WalkthroughThe wallet API no longer passes a CoinJoin loader or an ArgsManager to CWallet. The chain interface now provides CoinJoin loader access, and wallet registration and flushing use that access point. Wallet and script managers store and use the configured keypool size. Wallet constructors, loader creation, benchmarks, tools, and tests are updated. The Qt options model adds hasSigner(), which the send dialog uses to check whether the signer option is set. Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Wallets created with a separate argument manager can silently ignore the requested mnemonic length and the wallet-backup setting on unlock. Cache these settings from the creation arguments before merging. Pre-merge checks |

Read wallet settings from the wallet’s configured argument manager.
If context.args differs from gArgs, this line ignores its -mnemonicbits setting when creating a descriptor wallet. A wallet that requests a specific mnemonic length can receive a different one. Line 4212 has the same root cause for -createwalletbackups after unlock. Cache both settings from context.args in CWallet::Create, then use the cached values in these paths. The supplied test contexts demonstrate that separate argument managers are supported.

Final validation — Phase 1 + Phase 2
Verified two Dash-specific regressions at head 6679c05: CoinJoin registration can happen after GUI initialization requires it, and descriptor mnemonic generation ignores the wallet context's entropy setting. The commit-label nitpick is also supported; the backup-setting finding is dropped because backup retention is already process-wide. This was static verification only: the supplied CI snapshot shows successful lint and several platform builds, while multiple Linux builds and wallet-enabled tests remain pending.

- [BLOCKING] src/wallet/wallet.cpp:134-135: Complete CoinJoin registration before notifying wallet-loaded observers
CoinJoin registration now happens only in AddWallet, but LoadWalletInternal, CreateWallet, and LoadWallets invoke NotifyWalletLoaded first. The GUI observer emits walletAdded, whose handler constructs a WalletView and calls OverviewPage::setWalletModel. That initialization makes a one-time WithClient call to disable the client's built-in automatic backups. The walletAdded connection uses Qt::AutoConnection, so during a runtime wallet load the GUI can process it before the loading thread reaches AddWallet. With no registered client, WithClient returns false and skips the callback; the client subsequently created by AddWallet retains fCreateAutoBackups=true. For a legacy wallet, the CoinJoin worker can then perform backups that the GUI is supposed to manage along with user warnings. Previously CWallet::Create registered the client before these observers ran, and the later try_emplace did not replace that client. Keep registration single-shot, but complete it before wallet-loaded observers can initialize the GUI.
- [BLOCKING] src/wallet/wallet.cpp:4411: Preserve the wallet context's mnemonic entropy setting
Replacing m_args with gArgs changes which configuration controls descriptor mnemonic generation. CWallet::Create still accepts context.args and caches keypool and notification settings from that manager, and the test fixtures supply independent ArgsManager instances. If context.args requests -mnemonicbits=256 while gArgs has its default, this path now generates a 128-bit, 12-word mnemonic rather than the requested 256-bit, 24-word mnemonic. Before this PR, the wallet retained context.args and honored its setting here. Cache mnemonic entropy from context.args during CWallet::Create and use that value in this function, so both immediate initialization and later initialization of encrypted or blank descriptor wallets preserve the configured entropy.

Good catch, fixed by calling AddWallet before NotifyWalletLoaded in LoadWalletInternal, CreateWallet and LoadWallets.

Resolved (re-reviewed at 6f39d88d): Verified your ordering correction in LoadWalletInternal, CreateWallet, and LoadWallets: AddWallet now completes CoinJoin registration before NotifyWalletLoaded invokes observers. The GUI's initialization callback can therefore find the client and disable its built-in automatic backups.

Done: -mnemonicbits is now cached in CWallet::Create from context.args, next to m_keypool_size and the notify scripts, and SetupDescriptorScriptPubKeyMans uses the cached value.
dash-wallet never registers -mnemonicbits, so the default there is unchanged. -createwalletbackups stays on gArgs: it seeds the process-global nWalletBackups together with CWallet::InitAutoBackup, so a per-wallet copy would let two wallets reset one shared global to different values.

Resolved (re-reviewed at 6f39d88d): Verified that you cache -mnemonicbits from context.args before wallet initialization and use m_mnemonic_bits for descriptor mnemonic generation, including deferred initialization. Your explanation for retaining -createwalletbackups on gArgs also matches InitAutoBackup's existing initialization of the process-global nWalletBackups.

CWallet::Create registered twice the freshly loaded wallet: with the CoinJoin client manager and AddWallet registered it again. Though RemoveWallet un-rester it only once and it causes the client manager holds a shared_ptr to the wallet permanently. That is why TestLoadWallet had to force an AddWallet call, and why bench/wallet_loading only works as long as its WalletContext carries no loader. CoinJoin registration now happens only in AddWallet, but LoadWalletInternal, CreateWallet, and LoadWallets invoke NotifyWalletLoaded first. The GUI observer emits walletAdded, whose handler constructs a WalletView and calls OverviewPage::setWalletModel. That initialization makes a one-time WithClient call to disable the client's built-in automatic backups So, order or NotifyWalletLoaded should be re-ordered with AddWallet
AddWallet, RemoveWallet and FlushWallets are the only consumers for wallet->coinjoin_loader() therefore it is passes as a constructor argument over ~40 instanses all over code base [including regressions tests], often as nullptr because it's irrelevant and wallet never user it. The wallet reaches every other node service through interfaces::Chain, but the CoinJoin loader is diffferent. NodeContext owns it and it goes through MakeWalletLoader by reference Having it as part of Chain's interface provide the loader to wallet always when it's available. The nullptr here means the node has no cj: -disablewallet or BasicTestingSetup. Take it from the wallet's chain instead. In this case it will never be forgotten [as nullptr by mistake] and removed diversity with original upstream bitcoin core
CWallet stored an interfaces::CoinJoin::Loader but the only readers are AddWallet/RemoveWallet/FlushWallets which uses wallet's chain interface. Threading it through the constructor made almost 100 diverge hunks with upstream, half of them passing /*coinjoin_loader=*/nullptr. It helps also to remove include interfaces/coinjoin.h from wallet.h and related members.
WalletContext::coinjoin_loader is not read by any function anymore. Remove the field, the unused arguments in Init::makeWalletLoader and related cleanups No more multiple context.coinjoin_loader all over codebase

So this PR migrates the only two places where we depend on it: (1) the keypool size, and (2) the "-walletnotify" script. And cleans up the, now unneeded, wallet `ArgsManager` ref member.

Re-review — Final validation — Phase 1 + Phase 2
Static verification of the complete range at 6f39d88 confirms that both prior functional regressions are fixed, with no additional production-code defect identified. One inherited upstream test-hunk omission remains undocumented under the advertised full-PR backport and needs an explicit exclusion statement. No local builds or tests were run; current CI shows passing lint, multiple platform builds, and Linux wallet, no-wallet, and SQLite tests, while ASan and multiprocess builds and TSan tests remain pending.

- [BLOCKING] src/wallet/test/ismine_tests.cpp:359-361: Document the inherited omission of the Taproot test hunk
The PR advertises Bitcoin Core #26889 without identifying an excluded upstream area. That upstream merge changes the CWallet constructor in the `Taproot - Descriptor` scenario of `ismine_standard` at upstream line 645, but Dash's base and head both proceed directly from `Combo - Descriptor` to `OP_RETURN`. The scenario originated in upstream #25942, commit 1b77db265317a6470d0914b520f04eb64b3c0942; Dash's corresponding backport bdf77f2a73975a8a7b0130d5df299f2efbfd28c2 is already an ancestor of this PR's base and omitted it. This is an inherited omission, not a test deleted by this PR or a runtime failure in the constructor refactor. Nevertheless, the advertised full backport leaves this upstream hunk unaccounted for, and the PR description and backport commit message contain no explicit exclusion. Document that the Taproot descriptor test adaptation is intentionally excluded because Dash's Taproot adoption is deferred. Introducing Taproot or redoing the entire earlier backport is not required.

This hunk for taproot will cause compilation error -> it means there's no need to do special mark as partial, but when taproot's code will be added - it will be immediately added in the correct form.
26889 is full, not partial
There was a problem hiding this comment.
You're right; I overstated this as a blocking omission. The upstream scenario uses XOnlyPubKey, TaprootBuilder, and WitnessV1Taproot, which are absent here, and it was already excluded in Dash's bitcoin#25942 backport. bitcoin#26889 only updates the constructor call in that nonexistent scenario; it doesn't introduce Taproot coverage or leave an existing Dash call unconverted. I withdraw the request to label this backport partial or add a special exclusion note.

Cherry-picked (`git cherry-pick -m1 -x`) every develop merge since rc.3 that carries `backport-candidate-24.0.x`, plus eight unlabeled fixes picked after an audit of every other develop merge since rc.3 (marked † below). They are in develop merge order: - #7814 fix(qt): restore HTML escaping of send confirmation recipients † - #7851 fix(rpc): correct masternode status help for top-level service field - #7816 fix: check credit pool amount accumulation - #7828 fix: omit recovery words from invalid mnemonic errors † - #7822 fix: reject malformed detached quorum share batches † - #7810 fix(rpc): handle unavailable masternode payment inputs † - #7838 fix(wallet): authenticate unlock deadline extensions - #7792 fix: treat missing snapshots during evodb repair as repair errors - #7821 fix: relock encrypted wallets after HD upgrade failures - #7834 fix: validate Electrum import input boundaries - #7818 fix: return REST errors for unavailable deployment data - #7829 fix: preserve wallet permissions when changing passphrases - #7820 fix: hold chainstate lock during CoinJoin input validation - #7841 fix: authenticate cached InstantSend proof bytes - #7831 fix: bound governance object signatures and reset the governance cache - #7521 fix: update masternode rate limit on failed governance trigger path - #7866 fix: stop `masternode payments` at the genesis block - #7867 fix: refuse masternode list RPCs for blocks outside the active chain † - #7871 backport!: bitcoin#27217: wallet: Replace use of purpose strings with an enum - #7876 fix(consensus): capture operator key scheme changes with unchanged bytes in state diffs - #7875 docs(rpc): clarify getchainlockbyheight availability † - #7839 fix: release InstantSend tracking after mempool eviction - #7827 backport: partial bitcoin#35984 - #7824 fix: retain initialized DKG sessions during inventory reads - #7836 backport: partial bitcoin#25812, bitcoin#29855 - #7782 fix(wallet): persist pending-observation coin locks once the record becomes readable - #7881 fix: refuse to sign shared registrar updates that move the funder's coins † - #7858 fix: do not InstantSend-lock provider transactions - #7817 backport: partial bitcoin#34156 restore cleanup ownership - #7894 test: fix feature_pruning.py restart arguments † (needed because #7792 makes the evodb repair fatal, which the old restart arguments trip) - #7893 fix(net): announce sporks to new peers instead of requesting them during mnsync - 4a19742 (from #7859) test: follow-up for #7821: check if wallet is locked after failed upgrade instead creating brand-new scenario. Test-only, picked as its commit. Without it, #7821's `test_failed_upgrade()` expects RPC error -1 for a 257-byte mnemonic passphrase, which #7842's new precheck rejects with -8 first, so `wallet_upgradetohd.py --legacy-wallet` fails. On develop, #7859 replaced that scenario before #7842 merged. The rest of #7859 is test cleanup and docs and is left out. - #7842 fix(wallet): reject mnemonic passphrases that seed derivation truncates - #7857 fix: mine a pending ProUpServTx before a key change of its masternode - #7846 fix: treat pending owner keys and Platform node IDs as one conflict namespace - #7895 test: cover retroactive provider tx refusal, fix wording - #7909 feat(mining): build the masternode list incrementally during block assembly - #7537 fix: data races and check-then-act races in the CoinJoin server - #7888 fix(consensus): canonical ExtNetInfo encoding and strict netInfo decoding 34 of the 39 picks change exactly the same lines as their develop merges. #7888 and #7782 needed test-only changes (see testing), and three others needed adaptation, described in their commit messages: - **#7893** was merged to develop twice: f99212b with an earlier revision of its commit, then 72a5997 with the final one, so develop now announces sporks twice in the VERACK handler (a develop fix is open separately). Here the PR's final commit 45acdf3 is picked once instead of either merge. In `src/node/sync_manager.cpp`, this branch still sent `GETSPORKS` from the mnsync tick on every network, because #7847, which limited it to test chains, is not included. The request is removed entirely, as on develop. Mainnet spork values are hardcoded in `CSporkManager::GetSporkValue`, so the mainnet request had no effect. - **#7857** and **#7909**: develop folded `CChainstateHelper` into `Chainstate` (d5c1bd7), which is not on this branch, so the new code goes through `ChainHelper().special_tx` / `m_chain_helper.special_tx` instead of `m_special_tx`. The neighbouring develop-only `CSpecialTxProcessor::GetDeterministicMNListHash` is left out. #7888 tightens consensus rules for ExtAddr provider transactions behind V24, so I checked it against testnet. V24 is not active there yet (the tip's CbTx is still version 3), so the chain has no ExtAddr ProTxs the new rules could reject. rc.3's own serializer always writes canonical, sorted purposes, so every ProTx it builds passes the new rules. Mixed rc.3/rc.4 networks could only split on a hand-crafted non-canonical ExtAddr ProTx mined after V24 activates. So testnet miners and masternodes should move to rc.4 before V24 is signalled. Unlabeled develop fixes since rc.3 that were audited and left out: - Worth considering before the final release: #7869 (startup block replay after an unclean shutdown asserts on a quorum commitment, so recovery needs `-reindex-chainstate`; not a v24 regression), #7833 (gate signing intake before quorum retrieval, DoS hardening), #7682 (intermittent `relic_conf.h` parallel-build failure). - Left for 24.1: #7812, #7826, #7844, #7847, #7850, #7868, plus the routine upstream backports (#7780, #7806, #7830, #7855, #7856, #7862, #7863, #7865, #7883, #7884, #7898, #7906), refactors (#7805, #7878, #7880), and CI, docs and test-only changes. One CI-only commit comes last. It takes only the `ci/test` hunks of 6f71fa5 (#7901), which make `ci/test/00_setup_env_native_{multiprocess,tsan}.sh` honor `DEPENDS_ARCH`. Pull requests into `v24.0.x` run develop's workflow files (`pull_request_target`), and since #7901 those check the depends cache on x86_64 runners and pass the aarch64 build arch in `DEPENDS_ARCH`. Without the hunks, `linux64_multiprocess / Build depends` fails on any depends cache miss (`Build runner computes HOST=aarch64-linux-gnu but check-cache used x86_64-pc-linux-gnu`). Without `DEPENDS_ARCH` the scripts still use `uname -m`, so this branch's own push CI is unchanged. No version change is needed. `configure.ac` is already 24.0.0 with `CLIENT_VERSION_IS_RELEASE` false, so the build takes its version string from the `v24.0.0-rc.4` tag. ## How Has This Been Tested? Built and tested at 6c02b2b on macOS arm64 against depends, with `--enable-debug --enable-werror --disable-hardening`. - `make check`: all unit test suites pass, including `test_dash-qt`. - Functional tests, all passing: `feature_evo_shares_activation.py`, `feature_governance_objects.py`, `feature_llmq_signing.py` (plain and `--spork21`), `feature_masternode_shares.py`, `feature_sporks.py`, `interface_rest.py`, `p2p_instantsend.py`, `p2p_quorum_data.py`, `rpc_masternode.py`, `rpc_psbt.py`, `rpc_quorum.py`, `wallet_backup.py`, `wallet_dump.py`, `wallet_encryption.py`, `wallet_labels.py` and `wallet_upgradetohd.py`, each with `--descriptors` and `--legacy-wallet` where it supports them. - Each pick's changed lines were compared with its develop merge (or, for #7893, its PR commit). They are identical except for the #7893, #7857 and #7909 adaptations above, and the #7888 test adaptation below. - A local macOS arm64 debug build (`--enable-debug --enable-werror`) compiled most of the tree and stopped on a single error in `src/test/evo_netinfo_tests.cpp`. #7888's new test used `CNetAddr::V2()`, the serialization-parameter API from bitcoin#25284, which this branch lacks. The pick now writes that entry through an `OverrideStream` with `ADDRV2_FORMAT`, the way `NetInfoEntry::Serialize` does on this branch (see its commit message). - #7782's new unit test reloads the wallet with develop's three-argument `CWallet` constructor. On this branch the constructor still takes the CoinJoin loader and an `ArgsManager`, so the test passes them the way its fixture already does (see the commit message). - With both test fixes, a full local `make` (`dashd`, `dash-qt`, `test_dash`, `test_dash-qt`) completes with no errors. - `feature_pruning.py` is an extended test that CI does not run. #7894 is included because #7792 makes its restart path fail. ## Breaking Changes Carried over from the picked PRs: - #7876: rc.1 to rc.3 nodes that connected an affected block stored a wrong masternode list diff for it. Those nodes need `-reindex`; `-reindex-chainstate` is not enough for nodes that already marked the following block invalid. - #7888: stricter ExtAddr `netInfo` decoding and validation behind V24 (see above). The RFC1918 check now applies even with `-allowprivatenet`. - #7858: provider transactions no longer get InstantSend locks. Software that waits for an islock on a ProTx should wait for a ChainLock or confirmations instead. - #7857: a `ProUpServTx` spending an output of a pending operator key change, asset lock, asset unlock or MNHF signal is rejected from the mempool until that transaction confirms. - #7831: governance object signatures over 96 bytes are rejected, and the governance cache is discarded and re-synced on first start (`doc/release-notes-7831.md`). - #7871: address purposes are limited to `send`, `receive` and `refund`. Wallets with other purpose strings load with warnings, and `listlabels` errors on an unknown purpose (`doc/release-notes-27217.md`). - #7842: creating an HD wallet with a mnemonic passphrase over 248 bytes fails unless `-allow-deprecated-long-mnemonics` is set, and over 256 bytes always fails (`doc/release-notes-7842.md`). - #7792: a node whose evodb is missing a masternode list snapshot now stops at startup and asks for `-reindex`, and `evodb repair` reports it in `repairErrors`. - #7867: `protx info <proTxHash> <blockHash>`, `protx listdiff` and `masternode payments <blockHash>` return an error for blocks outside the active chain. - #7881: `protx shared_combine` on a `ProUpSharedRegTx` is refused unless its inputs are unlocked coins of a single address of the calling wallet, change returns to that address, and the fee is within `-maxtxfee`. - #7836: PSBTs referencing nonexistent previous outputs fail to deserialize (RPC error -22). - #7834: negative Electrum-import rescan indices are rejected. - #7893: on this branch, mainnet nodes no longer send `GETSPORKS` during mnsync (no effect, mainnet spork values are hardcoded). ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

Issue being fixed or feature implemented
CWallet has extra argument coinjoin_loader in its ctor and it makes pain when doing backports due to more than 100 usages spread all over code bases and it causes conflicts when doing backport.
What was done?
Backport bitcoin#26889 is touching every line what had caused conflicts due to extra argument in CWallet constructor, this PR has all important prerequisites to make its merge easier.
NOTE: some chunks of 26889 is omitted because this code is not backported yet [including taproot's related], some other quite opposite added. Though, 26889 is not partial and done in full because compiler enforces missing changes to update: remove gArgs / m_args if they will be added later by other commits.
How Has This Been Tested?
Run unit & regressions tests.
