* 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.

* 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

* 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

* JS: Split concept of JS context into heap and threadDaniel Silverstone2020-03-217-56/+86
| | | | | | | | | 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>

* fs_backing_store: Remove cache on failure to initDaniel Silverstone2020-02-241-3/+17
| | | | | | | | | | If we fail to init the control file for reasons other than it not being found, we blow away the cache in its entirety and then try again. We warn if the removal fails, but carry on regardless since right now the worst that'll happen is that we'll end up with more on disk than we know about in the cache.

* fetch: Bump last_msg rather than always assigning itDaniel Silverstone2020-02-241-1/+3
| | | | | | | | | | If we are aborting a cURL fetch then it's possible entry to cURL to clean up could cause a PROGRESS message to happen which we need to not reset last_msg for, otherwise we spuriously attempt to send an ERROR message during abort which is not a safe time for our message callback to be used.
