* Box Conversion: Cancel conversion during html_destroyDaniel Silverstone2019-08-234-3/+38
| | | | | | | | If dom_to_box is still in progress when we destroy an HTML content, we need to cancel the conversion otherwise we will end up with a scheduled callback into infinity. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

| | | | And assert that floats have a float_container.
* Excise the llcache query pathway.Daniel Silverstone2019-08-053-50/+0
| | | | | | | | In further preparation for the auth and cert queries being handled as special contents from `about:` this excises the query pathway from the llcache pretty much entirely. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

* Content messages: Remove ERRORCODE, rework ERRORDaniel Silverstone2019-08-053-18/+6
| | | | | | | This reworks CONTENT_MSG_ERROR to be structured data and removes the CONTENT_MSG_ERRORCODE message kind. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

* html: Mirror gadget values in and out of the DOMDaniel Silverstone2019-08-046-1/+169
| | | | | | | | | Currently only supporting text input, password input, and hidden input, along with text areas, this mirrors the text values in and out of the DOM, allowing JS to adjust the gadget values and for the gadget values to be interrogated from JS.

* change browser_window_mouse_click to use unscaled coordinatesVincent Sanders2019-08-031-5/+5
| | | | | this means frontends no longer need to scale mouse click events thus simplifying their implementation.

* html_interaction.c: Default node to <HTML> nodeDaniel Silverstone2019-08-011-1/+1
| | | | | | | | | | | In order to cope when an entire document is `visibility: hidden` we default to the <HTML> node when interacting with the document to ensure we don't drop off the end of the box model without identifying at least one node to fire events at. This resolves #2658 Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>

* html.c: Correct ordering for reformat timeDaniel Silverstone2019-06-051-1/+1
| | | | | | Fix a minor bug where we'd likely never end up reformatting. Signed-off-by: Daniel Silverstone <dsilvers@digital-scurf.org>
* html_script.c: html_script_exec() reqacquire script ptrDaniel Silverstone2019-06-011-0/+5
| | | | | | | | | Since executing a script can cause more scripts to be appended to the script array, and that can cause a reallocation which might move the script array, reacquire the script pointer after running the script so that we don't wander off into the reeds.

* CSS: Update for change to libcss append sheet API.Michael Drake2019-05-041-1/+7
| | | | | | | | | | | | | | When appending stylesheets to the selection context, it now takes the media query string associated with the sheet, rather than the type bitfield. TODO: We need to pass all the sheets in, with their full media query string, rather than filtering it ourselves and setting the ones we pass in to "screen".

* validate the form button element type attribute as per specVincent Sanders2019-02-221-4/+16
| | | | | | | https://html.spec.whatwg.org/multipage/form-elements.html#attr-button-type says if the type attribute is anything but "reset" or "button" it is of "submit" type. The previous logic was incorrect and only used the button if its type was explicitly submit and noting else.
* HTML handler: Reformat passing viewport height when triggered by object.Michael Drake2019-02-171-3/+3
| | | | | | Previously we correctly used the viewport width, but we were using the document height instead of viewport height when an HTML child content triggered a reformat of the parent HTML document.

* rewrite form_successful_controls_dom as form_dom_to_dataVincent Sanders2018-09-291-556/+883
| | | | | | | | | | | | | | | | | | | | | | | | Trying to reason about error propagation and resource leakage within the form submission code was impossible because of the form_successful_controls_dom function. This function was over six hundred lines long, had twenty six top level local variables and six levels of indent in places. This commit splits it out into thirteen shorter and more obvious functions. The resulting operation is identical except errors are properly propagated (all failures were reported as out of memory) and resource management can be reasoned about. The compiler appears to inline the entirety of the code from form_submit() down excepting a handful of leaf functions. This results in similar code output size as previous implementation. The new implementation has a greater number of variables passed to sub functions than desirable because multiple character sets are required to encode names and values in the multipart data list. However as noted the compiler effectively inlines all these functions so this does not actually become a major problem.
