…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.

…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/ $ echo -n 'combo(020000000000000000000000000000000000000000000000000000000000000000)' > descriptors/input $ UBSAN_OPTIONS="print_stacktrace=1:halt_on_error=1" src/test/fuzz/descriptor_parse -runs=1 descriptors/ … pubkey.cpp:210:38: runtime error: null pointer passed as argument 1, which is declared to never be null secp256k1/include/secp256k1.h:305:3: note: nonnull attribute specified here #0 0x561c032ccf25 in CPubKey::IsFullyValid() const src/pubkey.cpp:210:12 #1 0x561c022139c3 in (anonymous namespace)::ParsePubkeyInner(Span<char const> const&, bool, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) src/script/descriptor.cpp:674:24 #2 0x561c02207680 in (anonymous namespace)::ParsePubkey(Span<char const> const&, bool, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) src/script/descriptor.cpp:730:42 #3 0x561c0220080e in (anonymous namespace)::ParseScript(Span<char const>&, (anonymous namespace)::ParseScriptContext, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) src/script/descriptor.cpp:774:23 #4 0x561c021ffb07 in Parse(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, FlatSigningProvider&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&, bool) src/script/descriptor.cpp:994:16 #5 0x561c0218d5d4 in test_one_input(std::vector<unsigned char, std::allocator<unsigned char> > const&) src/test/fuzz/descriptor_parse.cpp:20:9 … $ ``` After: ``` $ mkdir descriptors/ $ echo -n 'combo(020000000000000000000000000000000000000000000000000000000000000000)' > descriptors/input $ UBSAN_OPTIONS="print_stacktrace=1:halt_on_error=1" src/test/fuzz/descriptor_parse -runs=1 descriptors/ … Done 2 runs in 0 second(s) $ ``` ACKs for top commit: paymog: ACK 6338c02 MarcoFalke: ACK 6338c02 🕊 Tree-SHA512: bf24c404e1f64183761b057d2f210c3db85277f4415122977c315d7d6835acb5e897b5d64032615e9e44ad4a16dfe857e94481f6e4b57b6dfa8cb37adb2528a5

…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: ``` $ echo " http:// HTTP/1.1" > input $ src/test/fuzz/http_request input src/test/fuzz/http_request: Running 1 inputs 1 time(s) each.

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): ``` 2020-06-22T15:46:56Z [msghand] POTENTIAL DEADLOCK DETECTED 2020-06-22T15:46:56Z [msghand] Previous lock order was: 2020-06-22T15:46:56Z [msghand] (2) 'cs_main' in net_processing.cpp:2545 (in thread 'msghand') 2020-06-22T15:46:56Z [msghand] (1) 'g_cs_orphans' in net_processing.cpp:1400 (in thread 'msghand') 2020-06-22T15:46:56Z [msghand] Current lock order is: 2020-06-22T15:46:56Z [msghand] (1) 'g_cs_orphans' in net_processing.cpp:2816 (in thread 'msghand') 2020-06-22T15:46:56Z [msghand] (2) 'cs_main' in net_processing.cpp:2816 (in thread 'msghand') Assertion failed: detected inconsistent lock order for 'cs_main' in net_processing.cpp:2816 (in thread 'msghand'), details in debug log.

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.
