jansson 2.1

With this flag enabled, the decoder stops after a valid JSON input and
thus allows extra data after it.

Fixes GH-25.

+Version 2.1 (in development)
+============================
+
+* New features:
+
+  - `json_loadb()`: Decode a string with a given size, useful if the
+    string is not null terminated.
+
+  - Add ``JSON_ENCODE_ANY`` encoding flag to allow encoding any JSON
+    value. By default, only arrays and objects can be encoded. (#19)
+
+  - Add ``JSON_REJECT_DUPLICATES`` decoding flag to issue a decoding
+    error if any JSON object in the input contins duplicate keys. (#3)
+
+  - Add ``JSON_DISABLE_EOF_CHECK`` decoding flag to stop decoding after a
+    valid JSON input. This allows other data after the JSON data.
+
+* Bug fixes:
+
+  - Fix an additional memory leak when memory allocation fails in
+    `json_object_set()` and friends.
+
+  - Clear errno before calling `strtod()` for better portability. (#27)
+
+* Building:
+
+  - Avoid set-but-not-used warning/error in a test. (#20)
+
+* Other:
+
+  - Minor clarifications to documentation.
+
+
+Version 2.0.1
+=============
+
+Released 2011-03-31
+
+* Bug fixes:
+
+  - Replace a few `malloc()` and `free()` calls with their
+    counterparts that support custom memory management.
+
+  - Fix object key hashing in json_unpack() strict checking mode.
+
+  - Fix the parentheses in ``JANSSON_VERSION_HEX`` macro.
+
+  - Fix `json_object_size()` return value.
+
+  - Fix a few compilation issues.
+
+* Portability:
+
+  - Enhance portability of `va_copy()`.
+
+  - Test framework portability enhancements.
+
+* Documentation:
+
+  - Distribute ``doc/upgrading.rst`` with the source tarball.
+
+  - Build documentation in strict mode in ``make distcheck``.
+
+
+Version 2.0
+===========
+
+Released 2011-02-28
+
+This release is backwards incompatible with the 1.x release series.
+See the chapter "Upgrading from older versions" in documentation for
+details.
+
+* Backwards incompatible changes:
+
+  - Unify unsigned integer usage in the API: All occurences of
+    unsigned int and unsigned long have been replaced with size_t.
+
+  - Change JSON integer's underlying type to the widest signed integer
+    type available, i.e. long long if it's supported, otherwise long.
+    Add a typedef json_int_t that defines the type.
+
+  - Change the maximum indentation depth to 31 spaces in encoder. This
+    frees up bits from the flags parameter of encoding functions
+    `json_dumpf()`, `json_dumps()` and `json_dump_file()`.
+
+  - For future needs, add a flags parameter to all decoding functions
+    `json_loadf()`, `json_loads()` and `json_load_file()`.
+
+* New features
+
+  - `json_pack()`, `json_pack_ex()`, `json_vpack_ex()`: Create JSON
+    values based on a format string.
+
+  - `json_unpack()`, `json_unpack_ex()`, `json_vunpack_ex()`: Simple
+    value extraction and validation functionality based on a format
+    string.
+
+  - Add column, position and source fields to the ``json_error_t``
+    struct.
+
+  - Enhance error reporting in the decoder.
+
+  - ``JANSSON_VERSION`` et al.: Preprocessor constants that define the
+    library version.
+
+  - `json_set_alloc_funcs()`: Set custom memory allocation functions.
+
+* Fix many portability issues, especially on Windows.
+
+* Configuration
+
+  - Add file ``jansson_config.h`` that contains site specific
+    configuration. It's created automatically by the configure script,
+    or can be created by hand if the configure script cannot be used.
+    The file ``jansson_config.h.win32`` can be used without
+    modifications on Windows systems.
+
+  - Add a section to documentation describing how to build Jansson on
+    Windows.
+
+  - Documentation now requires Sphinx 1.0 or newer.
+
+
+Version 1.3
+===========
+
+Released 2010-06-13
+
+* New functions:
+
+  - `json_object_iter_set()`, `json_object_iter_set_new()`: Change
+    object contents while iterating over it.
+
+  - `json_object_iter_at()`: Return an iterator that points to a
+    specific object item.
+
+* New encoding flags:
+
+  - ``JSON_PRESERVE_ORDER``: Preserve the insertion order of object
+    keys.
+
+* Bug fixes:
+
+  - Fix an error that occured when an array or object was first
+    encoded as empty, then populated with some data, and then
+    re-encoded
+
+  - Fix the situation like above, but when the first encoding resulted
+    in an error
+
+* Documentation:
+
+  - Clarify the documentation on reference stealing, providing an
+    example usage pattern
+
+
+Version 1.2.1
+=============
+
+Released 2010-04-03
+
+* Bug fixes:
+
+  - Fix reference counting on ``true``, ``false`` and ``null``
+  - Estimate real number underflows in decoder with 0.0 instead of
+    issuing an error
+
+* Portability:
+
+  - Make ``int32_t`` available on all systems
+  - Support compilers that don't have the ``inline`` keyword
+  - Require Autoconf 2.60 (for ``int32_t``)
+
+* Tests:
+
+  - Print test names correctly when ``VERBOSE=1``
+  - ``test/suites/api``: Fail when a test fails
+  - Enhance tests for iterators
+  - Enhance tests for decoding texts that contain null bytes
+
+* Documentation:
+
+  - Don't remove ``changes.rst`` in ``make clean``
+  - Add a chapter on RFC conformance
+
+
+Version 1.2
+===========
+
+Released 2010-01-21
+
+* New functions:
+
+  - `json_equal()`: Test whether two JSON values are equal
+  - `json_copy()` and `json_deep_copy()`: Make shallow and deep copies
+    of JSON values
+  - Add a version of all functions taking a string argument that
+    doesn't check for valid UTF-8: `json_string_nocheck()`,
+    `json_string_set_nocheck()`, `json_object_set_nocheck()`,
+    `json_object_set_new_nocheck()`
+
+* New encoding flags:
+
+  - ``JSON_SORT_KEYS``: Sort objects by key
+  - ``JSON_ENSURE_ASCII``: Escape all non-ASCII Unicode characters
+  - ``JSON_COMPACT``: Use a compact representation with all unneeded
+    whitespace stripped
+
+* Bug fixes:
+
+  - Revise and unify whitespace usage in encoder: Add spaces between
+    array and object items, never append newline to output.
+  - Remove const qualifier from the ``json_t`` parameter in
+    `json_string_set()`, `json_integer_set()` and `json_real_set`.
+  - Use ``int32_t`` internally for representing Unicode code points
+    (int is not enough on all platforms)
+
+* Other changes:
+
+  - Convert ``CHANGES`` (this file) to reStructured text and add it to
+    HTML documentation
+  - The test system has been refactored. Python is no longer required
+    to run the tests.
+  - Documentation can now be built by invoking ``make html``
+  - Support for pkg-config
+

+
+***************
+RFC Conformance
+***************
+
+JSON is specified in :rfc:`4627`, *"The application/json Media Type
+for JavaScript Object Notation (JSON)"*. This chapter discusses
+Jansson's conformance to this specification.
+
+Character Encoding
+==================
+
+Jansson only supports UTF-8 encoded JSON texts. It does not support or
+auto-detect any of the other encodings mentioned in the RFC, namely
+UTF-16LE, UTF-16BE, UTF-32LE or UTF-32BE. Pure ASCII is supported, as
+it's a subset of UTF-8.
+
+Strings
+=======
+
+JSON strings are mapped to C-style null-terminated character arrays,
+and UTF-8 encoding is used internally. Strings may not contain
+embedded null characters, not even escaped ones.
+
+For example, trying to decode the following JSON text leads to a parse
+error::
+
+    ["this string contains the null character: \u0000"]
+
+All other Unicode codepoints U+0001 through U+10FFFF are allowed.
+
+Unicode normalization or any other transformation is never performed
+on any strings (string values or object keys). When checking for
+equivalence of strings or object keys, the comparison is performed
+byte by byte between the original UTF-8 representations of the
+strings.
+
+Numbers
+=======
+
+Real vs. Integer
+----------------
+
+JSON makes no distinction between real and integer numbers; Jansson
+does. Real numbers are mapped to the ``double`` type and integers to
+the ``json_int_t`` type, which is a typedef of ``long long`` or
+``long``, depending on whether ``long long`` is supported by your
+compiler or not.
+
+A JSON number is considered to be a real number if its lexical
+representation includes one of ``e``, ``E``, or ``.``; regardless if
+its actual numeric value is a true integer (e.g., all of ``1E6``,
+``3.0``, ``400E-2``, and ``3.14E3`` are mathematical integers, but
+will be treated as real values).
+
+All other JSON numbers are considered integers.
+
+When encoding to JSON, real values are always represented
+with a fractional part; e.g., the ``double`` value 3.0 will be
+represented in JSON as ``3.0``, not ``3``.
+
+Overflow, Underflow & Precision
+-------------------------------
+
+Real numbers whose absolute values are too small to be represented in
+a C ``double`` will be silently estimated with 0.0. Thus, depending on
+platform, JSON numbers very close to zero such as 1E-999 may result in
+0.0.
+
+Real numbers whose absolute values are too large to be represented in
+a C ``double`` will result in an overflow error (a JSON decoding
+error). Thus, depending on platform, JSON numbers like 1E+999 or
+-1E+999 may result in a parsing error.
+
+Likewise, integer numbers whose absolute values are too large to be
+represented in the ``json_int_t`` type (see above) will result in an
+overflow error (a JSON decoding error). Thus, depending on platform,
+JSON numbers like 1000000000000000 may result in parsing error.
+
+Parsing JSON real numbers may result in a loss of precision. As long
+as overflow does not occur (i.e. a total loss of precision), the
+rounded approximate value is silently used. Thus the JSON number
+1.000000000000000005 may, depending on platform, result in the
+``double`` value 1.0.
+
+Signed zeros
+------------
+
+JSON makes no statement about what a number means; however Javascript
+(ECMAscript) does state that +0.0 and -0.0 must be treated as being
+distinct values, i.e. -0.0 |not-equal| 0.0. Jansson relies on the
+underlying floating point library in the C environment in which it is
+compiled. Therefore it is platform-dependent whether 0.0 and -0.0 will
+be distinct values. Most platforms that use the IEEE 754
+floating-point standard will support signed zeros.
+
+Note that this only applies to floating-point; neither JSON, C, or
+IEEE support the concept of signed integer zeros.
+
+.. |not-equal| unicode:: U+2260
+
+Types
+-----
+
+No support is provided in Jansson for any C numeric types other than
+``json_int_t`` and ``double``. This excludes things such as unsigned
+types, ``long double``, etc. Obviously, shorter types like ``short``,
+``int``, ``long`` (if ``json_int_t`` is ``long long``) and ``float``
+are implicitly handled via the ordinary C type coercion rules (subject
+to overflow semantics). Also, no support or hooks are provided for any
+supplemental "bignum" type add-on packages.

+
+Compiling and Installing Jansson
+================================
+
+The Jansson source is available at
+http://www.digip.org/jansson/releases/.
+
+Unix-like systems
+-----------------
+
+Unpack the source tarball and change to the source directory:
+
+.. parsed-literal::
+
+    bunzip2 -c jansson-|release|.tar.bz2 | tar xf -
+    cd jansson-|release|
+
+The source uses GNU Autotools (autoconf_, automake_, libtool_), so
+compiling and installing is extremely simple::
+
+    ./configure
+    make
+    make check
+    make install
+
+To change the destination directory (``/usr/local`` by default), use
+the ``--prefix=DIR`` argument to ``./configure``. See ``./configure
+--help`` for the list of all possible installation options. (There are
+no options to customize the resulting Jansson binary.)
+
+The command ``make check`` runs the test suite distributed with
+Jansson. This step is not strictly necessary, but it may find possible
+problems that Jansson has on your platform. If any problems are found,
+please report them.
+
+If you obtained the source from a Git repository (or any other source
+control system), there's no ``./configure`` script as it's not kept in
+version control. To create the script, the build system needs to be
+bootstrapped. There are many ways to do this, but the easiest one is
+to use ``autoreconf``::
+
+    autoreconf -vi
+
+This command creates the ``./configure`` script, which can then be
+used as described above.
+
+.. _autoconf: http://www.gnu.org/software/autoconf/
+.. _automake: http://www.gnu.org/software/automake/
+.. _libtool: http://www.gnu.org/software/libtool/
+
+
+Other Systems
+-------------
+
+On Windows and other non Unix-like systems, you may be unable to run
+the ``./configure`` script. In this case, follow these steps. All the
+files mentioned can be found in the ``src/`` directory.
+
+1. Create ``jansson_config.h``. This file has some platform-specific
+   parameters that are normally filled in by the ``./configure``
+   script:
+
+   - On Windows, rename ``jansson_config.h.win32`` to ``jansson_config.h``.
+
+   - On other systems, edit ``jansson_config.h.in``, replacing all
+     ``@variable@`` placeholders, and rename the file to
+     ``jansson_config.h``.
+
+2. Make ``jansson.h`` and ``jansson_config.h`` available to the
+   compiler, so that they can be found when compiling programs that
+   use Jansson.
+
+3. Compile all the ``.c`` files (in the ``src/`` directory) into a
+   library file. Make the library available to the compiler, as in
+   step 2.
+
+
+Building the Documentation
+--------------------------
+
+(This subsection describes how to build the HTML documentation you are
+currently reading, so it can be safely skipped.)
+
+Documentation is in the ``doc/`` subdirectory. It's written in
+reStructuredText_ with Sphinx_ annotations. To generate the HTML
+documentation, invoke::
+
+   make html
+
+and point your browser to ``doc/_build/html/index.html``. Sphinx_ 1.0
+or newer is required to generate the documentation.
+
+.. _reStructuredText: http://docutils.sourceforge.net/rst.html
+.. _Sphinx: http://sphinx.pocoo.org/
+
+
+Compiling Programs that Use Jansson
+===================================
+
+Jansson involves one C header file, :file:`jansson.h`, so it's enough
+to put the line
+
+::
+
+    #include <jansson.h>
+
+in the beginning of every source file that uses Jansson.
+
+There's also just one library to link with, ``libjansson``. Compile and
+link the program as follows::
+
+    cc -o prog prog.c -ljansson
+
+Starting from version 1.2, there's also support for pkg-config_::
+
+    cc -o prog prog.c `pkg-config --cflags --libs jansson`

+Tutorial
+********
+
+.. highlight:: c
+
+In this tutorial, we create a program that fetches the latest commits
+of a repository in GitHub_ over the web. One of the response formats
+supported by `GitHub API`_ is JSON, so the result can be parsed using
+Jansson.
+
+To stick to the the scope of this tutorial, we will only cover the the
+parts of the program related to handling JSON data. For the best user
+experience, the full source code is available:
+:download:`github_commits.c`. To compile it (on Unix-like systems with
+gcc), use the following command::
+
+    gcc -o github_commits github_commits.c -ljansson -lcurl
+
+libcurl_ is used to communicate over the web, so it is required to
+compile the program.
+
+The command line syntax is::
+
+    github_commits USER REPOSITORY
+
+``USER`` is a GitHub user ID and ``REPOSITORY`` is the repository
+name. Please note that the GitHub API is rate limited, so if you run
+the program too many times within a short period of time, the sever
+starts to respond with an error.

+
+The GitHub Commits API
+======================
+
+The `GitHub commits API`_ is used by sending HTTP requests to URLs
+starting with ``http://github.com/api/v2/json/commits/``. Our program
+only lists the latest commits, so the rest of the URL is
+``list/USER/REPOSITORY/BRANCH``, where ``USER``, ``REPOSITORY`` and
+``BRANCH`` are the GitHub user ID, the name of the repository, and the
+name of the branch whose commits are to be listed, respectively.
+
+GitHub responds with a JSON object of the following form:
+
+.. code-block:: none
+
+    {
+        "commits": [
+            {
+                "id": "<the commit ID>",
+                "message": "<the commit message>",
+                <more fields, not important to this tutorial>
+            },
+            {
+                "id": "<the commit ID>",
+                "message": "<the commit message>",
+                <more fields, not important to this tutorial>
+            },
+            <more commits...>
+        ]
+    }
+
+In our program, the HTTP request is sent using the following
+function::
+
+    static char *request(const char *url);
+
+It takes the URL as a parameter, preforms a HTTP GET request, and
+returns a newly allocated string that contains the response body. If
+the request fails, an error message is printed to stderr and the
+return value is *NULL*. For full details, refer to :download:`the code
+<github_commits.c>`, as the actual implementation is not important
+here.
+
+.. _GitHub commits API: http://develop.github.com/p/commits.html
+
+.. _tutorial-the-program:
+
+The Program
+===========
+
+First the includes::
+
+    #include <string.h>
+    #include <jansson.h>
+
+Like all the programs using Jansson, we need to include
+:file:`jansson.h`.
+
+The following definitions are used to build the GitHub commits API
+request URL::
+
+   #define URL_FORMAT   "http://github.com/api/v2/json/commits/list/%s/%s/master"
+   #define URL_SIZE     256
+
+The following function is used when formatting the result to find the
+first newline in the commit message::
+
+    /* Return the offset of the first newline in text or the length of
+       text if there's no newline */
+    static int newline_offset(const char *text)
+    {
+        const char *newline = strchr(text, '\n');
+        if(!newline)
+            return strlen(text);
+        else
+            return (int)(newline - text);
+    }
+
+The main function follows. In the beginning, we first declare a bunch
+of variables and check the command line parameters::
+
+    size_t i;
+    char *text;
+    char url[URL_SIZE];
+
+    json_t *root;
+    json_error_t error;
+    json_t *commits;
+
+    if(argc != 3)
+    {
+        fprintf(stderr, "usage: %s USER REPOSITORY\n\n", argv[0]);
+        fprintf(stderr, "List commits at USER's REPOSITORY.\n\n");
+        return 2;
+    }
+
+Then we build the request URL using the user and repository names
+given as command line parameters::
+
+    snprintf(url, URL_SIZE, URL_FORMAT, argv[1], argv[2]);
+
+This uses the ``URL_SIZE`` and ``URL_FORMAT`` constants defined above.
+Now we're ready to actually request the JSON data over the web::
+
+    text = request(url);
+    if(!text)
+        return 1;
+
+If an error occurs, our function ``request`` prints the error and
+returns *NULL*, so it's enough to just return 1 from the main
+function.
+
+Next we'll call :func:`json_loads()` to decode the JSON text we got
+as a response::
+
+    root = json_loads(text, 0, &error);
+    free(text);
+
+    if(!root)
+    {
+        fprintf(stderr, "error: on line %d: %s\n", error.line, error.text);
+        return 1;
+    }
+
+We don't need the JSON text anymore, so we can free the ``text``
+variable right after decoding it. If :func:`json_loads()` fails, it
+returns *NULL* and sets error information to the :type:`json_error_t`
+structure given as the second parameter. In this case, our program
+prints the error information out and returns 1 from the main function.
+
+Now we're ready to extract the data out of the decoded JSON response.
+The structure of the response JSON was explained in section
+:ref:`tutorial-github-commits-api`.
+
+First, we'll extract the ``commits`` array from the JSON response::
+
+    commits = json_object_get(root, "commits");
+    if(!json_is_array(commits))
+    {
+        fprintf(stderr, "error: commits is not an array\n");
+        return 1;
+    }
+
+This is the array that contains objects describing latest commits in
+the repository. We check that the returned value really is an array.
+If the key ``commits`` doesn't exist, :func:`json_object_get()`
+returns *NULL*, but :func:`json_is_array()` handles this case, too.
+
+Then we proceed to loop over all the commits in the array::
+
+    for(i = 0; i < json_array_size(commits); i++)
+    {
+        json_t *commit, *id, *message;
+        const char *message_text;
+
+        commit = json_array_get(commits, i);
+        if(!json_is_object(commit))
+        {
+            fprintf(stderr, "error: commit %d is not an object\n", i + 1);
+            return 1;
+        }
+    ...
+
+The function :func:`json_array_size()` returns the size of a JSON
+array. First, we again declare some variables and then extract the
+i'th element of the ``commits`` array using :func:`json_array_get()`.
+We also check that the resulting value is a JSON object.
+
+Next we'll extract the commit ID and commit message, and check that
+they both are JSON strings::
+
+        id = json_object_get(commit, "id");
+        if(!json_is_string(id))
+        {
+            fprintf(stderr, "error: commit %d: id is not a string\n", i + 1);
+            return 1;
+        }
+
+        message = json_object_get(commit, "message");
+        if(!json_is_string(message))
+        {
+            fprintf(stderr, "error: commit %d: message is not a string\n", i + 1);
+            return 1;
+        }
+    ...
+
+And finally, we'll print the first 8 characters of the commit ID and
+the first line of the commit message. A C-style string is extracted
+from a JSON string using :func:`json_string_value()`::
+
+        message_text = json_string_value(message);
+        printf("%.8s %.*s\n",
+               json_string_value(id),
+               newline_offset(message_text),
+               message_text);
+    }
+
+After sending the HTTP request, we decoded the JSON text using
+:func:`json_loads()`, remember? It returns a *new reference* to the
+JSON value it decodes. When we're finished with the value, we'll need
+to decrease the reference count using :func:`json_decref()`. This way
+Jansson can release the resources::
+
+    json_decref(root);
+    return 0;
+
+For a detailed explanation of reference counting in Jansson, see
+:ref:`apiref-reference-count` in :ref:`apiref`.
+
+The program's ready, let's test it and view the latest commits in
+Jansson's repository::

+Conclusion
+==========
+
+In this tutorial, we implemented a program that fetches the latest
+commits of a GitHub repository using the GitHub commits API. Jansson
+was used to decode the JSON response and to extract the commit data.
+
+This tutorial only covered a small part of Jansson. For example, we
+did not create or manipulate JSON values at all. Proceed to
+:ref:`apiref` to explore all features of Jansson.

+******************
+Upgrading from 1.x
+******************
+
+This chapter lists the backwards incompatible changes introduced in
+Jansson 2.0, and the steps that are needed for upgrading your code.
+
+**The incompatibilities are not dramatic.** The biggest change is that
+all decoding functions now require and extra parameter. Most programs
+can be modified to work with 2.0 by adding a ``0`` as the second
+parameter to all calls of :func:`json_loads()`, :func:`json_loadf()`
+and :func:`json_load_file()`.
+
+
+Compatibility
+=============
+
+Jansson 2.0 is backwards incompatible with the Jansson 1.x releases.
+It is ABI incompatible, i.e. all programs dynamically linking to the
+Jansson library need to be recompiled. It's also API incompatible,
+i.e. the source code of programs using Jansson 1.x may need
+modifications to make them compile against Jansson 2.0.
+
+All the 2.x releases are guaranteed to be backwards compatible for
+both ABI and API, so no recompilation or source changes are needed
+when upgrading from 2.x to 2.y.
+
+
+List of Incompatible Changes
+============================
+
+**Decoding flags**
+    For future needs, a ``flags`` parameter was added as the second
+    parameter to all decoding functions, i.e. :func:`json_loads()`,
+    :func:`json_loadf()` and :func:`json_load_file()`. All calls to
+    these functions need to be changed by adding a ``0`` as the second
+    argument. For example::
+
+        /* old code */
+        json_loads(input, &error);
+
+        /* new code */
+        json_loads(input, 0, &error);
+
+
+**Underlying type of JSON integers**
+    The underlying C type of JSON integers has been changed from
+    :type:`int` to the widest available signed integer type, i.e.
+    :type:`long long` or :type:`long`, depending on whether
+    :type:`long long` is supported on your system or not. This makes
+    the whole 64-bit integer range available on most modern systems.
+
+    ``jansson.h`` has a typedef :type:`json_int_t` to the underlying
+    integer type. :type:`int` should still be used in most cases when
+    dealing with smallish JSON integers, as the compiler handles
+    implicit type coercion. Only when the full 64-bit range is needed,
+    :type:`json_int_t` should be explicitly used.
+
+
+**Maximum encoder indentation depth**
+    The maximum argument of the ``JSON_INDENT()`` macro has been
+    changed from 255 to 31, to free up bits from the ``flags``
+    parameter of :func:`json_dumps()`, :func:`json_dumpf()` and
+    :func:`json_dump_file()`. If your code uses a bigger indentation
+    than 31, it needs to be changed.
+
+
+**Unsigned integers in API functions**
+    Version 2.0 unifies unsigned integer usage in the API. All uses of
+    :type:`unsigned int` and :type:`unsigned long` have been replaced
+    with :type:`size_t`. This includes flags, container sizes, etc.
+    This should not require source code changes, as both
+    :type:`unsigned int` and :type:`unsigned long` are usually
+    compatible with :type:`size_t`.
