In ~/.elinks/allowed_ecmascript_url_prefixes.txt you must enter list
of urls. For example:
file://
https://buildlogs.pld-linux.org/http://example
If url of document starts with one of given prefixes, then given url is
allowed to execute ecmascript. Start from most often used first.
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
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.
Introduce static int interpreter_count in src/ecmascript/ecmascript.c.
Maintain interpreter_count in ecmascript_get_interpreter and
ecmascript_put_interpreter.
Introduce ecmascript_get_interpreter_count.
Display the number of ECMAScript interpreters that have been allocated
for documents in the Resources dialog box.
cache_entry.id => cache_entry.cache_id
document.id => document.cache_id
ecmascript_interpreter.onload_snippets_owner => .onload_snippets_cache_id
This is a combination of:
commit 232c07aa7f
bug 1009: id variables renamed, added document_id to the document.
commit 6007043458bf8f14abfc18b9db60785bdc0279f6
Revert addition of document.document_id
Anything that frees struct form_view must now call the new function
ecmascript_detach_form_view. This function should then clear out any
dangling pointers, but that has not yet been implemented.
Anything that frees or reallocates struct form_state must now call the
new functions ecmascript_detach_form_state or ecmascript_moved_form_state.
These functions should then clear out any dangling pointers, but that has
not yet been implemented.
cached->id => cached->cache_id
document->id => document->cache_id
onload_snippets_owner => onload_snippets_document_id
Added the distinct document->document_id.
Always reset ecmascript when a document changes for example a next chunk
of it is loaded.
There were conflicts in src/document/css/ because 0.12.GIT switched
to LIST_OF(struct css_selector) and 0.13.GIT switched to struct
css_selector_set. Resolved by using LIST_OF(struct css_selector)
inside struct css_selector_set.
Add ecmascript_interpreter.backend_nesting, increment it when
beginning to evaluate an expression, and decrement it when evaluation
finishes. Then assert that it is zero in ecmascript_put_interpreter.
This detects bug 957 and similar ones before they corrupt memory.
