For some time now the build system has included all the max image
sizes in a file in the META directory. Use these instead of needing
to parse the BoardConfig.mk file for the device at the time of
building an image or OTA package.
If the source target-files zip omits files needed to build the
recovery and/or boot images, leave them out instead of dying with an
error. This lets build like "generic-userdebug" work.
The ota and img building scripts contained some hardcoded 'linux-x86'
paths. Remove and replace with a slightly redefined -p option.
Modify Makefile to pass correct -p when building.
In python 2.5 and earlier, ZipFile.writestr(filename, data) results in
the file being added to the archive with permissions 000. (See
http://svn.python.org/view?view=rev&revision=65235.) Work around this
by creating a ZipInfo object and setting the permissions explicitly.
Use minigzip (from the zlib distribution, built in the android tree)
to compress images rather than the system install of gzip. This will
let us send useful patches for images since we can make zlib available
in the applypatch program.
Allow the user to set ANDROID_PW_FILE to the name of a file for
storing password keys. When the tools need additional passwords, they
will rewrite this file and invoke the user's editor for the new
passwords to be added. This allows passwords to be reused across
invocations of the signing tools, without making the user reenter them
every time.
Paranoid users can use a file stored in a ramdisk, or not use this
feature at all (the code will prompt for passwords in the ordinary way
when ANDROID_PW_FILE is not set).
The build system now (in donut) produces builds that use the testkey
cert for OTA package verification. Change the app-signing script to
also optionally substitute the "real" cert in both the recovery and
system images. Also fix bug where the build fingerprint and
description were not getting properly updated in the recovery
partition.
building images & OTA packages out of vendor/google.
