FIXES: #2847
* Transactions that are submitted with the fail_hard flag
and that result in any TER code besides tesSUCCESS shall
be neither queued nor held.
[FOLD] Keep tec results out of the open ledger when fail_hard:
* Improve TransactionStatus const correctness, and remove redundant
`local` check
* Check open ledger tx count in fail_hard tests
* Fix some wrapping
* Remove duplicate test
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.
This commit restructures the HTTP based protocol negotiation that `rippled`
executes and introduces support for negotiation of compression for peer
links which, if implemented, should result in significant bandwidth savings
for some server roles.
This commit also introduces the new `[network_id]` configuration option
that administrators can use to specify which network the server is part of
and intends to join. This makes it possible for servers from different
networks to drop the link early.
The changeset also improves the log messages generated when negotiation
of a peer link upgrade fails. In the past, no useful information would
be logged, making it more difficult for admins to troubleshoot errors.
This commit also fixes RIPD-237 and RIPD-451
When the Env::AppBundle constructor throws an exception
it still needs to run ~AppBundle(), otherwise the JobQueue
isn't properly shut down. Specifically the JobQueue
can destruct without waiting on outstanding jobs in the
queue.
This change ensures that if Env::AppBundle constructor
throws, Env::AppBundle::~AppBundle() runs.
This fixes the unit test crash exposed by PR #3047.
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.
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 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.
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 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.
Fixes: RIPD-1574
Alias beast address classes to the asio equivalents. Adjust users of
address classes accordingly. Fix resolver class so that it can support
ipv6 addresses. Make unit tests use ipv6 localhost network. Extend
endpoint peer message to support string endpoint
representations while also supporting the existing fields (both are
optional/repeated types). Expand test for Livecache and Endpoint.
Workaround some false positive ipaddr tests on windows (asio bug?)
Replaced usage of address::from_string(deprecated) with free function
make_address. Identified a remaining use of v4 address type and
replaced with the more appropriate IPEndpoint type (rpc_ip cmdline
option). Add CLI flag for using ipv4 with unit tests.
Release Notes
-------------
The optional rpc_port command line flag is deprecated. The rpc_ip
parameter now works as documented and accepts ip and port combined.
The lsfDepositAuth flag limits the AccountIDs that can deposit into
the account that has the flag set. The original design only
allowed deposits to complete if the account with the flag set also
signed the transaction that caused the deposit.
The DepositPreauth ledger type allows an account with the
lsfDepositAuth flag set to preauthorize additional accounts.
This preauthorization allows them to sign deposits as well. An
account can add DepositPreauth objects to the ledger (and remove
them as well) using the DepositPreauth transaction.
The six different ranges of TER codes are broken up into six
different enumerations. A template class allows subsets of
these enumerations to be aggregated. This technique allows
verification at compile time that no TEC codes are returned
before the signature is checked.
Conversion between TER instance and integer is provided by
named functions. This makes accidental conversion almost
impossible and makes type abuse easier to spot in the code
base.
The DepositAuth feature allows an account to require that
it signs for any funds that are deposited to the account.
For the time being this limits the account to accepting
only XRP, although there are plans to allow IOU payments
in the future.
The lsfDepositAuth protections are not extended to offers.
If an account creates an offer it is in effect saying, “I
will accept funds from anyone who takes this offer.”
Therefore, the typical user of the lsfDepositAuth flag
will choose never to create any offers. But they can if
they so choose.
The DepositAuth feature leaves a small gap in its
protections. An XRP payment is allowed to a destination
account with the lsfDepositAuth flag set if:
- The Destination XRP balance is less than or equal to
the base reserve and
- The value of the XRP Payment is less than or equal to
the base reserve.
This exception is intended to make it impossible for an
account to wedge itself by spending all of its XRP on fees
and leave itself unable to pay the fee to get more XRP.
This commit
- adds featureDepositAuth,
- adds the lsfDepositAuth flag,
- adds support for lsfDepositAuth in SetAccount.cpp
- adds support in Payment.cpp for rejecting payments that
don't meet the lsfDepositAuth requirements,
- adds unit tests for Payment transactions to an an account
with lsfDepositAuth set.
- adds Escrow and PayChan support for lsfDepositAuth along
with as unit tests.
* Can be exercised from the command line with json2
* Rewrite Env::do_rpc to call the same code as
rpc from the command line. This puts rpc
handling logic in one place.
* Remove composite helper functions
* Add set difference and Bitset/uint256 operators
* Convert tests to use new feature bitset set difference operator
In order to automatically run unit tests with newly created
amendments, prefer to start with jtx::supported_features() and
then subtract unwanted features.
These changes identified a few bugs that were hiding in
amendments. One of those bugs, in FlowCross, is not yet fixed.
By uncommenting the test in CrossingLimits_test.cpp you can see
failures relating to that bug. Since FlowCross is not yet
enabled on the network we can fix the bug at our convenience.
Both Tickets and SHAMapV2 have been around for a while and don't
look like they will be enabled on the network soon. So they are
removed from the supportedAmendments list. This prevents Env
from automatically testing with Tickets or SHAMapV2 enabled,
although testing with those features can still be explicitly
specified.
Drive-by cleanups:
o supportedAmendments() returns a const reference rather than
a fresh vector on each call.
o supportedAmendments() implementation moved from Amendments.cpp
to Feature.cpp. Amendments.cpp deleted.
o supportedAmendments() declared in Feature.h. All other
declarations deleted.
o preEnabledAmendments() removed, since it was empty and only
used in one place. It will be easy to re-add when it is needed.
o jtx::all_features_except() renamed to
jtx::supported_features_except(), which is more descriptive.
o jtx::all_amendments() renamed to jxt::supported_amendments()
o jtx::with_features() renamed to with_only_features()
o Env_test.cpp adjusted since featureTickets is no longer
automatically enabled for unit tests.
