|
||||

|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
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.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions

||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but

||||
excluding communication that is conspicuously marked or otherwise

||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
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
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(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.

||||
result of this License or out of the use or inability to use the

other commercial damages or losses), even if such Contributor

|
||||
- To add a module \(for example, Module A\) and print logs, perform the following steps:
|
||||
1. **Add the module ID. **
|
||||
|
||||
Add **HILOG\_MODULE\_A** to **base/hiviewdfx/interfaces/hilog\_lite/interfaces/native/kits/hilog\_lite**.
|
||||
|
||||
```
|
||||
typedef enum {
|
||||
/** DFX */
|
||||
HILOG_MODULE_HIVIEW = 0,
|
||||
/** System Module A */
|
||||
HILOG_MODULE_A,
|
||||
/** Maximum number of modules */
|
||||
HILOG_MODULE_MAX
|
||||
} HiLogModuleType;
|
||||
```
|
||||
|
||||
|
||||
1. **Register the module.**
|
||||
|
||||
Add the following code to the initialization process of Module A to register it with the log framework:
|
||||
|
||||
```
|
||||
HiLogRegisterModule(HILOG_MODULE_A, "A");
|
||||
```
|
||||
|
||||
|
||||
1. **Modify the static configuration of the DFX framework.**
|
||||
|
||||
Modify **g\_hiviewConfig** in the following file as required. By default, modification is not required and logs are output to the serial port.
|
||||
|
||||
```
|
||||
utils/lite/hiview_config.c
|
||||
```

## Small System<a name="s33e0a62bc1dd4a2a9578fc22bd023f11"></a>
|
||||
|
||||
**Native C and C++ APIs**
|
||||
|
||||
Available HiLog APIs are as follows:
|
||||
|
||||
```
|
||||
HILOG_DEBUG(type, ...)
|
||||
HILOG_INFO(type, ...)
|
||||
HILOG_WARN(type, ...)
|
||||
HILOG_ERROR(type, ...)
|
||||
HILOG_FATAL(type, ...)
|
||||
```
|
||||
|
||||
Usage guidelines:
|
||||
|
||||
1. Define the log tag.
|
||||
|
||||
2. Perform local debugging. \(The domain value **0** can be used.\)
|
||||
|
||||
3. Include the header file using **\#include <hilog/log.h\>**.
|
||||
|
||||
4. Add the dependency library **libhilog** to **BUILD.gn**.
|
||||
|
||||
API rules:
|
||||
|
||||
1. The format specifier is labeled public by default, for example, **HILOGI\("Hello World\\n"\); \>\> Hello World**.
|
||||
|
||||
2. The formatted parameter is labeled private by default, for example, **HILOGI\("Age is %d\\n", 10\); \>\> Age is <private\>**.
|
||||
|
||||
3. Parameters labeled **%\{private\}** are private data, for example, **HILOGI\("Age is %\{private\}d\\n", 10\); \>\> Age is <private\>**.
|
||||
|
||||
4. Parameters labeled **%\{public\}** are public data, for example, **HILOGI\("Age is %\{public\}d\\n", 10\); \>\>Age is 10**.

**Viewing logs**
|
||||
|
||||
1. Go to the **/storage/data/log/** directory to view hilog logs generated during debugging.
|
||||
|
||||
2. Run the **hilogcat** command to view hilog logs in real time.
|
||||
|
||||
|
||||
**Log system architecture**
|
||||
|
||||
|
||||
|
||||
1. hilogtask: log task in the kernel
|
||||
- This is a task or thread of the Linux kernel. It is initialized during system startup.
|
||||
- When a module in the kernel calls the log API, the formatted log content is transferred to the task and stored in a ringbuffer.
|
||||
- When the log API is called in the user space, the formatted log content is written into the driver node by calling **ioctl**. The driver node then sends the log content to hilogtask, and hilogtask stores the log content in the ringbuffer.
|
||||
|
||||
2. hilogcatd: storage for logs in user space
|
||||
- This is a user-space process. It periodically reads the log content from the ringbuffer and stores it in the log file.
|
||||
- Log files can be compressed in **gzip** format by using **zlib**.
|
||||
- The size of a single file and the number of files can be configured during compilation.
|
||||
|
||||
3. hilogcat: command line tool for viewing logs
|
||||
|
||||
This tool reads the log content in the ringbuffer via the kernel driver API, and then outputs the content to **stdout**.
|
||||
|
||||
4. ringbuffer: configurable buffer for logs
|
||||
- The ringbuffer size can be configured during compilation.

轻量系统整体代码使用标准C开发。
|
||||
|
||||
## 使用-轻量系统<a name="sd6e99f792bc942f9bb5aa92111be7aff"></a>
|
||||
|
||||
- **以下以A模块为例说明如何添加模块并进行日志打印。**
|
||||
1. **第一步添加模块ID**
|
||||
|
||||
在“base/hiviewdfx/hilog\_lite/interfaces/native/kits/hilog\_lite/hiview\_log.h“中添加HILOG\_MODULE\_A定义。
|
||||
|
||||
```
|
||||
typedef enum {
|
||||
/** DFX */
|
||||
HILOG_MODULE_HIVIEW = 0,
|
||||
/** System Module A */
|
||||
HILOG_MODULE_A,
|
||||
/** Maximum number of modules */
|
||||
HILOG_MODULE_MAX
|
||||
} HiLogModuleType;
|
||||
```
|
||||
|
||||
|
||||
1. **第二步模块注册**
|
||||
|
||||
在A模块的初始化流程中添加如下代码，注册模块到日志框架中：
|
||||
|
||||
```
|
||||
HiLogRegisterModule(HILOG_MODULE_A, "A");
|
||||
```
|
||||
|
||||
|
||||
1. **第三步日志打印**
|
||||
|
||||
在需要打印日志的.c文件中 \#include "log.h"，调用如下接口：
|
||||
|
||||
HILOG\_INFO\(HILOG\_MODULE\_A,“log test: %d”, 88\);
|
||||
|
||||

**日志查看**
|
||||
|
||||
1. debug版本hilog日志会保存到/storage/data/log/目录下面。
|
||||
|
||||
2. 可以执行hilogcat实时查看hilog日志。
|
||||
|
||||
|
||||
**日志系统架构**
|
||||
|
||||
|
||||
|
||||
1. hilogtask流水日志的内核任务。
|
||||
- 此功能是一个linux内核的任务或者线程，在系统启动时初始化。
|
||||
- 当内核中一个模块调用它的日志接口，将格式化好的日志内容传输给改任务，并将其存储在一个环形缓冲区中 。
|
||||
- 当用户态调用日志接口，将格式化好的日志内容通过ioctl调用写入驱动节点，驱动节点再将日志内容发送到hilogtask，hilogtask将日志内容存储到环形缓冲区中。
|
||||
|
||||
2. hilogcatd用户态日志存储服务。
|
||||
- 这是一个用户态的进程，负责定时将内核的ringbuffer读取出来，存储到日志文件中。
|
||||
- 日志文件输出支持gzip压缩，使用zlib
|
||||
- 存储文件的单个文件大小，文件个数可在编译时配置。
|
||||
|
||||
3. hilogcat日志查看命令行工具。
|
||||
|
||||
从内核驱动接口读取ringbuffer内容，输出到标准输出。
|
||||
|
||||
4. 支持日志缓冲区可配置。
|
||||
- 编译时可以配置日志缓冲区的大小。

* Before outputting logs, you must define the service domain, and log tag, use the function with

* the specified log type and level, and specify the privacy identifier.\n
|
||||
* <ul><li>Service domain: used to identify the subsystem and module of a service. Its value is a hexadecimal

* integer ranging from 0x0 to 0xFFFFF. The recommended format is 0xAAABB, where AAA indicates the subsystem

* and BB indicates the module.</li> \n
|

* <li>Log tag: a string used to identify the class, file, or service behavior.</li> \n
|
||||
* <li>Log level: <b>DEBUG</b>, <b>INFO</b>, <b>WARN</b>, <b>ERROR</b>, and <b>FATAL</b></li> \n
|
||||
* <li>Parameter format: a printf format string that starts with a % character, including format specifiers
|
||||
* and variable parameters.</li> \n
|
||||
* <li>Privacy identifier: {public} or {private} added between the % character and the format specifier in
|
||||
* each parameter. Note that each parameter has a privacy identifier. If no privacy identifier is added,
|
||||
* the parameter is considered to be <b>private</b>.</li></ul> \n

* Sample code:\n
|

* Defining the service domain and log tag:\n
|
||||
* #define LOG_DOMAIN MY_SUBSYSTEM_MODULE // MY_SUBSYSTEM_MODULE=0x00201, where 002 indicates the subsystem and
|
||||
* 01 indicates the module.\n

* #define LOG_TAG "MY_TAG"\n

* Outputting logs:\n

* Output result:\n
|
