Summary: Windowed plugin shouldn't consume reserved shortcut keys of chrome → [Win] Windowed plugin shouldn't consume reserved shortcut keys of chrome
PluginInstanceChild::PluginWindowProcInternal() should use switch-case statement at checking each message because adding new message handler may make damage to the performance and switch-case statement is easier to read for Windows message handler.

Before sending key messages to plugin's windowproc, we should check if the key combination is reserved by chrome. If a key combination is consumed by reserved command in the parent process, we should not send it to the plugin. The sending message should not be raw WM_(SYS)KEY(DOWN|UP) because if we send it to the parent process, parent process will call ::TranslateMessage() and the key event may be handled by IME or may cause WM_(SYS)CHAR in the parent process. Therefore, this patch defines MOZ_WM_KEYDOWN and MOZ_WM_KEYUP. Note that sending message to the parent process may make damage to text input on plugins. Therefore, this is performed only when at least one modifier key except Shift key is pressed. For sharing our defining messages in all message handlers, this patch creates a new header file which just defines messages.

Only on Windows, when at least one modifier key except Shift key is pressed, each key event is sent to the parent process from a plugin process before sending the key event to the focused plugin. At this time, parent process needs to check if the key combination is reserved by chrome and if it's reserved, perform the command. For performing this without changes in normal keyboard event path, this patch defines new keyboard events, ePluginKeyDown and ePluginKeyUp. nsXBLWindowKeyHandler should listen to them and handle them as eKeyDown or eKeyUp event. Finally, ePluginKeyDown should perform a keypress event handler if it's reserved because keypress event won't be fired.

nsWindow for Windows, NativeKey and KeyboardLayout should handle MOZ_WM_KEYDOWN and MOZ_WM_KEYUP like WM_(SYS)KEYDOWN and WM_(SYS)KEYUP. Dispatching event for them should be ePluginKeyDown and ePluginKeyUp since this guarantees that neither keydown nor keyup event handler can listen to this. If the event is consumed, return true to the sender (a plugin process). Otherwise, return false. Note that MOZ_WM_KEYDOWN shouldn't cause eKeyPress because ePluginKeyDown should be handled as a keypress event if the key combination matches with a reserved command and we need to return to the plugin process as soon as possible.

Then, if it's true, nsXBLWindowKeyHandler should perform matching keypress event handler with eKeyDown. This *might* be useful if we will stop dispatching keypress events completely for non-printable key events like "Enter", "Escape". Then, like Ctrl-Tab, nobody needs to listen to new pluginkeyevents. Even if you like this approach better, I'd like to do this after I fix all regressions of the series of related patches. I meant, I've already landed enough risky changes at once. So, putting off such risky implementation later. But if you think I should take this approach here, I'll rewrite the patch and part.4. Up to you, smaug.

MOZ_WM_KEYDOWN : MOZ_WM_KEYUP, This doesn't look safe for a couple reasons - 1) If the browser is in an ipc rpc or sync send, this will end up getting processed by our deferred handling code in WindowsMessageLoop.cpp. 2) If this gets processed in the browser, what does the browser do with this message? Could this generate gecko events? 3) In 64-bit builds this call will fail due to a bad hwnd.

Can we check if it's in IPC RPC (we can check if it's in SendMessage(), though)? Or should I use other way to send key messages to the chrome process, e.g., IPC? > 2) If this gets processed in the browser, what does the browser do with this > message? Could this generate gecko events? Yes, it generates new Gecko events. The events are handled only by nsXBLWindowKeyHandler for now. However, it's possible to listen them in web content if web developers know the event name. So, yes, I should change the following patch which won't expose the new event to the web contents. > 3) In 64-bit builds this call will fail due to a bad hwnd.

Looks like users cannot enable windowed mode if Flash is in sandbox: https://reviewboard.mozilla.org/r/21809/diff/2#index_header And I assume that sandbox is enabled only when the plugin is Flash. http://mxr.mozilla.org/mozilla-central/source/browser/app/profile/firefox.js?rev=b153d20c301d#1182 However, looks like that user can enable sandbox for Silverlight...
Okay, I'm rewriting the patches with using IPC instead of SendMessage(). However, I still have a question. That is, checking |(InSendMessageEx(nullptr)&(ISMEX_REPLIED|ISMEX_SEND)) == ISMEX_SEND| before IPC is enough for safe.

We need the complicated path for matching each key message with the keyboard layout. The main reason why I need to use synchronous communication between plugin process and chrome process is that key messages needs to be passed to ::TraslateMessage() API and plugin does it already. If we can steal key messages before that, we can post the key messages to chrome process and we can post back the key message again from EventStateManager like a default action. Is this possible?

Okay, I'm thinking another approach. That is, when PluginInstanceChild recevies WM_KEYDOWN/WM_KEYUP, it should send the messages to nsWindow with asynchronous IPC. Then, nsWindow dispatches eKeyDownOnPlugin/eKeyUpOnPlugin to execute reserved shortcut keys. After that, nsWindow should post MOZ_WM_KEYDOWN/MOZ_WM_KEYUP to the plugin window and PluginInstanceChild sends the key message to plugin. If PluginInstanceChild receives another WM_KEYDOWN/WM_KEYUP after posting MOZ_WM_KEYDOWN_ON_PLUGIN/MOZ_WM_KEYUP_ON_PLUGIN but not received MOZ_WM_KEYDOWN/MOZ_WM_KEYUP yet, whole key events should be handled in same path. Then, we can avoid to shuffle the order of key events on plugin. Of course, the performance may not good but I believe that it's rare case to type characters normally immediately after Ctrl+foo or Alt+foo.

New patches use neither synchronous IPC nor SendMessage(), i.e., fully asynchronus handling about shortcut key handling and following messages if it's necessary.
When PluginInstanceChild receives native key events, it should post the events to the chrome process first for checking if the key combination is reserved. However, posting all key events to the chrome process may make damage to the performance of text input. Therefore, this patch starts to post a key event whose key combination may be a shortcut key. However, for avoiding to shuffle the event order, it posts following key events until all posted key events are handled by the chrome process. For receiving response from widget, this patch defines nsIKeyEventInPluginCallback. It's specified by nsIWidget::OnKeyEventInPluginProcess() for ensuring the caller will receive the reply. Basically, the caller of nsIWidget::OnKeyEventInPluginProcess() should reply to the child process. However, if the widget is a PuppetWidget, it cannot return the result synchronously. Therefore, PuppetWidget::OnKeyEventInPluginProcess() returns NS_SUCCESS_EVENT_HANDLED_ASYNCHRONOUSLY and stores the callback to mKeyEventInPluginCallbacks. Then, TabParent::HandledKeyEventBeforePlugin() will call PuppetWidget::HandledKeyEventBeforePlugin().

On Windows, applications cannot handle IME messages asynchronously. Therefore, we cannot put off to send IME messages to plugin even if there are some pending keyboard events which were posted to the parent process. This patch makes PluginInstanceChild consume all key events which are returned from the parent process during IME composition. And when an IME composition is committed, mark pending key events as outdated.

If a plugin process posts native key events to the widget, it needs to check if the key combination is reserved by chrome because if it's reserved by chrome, the reserved shortcut key handler should be executed and the event shouldn't be handled by the focused plugin. This patches add eKeyDownOnPlugin and eKeyUpOnPlugin. nsXBLWindowKeyHandler will listen to them and handle them as normal keydown and keypress or keyup event. Note that these events won't be fired on content in the default event group and won't be sent to the remote process.

eKeyDownOnPlugin (mozkeydownonplugin) and eKeyUpOnPlugin (mozkeyuponplugin) should execute if the key combination is reserved by the linked <command> element. Note that there is no eKeyPressOnPlugin. Therefore, eKeyDownOnPlugin may execute shortcut key handler which is registered as a keypress event handler.

nsWindow for Windows cannot decide if a preceding WM_*KEYDOWN or WM_*KEYUP which is a preceding message of WM_*CHAR is consumed because nsWindow cannot know if WM_*CHAR message came from same window which received the preceding WM_*KEYDOWN or WM_*KEYUP.

I assume it is. I'm not sure what did you mean here. This bug isn't related to e10s vs. non-e10s. But perhaps, my patches work with only OOPP (IIRC, in process plugin has already gone completely). > I'm not sure I like that those methods hide the plugin-ness of the events, since I assume people > could easily start to use them elsewhere assuming they deal with normal events only. Yes. But in most cases, key events on plugin should be ignored since they should be handled only by some handlers which need to intercept key events before plugin like the reserved shortcut keys. > So could we call the methods something like > IsKeyOrPluginKeyDownEvent ? Same with other methods. Sure. The purpose of the methods are just for easier to read since without the methods, there were a lot of additional conditions such as |aMessage == eKeyDown || aMessage == eKeyDownOnPlugin || aMessage == eKeyUp || aMessage == eKeyUpOnPlugin|.

Which is exactly why I don't like the plugin-ness to be hidden. Otherwise we'll end up handling those events in cases we shouldn't.

Although, I don't like the behavior (I think that key events should be handled in system group or as default action (i.e., after all propagations)). > Do we end up changing that behavior with all these patches? No, this bug tries to fix only a specific issue of windowed mode on Windows. That is, in windowed mode on Windows, native key events are fired only in the plugin process. Therefore, currently, no keyboard events are fired when a windowed plugin has focus on Windows. However, we should execute at least reserved shortcut keys even on windowed plugins. Therefore, these patches post key events whose modifier state may match shortcut key (i.e., only when Ctrl or Alt is pressed) to the chrome process asynchronously (and receiving its result asynchronously). The reason why we don't post all key events to the chrome process is that it may make damage to the text input performance because at least 4 times, asynchronous IPCs are necessary per native key event (one key press causes at least 3 native key events on Windows). Additionally, IME on Windows needs to be handled by plugin *synchronously*. So, we cannot post key events if there is composition in the plugin or key events which may cause starting composition since we shouldn't shuffle event order at sending plugin. Due to those limitations, I'm trying to fix only reserved shortcut key issue on windowed plugin on Windows for now. In other words, these patches don't change any behavior on web contents since the new key events on plugin are never fired in the default event group on web contents. So, just creating a chance to execute reserved shortcut key handler before sending native key events to focused plugin.
Btw, I thought we were going to get rid of windowed plugins. But perhaps that isn't going to happen real soon.
> So this could still use a short comment why key event on plugin isn't handled here. Both plugin process and our chrome process have independent IME contexts. So, handling key events on plugins don't need to check our chrome process's composition state. I'll add a comment before landing.
(In reply to Olli Pettay [:smaug] from comment #75) > Btw, I thought we were going to get rid of windowed plugins. But perhaps > that isn't going to happen real soon. Yes. But it's only for Flash Player. I.e., if we'd put off to ban the other plugins (especially, Silverlight), we'd need this fix even after getting rid of windowed Flash Player.

This patch has done nothing at all. Shortcuts still don't work in flash. Explanation in bug 78414 comment 678 Personally for Masayuki Nakano: (In reply to Masayuki Nakano [:masayuki] (Mozilla Japan) (not in London) from bug 78414 comment 679) > Hey, I said, "If you think that it's not enough to reserve shortcut keys for > some functions, please file a bug for each shortcut key". > > And Ctrl+N, Ctrl+W and Ctrl+T should work on Windows. They are reserved shortcut keys. 1) You haven't seen me saying that I want some _additional_ shortcut to be "reserved", so there was no need to repeat an irrelevant phrase from another comment (which I pretty much read). Are you making these logical failures (including discussions in other bugs) on purpose??? 2) I said that NO SHORTCUTS work in flash, so bug 78414 is clearly not "fixed" in any way. You completely ignored that fact, so OK, I'll reopen this bug. There's no need to create more bugs for the same issue as there're plenty of duplicates filed. Including bug 78414, which is not fixed. 3) You completely ignored (I'm getting used to this) the fact that it's not clear which shortcuts as there's no obvious list in any bug you mentioned in bug 78414 comment 676, bug 78414 comment 677 If there was an list, that'd allowed all users to distinguish "request for a new reserved shortcut" from "mozilla failed to provide announced functionality". Well, _I_ was quite confident that actual bug 78414 is the latter case, but you somehow responded as if it was the latter case (and it is). If you ever made clear list of reserved shortcuts existed, there'd be no such confusion (probably).

Hey, don't reopen existing fixed bugs. Please file a new bug for specific bugs. At least on my environment, this fix really work fine.

arni2033: First, you should test in safe mode. Finally, but if you still reproduce a bug for reserved shortcut keys on Windows or Mac, please file a bug for each problem since they must be specific bugs depending on some environment or conditions.
> 1) You haven't seen me saying that I want some _additional_ shortcut to be "reserved" I've not talked only to you. You should read XUL reference and search reserved attribute in mozilla-central.
What about a link? I have the exact same question: What shortcut keys are "reserved", i.e. which shortcuts can I expect to always work even when a plugin is active. Please drop the arrogant attitude, since it's not helpful... Only because arni2033 raised his concerns in a too aggressive manner does not mean they are invalid.
