If the mantissas of two non-native amounts differ by less than 10, then
subtracting them leaves a result of zero. This can cause situations
where `a>b`, yet `a-b == 0`.
One consequence of this is unfunded offers were incorrectly left in
order books. The code would check if the offer would be
consumed (`amount in offer > amount needed`), assume it wouldn't be,
yet when `amount needed` was subtracted from `amount in offer` the
result was zero and the offer was unfunded. This unfunded offer
incorrectly remained on the order book.
This patch fixes this bug.
* Make HTTP(S) requests on websocket ports reply with Status page
* Fix isWebsocketUpgrade to compare case insensitive
* Make websocket upgrades with no websocket protocols configured report error
* Create unit test for unauthorized requests and the status page
Add basic ledger_request validation tests to replace the existing
ledger.js tests. Provide tests that trigger some error conditions
in RPC handling code.
The XRPEndpointStep bypassed the logic in deferred credits and
incorrectly counted funds acquired during a payment as available for
use in the payment. It also incorrectly used the current ownerCount when
calculating the reserve instead of the owner count as it was at the
beginning of the payment (reducing the owner count is analogous to
acquiring funds during a payment.)
All cases that still used the old RPF code now use new-style pathfinding.
This includes unit tests, RPF requests with a ledger specified, and RPF
requests in standalone mode.
A recent commit (0d0227e744) broke the
parser for the rpc command `account_lines` such that an empty
string ("") was no longer required for the second parameter. This commit
fixes that bug.
Note the empty peer field string requirement only applies to the rippled
command line. It can be comitted with a ledger via HTTP or WebSocket.
Create SetRegularKey test to replace existing js test. Copy and simplify
some existing test logic from Env_test.cpp and MultiSign.test.cpp. Add
coverage for tfUniversalMask tx flag error case.
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.
* If an account has any transactions in the transaction queue, submitting
a transaction that covers the differences to the open ledger fee level
for prior queued transactions plus itself will cause all those
transactions to be applied to the open ledger.
* tel failures in `TxQ::accept` will leave tx in the queue to retry later.
Payment channels permit off-ledger checkpoints of XRP payments flowing
in a single direction. A channel sequesters the owner's XRP in its own
ledger entry. The owner can authorize the recipient to claim up to a
give balance by giving the receiver a signed message (off-ledger). The
recipient can use this signed message to claim any unpaid balance while
the channel remains open. The owner can top off the line as needed. If
the channel has not paid out all its funds, the owner must wait out a
delay to close the channel to give the recipient a chance to supply any
claims. The recipient can close the channel at any time. Any transaction
that touches the channel after the expiration time will close the
channel. The total amount paid increases monotonically as newer claims
are issued. When the channel is closed any remaining balance is returned
to the owner. Channels are intended to permit intermittent off-ledger
settlement of ILP trust lines as balances get substantial. For
bidirectional channels, a payment channel can be used in each direction.
* Updates both server_info and server_state
* Adds "load_factor_server", which reports the server-only portion of the
load (if appropriate) so clients can decide an appropriate fee to pay if
the open ledger fee is higher than they're willing to pay.
=== Release Notes ===
==== Updated Features ====
Both `server_info` and `server_state` report the escalated ledger fee in
the `load_factor` result parameter. If appropriate, `load_factor_server`
reports the server-only portion of the load so clients can submit a fee
between those two values to get into the queue.
* Account-related queue stats (RIPD-1205). Boolean "queue" parameter to
account_info only if requesting the open ledger.
* Account for the TxQ when autofilling sequence in sign-and-submit (RIPD-1206)
* Tweak TxQ::accept edge case when choosing which tx to try next.
* Labels for experimental "x_" submit parameters use correct separator.
=== Release Notes ===
==== New features ====
When requesting `account_info` for the open ledger, include the `queue :
true` to get extra information about any queued transactions for this
account. (RIPD-1205).
==== Bug fixes ====
When using sign-and-submit mode to autofill a transaction's sequence
number, the logic will not reuse a sequence number that is in the queue
for this account. (RIPD-1206).
Labels for experimental "x_queue_okay" and "x_assume_tx" parameters to
`sign` and `submit` updated to use correct separator.
