Build changes ------------- * #639/#621 - Add symbol versions to all exported symbols * #508/#634 - Always enable -fPIC to allow use of the json-c static library in other libraries * Build both static and shared libraries at the same time. * #626 - Restore compatibility with cmake 2.8 * #471 - Always create directories with mode 0755, regardless of umask. * #606/#604 - Improve support for OSes like AIX and IBM i, as well as for MINGW32 and old versions of MSVC * #451/#617 - Add a DISABLE_THREAD_LOCAL_STORAGE cmake option to disable the use of thread-local storage. Significant changes and bug fixes --------------------------------- * Split the internal json_object structure into several sub-types, one for each json_type (json_object_object, json_object_string, etc...). This improves memory usage and speed, with the benchmark under bench/ report 5.8% faster test time and 6%(max RSS)-12%(peak heap) less memory usage. Memory used just for json_object structures decreased 27%, so use cases with fewer arrays and/or strings would benefit more. * Minimize memory usage in array handling in json_tokener by shrinking arrays to the exact number of elements parsed. On bench/ benchmark: 9% faster test time, 39%(max RSS)-50%(peak heap) less memory usage. Add json_object_array_shrink() and array_list_shrink() functions. * #616 - Parsing of surrogate pairs in unicode escapes now properly handles incremental parsing. * Fix incremental parsing of numbers, especially those with exponents, e.g. so parsing "[0", "e+", "-]" now properly returns an error. Strict mode now rejects missing exponents ("0e"). * Successfully return number objects at the top level even when they are followed by a "-", "." or "e". This makes parsing things like "123-45" behave consistently with things like "123xyz". Other changes ------------- * #589 - Detect broken RDRAND during initialization; also, fix segfault in the CPUID check. * #592 - Fix integer overflows to prevert out of bounds write on large input. * Protect against division by zero in linkhash, when creaed with zero size. * #602 - Fix json_parse_uint64() internal error checking, leaving the retval untouched in more failure cases. * #614 - Prevent truncation when custom double formatters insert extra \0's *** 0.14 (up to commit 9ed00a6, 2020/04/14) ========================================= Deprecated and removed features: -------------------------------- * bits.h has been removed * lh_abort() has been removed * lh_table_lookup() has been removed, use lh_table_lookup_ex() instead. * Remove TRUE and FALSE defines, use 1 and 0 instead. Build changes: -------------- ## Deprecated and removed features: * bits.h has been removed * lh_abort() has been removed * lh_table_lookup() has been removed, use lh_table_lookup_ex() instead. * Remove TRUE and FALSE defines, use 1 and 0 instead. * autoconf support, including autogen.sh, has been removed. See details about cmake, below. * With the addition of json_tokener_get_parse_end(), access to internal fields of json_tokener, as well as use of many other symbols and types in json_tokener.h, is deprecated now. * The use of Android.configure.mk to build for Android no longer works, and it is unknown how (or if) the new cmake-based build machinery can be used. * Reports of success, or pull requests to correct issues are welcome. ## Notable improvements and new features ### Builds and documentation * Build machinery has been switched to CMake. See README.md for details about how to build. * TL;DR: `mkdir build ; cd build ; cmake -DCMAKE_INSTALL_PREFIX=/some/path ../json-c ; make all test install` * To ease the transition, there is a `cmake-configure` wrapper that emulates the old autoconf-based configure script. * This has enabled improvements to the build on Windows system; also all public functions have been fixed to be properly exported. For best results, use Visual Studio 2015 or newer. * The json-c style guide has been updated to specify the use of clang-format, and all code has been reformatted. * Since many lines of code have trivial changes now, when using git blame, be sure to specify -w * Numerous improvements have been made to the documentation including function effects on refcounts, when passing a NULL is safe, and so on. ### json_tokener changes * Added a json_tokener_get_parse_end() function to replace direct access of tok->char_offset. * The char_offset field, and the rest of the json_tokener structure remain exposed for now, but expect a future release to hide it like is done with json_object_private.h * json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag to validate that input is UTF8. * If validation fails, json_tokener_get_error(tok) will return json_tokener_error_parse_utf8_string (see enum json_tokener_error). ### Other changes and additions * Add support for unsigned 64-bit integers, uint64_t, to gain one extra bit of magnitude for positive ints. * json_tokener will now parse values up to UINT64_MAX (18446744073709551615) * Existing methods returning int32_t or int64_t will cap out-of-range values at INT32_MAX or INT64_MAX, preserving existing behavior. * The implementation includes the possibility of easily extending this to larger sizes in the future. * A total of 7 new functions were added: * json_object_get_uint64 ( struct json_object const* jso ) * json_object_new_uint64 ( uint64_t i ) * json_object_set_uint64 ( struct json_object* jso, uint64_t new_value ) * json_parse_uint64 ( char const* buf, uint64_t* retval ) * See description of uint64 support, above. * json_tokener_get_parse_end ( struct json_tokener* tok ) * See details under "json_tokener changes", above. * json_object_from_fd_ex ( int fd, int in_depth ) * Allows the max nesting depth to be specified. * json_object_new_null ( ) * Simply returns NULL. Its use is not recommended. * The size of struct json_object has decreased from 96 bytes to 88 bytes. ### Testing * Many updates were made to test cases, increasing code coverage. * There is now a quick way (JSONC_TEST_TRACE=1) to turn on shell tracing in tests. * To run tests, use `make test`; the old "check" target no longer exists. ## Significant bug fixes For the full list of issues and pull requests since the previous release, please see issues_closed_for_0.14.md * [Issue #389](https://github.com/json-c/json-c/issues/389): Add an assert to explicitly crash when _ref_count is corrupted, instead of a later "double free" error. * [Issue #407](https://github.com/json-c/json-c/issues/407): fix incorrect casts in calls to ctype functions (isdigit and isspace) so we don't crash when asserts are enabled on certain platforms and characters > 128 are parsed. * [Issue #418](https://github.com/json-c/json-c/issues/418): Fix docs for json_util_from_fd and json_util_from_file to say that they return NULL on failures. * [Issue #422](https://github.com/json-c/json-c/issues/422): json_object.c:set errno in json_object_get_double() when called on a json_type_string object with bad content. * [Issue #453](https://github.com/json-c/json-c/issues/453): Fixed misalignment in JSON serialization when JSON_C_TO_STRING_SPACED and JSON_C_TO_STRING_PRETTY are used together. * [Issue #463](https://github.com/json-c/json-c/issues/463): fix newlocale() call to use LC_NUMERIC_MASK instead of LC_NUMERIC, and remove incorrect comment. * [Issue #486](https://github.com/json-c/json-c/issues/486): append a missing ".0" to negative double values to ensure they are serialized as floating point numbers. * [Issue #488](https://github.com/json-c/json-c/issues/488): use JSON_EXPORT on functions so they are properly exported on Windows. * [Issue #539](https://github.com/json-c/json-c/issues/539): use an internal-only serializer function in json_object_new_double_s() to avoid potential conflicts with user code that uses the json_object_userdata_to_json_string serializer. *** 0.13.1 (up to commit 0f814e5, 2018/03/04) ========================================= * Bump the major version of the .so library generated up to 4.0 to avoid conflicts because some downstream packagers of json-c had already done their own bump to ".so.3" for a much older 0.12 release. * Add const size_t json_c_object_sizeof() * Avoid invalid free (and thus a segfault) when ref_count gets < 0 * PR#394: fix handling of custom double formats that include a ".0" * Avoid uninitialized variable warnings in json_object_object_foreach * Issue #396: fix build for certain uClibc based systems. * Add a top level fuzz directory for fuzzers run by OSS-Fuzz 0.13 (up to commit 5dae561, 2017/11/29) ================================= This release, being three and a half years after the 0.12 branch (f84d9c), has quite a number of changes included. The following is a sampling of the most significant ones. Since the 0.12 release, 250 issues and pull requests have been closed. See issues_closed_for_0.13.md for a complete list. Deprecated and removed features: -------------------------------- * All internal use of bits.h has been eliminated. The file will be removed. Do not use: hexdigit(), error_ptr(), error_descrition() and it_error() * lh_abort() is deprecated. It will be removed. Behavior changes: ----------------- * Tighten the number parsing algorithm to raise errors instead of truncating the results. For example 12.3.4 or 2015-01-15, which now return null. See commit 99d8fc * Use size_t for array length and size. Platforms where sizeof(size_t) != sizeof(int) may not be backwards compatible See commits 45c56b, 92e9a5 and others. * Check for failue when allocating memory, returning NULL and errno=ENOMEM. See commit 2149a04. * Change json_object_object_add() return type from void to int, and will return -1 on failures, instead of exiting. (Note: this is not an ABI change) New features: ------------- * We're aiming to follow RFC 7159 now. * Add a couple of additional option to json_object_to_json_string_ext: JSON_C_TO_STRING_PRETTY_TAB JSON_C_TO_STRING_NOSLASHESCAPE * Add a json_object_object_add_ex() function to allow for performance improvements when certain constraints are known to be true. * Make serialization format of doubles configurable, in two different ways: Call json_object_set_serializer with json_object_double_to_json_string and a custom format on each double object, or Call json_c_set_serialization_double_format() to set a global or thread-wide format. * Add utility function for comparing json_objects - json_object_equal() * Add a way to copy entire object trees: json_object_deep_copy() * Add json_object_set_ function to modify the value of existing json_object's without the need to recreate them. Also add a json_object_int_inc function to adjust an int's value. * Add support for JSON pointer, RFC 6901. See json_pointer.h * Add a json_util_get_last_err() function to retrieve the string describing the cause of errors, instead of printing to stderr. * Add perllike hash function for strings, and json_global_set_string_hash() 8f8d03d * Add a json_c_visit() function to provide a way to iterate over a tree of json-c objects. Notable bug fixes and other improvements: ----------------------------------------- * Make reference increment and decrement atomic to allow passing json objects between threads. * Fix json_object_object_foreach to avoid uninitialized variable warnings. * Improve performance by removing unneeded data items from hashtable code and reducing duplicate hash computation. * Improve performance by storing small strings inside json_object * Improve performance of json_object_to_json_string by removing variadic printf. commit 9ff0f49 * Issue #371: fix parsing of "-Infinity", and avoid needlessly copying the input when doing so. * Fix stack buffer overflow in json_object_double_to_json_string_format() - commit 2c2deb87 * Fix various potential null ptr deref and int32 overflows * Issue #332: fix a long-standing bug in array_list_put_idx() where it would attempt to free previously free'd entries due to not checking the current array length. * Issue #195: use uselocale() instead of setlocale() in json_tokener to behave better in threaded environments. * Issue #275: fix out of bounds read when handling unicode surrogate pairs. * Ensure doubles that happen to be a whole number are emitted with ".0" - commit ca7a19 * PR#331: for Visual Studio, use a snprintf/vsnprintf wrapper that ensures the string is terminated. * Fix double to int cast overflow in json_object_get_int64. * Clamp double to int32 when narrowing in json_object_get_int. * Use strtoll() to parse ints - instead of sscanf * Miscellaneous smaller changes, including removing unused variables, fixing warning about uninitialized variables adding const qualifiers, reformatting code, etc... Build changes: -------------- * Add Appveyor and Travis build support * Switch to using CMake when building on Windows with Visual Studio. A dynamic .dll is generated instead of a .lib config.h is now generated, config.h.win32 should no longer be manually copied * Add support for MacOS through CMake too. * Enable silent build by default * Link against libm when needed * Add support for building with AddressSanitizer * Add support for building with Clang * Add a --enable-threading configure option, and only use the (slower) __sync_add_and_fetch()/__sync_sub_and_fetch() function when it is specified. List of new functions added: ---------------------------- ### json_object.h * array_list_bsearch() * array_list_del_idx() * json_object_to_json_string_length() * json_object_get_userdata() * json_object_set_userdata() * json_object_object_add_ex() * json_object_array_bsearch() * json_object_array_del_idx() * json_object_set_boolean() * json_object_set_int() * json_object_int_inc() * json_object_set_int64() * json_c_set_serialization_double_format() * json_object_double_to_json_string() * json_object_set_double() * json_object_set_string() * json_object_set_string_len() * json_object_equal() * json_object_deep_copy() ### json_pointer.h * json_pointer_get() * json_pointer_getf() * json_pointer_set() * json_pointer_setf() ### json_util.h * json_object_from_fd() * json_object_to_fd() * json_util_get_last_err() ### json_visit.h * json_c_visit() ### linkhash.h * json_global_set_string_hash() * lh_table_resize() ### printbuf.h * printbuf_strappend() 0.12.1 ====== * Minimal changes to address compile issues. 0.12 ==== * Address security issues: * CVE-2013-6371: hash collision denial of service * CVE-2013-6370: buffer overflow if size_t is larger than int * Avoid potential overflow in json_object_get_double * Eliminate the mc_abort() function and MC_ABORT macro. * Make the json_tokener_errors array local. It has been deprecated for a while, and json_tokener_error_desc() should be used instead. * change the floating point output format to %.17g so values with more than 6 digits show up in the output. * Remove the old libjson.so name compatibility support. The library is only created as libjson-c.so now and headers are only installed into the ${prefix}/json-c directory. * When supported by the linker, add the -Bsymbolic-functions flag. * Various changes to fix the build on MSVC. * Make strict mode more strict: * number must not start with 0 * no single-quote strings * no comments * trailing char not allowed * only allow lowercase literals * Added a json_object_new_double_s() convenience function to allow an exact string representation of a double to be specified when creating the object and use it in json_tokener_parse_ex() so a re-serialized object more exactly matches the input. * Add support NaN and Infinity 0.11 ==== * IMPORTANT: the name of the library has changed to libjson-c.so and the header files are now in include/json-c. The pkgconfig name has also changed from json to json-c. You should change your build to use appropriate -I and -l options. A compatibility shim is in place so builds using the old name will continue to work, but that will be removed in the next release. * Maximum recursion depth is now a runtime option. json_tokener_new() is provided for compatibility. json_tokener_new_ex(depth) * Include json_object_iterator.h in the installed headers. * Add support for building on Android. * Rewrite json_object_object_add to replace just the value if the key already exists so keys remain valid. * Make it safe to delete keys while iterating with the json_object_object_foreach macro. * Add a json_set_serializer() function to allow the string output of a json_object to be customized. * Make float parsing locale independent. * Add a json_tokener_set_flags() function and a JSON_TOKENER_STRICT flag. * Enable -Werror when building. * speed improvements to parsing 64-bit integers on systems with working sscanf * Add a json_object_object_length function. * Fix a bug (buffer overrun) when expanding arrays to more than 64 entries. 0.10 ==== * Add a json_object_to_json_string_ext() function to allow output to be formatted in a more human readable form. * Add json_object_object_get_ex(), a NULL-safe get object method, to be able to distinguish between a key not present and the value being NULL. * Add an alternative iterator implementation, see json_object_iterator.h * Make json_object_iter public to enable external use of the json_object_object_foreachC macro. * Add a printbuf_memset() function to provide an effecient way to set and append things like whitespace indentation. * Adjust json_object_is_type and json_object_get_type so they return json_type_null for NULL objects and handle NULL passed to json_objct_object_get(). * Rename boolean type to json_bool. * Fix various compile issues for Visual Studio and MinGW. * Allow json_tokener_parse_ex() to be re-used to parse multiple object. Also, fix some parsing issues with capitalized hexadecimal numbers and number in E notation. * Add json_tokener_get_error() and json_tokener_error_desc() to better encapsulate the process of retrieving errors while parsing. * Various improvements to the documentation of many functions. * Add new json_object_array_sort() function. * Fix a bug in json_object_get_int(), which would incorrectly return 0 when called on a string type object. Eric Haszlakiewicz * Add a json_type_to_name() function. Eric Haszlakiewicz * Add a json_tokener_parse_verbose() function. Jehiah Czebotar * Improve support for null bytes within JSON strings. Jehiah Czebotar * Fix file descriptor leak if memory allocation fails in json_util Zachary Blair, zack_blair at hotmail dot com * Add int64 support.

JSON-C - A JSON implementation in C

Overview

JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON formatted strings and parse JSON formatted strings back into the C representation of JSON objects. It aims to conform to RFC 7159.

Building

To setup JSON-C to build on your system please run configure and make.

If you are on Win32 cmake is required, generally:

  • mkdir build
  • cd build
  • cmake ..
  • msbuild "json-c.vcxproj" /m /verbosity:normal /p:OutDir=lib\
  • Or, open the project in Visual Studio

Documentation

It aims to conform to [RFC 7159](https://tools.ietf.org/html/rfc7159). Building on Unix with `git`, `gcc` and `cmake` -------------------------------------------------- Home page for json-c: https://github.com/json-c/json-c/wiki ### Prerequisites: - `gcc`, `clang`, or another C compiler - cmake>=2.8, >=3.16 recommended To generate docs you'll also need: - `doxygen>=1.8.13` If you are on a relatively modern system, you'll likely be able to install the prerequisites using your OS's packaging system. ### Install using apt (e.g. Ubuntu 16.04.2 LTS) ```sh sudo apt install git sudo apt install cmake sudo apt install doxygen # optional sudo apt install valgrind # optional ``` ### Build instructions: `json-c` GitHub repo: https://github.com/json-c/json-c ```sh $ git clone https://github.com/json-c/json-c.git $ mkdir json-c-build $ cd json-c-build $ cmake ../json-c # See CMake section below for custom arguments ``` Note: it's also possible to put your build directory inside the json-c source directory, or even not use a separate build directory at all, but certain things might not work quite right (notably, `make distcheck`) Then: ```sh $ make $ make test $ make USE_VALGRIND=0 test # optionally skip using valgrind $ make install ``` ### Generating documentation with Doxygen: The libray documentation can be generated directly from the source codes using Doxygen tool: ```sh # in build directory make doc google-chrome doc/html/index.html ``` CMake Options -------------------- The json-c library is built with [CMake](https://cmake.org/cmake-tutorial/), which can take a few options. Variable | Type | Description -----------------------------|--------|-------------- CMAKE_INSTALL_PREFIX | String | The install location. CMAKE_BUILD_TYPE | String | Defaults to "debug". BUILD_SHARED_LIBS | Bool | The default build generates a dynamic (dll/so) library. Set this to OFF to create a static library only. BUILD_STATIC_LIBS | Bool | The default build generates a static (lib/a) library. Set this to OFF to create a shared library only. DISABLE_STATIC_FPIC | Bool | The default builds position independent code. Set this to OFF to create a shared library only. DISABLE_BSYMBOLIC | Bool | Disable use of -Bsymbolic-functions. DISABLE_THREAD_LOCAL_STORAGE | Bool | Disable use of Thread-Local Storage (HAVE___THREAD). DISABLE_WERROR | Bool | Disable use of -Werror. ENABLE_RDRAND | Bool | Enable RDRAND Hardware RNG Hash Seed. ENABLE_THREADING | Bool | Enable partial threading support. OVERRIDE_GET_RANDOM_SEED | String | A block of code to use instead of the default implementation of json_c_get_random_seed(), e.g. on embedded platforms where not even the fallback to time() works. Must be a single line. Pass these options as `-D` on CMake's command-line. ```sh # build a static library only cmake -DBUILD_SHARED_LIBS=OFF .. ``` ### Building with partial threading support Although json-c does not support fully multi-threaded access to object trees, it has some code to help make its use in threaded programs a bit safer. Currently, this is limited to using atomic operations for json_object_get() and json_object_put(). Since this may have a performance impact, of at least 3x slower according to https://stackoverflow.com/a/11609063, it is disabled by default. You may turn it on by adjusting your cmake command with: -DENABLE_THREADING=ON Separately, the default hash function used for object field keys, lh_char_hash, uses a compare-and-swap operation to ensure the random seed is only generated once. Because this is a one-time operation, it is always compiled in when the compare-and-swap operation is available. ### cmake-configure wrapper script For those familiar with the old autoconf/autogen.sh/configure method, there is a `cmake-configure` wrapper script to ease the transition to cmake. ```sh mkdir build cd build ../cmake-configure --prefix=/some/install/path make ``` cmake-configure can take a few options. | options | Description| | ---- | ---- | | prefix=PREFIX | install architecture-independent files in PREFIX | | enable-threading | Enable code to support partly multi-threaded use | | enable-rdrand | Enable RDRAND Hardware RNG Hash Seed generation on supported x86/x64 platforms. | | enable-shared | build shared libraries [default=yes] | | enable-static | build static libraries [default=yes] | | disable-Bsymbolic | Avoid linking with -Bsymbolic-function | | disable-werror | Avoid treating compiler warnings as fatal errors | Testing: ---------- By default, if valgrind is available running tests uses it. That can slow the tests down considerably, so to disable it use: ```sh export USE_VALGRIND=0 ``` To run tests a separate build directory is recommended: ```sh mkdir build-test cd build-test # VALGRIND=1 causes -DVALGRIND=1 to be passed when compiling code # which uses slightly slower, but valgrind-safe code. VALGRIND=1 cmake .. make make test # By default, if valgrind is available running tests uses it. make USE_VALGRIND=0 test # optionally skip using valgrind ``` If a test fails, check `Testing/Temporary/LastTest.log`, `tests/testSubDir/${testname}/${testname}.vg.out`, and other similar files. If there is insufficient output try: ```sh VERBOSE=1 make test ``` or ```sh JSONC_TEST_TRACE=1 make test ``` and check the log files again. Building on Unix and Windows with `vcpkg` -------------------------------------------------- You can download and install JSON-C using the [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager: git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install vcpkg install json-c The JSON-C port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository. Linking to `libjson-c` ---------------------- If your system has `pkgconfig`, then you can just add this to your `makefile`: ```make CFLAGS += $(shell pkg-config --cflags json-c) LDFLAGS += $(shell pkg-config --libs json-c) ``` Without `pkgconfig`, you would do something like this: ```make JSON_C_DIR=/path/to/json_c/install CFLAGS += -I$(JSON_C_DIR)/include/json-c LDFLAGS+= -L$(JSON_C_DIR)/lib -ljson-c ``` Using json-c ------------ To use json-c you can either include json.h, or preferrably, one of the following more specific header files: * json_object.h - Core types and methods. * json_tokener.h - Methods for parsing and serializing json-c object trees. * json_pointer.h - JSON Pointer (RFC 6901) implementation for retrieving objects from a json-c object tree. * json_object_iterator.h - Methods for iterating over single json_object instances. (See also `json_object_object_foreach()` in json_object.h) * json_visit.h - Methods for walking a tree of json-c objects. * json_util.h - Miscelleanous utility functions. For a full list of headers see [files.html](http://json-c.github.io/json-c/json-c-current-release/doc/html/files.html) The primary type in json-c is json_object. It describes a reference counted tree of json objects which are created by either parsing text with a json_tokener (i.e. `json_tokener_parse_ex()`), or by creating (with `json_object_new_object()`, `json_object_new_int()`, etc...) and adding (with `json_object_object_add()`, `json_object_array_add()`, etc...) them individually. Typically, every object in the tree will have one reference, from it's parent. When you are done with the tree of objects, you call json_object_put() on just the root object to free it, which recurses down through any child objects calling json_object_put() on each one of those in turn. You can get a reference to a single child (`json_object_object_get()` or `json_object_array_get_idx()`) and use that object as long as its parent is valid. If you need a child object to live longer than its parent, you can increment the child's refcount (`json_object_get()`) to allow it to survive the parent being freed or it being removed from its parent (`json_object_object_del()` or `json_object_array_del_idx()`) When parsing text, the json_tokener object is independent from the json_object that it returns. It can be allocated (`json_tokener_new()`) used ones or multiple times (`json_tokener_parse_ex()`, and freed (`json_tokener_free()`) while the json_object objects live on. A json_object tree can be serialized back into a string with `json_object_to_json_string_ext()`. The string that is returned is only valid until the next "to_json_string" call on that same object. Also, it is freed when the json_object is freed. json-c-json-c-0.15-20200726/RELEASE_CHECKLIST.txt000066400000000000000000000113201370731665100201370ustar00rootroot00000000000000 # Release checklist: ## Pre-release tasks * Figure out whether a release is worthwhile to do. * Analyze the previous release branch to see if anything should have been applied to master. * Collect changes and assemble tentative release notes. * Identify previous release branch point * Check commit logs between previous branch point and now for notable changes worth mentioning * Create a new issues_closed_for_X.Y.md file * Include notable entries from here in the release notes. * Analyze APIs between previous release branch and master to produce list of changes (added/removed/updated funcs, etc...), and detect backwards compat issues. * https://github.com/lvc/abi-compliance-checker * If the new release is not backwards compatible, then this is a MAJOR release. * Mention removed features in ChangeLog * Consider re-adding backwards compatible support, through symbol aliases and appropriate entries in json-c.sym * Update the AUTHORS file * Exclude mentioning changes that have already been included in a point release of the previous release branch. * Update ChangeLog with relevant notes before branching. * Check that the compile works on Linux - automatic through Travis * Check that the compile works on NetBSD * Check that the compile works on Windows - automatic through AppVeyor ## Release creation Start creating the new release: release=0.15 git clone https://github.com/json-c/json-c json-c-${release} mkdir distcheck cd distcheck # Note, the build directory *must* be entirely separate from # the source tree for distcheck to work properly. cmake ../json-c-${release} make distcheck cd .. Make any fixes/changes *before* branching. cd json-c-${release} git branch json-c-${release} git checkout json-c-${release} ------------ Using ${release}: Update the version in json_c_version.h Update the version in CMakeLists.txt (VERSION in the project(...) line) Update the version in config.h.win32 (several places) Update the set_target_properties() line in CmakeLists.txt to set the shared library version. Generally, unless we're doing a major release, change: VERSION x.y.z to VERSION x.y+1.z git commit -a -m "Bump version to ${release}" If we're doing a major release (SONAME bump), also bump the version of ALL symbols in json-c.sym.

When changing the style, commit that separately from other changes. For new code and major changes to a function, switch to the official json-c style. Official json-c style: Aim for readability, not strict conformance to fixed style rules. Formatting is tab based; previous attempts at proper alignment with spaces for continuation lines have been abandoned in favor of the convenience of using clang-format. Refer to the .clang-format file for details, and run the tool before commit: clang-format -i somefile.c foo.h For sections of code that would be significantly negatively impacted, surround them with magic comments to disable formatting: /* clang-format off */ ...code... /* clang-format on */ Naming: Words within function and variable names are separated with underscores. Avoid camel case. Prefer longer, more descriptive names, but not excessively so. No single letter variable names. Other: Variables should be defined for the smallest scope needed. Functions should be defined static when possible. When possible, avoid exposing internals in the public API. json-c-json-c-0.15-20200726/apps/000077500000000000000000000000001370731665100156735ustar00rootroot00000000000000json-c-json-c-0.15-20200726/apps/CMakeLists.txt000066400000000000000000000104651370731665100204410ustar00rootroot00000000000000 cmake_minimum_required(VERSION 2.8) # see ../CMakeLists.txt for why 2.8 if(POLICY CMP0075) cmake_policy(SET CMP0075 NEW) endif() include(CheckSymbolExists) include(CheckIncludeFile) include(CMakePackageConfigHelpers) # First, sort out whether we're running inside a json-c build, # or standalone, such as part of a benchmark build. if ("${PROJECT_NAME}" STREQUAL "json-c") # Part of an overall json-c build set(APPS_LINK_LIBS "${PROJECT_NAME}") # We know we have this in our current sources: set(HAVE_JSON_TOKENER_GET_PARSE_END) else() # Standalone mode, using an already installed json-c library, somewhere. # The path to the json-c install must be specified with -DCMAKE_PREFIX_PATH=... project(apps) find_package(PkgConfig) # PkgConfig is supposed to include CMAKE_PREFIX_PATH in the PKG_CONFIG_PATH # that's used when running pkg-config, but it just doesn't work :( # https://gitlab.kitware.com/cmake/cmake/issues/18150 #set(PKG_CONFIG_USE_CMAKE_PREFIX_PATH True) # Instead, we handle it explicitly here and update PKG_CONFIG_PATH ourselves. if (NOT CMAKE_PREFIX_PATH) message(FATAL_ERROR "Please specify -DCMAKE_PREFIX_PATH=... when running cmake.") endif() # Note: find_file isn't recursive :( find_file(PC_FILE_PATH "json-c.pc" PATHS "${CMAKE_PREFIX_PATH}/lib64" "${CMAKE_PREFIX_PATH}/lib" PATH_SUFFIXES "pkgconfig" NO_DEFAULT_PATH) get_filename_component(PC_DIR_PATH "${PC_FILE_PATH}" DIRECTORY) set(ENV{PKG_CONFIG_PATH} "$ENV{PKG_CONFIG_PATH}:${PC_DIR_PATH}") message(STATUS "PC_FILE_PATH=${PC_FILE_PATH}") message(STATUS "PC_DIR_PATH=${PC_DIR_PATH}") pkg_check_modules(PC_JSONC json-c) if (PC_JSONC_FOUND) message(STATUS "Found json-c using pkg-config: ${PC_JSONC_PREFIX}") message(STATUS " PC_JSONC_INCLUDE_DIRS=${PC_JSONC_INCLUDE_DIRS}") message(STATUS " PC_JSONC_LIBRARIES=${PC_JSONC_LIBRARIES}") message(STATUS " PC_JSONC_LIBRARY_DIRS=${PC_JSONC_LIBRARY_DIRS}") link_directories(${PC_JSONC_LIBRARY_DIRS}) include_directories(${PC_JSONC_INCLUDE_DIRS}) # for target_link_libraries(...) set(APPS_INCLUDE_DIRS ${PC_JSONC_INCLUDE_DIRS}) set(APPS_LINK_DIRS ${PC_JSONC_LIBRARY_DIRS}) set(APPS_LINK_LIBS ${PC_JSONC_LIBRARIES}) else() message(STATUS "Using find_package to locate json-c") # Note: find_package needs CMAKE_PREFIX_PATH set appropriately. # XXX json-c's installed cmake files don't actually set up what's # needed to use find_package() by itself, so we're just using it # to confirm the top of the install location. find_package(json-c CONFIG) # sets json-c_DIR # Assume json-c-config.cmake is in lib64/cmake/json-c/ get_filename_component(json-c_TOP "${json-c_DIR}/../../.."

OPTIMIZE_OUTPUT_VHDL = NO # Doxygen selects the parser to use depending on the extension of the files it # parses. With this tag you can assign which parser to use for a given # extension. Doxygen has a built-in mapping, but you can override or extend it # using this tag. The format is ext=language, where ext is a file extension, and # language is one of the parsers supported by doxygen: IDL, Java, Javascript, # C#, C, C++, D, PHP, Objective-C, Python, Fortran (fixed format Fortran: # FortranFixed, free formatted Fortran: FortranFree, unknown formatted Fortran: # Fortran. In the later case the parser tries to guess whether the code is fixed # or free formatted code, this is the default for Fortran type files), VHDL. For # instance to make doxygen treat .inc files as Fortran files (default is PHP), # and .f files as C (default is Fortran), use: inc=Fortran f=C. # # Note For files without extension you can use no_extension as a placeholder. # # Note that for custom extensions you also need to set FILE_PATTERNS otherwise # the files are not read by doxygen. EXTENSION_MAPPING = # If the MARKDOWN_SUPPORT tag is enabled then doxygen pre-processes all comments # according to the Markdown format, which allows for more readable # documentation. See http://daringfireball.net/projects/markdown/ for details. # The output of markdown processing is further processed by doxygen, so you can # mix doxygen, HTML, and XML commands with Markdown formatting. Disable only in # case of backward compatibilities issues. # The default value is: YES. MARKDOWN_SUPPORT = YES # When enabled doxygen tries to link words that correspond to documented # classes, or namespaces to their corresponding documentation. Such a link can # be prevented in individual cases by by putting a % sign in front of the word # or globally by setting AUTOLINK_SUPPORT to NO. # The default value is: YES. AUTOLINK_SUPPORT = YES # If you use STL classes (i.e. std::string, std::vector, etc.) but do not want # to include (a tag file for) the STL sources as input, then you should set this # tag to YES in order to let doxygen match functions declarations and # definitions whose arguments contain STL classes (e.g. func(std::string); # versus func(std::string) {}). This also make the inheritance and collaboration # diagrams that involve STL classes more complete and accurate. # The default value is: NO. BUILTIN_STL_SUPPORT = NO # If you use Microsoft's C++/CLI language, you should set this option to YES to # enable parsing support. # The default value is: NO. CPP_CLI_SUPPORT = NO # Set the SIP_SUPPORT tag to YES if your project consists of sip (see: # http://www.riverbankcomputing.co.uk/software/sip/intro) sources only.

SIP_SUPPORT = NO # For Microsoft's IDL there are propget and propput attributes to indicate # getter and setter methods for a property. Setting this option to YES will make # doxygen to replace the get and set methods by a property in the documentation. # This will only work if the methods are indeed getting or setting a simple # type.

Allocate an array_list of the default size (32).

Deprecated:
Use array_list_new2() instead.
struct array_list* array_list_new2 ( array_list_free_fn *  free_fn,
int  initial_size 
)
read

Allocate an array_list of the desired size.

If possible, the size should be chosen to closely match the actual number of elements expected to be used. If the exact size is unknown, there are tradeoffs to be made:

  • too small - the array_list code will need to call realloc() more often (which might incur an additional memory copy).
  • too large - will waste memory, but that can be mitigated by calling array_list_shrink() once the final size is known.

File List
Here is a list of all files with brief descriptions:
[detail level 12]
\-json-c-0.15
 o*arraylist.hInternal methods for working with json_type_array objects. Although this is exposed by the json_object_get_array() method, it is not recommended for direct use
 o*json.hA convenience header that may be included instead of other individual ones
 o*json_c_version.hMethods for retrieving the json-c version
 o*json_inttypes.hDo not use, json-c internal, may be changed or removed at any time
 o*json_object.hCore json-c API. Start here, or with json_tokener.h
 o*json_object_iterator.hAn API for iterating over json_type_object objects, styled to be familiar to C++ programmers. Unlike json_object_object_foreach() and json_object_object_foreachC(), this avoids the need to expose json-c internals like lh_entry
 o*json_pointer.hJSON Pointer (RFC 6901) implementation for retrieving objects from a json-c object tree
 o*json_tokener.hMethods to parse an input string into a tree of json_object objects
 o*json_types.hBasic types used in a few places in json-c, but you should include "json_object.h" instead
 o*json_util.hMiscllaneous utility functions and macros
 o*json_visit.hMethods for walking a tree of objects
 o*linkhash.hInternal methods for working with json_type_object objects. Although this is exposed by the json_object_get_object() function and within the json_object_iter type, it is not recommended for direct use
 \*printbuf.hInternal string buffer handing. Unless you're writing a json_object_to_json_string_fn implementation for use with json_object_set_serializer() direct use of this is not recommended

JSON-C - A JSON implementation in C

Build Status

Test Status

JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON formatted strings and parse JSON formatted strings back into the C representation of JSON objects. It aims to conform to RFC 7159.

Building on Unix with git, gcc and cmake

Home page for json-c: https://github.com/json-c/json-c/wiki

Prerequisites:

  • gcc, clang, or another C compiler
  • cmake>=2.8, >=3.16 recommended

To generate docs you'll also need:

  • doxygen>=1.8.13

If you are on a relatively modern system, you'll likely be able to install the prerequisites using your OS's packaging system.

Install using apt (e.g. Ubuntu 16.04.2 LTS)

sudo apt install git
sudo apt install cmake
sudo apt install doxygen  # optional
sudo apt install valgrind # optional

Build instructions:

json-c GitHub repo: https://github.com/json-c/json-c 

$ git clone https://github.com/json-c/json-c.git
$ mkdir json-c-build
$ cd json-c-build
$ cmake ../json-c   # See CMake section below for custom arguments

Note: it's also possible to put your build directory inside the json-c source directory, or even not use a separate build directory at all, but certain things might not work quite right (notably, make distcheck)

Then: 

$ make
$ make test
$ make USE_VALGRIND=0 test   # optionally skip using valgrind
$ make install

CMake Options

The json-c library is built with CMake, which can take a few options.

Variable Type Description
CMAKE_INSTALL_PREFIX String The install location.
CMAKE_BUILD_TYPE String Defaults to "debug".
BUILD_SHARED_LIBS Bool The default build generates a dynamic (dll/so) library. Set this to OFF to create a static library only.
BUILD_STATIC_LIBS Bool The default build generates a static (lib/a) library. Set this to OFF to create a shared library only.
DISABLE_STATIC_FPIC Bool The default builds position independent code. Set this to OFF to create a shared library only.
DISABLE_BSYMBOLIC Bool Disable use of -Bsymbolic-functions.
DISABLE_THREAD_LOCAL_STORAGE Bool Disable use of Thread-Local Storage (HAVE___THREAD).
DISABLE_WERROR Bool Disable use of -Werror.
ENABLE_RDRAND Bool Enable RDRAND Hardware RNG Hash Seed.
ENABLE_THREADING Bool Enable partial threading support.
OVERRIDE_GET_RANDOM_SEED String A block of code to use instead of the default implementation of json_c_get_random_seed(), e.g. on embedded platforms where not even the fallback to time() works. Must be a single line.

Pass these options as -D on CMake's command-line. 

# build a static library only
cmake -DBUILD_SHARED_LIBS=OFF ..

Building with partial threading support

Although json-c does not support fully multi-threaded access to object trees, it has some code to help make its use in threaded programs a bit safer. Currently, this is limited to using atomic operations for json_object_get() and json_object_put().

Since this may have a performance impact, of at least 3x slower according to https://stackoverflow.com/a/11609063, it is disabled by default. You may turn it on by adjusting your cmake command with: -DENABLE_THREADING=ON

Separately, the default hash function used for object field keys, lh_char_hash, uses a compare-and-swap operation to ensure the random seed is only generated once. Because this is a one-time operation, it is always compiled in when the compare-and-swap operation is available.

cmake-configure wrapper script

For those familiar with the old autoconf/autogen.sh/configure method, there is a cmake-configure wrapper script to ease the transition to cmake. 

mkdir build
cd build
../cmake-configure --prefix=/some/install/path
make

cmake-configure can take a few options.

options Description
prefix=PREFIX install architecture-independent files in PREFIX
enable-threading Enable code to support partly multi-threaded use
enable-rdrand Enable RDRAND Hardware RNG Hash Seed generation on supported x86/x64 platforms.
enable-shared build shared libraries [default=yes]
enable-static build static libraries [default=yes]
disable-Bsymbolic Avoid linking with -Bsymbolic-function
disable-werror Avoid treating compiler warnings as fatal errors

Testing:

By default, if valgrind is available running tests uses it. That can slow the tests down considerably, so to disable it use: 

export USE_VALGRIND=0

To run tests a separate build directory is recommended: 

mkdir build-test
cd build-test
# VALGRIND=1 causes -DVALGRIND=1 to be passed when compiling code
# which uses slightly slower, but valgrind-safe code.
VALGRIND=1 cmake ..
make

make test
# By default, if valgrind is available running tests uses it.
make USE_VALGRIND=0 test   # optionally skip using valgrind

If a test fails, check Testing/Temporary/LastTest.log, tests/testSubDir/${testname}/${testname}.vg.out, and other similar files. If there is insufficient output try: 

VERBOSE=1 make test

or 

JSONC_TEST_TRACE=1 make test

and check the log files again.

Building on Unix and Windows with vcpkg

You can download and install JSON-C using the vcpkg dependency manager: 

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install json-c

The JSON-C port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.

Linking to libjson-c

If your system has pkgconfig, then you can just add this to your makefile: 

CFLAGS += $(shell pkg-config --cflags json-c)
LDFLAGS += $(shell pkg-config --libs json-c)

Without pkgconfig, you would do something like this: 

JSON_C_DIR=/path/to/json_c/install
CFLAGS += -I$(JSON_C_DIR)/include/json-c
LDFLAGS+= -L$(JSON_C_DIR)/lib -ljson-c

Using json-c

To use json-c you can either include json.h, or preferrably, one of the following more specific header files:

For a full list of headers see files.html

The primary type in json-c is json_object. It describes a reference counted tree of json objects which are created by either parsing text with a json_tokener (i.e. json_tokener_parse_ex()), or by creating (with json_object_new_object(), json_object_new_int(), etc...) and adding (with json_object_object_add(), json_object_array_add(), etc...) them individually. Typically, every object in the tree will have one reference, from it's parent. When you are done with the tree of objects, you call json_object_put() on just the root object to free it, which recurses down through any child objects calling json_object_put() on each one of those in turn.

You can get a reference to a single child (json_object_object_get() or json_object_array_get_idx()) and use that object as long as its parent is valid. If you need a child object to live longer than its parent, you can increment the child's refcount (json_object_get()) to allow it to survive the parent being freed or it being removed from its parent (json_object_object_del() or json_object_array_del_idx())

When parsing text, the json_tokener object is independent from the json_object that it returns. It can be allocated (json_tokener_new()) used ones or multiple times (json_tokener_parse_ex(), and freed (json_tokener_free()) while the json_object objects live on.

A json_object tree can be serialized back into a string with json_object_to_json_string_ext(). The string that is returned is only valid until the next "to_json_string" call on that same object. Also, it is freed when the json_object is freed.

Macro Definition Documentation

#define JSON_C_CONST_FUNCTION (   func )    func
#define JSON_C_OBJECT_ADD_KEY_IS_NEW   (1 << 1)

A flag for the json_object_object_add_ex function which causes the value to be added without a check if it already exists. Note: it is the responsibility of the caller to ensure that no key is added multiple times. If this is done, results are unpredictable. While this option is somewhat dangerous, it permits potentially large performance savings in code that knows for sure the key values are unique (e.g. because the code adds a well-known set of constant key values).

#define JSON_C_OBJECT_KEY_IS_CONSTANT   (1 << 2)

A flag for the json_object_object_add_ex function which flags the key as being constant memory. This means that the key will NOT be copied via strdup(), resulting in a potentially huge performance win (malloc, strdup and free are usually performance hogs). It is acceptable to use this flag for keys in non-constant memory blocks if the caller ensure that the memory holding the key lives longer than the corresponding json object. However, this is somewhat dangerous and should only be done if really justified. The general use-case for this flag is cases where the key is given as a real constant value in the function call, e.g. as in json_object_object_add_ex(obj, "ip", json, JSON_C_OBJECT_KEY_IS_CONSTANT);

#define JSON_C_OPTION_GLOBAL   (0)

Set the global value of an option, which will apply to all current and future threads that have not set a thread-local value.

See Also
json_c_set_serialization_double_format
#define JSON_C_OPTION_THREAD   (1)

Set a thread-local value of an option, overriding the global value. This will fail if json-c is not compiled with threading enabled, and with the __thread specifier (or equivalent) available.

See Also
json_c_set_serialization_double_format
#define JSON_C_TO_STRING_NOSLASHESCAPE   (1 << 4)

Don't escape forward slashes.

#define JSON_C_TO_STRING_NOZERO   (1 << 2)

A flag to drop trailing zero for float values

#define JSON_C_TO_STRING_PLAIN   0

A flag for the json_object_to_json_string_ext() and json_object_to_file_ext() functions which causes the output to have no extra whitespace or formatting applied.

#define JSON_C_TO_STRING_PRETTY   (1 << 1)

A flag for the json_object_to_json_string_ext() and json_object_to_file_ext() functions which causes the output to be formatted.

See the "Two Space Tab" option at http://jsonformatter.curiousconcept.com/ for an example of the format.

#define JSON_C_TO_STRING_PRETTY_TAB   (1 << 3)

A flag for the json_object_to_json_string_ext() and json_object_to_file_ext() functions which causes the output to be formatted.

Instead of a "Two Space Tab" this gives a single tab character.

#define JSON_C_TO_STRING_SPACED   (1 << 0)

A flag for the json_object_to_json_string_ext() and json_object_to_file_ext() functions which causes the output to have minimal whitespace inserted to make things slightly more readable.

#define JSON_OBJECT_DEF_HASH_ENTRIES   16
#define json_object_object_foreach (   obj,
  key,
  val 
)
Value:
char *key = NULL; \
struct json_object *val = NULL; \
struct lh_entry *entry##key; \
struct lh_entry *entry_next##key = NULL; \
for (entry##key = json_object_get_object(obj)->head; \
(entry##key ? (key = (char *)lh_entry_k(entry##key), \
val = (struct json_object *)lh_entry_v(entry##key), \
entry_next##key = entry##key->next, entry##key) \
: 0); \
entry##key = entry_next##key)

Iterate through all keys and values of an object.

Adding keys to the object while iterating is NOT allowed.

Deleting an existing key, or replacing an existing key with a new value IS allowed.

Parameters
objthe json_object instance
keythe local name for the char* key variable defined in the body
valthe local name for the json_object* object variable defined in the body
#define json_object_object_foreachC (   obj,
  iter 
)
Value:
for (iter.entry = json_object_get_object(obj)->head; \
(iter.entry ? (iter.key = (char *)lh_entry_k(iter.entry), \
iter.val = (struct json_object *)lh_entry_v(iter.entry), iter.entry) \
: 0); \
iter.entry = iter.entry->next)

Iterate through all keys and values of an object (ANSI C Safe)

Parameters
objthe json_object instance
iterthe object iterator, use type json_object_iter

Typedef Documentation

typedef int( json_c_shallow_copy_fn)(json_object *src, json_object *parent, const char *key, size_t index, json_object **dst)

Perform a shallow copy of src into *dst as part of an overall json_object_deep_copy().

If src is part of a containing object or array, parent will be non-NULL, and key or index will be provided. When shallow_copy is called *dst will be NULL, and must be non-NULL when it returns. src will never be NULL.

If shallow_copy sets the serializer on an object, return 2 to indicate to json_object_deep_copy that it should not attempt to use the standard userdata copy function.

Returns
On success 1 or 2, -1 on errors

Function Documentation

JSON_C_CONST_FUNCTION ( JSON_EXPORT size_t   json_c_object_sizeofvoid)

Get the sizeof (struct json_object).

Returns
a size_t with the sizeof (struct json_object)
JSON_EXPORT int json_c_set_serialization_double_format ( const char *  double_format,
int  global_or_thread 
)

Set a global or thread-local json-c option, depending on whether JSON_C_OPTION_GLOBAL or JSON_C_OPTION_THREAD is passed. Thread-local options default to undefined, and inherit from the global value, even if the global value is changed after the thread is created. Attempting to set thread-local options when threading is not compiled in will result in an error. Be sure to check the return value.

double_format is a "%g" printf format, such as "%.20g"

Returns
-1 on errors, 0 on success.
JSON_EXPORT int json_object_array_add ( struct json_object *  obj,
struct json_object *  val 
)

Add an element to the end of a json_object of type json_type_array

The reference count will not be incremented. This is to make adding fields to objects in code more compact. If you want to retain a reference to an added object you must wrap the passed object with json_object_get

Parameters
objthe json_object instance
valthe json_object to be added
JSON_EXPORT struct json_object* json_object_array_bsearch ( const struct json_object *  key,
const struct json_object *  jso,
int(*)(const void *, const void *)  sort_fn 
)
read

Binary search a sorted array for a specified key object.

It depends on your compare function what's sufficient as a key. Usually you create some dummy object with the parameter compared in it, to identify the right item you're actually looking for.

See Also
json_object_array_sort() for hints on the compare function.
Parameters
keya dummy json_object with the right key
jsothe array object we're searching
sort_fnthe sort/compare function
Returns
the wanted json_object instance
JSON_EXPORT int json_object_array_del_idx ( struct json_object *  obj,
size_t  idx,
size_t  count 
)

Delete an elements from a specified index in an array (a json_object of type json_type_array)

The reference count will be decremented for each of the deleted objects. If there are no more owners of an element that is being deleted, then the value is freed. Otherwise, the reference to the value will remain in memory.

Parameters
objthe json_object instance
idxthe index to start deleting elements at
countthe number of elements to delete
Returns
0 if the elements were successfully deleted
JSON_EXPORT struct json_object* json_object_array_get_idx ( const struct json_object *  obj,
size_t  idx 
)
read

Get the element at specified index of array obj (which must be a json_object of type json_type_array)

No reference counts will be changed, and ownership of the returned object remains with obj. See json_object_object_get() for additional implications of this behavior.

Calling this with anything other than a json_type_array will trigger an assert.

Parameters
objthe json_object instance
idxthe index to get the element at
Returns
the json_object at the specified index (or NULL)
JSON_EXPORT size_t json_object_array_length ( const struct json_object *  obj)

Get the length of a json_object of type json_type_array

Parameters
objthe json_object instance
Returns
an int
JSON_EXPORT int json_object_array_put_idx ( struct json_object *  obj,
size_t  idx,
struct json_object *  val 
)

Insert or replace an element at a specified index in an array (a json_object of type json_type_array)

The reference count will not be incremented. This is to make adding fields to objects in code more compact. If you want to retain a reference to an added object you must wrap the passed object with json_object_get

The reference count of a replaced object will be decremented.

The array size will be automatically be expanded to the size of the index if the index is larger than the current size.

Parameters
objthe json_object instance
idxthe index to insert the element at
valthe json_object to be added
JSON_EXPORT int json_object_array_shrink ( struct json_object *  jso,
int  empty_slots 
)

Shrink the internal memory allocation of the array to just enough to fit the number of elements in it, plus empty_slots.

Parameters
jsothe json_object instance, must be json_type_array
empty_slotsthe number of empty slots to leave allocated
JSON_EXPORT void json_object_array_sort ( struct json_object *  jso,
int(*)(const void *, const void *)  sort_fn 
)

Sorts the elements of jso of type json_type_array

Pointers to the json_object pointers will be passed as the two arguments to sort_fn

Parameters
jsothe json_object instance
sort_fna sorting function
JSON_EXPORT int json_object_deep_copy ( struct json_object *  src,
struct json_object **  dst,
json_c_shallow_copy_fn *  shallow_copy 
)

Copy the contents of the JSON object. The destination object must be initialized to NULL, to make sure this function won't overwrite an existing JSON object.

This does roughly the same thing as json_tokener_parse(json_object_get_string(src)).

Parameters
srcsource JSON object whose contents will be copied
dstpointer to the destination object where the contents of src; make sure this pointer is initialized to NULL
shallow_copyan optional function to copy individual objects, needed when custom serializers are in use. See also json_object set_serializer.
Returns
0 if the copy went well, -1 if an error occured during copy or if the destination pointer is non-NULL
JSON_EXPORT int json_object_double_to_json_string ( struct json_object *  jso,
struct printbuf *  pb,
int  level,
int  flags 
)

Serialize a json_object of type json_type_double to a string.

This function isn't meant to be called directly. Instead, you can set a custom format string for the serialization of this double using the following call (where "%.17g" actually is the default):

jso = json_object_new_double(d);
json_object_set_serializer(jso, json_object_double_to_json_string,
"%.17g", NULL);
See Also
printf(3) man page for format strings
Parameters
jsoThe json_type_double object that is serialized.
pbThe destination buffer.
levelIgnored.
flagsIgnored.
JSON_EXPORT int json_object_equal ( struct json_object *  obj1,
struct json_object *  obj2 
)

Check if two json_object's are equal

If the passed objects are equal 1 will be returned. Equality is defined as follows:

  • json_objects of different types are never equal
  • json_objects of the same primitive type are equal if the c-representation of their value is equal
  • json-arrays are considered equal if all values at the same indices are equal (same order)
  • Complex json_objects are considered equal if all contained objects referenced by their key are equal, regardless their order.
Parameters
obj1the first json_object instance
obj2the second json_object instance
Returns
whether both objects are equal or not
JSON_EXPORT struct json_object* json_object_get ( struct json_object *  obj)
read

Increment the reference count of json_object, thereby taking ownership of it.

Cases where you might need to increase the refcount include:

Parameters
objthe json_object instance
See Also
json_object_put()
json_object_object_get()
json_object_array_get_idx()
JSON_EXPORT struct array_list* json_object_get_array ( const struct json_object *  obj)
read

Get the arraylist of a json_object of type json_type_array

Parameters
objthe json_object instance
Returns
an arraylist
JSON_EXPORT json_bool json_object_get_boolean ( const struct json_object *  obj)

Get the json_bool value of a json_object

The type is coerced to a json_bool if the passed object is not a json_bool. integer and double objects will return 0 if there value is zero or 1 otherwise. If the passed object is a string it will return 1 if it has a non zero length. If any other object type is passed 1 will be returned if the object is not NULL.

Parameters
objthe json_object instance
Returns
a json_bool
JSON_EXPORT double json_object_get_double ( const struct json_object *  obj)

Get the double floating point value of a json_object

The type is coerced to a double if the passed object is not a double. integer objects will return their double conversion. Strings will be parsed as a double. If no conversion exists then 0.0 is returned and errno is set to EINVAL. null is equivalent to 0 (no error values set)

If the value is too big to fit in a double, then the value is set to the closest infinity with errno set to ERANGE. If strings cannot be converted to their double value, then EINVAL is set & NaN is returned.

Arrays of length 0 are interpreted as 0 (with no error flags set). Arrays of length 1 are effectively cast to the equivalent object and converted using the above rules. All other arrays set the error to EINVAL & return NaN.

NOTE: Set errno to 0 directly before a call to this function to determine whether or not conversion was successful (it does not clear the value for you).

Parameters
objthe json_object instance
Returns
a double floating point number
JSON_EXPORT int32_t json_object_get_int ( const struct json_object *  obj)

Get the int value of a json_object

The type is coerced to a int if the passed object is not a int. double objects will return their integer conversion. Strings will be parsed as an integer. If no conversion exists then 0 is returned and errno is set to EINVAL. null is equivalent to 0 (no error values set)

Note that integers are stored internally as 64-bit values. If the value of too big or too small to fit into 32-bit, INT32_MAX or INT32_MIN are returned, respectively.

Parameters
objthe json_object instance
Returns
an int
JSON_EXPORT int64_t json_object_get_int64 ( const struct json_object *  obj)

Get the int value of a json_object

The type is coerced to a int64 if the passed object is not a int64. double objects will return their int64 conversion. Strings will be parsed as an int64. If no conversion exists then 0 is returned.

NOTE: Set errno to 0 directly before a call to this function to determine whether or not conversion was successful (it does not clear the value for you).

Parameters
objthe json_object instance
Returns
an int64
JSON_EXPORT struct lh_table* json_object_get_object ( const struct json_object *  obj)
read

Get the hashtable of a json_object of type json_type_object

Parameters
objthe json_object instance
Returns
a linkhash
JSON_EXPORT const char* json_object_get_string ( struct json_object *  obj)

Get the string value of a json_object

If the passed object is of type json_type_null (i.e. obj == NULL), NULL is returned.

If the passed object of type json_type_string, the string contents are returned.

Otherwise the JSON representation of the object is returned.

The returned string memory is managed by the json_object and will be freed when the reference count of the json_object drops to zero.

Parameters
objthe json_object instance
Returns
a string or NULL
JSON_EXPORT int json_object_get_string_len ( const struct json_object *  obj)

Get the string length of a json_object

If the passed object is not of type json_type_string then zero will be returned.

Parameters
objthe json_object instance
Returns
int
JSON_EXPORT enum json_type json_object_get_type ( const struct json_object *  obj)

Get the type of the json_object. See also json_type_to_name() to turn this into a string suitable, for instance, for logging.

Parameters
objthe json_object instance
Returns
type being one of: json_type_null (i.e. obj == NULL), json_type_boolean, json_type_double, json_type_int, json_type_object, json_type_array, json_type_string
JSON_EXPORT uint64_t json_object_get_uint64 ( const struct json_object *  obj)

Get the uint value of a json_object

The type is coerced to a uint64 if the passed object is not a uint64. double objects will return their uint64 conversion. Strings will be parsed as an uint64. If no conversion exists then 0 is returned.

NOTE: Set errno to 0 directly before a call to this function to determine whether or not conversion was successful (it does not clear the value for you).

Parameters
objthe json_object instance
Returns
an uint64
JSON_EXPORT void* json_object_get_userdata ( json_object *  jso)

Returns the userdata set by json_object_set_userdata() or json_object_set_serializer()

Parameters
jsothe object to return the userdata for
JSON_EXPORT int json_object_int_inc ( struct json_object *  obj,
int64_t  val 
)

Increment a json_type_int object by the given amount, which may be negative.

If the type of obj is not json_type_int then 0 is returned with no further action taken. If the addition would result in a overflow, the object value is set to INT64_MAX. If the addition would result in a underflow, the object value is set to INT64_MIN. Neither overflow nor underflow affect the return value.

Parameters
objthe json_object instance
valthe value to add
Returns
1 if the increment succeded, 0 otherwise
JSON_EXPORT int json_object_is_type ( const struct json_object *  obj,
enum json_type  type 
)

Check if the json_object is of a given type

Parameters
objthe json_object instance
typeone of: json_type_null (i.e. obj == NULL), json_type_boolean, json_type_double, json_type_int, json_type_object, json_type_array, json_type_string
JSON_EXPORT struct json_object* json_object_new_array ( void  )
read

Create a new empty json_object of type json_type_array with 32 slots allocated. If you know the array size you'll need ahead of time, use json_object_new_array_ext() instead.

See Also
json_object_new_array_ext()
json_object_array_shrink()
Returns
a json_object of type json_type_array
JSON_EXPORT struct json_object* json_object_new_array_ext ( int  initial_size)
read

Create a new empty json_object of type json_type_array with the desired number of slots allocated.

See Also
json_object_array_shrink()
Parameters
initial_sizethe number of slots to allocate
Returns
a json_object of type json_type_array
JSON_EXPORT struct json_object* json_object_new_boolean ( json_bool  b)
read

Create a new empty json_object of type json_type_boolean

Parameters
ba json_bool 1 or 0
Returns
a json_object of type json_type_boolean
JSON_EXPORT struct json_object* json_object_new_double ( double  d)
read

Create a new empty json_object of type json_type_double

See Also
json_object_double_to_json_string() for how to set a custom format string.
Parameters
dthe double
Returns
a json_object of type json_type_double
JSON_EXPORT struct json_object* json_object_new_double_s ( double  d,
const char *  ds 
)
read

Create a new json_object of type json_type_double, using the exact serialized representation of the value.

This allows for numbers that would otherwise get displayed inefficiently (e.g. 12.3 => "12.300000000000001") to be serialized with the more convenient form.

Notes:

This is used by json_tokener_parse_ex() to allow for an exact re-serialization of a parsed object.

The userdata field is used to store the string representation, so it can't be used for other data if this function is used.

A roughly equivalent sequence of calls, with the difference being that the serialization function won't be reset by json_object_set_double(), is:

jso = json_object_new_double(d);
json_object_set_serializer(jso, json_object_userdata_to_json_string,
strdup(ds), json_object_free_userdata);
Parameters
dthe numeric value of the double.
dsthe string representation of the double. This will be copied.
JSON_EXPORT struct json_object* json_object_new_int ( int32_t  i)
read

Create a new empty json_object of type json_type_int Note that values are stored as 64-bit values internally. To ensure the full range is maintained, use json_object_new_int64 instead.

Parameters
ithe integer
Returns
a json_object of type json_type_int
JSON_EXPORT struct json_object* json_object_new_int64 ( int64_t  i)
read

Create a new empty json_object of type json_type_int

Parameters
ithe integer
Returns
a json_object of type json_type_int
JSON_EXPORT struct json_object* json_object_new_null ( void  )
read

This method exists only to provide a complementary function along the lines of the other json_object_new_* functions. It always returns NULL, and it is entirely acceptable to simply use NULL directly.

JSON_EXPORT struct json_object* json_object_new_object ( void  )
read

Create a new empty object with a reference count of 1. The caller of this object initially has sole ownership. Remember, when using json_object_object_add or json_object_array_put_idx, ownership will transfer to the object/array. Call json_object_get if you want to maintain shared ownership or also add this object as a child of multiple objects or arrays. Any ownerships you acquired but did not transfer must be released through json_object_put.

Returns
a json_object of type json_type_object
JSON_EXPORT struct json_object* json_object_new_string ( const char *  s)
read

Create a new empty json_object of type json_type_string

A copy of the string is made and the memory is managed by the json_object

Parameters
sthe string
Returns
a json_object of type json_type_string
See Also
json_object_new_string_len()
JSON_EXPORT struct json_object* json_object_new_string_len ( const char *  s,
const int  len 
)
read

Create a new empty json_object of type json_type_string and allocate len characters for the new string.

A copy of the string is made and the memory is managed by the json_object

Parameters
sthe string
lenmax length of the new string
Returns
a json_object of type json_type_string
See Also
json_object_new_string()
JSON_EXPORT struct json_object* json_object_new_uint64 ( uint64_t  i)
read

Create a new empty json_object of type json_type_uint

Parameters
ithe integer
Returns
a json_object of type json_type_uint
JSON_EXPORT int json_object_object_add ( struct json_object *  obj,
const char *  key,
struct json_object *  val 
)

Add an object field to a json_object of type json_type_object

The reference count of val will not be incremented, in effect transferring ownership that object to obj, and thus val will be freed when obj is. (i.e. through json_object_put(obj))

If you want to retain a reference to the added object, independent of the lifetime of obj, you must increment the refcount with json_object_get(val) (and later release it with json_object_put()).

Since ownership transfers to obj, you must make sure that you do in fact have ownership over val. For instance, json_object_new_object() will give you ownership until you transfer it, whereas json_object_object_get() does not.

Any previous object stored under key in obj will have its refcount decremented, and be freed normally if that drops to zero.

Parameters
objthe json_object instance
keythe object field name (a private copy will be duplicated)
vala json_object or NULL member to associate with the given field
Returns
On success, 0 is returned. On error, a negative value is returned.
JSON_EXPORT int json_object_object_add_ex ( struct json_object *  obj,
const char *const  key,
struct json_object *const  val,
const unsigned  opts 
)

Add an object field to a json_object of type json_type_object

The semantics are identical to json_object_object_add, except that an additional flag fields gives you more control over some detail aspects of processing. See the description of JSON_C_OBJECT_ADD_* flags for more details.

Parameters
objthe json_object instance
keythe object field name (a private copy will be duplicated)
vala json_object or NULL member to associate with the given field
optsprocess-modifying options. To specify multiple options, use (OPT1|OPT2)
JSON_EXPORT void json_object_object_del ( struct json_object *  obj,
const char *  key 
)

Delete the given json_object field

The reference count will be decremented for the deleted object. If there are no more owners of the value represented by this key, then the value is freed. Otherwise, the reference to the value will remain in memory.

Parameters
objthe json_object instance
keythe object field name
JSON_EXPORT struct json_object* json_object_object_get ( const struct json_object *  obj,
const char *  key 
)
read

Get the json_object associate with a given object field. Deprecated/discouraged: used json_object_object_get_ex instead.

This returns NULL if the field is found but its value is null, or if the field is not found, or if obj is not a json_type_object. If you need to distinguish between these cases, use json_object_object_get_ex().

No reference counts will be changed. There is no need to manually adjust reference counts through the json_object_put/json_object_get methods unless you need to have the child (value) reference maintain a different lifetime than the owning parent (obj). Ownership of the returned value is retained by obj (do not do json_object_put unless you have done a json_object_get). If you delete the value from obj (json_object_object_del) and wish to access the returned reference afterwards, make sure you have first gotten shared ownership through json_object_get (& don't forget to do a json_object_put or transfer ownership to prevent a memory leak).

Parameters
objthe json_object instance
keythe object field name
Returns
the json_object associated with the given field name
JSON_EXPORT json_bool json_object_object_get_ex ( const struct json_object *  obj,
const char *  key,
struct json_object **  value 
)

Get the json_object associated with a given object field.

This returns true if the key is found, false in all other cases (including if obj isn't a json_type_object).

No reference counts will be changed. There is no need to manually adjust reference counts through the json_object_put/json_object_get methods unless you need to have the child (value) reference maintain a different lifetime than the owning parent (obj). Ownership of value is retained by obj.

Parameters
objthe json_object instance
keythe object field name
valuea pointer where to store a reference to the json_object associated with the given field name.

It is safe to pass a NULL value.

Returns
whether or not the key exists
JSON_EXPORT int json_object_object_length ( const struct json_object *  obj)

Get the size of an object in terms of the number of fields it has.

Parameters
objthe json_object whose length to return
JSON_EXPORT int json_object_put ( struct json_object *  obj)

Decrement the reference count of json_object and free if it reaches zero.

You must have ownership of obj prior to doing this or you will cause an imbalance in the reference count, leading to a classic use-after-free bug. In particular, you normally do not need to call json_object_put() on the json_object returned by json_object_object_get() or json_object_array_get_idx().

Just like after calling free() on a block of memory, you must not use obj after calling json_object_put() on it or any object that it is a member of (unless you know you've called json_object_get(obj) to explicitly increment the refcount).

NULL may be passed, which which case this is a no-op.

Parameters
objthe json_object instance
Returns
1 if the object was freed.

json_object_get()
JSON_EXPORT int json_object_set_boolean ( struct json_object *  obj,
json_bool  new_value 
)

Set the json_bool value of a json_object

The type of obj is checked to be a json_type_boolean and 0 is returned if it is not without any further actions. If type of obj is json_type_boolean the object value is changed to new_value

Parameters
objthe json_object instance
new_valuethe value to be set
Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT int json_object_set_double ( struct json_object *  obj,
double  new_value 
)

Set the double value of a json_object

The type of obj is checked to be a json_type_double and 0 is returned if it is not without any further actions. If type of obj is json_type_double the object value is changed to new_value

If the object was created with json_object_new_double_s(), the serialization function is reset to the default and the cached serialized value is cleared.

Parameters
objthe json_object instance
new_valuethe value to be set
Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT int json_object_set_int ( struct json_object *  obj,
int  new_value 
)

Set the int value of a json_object

The type of obj is checked to be a json_type_int and 0 is returned if it is not without any further actions. If type of obj is json_type_int the object value is changed to new_value

Parameters
objthe json_object instance
new_valuethe value to be set
Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT int json_object_set_int64 ( struct json_object *  obj,
int64_t  new_value 
)

Set the int64_t value of a json_object

The type of obj is checked to be a json_type_int and 0 is returned if it is not without any further actions. If type of obj is json_type_int the object value is changed to new_value

Parameters
objthe json_object instance
new_valuethe value to be set
Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT void json_object_set_serializer ( json_object *  jso,
json_object_to_json_string_fn *  to_string_func,
void *  userdata,
json_object_delete_fn *  user_delete 
)

Set a custom serialization function to be used when this particular object is converted to a string by json_object_to_json_string.

If custom userdata is already set on this object, any existing user_delete function is called before the new one is set.

If to_string_func is NULL the default behaviour is reset (but the userdata and user_delete fields are still set).

The userdata parameter is optional and may be passed as NULL. It can be used to provide additional data for to_string_func to use. This parameter may be NULL even if user_delete is non-NULL.

The user_delete parameter is optional and may be passed as NULL, even if the userdata parameter is non-NULL. It will be called just before the json_object is deleted, after it's reference count goes to zero (see json_object_put()). If this is not provided, it is up to the caller to free the userdata at an appropriate time. (i.e. after the json_object is deleted)

Note that the userdata is the same as set by json_object_set_userdata(), so care must be taken not to overwrite the value when both a custom serializer and json_object_set_userdata() are used.

Parameters
jsothe object to customize
to_string_functhe custom serialization function
userdataan optional opaque cookie
user_deletean optional function from freeing userdata
JSON_EXPORT int json_object_set_string ( json_object *  obj,
const char *  new_value 
)

Set the string value of a json_object with zero terminated strings equivalent to json_object_set_string_len (obj, new_value, strlen(new_value))

Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT int json_object_set_string_len ( json_object *  obj,
const char *  new_value,
int  len 
)

Set the string value of a json_object str

The type of obj is checked to be a json_type_string and 0 is returned if it is not without any further actions. If type of obj is json_type_string the object value is changed to new_value

Parameters
objthe json_object instance
new_valuethe value to be set; Since string length is given in len this need not be zero terminated
lenthe length of new_value
Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT int json_object_set_uint64 ( struct json_object *  obj,
uint64_t  new_value 
)

Set the uint64_t value of a json_object

The type of obj is checked to be a json_type_uint and 0 is returned if it is not without any further actions. If type of obj is json_type_uint the object value is changed to new_value

Parameters
objthe json_object instance
new_valuethe value to be set
Returns
1 if value is set correctly, 0 otherwise
JSON_EXPORT void json_object_set_userdata ( json_object *  jso,
void *  userdata,
json_object_delete_fn *  user_delete 
)

Set an opaque userdata value for an object

The userdata can be retrieved using json_object_get_userdata().

If custom userdata is already set on this object, any existing user_delete function is called before the new one is set.

The user_delete parameter is optional and may be passed as NULL, even if the userdata parameter is non-NULL. It will be called just before the json_object is deleted, after it's reference count goes to zero (see json_object_put()). If this is not provided, it is up to the caller to free the userdata at an appropriate time. (i.e. after the json_object is deleted)

Note: Objects created by parsing strings may have custom serializers set which expect the userdata to contain specific data (due to use of json_object_new_double_s()). In this case, json_object_set_serialiser() with NULL as to_string_func should be used instead to set the userdata and reset the serializer to its default value.

Parameters
jsothe object to set the userdata for
userdataan optional opaque cookie
user_deletean optional function from freeing userdata
JSON_EXPORT const char* json_object_to_json_string ( struct json_object *  obj)

Stringify object to json format. Equivalent to json_object_to_json_string_ext(obj, JSON_C_TO_STRING_SPACED) The pointer you get is an internal of your json object. You don't have to free it, later use of json_object_put() should be sufficient. If you can not ensure there's no concurrent access to *obj use strdup().

Parameters
objthe json_object instance
Returns
a string in JSON format
JSON_EXPORT const char* json_object_to_json_string_ext ( struct json_object *  obj,
int  flags 
)

Stringify object to json format

See Also
json_object_to_json_string() for details on how to free string.
Parameters
objthe json_object instance
flagsformatting options, see JSON_C_TO_STRING_PRETTY and other constants
Returns
a string in JSON format
JSON_EXPORT const char* json_object_to_json_string_length ( struct json_object *  obj,
int  flags,
size_t *  length 
)

Stringify object to json format

See Also
json_object_to_json_string() for details on how to free string.
Parameters
objthe json_object instance
flagsformatting options, see JSON_C_TO_STRING_PRETTY and other constants
lengtha pointer where, if not NULL, the length (without null) is stored
Returns
a string in JSON format and the length if not NULL

Variable Documentation

JSON_EXPORT json_c_shallow_copy_fn json_c_shallow_copy_default

The default shallow copy implementation for use with json_object_deep_copy(). This simply calls the appropriate json_object_new_<type>() function and copies over the serializer function (_to_json_string internal field of the json_object structure) but not any _userdata or _user_delete values.

If you're writing a custom shallow_copy function, perhaps because you're using your own custom serializer, you can call this first to create the new object before customizing it with json_object_set_serializer().

Returns
1 on success, -1 on errors, but never 2.
JSON_EXPORT json_object_delete_fn json_object_free_userdata

Simply call free on the userdata pointer. Can be used with json_object_set_serializer().

Parameters
jsounused
userdatathe pointer that is passed to free().
JSON_EXPORT json_object_to_json_string_fn json_object_userdata_to_json_string

Copy the jso->_userdata string over to pb as-is. Can be used with json_object_set_serializer().

Parameters
jsoThe object whose _userdata is used.
pbThe destination buffer.

Function Documentation

JSON_EXPORT struct json_object_iterator json_object_iter_begin ( struct json_object *  obj)
read

Retrieves an iterator to the first pair of the JSON Object.

Warning
Any modification of the underlying pair invalidates all iterators to that pair.
Parameters
objJSON Object instance (MUST be of type json_object)
Returns
json_object_iterator If the JSON Object has at least one pair, on return, the iterator refers to the first pair. If the JSON Object doesn't have any pairs, the returned iterator is equivalent to the "end" iterator for the same JSON Object instance.
struct json_object_iterator it;
struct json_object_iterator itEnd;

obj = json_tokener_parse("{'first':'george', 'age':100}");
it = json_object_iter_begin(obj);
itEnd = json_object_iter_end(obj);

}
JSON_EXPORT struct json_object_iterator json_object_iter_end ( const struct json_object *  obj)
read

Retrieves the iterator that represents the position beyond the last pair of the given JSON Object instance.

Warning
Do NOT write code that assumes that the "end" iterator value is NULL, even if it is so in a particular instance of the implementation.
Note
The reason we do not (and MUST NOT) provide "json_object_iter_is_end(json_object_iterator* iter)" type of API is because it would limit the underlying representation of name/value containment (or force us to add additional, otherwise unnecessary, fields to the iterator structure). The "end" iterator and the equality test method, on the other hand, permit us to cleanly abstract pretty much any reasonable underlying representation without burdening the iterator structure with unnecessary data.
For performance reasons, memorize the "end" iterator prior to any loop.
Parameters
objJSON Object instance (MUST be of type json_object)
Returns
json_object_iterator On return, the iterator refers to the "end" of the Object instance's pairs (i.e., NOT the last pair, but "beyond the last pair" value)
JSON_EXPORT json_bool json_object_iter_equal ( const struct json_object_iterator *  iter1,
const struct json_object_iterator *  iter2 
)

Tests two iterators for equality. Typically used to test for end of iteration by comparing an iterator to the corresponding "end" iterator (that was derived from the same JSON Object instance).

Note
The reason we do not (and MUST NOT) provide "json_object_iter_is_end(json_object_iterator* iter)" type of API is because it would limit the underlying representation of name/value containment (or force us to add additional, otherwise unnecessary, fields to the iterator structure). The equality test method, on the other hand, permits us to cleanly abstract pretty much any reasonable underlying representation.
Parameters
iter1Pointer to first valid, non-NULL iterator
iter2POinter to second valid, non-NULL iterator
Warning
if a NULL iterator pointer or an uninitialized or invalid iterator, or iterators derived from different JSON Object instances are passed, bad things will happen!
Returns
json_bool non-zero if iterators are equal (i.e., both reference the same name/value pair or are both at "end"); zero if they are not equal.
JSON_EXPORT struct json_object_iterator json_object_iter_init_default ( void  )
read

Initializes an iterator structure to a "default" value that is convenient for initializing an iterator variable to a default state (e.g., initialization list in a class' constructor).

struct json_object_iterator iter = json_object_iter_init_default();
MyClass() : iter_(json_object_iter_init_default())
Note
The initialized value doesn't reference any specific pair, is considered an invalid iterator, and MUST NOT be passed to any json-c API that expects a valid iterator.
User and internal code MUST NOT make any assumptions about and dependencies on the value of the "default" iterator value.
Returns
json_object_iterator
JSON_EXPORT void json_object_iter_next ( struct json_object_iterator *  iter)

Returns an iterator to the next pair, if any

Warning
Any modification of the underlying pair invalidates all iterators to that pair.
Parameters
iter[IN/OUT] Pointer to iterator that references a name/value pair; MUST be a valid, non-end iterator. WARNING: bad things will happen if invalid or "end" iterator is passed. Upon return will contain the reference to the next pair if there is one; if there are no more pairs, will contain the "end" iterator value, which may be compared against the return value of json_object_iter_end() for the same JSON Object instance.
JSON_EXPORT const char* json_object_iter_peek_name ( const struct json_object_iterator *  iter)

Returns a const pointer to the name of the pair referenced by the given iterator.

Parameters
iterpointer to iterator that references a name/value pair; MUST be a valid, non-end iterator.
Warning
bad things will happen if an invalid or "end" iterator is passed.
Returns
const char* Pointer to the name of the referenced name/value pair. The name memory belongs to the name/value pair, will be freed when the pair is deleted or modified, and MUST NOT be modified or freed by the user.
JSON_EXPORT struct json_object* json_object_iter_peek_value ( const struct json_object_iterator *  iter)
read

Returns a pointer to the json-c instance representing the value of the referenced name/value pair, without altering the instance's reference count.

Parameters
iterpointer to iterator that references a name/value pair; MUST be a valid, non-end iterator.
Warning
bad things will happen if invalid or "end" iterator is passed.
Returns
struct json_object* Pointer to the json-c value instance of the referenced name/value pair; the value's reference count is not changed by this function: if you plan to hold on to this json-c node, take a look at json_object_get() and json_object_put(). IMPORTANT: json-c API represents the JSON Null value as a NULL json_object instance pointer.

Detailed Description

JSON Pointer (RFC 6901) implementation for retrieving objects from a json-c object tree.

Function Documentation

JSON_EXPORT int json_pointer_get ( struct json_object *  obj,
const char *  path,
struct json_object **  res 
)

Retrieves a JSON sub-object from inside another JSON object using the JSON pointer notation as defined in RFC 6901 https://tools.ietf.org/html/rfc6901

The returned JSON sub-object is equivalent to parsing manually the 'obj' JSON tree ; i.e. it's not a new object that is created, but rather a pointer inside the JSON tree.

Internally, this is equivalent to doing a series of 'json_object_object_get()' and 'json_object_array_get_idx()' along the given 'path'.

Note that the 'path' string supports 'printf()' type arguments, so, whatever is added after the 'res' param will be treated as an argument for 'path' Example: json_pointer_get(obj, "/foo/%d/%s", &res, 0, bar) This means, that you need to escape '' with '%' (just like in printf())

Parameters
objthe json_object instance/tree from where to retrieve sub-objects
patha (RFC6901) string notation for the sub-object to retrieve
resa pointer that stores a reference to the json_object associated with the given path
Returns
negative if an error (or not found), or 0 if succeeded
JSON_EXPORT int json_pointer_getf ( struct json_object *  obj,
struct json_object **  res,
const char *  path_fmt,
  ... 
)

This is a variant of 'json_pointer_get()' that supports printf() style arguments.

Example: json_pointer_getf(obj, res, "/foo/%d/%s", 0, bak) This also means that you need to escape '' with '%' (just like in printf())

Please take into consideration all recommended 'printf()' format security aspects when using this function.

Parameters
objthe json_object instance/tree to which to add a sub-object
resa pointer that stores a reference to the json_object associated with the given path
path_fmta printf() style format for the path
Returns
negative if an error (or not found), or 0 if succeeded
JSON_EXPORT int json_pointer_set ( struct json_object **  obj,
const char *  path,
struct json_object *  value 
)

Sets JSON object 'value' in the 'obj' tree at the location specified by the 'path'. 'path' is JSON pointer notation as defined in RFC 6901 https://tools.ietf.org/html/rfc6901

Note that 'obj' is a double pointer, mostly for the "" (empty string) case, where the entire JSON object would be replaced by 'value'. In the case of the "" path, the object at '*obj' will have it's refcount decremented with 'json_object_put()' and the 'value' object will be assigned to it.

For other cases (JSON sub-objects) ownership of 'value' will be transferred into '*obj' via 'json_object_object_add()' & 'json_object_array_put_idx()', so the only time the refcount should be decremented for 'value' is when the return value of 'json_pointer_set()' is negative (meaning the 'value' object did not get set into '*obj').

That also implies that 'json_pointer_set()' does not do any refcount incrementing. (Just that single decrement that was mentioned above).

Note that the 'path' string supports 'printf()' type arguments, so, whatever is added after the 'value' param will be treated as an argument for 'path' Example: json_pointer_set(obj, "/foo/%d/%s", value, 0, bak) This means, that you need to escape '' with '%' (just like in printf())

Parameters
objthe json_object instance/tree to which to add a sub-object
patha (RFC6901) string notation for the sub-object to set in the tree
valueobject to set at path
Returns
negative if an error (or not found), or 0 if succeeded
JSON_EXPORT int json_pointer_setf ( struct json_object **  obj,
struct json_object *  value,
const char *  path_fmt,
  ... 
)

This is a variant of 'json_pointer_set()' that supports printf() style arguments.

Example: json_pointer_setf(obj, value, "/foo/%d/%s", 0, bak) This also means that you need to escape '' with '%' (just like in printf())

Please take into consideration all recommended 'printf()' format security aspects when using this function.

Parameters
objthe json_object instance/tree to which to add a sub-object
valueobject to set at path
path_fmta printf() style format for the path
Returns
negative if an error (or not found), or 0 if succeeded

Detailed Description

Methods to parse an input string into a tree of json_object objects.

Macro Definition Documentation

#define JSON_TOKENER_ALLOW_TRAILING_CHARS   0x02

Use with JSON_TOKENER_STRICT to allow trailing characters after the first parsed object.

See Also
json_tokener_set_flags()
#define JSON_TOKENER_DEFAULT_DEPTH   32
#define JSON_TOKENER_STRICT   0x01

Be strict when parsing JSON input. Use caution with this flag as what is considered valid may become more restrictive from one release to the next, causing your code to fail on previously working input.

Note that setting this will also effectively disable parsing of multiple json objects in a single character stream (e.g. {"foo":123}{"bar":234}); if you want to allow that also set JSON_TOKENER_ALLOW_TRAILING_CHARS

This flag is not set by default.

See Also
json_tokener_set_flags()
#define JSON_TOKENER_VALIDATE_UTF8   0x10

Cause json_tokener_parse_ex() to validate that input is UTF8. If this flag is specified and validation fails, then json_tokener_get_error(tok) will return json_tokener_error_parse_utf8_string

This flag is not set by default.

Function Documentation

JSON_EXPORT const char* json_tokener_error_desc ( enum json_tokener_error  jerr)

Given an error previously returned by json_tokener_get_error(), return a human readable description of the error.

Returns
a generic error message is returned if an invalid error value is provided.
JSON_EXPORT void json_tokener_free ( struct json_tokener *  tok)

Free a json_tokener previously allocated with json_tokener_new().

JSON_EXPORT enum json_tokener_error json_tokener_get_error ( struct json_tokener *  tok)

Retrieve the error caused by the last call to json_tokener_parse_ex(), or json_tokener_success if there is no error.

When parsing a JSON string in pieces, if the tokener is in the middle of parsing this will return json_tokener_continue.

See Also
json_tokener_error_desc().
JSON_EXPORT size_t json_tokener_get_parse_end ( struct json_tokener *  tok)

Return the offset of the byte after the last byte parsed relative to the start of the most recent string passed in to json_tokener_parse_ex(). i.e. this is where parsing would start again if the input contains another JSON object after the currently parsed one.

Note that when multiple parse calls are issued, this is not the total number of characters parsed.

In the past this would have been accessed as tok->char_offset.

See json_tokener_parse_ex() for an example of how to use this.

JSON_EXPORT struct json_tokener* json_tokener_new ( void  )
read

Allocate a new json_tokener. When done using that to parse objects, free it with json_tokener_free(). See json_tokener_parse_ex() for usage details.

JSON_EXPORT struct json_tokener* json_tokener_new_ex ( int  depth)
read

Allocate a new json_tokener with a custom max nesting depth.

See Also
JSON_TOKENER_DEFAULT_DEPTH
JSON_EXPORT struct json_object* json_tokener_parse ( const char *  str)
read

Parse a json_object out of the string str.

If you need more control over how the parsing occurs, see json_tokener_parse_ex().

JSON_EXPORT struct json_object* json_tokener_parse_ex ( struct json_tokener *  tok,
const char *  str,
int  len 
)
read

Parse a string and return a non-NULL json_object if a valid JSON value is found. The string does not need to be a JSON object or array; it can also be a string, number or boolean value.

A partial JSON string can be parsed. If the parsing is incomplete, NULL will be returned and json_tokener_get_error() will return json_tokener_continue. json_tokener_parse_ex() can then be called with additional bytes in str to continue the parsing.

If json_tokener_parse_ex() returns NULL and the error is anything other than json_tokener_continue, a fatal error has occurred and parsing must be halted. Then, the tok object must not be reused until json_tokener_reset() is called.

When a valid JSON value is parsed, a non-NULL json_object will be returned, with a reference count of one which belongs to the caller. Also, json_tokener_get_error() will return json_tokener_success. Be sure to check the type with json_object_is_type() or json_object_get_type() before using the object.

Trailing characters after the parsed value do not automatically cause an error. It is up to the caller to decide whether to treat this as an error or to handle the additional characters, perhaps by parsing another json value starting from that point.

If the caller knows that they are at the end of their input, the length passed MUST include the final '\0' character, so values with no inherent end (i.e. numbers) can be properly parsed, rather than just returning json_tokener_continue.

Extra characters can be detected by comparing the value returned by json_tokener_get_parse_end() against the length of the last len parameter passed in.

The tokener does not maintain an internal buffer so the caller is responsible for a subsequent call to json_tokener_parse_ex with an appropriate str parameter starting with the extra characters.

This interface is presently not 64-bit clean due to the int len argument so the function limits the maximum string size to INT32_MAX (2GB). If the function is called with len == -1 then strlen is called to check the string length is less than INT32_MAX (2GB)

Example:

json_object *jobj = NULL;
const char *mystring = NULL;
int stringlen = 0;
enum json_tokener_error jerr;
do {
mystring = ... // get JSON string, e.g. read from file, etc...
stringlen = strlen(mystring);
if (end_of_input)
stringlen++; // Include the '\0' if we know we're at the end of input
jobj = json_tokener_parse_ex(tok, mystring, stringlen);
} while ((jerr = json_tokener_get_error(tok)) == json_tokener_continue);
if (jerr != json_tokener_success)
{
fprintf(stderr, "Error: %s\n", json_tokener_error_desc(jerr));
// Handle errors, as appropriate for your application.
}
if (json_tokener_get_parse_end(tok) < stringlen)
{
// Handle extra characters after parsed object as desired.
// e.g. issue an error, parse another object from that point, etc...
}
// Success, use jobj here.
Parameters
toka json_tokener previously allocated with json_tokener_new()
stran string with any valid JSON expression, or portion of. This does not need to be null terminated.
lenthe length of str
JSON_EXPORT struct json_object* json_tokener_parse_verbose ( const char *  str,
enum json_tokener_error *  error 
)
read

Parser a json_object out of the string str, but if it fails return the error in *error.

See Also
json_tokener_parse()
json_tokener_parse_ex()
JSON_EXPORT void json_tokener_reset ( struct json_tokener *  tok)

Reset the state of a json_tokener, to prepare to parse a brand new JSON object.

JSON_EXPORT void json_tokener_set_flags ( struct json_tokener *  tok,
int  flags 
)

Set flags that control how parsing will be done.

Function Documentation

JSON_EXPORT struct json_object* json_object_from_fd ( int  fd)
read

Create a JSON object from an already opened file descriptor, using the default maximum object depth. (JSON_TOKENER_DEFAULT_DEPTH)

See json_object_from_fd_ex() for details.

JSON_EXPORT struct json_object* json_object_from_fd_ex ( int  fd,
int  depth 
)
read

Create a JSON object from already opened file descriptor.

This function can be helpful, when you opened the file already, e.g. when you have a temp file. Note, that the fd must be readable at the actual position, i.e. use lseek(fd, 0, SEEK_SET) before.

The depth argument specifies the maximum object depth to pass to json_tokener_new_ex(). When depth == -1, JSON_TOKENER_DEFAULT_DEPTH is used instead.

Returns NULL on failure. See json_util_get_last_err() for details.

JSON_EXPORT struct json_object* json_object_from_file ( const char *  filename)
read

Read the full contents of the given file, then convert it to a json_object using json_tokener_parse().

Returns NULL on failure. See json_util_get_last_err() for details.

JSON_EXPORT int json_object_to_fd ( int  fd,
struct json_object *  obj,
int  flags 
)

Convert the json_object to a string and write it to the file descriptor. Handles partial writes and will keep writing until done, or an error occurs.

Parameters
fdan open, writable file descriptor to write to
objthe object to serializer and write
flagsflags to pass to json_object_to_json_string_ext()
Returns
-1 if something fails. See json_util_get_last_err() for details.
JSON_EXPORT int json_object_to_file ( const char *  filename,
struct json_object *  obj 
)

Equivalent to: json_object_to_file_ext(filename, obj, JSON_C_TO_STRING_PLAIN);

Returns -1 if something fails. See json_util_get_last_err() for details.

JSON_EXPORT int json_object_to_file_ext ( const char *  filename,
struct json_object *  obj,
int  flags 
)

Open and truncate the given file, creating it if necessary, then convert the json_object to a string and write it to the file.

Returns -1 if something fails. See json_util_get_last_err() for details.

JSON_EXPORT int json_parse_double ( const char *  buf,

Macro Definition Documentation

#define JSON_C_VISIT_RETURN_CONTINUE   0

This json_c_visit_userfunc return value indicates that iteration should proceed normally.

#define JSON_C_VISIT_RETURN_ERROR   -1

This json_c_visit_userfunc return value indicates that iteration should stop immediately, and cause json_c_visit to return an error.

#define JSON_C_VISIT_RETURN_POP   767

This json_c_visit_userfunc return value indicates that iteration of the fields/elements of the containing object should stop and continue "popped up" a level of the object hierarchy. For example, returning this when handling arg will result in arg3 and any other fields being skipped. The next call to userfunc will be the JSON_C_VISIT_SECOND call on "foo", followed by a userfunc call on "bar". 

{
  "foo": {
    "arg1": 1,
    "arg2": 2,
    "arg3": 3,
    ...
  },
  "bar": {
    ...
  }
}
#define JSON_C_VISIT_RETURN_SKIP   7547

This json_c_visit_userfunc return value indicates that iteration over the members of the current object should be skipped. If the current object isn't a container (array or object), this is no different than JSON_C_VISIT_RETURN_CONTINUE.

#define JSON_C_VISIT_RETURN_STOP   7867

This json_c_visit_userfunc return value indicates that iteration should stop immediately, and cause json_c_visit to return success.

#define JSON_C_VISIT_SECOND   0x02

Passed to json_c_visit_userfunc as one of the flags values to indicate that this is the second time a container (array or object) is being called, after all of it's members have been iterated over.

Typedef Documentation

typedef int( json_c_visit_userfunc)(json_object *jso, int flags, json_object *parent_jso, const char *jso_key, size_t *jso_index, void *userarg)

Function Documentation

JSON_EXPORT int json_c_visit ( json_object *  jso,
int  future_flags,
json_c_visit_userfunc *  userfunc,
void *  userarg 
)

Visit each object in the JSON hierarchy starting at jso. For each object, userfunc is called, passing the object and userarg. If the object has a parent (i.e. anything other than jso itself) its parent will be passed as parent_jso, and either jso_key or jso_index will be set, depending on whether the parent is an object or an array.

Nodes will be visited depth first, but containers (arrays and objects) will be visited twice, the second time with JSON_C_VISIT_SECOND set in flags.

userfunc must return one of the defined return values, to indicate whether and how to continue visiting nodes, or one of various ways to stop.

Returns 0 if nodes were visited successfully, even if some were intentionally skipped due to what userfunc returned. Returns <0 if an error occurred during iteration, including if userfunc returned JSON_C_VISIT_RETURN_ERROR.

int lh_table_delete ( struct lh_table *  t,
const void *  k 
)

Delete a record from the table.

If a callback free function is provided then it is called for the for the item being deleted.

Parameters
tthe table to delete from.
ka pointer to the key to delete.
Returns
0 if the item was deleted.
-1 if it was not found.
int lh_table_delete_entry ( struct lh_table *  t,

void lh_table_free ( struct lh_table *  t)

Free a linkhash table.

If a lh_entry_free_fn callback free function was provided then it is called for all entries in the table.

Parameters
ttable to free.
int lh_table_insert ( struct lh_table *  t,
const void *  k,
const void *  v 
)

Insert a record into the table.

Detailed Description

Internal string buffer handing. Unless you're writing a json_object_to_json_string_fn implementation for use with json_object_set_serializer() direct use of this is not recommended.

Macro Definition Documentation

#define JSON_EXPORT   extern
#define printbuf_length (   p)    ((p)->bpos)
#define printbuf_memappend_fast (   p,
  bufptr,
  bufsize 
)
Value:
do \
{ \
if ((p->size - p->bpos) > bufsize) \
{ \
memcpy(p->buf + p->bpos, (bufptr), bufsize); \
p->bpos += bufsize; \
p->buf[p->bpos] = '\0'; \
} \
else \
{ \
printbuf_memappend(p, (bufptr), bufsize); \
} \
} while (0)
#define printbuf_strappend (   pb,
  str 
)    printbuf_memappend((pb), _printbuf_check_literal(str), sizeof(str) - 1)

This is an optimization wrapper around printbuf_memappend() that is useful for appending string literals. Since the size of string constants is known at compile time, using this macro can avoid a costly strlen() call. This is especially helpful when a constant string must be appended many times. If you got here because of a compilation error caused by passing something other than a string literal, use printbuf_memappend_fast() in conjunction with strlen().

Typedef Documentation

typedef struct printbuf printbuf

Function Documentation

JSON_EXPORT void printbuf_free ( struct printbuf *  p)
JSON_EXPORT int printbuf_memappend ( struct printbuf *  p,
const char *  buf,
int  size 
)
JSON_EXPORT int printbuf_memset ( struct printbuf *  pb,
int  offset,
int  charvalue,
int  len 
)

Set len bytes of the buffer to charvalue, starting at offset offset. Similar to calling memset(x, charvalue, len);

The memory allocated for the buffer is extended as necessary.

If offset is -1, this starts at the end of the current data in the buffer.

JSON_EXPORT struct printbuf* printbuf_new ( void  )
read
JSON_EXPORT void printbuf_reset ( struct printbuf *  p)
JSON_EXPORT int sprintbuf ( struct printbuf *  p,
const char *  msg,
  ... 
)

Formatted print to printbuf.

This function is the most expensive of the available functions for appending string data to a printbuf and should be used only where convenience is more important than speed. Avoid using this function in high performance code or tight loops; in these scenarios, consider using snprintf() with a static buffer in conjunction with one of the printbuf_*append() functions.

These are functions for producing 32-bit hashes for hash table lookup. hashword(), hashlittle(), hashlittle2(), hashbig(), mix(), and final() are externally useful functions. Routines to test the hash are included if SELF_TEST is defined. You can use this free for any purpose. It's in the public domain. It has no warranty. You probably want to use hashlittle(). hashlittle() and hashbig() hash byte arrays. hashlittle() is is faster than hashbig() on little-endian machines. Intel and AMD are little-endian machines. On second thought, you probably want hashlittle2(), which is identical to hashlittle() except it returns two 32-bit hashes for the price of one. You could implement hashbig2() if you wanted but I haven't bothered here. If you want to find a hash of, say, exactly 7 integers, do a = i1; b = i2; c = i3; mix(a,b,c); a += i4; b += i5; c += i6; mix(a,b,c); a += i7; final(a,b,c); then use c as the hash value. If you have a variable length array of 4-byte integers to hash, use hashword(). If you have a byte array (like a character string), use hashlittle(). If you have several byte arrays, or a mix of things, see the comments above hashlittle(). Why is this so big? I read 12 bytes at a time into 3 4-byte integers, then mix those integers. This is fast (you can do a lot more thorough mixing with 12*3 instructions on 3 integers than you can with 3 instructions on 1 byte), but shoehorning those bytes into integers efficiently is messy. ------------------------------------------------------------------------------- */ /* * My best guess at if you are big-endian or little-endian.

This is reversible, so any information in (a,b,c) before mix() is still in (a,b,c) after mix().

I used http://burtleburtle.net/bob/hash/avalanche.html to choose the operations, constants, and arrangements of the variables. This does not achieve avalanche. There are input bits of (a,b,c) that fail to affect some output bits of (a,b,c), especially of a. The most thoroughly mixed value is c, but it doesn't really even achieve avalanche in c. This allows some parallelism. Read-after-writes are good at doubling the number of bits affected, so the goal of mixing pulls in the opposite direction as the goal of parallelism. I did what I could. Rotates seem to cost as much as shifts on every machine I could lay my hands on, and rotates are much kinder to the top and bottom bits, so I used rotates. ------------------------------------------------------------------------------- */ /* clang-format off */ #define mix(a,b,c) \ { \ a -= c; a ^= rot(c, 4); c += b; \ b -= a; b ^= rot(a, 6); a += c; \ c -= b; c ^= rot(b, 8); b += a; \ a -= c; a ^= rot(c,16); c += b; \ b -= a; b ^= rot(a,19); a += c; \ c -= b; c ^= rot(b, 4); b += a; \ } /* clang-format on */ /* ------------------------------------------------------------------------------- final -- final mixing of 3 32-bit values (a,b,c) into c Pairs of (a,b,c) values differing in only a few bits will usually produce values of c that look totally different.
