We have already switched to the protobuf format for new builds, and
the downgrade packages will require a data wipe. So it should be safe
to drop the support for text format.
This also helps to save the issue when users sideload a package with a

intended build.

The two functions check_wipe_package() and check_newer_ab_build() were
using the same flow; and checked the same device properties against the
metadata file in the package. These properties include: ota_type,
pre-device, and serial number.
Therefore, we can consolidate the checks to a single function; and
continue to check the fingerprint and timestamp only for AB updates.
This change also addresses the need to accept multiple serial number in
the wipe package.

We used to convert a pem certificate file to some intermediate plain

uncessary since the x509.pem can be directly parsed with openssl

The update_verifier now compares the fingerprint of a partition before
performing the blocks read. If the fingerprint of the current system property
mismatches the one embedded in the care_map, verification of this partition
will be skipped. This is useful for the possible system only updates in the
future.

Change-Id: Iea309148a05109b5810dfb533d94260d77ab8540
The refactor separates out the parsing of care_map and the actual
verification of the partitions. Moreover, it skips the verification in case
of a format error in the care map.
Also, the parsing of care_map now uses the suffix of the file to
tell if it has the protobuf format or the plain text format.

applypatch() was initially designed for file-based OTA, operating on
individual files. It was later extended to allow patching eMMC targets
as a whole, in favor of block-based updates.
As we have deprecated file-based OTA since Oreo, part of the code in
applypatch() has become obsolete. This CL refactors the related
functions, by removing the obsolete logic and focusing on eMMC targets.
Since this CL substantially changes applypatch APIs, it adds new
functions to avoid unintentionally mixing them together. In particular,
it removes `applypatch()`, `applypatch_check()`, `applypatch_flash()`,
and adds `PatchPartition()`, `PatchPartitionCheck()`, `FlashPartition()`
and `CheckPartition()`. It also replaces the old Edify functions
`apply_patch()` and `apply_patch_check()` with `patch_partition()` and
`patch_partition_check()` respectively.
This CL requires matching changes to OTA generation script (in the same
topic).

This applies to the standalone applypatch executable
(/system/bin/applypatch on device). This executable is only used when
installing (via patching or flashing) a recovery image on non-A/B
device.
This CL removes the support for patching non-eMMC targets from
applypatch that has been deprecated as part of file-based OTA. For
patching eMMC targets, it also drops the support for accepting multiple
patches (not useful, since the source file must be fixed).
This CL needs the matching change in the same topic, which writes the
script of "/system/bin/install-recovery.sh". Note that this CL doesn't
chanage the applypatch API signatures, in order to minimize the CL size.
*BEFORE*
usage: /system/bin/applypatch [-b <bonus-file>] <src-file> <tgt-file> <tgt-sha1> <tgt-size> [<src-sha1>:<patch> ...]

Also fix an error-pone behavior in previous code when verifying an eMMC
target. As long as it loads the partition content successfully according
to the SHAs embedded in the filename, it shouldn't further check against
the SHAs given in the second argument. Because the loaded contents
relate to a specific partition size.
For example:
apply_patch_check(
"EMMC:/boot.img:src_size:src_hash:tgt_size:tgt_hash",
"src_hash");
Assume "/boot.img" already has the desired hash of "tgt_hash", the
previous code would give wrong verification result. The issue can be
addressed by additionally listing "tgt_hash" as one of the desired SHAs
(or by applying this CL).

The matching edify function has been removed from EdifyGenerator [1]. In
theory device-specific releasetools script may still use this function,

the contents when asserting a text file.

This is a stress test that instantiates multiple testcases that
interrupt a BBOTA update at every transfer command. Each testcase
asserts the last_command_file after the interruption, verifies the
update resumability, then resumes the update and asserts the updated
image.
The transfer list in the testcase covers most of the transfer commands
(stash/free/move/bsdiff/zero/new), as well as some special pattern like
having duplicate stash ids.
This CL also addresses one issue in the updater code, by resetting the
stash_map before each run. The stash map should be valid only per
block_image_verify/block_image_update run. Having leftover may cause
issue in subsequent runs, in particular when calling block_image_verify
after a previous run of block_image_{update,verify}.
