[FYI] Use of AOSP mirror - linaro-android

26 Jul 2016


      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
https://source.android.com/source/downloading.html#using-a-local-mirror:
$ 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 http://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,
Yongqin Liu
