* A legacy value is a config section with a single-line.
* These values may be read from the BasicConfig interface so
the deprecated Config class does not need to be exposed to
clients.
* Made Config class more testable.
Remove the use of ec_key parameters and return values from ECDSA crypto
prototypes. Don't store key data into an ec_key variable only to fetch
it back into the original type again. Use uint256 and Blob explicitly.
Pass private keys as uint256, and pass public keys as either pointer and
length or Blob in calls to ECDSA{Sign,Verify}() and {en,de}cryptECIES().
Replace GenerateRootDeterministicKey() with separate functions returning
either the public or private key, since no caller needs both at once.
Simplify the use of GenerateDeterministicKey within RippleAddress. Call
a single routine rather than pass the result of one as input to another.
Add openssl unit with RAII classes for bignum, bn_ctx, and ec_point plus
free utility functions.
Rewrite the functions in GenerateDeterministicKey.cpp to use RAII rather
than explicit cleanup code:
* factor out secp256k1_group and secp256k1_order for reuse rather than
computing them each time
* replace getPublicKey() with serialize_ec_point(), which makes, sets,
and destroys an ec_key internally (sparing the caller those details)
and calls i2o_ECPublicKey() directly
* return bignum rather than ec_key from GenerateRootDeterministicKey()
* return ec_point rather than EC_KEY* from GenerateRootPubKey()
Move ECDSA{Private,Public}Key() to a new ECDSAKey unit.
Move ec_key.h into impl/ since it's no longer used outside crypto/.
Remove now-unused member functions from ec_key.
Change tabs to spaces; trim trailing whitespace (including blank lines).
Legacy workarounds for Visual Studio non thread-safe initialization
of function local objects with static storage duration are removed:
* Remove LeakChecked
* Remove StaticObject
* Remove SharedSingleton
This adds codecs for snappy and lz4, and a new nodeobject codec. The
nodeobject codec provides a highly efficient custom compression scheme
for inner nodes, which make up the majority of nodestore databases.
Non inner node objects are compressed using lz4.
The NuDB backend is modified to use the nodeobject codec. This change
is not backward compatible - older NuDB databases cannot be opened or
imported.
This introduces changes in nudb to improve speed, reduce database size,
and enhance correctness. The most significant change is to store hashes
rather than entire keys in the key file. The output of the hash function
is reduced to 48 bits, and stored directly in buckets.
The API is also modified to introduce a Codec parameter allowing for
compression and decompression to be supported in the implementation
itself rather than callers.
THe data file no longer contains a salt, as the salt is applicable
only to the key and log files. This allows a data file to have multiple
key files with different salt values. To distinguish physical files
belonging to the same logical database, a new field UID is introduced.
The UID is a 64-bit random value generated once on creation and stored
in all three files.
Buckets are zero filled to the end of each block, this is a security
measure to prevent unintended contents of memory getting stored to
disk. NuDB offers the varint integer type, this is identical to
the varint described by Google.
* Add varint
* Add Codec template argument
* Add "api" convenience traits
* Store hash in buckets
* istream can throw short read errors
* Support std::uint8_t format in streams
* Make file classes part of the public interface
* Remove buffers pessimization, replace with buffer
* Consolidate creation utility functions to the same header
* Zero fill unused areas of buckets on disk
* More coverage and improvements to the recover test
* Fix file read/write to loop until all bytes processed
* Add verify_fast, faster verify for large databases
The database version number is incremented to 2; older databases can
no longer be opened and should be deleted.
This reverts the change that makes RocksDBQuick the default settings for
node_db "type=rocksdb". The quick settings can be obtained by setting
"type=rocksdbquick".
RocksDBQuick settings are implicated in memory over-utilization problems
seen recently.
This adds support for a cgi /crawl request, issued over HTTPS to the configured
peer protocol port. The response to the request is a JSON object containing
the node public key, type, and IP address of each directly connected neighbor.
The IP address is suppressed unless the neighbor has requested its address
to be revealed by adding "Crawl: public" to its HTTP headers. This field is
currently set by the peer_private option in the rippled.cfg file.
Insert now blocks when the size of the memory pool exceeds a predefined
threshold. This solves the problem where sustained insertions cause the
memory pool to grow without bound.
* Remove unused members
* SerialIter holds only a pointer and offset now
* Use free functions for some Serializer members
* Use SerialIter in some places instead of Serializer
* Run npm/integration tests without launching rippled, using a
running instance of rippled (possibly in a debugger) instead.
* Works for "npm test" and "mocha"
The LevelDB and HyperLevelDB are removed from the backend choices. Neither
were recommended for production environments. As RocksDB is not available
on Windows platforms yet, the recommended backend choice for Windows is NuDB.
Add metrics to record the number of RPC requests received. Record the number of
node store fetches performed per request. Additionally record the byte size of
each request response and measure the response time of each request in
milliseconds.
A new class, ScopedMetrics, uses the Boost Thead Local Storage mechanism to
efficiently record NodeStore metrics within the same thread.
When sql tries to acquire a lock that is already held, it sleeps for some
microseconds using the usleep function and then try to acquire the lock
again. However, if the HAVE_USLEEP macro is not defined then the sleep
function will be used.
This fix will define HAVE_USLEEP even when it is not already defined by
the system. Although some Linux distros may not define HAVE_USLEEP,
all supported versions provide usleep. If the system does not actually
have a usleep function, then the compiler will flag the error.
