Refactor IP region lookup to use external API
Replaced the local ip2region database and related PHP classes with an external API (ip.asbid.cn) for IP region lookup in functions.php. Removed the entire ip2region directory and its dependencies, simplifying maintenance and reducing local storage requirements. Updated caching logic to store API results for one month. Also updated the theme version in index.php to 1.1.

Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work

(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain

separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,

|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the

Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of

|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

# Ip2region 是什么
|
||||
|
||||
ip2region v2.0 - 是一个离线IP地址定位库和IP定位数据管理框架，10微秒级别的查询效率，提供了众多主流编程语言的 `xdb` 数据生成和查询客户端实现。
|
||||
|
||||
# Ip2region 特性
|
||||
|
||||
### 1、标准化的数据格式
|
||||
|
||||
每个 ip 数据段的 region 信息都固定了格式：`国家|区域|省份|城市|ISP`，只有中国的数据绝大部分精确到了城市，其他国家部分数据只能定位到国家，后前的选项全部是0。
|
||||
|
||||
### 2、数据去重和压缩
|
||||
|
||||
`xdb` 格式生成程序会自动去重和压缩部分数据，默认的全部 IP 数据，生成的 ip2region.xdb 数据库是 11MiB，随着数据的详细度增加数据库的大小也慢慢增大。
|
||||
|
||||
### 3、极速查询响应
|
||||
|
||||
即使是完全基于 `xdb` 文件的查询，单次查询响应时间在十微秒级别，可通过如下两种方式开启内存加速查询：
|
||||
|
||||
1. `vIndex` 索引缓存 ：使用固定的 `512KiB` 的内存空间缓存 vector index 数据，减少一次 IO 磁盘操作，保持平均查询效率稳定在10-20微秒之间。
|
||||
2. `xdb` 整个文件缓存：将整个 `xdb` 文件全部加载到内存，内存占用等同于 `xdb` 文件大小，无磁盘 IO 操作，保持微秒级别的查询效率。
|
||||
|
||||
### 4、IP 数据管理框架
|
||||
|
||||
v2.0 格式的 `xdb` 支持亿级别的 IP 数据段行数，region 信息也可以完全自定义，例如：你可以在 region 中追加特定业务需求的数据，例如：GPS信息/国际统一地域信息编码/邮编等。也就是你完全可以使用 ip2region 来管理你自己的 IP 定位数据。

# 并发查询必读
|
||||
|
||||
全部查询客户端的 search 接口都 <b>不是</b> 并发安全的实现，不同进程/线程/协程需要通过创建不同的查询对象来安全使用，并发量很大的情况下，基于文件查询的方式可能会导致打开文件数过多的错误，请修改内核的最大允许打开文件数(fs.file-max=一个更高的值)，或者将整个xdb加载到内存进行安全并发使用。
|
||||
|
||||
# 相关备注
|
||||
|
||||
### 1、使用声明
|
||||
|
||||
ip2region 重点在于<b>研究 IP 定位数据的存储设计和各种语言的查询实现</b>，并没有原始 IP 数据的支撑，本项目不保证及时的数据更新，没有也不会有商用版本，你可以使用自定义的数据导入 ip2region 进行管理。
|
||||
|
||||

# 关于 ip2region v2.0 的 PHP 用法
|
||||
|
||||
### 完全基于文件的查询
|
||||
|
||||
```php
|
||||
$dbFile = "ip2region.xdb file path";
|
||||
try {
|
||||
$searcher = XdbSearcher::newWithFileOnly($dbFile);
|
||||
} catch (Exception $e) {
|
||||
printf("failed to create searcher with '%s': %s\n", $dbFile, $e);
|
||||
return;
|
||||
}
|
||||
|
||||
$ip = '1.2.3.4';
|
||||
$sTime = XdbSearcher::now();
|
||||
$region = $searcher->search($ip);
|
||||
if ($region === null) {
|
||||
// something is wrong
|
||||
printf("failed search(%s)\n", $ip);
|
||||
return;
|
||||
}
|
||||
|
||||
printf("{region: %s, took: %.5f ms}\n", $region, XdbSearcher::now() - $sTime);
|
||||
|
||||
// 备注：并发使用，每个线程或者协程需要创建一个独立的 searcher 对象。
|
||||
```
|
||||
|
||||
### 缓存 `VectorIndex` 索引
|
||||
|
||||
如果你的 php 母环境支持，可以预先加载 vectorIndex 缓存，然后做成全局变量，每次创建 Searcher 的时候使用全局的 vectorIndex，可以减少一次固定的 IO 操作从而加速查询，减少 io 压力。
|
||||
|
||||
```php
|
||||
// 1、从 dbPath 加载 VectorIndex 缓存，把下述的 vIndex 变量缓存到内存里面。
|
||||
$vIndex = XdbSearcher::loadVectorIndexFromFile($dbPath);
|
||||
if ($vIndex === null) {
|
||||
printf("failed to load vector index from '%s'\n", $dbPath);
|
||||
return;
|
||||
}
|
||||
|
||||
// 2、使用全局的 vIndex 创建带 VectorIndex 缓存的查询对象。
|
||||
try {
|
||||
$searcher = XdbSearcher::newWithVectorIndex($dbFile, $vIndex);
|
||||
} catch (Exception $e) {
|
||||
printf("failed to create vectorIndex cached searcher with '%s': %s\n", $dbFile, $e);
|
||||
return;
|
||||
}
|
||||
|
||||
// 3、查询
|
||||
$sTime = XdbSearcher::now();
|
||||
$region = $searcher->search('1.2.3.4');
|
||||
if ($region === null) {
|
||||
printf("failed search(1.2.3.4)\n");
|
||||
return;
|
||||
}
|
||||
|
||||
printf("{region: %s, took: %.5f ms}\n", $region, XdbSearcher::now() - $sTime);
|
||||
|
||||
// 备注：并发使用，每个线程或者协程需要创建一个独立的 searcher 对象，但是都共享统一的只读 vectorIndex。
|
||||
```
|
||||
|
||||
### 缓存整个 `xdb` 数据
|
||||
|
||||
如果你的 PHP 母环境支持，可以预先加载整个 `xdb` 的数据到内存，这样可以实现完全基于内存的查询，类似之前的 memory search 查询。
|
||||
|
||||
```php
|
||||
// 1、从 dbPath 加载整个 xdb 到内存。
|
||||
$cBuff = XdbSearcher::loadContentFromFile($dbPath);
|
||||
if ($cBuff === null) {
|
||||
printf("failed to load content buffer from '%s'\n", $dbPath);
|
||||
return;
|
||||
}
|
||||
|
||||
// 2、使用全局的 cBuff 创建带完全基于内存的查询对象。
|
||||
try {
|
||||
$searcher = XdbSearcher::newWithBuffer($cBuff);
|
||||
} catch (Exception $e) {
|
||||
printf("failed to create buffer cached searcher: %s\n", $dbFile, $e);
|
||||
return;
|
||||
}
|
||||
|
||||
// 3、查询
|
||||
$sTime = XdbSearcher::now();
|
||||
$region = $searcher->search('1.2.3.4');
|
||||
if ($region === null) {
|
||||
printf("failed search(1.2.3.4)\n");
|
||||
return;
|
||||
}
|
||||
|
||||
printf("{region: %s, took: %.5f ms}\n", $region, XdbSearcher::now() - $sTime);
|
||||
|
||||
// 备注：并发使用，用整个 xdb 缓存创建的 searcher 对象可以安全用于并发。
|
||||
```
|
||||
|
||||
# 查询测试
|
||||
|
||||
通过 `search_test.php` 脚本来进行查询测试：
|
||||
|
||||
```bash
|
||||
➜ php git:(v2.0_xdb) ✗ php ./search_test.php
|
||||
php ./search_test.php [command options]
|
||||
options:
|
||||
--db string ip2region binary xdb file path
|
||||
--cache-policy string cache policy: file/vectorIndex/content
|
||||
```
|
||||
|
||||
例如：使用默认的 data/ip2region.xdb 进行查询测试：
|
||||
|
||||
```bash
|
||||
➜ php git:(v2.0_xdb) ✗ php ./search_test.php --db=../../data/ip2region.xdb --cache-policy=vectorIndex
|
||||
ip2region xdb searcher test program, cachePolicy: vectorIndex
|
||||
type 'quit' to exit
|
||||
ip2region>> 1.2.3.4
|
||||
{region: 美国|0|华盛顿|0|谷歌, ioCount: 7, took: 0.04492 ms}
|
||||
ip2region>>
|
||||
```
|
||||
|
||||
输入 ip 即可进行查询测试。也可以分别设置 `cache-policy` 为 file/vectorIndex/content 来测试三种不同缓存实现的效率。
|
||||
|
||||
# bench 测试
|
||||
|
||||
通过 `bench_test.php` 脚本来进行自动 bench 测试，一方面确保 `xdb` 文件没有错误，另一方面通过大量的查询测试平均查询性能：
|
||||
|
||||
```bash
|
||||
➜ php git:(v2.0_xdb) ✗ php ./bench_test.php
|
||||
php ./bench_test.php [command options]
|
||||
options:
|
||||
--db string ip2region binary xdb file path
|
||||
--src string source ip text file path
|
||||
--cache-policy string cache policy: file/vectorIndex/content
|
||||
```
|
||||
|
||||
例如：通过默认的 data/ip2region.xdb 和 data/ip.merge.txt 来进行 bench 测试：
|
||||
|
||||
```bash
|
||||
➜ php git:(v2.0_xdb) ✗ php ./bench_test.php --db=../../data/ip2region.xdb --src=../../data/ip.merge.txt --cache-policy=vectorIndex
|
||||
Bench finished, {cachePolicy: vectorIndex, total: 3417955, took: 15s, cost: 0.005 ms/op}
|
||||
```
|
||||
|
||||
可以通过设置 `cache-policy` 参数来分别测试 file/vectorIndex/content 三种不同的缓存实现的的性能。
|
||||
@Note：请注意 bench 使用的 src 文件需要是生成对应的 xdb 文件的相同的源文件。
