EOS 部署合约出现 deadline ? exceeded by ?us
测试环境
OS: Ubuntu 18.04 server
EOS: v2.0.1
合约:v1.9.1
部署系统合约时出现以下错误
error 2020-02-07T03:05:55.178 cleos main.cpp:4042 main ] Failed with error: deadline 2020-02-07T03:05:55.175 exceeded by 43us (2)
deadline 2020-02-07T03:05:55.175 exceeded by 43us
跟下代码(跳转github)
#define FC_CHECK_DEADLINE( DEADLINE, ... ) \
FC_MULTILINE_MACRO_BEGIN \
if( DEADLINE < fc::time_point::maximum() && DEADLINE < fc::time_point::now() ) { \
auto log_mgs = FC_LOG_MESSAGE( error, "deadline ${d} exceeded by ${t}us ", \
FC_FORMAT_ARG_PARAMS(__VA_ARGS__)("d", DEADLINE)("t", fc::time_point::now() - DEADLINE) ); \
auto msg = log_mgs.get_limited_message(); \
throw timeout_exception( std::move( log_mgs ), timeout_exception_code, "timeout_exception", std::move( msg ) ); \
} \
FC_MULTILINE_MACRO_END
跟踪宏的调用 (跳转github)
string exception::to_string( log_level ll )const
{
const auto deadline = fc::time_point::now() + format_time_limit;
std::stringstream ss;
try {
ss << my->_what;
try {
ss << " (" << variant( my->_code ).as_string() << ")\n";
} catch( std::bad_alloc& ) {
throw;
} catch( ... ) {
ss << "<- exception in to_string.\n";
}
for( auto itr = my->_elog.begin(); itr != my->_elog.end(); ++itr ) {
try {
FC_CHECK_DEADLINE(deadline);
查看 main.cpp:4042
(跳转github)
if (!print_recognized_errors(e, verbose)) {
// Error is not recognized
if (!print_help_text(e) || verbose) {
elog("Failed with error: ${e}", ("e", verbose ? e.to_detail_string() : e.to_string()));
}
}
发现该异常,为解析异常错误导致的解析超时错误,并非当时真实的错误。

2.0和1.8.9包括新的选项http-max-response-time-ms,该选项有助于减轻api节点的滥用。它允许您指定处理请求的时间限制。当前,这意味着将响应转换为json所需的时间受到限制,这是大多数api请求中最耗时的部分。我们将默认值设为30毫秒,以匹配默认的max-transaction-time。对于大块,30ms可能不足以让您的节点转换为json。当然取决于硬件等。随时随地将它放置在任何级别,您可以满足任何一个处理请求的要求。
解决方法
将http-max-response-time-ms
参数修改为30毫秒
http-max-response-time-ms = 30
