Setting 'uses_shared_blocks' indicates that the block list for a given
file is incomplete, as some of the blocks are "owned" by others. As a
result, such a file will be skipped from imgdiff'ing.
This CL makes a copy of the original block list before removing the
shared blocks. It uses the original RangeSet as the value of
extra['uses_shared_blocks']. validate_target_files.py will try to read
the file as in the original RangeSet, unless the original list is also
incomplete or has non-monotonic ranges.
Test: Run validate_target_files on a target that uses
`BOARD_EXT4_SHARE_DUP_BLOCKS := true`.

Pages in .data.rel.ro are always dirty. Move whatever we can to
.rodata so that we reduce memory pressure.
The size of rodata, text, and data.rel.ro sections of libc on cuttlefish

rodata: 0xfd70 -> 0x101d0 (+1120 bytes)
text: 0xb5715 -> 0xb56e5 (-48 bytes)
data.rel.ro: 0x57e0 -> 0x5230 (-1456 bytes)

To more quickly settle on a no free space result, recognize that
there is roughly 1/58.5 overhead managing the free space pool as
determined experimentally. This algorithm carries with it some
risk of being sensitive to any alterations in ext4.
This also addresses the issue of a much larger apparent free space
available calculated on the sample pass when deploying ext4 dedupe,
and resolves the poorer estimation that happens without accounting
for the overhead.
The alternative of adding a second pass works to a similar, and
likely more comforting algorithm and result. But doing so adds
a minute to the typical incremental build time, or +50% to the
time it takes to determine ext4 right sized images.

The image building functions in build_image.py have been returning
(success, result) or special values to indicate the validity of the
result. The same logic can be better expressed by raising exceptions
instead, because
a) using a special value relies on caller to check for that magic
value;
b) exceptions can carry additional messages other than a boolean does,
e.g. the output from the failing command;
c) caller can have cleaner code flow without explicitly checking for
the validity of the result.
This CL changes such functions to raise on errors. The majority of these
functions are internal to build_image.py only, except for BuildImage()

When AVB is enabled with PRODUCT_USE_DYNAMIC_PARTITION_SIZE, AVB
metadata (e.g., hash tree, fec metadata) will consume _RESERVED_SIZE,
resulting in smaller reserved size in file system (e.g., ext4).

for file system. This is done by adding a function to binary search an
optimal partition size for a given image size (disk usage + _RESERVED_SIZE).

Unless using dynamic partitions, `partition_size` should be a fixed
value that equals to the partition size in BoardConfig. It should stay
the same when building an image for that partition. Only the actual
image size that's used to hold the filesystem could be adjusted. This CL
cleans up the uses of `partition_size` and `image_size` to better
reflect such logic.
With dynamic partitions, the only thing that changes is the need to
compute `partition_size` upfront. Once that's done, `partition_size`
should remain unchanged.

This adds a set of standard build properties that are shared
between the system, vendor, odm, product, product_services and
bootimage partitions. The following properties are added:
ro.X.build.date
ro.X.build.date.utc
ro.X.build.fingerprint
ro.X.build.id
ro.X.build.tags
ro.X.build.type
ro.X.build.version.incremental
ro.X.build.version.release
ro.X.build.version.sdk
ro.product.X.brand
ro.product.X.device
ro.product.X.manufacturer
ro.product.X.model
ro.product.X.name
vendor and odm already had all of these, but bootimage, product
and product_services only had a subset and system didn't have
any.

Otherwise it gives a floating-point value (i.e. 1230768000.0). e2fsdroid
(i.e. the user of the value) didn't complain though, because it calls
strtoul(3) without checking endptr.

The recovery image will be packed under BOOT/RAMDISK only if
system_root_image and recovery_as_boot both are true (e.g. non-A/B
devices launched since P).

The change in [1] moved the recovery etc files from /etc to /system/etc.
However, we may use the latest OTA tools to build incremental OTAs for
old target_files zips. This CL adds a workaround to look at both of the
old and new locations.
[1] commit 696bb33676
Bug: 113073663
Test: Build a previously failing incremental OTA for taimen.
Change-Id: Ie07aa1713e616d523838b1260a992b20f5a11612
When the update package gets larger than 2 GiB, payload.bin offset
mentioned in metadata file for ota-streaming-property-files gets
shifted (CrAU of payload.bin) because ZipInfo FileHeader() returns
incorrect value. To solve the issue, offset is re-calculated from
fixed bytes of central directory file header, filename length and
extra length.
This patch is to sync with update_device.py script.
Test: manually create an A/B update package and run it using
update_device.py

They used to be installed under recovery/root/etc. This CL moves the
files to the new location and creates a symlink from /etc to /system/etc
(done by the rule in system/core/rootdir). This gives similar layout
between normal boot and recovery, and allows installing prebuilt_etc
files with Soong (`recovery_available: true`).
As part of the change, we no longer need the whitelisting rule for
mke2fs.conf.
Bug: 112780007
Test: Build with other changes in the topic (aosp_taimen-userdebug).
Check the generated files under recovery (/etc being a symlink to
/system/etc).
Test: Boot into recovery. Verify basic functionalities (`adb shell` and
`adb sideload`, factory reset).

When trying to support sparse format for GSIs, aosp/720949, a bug in
e2fsck was triggered, and hence failed the build for sparse GSI.
This workaround disables the detection of ASAN ODR so we can build
sparse GSIs successfully like we previously did for the vendors,
some of which can't handle unsparse images.

The add_img_to_target_files.py script uses upper() to determine
the name of sub-directory under target_files_intermediates. The
name of the image is product-services.img but the sub-directory
name was PRODUCT_SERVICES. Change it to PRODUCT-SERVICES so that
'm dist' works.

The usage of datetime.fromtimestamp previously resulted in the build or
signing machine's local timezone affecting the Unix timestamp ultimately
applied to images generated by add_img_to_target_files. The go/ab build
outputs would use 2009-01-01 00:00 UTC, for example, but local builds
and the release signed images (generated through go/ab-sign) would use
2009-01-01 00:00 PST. This change makes the timestamps always use UTC.

Split the flag into PRODUCT_USE_DYNAMIC_PARTITION_SIZE
and PRODUCT_BUILD_SUPER_PARTITION. More sub-flags can be
added with the same way.
Also change some checks with USE_LOGICAL_PARTITIONS with
the appropriate sub-flags.
This allows easier device bring-up to fulfill the requirements
separately.
This also enables dynamic partition size without logical patition.
Originally, to enable BOARD_*_PARTITION_RESERVED_SIZE must also
enable PRODUCT_USE_LOGICAL_PARTITIONS. The patch fix the rule to
let dynamic partition size is able to be used independently.

When building a system image with system_root_image enabled, the size
computation should include files under both of in_dir (i.e. /system
files) and root (pointed by 'root_dir'). Because files from both
locations will end up into the built image. The files under root are
usually only a few MiBs, but should be accounted for especially in the
context of logical partitions (where the partition size will be
allocated based on the actual need). Note that we will still need some
"reserved space" (defined via BOARD_*_PARTITION_RESERVED_SIZE) to cover
the cost for filesystem and/or verity metadata.
This CL moves the combination of the two dirs up, before parsing and
computing other properties. This doesn't affect anything for a
successful image building path. It may however increase the time to
error out in certain error path, since it copies the files earlier now.
Test: python -m unittest test_build_image
Test: `make dist`
Test: Setup a target with PRODUCT_USE_LOGICAL_PARTITIONS == true and
BOARD_SYSTEMIMAGE_PARTITION_RESERVED_SIZE == 20MiB. Build system
image successfully.
Test: Setup a target with PRODUCT_USE_LOGICAL_PARTITIONS == true and
BOARD_SYSTEMIMAGE_PARTITION_RESERVED_SIZE == 20MiB. Write a large
file to root dir (PRODUCT_OUT_ROOT). The image building fails, but
reporting a size that accounts for both of /system and root.
Change-Id: Idfb26b8e259626ba57ec3bd4f85d357c30e56163
When verity is enabled, `partition_size` has the "adjusted" partition
size for holding the filesystem files (i.e. excluding verity hashtree,
and FEC metadata if applicable), whereas `original_partition_size` has
the one for the actual image returned by build_image.py.
`partition_size` must be smaller than `original_partition_size`. As a
result, the later assertion in Makefile (e.g. assert-max-image-size) may
fail to hold when using `partition_size`.
This CL addresses the issue by returning the value in
`original_partition_size` instead, if available. It also changes to
include both values when dumping the size info on image creation
failure.
Fixes: 79106666
Test: `m dist` with aosp_walleye-userdebug
Test: Set up walleye to use logical partitions, with a reserved size of

For example, verify a target_files.zip that has system AVB-signed as a
chained partition.

signed-target_files-4904652.zip \
--verity_key verifiedboot_pub.pem \
--avb_system_key_path system_pub.pem
Note that verifiedboot_pub.pem should be the key (either public or
private) to verify vbmeta.img, and 'system_pub.pem' should be the key
(either public or private) for the chained partition of system.
testdata/testkey.key is the private key converted from
testdata/testkey.pk8 for testing purpose (`openssl pkcs8 -in
testdata/testkey.pk8 -inform DER -out testdata/testkey.key -nocrypt`).
