Calculate the number of file descriptors that are needed during
execution based on the configuration file, with a hard floor
of 1024, adjusting the limit if possible. Refuse to run if enough
fds are not available.
Additionally, allow administrators to limit the number of incoming
connections a configured port will accept. By default no limit is
imposed.
Replace Journal public data members with member function accessors
in order to make Journal lighter weight. The change makes a
Journal cheaper to pass by value.
Also add missing stream checks (e.g., calls to JLOG) to avoid
text processing that ultimately will not be stored in the log.
The IP address used to perform pathfinding operations is now charged an
additional resource increment for each source currency in the path set.
* NOTE: This charge is a local resource charge, not a transaction fee
charge.
The Journal API is affected. There are two uses for the
Journal::Severity enum:
o It is used to declare a threshold which log messages must meet
in order to be logged.
o It declares the current logging level which will be compared
to the threshold.
Those uses that affect the threshold are now named threshold()
rather than severity() to make the uses easier to distinguish.
Additionally, Journal no longer carries a Severity variable.
All handling of the threshold() is now delegated to the
Journal::Sink.
Sinks are no longer constructed with a default threshold of
kWarning; their threshold must be passed in on construction.
These changes ensure the caller can block until the
Application object can be fully prepared (especially
listening sockets). Solves the problem where tests
can attempt connections before the server sockets are
ready.
* WebSocket blocks until listening
* Application setup blocks until prepared and started
* A new, unified interface for generating random numbers and
filling buffers supporting any engine that fits the
UniformRandomNumberGenerator concept;
* Automatically seeded replacement for rand using the fast
xorshift+ PRNG engine;
* A CSPRNG engine that can be used with the new framework
when needing to to generate cryptographically secure
randomness.
* Unit test cleanups to work with new engine.
These changes eliminate the Env's OpenLedger member and make
transactions go through the Application associated with each
instance of the Env, making the unit tests follow a code path
closer to the production code path.
* Add Env::open() for open ledger
* Add Env::now()
* Rename to Env::current()
* Inject ManualTimeKeeper in Env Application
* Make Config mutable
* Move setupConfigForUnitTests
* Launch Env Application thread
* Use Application ledgers in Env
* Adjust Application clock on ledger close
* Adjust close time for close resolution
* Scrub obsolete clock types
* Enable features via Env ctor
* Make Env::master Account object global
* Cache SSL context (performance)
* Cache master wallet keys in Ledger ctor (performance)
* SConstruct will set ABI based on ubuntu flavor
* Script to bring in packages for various ubuntu flavors
* Script to bring in packages for various fedora 22
* Remove unneeded environment variable from travis
* Script to build boost with correct API flags
* `--static` flag to control static linking
o The sign_for RPC command automatically fills in an empty
"SigningPubKey" field if the field is missing.
o The sign_for command returns the Signers list inside the
tx_json. This re-establishes symmetry with the
submit_multisigned command. It also means the returned
tx_blob might be useful, since it contains the multisignature.
o The sign_for command also now allows the inclusion of a Signers
array field in the input tx_json. If a Signers array is present,
the new signature is incorporated into the passed array. This
supports a model where multisignatures are accumulated serially.
o Syntax hints are improved.
o Remove warning written to log by sign_for command.
o The sign_for RPC command previously only worked in the
"json sign_for" form. The command now works as a straight
"sign_for". The "offline" parameter also works.
o Don't autofill Fee or Paths when signing offline.
This change causes each instance of Env to construct its own
isolated Application object for testing. Also included is
part of a framework to create multiple Application objects
in the same unit test and connect them together.
Eventually multisign will need to be enabled onto the network, at
which point compiling it in or out will no longer be an option.
In preparation, the compile guards are removed and multisign is
being enabled with a Feature.
You can locally enable a Feature using your config file. To
enable multisign with your config file add a section like this:
[features]
MultiSign
The exact spelling and capitalization of both "features" and
"MultiSign" is important. If you don't get those right multisign
will not be enabled.
There is a minor issue. The "sign_for" and "submit_multisigned"
RPC commands are only enabled if multisign is enabled. However
those commands are still shown in the help message even if
multisign is disabled. This is because the code that produces
the help message doesn't read the config file (where the Features
are kept). This problem will become irrelevant once multisign is
enabled onto the network.
These routines replace existing code to compute SHA512-Half hashes.
The new code accumulates serialized data into a hashing context
instead of allocating a buffer, for improved performance.
This commit provides support for 2-level multi-signing of
transactions. The ability is usually compiled out, since other
aspects of multi-signing are not yet complete.
Here are the missing parts:
o Full support for Tickets in transactions.
o Variable fees based on the number of signers,
o Multiple SignerLists with access control flags on accounts,
o Enable / disable operations based on access control flags,
o Enable / disable all of multi-signing based on an amendment,
o Integration tests, and
o Documentation.
Add support for the SignerListSet transaction as a step toward
multi-sign support.
As part of the SignerListSet implementation, add InnerObjectFormat
templates (similar to TxFormats and LedgerFormats) and enforce them
in STObject, STArray, and STParsedJSON.
* Remove the deprecated wallet_accounts command.
* Remove dead code for generator maps.
* Remove the help for the obsolete wallet_add and wallet_claim commands
(which have already been removed).
* Brings the soci subtree into rippled.
* Validator, peerfinder, and SHAMapStore use new soci backend.
* Optional postgresql backend for soci (if POSTGRESQL_ROOT env var is set).
* When starting up, we no longer rely just on the standard
system RNG to generate entropy: we attempt to squeeze some
from the execution state, and to recover any entropy that
we had previously stored.
* When shutting down, if sufficient entropy has been accumulated
attempt to store it for future use.
