This commit introduces no functional changes but cleans up the
code and shrinks the surface area by removing dead and unused
code, leveraging std:: alternatives to hand-rolled code and
improving comments and documentation.
This commit removes obsolete comments, dead or no longer useful
code, and workarounds for several issues that were present in older
compilers that we no longer support.
Specifically:
- It improves the transaction metadata handling class, simplifying
its use and making it less error-prone.
- It reduces the footprint of the Serializer class by consolidating
code and leveraging templates.
- It cleanups the ST* class hierarchy, removing dead code, improving
and consolidating code to reduce complexity and code duplication.
- It shores up the handling of currency codes and the conversation
between 160-bit currency codes and their string representation.
- It migrates beast::secure_erase to the ripple namespace and uses
a call to OpenSSL_cleanse instead of the custom implementation.
* canonicalize_replace_cache
* canonicalize_replace_client
Now it is clear at the call site that if there are
duplicate copies of the data between the cache and
the caller, which copy gets replaced.
Additionally data parameter is now const-correct.
If it is not going to be replaced (canonicalize_replace_cache),
then the shared_ptr to the client data is const.
* Reduce lock scope on all public functions
* Use TaskQueue to process shard finalization in separate thread
* Store shard last ledger hash and other info in backend
* Use temp SQLite DB versus control file when acquiring
* Remove boost serialization from cmake files
* replace boost::beast::detail::iequals with boost::iequals
* replace deprecated `buffers` function with `make_printable`
* replace boost::beast::detail::ascii_tolower with lambda
* add missing includes
For the functions defined in <ctype.h> the C standard requires
that the value of the int argument be in the range of an
unsigned char, or be EOF. Violation of this requirement
results in undefined behavior.
