fa1433ac1b rpc: Remove special case for unknown service flags (MarcoFalke)
Pull request description:
The special case to return a bit as an integer is clumsy and undocumented. Probably also irrelevant because there shouldn't currently be a non-misbehaving client that connects to Bitcoin Core and advertises an unknown service flag.
Thus, simply remove the code.

ac94141af0 validation: delay flushing undo files in syncing node case (Karl-Johan Alm)
Pull request description:
Fixes#17890. Replaces #17892.
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`.

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.

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 (...)`)

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.

Building with -Wunreachable-code-loop-increment causes a warning
due to always returning on the first iteration of the loop that
outputs errors on invalid args.
Collect all errors, and output them in a single error message
after the loop completes, resolving the warning and avoiding
popup hell by outputting a seperate message for each error.
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:
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.

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.

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.

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.

e8fa0a3d20 Fix WSL file locking by using flock instead of fcntl (Samuel Dobson)
Pull request description:
Fixes#18622
A bug in WSL means that fcntl does not exclusively lock files, allowing multiple instances of bitcoin to use the same datadir. If we instead use flock, it works correctly. Passes Travis, but testing on some OS variety would be sensible.
From what I can tell, flock and fcntl don't work with each other on linux, so it would still be possible to run a node with this code change and a node before it with the same datadir (this isn't true for Mac/FreeBSD). flock also doesn't support NFS on MacOS and linux<2.6.12 while fcntl did. See here for example: https://gavv.github.io/articles/file-locks/
If changing to flock for all systems is inadvisable, it would also be possible to just detect WSL and use flock when on that platform to avoid the bug.

c3cf2f5501 rpc/blockchain.cpp: Remove g_utxosetscan mutex that is only protecting a single atomic variable (Anthony Towns)
Pull request description:
In a few cases we need to use `std::mutex` rather than the sync.h primitives. But `std::lock_guard<std::mutex>` doesn't include the clang thread safety annotations unless you also use clang's C library, which means you can't indicate when variables should be guarded by `std::mutex` mutexes.
This adds an annotated version of `std::lock_guard<std::mutex>` to threadsafety.h to fix that, and modifies places where `std::mutex` is used to take advantage of the annotations.
It's based on top of #16112, and turns the thread safety comments included there into annotations.
It also changes the RAII classes in wallet/wallet.h and rpc/blockchain.cpp to just use the atomic<bool> flag for synchronisation rather than having a mutex that doesn't actually guard anything as well.

c57f03ce17 refactor: Replace const char* to std::string (Calvin Kim)
Pull request description:
Rationale: Addresses #19000
Some functions should be returning std::string instead of const char*.
This commit changes that.
Main benefits/reasoning:
1. The functions never return nullptr, so returning a string makes code at call sites easier to review (reviewers don't have to read the source code to verify that a nullptr is never returned)
2. All call sites convert to string anyway

Pull request description:
Tracking our instrumented mutexes (`Mutex` and `RecursiveMutex` types) requires that all involved objects should not be destroyed until after their last use. On master (ec79b5f86b) we have two problems related to the object destroying order:
- the function-local `static` `lockdata` object that is destroyed at [program exit](https://en.cppreference.com/w/cpp/utility/program/exit)
- the `thread_local` `g_lockstack` that is destroyed at [thread exit](https://en.cppreference.com/w/cpp/language/destructor)
Both cases could cause UB at program exit in so far as mutexes are used in other static object destructors.

Returning by const value is only meaningful in a specific circumstance around
user defined types. In this case, the const is not enforcing any restrictions
on the call site, so is misleading.
Instead of having these be class static functions, just make them be
standalone. Also removes WalletBatch::Recover which just passed through
to BerkeleyBatch::Recover.

The global `g_chainman` has recently been introduced in #17737. The chainstate manager is primarily needed for the assumeutxo feature, but it can also simplify testing in the future.
The goal of this pull is to make the global chainstate manager internal to validation, so that all external code does not depend on globals and that unit or fuzz tests can pass in their (potentially mocked) chainstate manager.
I suggest reviewing the pull request commit-by-commit. It should be relatively straightforward refactoring that does not change behavior at all.

b59b4504ab have GenerateNewKey and DeriveNewChildKey take a CHDChain as an argument (Andrew Chow)
Pull request description:
Largely implements the suggestion from https://github.com/bitcoin/bitcoin/pull/17484#issuecomment-560845316.
After `sethdseed` is called, the CHDChain for the old seed is kept in the wallet. It is kept on the file as a new `inactivehdseed` record and in memory in a map `m_inactive_hd_seeds`. In `LegacyScriptPubKeyMan::MarkUnusedAddresses` we check each used key's metadata for whether it was derived from an inactive seed. If it is, we then check to see how many keys after that key were derived from the inactive seed. If that number does not match the keypool parameter, we derive more keys from the inactive seed until it does match. This way we won't miss transactions belonging to keys outside of the range of the keypool initially.
The indexes and internal-ness of a key is gotten by checking it's key origin data.
Because of this change, we no longer need to wait for IBD to finish before `sethdseed` can work so that check is also removed.
A test case for this is added as well which fails on master.

Pull request description:
Followup to #18038 by amitiuttarwar which introduces the unbroadcast set: "a mechanism for the mempool to track locally submitted transactions" and decreases the frequency of rebroadcast from 10-15 minutes to 12-36 hours.
This PR addresses some of the outstanding TODOs building on top of it:
- remove `nLastResend` logic, which is used to ensure rebroadcast doesn't happen again if no new block has been mined (makes sense in 10-15 min period, but not necessary for 12-36 hour period). (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416826914))
- expose unbroadcast info via RPCs, for more informative queries and testing (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416837980))
- add sanity check to verify unbroadcast transactions still exist in mempool before rebroadcasting (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416861609))

d67055e00d Upgrade or rewrite encrypted key checksums (Andrew Chow)
c9a9ddb414 Set fDecryptionThoroughlyChecked based on whether crypted key checksums are valid (Andrew Chow)
a8334f7ac3 Read and write a checksum for encrypted keys (Andrew Chow)
Pull request description:
Adds a checksum to the encrypted key record in the wallet database so that encrypted keys can be checked for corruption on wallet loading, in the same way that unencrypted keys are. This allows for us to skip the full decryption of keys upon the first unlocking of the wallet in that session as any key corruption will have already been detected. The checksum is just the double SHA256 of the encrypted key and it is appended to the record after the encrypted key itself.
This is backwards compatible as old wallets will be able to read the encrypted key and ignore that there is more data in the stream. Additionally, old wallets will be upgraded upon their first unlocking (so that key decryption is checked before we commit to a checksum of the encrypted key) and a wallet flag set indicating that. The presence of the wallet flag lets us skip the full decryption as if `fDecryptionThoroughlyChecked` were true.
This does mean that the first time an old wallet is unlocked in a new version will take much longer, but subsequent unlocks will be instantaneous. Furthermore, corruption will be detected upon loading rather than on trying to send so wallet corruption will be detected sooner.

4444dbf4d5 gui: Remove un-actionable TODO (MarcoFalke)
Pull request description:
With encryption turned on by default for all wallets in consideration (#18889), I believe that wallet decryption will not be implemented ever or at least any time soon. So remove that TODO comment for now. If deemed important, a brainstorming issue can be opened instead.
Also remove some TODOs in the RPC console, which I don't understand. Maybe the gui was meant to show the debug log interactively? In any case, if deemed important, this should be filed as a brainstorming feature request, so that trade-offs of different solutions can be discussed.

691c817b34 Add util::Ref class as temporary alternative for c++17 std::any (Russell Yanofsky)
Pull request description:
This PR removes the `g_rpc_node` global, to get same benefits we see removing other globals and make RPC code more testable, modular, and reusable.
This uses a hybrid of the approaches suggested in #17548. Instead of using `std::any`, which isn't available in c++11, or `void*`, which isn't type safe, it uses a small new `util::Ref` helper class, which acts like a simplified `std::any` that only holds references, not values.
Motivation for writing this was to provide an simpler alternative to #18647 by Harris Brakmić (brakmic) which avoids some shortcomings of that PR (https://github.com/bitcoin/bitcoin/pull/18647#issuecomment-617878826)

to allow passing rpcwallet independently from the -rpcwallet user option, and to
move the logic to the top-level layer where most of the other option args are
handled.
to ConnectAndCallRPC() to be callable for individual connections.
This is needed for RPCs that need to be called and handled sequentially, rather
than alone or in a batch.
For example, when fetching the balances for each loaded wallet, -getinfo will
call RPC listwallets, and then, depending on the result, RPC getbalances.

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR consists of build changes only. It adds an `--enable-multiprocess` autoconf option (off by default and marked experimental), that builds new `bitcoin-node` and `bitcoin-gui` binaries. These currently function the same as existing `bitcoind` and `bitcoin-qt` binaries, but are extended in #10102 with IPC features to execute node, wallet, and gui functions in separate processes.
In addition to adding the `--enable-multiprocess` config flag, it also adds a depends package and autoconf rules to build with the [libmultiprocess](https://github.com/chaincodelabs/libmultiprocess) library, and it adds new travis configuration to exercise the build code and run functional tests with the new binaries.
The changes in this PR were originally part of #10102 but were moved into #16367 to be able to develop and review the multiprocess build changes independently of the code changes. #16367 was briefly merged and then reverted in #18588. Only change since #16367 has been dropping the `native_boost.mk` depends package which was pointed out to be no longer necessary in https://github.com/bitcoin/bitcoin/pull/16367#issuecomment-596484337 and https://github.com/bitcoin/bitcoin/pull/18588#pullrequestreview-391765649

fabea6d404 net: Run clang-format on protocol.h (MarcoFalke)
facdeea2b2 net: Remove un-actionable TODO (MarcoFalke)
Pull request description:
The first commit removes a TODO that is infeasible to solve. Currently, most (de)serializable classes in Bitcoin Core have public members. For example `CMessageHeader`, `FlatFilePos`, `CBlock`, `CTransaction`, `CCoin`, ...
So either this TODO comment should apply to all classes or to none. Fix that discrepancy by removing it from the source code for now. If deemed important, the TODO can be discussed in a brainstorming issue later.
Also run clang format on the header file in a new commit. Happy to drop this commit if it is too controversial, but I think it is trivial to review and makes the workflow of developers using clang-format-diff easier.

83f69fab3a Switch transaction table to use wallet height not node height (Russell Yanofsky)
Pull request description:
Main commit `gui: Avoid wallet tryGetBalances calls` is one-line change to `WalletModel::pollBalanceChanged` that returns early if there hasn't been a new `TransactionChanged` or `BlockTip` notification since the previous poll call. This is the same behavior that was implemented in #18160, now implemented in a simpler way.
The other commits are a straight revert of #18160, and two tweaks to avoid relying on `WalletModel::m_client_model` lifetime which were causing travis failures with earlier versions of this PR.
Motivation for this change is to be able to revert #18160 and cut down on unnecessary cross-process calls that happen when #18160 is combined with #10102

- before reattempting broadcast for unbroadcast txns, check they are in mempool and remove if not
- this protects from memory leaks and network spam just in case unbroadcast set (incorrectly) has extra txns
- check that tx is in mempool before adding to unbroadcast set to try to prevent this from happening
- expose info about number of txns in unbroadcast set and whether a mempool entry's tx has passed initial broadcast
- makes rpcs more informative and allows for more explicit testing, eg tracking if tx is in unbroadcast set
before and after originating node connects to peers (adds this in mempool_unbroadcast.py)
- adds mempool method IsUnbroadcastTx to query for tx inclusion in mempool's unbroadcast set
