* 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.
* Use localhost cluster for trace_partial_file_suffix_test
This way we get a predictable 127.0.0.1 in the trace file name
* Skip suspend test of pidof is not available
* Avoid writing to closed trace log
calling fdb_network_stop sends a "close" message to the trace thread,
but the network thread might can still be running and sending "flush"
messages to the network thread. This change basically ignores any
flushes that come after a close.
* Ensure unique ports for multi-process tests
1. Introduce processDiskReadSeconds and processDiskWriteSeconds, which stands for disk read/write times `since the last logging`. They can only be obtained on Linux and macOS, and will be 0 on Windows and FreeBSD;
2. Rename `busyTicks` to `IOMilliSecs`;
3. On FreeBSD, the metrics should be collected among all devices.
* Revert "Revert "Refactor: ClusterController driving cluster-recovery state machine""
Major changes includes:
1. Re-revert Sequencer refactor commits listed below (in listed order):
1.a. This reverts commit bb17e194d9.
1.b. This reverts commit d174bb2e06.
1.c. This reverts commit 30b05b469c.
2. Update Status.actor to track ClusterController interface to track
recovery status.
3. Introduce a ServerKnob to define "cluster recovery trace event"
prefix; for now keeping it as "Master", however, it should allow
smooth transition to "Cluster" prefix as it seems more appropriate.
At present, cluster recovery process consists of following steps:
1. ClusterController clusterWatchDatabase actor recruits
master/sequencer process.
2. Sequencer process implements the cluster recovery state machine,
responsible to recruit all other processes as well restore the
cluster state.
Patch proposes a scheme where the cluster recovery state machine
is implemented and driven by the ClusterController process instead
of the Sequencer process.
Advantages of the scheme could be:
1. Simplified design where ClusterController recruits "sequencer"
process like other worker processes compared to current scheme
where "sequencer" process gets special treatment. In newer scheme
sequencer is responsible for maintaining/providing
"committed version" (as expected).
2. ClusterController is responsible for worker processes recruitment,
the sequencer though orchestrating the recovery state machine, it
need to reachout to the ClusterController for recruiting worker
processes etc.
NOTE:
Patch has moved the recovery state machine code from
'sequencer' -> 'cluster-controller' process, however, necessary
updates were done for both functionality as well as performance
improvement reasons.
Next Steps:
Cluster recovery documentation will be updated in near future.
We had been disabling -Wdelete-non-virtual-dtor, because this seems to be done intentionally in the generated code of the actor compiler. I spent some time trying to rewrite it in a way that doesn't literally delete/destroy through a pointer to a base class without a virtual destructor, but I was unable to come up with something that passes correctness. My best guess is that we do this so that we can destroy actor state classes, call callbacks registered on the actor SAV, and then destroy the SAV.
Anyway now we'll detect new usages of deleting through a pointer to a base class without a virtual destructor.
