* various changes from indexing work (#562) * various changes from indexing work - Add BeginAddress and EndAddress to scan iterators - Allow null deltaFileDevice in HybridLogCheckpointInfo.Recover - Rename FoldOverSnapshot to useFoldOverCheckpoint - Make TakeHybridLogCheckpoint overload call through to overload to avoid duplication - Add default values to new scanDelta and recoverTo arguments - Add missing checkpointManager.OnRecovery call to IntenralRecoverAsync - Fix some comments * Fix shortened name in test to work on Linux * [C#] Record-expiration support in RMW (#545) * Add support for record-expiration management to RMW and I(Advanced)Functions * Update Remote to RMW changes for expiration support * moving remote to IAdvFun * LogDir semantics - minor update Co-authored-by: Badrish Chandramouli <badrishc@microsoft.com> * [C#] Added PostCopyUpdater to IAdvancedFunctions (#561) * Add support for record-expiration management to RMW and I(Advanced)Functions * Update Remote to RMW changes for expiration support * Added PCU * Fixing testcase so that RMW does not expect old address. * Fix PCU bugs * Extend PostCopyUpdate to IFunctions; fix a few comments in remote Co-authored-by: TedHartMS <15467143+TedHartMS@users.noreply.github.com> * [C#] Merge IAdvancedFunctions into IFunctions (#565) * Merge IAdvancedFunctions into IFunctions * Add SupportsPostOperations and Post(IU|CU|SD); expand "ref RecordInfo recordInfo, long address" on Functions * Add RecordMetadata to RMWCompletionCallback params; improve ReadAddressTests * Add tests of Upsert with Input * [C#] RecordInfo v2 (#577) * RecordInfo v2 * fix version jump in CPR. * Updated misc stuff * misc updates to SpanByte * Remove IntExclLocker * Add Try APIs to record locking * Remove FASTERLegacy (#581) * Add Output parameter to Upsert (#574) * Add overloads of Upsert that take "ref Output" and one that takes "out RecordMetadata"; Fix RMW setting pendingContext.RecordInfo/LA; add locking of PostCopyUpdater, PostInitalUpdater, PostSingleWriter; * Reorganize ClientSession IntenralFasterSession to group functions for a given area (Read, Upsert, RMW, etc.) together * Fix locking on Post* calls * Fixes for Post* locking * remove net461 and netcoreapp2.1; add net6.0 in <Choose> to work on later in VS2022 * Update to new RecordInfo locking calls * Update to new IFunctions Locking signatures and RecordInfo implementation * Add post operations to Faster.benchmark * [C#] Checkpoint, Recovery, RecordInfo updates (#588) * Removed WAIT_PENDING * * Use only 1 bit for newVersion in RecordInfo, for CPR. Semantics are that sessions in v+1 will create records in fuzzy region with this bit set. Recovery only scans fuzzy region to elide such records. * Add 1 Filler bit for future use with fillers in records * Increase read lock bits to 6 (64 parallel readers) * Use dirty bit for incremental checkpoints * fix ycsb to not delete data file if we are using --recover * Fix epoch re-entry violation * Move to long versions, for KV checkpoints. * Shuffle around stuff for better cache alignment in benchmark. * Updates based on review * [C#] FasterLog Commit Optimization (v2) (#587) * Checkpoint work * Add notion of manual commit * Recovery of commit cookie * alternative design of log-cookie * Implementation improvement * code review comments * Cleanup + testing * Add management utility for LogCommitManager * Handle race on manual commit code path where not the latest tail is written out * Add condition to only scan log in fastCommitMode * Rough draft to allow for 1. elided commit record when fastCommit turned off and 2.

Co-authored-by: Badrish Chandramouli <badrishc@microsoft.com> * Remove legacy local log commit manager * [C#] FasterLog v2 - misc changes, removed OverWrite commits (#593) * Checkin misc changes, removed overWrite commits * simplify OnRecovery logic * Fix build after merge * fix alignment of device commit manager * [C#] v2 pending flush list (#596) * Make PendingFlushList never error out in stressful situations. Current implementation uses lock for ~5-10% perf degradation over prior structure. * [C#] FasterLog v2: Fix FasterLog missed final commit (#597) * Fix FasterLog missed final commit. * [C#] Log compaction v2 (#598) * initial checkin * New ShiftBeginAddress behavior -- only shifts BeginAddress variable and does not truncate physical log unless option is specified. Also added Log.Truncate API for physical log truncation. Truncate log until persisted BeginAddress after taking a checkpoint. * Fix epoch protection orderings. * minor improvement to TestUtils to avoid race exception. * update Program.cs * updates from master. * [C#] V2 Custom Commit Strategy (#599) * Add FasterLogCommitStrategy * Use Bakery algorithm for latch * Documentation + tests + improved threading performance * Fix initialization error * Revert to v2 synchronization scheme * Optimization around commit strategies * Refactor CommitPolicy only for normal commits * fix missing spin wait * [C#] Fix v2 CommitPolicy Warnings (#607) * fix warnings * fix broken test * update for code consistency * Merged PR 59053: Network Stack Refactoring into FASTER This pull request contains the necessary changes for the updated network stack interface used by FASTER. It adds INetworkSender.cs and NetworkSenderBase.cs that can be used to implement custom communication protocols. Currently only TcpNetworkSender is supported. * Create .dockerignore * Added TentativeHeadAddress - we first shift this, and when all threads agree, we can do some pre-closing work such as eviction. Then we can shift the actual HeadAddress, closing pages when all threads agree on this. (#608) * Cleanup and remove dead code + reuse base provider. * Code cleanup * [C#] minor cleanup of fasterlog v2 (#611) * minor cleanup of fasterlog * [C#] Remove CheckpointType from CheckpointSettings (v2) (#614) * Remove CheckpointType from CheckpointSettings. Users have to specify checkpoint type on a per checkpoint basis. * fix build break * Fix CTT to call PostSingleWriter. * Avoid double init of FasterLog * [C#] Fixing warnings (#615) * Fixing CI warnings * [C#] Updating dependent package versions in v2 (#616) * Updating dependent package versions * nit * [C#] Improved FasterKV and FasterLog settings API for v2 (#618) * Simpler config API for v2. Move FasterLog to its own folder. * Remove purgeEarlierCommits from reader. Instead: 1. writer retries file deletes (in device commit manager) if access denied, in a loop, until timeout 2. reader (user code) retries recover async if it fails due to file deleted, until timeout * [C#] FasterLog V2 Device error handling (#612) * prototype device * prototype failure handling * Add proposed error handling code * Basic error handling tasks * Fault tolerant devices * Change to failure handler based approach instead of just throwing an exception * Remove brittle error handling code * make sure to read pages from flaky device on recovery in test * fix warnings * code review comments * See if we can enforce clean shutdown * Add extensions to enqueue SpanByte to FasterLog, and unsafely iterate without memory copy.
