## Source Code Acquisition


### Prerequisites

1. Register your account with Gitee.

2. Register an SSH public key for access to Gitee.

3. Install the [git client](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) and [git-lfs](https://gitee.com/vcs-all-in-one/git-lfs?_from=gitee_search#downloading), and configure user information.
   ```
   git config --global user.name "yourname"
   git config --global user.email "your-email-address"
   git config --global credential.helper store
   ```

4. Run the following commands to install the **repo** tool:
   ```
   curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo  # If you do not have the permission, download the tool to another directory and configure it as an environment variable by running the chmod a+x /usr/local/bin/repo command.
   pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests
   ```


### Acquiring Source Code Using the repo Tool

**Method 1 (recommended)**

Use the **repo** tool to download the source code over SSH. (You must have an SSH public key for access to Gitee.)


Obtain the source code from the version tag, which is the same as that released with the version.
```
repo init -u git@gitee.com:openharmony/manifest.git -b refs/tags/OpenHarmony-v4.1.1-Release --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
```

**Method 2**

Use the **repo** tool to download the source code over HTTPS.

Obtain the source code from the version tag, which is the same as that released with the version.
```
repo init -u https://gitee.com/openharmony/manifest -b refs/tags/OpenHarmony-v4.1.1-Release --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'
```

## What's New

This version does not involve API updates.

## Resolved Issues

**Table 3** Resolved issues

| Issue No.| Description| 
| -------- | -------- |
| I8WP8M | Create a large folder by moving an application icon on the home screen to overlap with another application icon, and then move an application icon out of the folder. Repeat this operation. Five minutes later, a total of about 25 MB memory is leaked on the launcher, that is, a 673.68 KB memory leak for each operation.|
| I9A089 | There is a moderate probability that system freezing occurs in the foundation process due to SERVICE_BLOCK.|
| I90A2N | There is a possibility that app freezing occurs in the com.ohos.systemui process because THREAD_BLOCK_6S is stuck in the libeventhandler.z.so stack.|
| I9CGOZ | There is a high probability that app freezing occurs in the com.ohos.camera process because THREAD_BLOCK_6S is stuck in the libcamera_framework.z.so stack.|
| I8QH9S | There is a low probability that a C++ crash occurs in libnative_appdatafwk.z.so of the os.settingsdata thread of the com.ohos.settingsdata process.|
| I963TL | There is a low probability that a C++ crash occurs in libark_jsruntime.so of the com.ohos.mms thread of the com.ohos.mms process.|
| I98KIG | There is a low probability that app freezing occurs in the com.ohos.camera process because THREAD_BLOCK_6S is stuck in the libcamera_framework.z.so stack.|
