- * \par Thread Safety
- *
- * Jansson (as of 2.4) provides fairly weak thread safety guarantees. The
- * Asterisk wrapper improves upon that slightly. The remaining refcounting
- * problems are issues when slicing/sharing/mixing instances between JSON
- * objects and arrays, which we avoid.
- *
- * The \c ast_json_dump_* functions are thread safe for multiple concurrent
- * dumps of the same object, so long as the concurrent dumps start from the same
- * \c root object. But if an object is shared by other JSON objects/arrays, then
- * concurrent dumps of the outer objects/arrays are not thread safe. This can be
- * avoided by using ast_json_deep_copy() when sharing JSON instances between
- * objects.
- *
- * The ast_json_ref() and ast_json_unref() functions are thread safe. Since the
- * Asterisk wrapper exclusively uses the reference stealing API, Jansson won't
- * be performing many refcount modifications behind our backs. There are a few
- * exceptions.
- *
- * The first is the transitive json_decref() that occurs when \ref
- * AST_JSON_OBJECT and \ref AST_JSON_ARRAY instances are deleted. This can be
- * avoided by using ast_json_deep_copy() when sharing JSON instances between
- * objects.
- *
- * The second is when using the reference borrowing specifier in
- * ast_json_pack() (capital \c O). This can be avoided by using the reference
- * stealing specifier (lowercase \c o) and wrapping the JSON object parameter
- * with ast_json_ref() for an explicit ref-bump.

+From: Corey Farrell <git@cfware.com>
+Date: Tue, 13 Feb 2018 04:35:37 -0500
+Subject: [PATCH 01/22] Improve test coverage.
+
+Changes to test/ removed for bundled use in Asterisk.
+
+* Test equality of different length strings.
+* Add tab to json_pack whitespace test.
+* Test json_sprintf with empty result and invalid UTF.
+* Test json_get_alloc_funcs with NULL arguments.
+* Test invalid arguments.
+* Add test_chaos to test allocation failure code paths.
+* Remove redundant json_is_string checks from json_string_equal and
+  json_string_copy.  Both functions are static and can only be called
+  with a json string.
+
+Fixes to issues found by test_chaos:
+* Fix crash on OOM in pack_unpack.c:read_string().
+* Unconditionally free string in string_create upon allocation failure.
+  Update load.c:parse_value() to reflect this.  This resolves a leak on
+  allocation failure for pack_unpack.c:pack_string() and
+  value.c:json_sprintf().
+
+Although not visible from CodeCoverage these changes significantly
+increase branch coverage.  Especially in src/value.c where we previously
+covered 67.4% of branches and now cover 96.3% of branches.
