Merge Risk: 🔵 Low · up to This backport adds XOR-aware file streams, a benchmark, tests, and small maintenance updates. No serious correctness or availability problem was found, so it is mergeable. Two small robustness gaps remain for follow-up. The descriptor-wallet test can leave its database connection open if the insert fails. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.
Inline comments:
In `@src/streams.h`:
- Line 510: Update AutoFile::feof() to check m_file before calling std::feof,
returning false when the handle is null while preserving the existing behavior
for valid handles.
In `@test/functional/wallet_descriptor.py`:
- Line 201: Wrap the transaction using conn and its conn.execute call in a
try/finally block, moving conn.close() into finally so the database connection
closes on both successful and exceptional exits.

Final validation — Phase 2 only (queue backlog)
No actionable correctness defects or Dash-specific regressions were identified in the four-commit range. The stream implementation and build registration are consistent, and the wallet test changes match the existing scheduling and database-handling paths; the resolved discussion threads do not warrant renewed findings. Patch whitespace and Python syntax checks passed; full compilation and runtime test suites were not performed during this verification.
Review provenance
Source: reviewer 1: gpt-6-astra (agent: phase2-reviewer, role: general); reviewer 2: gpt-6-astra (agent: phase2-reviewer, role: backport-reviewer); reviewer 3: gpt-6-astra (agent: phase2-reviewer, role: dash-core-commit-history); final verifier: gpt-6-astra (agent: astra-verifier, role: final-verifier)
- Triage:
normalbygpt-6-astra(effort low) — The AutoFile refactor and optional position-aware XOR support in src/streams.h and src/streams.cpp warrant ordinary logic review, but do not introduce a storage migration or change consensus, cryptography, funds handling, or peer-facing deserialization; the remaining changes are minor modernization and test fixes. - Phase 1 reviewers: not run (skipped for throughput: 22 PRs queued, above the 10 limit)
- Fresh verifier:

This is needed for bitcoin#28052, but can also be used in any other place. Also, there are tests, so I've split this up from the larger pull to make review easier, hopefully.

…allettransactions.py e667bd6 test: fix intermittent failure in wallet_resendwallettransactions.py (Martin Zumsande) Pull request description: Fixes bitcoin#28094 The test bumps the mocktime for ~2 weeks and then triggers eviction from the mempool. But this bump will also cause a new resubmit, and if the timing is such that this resubmit happens right after the eviction and before the check that the tx was evicted, the test can fail as in bitcoin#28094: ``` node0 2023-07-17T21:31:23.809483Z (mocktime: 2023-08-02T09:46:27Z) [httpworker.1] [validation.cpp:267] [LimitMempoolSize] [mempool] Expired 2 transactions from the memory pool node0 2023-07-17T21:31:23.810079Z (mocktime: 2023-08-02T09:46:27Z) [scheduler] [wallet/wallet.h:895] [WalletLogPrintf] [default wallet] ResubmitWalletTransactions: resubmit 2 unconfirmed transactions node0 2023-07-17T21:31:23.810474Z (mocktime: 2023-08-02T09:46:27Z) [httpworker.2] [rpc/request.cpp:181] [parse] [rpc] ThreadRPCServer method=getmempoolentry user=__cookie__ 2023-07-17T21:31:23.811000Z TestFramework (ERROR): Assertion failed (...)

Backports 4 Bitcoin Core v0.26 pull request(s) that the Dash queue selected, including any discovered prerequisites: bitcoin#28060, bitcoin#28090, bitcoin#28108, bitcoin#28204.
What was done?

partial Merge …only where a hunk is deferred to a prerequisite still to be backported, named in the commit body; a hunk Dash intentionally never wants is recorded in the commit body or the reviewer's note above and does not make the backport partial). Conflicts were resolved commit by commit; commits that needed no resolution were cherry-picked unchanged.How Has This Been Tested?
Recorded per commit, at that commit's own sha, not once for the branch:
e850907174, which is this branch's headBreaking Changes
None beyond the upstream changes themselves.
Checklist:
Left for the reviewer; backportsys does not tick boxes on its own behalf.
Maintainer controls
Tick a box and backportsys acts on it within a few minutes, then clears the box. For anything else — a hunk to drop, a resolution to redo, a question — just leave a review comment; nothing here needs a box.
