chainparams: add overloads for RegTest and SigNet with no options

This commit is a small internal code cleanup for Bitcoin Core. It adds shortcut versions of two functions used only for test networks (RegTest and SigNet) so callers don't have to pass an empty options object. There is no user-facing chang…

chainparams: make deployment configuration available on all test networks

This commit lets Bitcoin Core accept two testing-only command-line options on test networks (testnet, testnet4, signet) instead of only on regtest. It also adds an explicit guard so those options cannot be used on the real mainnet. The cha…

Deployment parameter options expanded from regtest-only to all test networksNew mainnet guard explicitly prevents -testactivationheight and -vbparams on mainnetHelp text changed from 'regtest-only' to 'test-only'

chainparams: encapsulate deployment configuration logic

This commit is a straightforward internal code reorganization. It moves the logic that applies custom soft-fork activation settings from one place in the code to another, grouping it into a reusable helper function. There is no change to h…

validation: correct lifetime of precomputed tx data

This commit fixes a memory safety bug in Bitcoin Core's block validation. When checking a new block, the program creates a queue of script checks that may run on multiple threads in the background. It also precomputes some transaction data…

doc: update release process to mention security advisories pre-announcements

This commit only changes documentation. It updates Bitcoin Core's release notes template and release process checklist to remind maintainers to mention upcoming security advisories when announcing a new release. No code, no bug fix, no vul…

Add release note for #33050 and #33183 error string changes

This commit only adds a release note describing a previous change to error message wording in Bitcoin Core. It does not change any code, behavior, or security properties. The error strings were renamed from 'mandatory/non-mandatory-script-…

contrib: adapt max reject string size in tracing demo

This is a trivial comment and constant update in a tracing demonstration script. It changes a documented maximum string length from 118 to 114 characters because a previous commit shortened the longest possible rejection reason. There is n…

scripted-diff: validation: rename mandatory errors into block errors

This commit is a simple automated rename of user-facing error messages and test expectations. It changes the phrase 'mandatory-script-verify-flag-failed' to 'block-script-verify-flag-failed' across source code and tests. No validation logi…

policy: introduce a helper to detect whether a transaction spends Segwit outputs

This commit adds a new internal helper function in Bitcoin Core that detects whether a transaction spends any Segregated Witness (Segwit) output, except for a special 'anchor' output type. It does not change network rules, user-visible beh…

validation: detect witness stripping without re-running Script checks

This commit changes how Bitcoin Core detects when a transaction's witness data has been stripped away. Previously, the software ran expensive script checks up to three times to figure out if a transaction failed only because its witness wa…
