If it has expired, +/// the caller also receives start, stop and count values for the +/// event which the application can then report in whatever manner +/// it sees fit. +/// * The timer becomes passive after an isExpired() call that returns +/// true.

All I/O is completed asynchronously in + another thread. But notifications are polled by calling update() + and invoking a handler for completed requests. + + In this example, the invocation also deletes the handler (which is + never referenced by the llcorehttp code again). But other + allocation models are possible including handlers shared by many + requests, stack-based handlers and handlers mixed in with other, + unrelated classes. + + LLCore::HttpRequest(). Instances of this class are used to request + all major functions of the library. Initialization, starting + requests, delivering final notification of completion and various + utility operations are all done via instances. There is one very + important rule for instances: + + Request objects may NOT be shared between threads. + + my_priority. The APIs support the idea of priority ordering of + requests but it hasn't been implemented and the hope is that this + will become useless and removed from the interface. Use 0U except + as noted. + + my_policy. This is an important one. This library attempts to + manage TCP connection usage more rigorously than in the past. This + is done by issuing requests to a queue that has various settable + properties. These establish connection usage for the queue as well + as how queues compete with one another. (This is patterned after + class-based queueing used in various networking stacks.) Several + classes are pre-defined. Deciding when to use an existing class and + when to create a new one will determine what kind of experience + users have. We'll pick up this question in detail below. + + requestGet(). Issues an ordinary HTTP GET request to a given URL + and associating the request with a policy class, a priority and an + response handler. Two additional arguments, not used here, allow + for additional headers on the request and for per-request options. + If successful, the call returns a handle whose value is other than + LLCORE_HTTP_HANDLE_INVALID. The HTTP operation is then performed + asynchronously by another thread without any additional work by the + caller. If the handle returned is invalid, you can get the status + code by calling my_request->getStatus(). + + update(). To get notification that the request has completed, a + call to update() will invoke onCompleted() methods. + + +3. Refinements, Necessary and Otherwise + + MyHandler::onCompleted(). You'll want to do something useful with + your response. Distinguish errors from successes and getting the + response body back in some form. + + Add a new header: + + + #include "bufferarray.h" + + + Replace the existing MyHandler::onCompleted() definition with: + + + virtual void onCompleted(LLCore::HttpHandle /* handle */, + LLCore::HttpResponse * response) + { + LLCore::HttpStatus status = response->getStatus(); + if (status) + { + // Successful request.

The header file "httprequest.h" documents the expected + important headers that will go out with the request. You can add to + these by including an HttpHeaders object with the requestGet() call. + These are typically setup once as part of init rather than + dynamically created. + + Add another header: + + + #include "httpheaders.h" + + + In LLAppViewer::mainLoop(), add this alongside the allocation of + my_handler: + + + // Additional headers for all requests + LLCore::HttpHeaders * my_headers = new LLCore::HttpHeaders(); + my_headers->append("Accept", "text/html, application/llsd+xml"); + + + HttpOptions. Options are similar and include a mix of value types. + One interesting per-request option is the trace setting. This + enables various debug-type messages in the log file that show the + progress of the request through the library. It takes values from + zero to three with higher values giving more verbose logging. We'll + use '2' and this will also give us a chance to verify that + HttpHeaders works as expected. + + Same as above, a new header: + + + #include "httpoptions.h" + + + And in LLAppView::mainLoop(): + + + // Special options for requests + LLCore::HttpOptions * my_options = new LLCore::HttpOptions(); + my_options->setTrace(2); + + + Now let's put that all together into a more complete requesting + sequence.

What Does All That Mean, Part 2 + + HttpStatus. The HttpStatus object encodes errors from libcurl, the + library itself and HTTP status values. It does this to avoid + collapsing all non-HTTP error into a single '499' HTTP status and to + make errors distinct. + + To aid programming, the usual bool conversions are available so that + you can write 'if (status)' and the expected thing will happen + whether it's an HTTP, libcurl or library error. There's also + provision to override the treatment of HTTP errors (making 404 a + success, say). + + Share data, don't copy it. The library was started with the goal of + avoiding data copies as much as possible. Instead, read-only data + sharing across threads with atomic reference counts is used for a + number of data types. These currently are: + + * BufferArray. Linked list of data blocks/HTTP bodies. + * HttpHeaders. Shared headers for both requests and responses. + * HttpOptions. Request-only data modifying HTTP behavior. + * HttpResponse. HTTP response description given to onCompleted. + + Using objects of these types requires a few rules: + + * Constructor always gives a reference to caller. + * References are dropped with release() not delete. + * Additional references may be taken out with addRef(). + * Unless otherwise stated, once an object is shared with another + thread it should be treated as read-only. There's no + synchronization on the objects themselves. + + HttpResponse. You'll encounter this mainly in onCompleted() methods. + Commonly-used interfaces on this object: + + * getStatus() to return the final status of the request. + * getBody() to retrieve the response body which may be NULL or + zero-length. + * getContentType() to return the value of the 'Content-Type' + header or an empty string if none was sent. + + This is a reference-counted object so you can call addRef() on it + and hold onto the response for an arbitrary time. But you'll + usually just call a few methods and return from onCompleted() whose + caller will release the object. + + BufferArray. The core data representation for request and response + bodies. In HTTP responses, it's fetched with the getBody() method + and may be NULL or non-NULL with zero length. All successful data + handling should check both conditions before attempting to fetch + data from the object. Data access model uses simple read/write + semantics: + + * append() + * size() + * read() + * write() + + (There is a more sophisticated stream adapter that extends these + methods and will be covered below.) So, one way to retrieve data + from a request is as follows: + + + LLCore::BufferArray * data = response->getBody(); + if (data && data->size()) + { + size_t data_len = data->size(); + char * data_blob = new char [data_len + 1]; + data->read(0, data_blob, data_len); + + + HttpOptions and HttpResponse. Really just simple containers of POD + and std::string pairs. But reference counted and the rule about not + modifying after sharing must be followed. You'll have the urge to + change options dynamically at some point. And you'll try to do that + by just writing new values to the shared object. And in tests + everything will appear to work. Then you ship and people in the + real world start hitting read/write races in strings and then crash. + Don't be lazy. + + HttpHandle. Uniquely identifies a request and can be used to + identify it in an onCompleted() method or cancel it if it's still + queued. But as soon as a request's onCompleted() invocation + returns, the handle becomes invalid and may be reused immediately + for new requests. Don't hold on to handles after notification. + + +5. And Still More Refinements + + (Note: The following refinements are just code fragments. They + don't directly fit into the working example above. But they + demonstrate several idioms you'll want to copy.) + + LLSD, std::streambuf, std::iostream. The read(), write() and + append() methods may be adequate for your purposes. But we use a + lot of LLSD. Its interfaces aren't particularly compatible with + BufferArray. And so two adapters are available to give + stream-like behaviors: BufferArrayStreamBuf and BufferArrayStream, + which implement the std::streambuf and std::iostream interfaces, + respectively. + + A std::streambuf interface isn't something you'll want to use + directly. Instead, you'll use the much friendlier std::iostream + interface found in BufferArrayStream. This adapter gives you all + the '>>' and '<<' operators you'll want as well as working + directly with the LLSD conversion operators. + + Some new headers: + + + #include "bufferstream.h" + #include "llsdserialize.h" + + + And an updated fragment based on onCompleted() above: + + + // Successful request. Try to fetch the data + LLCore::BufferArray * data = response->getBody(); + LLSD resp_llsd; + + if (data && data->size()) + { + // There's some data and we expect this to be + // LLSD. Checking of content type and validation + // during parsing would be admirable additions. + // But we'll forgo that now. + LLCore::BufferArrayStream data_stream(data); + LLSDSerialize::fromXML(resp_llsd, data_stream); + } + LL_INFOS("Hack") << "LLSD Received: " << resp_llsd << LL_ENDL; + } + else + { + + + Converting an LLSD object into an XML stream stored in a + BufferArray is just the reverse of the above: + + + BufferArray * data = new BufferArray(); + LLCore::BufferArrayStream data_stream(data); + + LLSD src_llsd; + src_llsd["foo"] = "bar"; + + LLSDSerialize::toXML(src_llsd, data_stream); + + // 'data' now contains an XML payload and can be sent + // to a web service using the requestPut() or requestPost() + // methods. + ... requestPost(...); + + // And don't forget to release the BufferArray. + data->release(); + data = NULL; + + + LLSD will often go hand-in-hand with BufferArray and data + transport. But you can also do all the streaming I/O you'd expect + of a std::iostream object: + + + BufferArray * data = new BufferArray(); + LLCore::BufferArrayStream data_stream(data); + + data_stream << "Hello, World!" << 29.4 << '\n'; + std::string str; + data_stream >> str; + std::cout << str << std::endl; + + data->release(); + // Actual delete will occur when 'data_stream' + // falls out of scope and is destructed. + + + Scoping objects and cleaning up. The examples haven't bothered + with cleanup of objects that are no longer needed. Instead, most + objects have been allocated as if they were global and eternal. + You'll put the objects in more appropriate feature objects and + clean them up as a group. Here's a checklist for actions you may + need to take on cleanup: + + * Call delete on: + o HttpHandlers created on the heap + o HttpRequest objects + * Call release() on: + o BufferArray objects + o HttpHeaders objects + o HttpOptions objects + o HttpResponse objects + + On program exit, as threads wind down, the library continues to + operate safely. Threads don't interact via the library and even + dangling references to HttpHandler objects are safe. If you don't + call HttpRequest::update(), handler references are never + dereferenced. + + You can take a more thorough approach to wind-down. Keep a list + of HttpHandles (not HttpHandlers) of outstanding requests. For + each of these, call HttpRequest::requestCancel() to cancel the + operation. (Don't add the cancel requests' handled to the list.) + This will cancel the outstanding requests that haven't completed. + Canceled or completed, all requests will queue notifications. You + can now cycle calling update() discarding responses. Continue + until all requests notify or a few seconds have passed. + + Global startup and shutdown is handled in the viewer. But you can + learn about it in the code or in the documentation in the headers. + + +6. Choosing a Policy Class + + Now it's time to get rid of the default policy class. Take a look + at the policy class definitions in newview/llappcorehttp.h. + Ideally, you'll find one that's compatible with what you're doing. + Some of the compatibility guidelines are: + + * Destination: Pair of host and port. Mixing requests with + different destinations may cause more connection setup and tear + down. + + * Method: http or https. Usually moot given destination. But + mixing these may also cause connection churn. + + * Transfer size: If you're moving 100MB at a time and you make your + requests to the same policy class as a lot of small, fast event + information that fast traffic is going to get stuck behind you + and someone's experience is going to be miserable. + + * Long poll requests: These are long-lived, must- do operations. + They have a special home called AP_LONG_POLL. + + * Concurrency: High concurrency (5 or more) and large transfer + sizes are incompatible. Another head-of-the-line problem. High + concurrency is tolerated when it's desired to get maximal + throughput. Mesh and texture downloads, for example. + + * Pipelined: If your requests are not idempotent, stay away from + anything marked 'soon' or 'yes'. Hidden retries may be a + problem for you. For now, would also recommend keeping PUT and + POST requests out of classes that may be pipelined. Support for + that is still a bit new. + + If you haven't found a compatible match, you can either create a + new class (llappcorehttp.*) or just use AP_DEFAULT, the catchall + class when all else fails. Inventory query operations might be a + candidate for a new class that supported pipelining on https:. + Same with display name lookups and other bursty-at-login + operations. For other things, AP_DEFAULT will do what it can and + will, in some way or another, tolerate any usage. Whether the + users' experiences are good are for you to determine. + + +7. FAQ + + Q1. What do these policy classes achieve? + + A1. Previously, HTTP-using code in the viewer was written as if + it were some isolated, local operation that didn't have to + consider resources, contention or impact on services and the + larger environment. The result was an application with on the + order of 100 HTTP launch points in its codebase that could create + dozens or even 100's of TCP connections zeroing in on grid + services and disrupting networking equipment, web services and + innocent users. The use of policy classes (modeled on + http://en.wikipedia.org/wiki/Class-based_queueing) is a means to + restrict connection concurrency, good and necessary in itself. In + turn, that reduces demands on an expensive resource (connection + setup and concurrency) which relieves strain on network points. + That enables connection keepalive and opportunites for true + improvements in throughput and user experience. + + Another aspect of the classes is that they give some control over + how competing demands for the network will be apportioned. If + mesh fetches, texture fetches and inventory queries are all being + made at once, the relative weights of their classes' concurrency + limits established that apportioning. We now have an opportunity + to balance the entire viewer system. + + Q2. How's that data sharing with refcounts working for you? + + A2. Meh. It does reduce memory churn and the frequency at which + free blocks must be moved between threads. But it's also a design + for static configuration and dynamic reconfiguration (not + requiring a restart) is favored. Creating new options for every + request isn't too bad, it a sequence of "new, fill, request, + release" for each requested operation. That in contrast to doing + the "new, fill, release" at startup. The bad comes in getting at + the source data. One rule in this work was "no new thread + problems." And one source for those is pulling setting values out + of gSettings in threads. None of that is thread safe though we + tend to get away with it. + + Q3. What needs to be done? + + A3. There's a To-Do list in _httpinternal.h. It has both large + and small projects here if someone would like to try changes. diff --git a/indra/llcorehttp/_httpinternal.h b/indra/llcorehttp/_httpinternal.h index 008e4fd95c..f80d7f60f5 100755 --- a/indra/llcorehttp/_httpinternal.h +++ b/indra/llcorehttp/_httpinternal.h @@ -4,7 +4,7 @@ * * $LicenseInfo:firstyear=2012&license=viewerlgpl$ * Second Life Viewer Source Code - * Copyright (C) 2012, Linden Research, Inc. + * Copyright (C) 2012-2013, Linden Research, Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -36,7 +36,8 @@ // General library to-do list // // - Implement policy classes.
