This repository provides a cron-updated manifest for mirroring all of CodeAurora Android-related repositories.
mkdir -p /mirror/caf
cd /mirror/caf
repo init -u https://github.com/arter97/caf_mirror_manifest --mirror
repo sync -j16
It is recommended that you have an AOSP mirror already:
mkdir -p /mirror/aosp
cd /mirror/aosp
repo init -u https://android.googlesource.com/mirror/manifest --mirror
repo sync -j16
mkdir -p /mirror/caf
cd /mirror/caf
repo init -u https://github.com/arter97/caf_mirror_manifest --mirror --reference=/mirror/aosp
repo sync -j16
As of time of writing, the AOSP mirror takes 746 GiB and CAF mirror (when AOSP mirror is referenced) takes 20 GiB of storage.
We currently store AOSP mirror's device/ (kernel binary Git repositories are huge) and
platform/external/chromium-webview.git/ on a HDD with bind mounts to reduce SSD storage usage.
Those directories use 310 GiB of space with almost no benefit to use fast storage.
Note that while unmodified, upstream repositories from CAF or AOSP will use the mirror, custom ROM's repositories hosted on GitHub will not automatically benefit from the mirror.
For example, when you repo init Paranoid Android with --mirror to this mirror,
AOSPA/android_frameworks_base.git, AOSPA/android_packages_apps_Settings.git and the likes will not
automatically use the mirrored objects.
This is due to the name format difference in the XML.
Completely working around this is not worth the effort, but for android_frameworks_base and
android_packages_apps_Settings (2 repositories that take the most space in custom ROM's repositories),
it may be worth it to forcefully use the mirrored objects so that the initial clone is shorter.
To do this, perform a manual repo sync frameworks/base after repo init and ^C (Ctrl-C) after Git starts downloading.
Do the same with packages/apps/Settings.
With this, the initial Git structure is ready. After that:
echo /mirror/caf/platform/frameworks/base.git/objects > .repo/project-objects/AOSPA/android_frameworks_base.git/objects/info/alternates
rm -f .repo/project-objects/AOSPA/android_frameworks_base.git/objects/tmp_pack*
echo /mirror/caf/platform/packages/apps/Settings.git/objects > .repo/project-objects/AOSPA/android_packages_apps_Settings.git/objects/info/alternates
rm -f .repo/project-objects/AOSPA/android_packages_apps_Settings.git/objects/tmp_pack*
and perform a repo sync -j16 again.
This time, Git will reference the mirrored objects.
If you really want to use mirrors on custom ROMs because you have a bunch of them and want to reduce the total storage usage,
you can use repack.sh to repack Git objects to reference the mirrored objects.
If you want to run this yourself...
Creates legacy, system and vendor directory for CAF Git clones and pulls updates from them.
These directories are added to .gitignore.
Reads all LA.UM XML files from */*.xml and creates final default.xml.
Few repositories in older XML files are broken.
blacklist.txt includes several broken repositories so that the created manifest doesn't include those.
As of time of writing, the following repositories are broken and excluded via blacklist.txt:
platform/tools/vendor/google_prebuilts/arc
platform/vendor/google_easel
platform/vendor/google_paintbox
quic/la/toolchain/binutils
quic/le/live555
quic/le/platform/vendor/qcom-opensource/qmmf-sdk
quic/le/platform/vendor/qcom-opensource/qmmf-webserver
For cronjob registration. This is executed every 8 AM KST.
