769ee5fa0011ae658770586442715452a656559d Merge BigEndian functionality into CustomUintFormatter (Pieter Wuille)
Pull request description:
The next step of changes from #10785.
This:
* Adds support for enum serialization to `CustomUintFormatter`, used in `CAddress` for service flags.
* Merges `BigEndian` into `CustomUintFormatter`, used in `CNetAddr` for port numbers.
* Converts everything (except wallet and gui) to use the new serialization framework.

fabea6d404571d046365f4f083da3569d2cbf4f7 net: Run clang-format on protocol.h (MarcoFalke)
facdeea2b25ef36e37b6ada58ea390a72d11a4b2 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.

WalletModel::pollBalanceChanged
d3a56be77a9d112cde4baef4314882170b9f228f Revert "gui: Avoid Wallet::GetBalance in WalletModel::pollBalanceChanged" (Russell Yanofsky)

83f69fab3a1ae97c5cff8ba1e6fd191b0fa264bb 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
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).

the node by adding the required check and add a test.

The "A fatal internal error occurred, see debug.log for details" is
redundant because init.cpp will already show an InitError with a better
error message as well as the hint to check the debug.log

2896c412fadbc03916a33028f4f50fd87ac48edb Do not answer GETDATA for to-be-announced tx (Pieter Wuille)
f2f32a3dee9a965c8198f9ddd3aaebc627c273e4 Push down use of cs_main into FindTxForGetData (Pieter Wuille)
c6131bf407c1ada78a0e5509a702bc7da0bfd57d Abstract logic to determine whether to answer tx GETDATA (Pieter Wuille)
Pull request description:
This PR intends to improve transaction-origin privacy.
In general, we should try to not leak information about what transactions we have (recently) learned about before deciding to announce them to our peers. There is a controlled transaction dissemination process that reveals our transactions to peers that has various safeguards for privacy (it's rate-limited, delayed & batched, deterministically sorted, ...), and ideally there is no way to test which transactions we have before that controlled process reveals them. The handling of the `mempool` BIP35 message has protections in this regard as well, as it would be an obvious way to bypass these protections (handled asynchronously after a delay, also deterministically sorted).
However, currently, if we receive a GETDATA for a transaction that we have not yet announced to the requester, we will still respond to it if it was announced to *some* other peer already (because it needs to be in `mapRelay`, which only happens on the first announcement). This is a slight privacy leak.
Thankfully, this seems easy to solve: `setInventontoryTxToSend` keeps track of the txids we have yet to announce to a peer - which almost(*) exactly corresponds to the transactions we know of that we haven't revealed to that peer. By checking whether a txid is in that set before responding to a GETDATA, we can filter these out.
(*) Locally resubmitted or rebroadcasted transactions may end up in setInventoryTxToSend while the peer already knows we have them, which could result in us incorrectly claiming we don't have such transactions if coincidentally requested right after we schedule reannouncing them, but before they're actually INVed. This is made even harder by the fact that filterInventoryKnown will generally keep known reannouncements out of setInventoryTxToSend unless it overflows (which needs 50000 INVs in either direction before it happens).
The condition for responding now becomes:
```
(not in setInventoryTxToSend) AND
(
(in relay map) OR
(
(in mempool) AND
(old enough that it could have expired from relay map) AND
(older than our last getmempool response)
)
)
```

38c3dd9c706e7e84b2a4dbaf1424a3f1c3b694fc docs: Add notes on how to diasble rpc timeout in functional tests while attatching gdb. (codeShark149)
784ae096259955ea7a294114f5c021c9489d2717 test: Add capability to disable RPC timeout in functional tests. (codeShark149)
Pull request description:
Many times, especially while debugging RPC callbacks to core using gdb, the test timeout kicks in before the response can get back. This can be annoying and requires restarting the functional test as well as gdb attachment.
This PR adds a `--notimeout` flag into `test_framework` and sets the `rpc_timeout` accordingly if the flag is set.
The same effect can be achieved with newly added `--factor` flag but keeping a separate flag that explicitly disables the timeout can be easier for new testers to find it out and separates its purpose from the `--factor` flag.
Requesting review ryanofsky jnewbery as per the IRC discussion.
Update: After initial round of review, the approach is modified to accommodate the functionality in already existing `--factor` flag. `--factor` is changed to `--timeout-factor` to express its intent better.

8d306862ef077f2a71931372dd6a2efa05188c84 ci: Add fuzzbuzz integration (practicalswift)
Pull request description:
Add fuzzbuzz integration.
Just like #15338 enabled optional FreeBSD building via Cirrus CI (`.cirrus.yml`) this PR adds optional fuzzing via fuzzbuzz (`.fuzzbuzz.yml`).
Having this merged makes is easier for people to fuzz Bitcoin Core (via their forked repos) using their fuzzbuzz account and then hopefully submit coverage increasing corpus additions upstreams to to https://github.com/bitcoin-core/qa-assets.
Historically it has been mostly been me and MarcoFalke who submit test cases to `qa-assets`, but with this change hopefully more people will join the hunt for coverage increasing fuzzing inputs :)

0000ea32656833efa3d2ffd9bab66c88c83334f0 test: Add test for GetRandMillis and GetRandMicros (MarcoFalke)
fa0e5b89cf742df56c6c8f49fe9b3c54d2970a66 Add templated GetRandomDuration<> (MarcoFalke)
Pull request description:
A naive implementation of this template is dangerous, because the call site might accidentally omit the template parameter:
```cpp
template <typename D>
D GetRandDur(const D& duration_max)
{
return D{GetRand(duration_max.count())};
}
BOOST_AUTO_TEST_CASE(util_time_GetRandTime)
{
std::chrono::seconds rand_hour = GetRandDur(std::chrono::hours{1});
// Want seconds to be in range [0..1hour), but always get zero :((((
BOOST_CHECK_EQUAL(rand_hour.count(), 0);
}
```
Luckily `std::common_type` is already specialised in the standard lib for `std::chrono::duration` (https://en.cppreference.com/w/cpp/chrono/duration/common_type). And its effect seem to be that the call site must always specify the template argument explicitly.
So instead of implementing the function for each duration type by hand, replace it with a templated version that is safe to use.

ACK 050e2ee6f28e7b31c167013be7313726e34084e9 - I see why we didn't hit this on master. We are installing the `clang-8` packages for the tsan job. However on the 0.20 branch we are still just installing `clang`, which is 3.8.

746736639e6d05acdb85c866d4c605c947d4c500 [net processing] Only send a getheaders for one block in an INV (John Newbery)
Pull request description:
Headers-first is the primary method of announcement on the network. If a node fell back sending blocks by inv, it's probably for a re-org. The final block hash provided should be the highest, so send a getheaders and then fetch the blocks we need to catch up.
Sending many GETHEADERS messages to the peer would cause them to send a large number of potentially large HEADERS messages with redundant data, which is a waste of bandwidth.

fab6d060ce5f580db538070beec1c5518c8c777c test: Add unregister_validation_interface_race test (MarcoFalke)
Pull request description:
When a validationinterface has itself unregistered in one thread, but is about to get executed in another thread [1], there is a race:
* The validationinterface destructing itself
* The validationinterface getting dereferenced for execution
[1] https://github.com/bitcoin/bitcoin/blob/64139803f1225dab26197a20314109d37fa87d5f/src/validationinterface.cpp#L82-L83
This happens in the miner. More generally it happens everywhere where at least one thread is generating notifications and another one is unregistering a validationinterface.
This issue has been fixed in commit ab31b9d6fe7b39713682e3f52d11238dbe042c16, but the fix has not been applied to the miner.
Example where this happened in practice: https://travis-ci.org/github/bitcoin/bitcoin/jobs/675322230#L4414

Instruct the linker to set the major & minor subsystem versions in the PE
header to 6 & 1 (NT 6.1 which corresponds to Windows 7). Similar to
macOS, the binary will now refuse to run on unsupported versions of
Windows.

This is achieved by switching to a shared_ptr.
Also, switch the validationinterfaces in the tests to use shared_ptrs
for the same reason.
