	)

private

Prune block and undo files (blk???.dat and rev???.dat) so that the disk space used is less than a user-defined target.

The user sets the target (in MB) on the command line or in config file. This will be run on startup and whenever new space is allocated in a block or undo file, staying below the target. Changing back to unpruned requires a reindex (which in this case means the blockchain must be re-downloaded.)

Pruning functions are called from FlushStateToDisk when the m_check_for_pruning flag has been set. Block and undo files are deleted in lock-step (when blk00003.dat is deleted, so is rev00003.dat.) Pruning cannot take place until the longest chain is at least a certain length (CChainParams::nPruneAfterHeight). Pruning will never delete a block within a defined distance (currently 288) from the active chain's tip. The block index is updated by unsetting HAVE_DATA and HAVE_UNDO for any blocks that were stored in the deleted files. A db flag records the fact that at least some block files have been pruned.

Parameters

[out]	setFilesToPrune	The set of file indices that can be unlinked will be returned
	last_prune	The last height we're able to prune, according to the prune locks

◆ GUARDED_BY() [1/4]

std::array< std::optional< BlockfileCursor >, BlockfileType::NUM_TYPES > m_blockfile_cursors node::BlockManager::GUARDED_BY ( ::cs_main )

private

Since assumedvalid chainstates may be syncing a range of the chain that is very far away from the normal/background validation process, we should segment blockfiles for assumed chainstates.

Otherwise, we might have wildly different height ranges mixed into the same block files, which would impair our ability to prune effectively.

This data structure maintains separate blockfile number cursors for each BlockfileType. The ASSUMED state is initialized, when necessary, in FindNextBlockPos().

The first element is the NORMAL cursor, second is ASSUMED.

Calculate the amount of disk space the block & undo files currently use.

Check if all blocks in the [upper_block, lower_block] range have data available as defined by the status mask. The caller is responsible for ensuring that lower_block is an ancestor of upper_block (part of the same chain).

Returns the earliest block with specified status_mask flags set after the latest block not having those flags.

This function starts from upper_block, which must have all status_mask flags set, and iterates backwards through its ancestors. It continues as long as each block has all status_mask flags set, until reaching the oldest ancestor or lower_block.

Precondition: upper_block must have all status_mask flags set.; lower_block must be null or an ancestor of upper_block

Parameters

upper_block	The starting block for the search, which must have all `status_mask` flags set.
status_mask	Bitmask specifying required status flags.
lower_block	The earliest possible block to return. If null, the search can extend to the genesis block.

Returns: A reference to the earliest block between upper_block and lower_block, inclusive, such that every block between the returned block and upper_block has status_mask flags set. True if any block files have ever been pruned.

The height of the base block of an assumeutxo snapshot, if one is in use.

This controls how blockfiles are segmented by chainstate type to avoid comingling different height regions of the chain when an assumedvalid chainstate is in use. If heights are drastically different in the same blockfile, pruning suffers.

This is set during ActivateSnapshot() or upon LoadBlockIndex() if a snapshot had been previously loaded. After the snapshot is validated, this is unset to restore normal LoadBlockIndex behavior.
