2010-08-13Change license from GPL to LGPL (version 2.1)Oz Linden
2010-04-30Looks like the linux apr version is a bit too old to build 5458d58b4cd0. ↵Tofu Linden
Use this workaround for now.
2010-04-29Incorporate suggestions from Richard's review of the LLPlugin changes.Monroe Linden
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().
2010-04-27Architectural changes to LLPlugin message processing.Monroe Linden
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().
2010-04-23Add a way for plugins to send a message and block waiting for the responseMonroe Linden
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.
2010-03-16Added an "init" message in LLPLUGIN_MESSAGE_CLASS_MEDIA, and made ↵Monroe Linden
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. Reviewed by Callum at http://codereview.lindenlab.com/687006 .

tree (mostly media stuff) propagate the parent app's OSUserAppDir (i.e. ~/.secondlife/) all the way down to plugins, if they need persistant user data/settings (like the webkit plugin needs a place to put its cache).

2009-11-10Added PluginAttachDebuggerToPlugins debug setting.Monroe Linden
Added accessors to get platform-specific process ID from LLProcessLauncher. Added an optional "debug" argument to LLPluginClassMedia::init() and LLPluginProcessParent::init() (defaults to false). Mac only: made the state machine in LLPluginProcessParent::idle() open a new window in Terminal.app with a gdb session attached to the plugin process upon successful launch.
2009-10-26Potential fix for https://jira.lindenlab.com/jira/browse/DEV-41702callum
and https://jira.lindenlab.com/jira/browse/DEV-38579. Both relate to media not working properly and were likely caused by an uninitialized heartbeat timeout.
2009-10-08Log the plugin version string when a plugin is loaded.Monroe Linden
2009-10-05Fixes for a different class of plugin failures (where loading the plugin dll ↵Monroe Linden
fails) causing an error message loop: Made LLPluginProcessParent differentiate between failures launching/loading the plugin and failures after the plugin has been loaded. This allows us to handle launch failures differently, since retrying is unlikely to fix them. Added new media event MEDIA_EVENT_PLUGIN_FAILED_LAUNCH to indicate a launch failure. Added a case for the new event to LLViewerMediaImpl::handleMediaEvent() that sets the "failed init" flag to prevent retries.
