- expose info about number of txns in unbroadcast set and whether a mempool entry's tx has passed initial broadcast - makes rpcs more informative and allows for more explicit testing, eg tracking if tx is in unbroadcast set before and after originating node connects to peers (adds this in mempool_unbroadcast.py) - adds mempool method InUnbroadcast to quickly query for tx inclusion in mempool's unbroadcast set
- before reattempting broadcast for unbroadcast txns, check they are in mempool and remove if not - this protects from memory leaks and network spam just in case unbroadcast set (incorrectly) has extra txns - check that tx is in mempool before adding to unbroadcast set to try to prevent this from happening
… entries
- mempool entry 'unbroadcast' field changes when initial broadcast is complete,
so anytime you want to compare mempool entries, wait for initial broadcast to complete
('unbroadcast' = False) otherwise it may change in between calls
- mempool_packages.py needs to do this especially because it compares entries as a whole
and compares getrawmempool with getmempoolentry

… in libevent 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 bitcoin#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.

…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.

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. ``` ================== WARNING: ThreadSanitizer: data race (pid=32335) Write of size 8 at 0x7b3c000008f0 by thread T22

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).

The previous commit added a test which would fail the
unsigned-integer-overflow sanitizer. The warning is harmless and can be
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:
