* remove forward declarationsVincent Sanders2020-04-262-2044/+2170
| | | | | reorder module to remove need for forward function declarations. remove unecessary and confusing parameter macros
* Window: Do not get stuck if callbacks are in-train during compartment closeDaniel Silverstone2020-04-251-1/+30
| | | | | | | | | When we close the JS compartment we try and cancel all callbacks so that they do not fire after the compartment is closed. However if we have in-train callbacks, they can gum up the closedown and so we need to check and if we've done all we can, we break out of the callback removal loop.

* refactor html mouse actionVincent Sanders2020-04-131-482/+738
| | | | | | | | | | | | | | | | | This reduces the source complexity of the html_mouse_action() previously this was a single function of several thousand lines with over 30 local variables allocated on the stack. Variables are now mostly held in a single static structure which drasticaly reduces the size of stack frame required and improves lookup locality. The generated code does cause two additional function calls as the compiler avoids inlining the sub functions. The optimiser seems to produce somewhat better code within the sub functions. In the final analysis there appears to be no significant performance loss or gain with this change, just more readable source.
* html: Also close js thread on html_stop()Daniel Silverstone2020-03-291-0/+4

* HTML: Use new js_closethread()Daniel Silverstone2020-03-221-1/+7

* Window: Add flag to ensure we don't set timeouts after closeDaniel Silverstone2020-03-221-0/+14
| | | | Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* JS: Add concept of js_closethreadDaniel Silverstone2020-03-223-4/+42
| | | | | | | In order to better model content close vs destroy, add the concept of closing a thread to the JS interface. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* JS: Move ownership of jsthread from browser to htmlcDaniel Silverstone2020-03-223-27/+8
| | | | | | | | Since it makes more sense for the htmlc to be responsible for when the JS thread gets destroyed, move its lifetime from the responsibility of the browser window to the html content. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* Dukky: Make heaps refcounted tooDaniel Silverstone2020-03-221-2/+18
| | | | Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* Dukky: Add refcounting to threadsDaniel Silverstone2020-03-211-5/+59
| | | | | | | | | In order to cope with threads which manage to navigate entirely while executing (sadly possible) we need to handle the possibility that a thread is destroyed by the browser but still needs to live until it returns from whatever exec it was doing at the time.

* Dukky: Upgrade dukky binding to support new heap/thread splitDaniel Silverstone2020-03-213-95/+121
| | | | | | | | Update the duktape bindings and dukky interface to support the new JS heap/thread split. Heaps may have multiple active threads though in general there will only be 2 at a time. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* JS: Add concept of thread destroyDaniel Silverstone2020-03-212-0/+18
| | | | Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* JS: Split concept of JS context into heap and threadDaniel Silverstone2020-03-216-53/+83
| | | | | | | | | In preparation for proper splitting of Javascript support into heaps and threads, this renames the types and corrects the no-js builds to still work. At this time no substantive change in semantics exists, and the duktape build won't work. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

* JS: Add Element::attributes and NamedNodeMap to handle itDaniel Silverstone2020-02-213-0/+103
| | | | | | | This is a *very* rudimentary implementation lacking most of the functionality of NamedNodeMap but it's enough to get jQuery 1.12.4 up. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* JS Generics: Add a NodeMap proxy builderDaniel Silverstone2020-02-211-0/+23
| | | | Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* Element: support innerHTMLDaniel Silverstone2020-02-211-0/+123
| | | | | | | | To get us further along the JavaScript pathway, support the getter and setter for innerHTML. The getter always returns an empty string for now, but the setter works. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* JS: Add DOMImplementation::createHTMLDocumentDaniel Silverstone2020-02-213-0/+142

* HTML: Complete content state machine after async scriptDaniel Silverstone2020-02-213-5/+29
| | | | | | | | | The async script completion process needs to complete the content state machine so that browser throbbers eventually stop once async scripts have fetched and run, even if that happens *after* conversion finishes. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* re-order config include so strcasecmp is correctly detected on RISC OS/win32Vincent Sanders2019-12-221-1/+2

* html_script: Count sync scripts to prevent unpausing earlyDaniel Silverstone2019-12-191-2/+11
| | | | | | | | | If there is more than one incomplete sync script then it's important that we don't unpause hubbub too early. This commit adds a counter so that if there're unfinished sync scripts in the set, we don't unpause until the last one completes. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

* HTML redraw: Never draw box scrollbars for textareas.Michael Drake2019-12-091-0/+1
| | | | | | | The scrollbars for textareas are rendered by the widget. This stops us from putting broken scrollbars over the top of the textarea's own scrollbars.
* webp: NetSurf bitmap format is RGBA.Michael Drake2019-12-081-1/+3
