SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.
Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings
Each C function that can be called as a method of an ECMAScript object
is typically listed in a spidermonkeyFunctionSpec array and has a
comment that shows the name of the array and the name of the method.
For example, elinks_alert has a comment /* @elinks_funcs{"alert"} */
because elinks_funcs[] contains an element { "alert", elinks_alert, 1 }.
When some of those functions were split into outer and inner functions
for SpiderMonkey 1.8.5 compatibility, the comments were attached to
the inner functions, which contain the bulk of the code. Move the
comments to the outer functions, to which the array elements point.
forms_item declared a variable (jsval val), passed its address to
forms_item2, and set it as the return value. However, forms_item2
could return without initializing the jsval, especially if given too
many arguments. Fix by initializing to JSVAL_VOID right away.
I'm not sure that is the correct value to return in such cases,
but at least it's better than risking a crash.
Likewise in form_elements_item and form_elements_namedItem.
Add session_class, which defines a JSObject wrapper for struct session.
Add location_array_class, which defines a JSObject wrapper for struct
ses_history. The "history" member of struct session is a struct
ses_history, which is a linked list of struct location.
Add a pointer from struct session to the session_class object and the
location_array object.
Add smjs_get_session_object to return a session_class JSObject wrapper for
a given struct session.
Add smjs_get_session_location_array_object to return a location_array_class
JSObject wrapper for a given struct session.
Add "session" property to the "elinks" object, which uses
smjs_get_session_object to get a JSObject wrapper for smjs_ses.
Add smjs_location_array_get_property, which allows indexing
a location_array object using a positive number for history forward or
a negative number for history backward.
Add session_props, session_get_property, session_set_property,
session_funcs, smjs_session_goto_url (which implements the "goto" method),
and smjs_init_session_interface for session_class.
Add session_construct, which creates a new tab and returns the JSObject
session_class wrapper.
Add session_finalize and smjs_location_array_finalize, which clear the
pointers between struct session and the JSObject wrappers in question.
Add smjs_detach_session_object, which clears the pointers between a given
struct session and the corresponding JSObject wrappers.
In destroy_session, call smjs_detach_session_object.
Add jsval_to_object helper in ecmascript/spidermonkey/util.h;
jsval_to_object is used in smjs_session_goto_url.
Modify delayed_goto_uri_frame to allow the target to be NULL.
smjs_session_goto_url needs this modification.
Implement new heartbeat code to catch runaway execution of document
ECMAScript code. The old code uses JS_SetBranchCallback which is
deprecated in new versions of SpiderMonkey. The new code uses setitimer(2)
and the JS_SetOperationCallback and JS_TriggerOperationCallback interfaces,
introduced in SpiderMonkey 1.8.1. Compatibility with both the old
JS_SetBranchCallback and the new interfaces is maintained.
