This converts the transaction type and version to scoped enum, giving
type safety and making the tx type assignment less error prone because
there is no implicit conversion or comparison with raw integers that has
to be worried about.
This ends up converting any use of `cryptonote::transaction::type_xyz`
to `cryptonote::transaction::txtype::xyz`. For version, names like
`transaction::version_v4` become `cryptonote::txversion::v4_tx_types`.
This also allows/includes various other simplifications related to or
enabled by this change:
- handle `is_deregister` dynamically in serialization code (setting
`type::standard` or `type::deregister` rather than using a
version-determined union)
- `get_type()` is no longer needed with the above change: it is now
much simpler to directly access `type` which will always have the
correct value (even for v2 or v3 transaction types). And though there
was an assertion on the enum value, `get_type()` was being used only
sporadically: many places accessed `.type` directly.
- the old unscoped enum didn't have a type but was assumed castable
to/from `uint16_t`, which technically meant there was potential
undefined behaviour when deserializing any type values >= 8.
- tx type range checks weren't being done in all serialization paths;
they are now. Because `get_type()` was not used everywhere (lots of
places simply accessed `.type` directory) these might not have been
caught.
- `set_type()` is not needed; it was only being used in a single place
(wallet2.cpp) and only for v4 txes, so the version protection code was
never doing anything.
- added a std::ostream << operator for the enum types so that they can be
output with `<< tx_type <<` rather than needing to wrap it in
`type_to_string(tx_type)` everywhere. For the versions, you get the
annotated version string (e.g. 4_tx_types) rather than just the number
4.
* Initial updates to allow syncing of checkpoints in protocol_handler
* Handle checkpoints in prepare_handle_incoming_blocks
* Debug changes for testing, cancel changes later
* Add checkpoint pruning code
* Reduce DB checkpoint accesses, sync votes for up to 60 blocks
* Remove duplicate lifetime variable
* Move parsing checkpoints to above early return for consistency
* Various integration test fixes
- Don't try participate in quorums at startup if you are not a service node
- Add lock for when potentially writing to the DB
- Pre-existing batch can be open whilst updating checkpoint so can't use
DB guards
- Temporarily emit the ban message using msgwriter instead of logs
* Integration mode bug fixes
- Always deserialize empty quorums so get_testing_quorum only fails when
an actual critical error has occurred
- Cache the last culled height so we don't needlessly query the DB over
the same heights trying to delete already-deleted checkpoints
- Submit votes when new blocks arrive for more reliable vote
transportation
* Undo debug changes for testing
* Update incorrect DB message and stale comment
* RPC endpoint for requesting random snodes
* optionally get fully funded service nodes only
* static random device
* explicitly initialize fields
* better handle default parameters
* add more comments to aid doc generator
* Use the precalculated public key when trying to gen key images
Fixes failure to export key image bug and several other spending proof
mechanisms, where if you receive Loki from multiple outputs in the same
transaction, encrypted using multiple public keys- we don't fail out
prematurely by only trying the first public key.
* Rewrite find_tx_extra_field_by_typte
- Don't try participate in quorums at startup if you are not a service node
- Add lock for when potentially writing to the DB
- Pre-existing batch can be open whilst updating checkpoint so can't use
DB guards
- Temporarily emit the ban message using msgwriter instead of logs
* Add debug_mine_singular_block to mine one block at a time for integration tests
* Add workaround for mining thread modifying main thread state causing lock
* Change debug_mine_singular blocks to debug_mine_n_blocks
* Incorporate service node ip address into uptime proofs; expose them using rpc
* Check that storage server port is specified in service-node mode
* Remove problematic const, rename argument name for storage port, update comments
* Validate ip address when receive uptime proof
* Better argument names and descriptions
* Initial updates to allow syncing of checkpoints in protocol_handler
* Handle checkpoints in prepare_handle_incoming_blocks
* Parse checkpoints sent by peer
* Fix rebase to dev referencing no longer valid argument
* Unify checkpointing and uptime quorums
* Begin making checkpoints cull old votes/checkpoints
* Begin rehaul of service node code out of core, to assist checkpoints
* Begin overhaul of votes to move resposibility into quorum_cop
* Update testing suite to work with the new system
* Remove vote culling from checkpoints and into voting_pool
* Fix bugs making integration deregistration fail
* Votes don't always specify an index in the validators
* Update tests for validator index member change
* Rename deregister to voting, fix subtle hashing bug
Update the deregister hash derivation to use uint32_t as originally set
not uint64_t otherwise this affects the result and produces different
results.
* Remove un-needed nettype from vote pool
* PR review, use <algorithms>
* Rename uptime_deregister/uptime quorums to just deregister quorums
* Remove unused add_deregister_vote, move side effect out of macro
