It accepts requests to load textures // at a given priority and discard level and notifies the caller when done // (successfully or not). Additional constraints are: // // * Support a local texture cache. Don't hit network when possible // to avoid it. // * Use UDP or HTTP as directed or as fallback. HTTP is tried when // not disabled and a URL is available. UDP when a URL isn't // available or HTTP attempts fail. // * Asynchronous (using threads). Main thread is not to be blocked or // burdened. // * High concurrency. Many requests need to be in-flight and at various // stages of completion. // * Tolerate frequent re-prioritizations of requests. Priority is // a reflection of a camera's viewpoint and as that viewpoint changes, // objects and textures become more and less relevant and that is // expressed at this level by priority changes and request cancelations. // // The caller interfaces that fall out of the above and shape the // implementation are: // * createRequest - Load j2c image via UDP or HTTP at given discard level and priority // * deleteRequest - Request removal of prior request // * getRequestFinished - Test if request is finished returning data to caller // * updateRequestPriority - Change priority of existing request // * getFetchState - Retrieve progress on existing request // // Everything else in here is mostly plumbing, metrics and debug. // // // The Work Queue // // The two central classes are LLTextureFetch and LLTextureFetchWorker. // LLTextureFetch combines threading with a priority queue of work // requests. The priority queue is sorted by a U32 priority derived // from the F32 priority in the APIs. The *only* work request that // receives service time by this thread is the highest priority // request. All others wait until it is complete or a dynamic priority // change has re-ordered work. // // LLTextureFetchWorker implements the work request and is 1:1 with // texture fetch requests. Embedded in each is a state machine that // walks it through the cache, HTTP, UDP, image decode and retry // steps of texture acquisition. // // // Threads // // Several threads are actively invoking code in this module. They // include: // // 1. Tmain Main thread of execution // 2. Ttf LLTextureFetch's worker thread provided by LLQueuedThread // 3. Tcurl LLCurl's worker thread (should disappear over time) // 4. Ttc LLTextureCache's worker thread // 5. Tid Image decoder's worker thread // 6. Thl HTTP library's worker thread // // // Mutexes/Condition Variables // // 1. Mt Mutex defined for LLThread's condition variable (base class of // LLTextureFetch) // 2. Ct Condition variable for LLThread and used by lock/unlockData(). // 3. Mwtd Special LLWorkerThread mutex used for request deletion // operations (base class of LLTextureFetch) // 4. Mfq LLTextureFetch's mutex covering request and command queue // data. // 5. Mfnq LLTextureFetch's mutex covering udp and http request // queue data. // 6. Mwc Mutex covering LLWorkerClass's members (base class of // LLTextureFetchWorker). One per request. // 7. Mw LLTextureFetchWorker's mutex. One per request. // // // Lock Ordering Rules // // Not an exhaustive list but shows the order of lock acquisition // needed to prevent deadlocks. 'A < B' means acquire 'A' before // acquiring 'B'. // // 1. Mw < Mfnq // (there are many more...) // // // Method and Member Definitions // // With the above, we'll try to document what threads can call what // methods (using T* for any), what locks must be held on entry and // are taken out during execution and what data is covered by which // lock (if any). This latter category will be especially prone to // error so be skeptical. // // A line like: "// Locks: M<xxx>" indicates a method that must // be invoked by a caller holding the 'M<xxx>' lock. Similarly, // "// Threads: T<xxx>" means that a caller should be running in // the indicated thread. // // For data members, a trailing comment like "// M<xxx>" means that // the data member is covered by the specified lock. Absence of a // comment can mean the member is unlocked or that I didn't bother // to do the archaeology. In the case of LLTextureFetchWorker, // most data members added by the leaf class are actually covered // by the Mw lock. You may also see "// T<xxx>" which means that // the member's usage is restricted to one thread (except for // perhaps construction and destruction) and so explicit locking // isn't used. // // In code, a trailing comment like "// [-+]M<xxx>" indicates a // lock acquision or release point. // // // Worker Lifecycle // // The threading and responder model makes it very likely that // other components are holding on to a pointer to a worker request. // So, uncoordinated deletions of requests is a guarantee of memory // corruption in a short time. So destroying a request involves // invocations's of LLQueuedThread/LLWorkerThread's abort/stop // logic that removes workers and puts them ona delete queue for // 2-phase destruction. That second phase is deferrable by calls // to deleteOK() which only allow final destruction (via dtor) // once deleteOK has determined that the request is in a safe // state. // // // Worker State Machine // // (ASCII art needed) // // // Priority Scheme // // [PRIORITY_LOW, PRIORITY_NORMAL) - for WAIT_HTTP_RESOURCE state // and other wait states // [PRIORITY_HIGH, PRIORITY_URGENT) - External event delivered, // rapidly transitioning through states, // no waiting allowed // // By itself, the above work queue model would fail the concurrency // and liveness requirements of the interface. A high priority // request could find itself on the head and stalled for external // reasons (see VWR-28996). So a few additional constraints are // required to keep things running: // * Anything that can make forward progress must be kept at a // higher priority than anything that can't. // * On completion of external events, the associated request // needs to be elevated beyond the normal range to handle // any data delivery and release any external resource. // // This effort is made to keep higher-priority entities moving // forward in their state machines at every possible step of // processing. It's not entirely proven that this produces the // experiencial benefits promised. // ////////////////////////////////////////////////////////////////////////////// // Tuning/Parameterization Constants static const S32 HTTP_PIPE_REQUESTS_HIGH_WATER = 100; // Maximum requests to have active in HTTP (pipelined) static const S32 HTTP_PIPE_REQUESTS_LOW_WATER = 50; // Active level at which to refill static const S32 HTTP_NONPIPE_REQUESTS_HIGH_WATER = 40; static const S32 HTTP_NONPIPE_REQUESTS_LOW_WATER = 20; // BUG-3323/SH-4375 // *NOTE: This is a heuristic value.

So these are free-standing objects which are * managed in simple FIFO order on the mCommands queue of the * LLTextureFetch object. * * What each represents is a simple command sent from an * outside thread into the TextureFetch thread to be processed * in order and in a timely fashion (though not an absolute * higher priority than other operations of the thread). * Each operation derives a new class from the base customizing * members, constructors and the doWork() method to effect * the command. * * The flow is one-directional. There are two global instances * of the LLViewerAssetStats collector, one for the main program's * thread pointed to by gViewerAssetStatsMain and one for the * TextureFetch thread pointed to by gViewerAssetStatsThread1. * Common operations has each thread recording metrics events * into the respective collector unconcerned with locking and * the state of any other thread. But when the agent moves into * a different region or the metrics timer expires and a report * needs to be sent back to the grid, messaging across threads * is required to distribute data and perform global actions. * In pseudo-UML, it looks like: * * @verbatim * Main Thread1 * . . * . . * +-----+ . * | AM | . * +--+--+ . * +-------+ | . * | Main | +--+--+ . * | | | SRE |---. . * | Stats | +-----+ \ . * | | | \ (uuid) +-----+ * | Coll. | +--+--+ `-------->| SR | * +-------+ | MSC | +--+--+ * | ^ +-----+ | * | | (uuid) / . +-----+ (uuid) * | `--------' . | MSC |---------. * | . +-----+ | * | +-----+ . v * | | TE | . +-------+ * | +--+--+ . | Thd1 | * | | . | | * | +-----+ . | Stats | * `--------->| RSC | . | | * +--+--+ . | Coll. | * | . +-------+ * +--+--+ . | * | SME |---. . | * +-----+ \ . | * . \ (clone) +-----+ | * . `-------->| SM | | * . +--+--+ | * . | | * . +-----+ | * . | RSC |<--------' * . +-----+ * . | * . +-----+ * . | CP |--> HTTP POST * . +-----+ * . . * . . * * Key: * * SRE - Set Region Enqueued.
