Merge #19100: refactor: Combine GetWalletForJSONRPCRequest and EnsureWalletIsAvailable functions
f42f5e58f5 refactor: Combine GetWalletForJSONRPCRequest and EnsureWalletIsAvailable functions (Russell Yanofsky)

Pull request description:

  This simplifies control flow and also helps get rid of the ::vpwallets variable in #19101 since EnsureWalletIsAvailable doesn't have access to the request context.

gui: add missing translation.h include to fix build
After #19176, building the gui on Bionic is failing with:

```bash
  CXX      qt/qt_libbitcoinqt_a-guiutil.o
qt/bitcoin.cpp: In function 'int GuiMain(int, char**)':
qt/bitcoin.cpp:460:35: error: 'Untranslated' was not declared in this scope
node->initError(strprintf(Untranslated("Error parsing command line arguments: %s\n"), error));

The merge commit also failed to compile with the same error:

77b79fa6ef refactor: Error message bilingual_str consistency (Wladimir J. van der Laan)

Pull request description:

  A straightforward and hopefully uncontroversial refactor to improve consistency.

  - Move the decision whether to translate an individual error message to where it is defined. This simplifies call sites: no more `InitError(Untranslated(SomeFunction(...)))`.

  - Make all functions in `util/error.h` consistently return a   `bilingual_str`. We've decided to use this as error message type so let's roll with it.

  This has no functional changes: no messages are changed, no new translation messages are defined.

  Also make a function static that can be static.

8fe63e5654 Increase robustness against UB. Thanks to elichai2 who noted that the literal '1' is a signed integer, and that shifting a signed 32-bit integer by 31 bits causes an overflow and yields undefined behaviour. While 'scalar_low_impl''s 'secp256k1_scalar_cadd_bit' is only used for testing purposes and currently the 'bit' parameter is only 0 or 1, it is better to avoid undefined behaviour in case the used domain of 'secp256k1_scalar_cadd_bit' expands.

Merge #19069: refactor: replace pointers by references within tx_verify.{h,cpp}
b00266fe0c refactor: replace pointers by references within tx_verify.{h,cpp} (Sebastian Falbesoner)

Pull request description:

  This PR gets rid of another unnecessary use of raw pointers, similar to PR #19053 (see also issue #19062 where useful commands for finding potential candidates are listed) but in the tx verification module.

  For the functions `CalculateSequenceLocks()` and `SequenceLocks()`, the  `prevHeights` vector parameter type is changed to be passed as a reference. Note that there were no checks for null pointers -- if one would pass `nullptr` to one of the functions, the following line would immediately lead to a crash:

Merge #18826: Expose txinwitness for coinbase in JSON form from RPC
34645c4dd0 Test txinwitness is accessible on coinbase vin (Rod Vagg)
3e4421070a Expose txinwitness for coinbase in JSON form (Rod Vagg)

Pull request description:

  ## Rationale

  The CLI can provide you with everything about transactions and blocks that you need to reconstruct the block structure and raw block itself **except** for the witness commitment nonce which is stored in the `scriptWitness` of the coinbase and is not printed. You could manually parse the raw `"hex"` fields for transactions if you really wanted to, but this seems to defeat the point of having a JSONification of the raw block/transaction data.

  Without the nonce you can't:

  1. calculate and validate the witness commitment yourself, you can generate the witness tx merkle root but you don't have the nonce to combine it with
  2. reconstruct the raw block form because you don't have `scriptWitness` stack associated with the coinbase (although you know how big it will be and can guess the common case of `[0x000...000]`)

  I'm building some archiving tooling for block data and being able to do a validated two-way conversion is very helpful.

  ## What

  This PR simply makes the `txinwitness` field not dependent on whether we are working with the coinbase or not. So you get it for the coinbase as well as the rest.

  ## Examples

  Common case of a `[0x000...000]` nonce: 00000000000000000000140a7289f3aada855dfd23b0bb13bb5502b0ca60cdd7

  ```json
        "vin": [
          {

  ## Alternatives

  This field could be renamed for the coinbase, `"witnessnonce"` perhaps. It could also be omitted when null/zero (`0x000...000`).

  ## Tests

  This didn't break any tests and I couldn't find an obvious way to include a test for this. If this is desired I'd apreicate some pointers.

Merge #19132: qt: lock cs_main, m_cached_tip_mutex in that order

Pull request description:

  Always lock the mutexes `cs_main` and `m_cached_tip_mutex` in
  the same order: `cs_main`, `m_cached_tip_mutex`. Otherwise we may end up
  in a deadlock.

  `ClientModel::m_cached_tip_blocks` is protected by
  `ClientModel::m_cached_tip_mutex`. There are two access paths that
  lock the two mutexes in opposite order:

  ```
  validation.cpp:2868 CChainState::ActivateBestChain(): lock cs_main
  validation.cpp:2916 CChainState::ActivateBestChain(): call uiInterface.NotifyBlockTip()
  ui_interface.cpp:52 CClientUIInterface::NotifyBlockTip(): go deep in boost
  ...
  qt/clientmodel.cpp:255 BlockTipChanged(): lock m_cached_tip_mutex
  ```

  and

  ```
  qt/clientmodel.cpp:119 ClientModel::getBestBlockHash(): lock m_cached_tip_mutex
  qt/clientmodel.cpp:121 ClientModel::getBestBlockHash(): call m_node.getBestBlockHash()
  interfaces/node.cpp:200 NodeImpl::getBestBlockHash(): lock cs_main
  ```

  From `debug.log`:

  ```
  POTENTIAL DEADLOCK DETECTED
  Previous lock order was:
   m_cs_chainstate validation.cpp:2851
   (1) cs_main validation.cpp:2868
   ::mempool.cs validation.cpp:2868
   (2) clientmodel->m_cached_tip_mutex qt/clientmodel.cpp:255

Pull request description:

  There are predefined interruption points for `boost::thread`: https://www.boost.org/doc/libs/1_71_0/doc/html/thread/thread_management.html#interruption_points

  However, non-boost threads such as `std::thread` or the `main()` thread can obviously not be interrupted. So remove all unused boost/thread from methods that are never executed in a `boost::thread`.

  Most of them were accompanied by a `ShutdownRequested` anyway. So even if the current thread was a `boost::thread`, the interruption point would be redundant. (We only interrupt threads during shutdown)

Merge #19053: refactor: replace CNode pointers by references within net_processing.{h,cpp}
8b3136bd30 refactor: replace CNode pointers by references within net_processing.{h,cpp} (Sebastian Falbesoner)

Pull request description:

  This PR is inspired by a [recent code review comment](https://github.com/bitcoin/bitcoin/pull/19010#discussion_r426954791) on a PR that introduced new functions to the net_processing module. The point of the discussion was basically that whenever we pass something not by value (in the concrete example it was about `CNode*` and `CConnman*`) we should either use
  * a pointer (```CType*```) with null pointer check or
  * a reference (```CType&```)

  To keep things simple, this PR for a first approach
  * only tackles `CNode*` pointers
  * only within the net_processing module, i.e. no changes that would need adaption in other modules
  * keeps the names of the variables as they are

  I'm aware that PRs like this are kind of a PITA to review, but I think the code quality would increase if we get rid of pointers without nullptr check -- bloating up the code by adding all the missing checks would be the worse alternative, in my opinion.

  Possible follow-up PRs, in case this is received well:
  * replace CNode pointers by references for net module
  * replace CConnman pointers by references for net_processing module
  * ...

  Data files (`{blk|rev}<number>.dat`) pre-allocate space as they are written, and then trims down to the final size once they move on to the next sequence ("finalized flush"). The code currently assumes (incorrectly) that blk and rev files finish at the same time, but because blk files are written as blocks come in, and rev files are written in block height order, rev files end up being written to for awhile after moving on to the next block file, resulting in pre-allocation and waste of up to 1 MB of space per rev file.

  The exact point at which rev file writing finishes is the highest height block found inside the corresponding block file, which is already available in the CBlockFileInfo vector. This PR moves finalized flushing of undo files to to directly after the undo data for the previous block file has been written.

  There is a branch with annotation that demonstrates how this is handling flushing here: https://github.com/kallewoof/bitcoin/tree/200124-rev-files-annotated

eea8114657 build: Enable unreachable-code-loop-increment (Jonathan Schoeller)
d15db4b1fc refactor: Fix unreachable code in init arg checks (Jonathan Schoeller)

Pull request description:

  Closes: #19017

  In #19015 it's been suggested that we add some new compiler warnings to our build. Some of these, such as `-Wunreachable-code-loop-increment`, generate warnings. We'll likely want to fix these up if we're going to turn these warnings on.

  ```shell
  init.cpp:969:5: warning: loop will run at most once (loop increment never executed) [-Wunreachable-code-loop-increment]
       for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) {
       ^~~
   1 warning generated.
   ```
   aa8d76806c/src/init.cpp (L968-L972)

  To fix this, collect all errors, and output them in a single error message after the loop completes. This resolves the unreachable code warning, and avoids popup hell that could result from outputting a seperate message for each error or warning one by one.

  Telling from the line numbers, it looks like `nMisbehavior` wrapped around.

  Fix that by calling `StopNodes` after each exec, which should clear the node state and thus `nMisbehavior`.

ActivateBestChain (ABC) is only called in the "msghand" or one of the
RPC threads, neither of which is a boost::thread. However, ABC is also
called in ThreadImport (which currently happens to be a boost::thread).
In all cases, the interruption_point is redundant with the breakpoint in
ABC that triggers when ShutdownRequested()

VerifyDB is only called in the main thread ("init") or one of the RPC
threads, neither of which is a boost::thread.

7eaf86d3bf trivial: Suggested cleanups to surrounding code (Russell Yanofsky)
b604c5c8b5 wallet: Minimal fix to restore conflicted transaction notifications (Russell Yanofsky)

Pull request description:

  This fix is a based on the fix by Antoine Riard (ariard) in https://github.com/bitcoin/bitcoin/pull/18600.

  Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd and 7e89994133 from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325.

  The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.

  Fixes #18325

fa7b885f51 walletdb: Remove unsed boost/thread (MarcoFalke)
5555d978b0 wallet: Make PeriodicFlush uninterruptible (MarcoFalke)

Pull request description:

  The `boost::this_thread::interruption_point()` in the code base currently block the replacement of `boost::thread` with `std::thread`. [1]

  Remove them from the wallet because they are either unused or useless.

  The feature to interrupt a periodic flush is useless because all wallets have just been flushed 9ccaee1d5e/src/init.cpp (L194) and another flush should be a noop. Also, they will be flushed again shortly after 9ccaee1d5e/src/init.cpp (L285), so even if repeated flushes weren't a noop, doing 3 instead of 2 shouldn't matter too much at this point. Also, the wallet is flushed every two seconds in the worst case, so if this is an expensive operation, that period should be readjusted. (Or bdb should be removed altogether #18916)

  [1] Replacement of `boost::thread` with `std::thread` should happen because:

  * The boost thread dependency is slow to compile
  * Boost thread is less maintained than the standard lib
  * Boost thread is mostly redundant to the standard lib
  * Global interruption points via exceptions are hard to keep track of during review and easy to get wrong during runtime (e.g. accidental `catch (...)`)

Merge #13204: Faster sigcache nonce
152e8baf08 Use salted hasher instead of nonce in sigcache (Jeremy Rubin)
5495fa5850 Add Hash Padding Microbenchmarks (Jeremy Rubin)

Pull request description:

  This PR replaces nonces in two places with pre-salted hashers.

  The nonce is chosen to be 64 bytes long so that it forces the SHA256 hasher to process the chunk. This leaves the next 64 (or 56 depending if final chunk) open for data. In the case of the script execution cache, this does not make a big performance improvement because the nonce was already properly padded to fit into one buffer, but does make the code a little simpler. In the case of the sig cache, this should reduce the hashing overhead slightly because we are less likely to need an additional processing step.

  I haven't benchmarked this, but back of the envelope it should reduce the hashing by one buffer for all combinations except compressed public keys with compact signatures.

qt: lock cs_main, m_cached_tip_mutex in that order
Always lock the mutexes `cs_main` and `m_cached_tip_mutex` in
the same order: `cs_main`, `m_cached_tip_mutex`. Otherwise we may end up
in a deadlock.

`ClientModel::m_cached_tip_blocks` is protected by
`ClientModel::m_cached_tip_mutex`. There are two access paths that
lock the two mutexes in opposite order:

```
validation.cpp:2868 CChainState::ActivateBestChain(): lock cs_main
validation.cpp:2916 CChainState::ActivateBestChain(): call uiInterface.NotifyBlockTip()
ui_interface.cpp:52 CClientUIInterface::NotifyBlockTip(): go deep in boost
...
qt/clientmodel.cpp:255 BlockTipChanged(): lock m_cached_tip_mutex
```

and

```
qt/clientmodel.cpp:119 ClientModel::getBestBlockHash(): lock m_cached_tip_mutex
qt/clientmodel.cpp:121 ClientModel::getBestBlockHash(): call m_node.getBestBlockHash()
interfaces/node.cpp:200 NodeImpl::getBestBlockHash(): lock cs_main
```

From `debug.log`:

```
POTENTIAL DEADLOCK DETECTED
Previous lock order was:
 m_cs_chainstate validation.cpp:2851
 (1) cs_main validation.cpp:2868
 ::mempool.cs validation.cpp:2868
 (2) clientmodel->m_cached_tip_mutex qt/clientmodel.cpp:255
Current lock order is:

Pull request description:

  This PR is a follow up to #18038 which introduced the idea of an unbroadcast set & focuses mostly on documentation updates and test fixes. One small functionality update to not throw an expected error in `LoadMempool` when you upgrade software versions.

  #18895 is another follow up to that addresses other functionality updates.

  Background context:
  The unbroadcast set is a mechanism for the mempool to track locally submitted transactions (via wallet or RPC). The node does a best-effort of delivering the transactions to the network via retries every 10-15 minutes until either a `GETDATA` is received or the transaction is removed from the mempool.

    Code review ACK f871f15c9d. Changes look good and thanks for updating. In future would recommend using clang-format-diff and following [coding style](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#coding-style-c) notes, because it's atypical to indent namespace content, or indent protected keywords or put spaces around ::. Also it's fragile to define test setup class in a namespace, but test setup methods outside of the namespace and inside the test fixture instead. Would be simpler to just define the testing setup completely before using it without a namespace like: 8ad5f1c376/src/test/rpc_tests.cpp (L23) and it would have been a slightly smaller change too.

fa5894f7f5 DNS seeds: wait for 5m instead of 11s if 1000+ peers are known (Anthony Towns)

Pull request description:

  Changes the logic for querying DNS seeds: after this PR, if there's less than 1000 entries in addrman, it will still usually query DNS seeds after 11s (unless the first few peers tried mostly succeed), but if there's more than 1000 entries it won't try DNS seeds until 5 minutes have passed without getting multiple outbound peers. (If there's 0 entries in addrman, it will still immediately query the DNS seeds). Additionally, delays querying DNS seeds while the p2p network is not active.

  Fixes #15434

Merge #17993: gui: Balance/TxStatus polling update based on last block hash.
a06e845e82 BlockTip struct created and connected to notifyHeaderTip and notifyBlockTip signals. (furszy)
2f867203b0 Added best block hash to the NotifyHeaderTip and NotifyBlockTip signals. (furszy)

Pull request description:

  Rationale:

  The height based polling in the GUI is an issue on chain reorgs. Any new tip signal with the same height as the one that it's cached in the model was not triggering the GUI update (interpreting it as the same same block when it could receive a different one). Ending up with bad information presented in the GUI.

  This PR essentially changes the last cached height to be a last cached block hash.

  ---

  Old historical information of this PR.

  As the tip height is cached and updated via signaling in clientModel, there is no need to continue locking `cs_main` on every balance poll (`m_node.getNumBlocks()` method call).

  Extra topic:

  Would suggest to change the `cachedNumBlocks` field inside `walletModel` to a more understandable name, maybe `nLastBalanceUpdateHeight`.

  And finally, this will have the equal height reorg issue mentioned [here](https://github.com/bitcoin/bitcoin/pull/17905#issuecomment-577324304), whatever is presented to fix it, this should use the same flow too.

  **[Edit - 24/01/2020]**

  Have added #[17905](https://github.com/bitcoin/bitcoin/pull/17905#issuecomment-577324304) comment fix here too.
