* db: migrate from lmdb-zero to heed * fix: check resizing operation and wait to avoid crash with multiple batches, fix exists check at batch * build: fix missing deps at Cargo.lock * lmdb: single environment, migrate existing databases with provided non-default environment name * fix: revert chunk size to 128mb * lmdb: ability to use multiple shared environments * build: remove unused dependency * fix: resize to have correct multiplier of the system page size * lmdb: speed up prefix iter by storing keys * lmdb: default env name * lmdb: wait db resize before read, reduce timeout before resizing * lmdb: use static reader for iterator, count existing batches for stable resize * fix: check batches count on resize waiting * lmdb: use separate databases instead of prefixes, use default db for values without prefixes, migrate old environment * fix: pop pos key * lmdb: count all open transactions to finish before resizing * lmdb: immediate resize if there are no open transactions * lmdb: remove env state when there are no more stores * lmdb: use atomic for resize and resize checking flags * lmdb: sleep 10ms when waiting all opened txs to be closed * lmdb: use atomic open txs and stores count * lmdb: use index to detect separator, ignore unknown db key to not have a panic * lmdb: store max 10k keys in the iterator * lmdb: check iter result on getting total * lmdb: handle errors at iterator * lmdb: handle an error when db with provided key not found * lmdb: fix iterate over 10k keys * lmdb: document migration resize safety * lmdb: fix iter test * lmdb: clear new db after unsuccessful migration, handle read error on migration to interrupt process * store: bring back old key methods to reproduce data migration * lmdb: return an error on unsuccessful migration * lmdb: migration test, clean data after allocate test * lmdb: info migration log * fix: move iterator before handling an error to allow skip bad value * lmdb: return an error if removal of old DB file failed after migration * lmdb: lifetime for iterator, use write transaction at batch iterator * lmdb: migration progress * fix: tests * lmdb: immediately set resizing flag, ignore resizing flag while there are more than 0 opened txs to avoid stuck, optimize tx counter for some operations * lmdb: key for successful migration * lmdb: fix put database creation at separate block to avoid lifetime issues when returning an error on migration
