This commit removes unnecessary mutexes (simple locking mechanisms) from two internal Bitcoin Core fuzz test files. Fuzz tests are automated testing tools, not part of the live Bitcoin network software. The change is a code cleanup: the de…
240d5f74by marcofleon+5−92 filesThis commit removes a fuzz-test helper that built a UniValue from hard-coded constants and replaces it with parsing a UniValue from random fuzz data. It only affects test code and does not change production behavior or fix a security vulne…
9f3e4272by marcofleon+2−143 filesThis commit removes mutexes (thread-safety locks) from two internal Bitcoin Core fuzz-test helpers. Fuzz tests are automated test harnesses, not production code, and the commit explains that the locks were unnecessary because fuzz targets …
48df0939by marcofleon+4−82 filesThis commit only changes a fuzz test (an automated testing harness) for Bitcoin Core's database wrapper. It reduces how many read operations each simulated worker thread performs during the test, which makes the test run faster, and increa…
a4c3b003by marcofleon+7−21 fileThis change only affects an internal fuzz test (automated randomized testing) for orphan transaction handling. It prevents the fuzz test from creating unrealistically huge blocks that could cause the test to time out. There is no change to…
004a7e3cby marcofleon+4−01 fileThis commit only adds a new automated test to Bitcoin Core. It does not change any production code. The test checks that when a node restarts after pruning a stale side-chain block, the internal block-tracking data structure does not incor…
3f44f9aeby marcofleon+40−02 filesThis commit fixes a bug where Bitcoin Core could crash on startup with a failed internal consistency check. The crash happened when a node had 'pruned' old block data while also having some header-only blocks, causing the program to incorr…
0e4b0bacby marcofleon+3−11 fileThis commit only changes a test file. It improves an existing functional test that exercises a known undefined-behavior bug in Bitcoin Core's block index handling. The test now uses a separate node, creates a three-way block race instead o…
20ae9b98by marcofleon+31−181 fileThis commit fixes a low-level memory-handling bug in Bitcoin Core's startup code. When loading the chain tip, the program was changing a value (nSequenceId) that is also used to sort a set of candidate blocks, while the block was still in …
854a6d5aby marcofleon+45−235 filesThis commit removes a redundant function call and its assertion from the snapshot activation code in Bitcoin Core. The commit message explains the call was doing nothing useful because an earlier step already set the same state. There is n…
9249e608by marcofleon+0−21 fileThis change only affects how Bitcoin Core's internal fuzz tests create temporary working folders. When running under the AFL++ fuzzer, it now reuses a folder named after the fuzzer's shared-memory ID and deletes any leftover contents first…
d3e681bcby marcofleon+11−21 fileThis commit is a simple code cleanup: it takes a block of code that built a simplified tree-shaped dependency graph inside one fuzz test and moves it into a reusable helper function named BuildTreeGraph. The behavior is unchanged; no secur…
a70a14a3by marcofleon+40−291 fileThis is a one-line bug fix in a fuzz test (automated randomized test) for Bitcoin Core's transaction clustering logic. The test meant to check that running an optimization twice on a copy of a tree-shaped dependency graph produces the same…
ce29d7d6by marcofleon+2−21 fileThis commit fixes a bug in an internal Bitcoin Core fuzz test (a randomized self-test used during development). The test was looping over transaction indices using the total transaction count, but some indices can be unused 'holes' in the …
876e2849by marcofleon+2−21 fileThis commit only changes internal fuzz testing code. It reduces the number of loop iterations in three slow-running fuzz targets so the tests run faster. It does not touch any production Bitcoin Core code, network protocol, wallet, consens…
6a33970fby marcofleon+4−43 filesThis commit is a pure code reorganization: it moves a header file that defines transaction ID types (Txid, Wtxid) from one directory to another and updates all the places that include it. There are no functional changes to how Bitcoin Core…
de0675f9by marcofleon+113−11320 filesThis commit removes shortcuts that let a new transaction ID type be silently treated as the older uint256 type. It is a code-cleanup change that makes type mismatches produce compile-time errors rather than compile silently. There is no di…
6f068f65by marcofleon+0−121 fileThis is a code cleanup change that replaces generic 256-bit hash values with more specific transaction ID types (Txid and Wtxid) across many files. It does not change what the program computes or how it protects data; it only makes the typ…
9c24cda7by marcofleon+117−6925 filesThis commit is a straightforward code cleanup that swaps the generic uint256 type for the more specific Txid type in transaction-related policy code. It does not change behavior, fix a bug, or introduce a security vulnerability. It is pure…
d2ecd681by marcofleon+22−238 filesThis commit is a straightforward internal code cleanup in Bitcoin Core. It replaces the generic 256-bit hash type (uint256) with more specific transaction ID types (Txid and Wtxid) in the memory pool and related code. There is no change to…
