6f53edb Acquire cs_main before ATMP call in block_assemble bench (James O'Beirne)

Pull request description:

  Calling `bench_bitcoin` currently fails due to calling ATMP without acquiring cs_main first in the recently added block_assemble bench (bitcoin#13219).

1f9d5af tests: Add initialization order fiasco detection in Travis (practicalswift)

Pull request description:

  Add initialization order fiasco detection in Travis :)

  Context: bitcoin#17670 (comment)

  This would have caught the `events_hasher` initialization order issue introduced in bitcoin#17573  and fixed in bitcoin#17670.

  Output in case of an initialization order fiasco:

d906aaa qt: Fix regression in TransactionTableModel (Hennadii Stepanov)

Pull request description:

  Since bitcoin#17993 a crash is possible on exit.

  Steps to reproduce:
  - precondition: the old chain
  - start `bitcoin-qt`
  - wait until sync
  - on main window: Menu -> File -> Quit
  - crash

  This PR is based on ryanofsky's [suggestion](bitcoin-core/gui#7 (comment)).

  Fixes #7.

Merge bitcoin#19353: Fix mistakenly swapped "previous" and "current" …
31bdd86 
…lock orders

0ecff9d Improve "detected inconsistent lock order" error message (Hennadii Stepanov)
bbe9cf4 test: Improve "potential deadlock detected" exception message (Hennadii Stepanov)
3559934 Fix mistakenly swapped "previous" and "current" lock orders (Hennadii Stepanov)

Pull request description:

  In master (8ef15e8) the "previous" and "current" lock orders are mistakenly swapped.

  This PR:
  - fixes printed lock orders
  - improves the `sync_tests` unit test
  - makes the "detected inconsistent lock order" error message pointing to the lock location rather `tfm::format()` location.

  Debugger output example with this PR (with modified code, of course):
  ```

5fcfee6 qt: Call setParent() in the parent's context (Hennadii Stepanov)

Pull request description:

  The `setParent(parent)` internally calls `QCoreApplication::sendEvent(parent, QChildEvent)` that implies running in the thread which created the parent object. That is not the case always, and an internal assertion fails in the debug mode.

  Steps to reproduce this issue on master (007e15d) on Linux Mint 20 (x86_64):

  ```

  $ make
  $ QT_FATAL_WARNINGS=1 lldb src/qt/bitcoin-qt -- --regtest -debug=qt

Merge bitcoin#21584: Fix assumeutxo crash due to invalid base_blockhash
ee9befe 
fa340b8 refactor: Avoid magic value of all-zeros in assumeutxo base_blockhash (MarcoFalke)
fae33f9 Fix assumeutxo crash due to invalid base_blockhash (MarcoFalke)
fa5668b refactor: Use type-safe assumeutxo hash (MarcoFalke)
0000007 refactor: Remove unused code (MarcoFalke)
faa921f move-only: Add util/hash_type (MarcoFalke)

Pull request description:

  Starting with commit d6af06d, a block hash of all-zeros is invalid and will lead to a crash of the node. Can be tested by cherry-picking the test changes without the other changes.

  Stack trace (copied from bitcoin#21584 (comment)):

Merge bitcoin#25077: Fix chain tip data race and corrupt rest response
a75b779 
fac04cb refactor: Add lock annotations to Active* methods (MacroFake)
fac15ff Fix logical race in rest_getutxos (MacroFake)
fa97a52 Fix UB/data-race in RPCNotifyBlockChange (MacroFake)
fa530bc Add ChainstateManager::GetMutex(), an alias for ::cs_main (MacroFake)

Pull request description:

  This fixes two issues:

  * A data race in `ActiveChain`, which returns a reference to the chain (a `std::vector`), which is not thread safe. See also below traceback.
  * A corrupt rest response, which returns a blockheight and blockhash, which are unrelated to each other and to the result, as the chain might advance between each call without cs_main held.

  The issues are fixed by taking cs_main and holding it for the required time.

  ```

Merge bitcoin#26477: validation: fix broken maxtipage comparison
968f03e 
e4be0e9 test: add -maxtipage test for the maximum allowable value (James O'Beirne)
a451e83 fix: validation: cast now() to seconds for maxtipage comparison (James O'Beirne)

Pull request description:

  Since bitcoin@faf4487, the maxtipage comparison in IsInitialBlockDownload() has been broken, since the NodeClock::now() time_point is in the system's native denomination (nanoseconds).

  Without this patch, specifying the maximum allowable -maxtipage (9223372036854775807) results in a SIGABRT crash:

  ```
  % gdb --args ./src/bitcoind -maxtipage=9223372036854775207 -minimumchainwork=0x00 -stopatheight=30000

triggered on any commit, since the code was introduced.

For reference, the warning would happen when the separator `-` was not
present.

For example:

  GET /rest/getutxos/6a297bfa5cb8dd976ab0207a767d6cbfaa5e876f30081127ec8674c8c52b16c0_+1.json

would result in:

rest.cpp:792:77: runtime error: unsigned integer overflow: 18446744073709551615 + 1 cannot be represented in type 'size_type' (aka 'unsigned long')

faa1c3e Revert "Merge bitcoin#32343: common: Close non-std fds before exec in RunCommandJSON" (MarcoFalke)

Pull request description:

  After a fork() in a multithreaded program, the child can safely
  call only async-signal-safe functions (see [signal-safety(7)](https://www.man7.org/linux/man-pages/man7/signal-safety.7.html))
  until such time as it calls execv.

  The standard library (`std` namespace) is not async-signal-safe. Also, `throw`, isn't.

  There was an alternative implementation using `readdir` (bitcoin#32529), but that isn't async-signal-safe either, and that implementation was still using `throw`.

  So temporarily revert this feature.

  A follow-up in the future can add it back, using only async-signal-safe functions, or by using a different approach.

  Fixes bitcoin#32524
  Fixes bitcoin#33015
  Fixes bitcoin#32855

  For reference, a failure can manifest in the GCC debug mode:

  * While `fork`ing, a debug mode mutex is held (by any other thread).
  * The `fork`ed child tries to use the stdard libary before `execv` and deadlocks.

  This may look like the following:

ac76d94 
… corruption check in fees.dat

fa1d17d refactor: Use uint64_t over size_t for serialize corruption check in fees.dat (MarcoFalke)

Pull request description:

  Serialization should not behave differently on different architectures. See also the related commit 3789215.

  However, on fees.dat file corruption, 32-bit builds may run into an unsigned integer overflow and report the wrong corruption reason, or may even silently continue after the corruption.

  This is a bit hard to reproduce, because 32-bit platforms are rare and most of them don't support running the unsigned integer overflow sanitizer. So the possible options to reproduce are:

  * Run on armhf and manually annotate the code to detect the overflow
  * Run on i386 with the integer sanitizer (possibly via `podman run -it --rm --platform linux/i386 'debian:trixie'`)
  * Run the integer sanitizer on any 64-bit platform and manually replace type in the affected line by `uint32_t`

  Afterwards, the steps to reproduce are:

  ```
  export DEBIAN_FRONTEND=noninteractive && apt update && apt install curl wget htop git vim ccache -y && git clone https://github.com/bitcoin/bitcoin.git  --depth=1 ./b-c && cd b-c && apt install build-essential cmake pkg-config  python3-zmq libzmq3-dev libevent-dev libboost-dev libsqlite3-dev  systemtap-sdt-dev  libcapnp-dev capnproto  libqrencode-dev qt6-tools-dev qt6-l10n-tools qt6-base-dev  clang llvm libc++-dev libc++abi-dev   -y

  cmake -B ./bld-cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++' -DSANITIZERS=undefined,integer,float-divide-by-zero --preset=dev-mode

  cmake --build ./bld-cmake --parallel  $(nproc)

  curl -fLO 'https://github.com/bitcoin-core/qa-assets/raw/b5ad78e070e4cf36beb415d7b490d948d70ba73f/fuzz_corpora/policy_estimator_io/607473137013139e3676e30ec4b29639e673fa9b'

  ```

  The output will be something like:

  ```

  Note: This is marked a "refactor", because the code change does not affect 64-bit builds, and on the still remaining rare 32-bit builds today it is extremely unlikely to happen in production.

3281824 fuzz: prevent invalid `FRESH` entries and surface `BatchWrite` errors (Lőrinc)
780f460 fuzz: avoid invalid `AddCoin` overwrites (Lőrinc)
d7e0d51 fuzz: make `AddCoins` query view for overwrites (Lőrinc)
b8fa6f0 util: introduce `TrySub` to prevent unsigned underflow (Lőrinc)

Pull request description:

  ### Problem
  This is an alternative approach to bitcoin#34647, fixes bitcoin#34645.

  ### Fix
  First, add `CheckedSub` and use it for decrements of `m_dirty_count` and `cachedCoinsUsage`, so unsigned underflows turn into immediate failures instead of silently wrapping and only failing later.

  <details><summary>Assertion `j <= i' failed.</summary>

  ```bash

  </details>

  The coins view fuzz targets can call `AddCoin`/`AddCoins` and construct `BatchWrite` cursors in ways that violate `CCoinsViewCache` caller contracts. These invalid states can trigger `BatchWrite` `std::logic_error` and can desync dirty-entry accounting (caught by `Assume(m_dirty_count == 0)` currently).

  Make the fuzzer avoid generating invalid states instead of catching and resetting:
  * Derive `AddCoin`’s `possible_overwrite` from `PeekCoin`, so `possible_overwrite=false` is only used when the outpoint is absent - similarly to https://github.com/bitcoin/bitcoin/blob/67c0d1798e6147f48d4bafc2c9e5ff30f2a62340/src/test/fuzz/coinscache_sim.cpp#L312-L317
  - Only use `AddCoins(check=false)` when we have confirmed the txid has no unspent outputs; otherwise fall back to `check=true` so `AddCoins` determines overwrites via the view.
  - When constructing a `CoinsViewCacheCursor`, avoid setting `FRESH` when the parent already has an unspent coin, and ensure `FRESH` implies `DIRTY`.

  ### Fuzzing
  The original error could be reproduced in ~10 minutes using `coins_view_overlay`. I ran the `coins_view`, `coins_view_db`, `coins_view_overlay`, and `coinscache_sim` fuzzers for this PR overnight and they didn't fail anymore.

fa79098 test: Fix shutdown vptr race in BlockFilterIndexSync bench (MarcoFalke)

Pull request description:

  Currently, the `BlockFilterIndexSync` may fail tsan.

  Diff to reproduce:

  and then running the tsan CI pod: `MAKEJOBS="-j$(nproc)" FILE_ENV="./ci/test/00_setup_env_native_tsan.sh" ./ci/test_run_all.sh`

  After about 3 runs, it will fail. It is also possible to run in a loop inside the pod: `while TSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/tsan:halt_on_error=1:second_deadlock_stack=1" /ci_container_base/ci/scratch/build-x86_64-pc-linux-gnu/bin/bench_bitcoin -filter=BlockFilterIndexSync -sanity-check ; do true ; done`

  The output will be:

  ```
  Running with -sanity-check option, output is being suppressed as benchmark results will be useless.

  SUMMARY: ThreadSanitizer: data race on vptr (ctor/dtor vs virtual call) /ci_container_base/src/index/base.cpp:99:1 in BaseIndex::~BaseIndex()
  ==================
  ```

  Fix this by following the shutdown sequence of first stopping the index and then desctructing it, instead of doing both at the same time (stopping inside the desctructor).

  Also, apply the comment `// Shutdown sequence (c.f. Shutdown() in init.cpp)` consistently, while touching this topic of the codebase.

  Also, remove the unused `SyncWithValidationInterfaceQueue`, which is redundant to the prior `BlockUntilSyncedToCurrentChain`. See also the last comment in the pull request that introduced this: bitcoin#26188 (comment)

  > I think anything is fine here. Either keep both or delete both.

  Given that devs did not apply the redundant sync in two new cases, it seems fine to remove it.
