Available log space is divided up in blocks of +// CENSUS_LOG_2_MAX_RECORD_SIZE bytes. A block can be in one of the following +// three data structures: +// - Free blocks (free_block_list) +// - Blocks with unread data (dirty_block_list) +// - Blocks currently attached to cores (core_local_blocks[]) +// +// census_log_start_write() moves a block from core_local_blocks[] to the end of +// dirty_block_list when block: +// - is out-of-space OR +// - has an incomplete record (an incomplete record occurs when a thread calls +// census_log_start_write() and is context-switched before calling +// census_log_end_write() +// So, blocks in dirty_block_list are ordered, from oldest to newest, by the +// time when block is detached from the core. +// +// census_log_read_next() first iterates over dirty_block_list and then +// core_local_blocks[]. It moves completely read blocks from dirty_block_list +// to free_block_list. Blocks in core_local_blocks[] are not freed, even when +// completely read. +// +// If the log is configured to discard old records and free_block_list is empty, +// census_log_start_write() iterates over dirty_block_list to allocate a +// new block. It moves the oldest available block (no pending read/write) to +// core_local_blocks[]. +// +// core_local_block_struct is used to implement a map from core id to the block +// associated with that core. This mapping is advisory. It is possible that the +// block returned by this mapping is no longer associated with that core. This +// mapping is updated, lazily, by census_log_start_write(). +// +// Locking in block struct: +// +// Exclusive g_log.lock must be held before calling any functions operating on +// block structs except census_log_start_write() and census_log_end_write(). +// +// Writes to a block are serialized via writer_lock. census_log_start_write() +// acquires this lock and census_log_end_write() releases it. On failure to +// acquire the lock, writer allocates a new block for the current core and +// updates core_local_block accordingly. +// +// Simultaneous read and write access is allowed. Readers can safely read up to +// committed bytes (bytes_committed). +// +// reader_lock protects the block, currently being read, from getting recycled. +// start_read() acquires reader_lock and end_read() releases the lock. +// +// Read/write access to a block is disabled via try_disable_access(). It returns +// with both writer_lock and reader_lock held. These locks are subsequently +// released by enable_access() to enable access to the block. +// +// A note on naming: Most function/struct names are prepended by cl_ +// (shorthand for census_log).
