This needs rebase. Is it still relevant?

…eprecated zeromq api functions

f1bd03e [depends, zmq, doc] upgrade zeromq to 4.2.5 and avoid deprecated zeromq api functions (mruddy)

Pull request description:

  Upgrade the ZeroMQ dependency from version 4.2.3 to the latest stable version 4.2.5.

  This PR Follows the lead of bitcoin/bitcoin#11986.

  I upgraded both patch files to correspond to the version `4.2.5` libzmq files.
  I assume doing so is still necessary and correct.

  Without updating the patch line numbers, things appear to work, but you get extra log messages while building `depends` because things don't exactly match, e.g.:
  ```
  /bitcoin/depends> make zeromq
  Extracting zeromq...
  /bitcoin/depends/sources/zeromq-4.2.5.tar.gz: OK
  Preprocessing zeromq...
  patching file src/windows.hpp
  Hunk ElementsProject#1 succeeded at 58 (offset 3 lines).
  patching file src/thread.cpp
  Hunk ElementsProject#1 succeeded at 307 with fuzz 2 (offset 87 lines).
  Hunk ElementsProject#2 succeeded at 323 with fuzz 2 (offset 90 lines).
  ```
  Updating the patches seemed cleaner, so I did it. Note that libzmq had some whitespace changes, so that's why the updated patches do too.

  More info: https://github.com/zeromq/libzmq/releases/tag/v4.2.5

  tags: libzmq, zmq, 0mq

This is because the transaction contains nValue in txout that have empty commitment. It is considered 'not explicit', but it is also not confidential.

To me, it seems that empty nValue (empty commitment) is not valid at all, and probably this should have been caught in the transaction decoding code.

8d22ab0 ci: Enable address sanitizer (ASan) stack-use-after-return checking (practicalswift)

Pull request description:

  Enable address sanitizer (ASan) stack-use-after-return checking (`detect_stack_use_after_return=1`).

  Example:

  ```
  #include <iostream>
  #include <string>

  const std::string& get_string(int i) {
      return std::to_string(i);
  }

  int main() {
      std::cout << get_string(41) << "\n";
  }
  ```

  Without address sanitizer (ASan) stack-use-after-return checking:

  ```
  $ ./stack-use-after-return

  $
  ```

  With address sanitizer (ASan) stack-use-after-return checking:

  ```
  $ ASAN_OPTIONS="detect_stack_use_after_return=1" ./stack-use-after-return

4320623 tests: Add script checking for deterministic line coverage (practicalswift)

Pull request description:

  Add script checking for deterministic line coverage in unit tests.

  Context: #14343 ("coverage reports non-deterministic")

  When the coverage is deterministic this script can be invoked from Travis to guard against regressions, but left inactive for now.

  Output in case of determinism:

  ```
  $ contrib/test_deterministic_coverage.sh 2
  [2019-01-30 20:08:46] Measuring coverage, run #1 of 2
  [2019-01-30 20:10:45] Measuring coverage, run #2 of 2

  Coverage test passed: Deterministic coverage across 2 runs.
  ```

  Output in case of non-determinism:

  ```
  $ contrib/test_deterministic_coverage.sh 2
  [2019-01-30 20:08:46] Measuring coverage, run #1 of 2
  [2019-01-30 20:10:45] Measuring coverage, run #2 of 2

  The line coverage is non-deterministic between runs.

  The test suite must be deterministic in the sense that the set of lines executed at least
  once must be identical between runs. This is a neccessary condition for meaningful coverage
  measuring.

c061be1 tests: Mark unit test blockfilter_index_initial_sync as non-deterministic (practicalswift)

Pull request description:

  Mark unit test `blockfilter_index_tests/blockfilter_index_initial_sync` as non-deterministic.

  Before this PR:

  ```
  $ contrib/devtools/test_deterministic_coverage.sh 500
  [2019-06-04 09:58:57] Measuring coverage, run #1 of 500
  [2019-06-04 10:00:33] Measuring coverage, run #2 of 500
  [2019-06-04 10:02:19] Measuring coverage, run #3 of 500

  The line coverage is non-deterministic between runs. Exiting.

  The test suite must be deterministic in the sense that the set of lines executed at least
  once must be identical between runs. This is a necessary condition for meaningful
  coverage measuring.

  The test suite must be deterministic in the sense that the set of lines executed at least
  once must be identical between runs. This is a necessary condition for meaningful
  coverage measuring.

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

Pull request description:

  Add initialization order fiasco detection in Travis :)

  Context: bitcoin/bitcoin#17670 (comment)

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

  Output in case of an initialization order fiasco:

…s (descriptor_parse)

6338c02 tests: Fix fuzzing harness for descriptor parsing (descriptor_parse) (practicalswift)

Pull request description:

  Fix bug in the descriptor parsing fuzzing harness (`descriptor_parse`) by making sure `secp256k1_context_verify` is properly initialized (via `ECCVerifyHandle`).

  Background:

  When fuzzing `Parse(…)` with `libFuzzer` I eventually reached the test case `combo(020000000000000000000000000000000000000000000000000000000000000000)`. That input triggers a call to `CPubKey::IsFullyValid()` which in turns requires an initialized `secp256k1_context_verify`.

  The fuzzing harness did not fulfil that pre-condition prior to this commit (sorry, my fault!) :)

  Before:

  ```
  $ mkdir descriptors/

…event when handling PROXY requests

20d31bd tests: Avoid fuzzer-specific nullptr dereference in libevent when handling PROXY requests (practicalswift)

Pull request description:

  Avoid constructing requests that will be interpreted by libevent as PROXY requests to avoid triggering a `nullptr` dereference. Split out from #19074 as suggested by MarcoFalke.

  The dereference (`req->evcon->http_server`) takes place in `evhttp_parse_request_line` and is a consequence of our hacky but necessary use of the internal function `evhttp_parse_firstline_` in the `http_request` fuzzing harness.

  The suggested workaround is not aesthetically pleasing, but it successfully avoids the troublesome code path.

  `" http:// HTTP/1.1\n"` was a crashing input prior to this workaround.

  Before this PR:

  ```

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):

This changed the node pruning logic and moved test/functional/feature_blockfilterindex_prune.py
to test/functional/feature_index_prune.py.

Please verify that:
1. I migrated the test correctly
2. The magic numbers in the test look fine

With respect to ElementsProject#2: I believe the magic numbers are wrong. I previously had to tweak them heavily
in commit 1278b31. I don't think I did it correctly then, and so I don't believe them to be correct now.

To summarize what this tweaking was: I changed the magic numbers in the test to work properly,
but I suspect that in changing them, I may have nullified what the test was testing.

It's very possible that the reason the test was failing was because of an underlying bug with the pruning
in elements which we have to fix, rather than just being an issue with the test itself.

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.

  ```
