1.3.11

• We have at least 3 different functions to write inodes
• PGO + Bolt instructions, build system
• Copy file
• test_tx_check_read_only
• test_tx_copy_file
• test_tx_copy_file_error_meta
• test_tx_copy_file_error_normal
• example_tx_copy_file

General

• Logging capabilities
• Replace NodeW.inodes with BTreeMap because woof - it does not scale. (Note: Shared CodSlice key with RefCell)
• Power failure testing
• Write failure testing (especially freelist reloading)

Open Questions

• Why do we need so much memory on large commits? Almost 3x the Go version
• Can we squeeze performance by moving the leaf keys all next to each other?

To Refactor

src/tx.rs

• Move tx stats in db.allocate to tx.allocate

src/nodes.rs

• Rebalance could be a lot better

src/db.rs

• Rework page size determination functions

src/bucket.rs

• Centralize memory aligned bump allocation (BucketIApi.open_bucket)
• Proper error chaining (BucketIApi.api_delete_bucket)
• Bucket tests: test_bucket_get_capacity - allow editing values?

src/common/page.rs

• CoerciblePage API needs cleanup and renaming
• Make setting overflow unsafe

src/common/memory.rs

• Use std IsAligned whenever it comes out

To Complete

src/tx.rs

• test_tx_truncate_before_write

src/db.rs

• Rework page size determination functions
• Log IO Errors
• test_db_open_initial_mmap_size
• test_open_recover_free_list
• test_db_concurrent_write_to
• test_db_close_pending_tx_rw
• test_db_close_pending_tx_ro
• test_db_update_panic
• test_db_view_panic
• test_db_batch_panic
• test_db_batch_full
• test_db_batch_time
• test_dbunmap
• benchmark_dbbatch_automatic
• benchmark_dbbatch_single
• benchmark_dbbatch_manual10x100

src/freelist.rs

• Freelist.reload
• freelist_merge_with_exist

src/cursor.rs

• Internal api call for getting the root page id and its page_node
