* Tally and duration counters for Job Queue tasks and RPC calls
optionally rendered by server_info and server_state, and
optionally printed to a distinct log file.
- Tally each Job Queue task as it is queued, starts, and
finishes running. Track total duration queued and running.
- Tally each RPC call as it starts and either finishes
successfully or throws an exception. Track total running
duration for each.
* Track currently executing Job Queue tasks and RPC methods
along with durations.
* Json-formatted performance log file written by a dedicated
thread, for above-described data.
* New optional parameter, "counters", for server_info and
server_state. If set, render Job Queue and RPC call counters
as well as currently executing tasks.
* New configuration section, "[perf]", to optionally control
performance logging to a file.
* Support optional sub-second periods when rendering human-readable
time points.
* The compiler can provide many non-explicit constructors for
aggregate types. This is sometimes desired, but it can
happen accidentally, resulting in run-time errors.
* This commit assures that no types are aggregates unless existing
code is using aggregate initialization.
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.
Per issue #2354, when the log level of a server was configured at
"trace", sensitive keying meterial generated by the `wallet_propose`
command could be written to the server's log file, if one was
configured.
This commit improves the log scrubbing code to account for the
sensitive information generated by a `wallet_propose`.
** Important security consideration **
We still caution everyone *against* executing this command on a
server that they do not control: a malicious server operator could
intercept the generated keypair, or operate a modified server that
returns keypairs that are not securely generated.
* If any of the destructor, copy assignment or copy constructor
are user-declared, both copy members should be user-declared,
otherwise the compiler-generation of them is deprecated.
- Separate `Scheduler` from `BasicNetwork`.
- Add an event/collector framework for monitoring invariants and calculating statistics.
- Allow distinct network and trust connections between Peers.
- Add a simple routing strategy to support broadcasting arbitrary messages.
- Add a common directed graph (`Digraph`) class for representing network and trust topologies.
- Add a `PeerGroup` class for simpler specification of the trust and network topologies.
- Add a `LedgerOracle` class to ensure distinct ledger histories and simplify branch checking.
- Add a `Submitter` to send transactions in at fixed or random intervals to fixed or random peers.

All uses of beast::Thread were previously removed from the code
base, so beast::Thread is removed. One piece of beast::Thread
needed to be preserved: the ability to set the current thread's
name. So there's now a beast::CurrentThreadName that allows the
current thread's name to be set and returned.
Thread naming is also cleaned up a bit. ThreadName.h and .cpp
are removed since beast::CurrentThreadName does a better job.
ThreadEntry is also removed, but its terminateHandler() is
preserved in TerminateHandler.cpp. The revised terminateHandler()
uses beast::CurrentThreadName to recover the name of the running
thread.
Finally, the NO_LOG_UNHANDLED_EXCEPTIONS #define is removed since
it was discovered that the MacOS debugger preserves the stack
of the original throw even if the terminateHandler() rethrows.
Avoid custom overflow code; simply use 128-bit math to
maintain precision and return a saturated 64-bit value
as the final result.
Disallow use of negative values in the `fee_mult_max`
and `fee_div_max` fields. This change could potentially
cause submissions with negative values that would have
previously succeeded to now fail.
The default SSL cipher list introduced with 0.50.0 in
commit 2c87739 was overly restrictive and resulted in
clients unable to negotiate SSL connections.
Adjust the default cipher to the more sensible:
HIGH:MEDIUM:!aNULL:!MD5:!DSS:!3DES:!RC4:!EXPORT
Correct a bug that would not allow an SSL handshake
to properly complete if the port was configured using
the `wss` keyword.
The existing configuration includes 512 and 1024 bit DH
parameters and supports ciphers such as RC4 and 3DES and
hash algorithms like SHA-1 which are no longer considered
secure.
Going forward, use only 2048-bit DH parameters and define
a new default set of modern ciphers to use:
HIGH:!aNULL:!MD5:!DSS:!SHA1:!3DES:!RC4:!EXPORT:!DSS
Additionally, allow administrators who wish to have different
settings to configure custom global and per-port ciphers suites
in the configuration file using the `ssl_ciphers` directive.
Replace the sparsely used strCopy function with Slice. Change some of
the SHAMap interface to use Slice instead of Blob, which should
eliminate a copy.
Log thread name and exception type on unhandled exceptions and use a
terminate handler to get a stack trace that includes the function that
thows the exception.
Previously, writes using debugLog() tagged every entry with
"TRC:". Now users of debugLog() must specify the severity
level they want their information logged at.
* Updates many (but probably not all) locations that access base_uint
private storage.
* More calls to access base_uint through members.
* Use an iterator to write Serializer collections.
