* opnode: Reconcile epochs and handle reorgs (#309)

* opnode: Switch to uint64 in FindL2Heads function

* opnode: Properly initialize state loop

This properly sets the L1 head, L2 Head, and L2 Unsafe Head during
`state.Start()` in normal operation and when the current L1 head
has not reached the L1 genesis.

* opnode: Rename output functions

The old names where not good.
In addition, this standardizes the order of arguements and extends the
returns. The returns are not fully used, but will be.

* opnode: Add sanity check to L1 window in insertEpoch

This make sure that the L1 window starts at the correct block.

* opnode: Split out loop

Now each action occurs in a seperate function. The state loop is
still responsible for sequencing follow-up actions, but is not
responsible for setting state.

* opnode: Better name for batch prepare functions

This name indicates that it provides missing batches.

* opnode: Verify epochs as sequencer

Sequencers now verify epochs and will reorg if they see that verified
epochs do not match what they created.

* opnode: Mute driver test

* opnode: Set L2 Geth forkchoice on reorg

This is required to handle L1 reorgs (rather than just missing
batches).

* opnode: Bump op-geth version

Needed to fix a bug where the L2 geth node was missing the `mint` field
in deposit transactions when returning them over the JSON RPC server.

* opnode: Don't incorrectly advance safehead

There is some L2 block that is possible to fully derive from L1;
however, if it is ahead of the current state's safe head, do not
advance the current state's safehead because the chain has not
been verified up to that point.

* deps: install entire goddamn monorepo using forge.

I needed the trie contracts over here, so now the whole monorepo
is a submodule of the specs repo. Happy now @norswap?

Why, you ask, did I do this rather than the alternatives available to
me?
1. Copying and pasting is gross.
2. `yarn add` would have installed a smaller dep, but it's also gross.
3. git submodules, while also gross in their own right, is at least
   consistent with how we're currently handling other dependencies, so
   I went with that.

* Update predeploy addresses

The new predeploy addresses are incremented by 1 in order to avoid
conflicts with the system addresses.

* tests: Add tests for batch requests when the parent request fails

This test makes sure that we do not retry when the parent request fails. We don't, but it wasn't immediately clear.

I also removed a duplicate assertion lib since we're using `testify` everywhere else.

* opnode: Don't start sequencing blocks until past the L1 genesis (#325)

This has to be reverted to ensure that the sequencer starts producing
blocks at the same location as the verifier. Sometimes the previous
code would cause reorgs on the sequencer (expected), and sometimes
it would cause a chain split (unexpected and unexplained as of
writing this commit message 4/6/22).

* opnode: update to latest L2 geth

* readme: fix typos and break lines (#327)

* Update ref optimistic geth image (#328)

* ci: Improve timestamp management in devnet (#329)

This change sets timestamps to the current timestamp on fresh devnet deploys. This avoids the devnet having to fill in a bunch of blocks on startup. The timestamp is preserved between runs; `make devnet-clean` will erase the timestamp data if you want to start anew.

* contracts: Move withdrawal logic into abstract contract

* contracts: Move withdrawal hashing logic into library

* contracts: Update .gas-snapshot

* contracts: silence compiler warnings

* feat: expose debug http api (#334)

* opnode: Use l2 safe head instead of l2 head

Epochs should be inserted on top of the L2 Safe Head, not the
unsafe head. This was causing problems when a reorg would occur
and the node would start building in the wrong spot.

* opnode: Clear l1WindowBuf on insertEpoch failure

This is done to handle the case that the l1WindowBuf does not start
in the correct location (direct check is difficult with context).
The correct response to that is to clear the window and initialize
it from the correct block.

* hardhat: clean up the hardhat deposit task

* fix: oe => optimism (#338)

* opnode: Rework state test to build on safe head

This also got caught up in the unsafe/safe head confusion.

Solidity ABI only looks at the function name and types, but does not
consider the name of the function parameters.

* rollup: fix address of the L1 Block Attributes contracts

* opnode: Fix bug in block creation (#345)

The NoTxPool flag was incorrectly set to falses in the InsertEpoch
function.

* opnode: Don't allow arbitrary mints (#346)

The ordering of `mint, value` was switched to be `value, mint`
when parsing emitted logs. This allows users to control their
mint rather than using `msg.value` which is being fed directly
into the event.

Thanks to Mofi (Inphi) for finding this.

* opnode: Fix possible panic in sequencer batch creation (#342)

Previously we assumed that every deposit would be included in the L2
block. However, the L2 execution engine removes depoists that are
not valid. As such the number of deposits submitted to the execution
engine could be greater than the number of transactions returned
causing a panic.

This fixes the issue by counting the number of deposits returned
and using that to slice the payload transactions for batch submission.
(Deposits are not submitted in batches and instead read directly from L1).

This also does more sanity checks on the transactions included in the L2
block and rejects blocks with invalid deposit tx configurations. This is
done prior to marking the payload canonical with the FCU.

* opnode: Test Utilities (#319)

* opnode: Deduplicate fake chain source

The fake chain source is an easy way to create and L1 and L2 chains from
a simple string defition. There were previously two implementations and
now they are in a shared testutils package.

* opnode: Dedicated wait functions

This deduplicates wait for transactions on L1 and L2.

* opnode: New e2e test system

This splits out the initialization from the actual tests to eanble
multiple e2e tests. Some of the config is still not as dedpulicated
as I would like, but it is more centralized than it previously was.

Aims to move the setup from the tests and enable easier e2e tests.

* opnode: Silence FindSyncStartTest

* opnode: Add test for missing batches

This ensures the the sequencer follows the chain that is derived
from L1 rather than what it sequenced in the case that it misses
batch submission.

* opnode: Pull out system config to default cfg

This reduces duplication and makes tests easier to understand.

* opnode: Address PR comments

* opnode: Reduce flakiness in missing batch test

The proper way to do this is to wait for a safe block, but the API
is not yet ready for that.

* Fix sync-start bug + improve sync-start comments (#355)

Fix bug (L1 origin head with non-canonical ancestors)

This happened in the scenario where `l2ahead == true` (L1 origin of start is
ahead of know L1 head) and `start` had an ancestor whose L1 origin was known not
to be canonical.

Example: L1 head is at block X. `start` has an L1 origin with number X + 1 but its
parent L2 block has an L1 origin with number X whose blockhash is not canonical.
In this case, the algorithm still returned `start` as the unsafe L1 head, which is
incorrect.

This also touches a bunch of comments to generally improve understanbility.

* opnode,l2os: Better lifecycle management (#358)

* opnode: Properly wait for limit client to shut down

We removed closing the semaphore channel because it would cause a
panic as we did not wait for in flight requests (and new requests)
to stop before closing the L1 source.

* l2os: Change shutdown procedure

This is now blocking, but also reuces the amount of error logs.

* opnode: Shutdown rollup nodes before clients/geth nodes

Also actually shuts down the L2 clients in the rollup node.

* opnode: Properly shut everything down

* style: clean up and comments for state.go (#356)

* opnode: Parameterize deposit contract address (#361)

The contract can be deployed to any address. It is set in the
rollup config file.

* opnode/test: Add reverted deposit with mint test

* fix(ci): use Foundry GHA (#367)

Nightly Foundry releases are kept around for 3 days. This means we cannot be pinning the download link on CI to a specific commit.

Instead, we use the Foundry Toolchain GHA which always uses the latest nightly version.

* opnode/test: check nonce increment in deposit fail

* integration-tests: End-to-end withdrawal test (#362)

Includes several fixes to make this work:

- Modifies the devnet to deploy the L1 contracts rather than include them in genesis.
- Changes the deployment of L2OutputOracle to support a custom start timestamp.
- Updates UserDeposits to properly filter out non-TransactionDeposited events.
- Updates the L2 output submitter to post the current L1 block with each output rather than the L2 checkpoint block
- Updates the opnode API to allow all vhosts and CORS domains.

* go.mod: bump l2geth version

* opnode: Update and deploy contracts (#360)

This is rather than hardcoding the contract bytecode. It slows down the e2e
tests (by having to wait 1 L1 block for contracts to be ready), but it
is more accurate to what occurs (and is now required as we initialize
actions).

This also pins the L2OutputOracle to v0.8.10 of solidity.

We ran into this on the monorepo too. Alpine 3.14 removes the `faccessat2` syscall. This caused "operation not permitted" errors while building. Upgrading Circle's Docker version fixes this. See https://wiki.alpinelinux.org/wiki/Release_Notes_for_Alpine_3.14.0#faccessat2 for more information.

* contracts: reuse code (#380)

* contracts: reuse the library to compute withdrawal hash

The `WithdrawalVerifier` has a method to compute the
withdrawal hash as part of a library. Use this library
in both the L1 and L2 contracts so that code can be reused.

* contracts: gas snapshot

* opnode: Better parsing of the TransactionDepositedEvent (#382)

This now asserts that the offset for the bytes field of the event
is the correct value rather than the previous incorrect check. This
check is not fully necessary, but good to have to validate that the
data is well formed.

* Makefile,ops: docker compose up instead of run to make devnet-down work, and fix makefile label (#385)

* opnode: Do not drop all deposits on parsing error (#383)

* Change deposit gasLimit from uint256 to uint64

This prevents the user from setting a gas limit that the rollup node
is not able to parse.

* opnode: Do not drop all deposits on parsing error

Only drop the affected deposit. This does mean loss of funds, but
this is also a case that should never happen. In addition, halting
the chain means that while funds are safe, we are exposed to a
denial of service attack if it would be possible to cause a parsing
error from the deposit feed contract.

* opnode/test: Provide flag to access geth logs (#389)

This enables a more verbose output without having to modify the test
itself. Provide the flag `gethlogs` to see logs from geth.

* opnode: Fix L1 Info Transactions

There are three issues being fixed:
1. Set the `from` field to the correct magic value (found by ToB)
2. Update the L2 EE to provide gas to deposits. Otherwise the
   deposit transactions immediatley out of gas and fail.
3. Update the manual ABI encoding to match what solidity expects.
   The previous version was similar to packed encodeding, but as
   such could not be parsed by solidity.

This also includes a regression test that the parsing of the L1 info
tx and what is recorded in the state for each block matches.

* contracts: import messengers (#393)

* chore: copy L1 and L2 Messengers from Monorepo

* test: Add Messenger test files

Monorepo test cases are copied in as comments from the monorepo ts tests.

* chore: Add OZ upgradable contracts

New remappings were also added in order to avoid excessively

long import statements.

* chore: Importe OZ and OP contracts as node_modules

Necessary because hardhat does not support remappings!?!

y u no?

* refactor: Remove replayMessage()

We no longer need this function as it was only necessary when the CTC
a maximum gas limit per epoch concept. In order to remove the function
I had to copy in the L1xDM interface rather than import from the
node_modules.

* chore: Remove unused files

The ts test file is made redundant by an itest in the itest package.
The sol test file was not being used for anything

* refactor: Remove Address Manager and Resolver

Instead the CTC and SCC are state variables

* refactor: Replace CTC with OptimismPortal

* refactor: Remove SCC

We don't need to replace it with the L2OutputOracle in the L1xDM,
because the verification is now done in the OptimismPortal itself.

Also adds a lib with constant values for new bedrock predeploys.

* chore: Make functions external, and reorder for CEI

For whatever reason a bunch of functions on the messengers were public,
when they could have been external. I fixed that, and removed the
slither annotations. Where possible (in the sendMessage functions), I
also reordered the events and calls to respect
Checks-Effects-Interactions. There was no risk previously, but this
removes any question, and quiets slither.

Move helpers/index into utils.ts, and add other files which are exported in

the new index.ts.

create `OVM_ETH` on L2.

Use `abi.encode` instead of `abi.encodePacked` to ensure
a constant serialization. `abi.encode` will be sure to
pad the value to its size while `abi.encodePacked` will not
when operating on integers. There should not have been a bug here
because it was being called with a `bytes32`, which should
always be 32 bytes when returned from `abi.encodePacked`.

* opnode: refactor RPC server / config, prototype batch serving

* feat: enforce size contraints on batch bundles

This algorithm is modeled mostly off the one used in the existing batch
submitter. The additional complexity enables us to configure a min and
max value such that max - min < max_l2_tx_size. Applied strictly,
submitting a large L2 tx would cause the batch construct to halt, since
the batch constructed without including batch `i` can be under the min,
while including batch `i` resulting in exceeding the maximum. The
additional complexity in the pruning algorithm is used to identify this
case and submit an undersized batch when it cannot be avoided. In the
general case, however, this strategy increases our expected
profitibability since the average batch size is closer to the desired
maximum.

* feat: add BundleBuilder helper class

* fix: typo in l2os config docs

* feat: add GetBatchBundle method to rollupclient.RollupClient

* feat: simplify l2os rollupclient init

* feat: reduce BSS poll interval

The current setup assumes the batches are submitted very soon after the
block is created on L2. Increasing the poll interval ensures that we
discover and publish new batches in response. Without modifying this
value, the subsequent changes will still fail even though the code is
correct.

* feat: add sequencer history db

* feat: add sequencer BSS driver to submit batches

* opnode: Avoid busy-waiting while L2 head is behind L1

In the state select loop, we immediately request for new L2 blocks whenever
the latest L1 origin is behind L1. This can be an issue as we attempt to
re-request the latest L2 block without any delay. This is a DoS hazard
particularly when an L2 block cannot be retrieved because either the `L1Chain`
or `L2Chain` backends have errors.

Another problem with this is that other, more useful events in the state
select loop, are less likely to be scheduled by the Go runtime due to
the busy-wait.

Adding a small delay, before calling `reql2BlockCreation` of about 10ms
should be enough to prevent issues.

* opnode: Fix Incorrect error handling when creating an L2 block (#391)

* opnode: Fix Incorrect error handling when creating an L2 block

This is an issue ToB identified (issue #8). What happens is that
the ethereum.NotFound error would never be returned, but in general

going.

* contracts: add backup logic for deposits

Introduces backup logic for deposits that prevents users from
accidentally making bad deposits. Deposits that don't complete
successfully will be returned back to the layer where the deposits were
made.

* contracts: add base gas to sent messages

Introduces base gas to the CrossDomainMessenger's sendMessage function.
Base gas is used to guarantee that all messages sent between messengers
will at the very least be able to store the message hash on the other
chain and therefore be replayable. Base gas scales dynamically with the
size of the message.

* contracts: use clearer message encoding

Uses the clearer abi.encodeWithSelector within CrossDomainMessenger's
sendMessage function. Doing this makes it much more apparent that a call
to the relayMessage function is being triggered.

* contracts: add L1BlockNumber predeploy

Re-introduces the L1BlockNumber predeployed contract for backwards
compatibility with the previous OVM_L1BlockNumber contract.

* Fix SRI on stateviz (#440)

* Fix L2 Output Timestamps (#416)

There was an off by one error in the L2 Output Oracle contract in the timestamp to
block number conversion. In addition, the L2 Output Submitter (op proposer) did
not recognize that there was a mismatch between the timestamp/block number in
the header and the timestamp/block number from the contract.

This bug causes problems when trying to do withdrawals.


Fixes ENG-2128

* opnode: Withdrawal E2E test in go (#423)

This does the following:
- Adds withdrawal utilities (to opnode/withdrawals)
- Adds an end to end test in go of withdrawals
- Adds the L2 withdrawer contract
- Updates to a newer version of reference-go-ethereum


Fixes ENG-2202

* Adopt go.work, rename modules to prep for monorepo (#441)
Co-Authored-By: Matthew Slipper <me@matthewslipper.com>
Co-authored-by: protolambda <proto@protolambda.com>

* remove git submodules

* optimistic-specs: monorepo merge, mv into protocol dir

* bedrock contracts dependencies

* monorepo merge: fix Go env

* monorepo merge: move contracts-bedrock into non-Lerna package

* monorepo merge: bring back CI

Known issues:

- There are broken links that `lychee` picks up on. These still need to be updated.
- Slither returns errors, both here and in `optimistic-specs`.
- `go-bip39` was updated to a newer version. The newer version broke a `bss-core` test, which had to be fixed.
- Forge is not compatible with Lerna. As a result, the `contracts-bedrock` package had to be moved out of the `packages` hierarchy.
- The devnet itests don't work because the Go modules aren't on the default branch. We need to decide if we merge to develop, or stay on a feature branch before fixing this.

* outline bedrock dirs, rm stale protocol repo files (#2562)

* monorepo merge: re-run yarn
