Otherwise figuring out what's wrong with your JSON can be tricky,
especially if you're using a single fmt string to validate a large,
complicated schema.
The comma delimiting will make separating keys that contain commas
difficult. For example:
{"foo, bar": true, "baz": false}
will generate errors like:
2 object item(s) left unpacked: foo, bar, baz
but that seems like a small enough corner case to not be worth much
worrying.
I wanted to find a way to handle this without have_unrecognized_keys,
but the strbuffer tooling makes it look like I shouldn't be reaching
in to do things like:
strbuffer_t unrecognized_keys;
unrecognized_keys.value = NULL;
and then using 'unrecognized_keys.value == NULL' in place of
have_unrecognized_keys.
This is both good practice and nice for OpenBSD users, who will no
longer get the nag message to not use sprintf/strcpy every time they
link against jansson. It's worth noting that the existing code seems
safe to me - bounds checks were already happening before the actual
calls - and that this is for extra security.
This has the consequence that numbers are never converted to integers
when JSON_DECODE_INT_AS_REAL is set, and thus it works correctly all
integers that are representable as double.
Fixes#212.
This adds support for http://coveralls.io/ to the cmake project. This can then be run via a new Travis job, which uploads json containing the coverage data to the website.
To use this, please login usin github at http://coveralls.io/ and enable the Jansson project. You can then get a nice percentage badge for code coverage after each Travis buid. Coveralls will also comment on pull request with coverage info.
To test and run it locally do:
```bash
$ mkdir build && cd build
$ cmake -DJANSSON_COVERALLS=ON -DCMAKE_BUILD_TYPE=Debug ..
$ cmake --build . # $ make
$ cmake --build . --target coveralls # $ make coveralls
```
There is also another script that generates a local HTML page using lcov CodeCoverage.cmake which can be run using
```bash
$ make coverage
```
The required depdencies to run this are:
gcov
curl
lcov (is needed for the normal CodeCoverage script)
