v8 14.1 added an EmbedderDataTypeTag to the v8::Object aligned internal field
pointer accessors and 14.2 removed the versions without one, so the generated
code did not compile with Node.js 26. The new SWIGV8_ALIGNED_POINTER_GET and
SWIGV8_ALIGNED_POINTER_SET macros select between them, switching at 14.2 as
14.1 only has the tagged setter.
The default tag is used rather than a SWIG specific one. The tag used when
setting must match the tag used when getting, and modules pass proxy objects
between each other, so a SWIG specific tag would stop a module wrapped by an
older SWIG being read by one wrapped by a newer SWIG.
v8 14.3 similarly added a type tag to v8::External and deprecated the versions
without one, which is fatal as the examples are compiled with -Werror.
SWIGV8_EXTERNAL_NEW now selects between them and the new SWIGV8_EXTERNAL_VALUE
macro does the same for reading the value back.
Node.js 26 is added to the CI test matrix for both the node and napi engines.
The minimum supported v8 version is unchanged at 7.4.

v8 12.6 deprecated FunctionCallbackInfo::Holder() and 13.5 removed it, so the
generated code did not compile with Node.js 24. This() has been available for
as long as SWIG has supported v8 and is the documented replacement, so it is
used unconditionally via the new SWIGV8_ARGS_THIS macro.
PropertyCallbackInfo needs a version check as its Holder() replacement,
HolderV2(), was only added in v8 12.7 - SWIGV8_INFO_HOLDER handles this.
v8 13.3 added Utf8LengthV2 and WriteUtf8V2 and deprecated Utf8Length and
WriteUtf8, which is fatal as the examples are compiled with -Werror. The
existing SWIGV8_UTF8_LENGTH and SWIGV8_WRITE_UTF8 macros now select between
them. The buffer size passed to SWIGV8_WRITE_UTF8 now always includes room
for the NUL and the returned count includes the NUL, matching WriteUtf8V2
with WriteFlags::kNullTerminate.
The ARGC/ARGV typemap relied on the old behaviour of passing a buffer size
excluding the NUL. With WriteUtf8V2 that silently truncates the last
character while still returning the expected count, so the length check
would have passed for a corrupted string.
Node.js 24 is added to the CI test matrix for both the node and napi engines.
The minimum supported v8 version is unchanged at 7.4.

This is the oldest we are able to test in CI, and only then via it being
the version use by the oldest node.js we can test in CI. We have no
direct testing with v8 in CI currently, and it seems hard to
v8_shell.cxx no longer building with more recent v8 versions.
See #2537
and exception specifications for native types.
Now the raised exception contains the string value as the exception
message instead of just the C/C++ type of the exception.
R exceptions were completely swallowed beforehand
Add testcase for previous commit.
Add missing assert for future type conversions support that will use
the heap instead of pointer casts (for smart pointer type conversions).
Closes#1963
* array_fix:
add javascript_arays.i fix to changes file
Convert javascript_arrays.i example into testcase
Update .gitignore for java doxygen output
Javascript code formatting corrections
Fix Javascript arrays for modern node versions
Fix for new SWIGV8_ARRAY_NEW definition
Proper array typemaps in Javascript
The old Node.js versions don't treat v8::Handle and v8::Local as
the same types, and the latest versions (v12 and newer) have
removed v8::Handle at all.
This patch introduces the following macros that use v8::Handle or
v8::Local depending on the selected Node.js version:
- SWIGV8_ARRAY
- SWIGV8_FUNCTION_TEMPLATE
- SWIGV8_OBJECT
- SWIGV8_OBJECT_TEMPLATE
- SWIGV8_VALUE
Overloading support for Javascript is generally incomplete as there are
no typecheck typemaps, so the overloading and NULL support added here
doesn't work and won't work until the typecheck typemaps are
implemented.
* js-v8-52-tests:
fixed nvm
node tests: use provided version if present
travis tests for different node versions
fix travis tests
Test NodeJS 4, 6, 8, and 10
Remove warnings on Node 6.x aka V8 5.0 and 5.1
Add Node 7.x aka V8 5.2+ support
The proposed changes targetted at 5.2 (or 5.4 to be more precise, since there is no Node release with V8 5.2 or 5.3) work for lower versions as well and bust the deprecation warnings there.
* Use WeakCallbackInfo instead of WeakCallbackData
* Use GetPrivate instead of GetHiddenValue
* Adopted new signature for SetWeak to support destructor calling
* SetAccessor deprecation fixed
* Proper version checks where applicable
