adb_var_shell2の中身、１と２の違いは、エラーのリダイレクトが違うだけだな。

# Run a command through 'adb shell' and captures its standard output

run-as: Package 'com.my.android.app' has corrupt installation

cat: /tmp/ndk-m_fujii: Is a directory

corrupt installationなので、うまくインストールできていないらしい。

sed -e '$d'で最終行を表示しないようにしている。

$ sed -e '$d' ndk-gdb-cmdout-sD4ie2
run-as: Package 'com.my.android.app' has corrupt installation

$ sed -e '' ndk-gdb-cmdout-sD4ie2

adb shell上でのコマンドがエラーになっている。
$ run-as com.my.android.app /system/bin/sh -c pwd
run-as com.my.android..app /system/bin/sh -c pwd

Usage: run-as []

run-asコマンドのソースを見ると、/data/system/packages.list というファイルをopenしてreadしています。このファイルはテキストファイルで、各アプリケーションのパッケージ名、UID、デバッグ可否、ディレクトリが書かれています。run-asコマンドはこのファイルからそのアプリケーションがデバッグを許可しているかを調べ、許可している場合のみそのアプリケーションと同じUIDで指定のコマンドを実行するわけです。

ちゃんと登録されてるみたい。13KB弱ある。

$ cat /data/system/packages.list | grep com.my
com.my.lim.android.app 10133 1 /data/data/com.my.android.app

$ ls -l /data/system | grep pack*
ls -l /data/system | grep pack*

2.3.7だと#define PACKAGES_LIST_BUFFER_SIZE 65536になってる。
2.3は、#define PACKAGES_LIST_BUFFER_SIZE 8192だ。

Gerritの方は特に書いてないな。

GitHubの方にあった。
run-as: Bump the size of the internal packages list buffer.
This patch increases the size of the internal buffer used by run-as
to store the content of /data/system/packages.list from 8KB to 64KB.

Apr 27, 2011なんだ。
run-as can't read packages after the 8192nd byte of /data/system/packages.list

2.3.3だと、修正まえなのかな？

2011年2月9日(SDK 2.3.3)

2011年4月28日(2.3.4)

2011年7月25日(2.3.5)

アプリをほとんど削除したけど、これ以上削れない。だめっぽいな。
