This change enforces a maximum length of 63 characters on feature names, as well as not permitting an exactly 32 character long feature name to avoid confusion with those that use a `uint256` hex representation, as that is an alternative way to specify a feature. This change further prevents the use of Unicode characters in feature names, because some can be confused with regular ASCII characters despite being valid in identifiers.
Subscribe tests have a problem that there is no way to synchronize application running in background threads and test threads. Threads are communicating via websocket messages. When the code is compiled in debug mode with code coverage enabled it executes quite slow, so receiving websocket messages by the client in subscribe tests may time out.
This change does 2 things to fix the problem:
* Increases timeout for receiving a websocket message.
* Decreases the number of tests running in parallel.
While testing the fix for subscribe test another flaky test in ledger replay was found, which has also been addressed.
This change reorganizes the `tx/transactors` directory for consistency and discoverability. There are no behavioral changes, this is a pure refactor. Underscores were chosen as the way to separate multi-words as this is the more popular option in C++ projects.
Specific changes:
- Rename all subdirectories to lowercase/snake_case (`AMM` → `amm`, `Check` → `check`, `NFT` → `nft`, `PermissionedDomain` → `permissioned_domain`, etc.)
- Merge `AMM/` and `Offer/` into `dex/`, including `PermissionedDEXHelpers`
- Rename `MPT/` → `token/`, absorbing `SetTrust` and `Clawback`
- Move top-level transactors into named groups: `account/`, `bridge/`, `credentials/`, `did/`, `escrow/`, `oracle/`, `payment/`, `payment_channel/`, `system/`
- Update all include paths across the codebase and `transactions.macro`
When `gateway_balances` gets called on an account that is involved in the `EscrowCreate` transaction (with MPT being escrowed), the method returns internal error. This change fixes this case by excluding the MPT type when totaling escrow amount.
The `Subscribe` tests were flaky, because each test performs some operations (e.g. sends transactions) and waits for messages to appear in subscription with a 100ms timeout. If tests are slow (e.g. compiled in debug mode or a slow machine) then some of them could fail. This change adds an attempt to synchronize the background Env's thread and the test's thread by ensuring that all the scheduled operations are started before the test's thread starts to wait for a websocket message. This is done by limiting I/O threads of the app inside Env to 1 and adding a synchronization barrier after closing the ledger.
The rdb module was not properly designed, which is fixed in this change. The module had three classes:
1) The abstract class `RelationalDB`.
2) The abstract class `SQLiteDatabase`, which inherited from `RelationalDB` and added some pure virtual methods.
3) The concrete class `SQLiteDatabaseImp`, which inherited from `SQLiteDatabase` and implemented all methods.
The updated code simplifies this as follows:
* The `SQLiteDatabaseImp` has become `SQLiteDatabase`, and
* The former `SQLiteDatabase `has merged with `RelationalDatabase`.
This change modularizes the `WalletDB` and `Manifest`. Note that the wallet db has nothing to do with account wallets and it stores node configuration, which is why it depends on the manifest code.
Since the minimum Clang version we support is 16, the checks for version < 15 are no longer necessary. This change therefore removes the macros checking if the clang version is < 15 and simplifies uses of `std::source_location`.
These "fixed location" objects can be found in multiple ways:
1. The lookup parameters use the same format as other ledger objects, but the only valid value is true or the valid index of the object:
- Amendments: "amendments" : true
- FeeSettings: "fee" : true
- NegativeUNL: "nunl" : true
- LedgerHashes: "hashes" : true (For the "short" list. See below.)
2. With RPC API >= 3, using special case values to "index", such as "index" : "amendments". Uses the same names as above. Note that for "hashes", this option will only return the recent ledger hashes / "short" skip list.
3. LedgerHashes has two types: "short", which stores recent ledger hashes, and "long", which stores the flag ledger hashes for a particular ledger range.
- To find a "long" LedgerHashes object, request '"hashes" : <ledger sequence>'. <ledger sequence> must be a number that evaluates to an unsigned integer.
- To find the "short" LedgerHashes object, request "hashes": true as with the other fixed objects.
The following queries are all functionally equivalent:
- "amendments" : true
- "index" : "amendments" (API >=3 only)
- "amendments" : "7DB0788C020F02780A673DC74757F23823FA3014C1866E72CC4CD8B226CD6EF4"
- "index" : "7DB0788C020F02780A673DC74757F23823FA3014C1866E72CC4CD8B226CD6EF4"
Finally, whether the object is found or not, if a valid index is computed, that index will be returned. This can be used to confirm the query was valid, or to save the index for future use.
- Refactor Number internals away from int64 to uint64 & a sign flag
- ctors and accessors use `rep`. Very few things expose
`internalrep`.
- An exception is "unchecked" and the new "normalized", which explicitly
take an internalrep. But with those special control flags, it's easier
to distinguish and control when they are used.
- For now, skip the larger mantissas in AMM transactions and tests
- Remove trailing zeros from scientific notation Number strings
- Update tests. This has the happy side effect of making some of the string
representations _more_ consistent between the small and large
mantissa ranges.
- Add semi-automatic rounding of STNumbers based on Asset types
- Create a new SField metadata enum, sMD_NeedsAsset, which indicates
the field should be associated with an Asset so it can be rounded.
- Add a new STTakesAsset intermediate class to handle the Asset
association to a derived ST class. Currently only used in STNumber,
but could be used by other types in the future.
- Add "associateAsset" which takes an SLE and an Asset, finds the
sMD_NeedsAsset fields, and associates the Asset to them. In the case
of STNumber, that both stores the Asset, and rounds the value
immediately.
- Transactors only need to add a call to associateAsset _after_ all of
the STNumbers have been set. Unfortunately, the inner workings of
STObject do not do the association correctly with uninitialized
fields.
- When serializing an STNumber that has an Asset, round it before
serializing.
- Add an override of roundToAsset, which rounds a Number value in place
to an Asset, but without any additional scale.
- Update and fix a bunch of Loan-related tests to accommodate the
expanded Number class.
