The SafeRunnable added the op to pendingAddOps, and runs the op. If an add op error unrecoverably, all operations after the failed operation are failed by the ledger handle, see errorOutPendingAdds. -Ivan On 23 December 2011 09:12, Dongdong Guo < [email protected] > wrote: I saw the source code， but i can not find the place where bookkeeper add entries in order, could you tell me where ? thanks ----- 原始邮件 ----- 发件人: "Ivan Kelly" < [email protected] > 收件人: [email protected] 发送时间: 星期四, 2011年 12 月 22日 下午 7:35:11 主题: Re: Question about "asyncAddEntry" On Thu, Dec 22, 2011 at 07:25:40PM +0800, Dongdong Guo wrote: > I use the "asyncAddEntry" and add lots of data, then wait finished, if the > first entry failed, is it possible that the subsequence entry success No, bookkeeper will add entries in order. If an add op fails completely, then all subsequent add ops will be errored, and the ledger will be forced to close. -Ivan
