I kept the first patch (`Remember if timer was blocked.`) to avoid SetTimer on timers that weren't killed, mostly because it would apply on every task (which is likely to execute way faster than the ms granularity), not sure if it would skew the timer in such case.
The other patches are split, with tests now showing why they're needed. Some places where wine-gecko callbacks into us and in which we call into external code need to be treated the same as a recursive task since it can end up in a message loop.
I haven't supplied all of them from the previous MR, mostly because I didn't find a way to test those (e.g. show context menu, and the gecko async navigation).
-- v4: mshtml: Don't process tasks recursively from Gecko events. mshtml: Don't process tasks recursively from script runners. mshtml: Don't process tasks recursively. mshtml: Remember if timer was blocked. mshtml: Don't cast to int to bound the timer.

It's a wine-gecko callback that can lead to a message loop (calling into external code).

This is a repost of an email I sent on Monday that clearly didn't come through (and it isn't even using the wine-gitlab bridge, since I replied to the gitlab notification itself; I wonder when this will get fixed because it's extremely annoying and it's _only_ gitlab that has issues).
This got broken during the server upgrade, hopefully it's working again now.
Jacek Caban (@jacek) commented about dlls/mshtml/mutation.c:
static nsresult NSAPI nsRunnable_Run(nsIRunnable *iface) {
- thread_data_t *thread_data = get_thread_data(FALSE); nsRunnable *This = impl_from_nsIRunnable(iface);
- nsresult nsres;
- if(!thread_data)
return NS_ERROR_OUT_OF_MEMORY;
- return This->proc(This->doc, This->arg1, This->arg2);
- thread_data->tasks_locked++;
- nsres = This->proc(This->doc, This->arg1, This->arg2);
- if(!--thread_data->tasks_locked)
unblock_tasks_and_timers(thread_data);- return nsres;
I think it would make sense to abstract thread data handling details from places like this or event handler. This could look like: ``` block_task_processing(); This->proc(...); unblock_task_processing(); ```
Maybe we could even use the same helpers in `hidden_proc` itself.
That's because those tests first create two async XHRs and then a sync XHR. It appears that gecko will simply hang if we don't process the async XHR tasks in the sync XHR message loop…
I guess it's about use of tasks in `nsio.c`.
In general, it's not tasks themselves that we need to block here, but rather script (or host) visible notifications. We don't want to stall other bindings during sync XHR just like we don't want to stop repainting GUI. What we want is to give the script an impression that it's not processed. And yeah, such synchronous operations in a middle of otherwise asynchronous environment are broken by design, that's why sync XHRs are deprecated. That said, it's probably fine if we don't get it exactly right.

Sadly, it looks like it is still not working.

Yeah, what I mean is that we're supposed to block tasks (the point of the MR) if we're in a nested message loop. This works fine without sync XHRs. For sync XHRs, Gecko uses a message loop and expects the tasks to be processed (probably the ones you said in `nsio.c`).
Now what if a nested message loop (that should block all tasks!) calls sync XHR send() at some point? It has to process the tasks, else Gecko hangs. So, I took the "safe" approach and process all tasks in such case—i.e. behavior as before this MR (I set `tasks_locked` to 0 during sync XHR send, then back to its previous value; nested message loops within sync XHR send will still not get processed and that's fine).
Granted, I doubt it will happen in practice, so it's probably good enough, but if it does we can probably revisit it. We should probably keep it simple for now.
BTW note that it's more than just the sync XHR io tasks themselves. As I said, even tasks related to prior async XHRs in the xhr.js tests had to be processed for some reason (which have nothing to do with the sync XHR), else it hanged. That's why I gave up trying to "only process tasks related to sync XHR" (IO or otherwise) which was my idea originally that failed, and went with something simpler for such a niche case.
