This implements caching of ancestor state to each mempool entry, similar to
descendant tracking, but also including caching sigops-with-ancestors (as that
metric will be helpful to future code that implements better transaction
selection in CreatenewBlock).
The work limit served to prevent the descendant walking algorithm from doing
too much work by marking the parent transaction as dirty. However to implement
ancestor tracking, it's not possible to similarly mark those descendant
transactions as dirty without having to calculate them to begin with.
This commit removes the work limit altogether. With appropriate
chain limits (-limitdescendantcount) the concern about doing too much
work inside this function should be mitigated.
While trying to find a black/white version of the Bitcoin
logo for the organization I noticed the about.png is not
entirely black - it has some reflection. Remove this to make
it the same as other icons.
Also ran the icons through `contrib/devtools/optimize-pngs.py`,
so `chevron.png` was optimized too.
It looks like, TorController::disconnected_cb(TorControlConnection&
conn) gets called multiple times which results in multiple event_new().
Avoid this by creating the event only once in the constructore, and
deleting it only once in the destructor (thanks to Cory Fields for the
idea).
Replaces the fix by Jonas Schnelli in #7610, see discussion there.
Continues "Make logging for validation optional" from #6519.
The idea there was to remove all ERROR logging of rejected transaction,
and move it to one message in the class 'mempoolrej' which logs the
state message (and debug info). The superfluous ERRORs in the log
"terrify" users, see for example issue #5794.
Unfortunately a lot of new logging was introduced in #6871 (RBF) and
#7287 (misc refactoring). This pull updates that new code.
Implements #7442 by adding an option `-stdin` which reads
additional arguments from stdin, one per line.
For example
```bash
echo -e "mysecretcode\n120" | src/bitcoin-cli -stdin walletpassphrase
echo -e "walletpassphrase\nmysecretcode\n120" | src/bitcoin-cli -stdin
```
BerkeleyDB dump files have key and value lines indented.
The salvage code passes these to ParseHex as-is.
Check this in the tests (should just pass with current code).
Check for EOF before every getline, and warn when reading gets to EOF
before the end of the data.
Stricter error checking could shed more light on issues such as #7463
and #7379.
- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112)
<nSequence> CHECKSEQUENCEVERIFY -> <nSequence>
- Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block.
- Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence()
- Add bitwise AND operator to CScriptNum
- Enable CHECKSEQUENCEVERIFY as a standard script verify flag
- Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.
