Use LLMutexLock (stack-based locker/unlocker) for the straightforward cases instead of explicit lock()/unlock().
There are still a couple of cases (one overlapping lock lifetime and two loops that unlock the mutex to call another function inside the loop) where I'm leaving explicit lock/unlock calls.
Rename LLPluginProcessParent::sPollThread to sReadThread, for consistency.
Made the LLPluginProcessParent destructor hold mIncomingQueueMutex while removing the instance from the global list -- this should prevent a possible race condition in LLPluginProcessParent::poll().
Removed a redundant check when calling LLPluginProcessParent::setUseReadThread().

events to blocked plugins.

LLPluginProcessParent can now optionally use a separate thread for reading messages from plugin sockets. If this is enabled, it will spawn a single thread and use apr_pollset_poll to wake up the thread when incoming data arrives instead of polling all the descriptors round-robin every frame. This should be somewhat more efficient, and should also allow blocking requests from plugins to be serviced much more quickly (once we start using them). This is currently disabled by default, until it's had a bit more focused testing on multiple platforms.
Hooked up the switch to use the message read thread to the PluginUseReadThread debug setting and an item in the Advanced menu in the viewer, and to a checkbox in the UI in llmediaplugintest.
Updated some debug logging in the plugin system to have appropriate tags and not log dire-looking warnings during normal operation.
LLPluginProcessParent now once again explicitly kills plugin processes (instead of just closing their sockets and waiting for them to exit). The problem we were attempting to solve by not doing the kill (letting the webkit plugin write its cookie file on exit) has been solved another way.
LLPluginProcessParent::sendMessage() now attempts to write the outgoing message to the socket immediately instead of waiting for the next frame. This should reduce the latency of sending plugin messages.
Added a separate fast timer for LLViewerMedia::updateMedia().

WaitNextEvent() for the OS X 10.6 SDK
Replaced the deprecated WaitNextEvent() call with ReceiveNextEvent() and SendEventToEventTarget() as a basic event loop in slplugin.cpp
|

This requires some cooperation between the plugin and the host, and will only work for specific messages.
The way it works is as follows:
* the plugin sends a message containing the key "blocking_request" (with any value)
* this will cause the "send message" function to block (continuing to pull incoming messages off the network socket and queue them) until it receives a message from the host containing the key "blocking_response"
** NOTE: if the plugin sends a blocking_request that isn't set up to cause the host to send back a blocking_response, it will block forever
* the blocking_response message will be handed to the plugin's "receive message" function _immediately_ (before the "send message" function returns)
** this means that the plugin can extract response data for use by the the code that sent the message (but is still blocked inside the "send message" call)
** NOTE: this BREAKS the invariant stating that the plugin's "receive message" function will never be called recursively, and the plugin MUST be prepared to deal with this
* after the plugin finishes processing the blocking_response message, the "send message" function that was called with the blocking_request message will return to the plugin
* any queued messages will be delivered after the outer invocation of the plugin's "receive message" function returns (as normal)
Inside the viewer, the code can tell when a plugin is in this blocked state by calling LLPluginProcessParent::isBlocked(). LLPluginClassMedia uses this to avoid sending mouse-move and size-change messages to blocked plugins.

in front)
Made SLPlugin into a bundled app on the Mac (this is apparently necessary for the plugin's window to be allowed to get focus).
Changed the Info.plist key SLPlugin uses to keep itself out of the dock from LSBackgroundOnly to LSUIElement (this allows it to get focus and display UI).
Added some Mac-specific code to slplugin.cpp to manipulate window layers and bring the plugin process to the foreground when something in the process opens a window, and to bring the viewer to the foreground when the last window in the process is closed.

Added "HttpOnly" to the allowed field names in LLPluginCookieStore::Cookie::parse(). (This was the actual cause of the failure -- cookies with this field in them were silently failing to parse.)
Added some LL_WARNS logging on this sort of cookie parse failure, which will make similar problems much easier to track down in future.
Also added tags to most of the logging in llplugincookiestore.cpp to make it easier to selectively enable it when debugging.
Added a cookie with all allowable field names to the unit test.

Extract openid_url and openid_token tokens from the login response in process_login_success_response() and send them to LLViewerMedia if they're present.
Added LLViewerMedia::openIDSetup() to receive openid_url and openid_token, and added code to LLViewerMedia to do a POST with LLHTTPClient, retrieve the resulting cookie, and push it into the central cookie store. Also made sure the OpenID cookie gets re-added when the cookie store is cleared.
Added LLPluginCookieStore::setCookiesFromHost() to properly add a cookie that may not have a domain set. Made LLPluginCookieStore::Cookie::parse() add missing domain and path fields to cookies as necessary.
Fixed an issue where carriage returns in the string passed to LLPluginCookieStore::setCookies() or LLPluginCookieStore::setCookiesFromHost() would cause a parse failure.

Added LLPluginCookieStore, which manages the central list of cookies.
New Mac and Windows versions of llqtwebkit, built from the tip of the cookie-api branch on http://bitbucket.org/lindenlab/llqtwebkit/ (currently revision f35a5eab8c2f).
Added "set_cookies" and "cookie_set" messages to the media_browser message class in the plugin API, and made the webkit plugin use them appropriately.
Added methods to LLViewerMedia to read/write the cookie file and add/remove individual cookies.
Added hooks to read/write the cookie file (plugin_cookies.txt) in the same places as the location history (idle_startup() in llstartup.cpp and LLAppViewer::cleanup(), respectively).

LLPluginClassMedia queue it up before initializing its LLPluginProcessParent.
Made all existing plugins send their texture_params message from this init message instead of the LLPLUGIN_MESSAGE_CLASS_BASE "init" message. (This ensures that they won't start to receive 'size_change' messages until after the init has happened.)
Added "set_user_data_path" and "set_language_code" messages to LLPluginClassMedia.
Made webkit plugin deal with the new messages, when they're sent before it receives the media "init".
Removed the user_data_path and language_code arguments from the init function calls throughout the hierarchy.
Made LLViewerMediaImpl queue up the language code and user data path messages before initializing the media.

Added an LLSD argument to LLPluginClassMedia::keyEvent() and LLPluginClassMedia::textInput() which contains the native key data.
Made LLViewerMediaImpl retrieve the native key data and pass it to keyEvent and textInput.
Added a native_key_data parameter to the text_event and key_event messages.
Made the webkit plugin extract the native_key_data parameter and pass it to the internal keyEvent() and unicodeInput() functions.
Fixed LLMediaPluginTest to match function signature change to LLPluginClassMedia::keyEvent().

Support href links in web views that have a target attribute set to
"_blank". This will open the link in the user's preferred browser

new llqtwebkit package that has just been pushed.
Also updated the hardcoded Qt version number in the About floater.

search/help windows. This should address EXT-4097.
Added a notion of "background color" to LLViewerMediaImpl and LLPluginClassMedia.
Added background color parameters to the size_change message.
Webkit plugin now sets the background color of the instance from the supplied background color, and navigates to a data: url with that background color instead of about:blank as its initial navigate.
Webkit plugin now no longer waits for the first onPageChanged event
LLViewerMediaImpl now clears the texture to the background color when initializing it.
Made LLMediaCtrl fill with its opaque background color when the media impl isn't set up yet.
Removed the initial data URL from the search and help floaters, since what it was doing is now handled internally by the new background color code.

Enabled CPU limit setting by default (set to 100% of 1 CPU).
Lowered default limits on plugin priorities: 2 normal+, 4 low, 8 total.
Limit on total number of instances now only applies to inworld media -- media instances in the UI (such as the help browser and search) don't count toward the limit. UI media will still bump inworld media down from normal/low priority, though.
Several improvements to plugin manager debug code in the nearby media list.
Don't load unloaded instances that are at PRIORITY_SLIDESHOW or PRIORITY_HIDDEN (they don't get unloaded, they just won't be loaded unless they're at higher priority).
Added LLViewerMediaImpl::isPlayable(), which indicates whether an instance would be loaded if it were high enough in the priority list (taking into account autoplay and current load state). Priority algorithm now takes this into account.
Fixed a couple of issues with approximate texture interest calculation and its use in setting priorities.
Adjusted sleep times on low and normal priorities to be more friendly.
