* filer: give the SQL stores' key-value reads their own connections
A listing holds the connection its rows are on for the whole iteration, and
FilerStoreWrapper calls maybeReadHardLink -> KvGet from inside that iteration,
so a hard-linked entry needs a second connection while the first is still busy.
Out of one bounded pool that is a deadlock: the listings fill the pool and then
wait for a connection none of them will release, and the wrapper's
context.WithoutCancel leaves the waiters without a deadline, so the filer stays
wedged rather than erroring.
The sqlite store shows it at its sharpest -- it allows a single connection, so
one listing over one hard-linked entry never returns. On postgres with
connection_max_open = 50, 60 concurrent listings over hard-linked entries made
no progress at all.
Key-value reads now run on their own pool, carved out of connection_max_open
rather than added to it, so the operator's cap still bounds what the store opens
against the database. An unbounded pool keeps a single pool: nothing can wait
there. sqlite's single connection becomes two, one per pool, and its writes get
a busy timeout so a write that meets the reader waits instead of failing.

* sqlite: keep both pools on one database, whatever the dbFile spells
A dbFile that already carries URI options got a second "?" appended, which the
driver reads as part of the preceding option value, and a bare :memory: is
private to each connection, so the key-value pool would open its own empty
database and every key-value operation would fail on a missing filemeta.

* filer: keep .system internal folder in the default SQL table
Bucket-table SQL stores read the first path segment under /buckets as a
bucket name. The ListBuckets owner index lives at /buckets/.system/..., so
every write there hit isValidBucket(".system") == false and returned
"invalid bucket name .system", flooding the filer log on the postgres/mysql
backends. Route dot-prefixed internal folders to the default table by their
full path, like any other non-bucket entry.
* filer: keep .system internal folder in the default leveldb3 DB
Same guard as the SQL stores: leveldb3 would otherwise open a separate DB
for the .system owner-index folder instead of keeping it in the default DB.
* filer: keep .system internal folder under the default ydb prefix
Skips a DescribeTable round trip per operation on the .system owner-index
path, which never resolves to a real bucket table.
* filer: keep .system internal folder in the default arangodb collection
Avoids creating a stray collection for the .system owner-index folder.
* Fix chown Input/output error on large file sets (Fixes#7911)
Implemented retry logic for MySQL/MariaDB backend to handle transient errors like deadlocks and timeouts.
* Fix syntax error: missing closing brace
* Refactor: Use %w for error wrapping and errors.As for extraction
* Fix: Disable retry logic inside transactions
* refactoring
* add ec shard size
* address comments
* passing task id
There seems to be a disconnect between the pending tasks created in ActiveTopology and the TaskDetectionResult returned by this function. A taskID is generated locally and used to create pending tasks via AddPendingECShardTask, but this taskID is not stored in the TaskDetectionResult or passed along in any way.
This makes it impossible for the worker that eventually executes the task to know which pending task in ActiveTopology it corresponds to. Without the correct taskID, the worker cannot call AssignTask or CompleteTask on the master, breaking the entire task lifecycle and capacity management feature.
A potential solution is to add a TaskID field to TaskDetectionResult and worker_pb.TaskParams, ensuring the ID is propagated from detection to execution.
* 1 source multiple destinations
* task supports multi source and destination
* ec needs to clean up previous shards
* use erasure coding constants
* getPlanningCapacityUnsafe getEffectiveAvailableCapacityUnsafe should return StorageSlotChange for calculation
* use CanAccommodate to calculate
* remove dead code
* address comments
* fix Mutex Copying in Protobuf Structs
* use constants
* fix estimatedSize
The calculation for estimatedSize only considers source.EstimatedSize and dest.StorageChange, but omits dest.EstimatedSize. The TaskDestination struct has an EstimatedSize field, which seems to be ignored here. This could lead to an incorrect estimation of the total size of data involved in tasks on a disk. The loop should probably also include estimatedSize += dest.EstimatedSize.

The exisitng key-value operation for stores using mysql, postgres, and maybe cassandra are already broken.
The kv is used to store hardlink, filer store signature and replication progress.
So users using hardlink and also uses mysql, postgres, or cassandra will have broken hard links.
Users using filer.sync will need to re-sync the files.
