Extend flat_buffer to support unordered_set (de)serialize
Description
Extend flat_buffer to support unordered_set (de)serialize
Testing
Added unit test in flat_buffers.cpp to validate the functionality:
1. Empty unordered_set (de)serialize
1. Non-Empty unordered_set (de)serialize
* Introduce BlobCipher interface and cipher caching interface
diff-3: Update the code to avoid deriving encryption key periodically.
Implement EncyrptBuf interface to limit memcpys.
Improve both unit test and simulation to better code coverage.
diff-2: Add specific error code for OpenSSL AES call failures
diff-1: Update encryption scheme to AES-256-CTR. Minor
updates to Header to capture more information.
Major changes proposed are:
1. Introduce encyrption header format.
2. Introduce a BlobCipher cipher key representation encoding
following information: baseCipher details, derived encryption cipher
details, creationTime and random salt.
3. Introduce interface to support block cipher encrytion and decrytion
operations. Encyrption populates encryption header allowing client to
persist them on-disk, this header is then read allowing decryption
on reads.
4. Introduce interface to allow in-memory caching of cipher keys. The
cache allowing mapping of "encryption domain" -> "base cipher id" ->
"derived cipher keys" (3D hash map). This cache interface will be used
by FDB processes participating in encryption to cache recently used
ciphers (performance optimization).
Testing:
1. Unit test to validate caching interface.
2. Update EncryptionOps simulation test to validate block cipher
operations.
In this patch, for a given test, it is possible to override the knob
values, e.g.
[[test]]
[[test.knobs]]
watch_timeout = 999
will set the client knob WATCH_TIMEOUT to 999 during the test. The
original value will be recovered after the test is over.
* 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"
MacOS warnings are format warnings, e.g., `format specifies type 'long' but the argument has type 'Version' (aka 'long long')`.
Windows warnings are `ACTOR does not contain a wait() statement`.
