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/llfloaterscriptlimits.cpp | 63 +++++++++++++++++++++++---------- 1 file changed, 45 insertions(+), 18 deletions(-) (limited to 'indra/newview/llfloaterscriptlimits.cpp') diff --git a/indra/newview/llfloaterscriptlimits.cpp b/indra/newview/llfloaterscriptlimits.cpp index 17c34f1da0..7e94784751 100644 --- a/indra/newview/llfloaterscriptlimits.cpp +++ b/indra/newview/llfloaterscriptlimits.cpp @@ -183,8 +183,14 @@ void LLPanelScriptLimitsInfo::updateChild(LLUICtrl* child_ctr) // Responders ///---------------------------------------------------------------------------- -void fetchScriptLimitsRegionInfoResponder::result(const LLSD& content) +void fetchScriptLimitsRegionInfoResponder::httpSuccess() { + const LLSD& content = getContent();
