Changes:
1. Change `isEncryptionOpSupported` to not check against `clientDBInfo.isEncryptionEnabled`, but instead against ENABLE_ENCRYPTION server knob. The problem with clientDBInfo is before its being broadcast to the workers, its content is uninitialized, during which some data (e.g. item 2) is not getting encrypted when they should.
2. Fix CommitProxy not encrypting metadata mutations which are recovered from txnStateStore
3. Fix KeyValueStoreMemory (thus TxnStateStore) partial transaction coming from recovery is not encrypted
4. new CODE_PROBE for the above fixes
5. Logging changes
* proof of concept
* use code-probe instead of test
* code probe working on gcc
* code probe implemented
* renamed TestProbe to CodeProbe
* fixed refactoring typo
* support filtered output
* print probes at end of simulation
* fix missed probes print
* fix deduplication
* Fix refactoring issues
* revert bad refactor
* make sure file paths are relative
* fix more wrong refactor changes
The erased bytes from recent state transactions was accidently set to 0 and
cause anyPopped to be always false. Thus, when totalStateBytes will never
decrease and can cause high latency between "Resolver.resolveBatch.Before" and
"Resolver.resolveBatch.AfterQueueSizeCheck", in hundreds of milliseconds. This
will cause high server side commit latency.
Adding encryption support for TxnStateStore. It is done by supporting encryption. for KeyValueStoreMemory. The encryption is currently done on operation level when the operations are being write to the underlying log file. See inline comment for the encrypted data format.
This PR depends on #7252. It is part of the effort to support TLog encryption #6942.
This is needed to make sure all Resolvers process all metadata mutations.
For commit proxy, we add all read/write conflict ranges for metadata mutations
to all resolvers.
We also send lock_aware flag for each transaction to resolvers.
Need to be careful what values applyMetadataMutation needs.
Need to call txnStateStore->enableSnapshot() after receiving the broadcast to
allow semiCommit to happen.
