From f945415210f0e18c2c6d941fda6b7d45cb0f06f1 Mon Sep 17 00:00:00 2001 From: Don Kjer Date: Wed, 13 Mar 2013 06:26:25 +0000 Subject: Large changes to the LLCurl::Responder API, as well as pulling in some changes to common libraries from the server codebase: * Additional error checking in http handlers. * Uniform log spam for http errors. * Switch to using constants for http heads and status codes. * Fixed bugs in incorrectly checking if parsing LLSD xml resulted in an error. * Reduced spam regarding LLSD parsing errors in the default completedRaw http handler. It should not longer be necessary to short-circuit completedRaw to avoid spam. * Ported over a few bug fixes from the server code. * Switch mode http status codes to use S32 instead of U32. * Ported LLSD::asStringRef from server code; avoids copying strings all over the place. * Ported server change to LLSD::asBinary; this always returns a reference now instead of copying the entire binary blob. * Ported server pretty notation format (and pretty binary format) to llsd serialization. * The new LLCurl::Responder API no longer has two error handlers to choose from. Overriding the following methods have been deprecated: ** error - use httpFailure ** errorWithContent - use httpFailure ** result - use httpSuccess ** completed - use httpCompleted ** completedHeader - no longer necessary; call getResponseHeaders() from a completion method to obtain these headers. * In order to 'catch' a completed http request, override one of these methods: ** httpSuccess - Called for any 2xx status code. ** httpFailure - Called for any non-2xx status code. ** httpComplete - Called for all status codes. Default implementation is to call either httpSuccess or httpFailure. * It is recommended to keep these methods protected/private in order to avoid triggering of these methods without using a 'push' method (see below). * Uniform error handling should followed whenever possible by calling a variant of this during httpFailure: ** llwarns << dumpResponse() << llendl; * Be sure to include LOG_CLASS(your_class_name) in your class in order for the log entry to give more context. * In order to 'push' a result into the responder, you should no longer call error, errorWithContent, result, or completed. * Nor should you directly call httpSuccess/Failure/Completed (unless passing a message up to a parent class). * Instead, you can set the internal content of a responder and trigger a corresponding method using the following methods: ** successResult - Sets results and calls httpSuccess ** failureResult - Sets results and calls httpFailure ** completedResult - Sets results and calls httpCompleted * To obtain information about a the response from a reponder method, use the following getters: ** getStatus - HTTP status code ** getReason - Reason string ** getContent - Content (Parsed body LLSD) ** getResponseHeaders - Response Headers (LLSD map) ** getHTTPMethod - HTTP method of the request ** getURL - URL of the request * It is still possible to override completeRaw if you want to manipulate data directly out of LLPumpIO. * See indra/llmessage/llcurl.h for more information. --- indra/newview/llviewerobjectlist.cpp | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) (limited to 'indra/newview/llviewerobjectlist.cpp') diff --git a/indra/newview/llviewerobjectlist.cpp b/indra/newview/llviewerobjectlist.cpp index 0561e731e7..576b801d5b 100644 --- a/indra/newview/llviewerobjectlist.cpp +++ b/indra/newview/llviewerobjectlist.cpp @@ -671,6 +671,7 @@ void LLViewerObjectList::updateApparentAngles(LLAgent &agent) class LLObjectCostResponder : public LLCurl::Responder { + LOG_CLASS(LLObjectCostResponder); public: LLObjectCostResponder(const LLSD& object_ids) : mObjectIDs(object_ids) @@ -691,20 +692,19 @@ public: } } - void errorWithContent(U32 statusNum, const std::string& reason, const LLSD& content) +private: + /* virtual */ void httpFailure() { - llwarns - << "Transport error requesting object cost " - << "[status: " << statusNum << "]: " - << content << llendl; + llwarns << dumpResponse() << llendl; // TODO*: Error message to user // For now just clear the request from the pending list clear_object_list_pending_requests(); } - void result(const LLSD& content) + /* virtual */ void httpSuccess() { + const LLSD& content = getContent(); if ( !content.isMap() || content.has("error") ) { // Improper response or the request had an error, @@ -760,6 +760,7 @@ private: class LLPhysicsFlagsResponder : public LLCurl::Responder { + LOG_CLASS(LLPhysicsFlagsResponder); public: LLPhysicsFlagsResponder(const LLSD& object_ids) : mObjectIDs(object_ids) @@ -780,20 +781,19 @@ public: } } - void errorWithContent(U32 statusNum, const std::string& reason, const LLSD& content) +private: + /* virtual */ void httpFailure() { - llwarns - << "Transport error requesting object physics flags " - << "[status: " << statusNum << "]: " - << content << llendl; + llwarns << dumpResponse() << llendl; // TODO*: Error message to user // For now just clear the request from the pending list clear_object_list_pending_requests(); } - void result(const LLSD& content) + /* virtual void */ void httpSuccess() { + const LLSD& content = getContent(); if ( !content.isMap() || content.has("error") ) { // Improper response or the request had an error, -- cgit v1.2.3
