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.
