2ed4047840 chore: Make conan lockfile generation commands into a script (#6085)
This change moves the lockfile instructions into a script, and instead of removing packages it sets the Conan home directory to a temporary directory.

There are several advantages, such as:
* Not affecting the user's Conan home directory, so there is no need to remove packages.
* Only the script needs to be run, rather than several commands.

a18b30b765 docs: Update instructions how to (re)generate conan.lock file (#6070)
This change updates the instructions for how to generate a Conan lockfile that is compatible with Linux, macOS, and Windows.

Whenever Conan dependencies change, the Conan lock file needs to be regenerated. However, different OSes have slightly different requirements, and thus require slightly different dependencies. Luckily a single `conan.lock` file can be used, as long as the union of dependencies is included.

The current instructions in the `BUILD.md` file are insufficient to regenerate the lock file such that it is compatible with all OSes, which this change addresses. The three profiles contain the bare minimum needed to generate the lockfile; it does not particularly matter whether the build type is Debug or Release, for instance.

8449c6c365 Fix: nullptr resolving without db config (#6029)
If the config disables SQL db usage, such as a validator:

```
[ledger_tx_tables]
use_tx_tables = 0
```

then the pointer to DB engine is null, but it was still resolved during startup. Although it didn't crash in Release mode, possibly due to the compiler optimizing it away, it did crash in Debug mode. This change explicitly checks for the validity of the pointer and generates a runtime error if not set.

- Overflow Number -> int64 if it doesn't fit in the mantissa range.
- Only enabled if at least one of the SingleAssetVault or
  LendingProtocol amendments are enabled.
- Will throw the overflow error if the value is larger than maxMantissa.
  Current behavior is to throw if the value is larger than max int64_t
  value.

- Changed the EnforceInteger enum into a bool.
- Removed enforcement by throw.
- Essentially got rid of the "weak" and "strong" options.
- Removed integer options from STAmount. Since there's no throwing,
  there's no need to override the default.

2ebc2ca885 fix: floating point representation errors in vault (#5997)
This change fixes floating point errors in conversion of shares to assets and other way, used in `VaultDeposit`, `VaultWithdraw` and `VaultClawback`. In the floating point calculations the division introduces a larger error than multiplication. If we do division first, then the error introduced will be increased by the multiplication that follows, which is therefore the wrong order to perform these two operations. This change flips the order of arithmetic operations, which minimizes the error.

edb9b16583 fix: Use ".value()" instead of "->" when with STObject::Proxy objects
- Turns out that "Proxy::operator->" is not a safe substitute for
  "Proxy::value()." if the field is not required. The implementation
  is different such that "operator->" will return a null ptr if the
  field is not present. This includes default fields with a value of
  zero!

8e56af20ee Add a distinction between a "valid" and a "representable" Number
- "valid" means the value is <= Number::maxIntValue, which has been
  changed to maxMantissa / 100. A valid number could get bigger and be
  ok - such as when paying late interest on a loan.
- "representable" means the value is <= Number::maxMantissa. An
  unrepresentable number WILL be rounded or truncated.
- Adds a fourth level of enforcement: "compatible". It is used for
  converting XRP to Number (for AMM), and when doing explicit checks.
- "weak" will now throw if the number is unrepresentable.

The location of `rippled` binary in your build directory depends on your
CMake generator. Pass `--help` to see the rest of the command line options.
#### Conan lockfile
To achieve reproducible dependencies, we use [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html).
The `conan.lock` file in the repository contains a "snapshot" of the current dependencies.
It is implicitly used when running `conan` commands, you don't need to specify it.
You have to update this file every time you add a new dependency or change a revision or version of an existing dependency.
> [!NOTE]
> Conan uses local cache by default when creating a lockfile.
>
> To ensure, that lockfile creation works the same way on all developer machines, you should clear the local cache before creating a new lockfile.
To create a new lockfile, run the following commands in the repository root:
```bash
conan remove '*' --confirm
rm conan.lock
# This ensure that xrplf remote is the first to be consulted
conan remote add --force --index 0 xrplf https://conan.ripplex.io
conan lock create . -o '&:jemalloc=True' -o '&:rocksdb=True'
```
> [!NOTE]
> If some dependencies are exclusive for some OS, you may need to run the last command for them adding `--profile:all <PROFILE>`.

# Conan lockfile
To achieve reproducible dependencies, we use a [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html).
The `conan.lock` file in the repository contains a "snapshot" of the current
dependencies. It is implicitly used when running `conan` commands, so you don't
need to specify it.
You have to update this file every time you add a new dependency or change a
revision or version of an existing dependency.
To update a lockfile, run from the repository root: `./conan/lockfile/regenerate.sh`

[ed25519](http://ed25519.cr.yp.to/) is an
[Elliptic Curve Digital Signature Algortithm](http://en.wikipedia.org/wiki/Elliptic_Curve_DSA),
developed by [Dan Bernstein](http://cr.yp.to/djb.html),
[Niels Duif](http://www.nielsduif.nl/),
[Tanja Lange](http://hyperelliptic.org/tanja),
[Peter Schwabe](http://www.cryptojedi.org/users/peter/),
and [Bo-Yin Yang](http://www.iis.sinica.edu.tw/pages/byyang/).
This project provides performant, portable 32-bit & 64-bit implementations. All implementations are
of course constant time in regard to secret data.
#### Performance
SSE2 code and benches have not been updated yet. I will do those next.
Compilers versions are gcc 4.6.3, icc 13.1.1, clang 3.4-1~exp1.
Batch verification time (in parentheses) is the average time per 1 verification in a batch of 64 signatures. Counts are in thousands of cycles.
Note that SSE2 performance may be less impressive on AMD & older CPUs with slower SSE ops!
Visual Studio performance for `ge25519_scalarmult_base_niels` will lag behind a bit until optimized assembler versions of `ge25519_scalarmult_base_choose_niels`
are made.

#### Compilation
No configuration is needed **if you are compiling against OpenSSL**.
##### Hash Options
If you are not compiling aginst OpenSSL, you will need a hash function.
To use a simple/**slow** implementation of SHA-512, use `-DED25519_REFHASH` when compiling `ed25519.c`.
This should never be used except to verify the code works when OpenSSL is not available.
To use a custom hash function, use `-DED25519_CUSTOMHASH` when compiling `ed25519.c` and put your
custom hash implementation in ed25519-hash-custom.h. The hash must have a 512bit digest and implement
struct ed25519_hash_context;
void ed25519_hash_init(ed25519_hash_context *ctx);
void ed25519_hash_update(ed25519_hash_context *ctx, const uint8_t *in, size_t inlen);
void ed25519_hash_final(ed25519_hash_context *ctx, uint8_t *hash);
void ed25519_hash(uint8_t *hash, const uint8_t *in, size_t inlen);
##### Random Options
If you are not compiling aginst OpenSSL, you will need a random function for batch verification.
To use a custom random function, use `-DED25519_CUSTOMRANDOM` when compiling `ed25519.c` and put your
custom hash implementation in ed25519-randombytes-custom.h. The random function must implement:
void ED25519_FN(ed25519_randombytes_unsafe) (void *p, size_t len);
Use `-DED25519_TEST` when compiling `ed25519.c` to use a deterministically seeded, non-thread safe CSPRNG
variant of Bob Jenkins [ISAAC](http://en.wikipedia.org/wiki/ISAAC_%28cipher%29)
##### Minor options
Use `-DED25519_INLINE_ASM` to disable the use of custom assembler routines and instead rely on portable C.
Use `-DED25519_FORCE_32BIT` to force the use of 32 bit routines even when compiling for 64 bit.
##### 32-bit
gcc ed25519.c -m32 -O3 -c
##### 64-bit
gcc ed25519.c -m64 -O3 -c
##### SSE2
gcc ed25519.c -m32 -O3 -c -DED25519_SSE2 -msse2
gcc ed25519.c -m64 -O3 -c -DED25519_SSE2
clang and icc are also supported
#### Usage
To use the code, link against `ed25519.o -mbits` and:
#include "ed25519.h"
Add `-lssl -lcrypto` when using OpenSSL (Some systems don't need -lcrypto? It might be trial and error).
To generate a private key, simply generate 32 bytes from a secure
cryptographic source:
ed25519_secret_key sk;
randombytes(sk, sizeof(ed25519_secret_key));
To generate a public key:
ed25519_public_key pk;
ed25519_publickey(sk, pk);
To sign a message:
ed25519_signature sig;
ed25519_sign(message, message_len, sk, pk, signature);
To verify a signature:
int valid = ed25519_sign_open(message, message_len, pk, signature) == 0;
To batch verify signatures:
const unsigned char *mp[num] = {message1, message2..}
size_t ml[num] = {message_len1, message_len2..}
const unsigned char *pkp[num] = {pk1, pk2..}
const unsigned char *sigp[num] = {signature1, signature2..}
int valid[num]
/* valid[i] will be set to 1 if the individual signature was valid, 0 otherwise */
int all_valid = ed25519_sign_open_batch(mp, ml, pkp, sigp, num, valid) == 0;
**Note**: Batch verification uses `ed25519_randombytes_unsafe`, implemented in
`ed25519-randombytes.h`, to generate random scalars for the verification code.
The default implementation now uses OpenSSLs `RAND_bytes`.
Unlike the [SUPERCOP](http://bench.cr.yp.to/supercop.html) version, signatures are
not appended to messages, and there is no need for padding in front of messages.
Additionally, the secret key does not contain a copy of the public key, so it is
32 bytes instead of 64 bytes, and the public key must be provided to the signing
function.
##### Curve25519
Curve25519 public keys can be generated thanks to
[Adam Langley](http://www.imperialviolet.org/2013/05/10/fastercurve25519.html)
leveraging Ed25519's precomputed basepoint scalar multiplication.
curved25519_key sk, pk;
randombytes(sk, sizeof(curved25519_key));
curved25519_scalarmult_basepoint(pk, sk);
Note the name is curved25519, a combination of curve and ed25519, to prevent
name clashes. Performance is slightly faster than short message ed25519
signing due to both using the same code for the scalar multiply.
#### Testing
Fuzzing against reference implemenations is now available. See [fuzz/README](fuzz/README.md).
Building `ed25519.c` with `-DED25519_TEST` and linking with `test.c` will run basic sanity tests
and benchmark each function. `test-batch.c` has been incorporated in to `test.c`.
`test-internals.c` is standalone and built the same way as `ed25519.c`. It tests the math primitives
with extreme values to ensure they function correctly. SSE2 is now supported.

This code fuzzes ed25519-donna (and optionally ed25519-donna-sse2) against the ref10 implementations of
[curve25519](https://github.com/floodyberry/supercop/tree/master/crypto_scalarmult/curve25519/ref10) and
[ed25519](https://github.com/floodyberry/supercop/tree/master/crypto_sign/ed25519/ref10).
Curve25519 tests that generating a public key from a secret key
# Building
## *nix + PHP
`php build-nix.php (required parameters) (optional parameters)`
Required parameters:
* `--function=[curve25519,ed25519]`
* `--bits=[32,64]`
Optional parameters:
* `--with-sse2`
Also fuzz against ed25519-donna-sse2
* `--with-openssl`
Build with OpenSSL's SHA-512.
Default: Reference SHA-512 implementation (slow!)
* `--compiler=[gcc,clang,icc]`
Default: gcc
* `--no-asm`
Do not use platform specific assembler
example:
php build-nix.php --bits=64 --function=ed25519 --with-sse2 --compiler=icc
## Windows
Create a project with access to the ed25519 files.
If you are not using OpenSSL, add the `ED25519_REFHASH` define to the projects
"Properties/Preprocessor/Preprocessor Definitions" option
Add the following files to the project:
* `fuzz/curve25519-ref10.c`
* `fuzz/ed25519-ref10.c`
* `fuzz/ed25519-donna.c`
* `fuzz/ed25519-donna-sse2.c` (optional)
* `fuzz-[curve25519/ed25519].c` (depending on which you want to fuzz)
If you are also fuzzing against ed25519-donna-sse2, add the `ED25519_SSE2` define for `fuzz-[curve25519/ed25519].c` under
its "Properties/Preprocessor/Preprocessor Definitions" option.
# Running
If everything agrees, the program will only output occasional status dots (every 0x1000 passes)
and a 64bit progress count (every 0x20000 passes):
fuzzing: ref10 curved25519 curved25519-sse2
................................ [0000000000020000]
................................ [0000000000040000]

................................ [00000000000a0000]
................................ [00000000000c0000]
If any of the implementations do not agree with the ref10 implementation, the program will dump
the random data that was used, the data generated by the ref10 implementation, and diffs of the
ed25519-donna data against the ref10 data.
## Example errors
These are example error dumps (with intentionally introduced errors).

Introducing the 128 bit r scalars to the heap _before_ the largest scalar
fits in to 128 bits alters the heap shape and produces a different,
yet still neutral/valid y/z value.
This was the value of introducing the r scalars when the largest scalar fit
in to 135-256 bits. You can produce it with amd64-64-24k / amd64-51-32k
with the random sequence used in the first pass by changing
unsigned long long hlen=((npoints+1)/2)|1;
to
unsigned long long hlen=npoints;
in ge25519_multi_scalarmult.c
ed25519-donna-batchverify.h has been modified to match the
default amd64-64-24k / amd64-51-32k behaviour
