This commit removed the re2c lexer and replaced it by a manual version.
Its integration is not yet complete: number parsing does not respect
locales or overflows. Furthermore, parsing does not need to end with
EOF. Therefore, a lot of test cases fail. The idea is to push this
branch forward so we can conduct performance comparisons. So far, a
nice side effect are better diagnosis messages in case of parse errors.
We should compare the binary serializations rather than the JSON values
themselves. This fix was already done for CBOR and apparently forgotten
for MessagePack.
- Removed unused headers.
- Added override where needed.
- Added description for parse_error.113 exception.
- Fixed some conversion warnings.
- Integrated cbor_expect_string function for CBOR maps.
- Added documentation on the supported CBOR/MessagePack features.
- Added test to check all initial bytes for CBOR input.
When <Windows.h> is included with MSVC, a macro NOMINMAX is defined
that yields compilation errors when max/min calls are encountered. This
can be fixed by un-defining NOMINMAX, or by placing parentheses around
all min/max calls. We chose the latter.
Since #329, NaN and inf numbers do not yield an exception, but are
stored internally and are dumped as “null”. This commit adjusts the
fuzz testers to deal with this special case.
- If an overflow occurs during parsing a number from a JSON text, an
exception (std::out_of_range for the moment, to be replaced by a
user-defined exception #244) is thrown so that the overflow is detected
early and roundtripping is guaranteed.
- NaN and INF floating-point values can be stored in a JSON value and
are not replaced by null. That is, the basic_json class behaves like
double in this regard (no exception occurs). However, NaN and INF are
serialized to “null”.
- Adjusted test cases appropriately.
To avoid the error described in #497, I added a function
msgpack_expect_string that is executed every time a string is expected
during the parsing of a map. In case the current byte does not belong
to a MsgPack string, an exception is thrown.
This test case relied on logics that have been replaced by CMake with
#461. This change enables compilation and execution of the test suite
without exceptions by adding an after_success task.
Added a test to check if the input stream is good() before executing
getline on it. Also added two test cases that set the failbit and
badbit before calling file_line_buffer.
I used __EXCEPTIONS to detect whether exceptions are supported.
Apparently, this is a macro that is only used by libstdc++
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64276). It’s much cleaner
to use __cpp_exceptions as it is in the standard since C++98.
Note that compiling the unit-tests with “-fno-exceptions” still does
not work, because Catch uses throw internally. However, the library’s
exceptions can be switched off by defining JSON_NOEXCEPTION.
