开多进程获取id会重复

在实际运用中.老系统想要迁移到此ID方案时,需要一个依据数据原有时间生成ID的接口.

因为我在设计数据库时,利用新ID的特点,我会省一个数据创建时间字段.因为ID中可以取到．
所以在老系统迁移时就需要一个这样的接口.从时间来获得唯一ID.这样以迁移后,我就能从ID中获得该数据的生成时间.

头文件malloc.h在MacOS的路径为sys/malloc.h，建议加上对系统的判定

嗨，您好。现在需要一个高性能的id生成器，碰巧看到了你的donkeyid。但是我在release里没有看到1.0版本，请问1.0版本稳定了吗？

`cp ./.libs/donkeyid.so /home/donkeyid-donkeyid-0.7/donkeyid/modules/donkeyid.so
cp ./.libs/donkeyid.lai /donkeyid-donkeyid-0.7/donkeyid/modules/donkeyid.la
; Local Variables:

PATH="$PATH:/sbin" ldconfig -n /home/donkeyid-donkeyid-0.7/donkeyid/modules

Libraries have been installed in:
; Local Variables:
/home/donkeyid-donkeyid-0.7/donkeyid/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:

• add LIBDIR to the `LD_LIBRARY_PATH' environment variable
  during execution
• add LIBDIR to the `LD_RUN_PATH' environment variable
  during linking
• use the `-Wl,--rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.`

我已经在/etc/ld.so.conf加上了路径，make clean之后，重新编译还是错误，但是可以生成so文件，加入到php.ini中，提示“段错误”

能否提供个ZTS版的拓展编译呢？测试发现在ZTS版本上无法使用该扩展

现在一台机器上启动多个相同的进程，id会有重复。

在make时出错

编译成功后, 追加 extension 后, 出现上述错误信息.

php版本 PHP 7.0.9
php -v

README发号算法例图中workId的标识未去掉。

$data = dk_parse_id("6492052405004271616")
json_encode后是这样的:{"time\u0000":"1547825909854","node_id\u0000":0,"sequence\u0000":0}
导致$data['time'] 获取不到值

我想请教下这种问题我该如何解决,谢谢!

测试了下 donkeyid 发现 ini_set 设置 node_id 无效啊，帮忙看看，这块因为现在要用到微服务中，希望提供下能动态修改node_id 的方法，这样更方便于使用。

public function http_donkeyid() {
ini_set('donkeyid.node_id',3);
$donkeyid = dk_get_ts_id();
$multi = $this->http_input->get('multi');
if(!empty($multi) && intval($multi) > 0) {
$donkeyid = dk_get_ts_ids($multi);
}
$tsid = dk_get_ts_id();
$donkeyid['tsid'] = $tsid;
$dtid = dk_get_dt_id();
$donkeyid['dtid'] = $dtid;
$donkeyid['dk_parse_ts_id'] = dk_parse_ts_id($tsid);
$donkeyid['iniget'] = ini_get('donkeyid.node_id');
$this->http_output->end($donkeyid);
}

返回结果

snowflake 算法最高位不用，所以毫秒计时器用了41个bit，所以最多是2^42 -1，就相当于139年，如果你是用了42个bit的话，那么应该是2^43 -1。就相当于278年了。

本机节点不应从脚本设置.可放到PHP.INI中
当然.接口是可以留的..用户自己设置就用设置的.否则从PHP.INI中获取.

如题， donkeyid是基依赖swoole的吗？还是有swoole版本呢？
