Ubuntu 16.04 "xenial xerus" does not come with Python 2.x by default.
It is possible to install a python-2.7 package, but this has its own
problem: no `python` or `python2` symlink (see #7717).
This fixes the following scripts to work with python 3:
- `make check` (bctest,py, bitcoin-util-test.py)
- `make translate` (extract_strings_qt.py)
- `make symbols-check` (symbol-check.py)
- `make security-check` (security-check.py)
Explicitly call the python commands using $(PYTHON) instead
of relying on the interpreter line at the top of the scripts.
The build date does only makes sense for custom/self-compiled bitcoin-core versions because we are using static build-dates for our deterministic release builds.
Having a quick option to get the current datadir is much more valuable for debug purposes.
The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.
Creates the generatetoaddress rpc which is virtually identical to the generate rpc except that it takes an argument for the address to mine to. It does not rely on wallet functionality.
The mining code shared by generate and generatetoaddress has been moved to another method to reduce duplication.
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.
