+ * @font: a mutable #hb_font_t to use for shaping
+ * @buffer: an #hb_buffer_t to shape
+ * @features: (array length=num_features) (nullable): an array of user
+ *    specified #hb_feature_t or `NULL`
+ * @num_features: the length of @features array
+ * @shaper_list: (array zero-terminated=1) (nullable): a `NULL`-terminated
+ *    array of shapers to use or `NULL`
+ * @min_target_advance: Minimum advance width/height to aim for.
+ * @max_target_advance: Maximum advance width/height to aim for.
+ * @advance: (inout): Input/output advance width/height of the buffer.
+ * @var_tag: (out): Variation-axis tag used for justification.
+ * @var_value: (out): Variation-axis value used to reach target justification.
+ *
+ * See hb_shape_full() for basic details. If @shaper_list is not `NULL`, the specified
+ * shapers will be used in the given order, otherwise the default shapers list
+ * will be used.
+ *
+ * In addition, justify the shaping results such that the shaping results reach
+ * the target advance width/height, depending on the buffer direction.
+ *
+ * If the advance of the buffer shaped with hb_shape_full() is already known,
+ * put that in *advance. Otherwise set *advance to zero.
+ *
+ * This API is currently experimental and will probably change in the future.
+ *
+ * Return value: false if all shapers failed, true otherwise
+ *
+ * XSince: EXPERIMENTAL

+Version 1.6.39 [November 20, 2022]
+  Changed the error handler of oversized chunks (i.e. larger than
+    PNG_USER_CHUNK_MALLOC_MAX) from png_chunk_error to png_benign_error.
+  Fixed a buffer overflow error in contrib/tools/pngfix.
+  Fixed a memory leak (CVE-2019-6129) in contrib/tools/pngcp.
+  Disabled the ARM Neon optimizations by default in the CMake file,
+    following the default behavior of the configure script.
+  Allowed configure.ac to work with the trunk version of autoconf.
+  Removed the support for "install" targets from the legacy makefiles;
+    removed the obsolete makefile.cegcc.
+  Cleaned up the code and updated the internal documentation.

+     *      In brief, a descriptor is a string representing the type of a field or method. Signatures are similar, but more
+     *      complex. Signatures are used to encode declarations written in the Java programming language that use types
+     *      outside the type system of the Java Virtual Machine. They are used to describe the type of any class, interface,
+     *      constructor, method or field whose declaration uses type variables or parameterized types.
+     *
+     *      To parse a descriptor, call typeSignatureToString. To parse a signature, call signatureToString.
+     *
+     *      Note that if the signature string is a single, non-generic item, the call to signatureToString reduces to a call
+     *      to typeSignatureToString. Also note, that if you only wish to parse the first item in a longer signature string,

-     * WARNING:
-     *
-     * There is some nomenclature confusion through much of the BCEL code base with
-     * respect to the terms Descriptor and Signature.  For the offical definitions see:
-     *
-     * @see 
-     * Descriptors in The Java Virtual Machine Specification
-     *
-     * @see 
-     * Signatures in The Java Virtual Machine Specification
-     *
-     * In brief, a descriptor is a string representing the type of a field or method.
-     * Signatures are similar, but more complex.  Signatures are used to encode declarations
-     * written in the Java programming language that use types outside the type system of the
-     * Java Virtual Machine.  They are used to describe the type of any class, interface,
-     * constructor, method or field whose declaration uses type variables or parameterized types.
-     *
-     * To parse a descriptor, call typeSignatureToString.
-     * To parse a signature, call signatureToString.
-     *
-     * Note that if the signature string is a single, non-generic item, the call to
-     * signatureToString reduces to a call to typeSignatureToString.
-     * Also note, that if you only wish to parse the first item in a longer signature
-     * string, you should call typeSignatureToString directly.

-
-     "Derivative Works" shall mean any work, whether in Source or Object
-     form, that is based on (or derived from) the Work and for which the

-     with the Work to which such Contribution(s) was submitted. If You
-     institute patent litigation against any entity (including a
-     cross-claim or counterclaim in a lawsuit) alleging that the Work
-     or a Contribution incorporated within the Work constitutes direct
-     or contributory patent infringement, then any patent licenses
-     granted to You under this License for that Work shall terminate
-     as of the date such litigation is filed.
-
-  4. Redistribution. You may reproduce and distribute copies of the
-     Work or Derivative Works thereof in any medium, with or without

-     (a) You must give any other recipients of the Work or
-         Derivative Works a copy of this License; and
-
-     (b) You must cause any modified files to carry prominent notices
-         stating that You changed the files; and

-         excluding those notices that do not pertain to any part of
-         the Derivative Works; and
-
-     (d) If the Work includes a "NOTICE" text file as part of its
-         distribution, then any Derivative Works that You distribute must
-         include a readable copy of the attribution notices contained
-         within such NOTICE file, excluding those notices that do not
-         pertain to any part of the Derivative Works, in at least one
-         of the following places: within a NOTICE text file distributed
-         as part of the Derivative Works; within the Source form or
-         documentation, if provided along with the Derivative Works; or,
-         within a display generated by the Derivative Works, if and
-         wherever such third-party notices normally appear. The contents
-         of the NOTICE file are for informational purposes only and
-         do not modify the License. You may add Your own attribution
-         notices within Derivative Works that You distribute, alongside
-         or as an addendum to the NOTICE text from the Work, provided
-         that such additional attribution notices cannot be construed
-         as modifying the License.
-
-     You may add Your own copyright statement to Your modifications and
-     may provide additional or different license terms and conditions
-     for use, reproduction, or distribution of Your modifications, or
-     for any such Derivative Works as a whole, provided Your use,
-     reproduction, and distribution of the Work otherwise complies with
-     the conditions stated in this License.
-
-  5. Submission of Contributions. Unless You explicitly state otherwise,
-     any Contribution intentionally submitted for inclusion in the Work
-     by You to the Licensor shall be under the terms and conditions of
-     this License, without any additional terms or conditions.
-     Notwithstanding the above, nothing herein shall supersede or modify
-     the terms of any separate license agreement you may have executed
-     with Licensor regarding such Contributions.
-
-  6. Trademarks. This License does not grant permission to use the trade
-     names, trademarks, service marks, or product names of the Licensor,
-     except as required for reasonable and customary use in describing the
-     origin of the Work and reproducing the content of the NOTICE file.
-
-  7. Disclaimer of Warranty. Unless required by applicable law or
-     agreed to in writing, Licensor provides the Work (and each
-     Contributor provides its Contributions) on an "AS IS" BASIS,
-     WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-     implied, including, without limitation, any warranties or conditions
-     of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-     PARTICULAR PURPOSE. You are solely responsible for determining the
-     appropriateness of using or redistributing the Work and assume any
-     risks associated with Your exercise of permissions under this License.
-
-  8. Limitation of Liability. In no event and under no legal theory,
-     whether in tort (including negligence), contract, or otherwise,
-     unless required by applicable law (such as deliberate and grossly
-     negligent acts) or agreed to in writing, shall any Contributor be
-     liable to You for damages, including any direct, indirect, special,
-     incidental, or consequential damages of any character arising as a
-     result of this License or out of the use or inability to use the
-     Work (including but not limited to damages for loss of goodwill,
-     work stoppage, computer failure or malfunction, or any and all
-     other commercial damages or losses), even if such Contributor
-     has been advised of the possibility of such damages.
-
-  9. Accepting Warranty or Additional Liability. While redistributing
-     the Work or Derivative Works thereof, You may choose to offer,
-     and charge a fee for, acceptance of support, warranty, indemnity,
-     or other liability obligations and/or rights consistent with this
-     License. However, in accepting such obligations, You may act only
-     on Your own behalf and on Your sole responsibility, not on behalf
-     of any other Contributor, and only if You agree to indemnify,
-     defend, and hold each Contributor harmless for any liability
-     incurred by, or claims asserted against, such Contributor by reason
-     of your accepting any such warranty or additional liability.

+ * socket time out, the opened socket is not closed properly. In this test case, the server
+ * is forced to sleep ten seconds and connection time out for client is one second. This
+ * will allow the socket opened and connected, and give the chance for the handshake to be
+ * timed out. Before this fix, the socket is kept opened. Right now the exception will be
