* Ownership of buffer memory in StatsDCollector is passed to the
boost::asio callback function. Before this, the memory may have been
freed before async_send was finished with the memory.
pool_thresh is prevented from going to zero. This solves a problem when
using callgrind where the CPU is monopolized, causing operations that
should complete quickly to take days.
* Performance motivated.
* Several of these called size() which is O(N) in gcc-4.8.
* Remove container copy from LedgerConsensusImp::playbackProposals().
* Addresses RIPD-284.
* Deprecate rpc_admin_allow section from configuration file
* New port-specific setting 'admin':
* Comma-separated list of IP addresses that are allowed administrative
privileges (subject to username & password authentication if configured)
* 127.0.0.1 is no longer a default admin IP.
* 0.0.0.0 may be specified to indicate "any IP" but cannot be combined
with other IP addresses.
The buffers_type::iterator could hold a pointer to a buffers_type that
was destroyed. This changes buffers_type::iterator to point to the
original streambuf instead, which always outlives the iterator.
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 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.
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.
