* Updated more KV basic tests to run all four device types as part of the test
* Categorized tests as "Smokes" to give good representation of tests that can be used as CI smokes
* Made MemoryLogCompactionTest1 to do four device type tests as need at least one compaction test to test all four device types. Not part of smokes
* Investigated why couple tests failed on LocalMemory device Type and either filed bugs or fixed code. Also, commented out two duplicate tests.
* Removed three duplicate tests ... guessing a merge issue at some point.
* Updated CommitAsyncPrevTask to not use Sleep since there is wait on the current task
* Removed a sleep in ManagedLocalStoreBasicTest as wasn't needed since the commit had true for parametre (wait until commit finishes before moving on)
* Updated WaitForCommitBasicTest to be multi threaded instead of using Sleep().
* Updated TearDown as it was missing the DeleteDirectory() call.
* Various test cleanup
- Centralize "RunAzureTests" checking
- Change GenericLogCompactionTests to illustrate using TestContext.CurrentContext.Test.Arguments
- Resolve bugs
- #142980 - Blob not exist exception in Dispose so use Try \ Catch to make sure tests run without issues
- #143432 - DeltaLogTest on LocalMemory is only returning 50 items when should be returning 200
- #143433 - RecoveryTestFullCheckpoint - LocalMemory only - only reading 1 item when other devices reading all 16384 items
* Throw if incompatible sector sizes when writing files. Add Recovery tests by allocator type, and include failure tests of the sector-size throw
* Clean up AzureStorageDevice to use GetAwaiter().OnComplete instead of unawaited ContinueWith(); fixes the following bugs:
- Completes the fix for #143131 (fht.Log.Scan failing to get proper value on EmulatedAzure only) TestUtils.CreateTestDevice now uses Path.GetFileName(fileName) rather than a constant string
- Fixes#136259 (ReadFlags.SkipReadCache part of ReadAtAddress - SingleReader needs to be fixed to match SingleWriter)

* Brought back TryEnqueue2 and working on timing of CommitFalse
* Simplified CommitFalse - trying figure out why failing on release in CI
* Commented out a few tests that take 10+ minutes to run on release to try to narrow down cause of release running so long
* Removed comments so all tests are running again ...
* Fixed a timing issue where TearDown was delaying a long time under release builds
* Removing EnqueueAndWaitForCommit test and also changing TearDown to see if that helps issue where Release is timing out
* Had a bug in clean up code that caused fails, but looks like timing issue could potentially be fixed
* Added Try \ Catch to clean up code

* Added ReadyToCompletePendingAsyncTest
* Names with Generic were hard to figure out what tests were so changed name to be a bit more descriptiive. Also added a couple tests
* Added EnqueueAndWaitForCommitAsync tests
* Added EnqueueAndWaitForCommitBasicTest where using task.run instead of launching threads. Also combined EnqueueAndWaitForCommitAsyncEntry into one test instead of three separate
* Setting EnqueueAndWaitForCommitBasicTest to run for debug only for now as for some reason when this is run for release it causes tests to bog down where they take minutes instead of a sec or two
* Running EnqueueAndWaitForCommit on Release with reduced test data size to see if that was problem on Release test run
* Set EnqueueAndWaitForCommitBasicTest to only run on Debug builds ... also other checkins for Check point test
* Trying Release run of Enqueue And Wait test. Was a long test name so reduced that. Also, set pipeline timeoutInMinutes: 120
* Shortening test name .. have seen issues with Azure where long names caused weird failures
* Fixed EnqueueWaitCommitBasicTest - wasn't waiting for tasks to finish.
* Cleaned up WaitForCommitBasicTest to use tasks instead of threads.

* Updated testcases to not print anything to stdout, sped up some tests
* Clean up targetframework stuff:
- Change the order in the csproj so netstandard2.1 is first, which appears to be the one that's used by the IDE for #if <TargetFramework> resolution
- Switch to the TargetFramework preprocessor symbols already defined by the build system (we use NETSTANDARD and NETSTANDARD2_1)
- Add Microsoft.Bcl.AsyncInterfaces for pre-netstandard2.1 frameworks, which allows IAsyncEnumerable to work
- Added tests for FasterLogIterator.GetAsyncEnumerable()
- Enable netcore2.2 in FASTER.tests.csproj
* Fix DeviceFasterLogTests hang with IAsyncEnumerator; add tests for FasterLogIterator.GetAsyncEnumerable(MemoryPool<T>)
* Update azure-pipelines.yml
Put UseDotNet@2 task in the right place

* Add VSTest2 pipeline task for Linux
* use DotNetCoreCLI@2 task to run Linux tests
* Specify framework version on C# Linux dotnetcorecli task
* Replace directory separator in tests with front slash (/) for Linux compatibility.

* Add an asynchronous version of recovery to FasterKV, via a `RecoverAsync` API.
* Replace `Thread.Sleep` in the sync Recovery version with `Wait` on a semaphore.
* Add new recovery testcase
* Increase use of `CancellationToken` in FASTER source code
* Misc. bugfixes
* Added NeedCopyUpdate in functions, to avoid allocation if we do not need to CopyUpdate.
* Adding default TryAddFunctions for users to use directly, to perform TryAdd.
* Updated HelloWorld sample to show use of TryAdd session
* Fix async object retrieval when tombstones set on objects
* Improvements to API
* Check specific log checkpoint type during recovery.
* Updated and reorganized samples
* Use 1L << 20 cache lines as hash table size default on all samples and tests (64MB total size)
* Update docs
* Fix directory creation in ManagedLocalStorageDevice
* Fixes issue on Linux devices, where parallel reads on same fine handle are unsupported. We already sequentialize for Writes, this bugfix applies this to Reads as well.
* Renaming IDevice.Close to IDevice.Dispose (#313). This is a breaking change in order to introduce uniformity in the new API. But we have added an extension method for Close with an Obsolete tag for compatibility.
* FasterKV sample using Azure storage device backend. (#314)
* Removed generic new constraint on keys and values in FASTER
* Added default serializer for generic keys and values, based on DataContractSerializer
* Changed serializer ref params to in and out
* Added specialized fast binary serializers for byte[] and string types
* Added testcase for byte arrays
* Fixing intermitted test breaks due to Directory access exception
* Creates three generic pluggable interfaces:
* Naming checkpoints (`ICheckpointNamingScheme`)
* Factory for devices used in checkponts (`INamedDeviceFactory`)
* Pluggable blob management (`IBlobManager`)
* Implements a single general combined log commit & checkpoint manager for any `IDevice` (provided using the factory mentioned above): `DeviceLogCommitCheckpointManager`
* Adds improved `AzureStorageDevice` with user-controlled support for leases via `IBlobManager` interface
* Added checksums for index and log checkpoints (instead of separate `completed.dat` file)
* Implemented iterator for variable length structs.
Current IFasterScanIterator interface is not suited for variable length structs as GetNext would only return a fragment of key/value (up to sizeof(Key)/sizeof(Value)). To solve this issue two new methods were added ref GetKey()/ref GetValue() that return references to actual key/value references in hlog.
There is disconnect in GenericScanIterator as it returns a reference to a copy of key/value and not direct reference to hlog. In case this is needed we could have flag to indicate whether we need to read from frame or hlog directly and store current page/offset.
* Return VariableLengthBlittableScanIterator from VariableLengthBlittableAllocator.Scan
* Added capacity to record when using variable length struct allocator.
Added a check for in-place modifications, allocator can override the method to check for available space, if there is not enough space then a new record will be created.
* Return estimated record size if stored capacity is 0.
* ConcurrentWriter/InPlaceUpdater returns bool to indicate whether it is possible to update record in place.
* Initial implementation of variable length compaction.
* Added Delete to IFasterKV.
* Variable length/blittable iterator - load record info from frame or hlog memory depending on whether the current address is in hlog memory or on disk (loaded to frame).
* Initial commit for rough prototype of single threaded log compaction
* Added two testcases for log compaction over blittable log
* First checkin for native delete support (via tombstones if record cannot be deleted outright from memory).
* Updates
* Fixing corner cases for deletes mixed with RMW and Upsert operations. An Upsert/RMW after a delete will create a new record at the tail. We never unset Tombstone bit - necessary for correctness.
* Further commits and testcases for log compaction
* Added code to correctly handle mutable region during log compaction, using a mix of log scan and lookup via hash table.
* Added testcases for log compaction with generic objects.
* Fixing receiving async callbacks after dispose
* Added long running sample, small fixes, added CurrentAddress to scan API.
* Updates
* Update
* Fixing testcase dir paths
* Initial checkin
* Removed Key* from benchmarks
* Changed callback functions from static to object.
* Removed raw pointers to Value type.
* All user types are now ref-based.
* Generic version of FASTER compiles and works fine for blittable types, for in-memory operations. BasicFASTERTests test cases now pass. There is no performance regression for 50:50 read/upsert YCSB workload. ManagedSample1 is now based on generic FASTER. Support for non-blittable objects has not yet been added. Codegen fails - but can be ignored for now.
* Updates to support generic version
* Updates to refactor allocator
* Testing alt allocator structure
* Fully working generic support, still needs cleanup
* Fixed multi-threading bug with generic allocator.
* Further updates, object recovery not yet passing.
* Fixes to generic object recovery. All tests pass! Cleanup still pending.
* Update samples
* More cleanup and refactoring
* More cleanup and code cutting.
* Heavy simplification of user API and interfaces.
* Removed InitialValueLength from user callback functions
* Updating AddressInfo calculation for AnyCPU 32-bit compat. Other cleanup.
* Cleanup of inlining directives
* Changing key comparer to use a separate IFasterEqualityComparer<T> interface. Now, there are no interface restrictions or requirements on any of the FASTER key/value types.
* Cleanup, simplification, updates. Persistence API cleaned up as well.
* Simplifying Guid determination for persistence callback.
* Fixing test break in AnyCPU-Debug due to different struct layout.
* Fixing the checkpointing directory settings and log creation and initialization code.
