Split the details of generating script syntax into a generator class:
one for amend (whose output should be equivalent to the current
output), and one for edify.
Fix 'otatools' build rule to build imgdiff.
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.
Modify applypatch to be able to write MTD partitions as well as read
them. Make applypatch save a backup copy of the contents of an MTD
partition it reads in cache, to be used in case an update is
interrupted while writing back to MTD. Modify OTA package creation
script to send boot image updates in patch form.
Allow an MTD partition so serve as a source "file" in applypatch,
using a magically-formatted 'filename' that specifies the partition
name, size of data to read, and expected hash. Build incremental OTAs
that update the recovery image via a patch.
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).
All APKs that want to share a given user id must be signed with the
same key. Look inside each APK for what (if any) shared user id it
requests, and error out if any with the same shared user are being
signed with different keys.
Allow applypatch to use different filenames for the source and target.
(Using the same filename is still fine; in fact the target filename
can be specified as "-" to mean "same as the source file.) This will
allow us to still use diffs in the case of files being renamed, and
will allow us to use diffs for the boot and recovery images.
To support devphone and holiday builds we need more control over the
build fingerprint tags; generalize the -t option so we can arbitrarily
add and remove tags.
Adds the -t option to sign_target_files_apks, which lets the user
specify extra tags that should be added to the build fingerprint
during the signing process.
through the key map. Clarify the help for the -e option to
make clear this should happen.

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.
