- Refactor Number internals away from int64 to uint64 & a sign flag
  - ctors and accessors return `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.

refactor: Update Conan dependencies: protobuf and grpc (#5589)

This PR updates protobuf and grpc to their latest versions. The latest protobuf version no longer requires patches, so we can use it directly from the official Conan Center Index, while the latest grpc still needed a patch, which was added to our own Conan Center Index fork in XRPLF/conan-center-index#8.

cleanup

docs: Infer version of Conan dependency to export (#6112)

This change updates a script in the documentation to automatically infer the version of a patched Conan dependency from the conan.lock file.

chore: Use updated secp256k1 recipe (#6118)

This change updates the secp256k1 recipe that defines the SECP256K1_STATIC, so it no longer needs to be defined in the code here. Running the Conan update script also updated two other recipes in the lock file.

chore: Clean up .gitignore and .gitattributes (#6001)

The .gitignore and .gitattributes files contain references to files and directories that the current build no longer produces, so this change removes obsolete entries in these files, and does some general reorganizing of the remaining entries.

chore: Fix docs readme and cmake (#6122)

This change removes the unused `with_docs` option and fixes the README instructions on how to build the `docs` target.

minor clean-up

Signed-off-by: Pratik Mankawde <3397372+pratikmankawde@users.noreply.github.com>

refactor: clean up `RPCHelpers` (#5684)

This PR cleans up `RPCHelpers.h` and `RPCHelpers.cpp`. It splits out all the fetch-ledger functions to a new set of files, `RPCLedgerHelpers.h`/`RPCLedgerHelpers.cpp`, and moves the general-API functions to `ApiVersion.h`. There is no functionality change.

refactor: rename `LedgerInfo` to `LedgerHeader` (#6136)

This PR renames `LedgerInfo` to `LedgerHeader`. Namely, `LedgerInfo` was already an alias for `LedgerHeader`, and the comments next to the alias suggested that it would make sense to rename it, since that makes it clearer what it is.

refactor: rename info() to header() (#6138)

This change renames all the `info()` functions to `header()`, since they return `LedgerHeader` structs. It also renames the underlying variables from `info_` to `header_`.

refactor: Rename `rippled` binary to `xrpld` (#5983)

Per [XLS-0095](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html), we are taking steps to rename ripple(d) to xrpl(d).

This change modifies the binary name from `rippled` to `xrpld`, and creates a symlink named `rippled` that points to the `xrpld` binary.

Note that #5975 renamed any references to `rippled` in the CMake files and their contents, but explicitly maintained the `rippled` binary name by adding an exception. This change now undoes this exception and adds an explicit symlink instead.

refactor: Move JobQueue and related classes into xrpl.core module (#6121)

refactor: Rename `ripple` namespace to `xrpl` (#5982)

This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.

chore: Fix some typos in comments (#6082)

ci: Update shared actions (#6147)

The latest update to `cleanup-workspace`, `get-nproc`, and `prepare-runner` moved the action to the repository root directory, and also includes some ccache changes. In response, this change updates the various shared actions to the latest commit hash.

refactor: remove `Json::Object` and related files/classes (#5894)

`Json::Object` and related objects are not used at all, so this change removes `include/xrpl/json/Object.h` and all downstream files. There are a number of minor downstream changes as well.

Full list of deleted classes and functions:
* `Json::Collections`
* `Json::Object`
* `Json::Array`
* `Json::WriterObject`
* `Json::setArray`
* `Json::addObject`
* `Json::appendArray`
* `Json::appendObject`

The last helper function, `copyFrom`, seemed a bit more complex and was actually used in a few places, so it was moved to `LedgerToJson.h` instead of deleting it.

Set version to 3.2.0-b0 (#6153)

ci: Remove superfluous build directory creation (#6159)

This change modifies the build directory structure from `build/build/xxx` or `.build/build/xxx` to just `build/xxx`. Namely, the `conanfile.py` has the CMake generators build directory hardcoded to `build/generators`. We may as well leverage the top-level build directory without introducing another layer of directory nesting.

fix: Remove cryptographic libs from libxrpl Conan package (#6163)

Revert "chore: Pin ruamel.yaml<0.19 in pre-commit-hooks (#6166)" (#6167)

This reverts commit 0f23ad8.

refactor: Rename `rippled.cfg` to `xrpld.cfg` (#6098)

This change renames all occurrences of `rippled.cfg` to `xrpld.cfg`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts. For the time being it maintains support for `rippled.cfg` as config file, if `xrpld.cfg` does not exist.

test: add more tests for `ledger_entry` RPC (#5858)

This change adds some basic tests for all the `ledger_entry` helper functions, so each ledger entry type is covered. There are further some minor refactors in `parseAMM` to provide better error messages. Finally, to improve readability, alphabetization was applied in the helper functions.

ci: Use ccache to cache build objects for speeding up building (#6104)

Right now, each pipeline invocation builds the source code from scratch. Although compiled Conan dependencies are cached in a remote server, the source build objects are not. We are able to further speed up our builds by leveraging `ccache`. This change enables caching of build objects using `ccache` on Linux, macOS, and Windows.

ci: Move variable into right place (#6179)

This change moves the `enable_ccache` variable in the `on-trigger.yml` file to the correct location.

refactor: Fix typos in comments, configure cspell (#6164)

This change sets up a `cspell `configuration and fixes lots of typos in comments. There are no other code changes.

refactor: Fix spelling issues in private/local variables and functions (#6182)

This change fixes several typos in private/local variables and private functions. There is no functionality change.

refactor: Fix spelling issues in all variables/functions (#6184)

This change fixes many typos in comments, variables, and public functions. There is no functionality change.

refactor: Remove unused credentials signature hash prefix (#6186)

This change removes the unused credentials signature hash prefix from `HashPrefix.h`.

fix: Reorder Batch Preflight Errors (#6176)

This change fixes #6058.

refactor: Fix typos, enable cspell pre-commit (#5719)

This change fixes the last of the spelling issues, and enables the pre-commit (and CI) check for spelling. There are no functionality changes, but it does rename some enum values.

ci: Use updated prepare-runner in actions and worfklows (#6188)

This change updates the XRPLF pre-commit workflow and prepare-runner action to their latest versions. For naming consistency the prepare-runner action changed the disable_ccache variable into enable_ccache, which matches our naming.

docs: Fix minor spelling issues in comments (#6194)

fix: Truncate thread name to 15 chars on Linux (#5758)

This change:
* Truncates thread names if more than 15 chars with `snprintf`.
* Adds warnings for truncated thread names if `-DTRUNCATED_THREAD_NAME_LOGS=ON`.
* Add a static assert for string literals to stop compiling if > 15 chars.
* Shortens `Resource::Manager` to `Resource::Mngr` to fix the static assert failure.
* Updates `CurrentThreadName_test` unit test specifically for Linux to verify truncation.

VaultClawback: Burn shares of an empty vault (#6120)

- Adds a mechanism for the vault owner to burn user shares when the vault is stuck. If the Vault has 0 AssetsAvailable and Total, the owner may submit a VaultClawback to reclaim the worthless fees, and thus allow the Vault to be deleted. The Amount must be left off (unless the owner is the asset issuer), specified as 0 Shares, or specified as the number of Shares held.

chore: Change `/Zi` to `/Z7` for ccache, remove debug symbols in CI (#6198)

As the `/Zi` compiler flag is unsupported by ccache, this change switches it to `/Z7` instead. For CI runs all debug info is omitted.

fix: Inner batch transactions never have valid signatures (#6069)

- Introduces amendment `fixBatchInnerSigs`
- Update Batch unit tests
  - Fix all the Env instantiations to _use_ the "features" parameter.
  - testInnerSubmitRPC runs with Batch enabled and disabled.
  - Add a test to testInnerSubmitRPC for a correctly signed tx incorrectly
    using the tfInnerBatchTxn flag.
  - Generalize the submitAndValidate lambda in testInnerSubmitRPC.
  - With the fix amendment, a transaction never reaches the transaction
    engine (Transactor and derived classes.)
  - Test submitting a pseudo-transaction. Stopped before reaching the
    transaction engine, but with different errors.
- The tests verify that without the amendment, a transaction with
  tfInnerBatchTxn is immediately rejected. Without the amendment, things
  are safe. The amendment just makes things safer and more future-proof.

chore: Pin pre-commit hooks to commit hashes (#6205)

This change updates and pins the Black and CSpell pre-commit hooks.

refactor: Remove unnecessary version number and options in cmake find_package (#6169)

This change removes unnecessary version numbers in the OpenSSL and Boost `find_package` CMake statements. An unnecessary OpenSSL definition is removed, while Conan options for SSL are updated to disable insecure ciphers. Moreover, the statements are now ordered alphabetically and more logically.

ci: Update actions/images to use cmake 4.2.1 and conan 2.24.0 (#6209)

    Fix overpayment asserts (#6084)

    MPTTester::operator() parameter should be std::int64_t
    - Originally defined as uint64_t, but the testIssuerLoan() test called
      it with a negative number, causing an overflow to a very large number
      that in some circumstances could be silently cast back to an int64_t,
      but might not be. I believe this is UB, and we don't want to rely on
      that.

    Review feedback from @Tapanito: overpayment value change
    - In overpayment results, the management fee was being calculated twice:
      once as part of the value change, and as part of the fees paid.
      Exclude it from the value change.

    Fix Overpayment Calculation  (#6087)
    - Adds additional unit tests to cover math calculations.
    - Removes unused methods.

    Review feedback from @shawnxie999: even more rounding
    - Round the initial total value computation upward, unless there is
      0-interest.
    - Rename getVaultScale to getAssetsTotalScale, and convert one incorrect
      computation to use it.
    - Use adjustImpreciseNumber for LossUnrealized.
    - Add some logging to computeLoanProperties.

    Fix LoanBrokerSet debtMaximum limits (#6116)

    * Replace accountHolds with accountSpendable when checking
    for account funds in VaultDeposit and LoanBrokerCoverDeposit

    Add a few minor changes (#6158)
    - Updates or fixes a couple of things I noticed while reviewing changes
      to the spec.
    - Rename sfPreviousPaymentDate to sfPreviousPaymentDueDate.
    - Make the vault asset cap check added in #6124 a little more robust:
      1. Check in preflight if the vault is _already_ over the limit.
      2. Prevent overflow when checking with the loan value. (Subtract
         instead of adding, in case the values are near maxint. Both return
         the same result. Also add a unit test so each case is covered.

    Add minimum grace period validation (#6133)

    Fix bugs: frozen pseudo-account, and FLC cutoff (#6170)

Expand Number to support the full integer range (#6025)

Improve ledger_entry lookups for fee, amendments, NUNL, and hashes (#5644)

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.

ci: remove 'master' branch as a trigger (#6234)

This change removes the `master` branch as a trigger for the CI pipelines, and updates comments accordingly. It also fixes the pre-commit workflow, so it will run on all release branches.
