From 2190ea6c4e7f56f29fc18539284801a5f504ee48 Mon Sep 17 00:00:00 2001 From: "Wladimir J. van der Laan" Date: Fri, 18 Sep 2015 15:45:38 +0200 Subject: rpc: Split option -rpctimeout into -rpcservertimeout and -rpcclienttimeout The two timeouts for the server and client, are essentially different: - In the case of the server it should be a lower value to avoid clients clogging up connection slots - In the case of the client it should be a high value to accomedate slow responses from the server, for example for slow queries or when the lock is contended Split the options into `-rpcservertimeout` and `-rpcclienttimeout` with respective defaults of 30 and 900. --- src/bitcoin-cli.cpp | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src/bitcoin-cli.cpp') diff --git a/src/bitcoin-cli.cpp b/src/bitcoin-cli.cpp index 866c6f2d4..7839b3b6b 100644 --- a/src/bitcoin-cli.cpp +++ b/src/bitcoin-cli.cpp @@ -22,6 +22,8 @@ using namespace std; +static const int DEFAULT_HTTP_CLIENT_TIMEOUT=900; + std::string HelpMessageCli() { string strUsage; @@ -37,6 +39,7 @@ std::string HelpMessageCli() strUsage += HelpMessageOpt("-rpcwait", _("Wait for RPC server to start")); strUsage += HelpMessageOpt("-rpcuser=", _("Username for JSON-RPC connections")); strUsage += HelpMessageOpt("-rpcpassword=", _("Password for JSON-RPC connections")); + strUsage += HelpMessageOpt("-rpcclienttimeout=", strprintf(_("Timeout during HTTP requests (default: %d)"), DEFAULT_HTTP_CLIENT_TIMEOUT)); return strUsage; } @@ -150,7 +153,7 @@ UniValue CallRPC(const string& strMethod, const UniValue& params) struct evhttp_connection *evcon = evhttp_connection_base_new(base, NULL, host.c_str(), port); // TODO RAII if (evcon == NULL) throw runtime_error("create connection failed"); - evhttp_connection_set_timeout(evcon, GetArg("-rpctimeout", 30)); + evhttp_connection_set_timeout(evcon, GetArg("-rpcclienttimeout", DEFAULT_HTTP_CLIENT_TIMEOUT)); HTTPReply response; struct evhttp_request *req = evhttp_request_new(http_request_done, (void*)&response); // TODO RAII -- cgit v1.2.3
