"startingpriority" and "currentpriority" are no longer returned in the JSON information about a mempool entry. This affects getmempoolancestors, getmempooldescendants, getmempooolentry, and getrawmempool.
Remove -limitfreerelay and always enforce minRelayTxFee in the mempool (except from disconnected blocks)
Remove -relaypriority, the option was only used for the ability to allow free transactions to be relayed regardless of their priority. Both notions no longer apply.
Previously if an existing watch only key was reimported with a new timestamp,
the new timestamp would not be saved in the key metadata, and would not be used
to update the wallet nTimeFirstKey value (which could cause rescanning to start
at the wrong point and miss transactions).
Issue was pointed out by Jonas Schnelli <dev@jonasschnelli.ch> in
https://github.com/bitcoin/bitcoin/pull/9108#issuecomment-279715550
If InitBlockIndex fails, then it will segfault later. Same for the later
ActivateBestChain. BOOST_REQUIRE the result, so that an error will be
reported and the test case aborted.
Change ScanForWalletTransactions return value so it is possible to distinguish
scans that skip reading every block (due to the nTimeFirstKey optimization)
from scans that fail while reading the chainActive.Tip() block. Return value is
now non-null in the non-failing case.
This change doesn't affect any user-visible behavior, it is only an internal
API improvement. The only code currently using the ScanForWalletTransactions
return value is in importmulti, and importmulti always calls
ScanForWalletTransactions with a pindex pointing to the first block in
chainActive whose block time is >= (nLowestTimestamp - 7200), while
ScanForWalletTransactions would only return null without reading blocks when
pindex and every block after it had a block time < (nTimeFirstKey - 7200).
These conditions could never happen at the same time because nTimeFirstKey <=
nLowestTimestamp.
I'm planning to make a more substantial API improvement in the future (making
ScanForWalletTransactions private and exposing a higher level rescan method to
RPC code), but Matt Corallo <git@bluematt.me> pointed out this odd behavior
introduced by e2e2f4c "Return errors from importmulti if complete rescans are
not successful" yesterday, so I'm following up now to get rid of badness
introduced by that merge.
Prior to this commit pindexRescan was initialized to a chainActive.Tip().
However, the value of pindexRescan set at time of initialization was never
read before pindexRescan was being set to either chainActive.Genesis()
(case 1), FindForkInGlobalIndex(chainActive, locator) (case 2) or
chainActive.Genesis() (case 3). Thus, the initialization was redundant.
This commit a.) removes the redundant initialization and b.) simplifies
this logic so that pindexRescan is initialized to chainActive.Genesis()
(case 1 and 3), and set to FindForkInGlobalIndex(chainActive, locator)
(case 2) as needed.
In the case that the branch ...
if (itInFlight != mapBlocksInFlight.end() && itInFlight->second.first == nodeid) {
... is taken, there was prior to this commit an implicit assumption that
MarkBlockAsInFlight(...) was being called with its fifth and optional
argument (pit) being present (and non-NULL).
This removes the option from the wallet to not pay a fee on "small"
transactions which spend "old" inputs.
This code is no longer worth keeping around, as almost all miners
prefer not to include transactions which pay no fee at all.
Use of `sprintf` is seen as a red flag as many of its uses are insecure.
OpenBSD warns about it while compiling, and some modern platforms, e.g.
[cloudlibc from cloudabi](https://github.com/NuxiNL/cloudlibc) don't
even provide it anymore.
Although our uses of these functions are secure, it can't hurt to
replace them anyway. There are only 3 occurences left, all in the
tests.
