TokenSign was copying unused Arena held by Standalone instead of refering to it.
An Arena has to be used at least once before it holds a valid, copyable reference.
Otherwise the lifecycle of the copied Arena would be its own and not be shared with the original.
Thus, when the copied arena went out of scope,
the memory supposed to be held by returned Standalone also got released.
Fix: instead of copying, refer to Standalone's arena.
* Add tryResolveHostnames() in connection string.
* Add missing hostname to related interfaces.
* Do not pass RequestStream into *GetReplyFromHostname() functions.
Because we are using new RequestStream for each request anyways. Also, the passed in pointer could be nullptr, which results in seg faults.
* Add dynamic hostname resolve and reconnect intervals.
* Address comments.
Code is still untested at this point, but testing code was written

* Set default for USE_JEMALLOC initially in ConfigureCompiler
Instead of trying to change the value later on. This fixes the valgrind
build, which was previously incorrectly getting jemalloc involved.
* Check aligned_alloc result for null
And OOM if so - don't assert
* Check that we can allocate magazines with no internal fragmentation
We may want to do this so that the jemalloc heap profiler has some
knowledge of FastAlloc
* Populate TestFile field for noSim tests in TestHarness
* Remove handling for nonexistent "ActualRun"
* Add contrib/debug_determinism
Add an instrumentation-based technique for debugging unseen mismatches. Also guard a few existing sources of nondeterminism that don't affect unseen with the DEBUG_DETERMINISM macro.
Also change the simulated run loop to not run as the only task inside the real run loop, since that was a source of nondeterminism.
Also fix nondeterminism from calling timer_int
* Add StorageMetadataType::currentTime
Basically a deterministic-in-simulation version of timer_int that we can
use instead of timer_int for StorageMetadataType::createdTime
* Upgrade AES 128 GCM -> AES 256, StreamCipher code refactor
Major changes proposed are:
1. Refactor StreamCipher code to enable instantiation of
multiple encryption keys. However, code still retains
a globalEncryption key semantics used in Backup file
encryption usecase.
2. Enhance StreamCipher to provide HMAC signature digest
generation. Further, the class implements HMAC encryption
key derivation function.
3. Upgrade StreamCipher to use AES 256 GCM mode from currently
supported AES 128 GCM mode.
Note: The code changes the encryption key size, however, the
feature is NOT currently in use, hence, should be OK.
3. Add EncryptionOps validation and benchmark toml supported
workload, it does the following:
a. Allow user to configure encrypt-decrypt of a fixed size
buffer or variable size buffer [100, 512K]
b. Allow user to configure number of interactions of the runs,
in each iteration: generate random data, derive an encryption
key using HMAC SHA256 method, encrypt data and
then decrypt data. It collects following metrics:
i) time taken to derive encryption key.
ii) time taken to encrypt the buffer.
iii) time taken to decrypt the buffer.
iv) total bytes encrypted and/or decrypted
c. Along with stats it basic basic validations on the encrypted
and decrypted buffer
d. On completion for test, records the above mentioned metrics
in trace files.
Major changes includes:
1. Add a new FDB role responsible- EncyrptKeyProxy. The role is
responsible to expose APIs to fetch encyrption keys interacting
with external Encryption KeyManager interface.
2. The process is a FDB singleton process following similar recruitment
rules as other singleton processes in the system.
3. Code to recruit the worker process; given the encryption keys are
needed during recovery (decode TLog records), for now the process
is co-located in same datacenter as ClusterController.
4. Skeleton process actor code; more functionality will be added in
subsequent PRs.
NOTE: The code is protected under a SERVER_KNOB with the default
value as 'false' for now.
This eliminates many useless warnings when compiling.

* Redwood files now growth in large page chunks controlled by a knob to reduce truncate() calls for expansion. PriorityMultiLock has limit on consecutive same-priority lock release. Increased Redwood max priority level to 3 for more separation at higher BTree levels.
* Simulation fix, don't mark certain IO timeout errors as injected unless the simulated process has been set to have an unreliable disk.
* Pager writes now truncate gradually upward, one chunk at a time, in response to writes, which wait on only the necessary truncate operations. Increased buggified chunk size because truncate can be very slow in simulation.
* In simulation, ioTimeoutError() and ioDegradedOrTimeoutError() will wait until at least the target timeout interval past the point when simulation is sped up.
* PriorityMultiLock::toString() prints more info and is now public.
* Added queued time to PriorityMultiLock.
* Bug fix to handle when speedUpSimulation changes later than the configured time.
* Refactored mutation application in leaf nodes to do fewer comparisons and do in place value updates if the new value is the same size as the old value.
* Renamed updatingInPlace to updatingDeltaTree for clarity. Inlined switchToLinearMerge() since it is only used in one place.
* Updated extendToCover to be more clear by passing in the old extension future as a parameter. Fixed initialization warning.
