From 6b3bb3d9bae730d26ddd561b93efc667f5c8d499 Mon Sep 17 00:00:00 2001 From: Gregory Maxwell Date: Sun, 25 Dec 2016 20:19:40 +0000 Subject: Change LogAcceptCategory to use uint32_t rather than sets of strings. This changes the logging categories to boolean flags instead of strings. This simplifies the acceptance testing by avoiding accessing a scoped static thread local pointer to a thread local set of strings. It eliminates the only use of boost::thread_specific_ptr outside of lockorder debugging. This change allows log entries to be directed to multiple categories and makes it easy to change the logging flags at runtime (e.g. via an RPC, though that isn't done by this commit.) It also eliminates the fDebug global. Configuration of unknown logging categories now produces a warning. --- src/httpserver.cpp | 37 +++++++++++++++++++------------------ 1 file changed, 19 insertions(+), 18 deletions(-) (limited to 'src/httpserver.cpp') diff --git a/src/httpserver.cpp b/src/httpserver.cpp index 799de1c2c..347433eb1 100644 --- a/src/httpserver.cpp +++ b/src/httpserver.cpp @@ -213,7 +213,7 @@ static bool InitHTTPAllowList() std::string strAllowed; for (const CSubNet& subnet : rpc_allow_subnets) strAllowed += subnet.ToString() + " "; - LogPrint("http", "Allowing HTTP connections from: %s\n", strAllowed); + LogPrint(BCLog::HTTP, "Allowing HTTP connections from: %s\n", strAllowed); return true; } @@ -243,7 +243,7 @@ static void http_request_cb(struct evhttp_request* req, void* arg) { std::unique_ptr hreq(new HTTPRequest(req)); - LogPrint("http", "Received a %s request for %s from %s\n", + LogPrint(BCLog::HTTP, "Received a %s request for %s from %s\n", RequestMethodString(hreq->GetRequestMethod()), hreq->GetURI(), hreq->GetPeer().ToString()); // Early address-based allow check @@ -293,7 +293,7 @@ static void http_request_cb(struct evhttp_request* req, void* arg) /** Callback to reject HTTP requests after shutdown. */ static void http_reject_request_cb(struct evhttp_request* req, void*) { - LogPrint("http", "Rejecting request while shutting down\n"); + LogPrint(BCLog::HTTP, "Rejecting request while shutting down\n"); evhttp_send_error(req, HTTP_SERVUNAVAIL, NULL); } @@ -301,10 +301,10 @@ static void http_reject_request_cb(struct evhttp_request* req, void*) static bool ThreadHTTP(struct event_base* base, struct evhttp* http) { RenameThread("bitcoin-http"); - LogPrint("http", "Entering http event loop\n"); + LogPrint(BCLog::HTTP, "Entering http event loop\n"); event_base_dispatch(base); // Event loop will be interrupted by InterruptHTTPServer() - LogPrint("http", "Exited http event loop\n"); + LogPrint(BCLog::HTTP, "Exited http event loop\n"); return event_base_got_break(base) == 0; } @@ -336,7 +336,7 @@ static bool HTTPBindAddresses(struct evhttp* http) // Bind addresses for (std::vector >::iterator i = endpoints.begin(); i != endpoints.end(); ++i) { - LogPrint("http", "Binding RPC on address %s port %i\n", i->first, i->second); + LogPrint(BCLog::HTTP, "Binding RPC on address %s port %i\n", i->first, i->second); evhttp_bound_socket *bind_handle = evhttp_bind_socket_with_handle(http, i->first.empty() ?
