----------
|
|
|
|
* Updated the type system's behavior, in order to better support backwards
|
|
compatibility with code that was written before 64-bit integer support was
|
|
introduced. Here's how it works now:
|
|
|
|
* isInt, isInt64, isUInt, and isUInt64 return true if and only if the
|
|
value can be exactly represented as that type. In particular, a value
|
|
constructed with a double like 17.0 will now return true for all of
|
|
these methods.
|
|
|
|
* isDouble and isFloat now return true for all numeric values, since all
|
|
numeric values can be converted to a double or float without
|
|
truncation. Note however that the conversion may not be exact -- for
|
|
example, doubles cannot exactly represent all integers above 2^53 + 1.
|
|
|
|
* isBool, isNull, isString, isArray, and isObject now return true if and
|
|
only if the value is of that type.
|
|
|
|
* isConvertibleTo(fooValue) indicates that it is safe to call asFoo.
|
|
(For each type foo, isFoo always implies isConvertibleTo(fooValue).)
|
|
asFoo returns an approximate or exact representation as appropriate.
|
|
For example, a double value may be truncated when asInt is called.
|
|
|
|
* For backwards compatibility with old code, isConvertibleTo(intValue)
|
|
may return false even if type() == intValue. This is because the value
|
|
may have been constructed with a 64-bit integer larger than maxInt,
|
|
and calling asInt() would cause an exception. If you're writing new
|
|
code, use isInt64 to find out whether the value is exactly
|
|
representable using an Int64, or asDouble() combined with minInt64 and
|
|
maxInt64 to figure out whether it is approximately representable.
|
|
|
|
* Value
|
|
- Patch #10: BOOST_FOREACH compatibility. Made Json::iterator more
|
|
standard compliant, added missing iterator_category and value_type
|
|
typedefs (contribued by Robert A. Iannucci).
|
|
|
|
* Compilation
|
|
|
|
- New CMake based build system. Based in part on contribution from
|
|
Igor Okulist and Damien Buhl (Patch #14).
|
|
|
|
- New header json/version.h now contains version number macros
|
|
(JSONCPP_VERSION_MAJOR, JSONCPP_VERSION_MINOR, JSONCPP_VERSION_PATCH
|
|
and JSONCPP_VERSION_HEXA).
|
|
|
|
- Patch #11: added missing JSON_API on some classes causing link issues
|
|
when building as a dynamic library on Windows
|
|
(contributed by Francis Bolduc).
|
|
|
|
- Visual Studio DLL: suppressed warning "C4251: <data member>: <type>
|
|
needs to have dll-interface to be used by..." via pragma push/pop
|
|
in json-cpp headers.
|
|
|
|
- Added Travis CI intregration: https://travis-ci.org/blep/jsoncpp-mirror
|
|
|
|
* Bug fixes
|
|
- Patch #15: Copy constructor does not initialize allocated_ for stringValue
|
|
(contributed by rmongia).
|
|
|
|
- Patch #16: Missing field copy in Json::Value::iterator causing infinite
|
|
loop when using experimental internal map (#define JSON_VALUE_USE_INTERNAL_MAP)
|
|
(contributed by Ming-Lin Kao).
|
|
|
|
|
|
New in JsonCpp 0.6.0:
|
|
---------------------
|
|
|
|
* Compilation
|
|
|
|
- LD_LIBRARY_PATH and LIBRARY_PATH environment variables are now
|
|
propagated to the build environment as this is required for some
|
|
compiler installation.
|
|
|
|
- Added support for Microsoft Visual Studio 2008 (bug #2930462):
|
|
The platform "msvc90" has been added.
|
|
|
|
Notes: you need to setup the environment by running vcvars32.bat
|
|
(e.g. MSVC 2008 command prompt in start menu) before running scons.
|
|
|
|
- Added support for amalgamated source and header generation (a la sqlite).
|
|
Refer to README.txt section "Generating amalgamated source and header"
|
|
for detail.
|
|
|
|
* Value
|
|
|
|
- Removed experimental ValueAllocator, it caused static
|
|
initialization/destruction order issues (bug #2934500).
|
|
The DefaultValueAllocator has been inlined in code.
|
|
|
|
- Added support for 64 bits integer:
|
|
|
|
Types Json::Int64 and Json::UInt64 have been added. They are aliased
|
|
to 64 bits integers on system that support them (based on __int64 on
|
|
Microsoft Visual Studio platform, and long long on other platforms).
|
|
|
|
Types Json::LargestInt and Json::LargestUInt have been added. They are
|
|
aliased to the largest integer type supported:
|
|
either Json::Int/Json::UInt or Json::Int64/Json::UInt64 respectively.
|
|
|
|
Json::Value::asInt() and Json::Value::asUInt() still returns plain
|
|
"int" based types, but asserts if an attempt is made to retrieve
|
|
a 64 bits value that can not represented as the return type.
|
|
|
|
Json::Value::asInt64() and Json::Value::asUInt64() have been added
|
|
to obtain the 64 bits integer value.
|
|
|
|
Json::Value::asLargestInt() and Json::Value::asLargestUInt() returns
|
|
the integer as a LargestInt/LargestUInt respectively. Those functions
|
|
functions are typically used when implementing writer.
|
|
|
|
The reader attempts to read number as 64 bits integer, and fall back
|
|
to reading a double if the number is not in the range of 64 bits
|
|
integer.
|
|
|
|
Warning: Json::Value::asInt() and Json::Value::asUInt() now returns
|
|
long long. This changes break code that was passing the return value
|
|
to *printf() function.
|
|
|
|
Support for 64 bits integer can be disabled by defining the macro
|
|
JSON_NO_INT64 (uncomment it in json/config.h for example), though
|
|
it should have no impact on existing usage.
|
|
|
|
- The type Json::ArrayIndex is used for indexes of a JSON value array. It
|
|
is an unsigned int (typically 32 bits).
|
|
|
|
- Array index can be passed as int to operator[], allowing use of literal:
|
|
Json::Value array;
|
|
array.append( 1234 );
|
|
int value = array[0].asInt(); // did not compile previously
|
|
|
|
- Added float Json::Value::asFloat() to obtain a floating point value as a
|
|
float (avoid lost of precision warning caused by used of asDouble()
|
|
to initialize a float).
|
|
|
|
* Reader
|
|
|
|
- Renamed Reader::getFormatedErrorMessages() to getFormattedErrorMessages.
|
|
Bug #3023708 (Formatted has 2 't'). The old member function is deprecated
|
|
but still present for backward compatibility.
|
|
|
|
* Tests
|
|
|
|
- Added test to ensure that the escape sequence "\/" is corrected handled
|
|
by the parser.
|
|
|
|
* Bug fixes
|
|
|
|
- Bug #3139677: JSON [1 2 3] was incorrectly parsed as [1, 3]. Error is now
|
|
correctly detected.
|
|
|
|
- Bug #3139678: stack buffer overflow when parsing a double with a
|
|
length of 32 characters.
|
|
|
|
- Fixed Value::operator <= implementation (had the semantic of operator >=).
|
|
Found when adding unit tests for comparison operators.
|
|
|
|
- Value::compare() is now const and has an actual implementation with
|
|
unit tests.
|
|
|
|
- Bug #2407932: strpbrk() can fail for NULL pointer.
|
|
|
|
- Bug #3306345: Fixed minor typo in Path::resolve().
|
|
|
|
- Bug #3314841/#3306896: errors in amalgamate.py
|
|
|
|
- Fixed some Coverity warnings and line-endings.
