P2P test design notes
|
||||
---------------------
|
||||
|
||||
## Mininode
|
||||
|
||||
* ```mininode.py``` contains all the definitions for objects that pass
|
||||
over the network (```CBlock```, ```CTransaction```, etc, along with the network-level
|
||||
wrappers for them, ```msg_block```, ```msg_tx```, etc).
|
||||
|
||||
* P2P tests have two threads. One thread handles all network communication
|
||||
with the bitcoind(s) being tested (using python's asyncore package); the other
|
||||
implements the test logic.
|
||||
|
||||
* ```NodeConn``` is the class used to connect to a bitcoind. If you implement
|
||||
a callback class that derives from ```NodeConnCB``` and pass that to the
|
||||
```NodeConn``` object, your code will receive the appropriate callbacks when
|
||||
events of interest arrive. NOTE: be sure to call
|
||||
```self.create_callback_map()``` in your derived classes' ```__init__```
|
||||
function, so that the correct mappings are set up between p2p messages and your
|
||||
callback functions.
|
||||
|
||||
* You can pass the same handler to multiple ```NodeConn```'s if you like, or pass
|
||||
different ones to each -- whatever makes the most sense for your test.
|
||||
|
||||
* Call ```NetworkThread.start()``` after all ```NodeConn``` objects are created to
|
||||
start the networking thread. (Continue with the test logic in your existing
|
||||
thread.)
|
||||
|
||||
* RPC calls are available in p2p tests.
|
||||
|
||||
* Can be used to write free-form tests, where specific p2p-protocol behavior
|
||||
is tested. Examples: ```p2p-accept-block.py```, ```maxblocksinflight.py```.
|
||||
|
||||
## Comptool
|
||||
|
||||
* Testing framework for writing tests that compare the block/tx acceptance
|
||||
behavior of a bitcoind against 1 or more other bitcoind instances, or against
|
||||
known outcomes, or both.
|
||||
|
||||
* Set the ```num_nodes``` variable (defined in ```ComparisonTestFramework```) to start up
|
||||
1 or more nodes. If using 1 node, then ```--testbinary``` can be used as a command line
|
||||
option to change the bitcoind binary used by the test. If using 2 or more nodes,
|
||||
then ```--refbinary``` can be optionally used to change the bitcoind that will be used
|
||||
on nodes 2 and up.
|
||||
|
||||
* Implement a (generator) function called ```get_tests()``` which yields ```TestInstance```s.
|
||||
Each ```TestInstance``` consists of:
|
||||
- a list of ```[object, outcome, hash]``` entries
|
||||
* ```object``` is a ```CBlock```, ```CTransaction```, or
|
||||
```CBlockHeader```. ```CBlock```'s and ```CTransaction```'s are tested for
|
||||
acceptance. ```CBlockHeader```s can be used so that the test runner can deliver
|
||||
complete headers-chains when requested from the bitcoind, to allow writing
|
||||
tests where blocks can be delivered out of order but still processed by
|
||||
headers-first bitcoind's.
|
||||
* ```outcome``` is ```True```, ```False```, or ```None```. If ```True```
|
||||
or ```False```, the tip is compared with the expected tip -- either the
|
||||
block passed in, or the hash specified as the optional 3rd entry. If
|
||||
```None``` is specified, then the test will compare all the bitcoind's
|
||||
being tested to see if they all agree on what the best tip is.
|
||||
* ```hash``` is the block hash of the tip to compare against. Optional to
|
||||
specify; if left out then the hash of the block passed in will be used as
|
||||
the expected tip. This allows for specifying an expected tip while testing
|
||||
the handling of either invalid blocks or blocks delivered out of order,
|
||||
which complete a longer chain.
|
||||
- ```sync_every_block```: ```True/False```. If ```False```, then all blocks
|
||||
are inv'ed together, and the test runner waits until the node receives the
|
||||
last one, and tests only the last block for tip acceptance using the
|
||||
outcome and specified tip. If ```True```, then each block is tested in
|
||||
sequence and synced (this is slower when processing many blocks).
|
||||
- ```sync_every_transaction```: ```True/False```. Analogous to
|
||||
```sync_every_block```, except if the outcome on the last tx is "None",
|
||||
then the contents of the entire mempool are compared across all bitcoind
|
||||
connections. If ```True``` or ```False```, then only the last tx's
|
||||
acceptance is tested against the given outcome.
|
||||
|
||||
* For examples of tests written in this framework, see
|
||||
```invalidblockrequest.py``` and ```p2p-fullblocktest.py```.
