localize android repo -- more more..

現在 repo 好像有點修改了，所以上次那篇： http://r40eubuntu.blogspot.tw/2011/05/code-default.html
要作一些修改...

---

複習：

要把整個 android source 都納入 repo 管理，並且放在 local server 中。

首先 repo init, sync 時，一定要用 --mirror 參數，否則 manifest.xml 的內容 (path) 不會正確。

這次 manifest.xml 的內容有點改變，以往 remote server name:address 是寫在 manifest.xml 裡。
現在好像會在 repo init 時，依照 init -u 的 source 改變。

所以一旦 mirror 到 local server 後，不用修改 manifest.xml。
之後 從 local server 作 repo init 的，都會從 local server clone。

關鍵好像是在 .repo/manifests.git/config

以前的 bsp 會提供一個修改過的 default.xml。現在(10.4)沒了，要自己刪檔，所以刪完 project 後， repo 就會 fail -- folder 與 manifest.xml 內容不一致。

---

次序錯了，一開始 manifest 開 branch 時，要用 imx_r10.4，所以那些新加的 project，也要tag imx_r10.4。

這樣 c_patch 完後，那些修改都可以直接 push (?)。


避免 雞 - 蛋 問題， test repo 的 client folder (就是完整 clone repo 的 folder) 最好有兩個。
一個測試用。一個是用來上 patch。

現在 google 都教人作 mirror 了...http://source.android.com/source/downloading.html#using-a-local-mirror

copy:



When using several clients, especially in situations where bandwidth is scarce, it is better to create a local mirror of the entire server content, and to sync clients from that mirror (which requires no network access). The download for a full mirror is smaller than the download of two clients, while containing more information.

These instructions assume that the mirror is created in /usr/local/aosp/mirror. The first step is to create and sync the mirror itself, which uses close to 13GB of network bandwidth and a similar amount of disk space. Notice the --mirror flag, which can only be specified when creating a new client:

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

Once the mirror is synced, new clients can be created from it. Note that it's important to specify an absolute path:

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

Finally, to sync a client against the server, the mirror needs to be synced against the server, then the client against the mirror:

$ cd /usr/local/aosp/mirror
$ repo sync
$ cd /usr/local/aosp/master
$ repo sync

It's possible to store the mirror on a LAN server and to access it over NFS, SSH or Git. It's also possible to store it on a removable drive and to pass that drive around between users or between machines.
