* 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.

* 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>
* JS: Split concept of JS context into heap and threadDaniel Silverstone2020-03-214-27/+28
| | | | | | | | | 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>

* 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.

* Allow contents to indicate if they believe they may not be secure.Daniel Silverstone2019-12-014-0/+79
| | | | | | | | | | HTML contents reference many other objects. The browser window needs to know if any of them may not be secure, in which case it needs to report that in its page state. If other content types might refer to sub-contents, they will need to define the callback too. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

* Remove redundant drag handling for content selectionVincent Sanders2019-11-121-10/+0
| | | | | | | This redundant code was added by: 4747bbbfb21d645f950149bbe173a2618cd3eba9 HTML drags now go via content msg. and then added again with: c2a718075ad321a9cf4678e72645acda5c3471a9 A load of refactoring of how content selection and input work.

* Content: Remove redundant and unused redraw message fields.Michael Drake2019-11-111-31/+16
| | | | | | | | | | This was archaic support for rendering images as "overlays", and avoiding a redraw via the browser window redraw and HTML contents. Basically it was "plot this image here", but it was too error prone, so it was removed a long time ago. These are some last vestiges that made the redraw message look more complex than it is.
