如果refs / heads

Question

有很多关于做“git push＆＃39;在大型存储库中，您会收到如下错误：

the remote end hung up unexpectedly.

发生这种情况有几个原因，但在我的情况下，我通过让ssh发送一个空包来保持ssh连接存活来阻止它发生。我把它添加到〜/ .ssh / config：

Host *
 ServerAliveInterval 30
 ServerAliveCountMax 4

这样就可以阻止那个远程端挂起来了＃39;错误，但我看到发生的事情是git只是永远坐在那里。

如果我对正在运行的git进程执行pstack：

#13 lock_ref_for_update (err=0x7ffde40f2530, affected_refnames=0x7ffde40f23b0, head_ref=0xc979c0 "refs/heads/master", transaction=0xdd1ef0, update=0x1096e10, refs=0xc98c90) at refs/files-backend.c:2792

pstack中的重要一行是第一个＆＃39;＃13＆＃39;，它似乎试图锁定＆＃39; refs / heads / master＆＃39;，但如果我检查我的git存储库：

[atlbitbucket@dubengvm494 fw]$ cd refs/heads
[atlbitbucket@dubengvm494 heads]$ ll
total 0

这是git中的错误吗？ （版本2.13）我原以为它会说像无效的git存储库，没有refs founds＆＃39;。相反，它仍然锁定在这个循环中：

    while (1) {
            int was_alias = run_argv(&argc, &argv);
            if (errno != ENOENT)
                    break;
            if (was_alias) {
                    fprintf(stderr, "Expansion of alias '%s' failed; "
                            "'%s' is not a git command\n",
                            cmd, argv[0]);
                    exit(1);
            }
            if (!done_help) {
                    cmd = argv[0] = help_unknown_cmd(cmd);
                    done_help = 1;
            } else
                    break;
    }
