chore: drop legacy CDeterministicMNState formats, evodb upgrade logic
#6579
Conversation
Co-authored-by: UdjinM6 <[email protected]>
WalkthroughThe pull request removes legacy support for migrating EvoDb databases and handling outdated formats within the deterministic masternode management code. The documentation has been updated to advise users upgrading from versions 19 and 20 to reindex their databases. In the code, functions and logic related to migrating or reading from older EvoDB formats have been eliminated. Specifically, migration methods in the deterministic masternode manager and compatibility constructors for legacy masternode states were removed, as well as constants and enumeration values related to older formats and upgrade errors. Modifications in the chainstate loading process also remove specific calls and error handling for EvoDb migrations, thereby streamlining the overall initialization, serialization, and state management processes.

76-79: Consider providing more user guidance in the exception message.
Although throwing an exception is correct for dropping older formats, you might include additional steps or references within this message (e.g., pointing users to release notes) to help them troubleshoot reindex requirements more easily.

84-84: No further concerns on thepdmnStatefield.
READWRITE forpdmnStateis consistent with dropping old states and uses the updated format logic correctly.
88-88: Good approach for handling type properly based on version.
The version check ensures backward compatibility for older network peers by defaulting toMnType::Regular.
214-214: Logic looks good for deserializing and adding masternodes.
Creation ofCDeterministicMNinstances using the new format version is aligned with the removal of old formats.

It has therefore been included. * `EraseOldDBData()` fell into disuse after [dash#6579](#6579) but wasn't removed then. It has been removed now due to `-Wunused-function` enforcement. * An extraneous `ApplyStats()` definition was left over when backporting [bitcoin#19145](bitcoin#19145). It has been removed now due to `-Wunused-function` enforcement. * [bitcoin#25337](bitcoin#25337) ([commit](a7d4127)) did not include a lock annotation for the lambda expression in `ListReceived()`. It has been added alongside `AssertLockHeld`s for both the lambda expression and the function. This was done to pass `-Wthread-safety` enforcement. * `ParsePubKeyIDFromAddress()`, `ParseBLSPubKey()` and `ValidatePlatformPort()` have been moved inside the `ENABLE_WALLET` macro conditional to avoid `-Wunused-function` warnings if building with wallets disabled. * Some dead code cannot be removed because they are either part of partial backports that may be completed in the future or complicate backports in the future that may expect their presence. To keep `-Wunused-function` happy, they have been marked with `[[maybe_unused]]` and this annotation should be removed when they are used. ## Breaking Changes None expected. ## Checklist - [x] I have performed a self-review of my own code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have added or updated relevant unit/integration/functional/e2e tests **(note: N/A)** - [x] I have made corresponding changes to the documentation **(note: N/A)** - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ ACKs for top commit: UdjinM6: utACK c7748cd PastaPastaPasta: utACK c7748cd Tree-SHA512: 5d746773a1f49c33f373250ba459a5da4301fea0cb5202d26717808d8a4985920cbdfec0903ed884f20561f8d40082b4ea796e78912bacff00e0645d355ec9f2
Additional Information
CDeterministicMNState_{Oldformat,mntype_format} was introduced in dash#5039 and dash#5403, included in Dash Core v19 and v20 respectively.The above change has been in the codebase for more than two major releases and does not concern databases with a long shelf life (like wallets), this pull request removes them entirely.
