- Add support for all transaction types and ledger object types to gRPC
implementation of tx and account_tx.
- Create common handlers for tx and account_tx.
- Remove mutex and abort() from gRPC server. JobQueue is stopped before
gRPC server, with all coroutines executed to completion, so no need for
synchronization.
* When an unknown amendment reaches majority, log an error-level
message, and return a `warnings` array on all successful
admin-level RPC calls to `server_info` and `server_state` with
a message describing the problem, and the expected deadline.
* In addition to the `amendment_blocked` flag returned by
`server_info` and `server_state`, return a warning with a more
verbose description when the server is amendment blocked.
* Check on every flag ledger to see if the amendment(s) lose majority.
Logs again if they don't, resumes normal operations if they did.
The intention is to give operators earlier warning that their
instances are in danger of being amendment blocked, which will
hopefully motivate them to update ahead of time.
Remove the implicit conversion from int64 to XRPAmount. The motivation for this
was noticing that many calls to `to_string` with an integer parameter type were
calling the wrong `to_string` function. Since the calls were not prefixed with
`std::`, and there is no ADL to call `std::to_string`, this was converting the
int to an `XRPAmount` and calling `to_string(XRPAmount)`.
Since `to_string(XRPAmount)` did the same thing as `to_string(int)` this error
went undetected.
* The `tx` command now supports min_ledger and max_ledger fields.
* If the requested transaction isn't found and these fields are
provided, the error response indicates whether or not every
ledger in the the provided range was searched.
This fixes#2924
Collecting the returned and expected values in sets only works if there are no
duplicates. The implementation is changed to use sorted vectors to fix this case.
The XRP Ledger utilizes an account model. Unlike systems based on a UTXO
model, XRP Ledger accounts are first-class objects. This design choice
allows the XRP Ledger to offer rich functionality, including the ability
to own objects (offers, escrows, checks, signer lists) as well as other
advanced features, such as key rotation and configurable multi-signing
without needing to change a destination address.
The trade-off is that accounts must be stored on ledger. The XRP Ledger
applies reserve requirements, in XRP, to protect the shared global ledger
from growing excessively large as the result of spam or malicious usage.
Prior to this commit, accounts had been permanent objects; once created,
they could never be deleted.
This commit introduces a new amendment "DeletableAccounts" which, if
enabled, will allow account objects to be deleted by executing the new
"AccountDelete" transaction. Any funds remaining in the account will
be transferred to an account specified in the deletion transaction.
The amendment changes the mechanics of account creation; previously
a new account would have an initial sequence number of 1. Accounts
created after the amendment will have an initial sequence number that
is equal to the ledger in which the account was created.
Accounts can only be deleted if they are not associated with any
obligations (like RippleStates, Escrows, or PayChannels) and if the
current ledger sequence number exceeds the account's sequence number
by at least 256 so that, if recreated, the account can be protected
from transaction replay.
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.
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.
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.
When Ed25519 support was added to ripple-lib, a way to specify
whether a seed should be used to derive a "classic" secp256k1
keypair or a "new" Ed25519 keypair was needed, and the
requirements were that:
1. previously seeds would, correctly, generate a secp256k1
keypair.
2. users would not have to know about whether the seed was
used to generate a secp256k1 or an Ed25519 keypair.
To address these requirements, the decision was made to encode
the type of key within the seed and a custom encoding was
designed.
The encoding uses a token type of 1 and prefixes the actual
seed with a 2 byte header, selected to ensure that all such
keypairs will, when encoded, begin with the string "sEd".
This custom encoding is non-standard and was not previously
documented; as a result, it is not widely supported and other
sofware may treat such keys as invalid. This can make it
difficult for users that have stored such a seed to use
wallets or other tooling that is not based on ripple-lib.
This commit adds support to rippled for automatically
detecting and properly handling such seeds.
The 'validation_seed' RPC command was used to change the validation
key used by a validator at runtime.
Its implementation was commented out with commit fa796a2eb5
which has been included in the codebase since the 0.30.0 release
and there are no plans to reintroduce the functionality at this
point.
Validator operators should migrate to using validator manifests
instead.
This fixes#2748.
The FeeEscalation amendment has been enabled on the XRP Ledger network
since May 19, 2016. The transaction which activated this amendment is:
5B1F1E8E791A9C243DD728680F108FEF1F28F21BA3B202B8F66E7833CA71D3C3.
This change removes all conditional code based around the FeeEscalation
amendment, but leaves the amendment definition itself since removing the
definition would cause nodes to think an unknown amendment was activate
causing them to become amendment blocked.
The commit also removes the redundant precomputed hashes from the
supportedAmendments vector.
A validator that was configured to use a published validator list could
exhibit aberrent behavior if that validator list expired.
This commit introduces additional logic that makes validators operating
with an expired validator list bow out of the consensus process instead
of continuing to publish validations. Normal operation will resume once
a non-expired validator list becomes available.
This commit also enhances status reporting when using the `server_info`
and `validators` commands. Before, only the expiration time of the list
would be returned; now, its current status is also reported in a format
that is clearer.
Problem:
- There are several specific overloads with some custom code that can be
easily replaced using Boost.Hex.
Solution:
- Introduce `strHex(itr, itr)` to return a string given a begin and end
iterator.
- Remove `strHex(itr, size)` in favor of the `strHex(T)` where T is
something that has a `begin()` member function. This allows us to
remove the strHex overloads for `std::string`, Blob, and Slice.
* When increasing the expected ledger size, add on an extra 20%.
* When decreasing the expected ledger size, take the minimum of the
validated ledger size or the old expected size, and subract another 50%.
* Update fee escalation documentation.
* Refactor the FeeMetrics object to use values from Setup
As described in #2314, when an offer executed with `Fill or Kill`
semantics, the server would return `tesSUCCESS` even if the order
couldn't be filled and was aborted. This would require additional
processing of metadata by users to determine the effects of the
transaction.
This commit introduces the `fix1578` amendment which, if enabled,
will cause the server to return the new `tecKILLED` error code
instead of `tesSUCCESS` for `Fill or Kill` orders that could not
be filled.
Additionally, the `fix1578` amendment will prevent the setting of
the `No Ripple` flag on trust lines with negative balance; trying
to set the flag on such a trust line will fail with the new error
code `tecNEGATIVE_BALANCE`.
In order to facilitate transaction signing, `rippled` offers the `sign` and
`sign_for` and `submit` commands, which, given a seed, can be used to sign or
sign-and-submit transactions. These commands are accessible from the command
line, as well as over the WebSocket and RPC interfaces that `rippled` can be
configured to provide.
These commands, unfortunately, have significant security implications:
1. They require divulging an account's seed (commonly known as a "secret
key") to the server.
2. When executing these commands against remote servers, the seeds can be
transported over clear-text links.
3. When executing these commands over the command line, the account
seed may be visible using common tools that show running processes
and may potentially be inadvertently stored by system monitoring
tools or facilities designed to maintain a history of previously
typed commands.
While this commit cannot prevent users from issuing these commands to a
server, whether locally or remotely, it restricts the `sign` and `sign_for`
commands, as well as the `submit` command when used to sign-and-submit,
so that they require administrative privileges on the server.
Server operators that want to allow unrestricted signing can do so by
adding the following stanza to their configuration file:
[signing_support]
true
Ripple discourages server operators from doing so and advises against using
these commands, which will be removed in a future release. If you rely on
these commands for signing, please migrate to a standalone signing solution
as soon as possible. One option is to use `ripple-lib`; documentation is
available at https://developers.ripple.com/rippleapi-reference.html#sign.
If the commands are administratively enabled, the server includes a warning
on startup and adds a new field in the resulting JSON, informing the caller
that the commands are deprecated and may become unavailable at any time.
