
meant the block headers as context - not the UTXO set itself - and that
ConnectBlock() also did UTXO-related validity checks (in the future we
may split that functionality into a separate UTXO-specific contextual
check block function).
Also, reordered to put validity checks first for better readability.
Also renames whitelistalwaysrelay.
Nodes relay all transactions from whitelisted peers, this
gets in the way of some useful reasons for whitelisting
peers-- for example, bypassing bandwidth limitations.
The purpose of this forced relaying is for specialized gateway
applications where a node is being used as a P2P connection
filter and multiplexer, but where you don't want it getting
in the way of (re-)broadcast.
This change makes it configurable with whitelistforcerelay.

Unconfirmed transactions that are not in your mempool either due to eviction or other means may be unlikely to be mined. abandontransaction gives the wallet a way to no longer consider as spent the coins that are inputs to such a transaction. All dependent transactions in the wallet will also be marked as abandoned.
Due to include ordering, defining in one place was not enough to ensure correct
usage. Use global defines so that we don't have to worry abou this ordering.
Also add a comment in configure about the test.

noexcept is default for destructors as of c++11. By throwing in reverselock's
destructor if it's lock has been tampered with, the likely result is
std::terminate being called. Indeed that happened before this change.
Once reverselock has taken another lock (its ctor didn't throw), it makes no
sense to try to grab or lock the parent lock. That is be broken/undefined
behavior depending on the parent lock's implementation, but it shouldn't cause
the reverselock to fail to re-lock when destroyed.
To avoid those problems, simply swap the parent lock's contents with a dummy
for the duration of the lock. That will ensure that any undefined behavior is
caught at the call-site rather than the reverse lock's destruction.
Barring a failed mutex unlock which would be indicative of a larger problem,
the destructor should now never throw.
This is ugly, but temporary. boost::filesystem will likely be dropped soon
after c++11 is enabled. Otherwise, we could simply roll our own copy_file. I've
fixed this at the buildsystem level for now in order to avoid mixing in
functional changes.
Explanation:
If boost (prior to 1.57) was built without c++11, it emulated scoped enums
using c++98 constructs. Unfortunately, this implementation detail leaked into
the abi. This was fixed in 1.57.
When building against that installed version using c++11, the headers pick up
on the native c++11 scoped enum support and enable it, however it will fail to
link. This can be worked around by disabling c++11 scoped enums if linking will
fail.
Add an autoconf test to determine incompatibility. At build-time, if native
enums are being used (a c++11 build), and force-disabling them causes a
successful link, we can be sure that there's an incompatibility and enable the
work-around.
Don't scan the wallet to see if the current key has been used if we're going to make a new key anyway.
Stop scanning the wallet as soon as we see that the current key has been used.
Don't call isValid() twice on the current key.
After discussion in #7164 I think this is better.
Max tip age was introduced in #5987 to make it possible to run
testnet-in-a-box. But associating this behavior with the testnet chain
is wrong conceptually, as it is not needed in normal usage.
Should aim to make testnet test the software as-is.
Replace it with a (debug) option `-maxtipage`, which can be
specified only in the specific case.

We used to have a trickle node, a node which was chosen in each iteration of
the send loop that was privileged and allowed to send out queued up non-time
critical messages. Since the removal of the fixed sleeps in the network code,
this resulted in fast and attackable treatment of such broadcasts.
This pull request changes the 3 remaining trickle use cases by random delays:
* Local address broadcast (while also removing the the wiping of the seen filter)
* Address relay
* Inv relay (for transactions; blocks are always relayed immediately)
The code is based on older commits by Patrick Strateman.
- Avoids string typos (by making the compiler check)
- Makes it easier to grep for handling/generation of a certain message type
- Refer directly to documentation by following the symbol in IDE
- Move list of valid message types to protocol.cpp:
protocol.cpp is a more appropriate place for this, and having
the array there makes it easier to keep things consistent.

Some extra bytes in libconsensus to get all the crypto (except for signing, which is in the common module) below the libconsensus future independent repo (that has libsecp256k1 as a subtree).
hmac_sha256.o seems to be the only thing libbitcoinconsensus doesn't depend on from crypto, some more bytes for the final libconsensus: I'm not personally worried.
A further pass over the available inputs has been added to ApproximateBestSubset after a candidate set has been found. It will prune any extraneous inputs in the selected subset, in order to decrease the number of input and the resulting change.
Mempool requests use a fair amount of bandwidth when the mempool is large,
disconnecting peers using them follows the same logic as disconnecting
peers fetching historical blocks.

One test in AcceptToMemoryPool was to compare a transaction's fee
agains the value returned by GetMinRelayFee. This value was zero for
all small transactions. For larger transactions (between
DEFAULT_BLOCK_PRIORITY_SIZE and MAX_STANDARD_TX_SIZE), this function
was preventing low fee transactions from ever being accepted.
With this function removed, we will now allow transactions in that range
with fees (including modifications via PrioritiseTransaction) below
the minRelayTxFee, provided that they have sufficient priority.
Redo the feerate index to be based on mining score, rather than fee.
Update mempool_packages.py to test prioritisetransaction's effect on
package scores.
- Add new translations (finally, after a long time)
- update-translation script was not considering new translations - oops
- fixed this, also remove (nearly) empty translations
- Update translation process, it was still describing the old repository
structure
Use the score index on the mempool to only add sorted txs in order. Remove much of the validation while building the block, relying on mempool to be consistent and only contain txs that can be mined.
The mempool is assumed to be consistent as far as not containing txs which spend non-existent outputs or double spends, and scripts are valid. Finality of txs is still checked (except not coinbase maturity, assumed in mempool).
Still TestBlockValidity in case mempool consistency breaks and return error state if an invalid block was created.
Unit tests are modified to realize that invalid blocks can now be constructed if the mempool breaks its consistency assumptions and also updated to have the right fees, since the cached value is now used for block construction.
Conflicts:
src/miner.cpp
The score index is meant to represent the order of priority for being included in a block for miners. Initially this is set to the transactions modified (by any feeDelta) fee rate. Index improvements and unit tests by sdaftuar.
Store sum of legacy and P2SH sig op counts. This is calculated in AcceptToMemory pool and storing it saves redoing the expensive calculation in block template creation.
But keep translating them in the GUI.
This - necessarily - requires duplication of a few messages.
Alternative take on #7134, that keeps the translations from being wiped.
Also document GetWarnings() input argument.

Mruset setInventoryKnown was reduced to a remarkably small 1000
entries as a side effect of sendbuffer size reductions in 2012.
This removes setInventoryKnown filtering from merkleBlock responses
because false positives there are especially unattractive and
also because I'm not sure if there aren't race conditions around
the relay pool that would cause some transactions there to
be suppressed. (Also, ProcessGetData was accessing
setInventoryKnown without taking the required lock.)
This replaces using inv messages to announce new blocks, when a peer requests
(via the new "sendheaders" message) that blocks be announced with headers
instead of inv's.
Since headers-first was introduced, peers send getheaders messages in response
to an inv, which requires generating a block locator that is large compared to
the size of the header being requested, and requires an extra round-trip before
a reorg can be relayed. Save time by tracking headers that a peer is likely to
know about, and send a headers chain that would connect to a peer's known
headers, unless the chain would be too big, in which case we revert to sending
an inv instead.
Based off of @sipa's commit to announce all blocks in a reorg via inv,
which has been squashed into this commit.

This allows for much finer control of the transaction fees per kilobyte
as it prevent small transactions using a fee that is more appropriate
for one that is of a kilobyte.
This also allows controlling the fee per kilobyte over rpc such that:
bitcoin-cli settxfee `bitcoin-cli estimatefee 2`
would make sense, while currently it grossly fails often by a factor of x3
For each 'bit' in the filter we really maintain 2 bits, which store either:
0: not set
1-3: set in generation N
After (nElements / 2) insertions, we switch to a new generation, and wipe
entries which already had the new generation number, effectively switching
from the last 1.5 * nElements set to the last 1.0 * nElements set.
This is 25% more space efficient than the previous implementation, and can
(at peak) store 1.5 times the requested amount of history (though only
1.0 times the requested history is guaranteed).
The existing unit tests should be sufficient.
This switches the Merkle tree logic for blocks to one that runs in constant (small) space.
The old code is moved to tests, and a new test is added that for various combinations of
block sizes, transaction positions to compute a branch for, and mutations:
* Verifies that the old code and new code agree for the Merkle root.
* Verifies that the old code and new code agree for the Merkle branch.
* Verifies that the computed Merkle branch is valid.
* Verifies that mutations don't change the Merkle root.
* Verifies that mutations are correctly detected.

This makes sure that retransmits by a whitelisted peer also actually
result in a retransmit.
Further, this changes the logic to never relay in case we would assign
a DoS score, as we expect to get DoS banned ourselves as a result.
Adds 127.0.0.1:9050 for the .onion proxy if we can succesfully connect
to the control port.
Natural followup to creating hidden services automatically.
Previously all of these functions could return negative values (for different
readons). Large portions of the codebase currently assume that these
functions return positive values.
Previously peers which implement a protocol version less than NO_BLOOM_VERSION
would not be disconnected for sending a filter command, regardless of the
peerbloomfilter option.
Many node operators do not wish to provide expensive bloom filtering for SPV
clients, previously they had to cherry pick the commit which enabled the
disconnect logic.
The default should remain false until a sufficient percent of SPV clients
have updated.
1) Chainparams: Explicit CChainParams arg for main:
-AcceptBlock
-AcceptBlockHeader
-ActivateBestChain
-ConnectTip

-LoadExternalBlockFile
-VerifyDB parametric constructor
2) Also pickup more Params()\. in main.cpp
3) Pass nPruneAfterHeight explicitly to new FindFilesToPrune() in main.cpp
The setAskFor duplicate elimination was too eager and removed entries
when we still had no getdata response, allowing the peer to keep
INVing and not responding.
mapAlreadyAskedFor does not keep track of which peer has a request queued for a
particular tx. As a result, a peer can blind a node to a tx indefinitely by
sending many invs for the same tx, and then never replying to getdatas for it.
Each inv received will be placed 2 minutes farther back in mapAlreadyAskedFor,
so a short message containing 10 invs would render that tx unavailable for 20
minutes.
This is fixed by disallowing a peer from having more than one entry for a
particular inv in mapAlreadyAskedFor at a time.

Previously in blocks only mode all inv messages where type!=MSG_BLOCK would be
rejected without regard for whitelisting or whitelistalwaysrelay.
As such whitelisted peers would never send the transaction (which would be
processed).
Compute the value of inputs that already are in the chain at time of mempool entry and only increase priority due to aging for those inputs. This effectively changes the CTxMemPoolEntry's GetPriority calculation from an upper bound to a lower bound.
It's possible coins with the same hash exist when you create a duplicate coinbase, so previously we were reading from the database to make sure we had the old coins cached so if we were to spend the new ones, the old ones would also be spent. This pull instead just marks the new coins as not fresh if they are from a coinbase, so if they are spent they will be written all the way down to the database anyway overwriting any duplicates.
Previously it would break if you flushed a parent cache while there was a child cache referring to it. This change will allow the flushing of parent caches.

This provides more conservative estimates and reacts more quickly to a backlog.
Unfortunately the unit test for fee estimation depends on the success threshold (and the decay) chosen; also modify the unit test for the new default success thresholds.
These are more useful fee and priority estimation functions. If there is no fee/pri high enough for the target you are aiming for, it will give you the estimate for the lowest target that you can reliably obtain. This is better than defaulting to the minimum. It will also pass back the target for which it returned an answer.

Useful now that BIP113 is enforced for transactions entering the
mempool. Was previously only (indirectly) available by calling
getblocktemplate, a relatively expensive RPC call.
This continues/fixes #6719.
`event_base_loopbreak` was not doing what I expected it to, at least in
libevent 2.0.21.
What I expected was that it sets a timeout, given that no other pending
events it would exit in N seconds. However, what it does was delay the
event loop exit with 10 seconds, even if nothing is pending.
Solve it in a different way: give the event loop thread time to exit
out of itself, and if it doesn't, send loopbreak.
This speeds up the RPC tests a lot, each exit incurred a 10 second
overhead, with this change there should be no shutdown overhead in the
common case and up to two seconds if the event loop is blocking.
As a bonus this breaks dependency on boost::thread_group, as the HTTP
server minds its own offspring.

Previous text could be interpreted as the the _additional_ fee paid by
the result on top of the fee the original version paid, rather than the
correct interpretation: the absolute fee the resulting tx pays.
Previously all conflicting transactions were evaluated as a whole to
determine if the feerate was being increased. This meant that low
feerate children pulled the feerate down, potentially allowing a high
transaction with a high feerate to be replaced by one with a lower
feerate.
Replaces transactions already in the mempool if a new transaction seen
with a higher fee, specifically both a higher fee per KB and a higher
absolute fee. Children are evaluateed for replacement as well, using the
mempool package tracking to calculate replaced fees/size. Transactions
can opt-out of transaction replacement by setting nSequence >= maxint-1
on all inputs. (which all wallets do already)
Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket
API, to create and destroy 'ephemeral' hidden services programmatically.
https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service
This means that if Tor is running (and proper authorization is available),
bitcoin automatically creates a hidden service to listen on, without user
manual configuration. This will positively affect the number of available
.onion nodes.
- When the node is started, connect to Tor through control socket
- Send `ADD_ONION` command
- First time:
- Make it create a hidden service key
- Save the key in the data directory for later usage
- Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on).
- Keep control socket connection open for as long node is running. The hidden service will
(by default) automatically go away when the connection is closed.
Process `getheaders` messages from whitelisted peers even if we are in
initial block download. Whitelisted peers can always use a node as a
block source.
Also log a debug message when the request is ignored, for
troubleshooting.
Fixes#6971.

Previously, the undo weren't being flushed during a reindex because
fKnown was set to true in FindBlockPos. That is the correct behaviour
for block files as they aren't being touched, but undo files are
touched.
This changes the behaviour to always flush when switching to a new file
(even for block files, though that isn't really necessary).
The docs talk about bits 2 and 4 instead of 2 and 3, and bits are being
indexed from both 1 (describing nCode) and 0 (in second example).
Changed to use zero-indexing for all.

Revert "Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations""
This reverts commit 40cd32e835.
After careful analysis it was determined that the change was, in fact, safe and several people were suffering
momentary confusion about locktime semantics.
When processing a new transaction, in addition to spending the Coins of its txin's it creates a new Coins for its outputs. The existing ModifyCoins function will first make sure this Coins does not already exist. It can not exist due to BIP 30, but because of that the lookup can't be cached and always has to go to the database. Since we are creating the coins to match the new tx anyway, there is no point in checking if they exist first anyway. However this should not be used for coinbase tx's in order to preserve the historical behavior of overwriting the two existing duplicate tx pairs.
40cd32e Revert "Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations" (Gregory Maxwell)
8537ecd Revert "Enable policy enforcing GetMedianTimePast as the end point of lock-time constraints" (Gregory Maxwell)
This reverts commit 9d55050773.
As noted by Luke-Jr, under some conditions this will accept transactions which are invalid by the network
rules. This happens when the current block time is head of the median time past and a transaction's
locktime is in the middle.
This could be addressed by changing the rule to MAX(this_block_time, MTP+offset) but this solution and
the particular offset used deserve some consideration.
* Introduce new constant MIN_CHANGE and use it instead of the
hardcoded "CENT"
* Add test case for MIN_CHANGE
* Introduce new constant for -mintxfee default:
DEFAULT_TRANSACTION_MINFEE = 1000
Reduce the default limits on maximum number of transactions and the cumulative size of those transactions in both ancestor and descendant packages to 25 txs and 101kb total size.
Update the unittest that is meant to catch a transaction that is invalid
because it has a null input. The old test failed not because of that
but because it was considered a coinbase with too large script. This is
already checked with a different test, though.
The new test is *not* a coinbase since it has two inputs, but one of
them is null. This really checks the corresponding code path in
CheckTransaction.

dea8d21 Enable policy enforcing GetMedianTimePast as the end point of lock-time constraints (Mark Friedenbach)
9d55050 Add rules--presently disabled--for using GetMedianTimePast as endpoint for lock-time calculations (Mark Friedenbach)
Until now there were quite a few leftovers, and only the coverage
related files in `src/` were cleaned, while the ones in the other dirs
remained. `qa/tmp/` is related to the BitcoinJ tests, and `cache/` is
related to RPC tests.
Transactions are not allowed in the memory pool or selected for inclusion in a block until their lock times exceed chainActive.Tip()->GetMedianTimePast(). However blocks including transactions which are only mature under the old rules are still accepted; this is *not* the soft-fork required to actually rely on the new constraint in production.
The lock-time code currently uses CBlock::nTime as the cutoff point for time based locked transactions. This has the unfortunate outcome of creating a perverse incentive for miners to lie about the time of a block in order to collect more fees by including transactions that by wall clock determination have not yet matured. By using CBlockIndex::GetMedianTimePast from the prior block instead, the self-interested miner no longer gains from generating blocks with fraudulent timestamps. Users can compensate for this change by simply adding an hour (3600 seconds) to their time-based lock times.
If enforced, this would be a soft-fork change. This commit only adds the functionality on an unexecuted code path, without changing the behaviour of Bitcoin Core.
Nagle appears to be a significant contributor to latency now that the static
sleeps are gone. Most of our messages are relatively large compared to
IP + TCP so I do not expect this to create enormous overhead.
This may also reduce traffic burstyness somewhat.
Add a comment that explains why the initial "getheader" requests are
made starting from the block preceding the currently best one.
Thanks to sdaftuar for the explanation!
There is no exact science to setting this parameter, but 5000
(just over 1 US cent at the time of writing) is higher than the
cost to relay a transaction around the network (the new benchmark
due to mempool limiting).
After each transaction which is added to mempool, we first call
Expire() to remove old transactions, then throwing away the
lowest-feerate transactions.
After throwing away transactions by feerate, we set the minimum
relay fee to the maximum fee transaction-and-dependant-set we
removed, plus the default minimum relay fee.
After the next block is received, the minimum relay fee is allowed
to decrease exponentially. Its halflife defaults to 12 hours, but
is decreased to 6 hours if the mempool is smaller than half its
maximum size, and 3 hours if the mempool is smaller than a quarter
its maximum size.
The minimum -maxmempool size is 40*-limitdescendantsize, as it is
easy for an attacker to play games with the cheapest
-limitdescendantsize transactions. -maxmempool defaults to 300MB.
This disables high-priority transaction relay when the min relay
fee adjustment is >0 (ie when the mempool is full). When the relay
fee adjustment drops below the default minimum relay fee / 2 it is
set to 0 (re-enabling priority-based free relay).
(note the 9x multiplier on (void*)'s for CTxMemPool::DynamicMemoryUsage
was accidentally introduced in 5add7a7 but should have waited for this
commit which adds the extra index)
To bridge the time until a dynamic method for determining this fee is
merged.
This is especially aimed at the stable releases (0.10, 0.11) because
full mempool limiting, as will be in 0.12, is too invasive and risky to
backport.
1534d9a Creates unittests for addrman, makes addrman testable. Adds several unittests for addrman to verify it works as expected. Makes small modifications to addrman to allow deterministic and targeted tests. (EthanHeilman)
Adds an `obfuscate` parameter to `CLevelDBWrapper` and makes use of it
for all new chainstate stores built via `CCoinsViewDB`. Also adds an
`Xor` method to `CDataStream`.

This adds SCRIPT_VERIFY_LOW_S to STANDARD_SCRIPT_VERIFY_FLAGS which
will make the node require the canonical 'low-s' encoding for
ECDSA signatures when relaying or mining.
Consensus behavior is unchanged.
The rational is explained in a81cd96805:
Absent this kind of test ECDSA is not a strong signature as given
a valid signature {r, s} both that value and {r, -s mod n} are valid.
These two encodings have different hashes allowing third parties a
vector to change users txids. These attacks are avoided by picking
a particular form as canonical and rejecting the other form(s); in
the of the LOW_S rule, the smaller of the two possible S values is
used.
If widely deployed this change would eliminate the last remaining
known vector for nuisance malleability on boring SIGHASH_ALL
p2pkh transactions. On the down-side it will block most
transactions made by sufficiently out of date software.
Unlike the other avenues to change txids on boring transactions this
one was randomly violated by all deployed bitcoin software prior to
its discovery. So, while other malleability vectors where made
non-standard as soon as they were discovered, this one has remained
permitted. Even BIP62 did not propose applying this rule to
old version transactions, but conforming implementations have become
much more common since BIP62 was initially written.
Bitcoin Core has produced compatible signatures since a28fb70e in
September 2013, but this didn't make it into a release until 0.9
in March 2014; Bitcoinj has done so for a similar span of time.
Bitcoinjs and electrum have been more recently updated.
This does not replace the need for BIP62 or similar, as miners can
still cooperate to break transactions. Nor does it replace the
need for wallet software to handle malleability sanely[1]. This
only eliminates the cheap and irritating DOS attack.

- to match the peers.dat handling also supply a debug.log entry for how
many entries were loaded from banlist.dat and how long it took
- add a GUI init message for loading the banlist (same as with peers.dat)
- move the same message for peers.dat upwards in the code, to be able to
reuse the timing variable nStart and also just log, if our read from
peers.dat didn't fail
- only start working on/with banlist data, if reading in the banlist from
disk didn't fail
- as CNode::setBannedIsDirty is false (default) when reading fails, we
don't need to explicitly set it to false to prevent writing
banlist.dat in that case either
Previously only one PUSHDATA was allowed, needlessly limiting
applications such as matching OP_RETURN contents with bloom filters that
operate on a per-PUSHDATA level. Now any combination that passes
IsPushOnly() is allowed, so long as the total size of the scriptPubKey
is less than 42 bytes. (unchanged modulo non-minimal PUSHDATA encodings)
Also, this fixes the odd bug where previously the PUSHDATA could be
replaced by any single opcode, even sigops consuming opcodes such as
CHECKMULTISIG. (20 sigops!)
Previously unlike other transaction types the TX_SCRIPTHASH would not
clear vSolutionsRet, which means that unlike other transaction types if
it was called twice in a row you would get the result of the previous
invocation as well.
Avoid calling gettimeofday every time through the benchmarking loop, by keeping
track of how long each loop takes and doubling the number of iterations done
between time checks when they take less than 1/16'th of the total elapsed time.
Benchmarking framework, loosely based on google's micro-benchmarking
library (https://github.com/google/benchmark)
Wny not use the Google Benchmark framework? Because adding Even More Dependencies
isn't worth it. If we get a dozen or three benchmarks and need nanosecond-accurate
timings of threaded code then switching to the full-blown Google Benchmark library
should be considered.
The benchmark framework is hard-coded to run each benchmark for one wall-clock second,
and then spits out .csv-format timing information to stdout. It is left as an
exercise for later (or maybe never) to add command-line arguments to specify which
benchmark(s) to run, how long to run them for, how to format results, etc etc etc.
Again, see the Google Benchmark framework for where that might end up.
See src/bench/MilliSleep.cpp for a sanity-test benchmark that just benchmarks
'sleep 100 milliseconds.'
To compile and run benchmarks:
cd src; make bench
Sample output:
Benchmark,count,min,max,average
Sleep100ms,10,0.101854,0.105059,0.103881
This makes sure that the event loop eventually terminates, even if an
event (like an open timeout, or a hanging connection) happens to be
holding it up.
Add a WaitExit() call to http's WorkQueue to make it delete the work
queue only when all worker threads stopped.
This fixes a problem that was reproducable by pressing Ctrl-C during
AppInit2:
```
/usr/include/boost/thread/pthread/condition_variable_fwd.hpp:81: boost::condition_variable::~condition_variable(): Assertion `!ret' failed.
/usr/include/boost/thread/pthread/mutex.hpp:108: boost::mutex::~mutex(): Assertion `!posix::pthread_mutex_destroy(&m)' failed.
```
I was assuming that `threadGroup->join_all();` would always have been
called when entering the Shutdown(). However this is not the case in
bitcoind's AppInit2-non-zero-exit case "was left out intentionally
here".
Shutting down the HTTP server currently breaks off all current requests.
This can create a race condition with RPC `stop` command, where the calling
process never receives confirmation.
This change removes the listening sockets on shutdown so that no new
requests can come in, but no longer breaks off requests in progress.
Meant to fix#6717.
The "please check your computer's data and time" message when the clock
deviates from the network currently generates an overkill of messages:
orion@lethe:~/bitcoin$ src/bitcoind
Warning: Warning: Please check that your computer's date and time are correct! If your clock is wrong Bitcoin Core will not work properly.
In the log:

CalculateMemPoolAncestors was always looping over a transaction's inputs
to find in-mempool parents. When adding a new transaction, this is the
correct behavior, but when removing a transaction, we want to use the
ancestor set that would be calculated by walking mapLinks (which should
in general be the same set, except during a reorg when the mempool is
in an inconsistent state, and the mapLinks-based calculation would be the
correct one).
* Raise the debug window when hidden behind other windows
* Switch to the debug window when on another virtual desktop
* Show the debug window when minimized
This change is a conceptual copy of 5ffaaba and 382e9e2
Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.
To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.

The two timeouts for the server and client, are essentially different:
- In the case of the server it should be a lower value to avoid clients
clogging up connection slots
- In the case of the client it should be a high value to accomedate slow
responses from the server, for example for slow queries or when the
lock is contended
Split the options into `-rpcservertimeout` and `-rpcclienttimeout` with
respective defaults of 30 and 900.
Associate with each CTxMemPoolEntry all the size/fees of descendant
mempool transactions. Sort mempool by max(feerate of entry, feerate
of descendants). Update statistics on-the-fly as transactions enter
or leave the mempool.
Also add ancestor and descendant limiting, so that transactions can
be rejected if the number or size of unconfirmed ancestors exceeds
a target, or if adding a transaction would cause some other mempool
entry to have too many (or too large) a set of unconfirmed in-
mempool descendants.
Ignore SIGPIPE on all non-win32 OSes, otherwise an unexpectedly disconnecting
RPC client will terminate the application. This problem was introduced
with the libhttp-based RPC server.
Fixes#6660.

GetTransaction needs to lock cs_main until ReadBlockFromDisk completes, the data inside CBlockIndex's can change since pruning. This lock was held by all calls to GetTransaction except rest_tx.
- removes mapBlockIndex find operation
- theoretically allows removing the cs_main lock during zqm notification while introducing a new file position lock
- add missing NULL pointer checks
- add better comments and reorder some code in rpcconsole.cpp
- remove unneeded leftovers in bantable.cpp
- update bantable column sizes to prevent cutting of banned until
- remove banListChanged signal from client model
- directly call clientModel->getBanTableModel()->refresh() without the way
over clientModel->updateBanlist()
- also fix clearing peer detail window, when selecting (clicking)
peers in the ban list

We log the cleanSubVer as part of connect. It is not uniquely more informative
than any of the other data we have about a peer, often less. It's also often
long now as well. There is no need to output it as part of mempoolrej,
AcceptToMemoryPool, or pong entries. Leaving it out makes our log entries
more uniform and consistent.
This patch changes the way the suffix (giving the requested data format) is
parsed for REST requests. Before, the string was split at '.'
characters and it was assumed that the second part was the suffix.
Now, we look for the last dot and use that to determine the suffix.
This allows for strings that contain dots (not used now, though), and
seems, in general, to be clearer and more intuitive.
Complete rescan is incompatible with pruning, but rescan is optional on
our wallet key import RPCs. Import on use is very useful in some common
situations in conjunction with pruning, e.g. merchant payment tracking.
This reenables importprivkey/importaddress/importpubkey when rescan
is not used.
In the future we should consider changing the rescan argument to allow depth
or date to allow limited rescanning when compatible with the retained
block depth.
Lets nodes advertise that they offer bloom filter support explicitly.
The protocol version bump allows SPV nodes to assume that NODE_BLOOM is
set if NODE_NETWORK is set for pre-70011 nodes.
Also adds an option to turn bloom filter support off for nodes which
advertise a version number >= 70011. Nodes attempting to use bloom
filters on such protocol versions are banned, and a later upgade
should drop nodes of an older version which attempt to use bloom
filters.
Much code stolen from Peter Todd.

`nMinPingUsecTime` was left uninitialized in CNode.
The correct initialization for a minimum-until-now is int64_t's max value, so initialize it to that.

The main effect is to exit processing for recently-rejected hashes,
in case they are pushed to us without prior advertisement. This
behavior was seen in the wild.
An additional effect is to do early checks for mempool or mapOrphan
existence. No logging or nDoS tracking is needed for failures of
these checks.

Implement RPCTimerHandler for Qt RPC console, so that `walletpassphrase`
works with GUI and `-server=0`.
Also simplify HTTPEvent-related code by using boost::function directly.
- *Replace usage of boost::asio with [libevent2](http://libevent.org/)*.
boost::asio is not part of C++11, so unlike other boost there is no
forwards-compatibility reason to stick with it. Together with #4738 (convert
json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with
regard to compile-time slowness.
- *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling
is handled by libevent, a work queue (with configurable depth and parallelism)
is used to handle application requests.
- *Wrap HTTP request in C++ class*; this makes the application code mostly
HTTP-server-neutral
- *Refactor RPC to move all http-specific code to a separate file*.
Theoreticaly this can allow building without HTTP server but with another RPC
backend, e.g. Qt's debug console (currently not implemented) or future RPC
mechanisms people may want to use.
- *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL
paths they want to handle.
By using a proven, high-performance asynchronous networking library (also used
by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided.
What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests
pass. The aim for now is everything but SSL support.
Configuration options:
- `-rpcthreads`: repurposed as "number of work handler threads". Still
defaults to 4.
- `-rpcworkqueue`: maximum depth of work queue. When this is reached, new
requests will return a 500 Internal Error.
- `-rpctimeout`: inactivity time, in seconds, after which to disconnect a
client.
- `-debug=http`: low-level http activity logging
When running the rpc tests in Wine, nodes often fail to listen on localhost
due to a stale socket from a previous run. This aligns the behavior with other
platforms.
Fix https://github.com/bitcoin/bitcoin/issues/6558. In particular, stop
parsing JSON after the first object or array is finished. Check that no
other garbage follows, and fail the parser if it does.

functions (setgenerate and generate) crash with an assertion failure
(due to a NULL pointer script returned) if the keypool is empty. Fix
this by giving a proper error.

Add error checking to CLevelDBWrapper for errors from
leveldb::DestroyDB(). Without it, if unlink() or DeleteFileW() fail to
delete files, they will fail silent. If they fail to delete any files,
CLevelDBWrapper will silently open and read the existing database.
Typically any permissions issues would be caught by leveldb as it churns
through many files as part of its compaction process, but it is
conceivable that this could cause problems on Windows with anti-virus
and indexing software.

high volume.
Add detailed state information to the errors, as it is no longer being
logged downstream.
Also add the state information to mempool rejection debug message in
ProcessMessages.
Remove unnecessary direct logging in CheckTransaction,
AcceptToMemoryPool, CheckTxInputs, CScriptCheck::operator()
All status information should be returned in the CValidationState.
Relevant debug information is also added to the CValidationState using
the recently introduced debug message.
Do keep the "BUG! PLEASE REPORT THIS! ConnectInputs failed against MANDATORY but not STANDARD flags"
error as it is meant to appear as bug in the log.
Add status codes specific to AcceptToMempool procession of transactions.
These can never happen due to block validation, and must never be sent
over the P2P network. Add assertions where appropriate.
