Merge branch 'develop' into claude/bjdata-ndarray-round-trip-5661

Browse Source 
- binary_reader: keep emitting "_ArrayType_" from get_ubjson_size_value()
  (before "_ArraySize_"), now via develop's static bjd_type_name(); drop
  develop's later emission in get_ubjson_array()
- binary_writer: develop's out-of-range check for ND-array elements
  (#5473, #5730) now also requires that single-precision elements survive
  the narrowing exactly, which is what this branch adds for #5661

//
// A decimal number with up to 18 digits is always representable in
// both std::uint64_t and std::int64_t (18 nines is ~1e18, well below
// both UINT64_MAX ~1.8e19 and INT64_MAX ~9.2e18), so strtoull()/strtoll()

// so their handling -- including reclassification to value_float when
// the value overflows 64 bits, and rejection when it is not even
// finite as a double -- is bit-for-bit identical to before this
// optimization.
// With a narrower number_unsigned_t/number_integer_t (e.g.
// std::uint32_t), the exact path would reclassify some of these tokens
// as (finite) floats, while this check reports integers. That does not
// change the result of accept(): it always parses through
// json_sax_acceptor, whose number callbacks discard their argument and
// return true, and the parser rejects neither integers nor finite
// floats. value_unsigned/value_integer are left unset here, so a caller
// that reads the converted value must not set discard_number_values.
//
// Note this reasons about std::uint64_t/std::int64_t, not about
// number_unsigned_t/number_integer_t (BasicJsonType's own, possibly
// narrower, template parameters -- e.g. std::uint32_t). That is fine
// *only* because discard_number_values is exclusively set by
// accept() (see json.hpp), and accept() always parses through the
// library's own json_sax_acceptor -- never a user-supplied SAX
// consumer -- whose number_unsigned()/number_integer()/number_float()
// callbacks unconditionally discard their argument and return true.
// So for every caller that can reach this branch, neither the token
// classification below nor the eventual (possibly narrowed, and on
// this fast path left stale/unset) value_unsigned/value_integer is
// ever consulted -- an unsigned/integer token is accepted outright,
// and even a >18-digit token that this fast path deliberately falls
// through for is, once reclassified to value_float, still finite
// (and thus accepted) for any digit count that fits in number_unsigned_t
// or number_integer_t regardless of that type's width. If this

handler, or another thread) must not truncate the value (#5198). The

decimal point changed in the meantime, the locale changed between the
lookup and the call, and the conversion is repeated with the new decimal
point. If the decimal point did not change, a retry cannot succeed: the
locale's decimal point is not a single character (e.g., the two-byte
U+066B of ar_EG.UTF-8 or fa_IR.UTF-8) and cannot be substituted in place.
The value strtod parsed up to that point is kept, as before this change.
Note that changing the locale in another thread *while* strtod runs is
undefined behavior of the C library, which this function cannot prevent.

@brief convert a validated float token with strtof/strtod/strtold
These functions expect the decimal point of the *current* locale, so it is
looked up right before the conversion instead of once when the lexer is
constructed: a locale change in between (by a parser callback, a SAX
handler, or another thread) must not truncate the value (#5198). The
token has been validated before, so if the conversion stops early and the
decimal point changed in the meantime, the locale changed between the
lookup and the call, and the conversion is repeated with the new decimal
point. If the decimal point did not change, a retry cannot succeed: the
locale's decimal point is not a single character (e.g., the two-byte
U+066B of ar_EG.UTF-8 or fa_IR.UTF-8) and cannot be substituted in place.
The value strtod parsed up to that point is kept, as before this change.
Note that changing the locale in another thread *while* strtod runs is
undefined behavior of the C library, which this function cannot prevent.
@param[in,out] token the token with '.' as decimal point; its
decimal point is replaced during the
conversion and restored afterwards
(data() must be NUL-terminated)
@param[in] decimal_point_position index of the '.' in @a token, or
