58c9b50a95 gui: Add wallet name to address book page (pablomartin4btc)
Pull request description:
It fixes bitcoin-core/gui#756.
Each address book page window it's now labeled with the wallet name they were opened with, so the user can easily identify which addresses belong to which wallet even when there are many windows opened. It's a helpful enhancement for users managing multiple wallets.

d27b9a2248 test: fix feature_init.py file perturbation (Martin Zumsande)
ad66ca1e47 init: abort loading of blockindex in case of missing height. (Martin Zumsande)
Pull request description:
When the block index database is non-contiguous due to file corruption (i.e. it contains indexes of height `x-1` and `x+1`, but not `x`), bitcoind can currently crash with an assert in `BuildSkip()` / `GetAncestor()` during `BlockManager::LoadBlockIndex()`:
```
bitcoind: chain.cpp:112: const CBlockIndex* CBlockIndex::GetAncestor(int) const: Assertion `pindexWalk->pprev' failed.
```
This PR changes it such that we instead return an `InitError` to the user.
I stumbled upon this because I noticed that the file perturbation in `feature_init.py` wasn't working as intended, which is fixed in the second commit:
* Opening the file twice in one `with` statement would lead to `tf_read` being empty, so the test wouldn't perturb anything but replace the file with a new one. Fixed by first opening for read, then for write.
* We need to restore the previous state after perturbations, so that only the current perturbation is active and not a mix of the current and previous ones.
* I also added `checkblocks=200` to the startup parameters so that corruption in earlier blocks of `blk00000.dat` is detected during init verification and not ignored.
After fixing `feature_init.py` like that I'd run into the `assert` mentioned above (so running the testfix from the second commit without the first one is a way to reproduce it).

Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/28585.
Fixes a few races within the assumeutxo tests:
- In general, `-stopatheight` can't be used with `connect_nodes` safely because the latter performs blocking assertions that are racy with the stopatheight triggering.
- Now that the snapshot chainstate is listed as `normal` after background validation, accept the final height from either chainstate.

The descriptor documentation (doc/descriptors.md) and BIP380 explicitly
require that hex-encoded public keys start with 02 or 03 (compressed) or
04 (uncompressed). However, the current parsing/inference code permit 06
and 07 (hybrid) encoding as well. Fix this.
A "version" message in the V1 protocol starts with a fixed 16 bytes:
* The 4-byte network magic
* The 12-byte zero-padded command "version" plus 5 0x00 bytes
The current code detects incoming V1 connections by just looking at the
first 12 bytes (matching an earlier version of BIP324), but 16 bytes is
more precise. This isn't an observable difference right now, as a 12 byte
prefix ought to be negligible already, but it may become observable with
future extensions to the protocol, so make the code match the
specification.
It is unclear what the goal of this check is, given that the value may
need to be set lower for the mimimum supported version of compilers that
forgot to bump the value, see
https://github.com/bitcoin/bitcoin/pull/28349#issuecomment-1745143612 .
The minimum supported compiler versions are already documented in
doc/dependencies.md and using an older compiler will already result in a
compile failure, so this check can be removed as redundant. Especially
given that it is only included in one file, where iwyu suggests to
remove it.

Pull request description:
#26742 significantly increased the http server shutdown speed, but also introduced a bug (#27722 - see https://github.com/bitcoin/bitcoin/issues/27722#issuecomment-1559453982 for steps to reproduce on master) that causes http server shutdown to halt in case of a remote client disconnection. This happens because `evhttp_request_set_on_complete_cb` is never called and thus the request is never removed from `g_requests`.
This PR fixes that bug, and improves robustness of the code by encapsulating the request tracking logic. Earlier approaches (#27909, #27245, #19434) attempted to resolve this but [imo are fundamentally unsafe](https://github.com/bitcoin/bitcoin/pull/27909#discussion_r1265614783) because of differences in lifetime between an `evhttp_request` and `evhttp_connection`.
We don't need to keep track of open requests or connections, we just [need to ensure](https://github.com/bitcoin/bitcoin/pull/19420#issue-648067169) that there are no active requests on server shutdown. Because a connection can have multiple requests, and a request can be completed in various ways (the request actually being handled, or the client performing a remote disconnect), keeping a counter per connection seems like the approach with the least overhead to me.
Fixes #27722

Extract the logic for calculating & maintaining inbound connection limits to be
a member within connman for consistency with other maximum connection limits.
Note that we now limit m_max_inbound to 0 and don't call
AttemptToEvictConnection() when we don't have any inbounds.
Previously, nMaxInbound could become negative if the user ran with a low
-maxconnections, which didn't break any logic but didn't make sense.

Currently the logic is fragmented between init and connman. Encapsulating this
logic within connman allows for less mental overhead and easier reuse in tests.

352d5eb2a9 test: getrawaddrman RPC (0xb10c)
da384a286b rpc: getrawaddrman for addrman entries (0xb10c)
Pull request description:
Inspired by `getaddrmaninfo` (#27511), this adds a hidden/test-only `getrawaddrman` RPC. The RPC returns information on all addresses in the address manager new and tried tables. Addrman table contents can be used in tests and during development.
The RPC result encodes the `bucket` and `position`, the internal location of addresses in the tables, in the address object's string key. This allows users to choose to consume or to ignore the location information. If the internals of the address manager implementation change, the location encoding might change too.
```
getrawaddrman

Pull request description:
_This is a piece of #21878, chopped off to ease review._
Peeking at the underlying socket file descriptor of `Sock` and checkig if it is `INVALID_SOCKET` is bad encapsulation and stands in the way of testing/mocking/fuzzing.
Instead use an empty `unique_ptr` to denote that there is no valid socket where appropriate or outright remove such checks where they are not necessary.
The default constructor `Sock::Sock()` is unnecessary now after recent changes, thus remove it.

bae209e387 gui: macOS, make appMenuBar part of the main app window (furszy)
e14cc8fc69 gui: macOS, do not process dock icon actions during shutdown (furszy)
Pull request description:
As the 'QMenuBar' is created without a parent window in MacOS, the app crashes when the user presses the shutdown button and, right after it, triggers any action in the menu bar.
This happens because the QMenuBar is manually deleted in the BitcoinGUI destructor but the events attached to it children actions are not disconnected, so QActions events such us the 'QMenu::aboutToShow' could try to access null pointers.
Instead of guarding every single QAction pointer inside the QMenu::aboutToShow slot, or manually disconnecting all registered events in the destructor, we can check if a shutdown was requested and discard the event.
The 'node' field is a ref whose memory is held by the main application class, so it is safe to use here. Events are disconnected prior destructing the main application object.
Furthermore, the 'MacDockIconHandler::dockIconClicked' signal can make the app crash during shutdown for the very same reason. The 'show()' call triggers the 'QApplication::focusWindowChanged' event, which is connected to the 'minimize_action' QAction, which is also part of the app menu bar, which could no longer exist.
Another cause of crashes stems from the shortcuts provided by the `appMenuBar` submenus during shutdown. For instance, executing actions like opening the information dialog (command + I) or the console dialog (command + T) lead to access null pointers. The second commit addresses and resolves these issues.
Basically, in the present setup, we create a parentless `appMenuBar` whose submenus `QActions` are connected to `qApp` events (the app's global instance). However, at the `BitcoinGUI` destructor, we manually destruct this object without properly disconnecting the events. This leaves `qApp` events, such as `focusWindowChanged`, tied to submenus' `QAction` pointers, which causes the application to crash when it attempts to access them.
Important Note:
This happened to me few times. The worst consequence was an inconsistent chain state during IBD. Which triggered a full "replay blocks" process on the next startup. Which was painfully slow.

It is possible that the client disconnects before the request is
handled. In those cases, evhttp_request_set_on_complete_cb is never
called, which means that on shutdown the server we'll keep waiting
endlessly.
By adding evhttp_connection_set_closecb, libevent automatically
cleans up those dead connections at latest when we shutdown, and
depending on the libevent version already at the moment of remote
client disconnect. In both cases, the bug is fixed.
Introduces and uses a HTTPRequestTracker class to keep track of
how many HTTP requests are currently active, so we don't stop the
server before they're all handled.
This has two purposes:
1. In a next commit, allows us to untrack all requests associated
with a connection without running into lifetime issues of the
connection living longer than the request
(see https://github.com/bitcoin/bitcoin/pull/27909#discussion_r1265614783)
2. Improve encapsulation by making the mutex and cv internal members,
and exposing just the WaitUntilEmpty() method that can be safely
used.
