# ip2region xdb golang generation implementation
|
|
|
|
# Program Compilation
|
|
|
|
Compile to get the xdb_maker executable through the following method:
|
|
|
|
```
|
|
# cd to the golang maker root directory
|
|
make
|
|
```
|
|
|
|
After successful compilation, a xdb_maker executable file will be generated in the current directory.
|
|
|
|
# `xdb` Data Generation
|
|
|
|
Generate the ip2region.xdb binary file via the `xdb_maker gen` command:
|
|
|
|
```
|
|
./xdb_maker gen [command options]
|
|
options:
|
|
--src string source ip text file path
|
|
--dst string destination binary xdb file path
|
|
--version string IP version, options: ipv4/ipv6, specify this flag so you don't get confused
|
|
--field-list string field index list imploded with ',' eg: 0,1,2,3-6,7
|
|
--log-level string set the log level, options: debug/info/warn/error
|
|
```
|
|
|
|
For example, generate the xdb file to the current directory using the default source data under the repository's data/ directory:
|
|
|
|
```bash
|
|
# ipv4
|
|
./xdb_maker gen --src=../../data/ipv4_source.txt --dst=./ip2region_v4.xdb --version=ipv4
|
|
# ipv6
|
|
./xdb_maker gen --src=../../data/ipv6_source.txt --dst=./ip2region_v6.xdb --version=ipv6
|
|
```
|
|
|
|
For custom data fields during the generation process, please refer to [xdb-文件生成#自定义数据字段](https://ip2region.net/doc/data/xdb_make#field-list)
|
|
|
|
# `xdb` Data Search
|
|
|
|
Test the input IP via the `xdb_maker search` command:
|
|
|
|
```
|
|
➜ golang git:(v2.0_xdb) ✗ ./xdb_maker search
|
|
./xdb_maker search [command options]
|
|
options:
|
|
--db string ip2region binary xdb file path
|
|
```
|
|
|
|
For example, run a search test using the built-in xdb file:
|
|
|
|
```bash
|
|
# ipv4
|
|
./xdb_maker search --db=../../data/ip2region_v4.xdb
|
|
ip2region xdb search test program,
|
|
source xdb: ../../data/ip2region_v4.xdb (IPv4)
|
|
commands:
|
|
loadIndex : load the vector index for search speedup.
|
|
clearIndex: clear the vector index.
|
|
quit : exit the test program
|
|
ip2region>> 58.251.30.115
|
|
{region:中国|广东省|深圳市|联通|CN, iocount:2, took:27.893µs}
|
|
ip2region>> 1.2.3.4
|
|
{region:Australia|Queensland|Brisbane|0|AU, iocount:5, took:58.746µs}
|
|
|
|
# ipv6
|
|
./xdb_maker search --db=../../data/ip2region_v6.xdb
|
|
ip2region xdb search test program,
|
|
source xdb: ../../data/ip2region_v6.xdb (IPv6)
|
|
commands:
|
|
loadIndex : load the vector index for search speedup.
|
|
clearIndex: clear the vector index.
|
|
quit : exit the test program
|
|
ip2region>> 2604:bc80:8001:11a4:ffff:ffff:ffff:ffff
|
|
{region:United States|Florida|Miami|velia.net Internetdienste GmbH|US, iocount:15, took:140.942µs}
|
|

# `xdb` Data Editing
|
|
|
|
Edit the raw IP data via the `xdb_maker edit` command:
|
|
|
|
```
|
|
./xdb_maker edit [command options]
|
|
options:
|
|
--src string source ip text file path
|
|
--version string IP version, options: ipv4/ipv6, specify this flag so you don't get confused
|
|
```
|
|
|
|
For example, opening `./data/ipv4_source.txt` with the editor will show the following operation panel:
|
|
|
|
```bash
|
|
./xdb_maker edit --src=../../data/ipv4_source.txt --version=ipv4
|
|
init the editor from source @ `../../data/ipv4_source.txt` ...
|
|
all segments loaded, length: 683591, elapsed: 479.73743ms
|
|
command list:
|
|
put [segment] : put the specifield $segment
|
|
put_file [file] : put all the segments from the specified $file
|
|
list [offset] [size] : list the first $size segments start from $offset
|
|
save : save all the changes to the destination source file
|
|
quit : exit the program
|
|
help : print this help menu
|
|
editor>>
|
|
```
|
|
|
|
Modify the location information of a specified IP segment using the `put` command, for example:
|
|
|
|
```bash
|
|
editor>> put 36.132.128.0|36.132.147.255|中国|黑龙江省|哈尔滨市|移动|CN
|
|
Put(36.132.128.0|36.132.147.255|中国|黑龙江省|哈尔滨市|移动|CN): Ok, with 1 deletes and 2 additions
|
|
*editor>>
|
|
```
|
|
|
|
Batch load modifications from a file using the `put_file` command. The IP segments in the file do not need to be as strict as the data in `./data/ipvx_source.txt`; they do not need to be continuous, and it does not matter if different IP segments overlap. The editor will automatically analyze and process them, for example:
|
|
|
|
```bash
|
|
*editor>> put_file ../../data/ip.test.txt
|
|
PutFile(../../data/ip.test.txt): Ok, with 25 deletes and 25 additions
|
|
*editor>>
|
|
```
|
|
|
|
Save modifications using the `save` command. After saving successfully, you can re-generate the xdb from the modified raw IP file using the commands mentioned above:
|
|
|
|
```bash
|
|
*editor>> save
|
|
all segments saved to ../../data/ip.merge.txt
|
|
editor>>
|
|
```
|

# bench Test
|
|
|
|
If you have generated the `xdb` file yourself, please ensure you run the following `xdb_maker bench` command to verify the correctness of the generated `xdb` file:
|
|
|
|
```
|
|
./xdb_maker bench [command options]
|
|
options:
|
|
--db string ip2region binary xdb file path
|
|
--src string source ip text file path
|
|
--version string IP version, options: ipv4/ipv6, specify this flag so you don't get confused
|
|
--log-level string set the log level, options: debug/info/warn/error
|
|
--ignore-error bool keep going if bench failed
|
|
```
|
|
|
|
For example: use the source files under data to bench test the xdb files in data:
|
|
|
|
```bash
|
|
# ipv4
|
|
./xdb_maker bench --db=../../data/ip2region_v4.xdb --src=../../data/ipv4_source.txt --version=ipv4
|
|
|
|
#ipv6
|
|
./xdb_maker bench --db=../../data/ip2region_v6.xdb --src=../../data/ipv6_source.txt --version=ipv6
|
|
```
|
|
|
|
*Please note that the `src` file used for the bench test must be the same as the source file used to generate the xdb*.
|
|
If an error occurs during execution, it will stop immediately. You can also execute with the `--ignore-error=true` parameter to ignore errors and view the failed statistics at the end.
