Some downstream code (most notably PR https://github.com/UkoeHB/monero/pull/25) wants to use the src/serialization lib
for storing information persistently. When one builds classes/machines wishing to serialize containers, they must use
the `serializable_*` container classes. In this case, this makes the Seraphis library code unnecessarily tightly coupled
with the src/serialization code since one cannot swap out their type of storage format without major refactoring of class
field types. By serializing STL containers directly, we can abstract the serialization details away, making for much
cleaner design. Also small bonus side effect of this change is that STL containers with custom Comparators, Allocators,
and Hashers are serializable. `std::multimap` is added to the list of serializable containers.
Depends upon https://github.com/monero-project/monero/pull/9069.
Read more about k-anonymity [here](https://en.wikipedia.org/wiki/K-anonymity). We implement this feature in the monero daemon for transactions
by providing a "Txid Template", which is simply a txid with all but `num_matching_bits` bits zeroed out, and the number `num_matching_bits`. We add an operation to `BlockchainLMDB` called
`get_txids_loose` which takes a txid template and returns all txids in the database (chain and mempool) that satisfy that template. Thus, a client can
ask about a specific transaction from a daemon without revealing the exact transaction they are inquiring about. The client can control the statistical
chance that other TXIDs (besides the one in question) match the txid template sent to the daemon up to a power of 2. For example, if a client sets their `num_matching_bits`
to 5, then statistically any txid has a 1/(2^5) chance to match. With `num_matching_bits`=10, there is a 1/(2^10) chance, so on and so forth.

c4af33e Enforce restricted # pool txs served via RPC + optimize chunked reqs (j-berman)
9752116 wallet2, RPC: Optimize RPC calls for periodic refresh from 3 down to 1 call (rbrunner7)
- `/getblocks.bin` respects the `RESTRICTED_TX_COUNT` (=100) when
returning pool txs via a restricted RPC daemon.
- A restricted RPC daemon includes a max of `RESTRICTED_TX_COUNT` txs
in the `added_pool_txs` field, and returns any remaining pool hashes
in the `remaining_added_pool_txids` field. The client then requests
the remaining txs via `/gettransactions` in chunks.
- `/gettransactions` no longer does expensive no-ops for ALL pool txs
if the client requests a subset of pool txs. Instead it searches for
the txs the client explicitly requests.
- Reset `m_pool_info_query_time` when a user:
(1) rescans the chain (so the wallet re-requests the whole pool)
(2) changes the daemon their wallets points to (a new daemon would
have a different view of the pool)
- `/getblocks.bin` respects the `req.prune` field when returning
pool txs.
- Pool extension fields in response to `/getblocks.bin` are optional
with default 0'd values.
- Straight-forward call interface: `void rx_slow_hash(const char *seedhash, const void *data, size_t length, char *result_hash)`
- Consensus chain seed hash is now updated by calling `rx_set_main_seedhash` whenever a block is added/removed or a reorg happens
- `rx_slow_hash` will compute correct hash no matter if `rx_set_main_seedhash` was called or not (the only difference is performance)
- New environment variable `MONERO_RANDOMX_FULL_MEM` to force use the full dataset for PoW verification (faster block verification)
- When dataset is used for PoW verification, dataset updates don't stall other threads (verification is done in light mode then)
- When mining is running, PoW checks now also use dataset for faster verification
quick patch which fixes the issue where if you use some macros from `http_server_handlers_map2.h` you have to be in the `epee` namespace or it doesn't compile. Now can remove `using namespace epee;` from header file `core_rpc_server.h`, which caused a couple of name qualifying mistakes
While copying my data dir to another drive, I missed copying the rpc_ssl.key file b/c of the file permissions.
This change will give a much more clear, descriptive error in that scenario.
- grab an lmdb db_rtxn_guard to ensure consistent data from the db
- fixed on_getblockhash error resp when requested height >= blockchain height
- left functions that read shared memory untouched for now
This PR removes the requirement for --rpc-login to be specified if --rpc-access-control-origins is.
This will allow public nodes to serve cross-origin requests. You can still use --rpc-login with
--rpc-access-control-origins, but it is no longer mandatory.
