Suhas Daftuar 50262d8953 Allow block announcements with headers
This replaces using inv messages to announce new blocks, when a peer requests
(via the new "sendheaders" message) that blocks be announced with headers
instead of inv's.

Since headers-first was introduced, peers send getheaders messages in response
to an inv, which requires generating a block locator that is large compared to
the size of the header being requested, and requires an extra round-trip before
a reorg can be relayed.  Save time by tracking headers that a peer is likely to
know about, and send a headers chain that would connect to a peer's known
headers, unless the chain would be too big, in which case we revert to sending
an inv instead.

Based off of @sipa's commit to announce all blocks in a reorg via inv,
which has been squashed into this commit.

The pull-tester folder contains a script to call multiple tests from the rpc-tests folder.

Every pull request to the bitcoin repository is built and run through the regression test suite. You can also run all or only individual tests locally.

Running tests

You can run any single test by calling qa/pull-tester/rpc-tests.py <testname>.

Or you can run any combination of tests by calling qa/pull-tester/rpc-tests.py <testname1> <testname2> <testname3> ...

Run the regression test suite with qa/pull-tester/rpc-tests.py

Run all possible tests with qa/pull-tester/rpc-tests.py -extended

Possible options:

  -h, --help            show this help message and exit
  --nocleanup           Leave bitcoinds and test.* datadir on exit or error
  --noshutdown          Don't stop bitcoinds after the test execution
  --srcdir=SRCDIR       Source directory containing bitcoind/bitcoin-cli
                        (default: ../../src)
  --tmpdir=TMPDIR       Root directory for datadirs
  --tracerpc            Print out all RPC calls as they are made
  --coveragedir=COVERAGEDIR
                        Write tested RPC commands into this directory

If you set the environment variable PYTHON_DEBUG=1 you will get some debug output (example: PYTHON_DEBUG=1 qa/pull-tester/rpc-tests.py wallet).

A 200-block -regtest blockchain and wallets for four nodes is created the first time a regression test is run and is stored in the cache/ directory. Each node has 25 mature blocks (25*50=1250 BTC) in its wallet.

After the first run, the cache/ blockchain and wallets are copied into a temporary directory and used as the initial test state.

If you get into a bad state, you should be able to recover with:

rm -rf cache
killall bitcoind

Writing tests

You are encouraged to write tests for new or existing features. Further information about the test framework and individual rpc tests is found in qa/rpc-tests.
