2024-05-30build: remove --enable-lcov-branch-coveragefanquake
This supports lcov 2.x in the sense that we are no-longer hardcoding version specific options, and instead will use the `LCOV_OPTS` variable (which is the more correct/flexible thing to do in any case). It's also quite likely that devs are already having to pass extra options to lcov 2.x, given it's more stringent in terms of coverage generation and error checking. See this thread for an example: https://github.com/linux-test-project/lcov/issues/238. Added an example to the developer notes. Tested on one machine (LCOV 2.0, gcc 13.2) with: ```bash ./autogen.sh ./configure --enable-lcov CXXFLAGS="-fprofile-update=prefer-atomic" LCOV_OPTS="--rc branch_coverage=1 --ignore-errors mismatch" make make cov <snip> Processing file src/netaddress.cpp lines=521 hit=480 functions=72 hit=72 branches=675 hit=499 Overall coverage rate: lines......: 81.8% (79362 of 97002 lines) functions......: 77.8% (10356 of 13310 functions) branches......: 49.6% (130628 of 263196 branches) ``` and another machine (LCOV 2.1, Clang 18.1.3) with: ```bash ./autogen.sh ./configure --enable-lcov CC=clang CXX=clang++ LCOV_OPTS="--rc branch_coverage=1 --ignore-errors mismatch,inconsistent" make make cov <snip> Processing file src/util/strencodings.cpp lines=315 hit=311 functions=38 hit=38 branches=425 hit=357 Overall coverage rate: source files: 622 lines.......: 79.8% (70311 of 88132 lines) functions...: 78.1% (13968 of 17881 functions) branches....: 44.5% (157551 of 354317 branches) Message summary: 101 warning messages: count: 1 inconsistent: 100 3528 ignore messages: inconsistent: 3528 ```

Android-related stuff 5deb0b024e14c7c63d405c651d1ca323560a1c21 build, test, doc: Temporarily remove Android-related stuff (Hennadii Stepanov) Pull request description: Previously, our Android builds were geared towards generating APKs, which relied on Qt. However, after migrating to C++20, compiling for Android became unfeasible due to Qt 5.15's compatibility limitations with NDK only up to r25, which includes an outdated embedded libc++ (see https://github.com/bitcoin/bitcoin/issues/29360). All removed stuff will be reinstated after migrating the build system to CMake and upgrading Qt to version 6.x. This PR makes possible a clean migration to the CMake-based build system as it removes code, which is not used at this moment.

2024-05-29refactor: use recommended type hiding on multi_index typesCory Fields
Recommended by boost docs: https://www.boost.org/doc/libs/1_85_0/libs/multi_index/doc/compiler_specifics.html#type_hiding This significantly reduces the size of the symbol name lengths that end up in the binaries as well as in compiler warnings/errors.

Since the wallet is appended to the global `WalletContext` during creation, merely calling `reset()` on the benchmark shared_pointer is insufficient to destruct the wallet. This no destruction of the wallet object results in keeping the db connection open, which was causes the `fs::remove_all()` failure on Windows.

2024-05-24Fold GetSelectionWaste() into ComputeAndSetWaste()Murch
Both `GetSelectionWaste()` and `ComputeAndSetWaste()` now are part of `SelectionResult`. Instead of `ComputeAndSetWaste()` being a wrapper for `GetSelectionWaste()`, we combine them to a new function `RecalculateWaste()`. As I was combining the logic of the two functions, I noticed that `GetSelectionWaste()` was making the odd assumption that the `change_cost` being set to zero means that no change is created. However, if we build transactions at a feerate of zero with the `discard_feerate` also set to zero, we'd organically have a `change_cost` of zero, even when we create change on a transaction. This commit cleans up this duplicate meaning of `change_cost` and relies on `GetChange()` to figure out whether there is change on basis of the `min_viable_change` and whatever is left after deducting fees. Since this broke a bunch of tests that relied on the double-meaning of `change_cost` a bunch of tests had to be fixed.

For single transaction acceptance, this is a simple refactor: Workspace::m_all_conflicting Workspace::m_conflicting_fees Workspace::m_conflicting_size Workspace::m_replaced_transactions are now grouped under a new SubPackageState struct that is a member of MemPoolAccept. And local variables m_total_vsize and m_total_modified_fees are now SubpackageState members so they can be accessed from PackageMempoolChecks. We want these to be package-wide variables because - Transactions could conflict with the same tx (just not the same prevout), or their conflicts could share descendants. - We want to compare conflicts with the package fee rather than individual transaction fee. We reset these MemPoolAccept-wide fields for each subpackage evaluation to not cause state leaking, similar to temporary coins.

The behavior is not new, but this rule exits earlier than before. Previously, a carve out could have been granted in PreChecks() but then nullified in PackageMempoolChecks() when CheckPackageLimits() is called with the default limits.

We like the idea of a smaller maximum transaction size because: - It lowers potential replacement cost (i.e. harder to do Rule 3 pinning via gigantic transaction) - They are easier to bin-pack in block template production - They equate to a tighter memory limit in data structures that are bounded by a number of transactions (e.g. orphanage and vExtraTxnForCompact). For example, the current memory bounds for orphanage is 100KvB * 100 = 40MB, and guaranteeing 1 tx per peer would require reserving a pretty large space. History for `MAX_STANDARD_TX_WEIGHT=100KvB` (copied from https://github.com/bitcoin/bitcoin/pull/29873#issuecomment-2115459510): - 2010-09-13 In https://github.com/bitcoin/bitcoin/commit/3df62878c3cece15a8921fbbdee7859ee9368768 satoshi added a 100kB (MAX_BLOCK_SIZE_GEN/5 with MBS_GEN = MAX_BLOCK_SIZE/2) limit on new transactions in CreateTransaction() - 2013-02-04 https://github.com/bitcoin/bitcoin/pull/2273 In gavin gave that constant a name, and made it apply to transaction relay as well Lowering `MAX_STANDARD_TX_WEIGHT` for all txns is not being proposed, as there are existing apps/protocols that rely on large transactions. However, it's been brought up that we should consider this for TRUCs (which is especially designed to avoid Rule 3 pinning). This reduction should be ok because using nVersion=3 isn't standard yet, so this wouldn't break somebody's existing use case. If we find that this is too small, we can always increase it later. Decreasing would be much more difficult. ~[Expected size of a commitment transaction](https://github.com/lightning/bolts/blob/master/03-transactions.md#expected-weight-of-the-commitment-transaction) is within (900 + 172 * 483 + 224) / 4 = 21050vB~ EDIT: this is incorrect, but perhaps not something that should affect how we choose this number.

d7707d9843b03f20d2a8c5a45d7b3db58e169e6f rpc: avoid copying into UniValue (Cory Fields) Pull request description: These are the simple (and hopefully obviously correct) copies that can be moves instead. This is a follow-up from https://github.com/bitcoin/bitcoin/pull/30094#issuecomment-2108751842 As it turns out, there are hundreds of places where we copy UniValues needlessly. It should be the case that moves are always preferred over copies, so there should be no downside to these changes. willcl-ark, however, noticed that memory usage may increase in some cases. Logically this makes no sense to me. The only plausible explanation imo is that because the moves are faster, more ops/second occur in some cases. This list of moves was obtained by changing the function signatures of the UniValue functions to accept only rvalues, then compiling and fixing them up one by one. There still exist many places where copies are being made. These can/should be fixed up, but weren't done here for the sake of doing the easy ones first. I ran these changes through clang-tidy with `performance-move-const-arg` and `bugprone-use-after-move` and no bugs were detected (though that's obviously not to say it can be trusted 100%). As stated above, there are still lots of other less trivial fixups to do after these including: - Using non-const UniValues where possible so that moves can happen - Refactoring code in order to be able to move a UniValue without introducing a use-after-move - Refactoring functions to accept UniValues by value rather than by const reference ACKs for top commit: achow101: ACK d7707d9843b03f20d2a8c5a45d7b3db58e169e6f ryanofsky: Code review ACK d7707d9843b03f20d2a8c5a45d7b3db58e169e6f.

6629d1d0f8285d1bf2d87341a856abe903f26c13 test: improve robustness of connect_nodes() (furszy) Pull request description: Decoupled from #27837 because this can help other too, found it investigating a CI failure https://cirrus-ci.com/task/5805115213348864?logs=ci#L3200. The `connect_nodes` function in the test framework relies on a stable number of peer connections to verify that the new connection between the nodes is successfully established. This approach is fragile, as any of the peers involved in the process can drop, lose, or create a connection at any step, causing subsequent `wait_until` checks to stall indefinitely even when the peers in question were connected successfully. This commit improves the situation by using the nodes' subversion and the connection direction (inbound/outbound) to identify the exact peer connection and perform the checks exclusively on it.
