generate test-vectors based on tests from chain-validation project (#181) * Read a subset of filecoin state over the full node API * wip * import export wip * extract actors from message * generate car for any state * library for providing a pruned statetree * test vector schema draft + example 'message' class test vector. * message => messages test vector class. * fixup * wip * use lb.NewBlockstore with ID * fixup lotus-soup, and generate * fix deals * magic params * work on schema / export of test vector * fixup * wip deserialise state tree * pass at building a test case from a message * progress loading / serializing * recreation of ipld nodes * generation of vector creates json * kick off tvx tool. * wip * wip * retain init actor state. * initial test with printed out state * remove testing.T, but keep require and assert libraries * wip refactor state tree plucking. * simplified * removed factories * remove builder.Build ; remove interface - use concrete iface * comment out validateState * remove Validator * remove TestDriverBuilder * remove client * remove box * remove gen * remove factories * remove KeyManager interfafce * moved stuff around * remove ValidationConfig * extract randomness * extract config and key_manager * extract statewrapper * extract applier * rename factories to various * flatten chain-validation package * initial marshal of test vector * do not require schema package * fixup * run all messages tests * better names * run all messages tests * remove Indent setting from JSON encoder for now * refactor, and actually running successfully ;-) * remove irrelevant files; rename extract-msg command. * remove root CID from state_tree object in schema. * add tvx/lotus package; adjust .gitignore. * tidy up command flag management. * add comment. * remove validateState and trackState * remove xerrors * remove NewVM * remove commented out RootCID sets * enable more tests * add all `message_application` tests * delete all.json * update Message struct * fix message serialization * support multiple messages * gofmt * remove custom Message and SignedMessage types * update tests with gzip and adhere to new schema for compressed CAR * improved iface for Marshal * update Validation * remove test-suites and utils * better names for chain. methods * go mod tidy * remove top-level dummyT Co-authored-by: Will Scott <will@cypherpunk.email> Co-authored-by: Raúl Kripalani <raul@protocol.ai>
