1.3.1

Bugfix release that fixes an out of bounds read #118. This shouldn't have any security implications.

1.3.0

This release includes a lot of rework in the parser and includes the Cunity unit testing framework, as well as some fixes. I increased the minor version number because there were quite a lot of internal changes.

Features:

• New type for cJSON structs: cJSON_Invalid (#108)

Fixes:

• runtime checks for a lot of potential integer overflows
• fix incorrect return in cJSON_PrintBuffered (cf9d57d56c)
• fix several potential issues found by Coverity
• fix potentially undefined behavior when assigning big numbers to valueint (41e2837df1)
  • Numbers exceeding INT_MAX or lower than INT_MIN will be explicitly assigned to valueint as INT_MAX and INT_MIN respectively (saturation on overflow).
  • fix the cJSON_SetNumberValue macro (87f77274de), this slightly changes the behavior, see commit message

Introduce unit tests

Started writing unit tests with the Cunity testing framework. Currently this covers the parser functions.

Also:

• Support for running the tests with Valgrind
• Support for compiling the tests with AddressSanitizer and UndefinedBehaviorSanitizer.
• travis.yml file for running unit tests on travis. (not enabled for the repository yet though #102)

Simplifications

After having unit tests for the parser function in place, I started refactoring the parser functions (as well as others) and making them easier to read and maintain.

• Use strtod from the standard library for parsing numbers (0747669972)
• Use goto-fail in several parser functions (#100)
• Rewrite/restructure all of the parsing functions to be easier to understand and have less code paths doing the same as another. (#109)
• Simplify the buffer allocation strategy to always doubling the needed amount (9f6fa94c91)
• Combined cJSON_AddItemToObject and cJSON_AddItemToObjectCS to one function (cf862d0fed)

Other changes

• Prevent the usage of incompatible C and header versions via preprocessor directive (123bb1af7b)
• Let CMake automatically detect compiler flags
• Add new compiler flags (-Wundef, -Wswitch-default, -Wconversion, -fstack-protector-strong) (#98)
• Change internal sizes from int to size_t (ecd5678527)
• Change internal strings from char* to unsigned char* (28b9ba4334)
• Add const in more places
