@ftrader ftrader commented May 11, 2017

This removes the leftover 'bumpfee' (RBF) regtest and client code.

There is an uncertainty in the removed wallet code - one check that depends on a 'replaced_by_txid' count has been left in as that count is still calculated. This needs careful review.

Once we have reviewed the change to src/wallet/wallet.cpp and are sure about it, I can remove the extra comments there and squash.

Port of bitcoin/#10958 - leveldb patches
26bef49 
Summary:
Includes:

  bitcoin-core/leveldb-subtree#2: Prefer std::atomic over MemoryBarrier (Pieter Wuille)
  bitcoin-core/leveldb-subtree#5: Move helper functions out of sse4.2 object (Cory Fields)
  bitcoin-core/leveldb-subtree#6: Fixes typo (Dimitris Tsapakidis)
  bitcoin-core/leveldb-subtree#10: Clean up compile-time warnings (gcc 7.1) (Matt Corallo)
  bitcoin-core/leveldb-subtree#11: fixup define checks. Cleans up some oopses from Bitcoin-ABC#5 (Cory Fields)

Removes many warnings on MacOSX of the form:

  In file included from leveldb/util/cache.cc:10:
  In file included from ./leveldb/port/port.h:14:
  In file included from ./leveldb/port/port_posix.h:47:
  ./leveldb/port/atomic_pointer.h:55:3: warning: 'OSMemoryBarrier' is deprecated: first deprecated in macOS 10.12 - Use
      std::atomic_thread_fence() from <atomic> instead [-Wdeprecated-declarations]
        OSMemoryBarrier();
        ^

The bitcoin core patches have been included in BU already by sickpig.

Test Plan: make check.  Installed and running fine.

[CI] Ensure llvm-symbolizer is available in PATH
f42e227 
Summary:
We see occasional flakiness on TSAN that gives not-so-useful output like this:
```
==5540==WARNING: failed to fork (errno 12)
==5540==WARNING: Failed to use and restart external symbolizer!
==================
WARNING: ThreadSanitizer: lock-order-inversion (potential deadlock) (pid=5540)
  Cycle in lock order graph: M100059481 (0x7fffa93419f8) => M100059482 (0x7fffa93419d0) => M100059481

  Mutex M100059482 acquired here while holding mutex M100059481 in main thread:
    #0 <null> <null> (test_bitcoin+0xeacce)
    #1 <null> <null> (test_bitcoin+0x7b9675)
    #2 <null> <null> (test_bitcoin+0x7b8e8b)
    #3 <null> <null> (test_bitcoin+0x198299)
    #4 <null> <null> (libboost_unit_test_framework.so.1.67.0+0x55dbd)
    #5 <null> <null> (libc.so.6+0x2409a)
```

Attempts to symbolize that memory manually suggests a deadlock that is already in our suppressions file.

Although clang sanitizers will default to llvm-symbolizer, it's not in our path, so it defaults to addr2line.
It's not clear if addr2line can be assumed to perform as well as llvm-symbolizer. Testing both locally
indicates they produce very similar output when suppressions files are not used, for instance.

This patch is more of an experiment to see if llvm-symbolizer is able to correctly symbolize the above logs.
If so, either the suppression will stop being flaky or we will obtain useful information to pinpoint the root
cause.

Test Plan: Run ASAN, TSAN, UBSAN on CI and make sure they still pass

Summary:
1f9d5af4f197e7cc0469a0bb25dcbc51dfa537f4 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:

This is a backport of [[bitcoin/bitcoin#20748 | core#20748]]

Test Plan:
With TSAN:
`for i in $(seq 100); do TSAN_OPTIONS=second_deadlock_stack=1: TSAN_OPTIONS=suppressions=/home/pierre/dev/bitcoin-abc/test/sanitizer_suppressions/tsan test/functional/test_runner.py interface_zmq; done`

This failure is intermittent, but relatively easy to reproduce: I was able to get it with 10 repetitions of the test, prior to adding the suppression.
