The original intent was that RPC error codes were not stable.
But those codes were made available through the API, so some
users came to depend on the code values. This change adapts
to the current state of affairs.
Manifests which are revoked can include ephemeral keys although doing
so does not make sense: a revoked manifest isn't used for signing and
so don't need to define an ephemeral key.
A running instance of the server tracks the number of protocol messages
and the number of bytes it sends and receives.
This commit makes the counters more granular, allowing server operators
to better track and understand bandwidth usage.
* Add construction and assignment from a generic
contiguous container. Both compile-time and run time
safety checks are made to ensure the safety of this
conversion.
* Remove base_uint::copyFrom. The generic copy assignment
operator now does this functionality with enhanced
safety and better syntax.
* Remove construction from and dedendence on Blob.
The generic constructor and assignment now handle this
functionality.
* Fix client code to adhere to this new API.
* Removed the use of fromVoid in PeerImp.cpp as it was
an inappropriate use of this dangerous API. The
generic container constructors do it with enhanced
safety and better syntax.
* Rename data member pn to data_ and make it private.
* Remove constraint from hash_append
* Remove array_type alias
This PR addresses a problem where the server could hang indefinitely
on shutdown. The cause of the problem is the SNTPClock class was not
binding the socket to an endpoint on initialization. This can create
an error sent to the read handler. Unfortunately, the handler ignores
the error, reads again and enters into a loop preventing the
io_service from ever completing.
- Use `std::lock` when grabbing multiple mutexes to ensure consistent
locking order and avoid deadlocks.
- Reduce the scope of the master mutex lock by relesing it prior to
calling setHeartbeatTimer
A tiny input amount to a payment step can cause this step to output zero. For
example, if a previous steps outputs a dust amount of 10^-80, and this step is a
IOU -> XRP offer, the offer may output zero drops. In this case, call the strand
dry. Before this patch, an error would be logged, the strand would be called
dry; in debug mode an assert triggered.
Note, this patch is not transaction breaking, as the caller did not user the ter
code. The caller only checked for success or failuer.
This patch addresses github issue issue reported here:
https://github.com/ripple/rippled/issues/2929
This patch removes calls to several deprecated asio functions.
* `io_service::post` becomes `post` (free function)
* `io_service::work` becomes `executor_work_guard`
* `io_service::wrap` becomes `bind_executor`
* `get_io_context` becomes `get_executor` or `get_executor().context()`
This patch was tested with boost 1.69 and 1.70. The functions
`ripple::get_lowest_layer` and `beast::create_waitable_timer` are required to
handle a breaking difference between these versions. When rippled no longer
needs to support pre 1.70 boost versions, both of these functions may be
removed, and the waitable timer injections may also be removed.
The new parse logic is more strict but handles more cases. If an exception
is thrown, just bail.
* Allow parsing unenclosed IPv6 addresses without port
* Improve string construction
* Reduce nesting levels of code
The XRP Ledger allows an account to authorize a secondary key pair,
called a regular key pair, to sign future transactions, while keeping
the master key pair offline.
The regular key pair can be changed as often as desired, without
requiring other changes on the account.
If merged, this commit corrects a minor technical flaw which would
allow an account holder to specify the master key as the account's
new regular key.
The change is controlled by the `fixMasterKeyAsRegularKey` amendment
which, if enabled, will:
1. Prevent specifying an account's master key as the account's
regular key.
2. Prevent the "Disable Master Key" flag from incorrectly affecting
regular keys.
Before this patch, jtx allowed non-invocable functions to be passed to
operator(). However, these arguments are ignored. This caused erronious code
code such as:
```
env (offer (account_to_test, BTC (250), XRP (1000)),
offers (account_to_test, 1));
```
While it looks like the number of offers are checked, they are not. The `offers`
funclet is never run. While we could modify jtx to make the above code correct,
a cleaner solution is to run post conditions in a `require` statement after a
transasction runs.
At this point all of the jss::* names are defined in the same
file. That file has been named JsonFields.h. That file name
has little to do with either JsonStaticStrings (which is what
jss is short for) or with jss. The file is renamed to jss.h
so the file name better reflects what the file contains.
All includes of that file are fixed. A few include order
issues are tidied up along the way.
Formerly an SOTemplate was default constructed and its elements
added using push_back(). This left open the possibility of a
malformed SOTemplate if adding one of the elements caused a throw.
With this commit the SOTemplate requires an initializer_list of
its elements at construction. Elements may not be added after
construction. With this approach either the SOTemplate is fully
constructed with all of its elements or the constructor throws,
which prevents an invalid SOTemplate from even existing.
This change requires all SOTemplate construction to be adjusted
at the call site. Those changes are also in this commit.
The SOE_Flags enum is also renamed to SOEStyle, which harmonizes
the name with other uses in the code base. SOEStyle elements
are renamed (slightly) to have an "soe" prefix rather than "SOE_".
This heads toward reserving identifiers with all upper case for
macros. The new style also aligns with other prominent enums in
the code base like the collection of TER identifiers.
SOElement is adjusted so it can be stored directly in an STL
container, rather than requiring storage in a unique_ptr.
Correspondingly, unique_ptr usage is removed from both
SOTemplate and KnownFormats.
The new 'Domain' field allows validator operators to associate a domain
name with their manifest in a transparent and independently verifiable
fashion.
It is important to point out that while this system can cryptographically
prove that a particular validator claims to be associated with a domain
it does *NOT* prove that the validator is, actually, associated with that
domain.
Domain owners will have to cryptographically attest to operating particular
validators that claim to be associated with that domain. One option for
doing so would be by making available a file over HTTPS under the domain
being claimed, which is verified separately (e.g. by ensuring that the
certificate used to serve the file matches the domain being claimed) and
which contains the long-term master public keys of validator(s) associated
with that domain.
Credit for an early prototype of this idea goes to GitHub user @cryptobrad
who introduced a PR that would allow a validator list publisher to attest
that a particular validator was associated with a domain. The idea may be
worth revisiting as a way of verifying the domain name claimed by the
validator's operator.
Resource limits were not properly applied to connections with
known IP addresses but no corresponding users.
Add unit tests for unlimited vs. limited ports.
An audit showed that a number of the RPC error codes in
ErrorCodes.h are no longer used in the code base. The unused
codes were removed from the file along with their support code
in ErrorCodes.cpp.
The ledger already declared a transaction that is both single-
and multi-signing malformed. This just adds some checking in
the signing RPC commands (like submit and sign_for) which allows
that sort of error to be identified a bit closer to the user.
In the process of adding this code a bug was found in the
RPCCall unit test. That bug is fixed as well.
