This adds three new features:
- <original-package android:name="com.foo" /> manifest tag.
This allows an .apk to specify another package it originally came from,
propagating all state and data from the old to new package.
- <adopt-permissions android:name="com.foo" /> manifest tag.
In some more complicated cases, a new .apk may be a combination
of multiple older .apks that each declared their own permissions.
This allows you to propagate the permissions from these other
.apks into the new one.
- A new system/etc/updatecmds directory.
You can place files here which describe data files to move from
one package to another. (See below for details.)
Also in this change: we now clean up the data directories of
.apks that disappear from the system image, and some improvements
to logging and reporting error messages.
A typical file in the updatecmds directory looks like this:
-------
com.google.android.gsf:com.google.android.providers.talk
databases/talk.db
com.google.android.gsf:com.google.android.googleapps
databases/gls.db
-------
This says that for com.google.android.sfs, there are two packages to
move files from:
From com.google.android.providers.talk, the file databases/talk.db.
From com.google.android.googleapps, the file databases/gls.db
As part of moving the file, its owner will be changed from the old
package to whoever is the owner of the new package's data directory.
If those two files had existed, after booting you would now have the
files:
/data/data/com.google.android.gsf/databases/talk.db
/data/data/com.google.android.gsf/databases/gls.db
Note that all three of these facilities assume that the older .apk
is completely removed from the newer system. The WILL NOT work
correctly if the older .apk still remains.
Add new remote interface to do temporary copies. The new
remote stub handling is done on mHandler thread and doesn't need locking
for now.
Add new InstallArgs class and subclasses to isolate cases for installation.
Move resource deletion for failed installs/upgrades to later on in installation
cycle.
Fix code path for forward locked apps when using scanPackageLI
TODO's
Fix installation paths to completely use InstallArgs based design later on.
Get rid of using flags in various install/uninstall code paths.
Ideally InstallArgs should be created using these flags and used in the
rest of the code.
Function renames.
Revisit mount api's.
to install an app on sdcard, just resources.
Add new install path for /asec in installd.
ignore . when checking for apk path since the sdcard packages id'ed
by package name.
Add new -s option to adb shell pm
Refactor fwd locked from scanMode to ApplicationInfo.
Add new flag for sd install
Add new parse flags for fwd locking and installing on sdcard
New mock api's in PackageManagerService to invoke MountService api's. These
will be refactored again and so have been wrapped internally.
Some error codes in PackageManager
Changes in PackageManagerService to use mPath and mScanPath during installation
and switch to using PackageParser.Package.applicationInfo attributes for
source and public resource directories.
Some known issues that will be addressed later
using system_uid for now. needs some tinkering with uid and packagesetting creation to use the actual app uid
error handling from vold not very robust. ignoring lot of things for now
sending a delayed destroy to delete packages. will revisit later
revisit temp file creation later. just copy for now
