Hi, All

If you need often sync different versions of AOSP from google or internet, 

It's better for you to have a local AOSP mirror, it will help you to repo sync

AOSP source much faster.

1. Create a local AOSP mirror

    Here is the link about how to create local AOSP mirror:

    https://source.android.com/source/downloading.html#using-a-local-mirror

$ mkdir -p /usr/local/aosp/mirror
$ cd /usr/local/aosp/mirror
$ repo init -u https://android.googlesource.com/mirror/manifest --mirror
$ repo sync

2. Use a local AOSP mirror

    As described  here:

$ mkdir -p /usr/local/aosp/master

$ cd /usr/local/aosp/master
$ repo init -u /usr/local/aosp/mirror/platform/manifest.git
$ repo sync

3. linaro_android_build_cmds.sh supports to use mirror now.

    Linaro releases each android build with a linaro_android_build_cmds.sh script which helps you

    repo sync and build the android source to reproduce the build.

    It supports using local mirror from now on, like:

./linaro_android_build_cmds.sh -t -u <url-aosp-mirror-manifest>    

    

    For other options of linaro_android_build_cmds.sh, please check the help or the release page of that build.

If you do not use hackbox for Android building, you can ignore the following part now.

4. Use AOSP mirror on hackbox.linaro.org

   Since I often use hackbox to build android for different versions, I created a local AOSP mirror on hackbox,

   and it is synced every 6 hours.

   **** If you have AOSP mirror on hackbox too, let's talk to keep only one for disk space.****

   The AOSP mirror path is here:

  /home/yongqin.liu/aosp-mirror/

   

   It's very similar to sync from AOSP or android-git.linaro.org, you can use it like this:

mkdir aosp-master

cd aosp-master

repo init -u /home/yongqin.liu/aosp-mirror/platform/manifest.git -p linux

repo sync

   Or use it with linaro_android_build_cmds.sh like this:

./linaro_android_build_cmds.sh -u /home/yongqin.liu/aosp-mirror/platform/manifest.git -t -y

If you can specify --depth=1 or -g option for your repo init command, it will help you repo sync more faster.

Like with,

      repo init -u /home/yongqin.liu/aosp-mirror/platform/manifest.git -p linux --depth=1

It took less than 10 minutes to finish the following repo sync command;

      $time repo sync -j8 

      .......

      real 7m22.535s

      user 8m41.735s

      sys 2m13.250s

      $

Best Regards,
