Fix 2 more bottlenecks causing GUI lockups (#3169)
* Remove dataChanged call for ToAddress

This call is redundant since a long time already. It comes from a time
where there was no ToAddress column, but only a Description column which
also contained status information for coinbases. This is gone for a long
time already, so the ToAddress column has nothing included which might
change when confirmations change.

For the history:
34fa178243 splitted the Description column
into Type and ToAddress
e599246803 removed last traces of status from
the ToAddress column

* Avoid call to labelForAddress in formatTxToAddress

This speeds up sorting by address

da2f503a48 Fix largest part of GUI lockups with large wallets (#3155)
* [Qt] make sure transaction table entry gets updated after bump

* Remove unnecessary tracking of IS lock count

* Track lockedByChainLocks in TransactionRecord

* Only update record when the TX was not ChainLocked before

* Emit dataChanged for CT_UPDATED transactions

* Use plain seconds since epoch comparison in TransactionFilterProxy::filterAcceptsRow

The QDateTime::operator< calls inside TransactionFilterProxy::filterAcceptsRow
turned out to be the slowest part in the UI when many TXs are inside
the wallet. DateRoleInt allows us to request the plain seconds since epoch
which we then use to compare against dateFrom/dateTo, which are also both
stored as seconds since epoch now.

* Don't invoke updateConfirmations directly and let pollBalanceChanged handle it

* Implement AddressTableModel::labelForDestination

This one avoids converting from string to CBitcoinAddress and calling
.Get() on the result.

* Also store CBitcoinAddress object and CTxDestination in TransactionRecord

This avoids frequent and slow conversion

* Use labelForDestination when possible

This avoids unnecessary conversions

* Don't set fForceCheckBalanceChanged to true when IS lock is received

We already do this through updateTransaction(), which is also called when
an IS lock is received for one of our own TXs.

* Only update lockedByChainLocks and lockedByInstantSend when a change is possible

lockedByChainLocks can never get back to false, so no need to re-check it.
Same with lockedByInstantSend, except when a ChainLock overrides it.

* Hold and update label in TransactionRecord

Instead of looking it up in data()

* Review suggestions

* Use proper columns in dataChanged call in updateAddressBook

be127bc2ee Replace vecAskFor with a priority queue (#3147)
This avoids sorting before looping through it to figure out what to
request. The assumption that sorting would be cheap when vecAskFor is
already mostly sorted (only unsorted at the end) turned out to be false.
In reality, ~50% of CPU time was consumed by the sort when a lot of traffic
(thousands of TXs) happen.

02e1e4eff6cda0bfc24b455a7c1583394cbff6eb rpc: Add wait argument to stop (João Barbosa)

Pull request description:

  Fixes #11777. Reverts #11006. Replaces #13501.

  With this change the HTTP server will exit gracefully, meaning that all requests will finish processing and sending the response, even if this means to wait more than 2 seconds (current time allowed to exit the event loop).

  Another small change is that connections are accepted even when the server is stopping, but HTTP requests are rejected. This can be improved later, especially if chunked replies are implemented.

  Briefly, before this PR, this is the order or events when a request arrives (RPC `stop`):
   1. `bufferevent_disable(..., EV_READ)`
   2. `StartShutdown()`
   3. `evhttp_del_accept_socket(...)`
   4. `ThreadHTTP` terminates (event loop exits) because there are no active or pending events thanks to 1. and 3.
   5. client doesn't get the response thanks to 4.

  This can be verified by applying
  ```diff
       // Event loop will exit after current HTTP requests have been handled, so
       // this reply will get back to the client.
       StartShutdown();
  +    MilliSleep(2000);
       return "Bitcoin server stopping";
   }
  ```
  and checking the log output:
  ```
      Received a POST request for / from 127.0.0.1:62443
      ThreadRPCServer method=stop user=__cookie__
      Interrupting HTTP server

      msghand thread exit
      net thread exit

      ... sleep 2 seconds ...

      Waiting for HTTP event thread to exit
      Stopped HTTP server
  ```

  For this reason point 3. is moved right after all HTTP workers quit. In that moment HTTP replies are queued in the event loop which keeps spinning util all connections are closed. In order to trigger the server side close with keep alive connections (implicit in HTTP/1.1) the header `Connection: close` is sent if shutdown was requested. This can be tested by
  ```
  bitcoind -regtest
  nc localhost 18443
  POST / HTTP/1.1
  Authorization: Basic ...
  Content-Type: application/json
  Content-Length: 44

  {"jsonrpc": "2.0","method":"stop","id":123}
  ```

  Summing up, this PR:
   - removes explicit event loop exit — event loop exits once there are no active or pending events
   - changes the moment the listening sockets are removed — explained above
   - sends header `Connection: close` on active requests when shutdown was requested which is relevant when it's a persistent connection (default in HTTP 1.1) — libevent is aware of this header and closes the connection gracefully
   - removes event loop explicit break after 2 seconds timeout

2be67c7605 Merge #12324: speed up Unserialize_impl for prevector
86b47fa741408b061ab0bda784b8678bfd7dfa88 speed up Unserialize_impl for prevector (Akio Nakamura)

Pull request description:

  The unserializer for prevector uses `resize()` for reserve the area, but it's prefer to use `reserve()` because `resize()` have overhead to call its constructor many times.

  However, `reserve()` does not change the value of `_size` (a private member of prevector).

  This PR make the logic of read from stream to callback function, and prevector handles initilizing new values with that call-back and ajust the value of `_size`.

  The changes are as follows:
  1. prevector.h
  Add a public member function named 'append'.
  This function has 2 params, number of elemenst to append and call-back function that initilizing new appended values.

  2. serialize.h
  In the following two function:
  - `Unserialize_impl(Stream& is, prevector<N, T>& v, const unsigned char&)`
  - `Unserialize_impl(Stream& is, prevector<N, T>& v, const V&)`
  Make a callback function from each original logic of reading values from stream, and call prevector's `append()`.

  3. test/prevector_tests.cpp
  Add a test for `append()`.

  ## A benchmark result is following:
  [Machine]
  MacBook Pro (macOS 10.13.3/i7 2.2GHz/mem 16GB/SSD)

5aad635 Use memset() to optimize prevector::resize() (Evan Klitzke)
e46be25 Reduce redundant code of prevector and speed it up (Akio Nakamura)
f0e7aa7 Add new prevector benchmarks. (Evan Klitzke)

Pull request description:

  This branch optimizes various `prevector` operations, especially resizing vectors. While profiling the `loadblk` thread I noticed that a lot of time was being spent in `prevector::resize()` which led to this work. I have some data here indicating that it takes up **37%** of the time in `ReadBlockFromDisk()`: https://monad.io/readblockfromdisk.svg

  This branch improves things significantly. For trivial types, the new results for the prevector benchmark are:

   * `PrevectorClearTrivial` which tests `prevector::clear()` becomes 24.6x faster
   * `PrevectorDestructorTrivial` which tests `prevector::~prevector()` becomes 20.5x faster
   * `PrevectorResizeTrivial` which tests `prevector::resize()` becomes 20.3x faster

  Note that in practice it looks like the prevector is only used to contain `unsigned char` types, which is a trivial type. The benchmarks are testing a bit of an extreme case, but the changes here are motivated by the profiling data for `ReadBlockFromDisk()` I linked to above.

  The pull request here consists of a series of three commits:
   * The first adds new benchmarks but does not change the prevector code.
   * The second is from @AkioNak , and merges some prevector optimizations he submitted in #11988
   * The third optimizes `prevector::resize()` to use `memset()` when the prevector contains trivially constructible types

  Based on #13191.

  This adds SHA256 implementations that use Intel's SHA Extension instructions (using intrinsics). This needs GCC 4.9 or Clang 3.4.

  In addition to #13191, two extra implementations are provided:
  * (a) A variable-length SHA256 implementation using SHA extensions.
  * (b) A 2-way 64-byte input double-SHA256 implementation using SHA extensions.

Pull request description:

  The SSE4 and AVX2 double-SHA256-for-64-byte input code from #13191 compiles fine on 32-bit x86 systems, but the autodetection logic in sha256.cpp doesn't enable it. Fix this.

  Note that these instruction sets are only available on CPUs that support 64-bit mode as well, so it is only beneficial in the (perhaps unlikely) scenario where a 64-bit CPU is running a 32-bit Bitcoin Core binary.

* Ignore recent rejects filter for locked txes

If we had a conflicting tx in the mempool before the locked tx arrived and the locked one arrived before the corresponding islock (i.e. we don't really know it's the one that should be included yet), the locked one is going to be rejected due to a mempool conflict. The old tx is going to be removed from the mempool by an incoming islock a bit later, however, we won't be able to re-request the locked tx until the tip changes because of the recentRejects filter. This patch fixes it.

edafc71 Fix uninitialized URI in batch RPC requests (Russell Yanofsky)

Pull request description:

  This fixes "Wallet file not specified" errors when making batch wallet RPC calls with more than one wallet loaded. This issue was reported by @NicolasDorier in https://github.com/bitcoin/bitcoin/issues/11257

  Request URI is not used for anything except multiwallet request dispatching, so this change has no other effect.

18f104b97e Merge #11590: [Wallet] always show help-line of wallet encryption calls
720d9e8fa [Wallet] always show help-line of wallet encryption calls (Jonas Schnelli)

Pull request description:

  We do currently show/hide the wallet encryption RPC calls from the help if the current wallet.
  In case of an encrypted wallet, `encryptwallet` is hidden and `walletpassphrasechange`, `walletpassphrasechange` and `walletlock` do appear in the help.

  This is no longer ideal in case of multiwallet due to the fact that one may want help infos in order to target a specific wallet.

  IMO its preferable to have a static help screen (show everything always). The currently show/hidden calls do handle the possible invalid encryption-state fine.

  Fixes #11588

Pull request description:

  @sdaftuar pointed out that the version in #11487 was somewhat DoS-able as someone could feed you a valid chain that forked off the the last checkpoint block and force you to do lots of work just walking backwards across blocks for each new block they gave you. We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458.

  Includes tests from #11487.

4637f1852 moveonly: factor out headers processing into separate function (Suhas Daftuar)

Pull request description:

  Alternate to #11446.

  Disconnect outbound (non-manual) peers that serve us block headers that are already known to be invalid, but exempt compact block announcements from such disconnects.

  We restrict disconnection to outbound peers that are using up an outbound connection slot, because we rely on those peers to give us connectivity to the honest network (our inbound peers are not chosen by us and hence could all be from an attacker/sybil).  Maintaining connectivity to peers that serve us invalid headers is sometimes desirable, eg after a soft-fork, to protect unupgraded software from being partitioned off the honest network, so we prefer to only disconnect when necessary.

  Compact block announcements are exempted from this logic to comply with BIP 152, which explicitly permits nodes to relay compact blocks before fully validating them.

5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)

Pull request description:

  The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.

  The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:

  For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip.  If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes.  If after two minutes their best known block has insufficient work, we disconnect that peer.

  We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.

  We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split.  Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect.  This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.

Pull request description:

  This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman.

  Adds HasAllRelevantServices and GetRelevantServices, which check
  for NETWORK|WITNESS.

  This changes the following:
   * Removes nRelevantServices from CConnman, disconnecting it a bit
     more from protocol-level logic.
   * Replaces our sometimes-connect-to-!WITNESS-nodes logic with
     simply always requiring WITNESS|NETWORK for outbound non-feeler
     connections (feelers still only require NETWORK).
   * This has the added benefit of removing nServicesExpected from
     CNode - instead letting net_processing's VERSION message
     handling simply check HasAllRelevantServices.
   * This implies we believe WITNESS nodes to continue to be a
     significant majority of nodes on the network, but also because
     we cannot sync properly from !WITNESS nodes, it is strange to
     continue using our valuable outbound slots on them.
   * In order to prevent this change from preventing connection to
     -connect= nodes which have !WITNESS, -connect nodes are now
     given the "addnode" flag. This also allows outbound connections
     to !NODE_NETWORK nodes for -connect nodes (which was already true
     of addnodes).
   * Has the (somewhat unintended) consequence of changing one of the
     eviction metrics from the same
     sometimes-connect-to-!WITNESS-nodes metric to requiring
     HasRelevantServices.

  This should make NODE_NETWORK_LIMITED much simpler to implement.
