In the split mode of imgdiff, we used to assume that the size of a split
target chunk is always greater than the blocksize i.e. 4096. This may
lead to the following assertion failure:
I0221 04:57:33.451323 818464 common.py:205 imgdiff F 02-21 04:57:33 821203 821203 imgdiff.cpp:999]
Check failed: tgt_size >= BLOCK_SIZE (tgt_size=476, BLOCK_SIZE=4096)
This CL removes the assumption and handles the edge cases.
Test: generate and verify the incremental update for TFs in the bug; unit test passes

The static analyzer complained about the function calls we were doing
here to vector::data() and vector::operator[]:
bootable/recovery/roots.cpp:193:11: warning: This function call is
prohibited after a successful vfork
Since it's not clear that vfork() is needed here, just use fork()
instead.
Bug: None
Test: Reran the static analyzer with only this patch applied. Bug
disappeared

This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.
Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.
Test: make relevant packages

The sdk_mac on build server fails with the error:
bootable/recovery/applypatch/freecache.cpp:23:10: fatal error: 'sys/statfs.h' file not found
So we will disable libapplypatch on mac.
Test: the library still builds on linux; and check the other host targets in the same cl.

When running the update simulation, we choose to skip the cache size
check for now due to the lack of "/cache" on host. And in later cls we
can implement a cache size estimator to make the check more constrained.
Also build the host version of support libraries.
Test: unit test pass

There is no logical change to the file; merely the function definition
reorder and some comestic change to make the future review easier.

When performing an update, save the index and cmdline of the current
command into the last command file if this command writes to the stash
either explicitly of implicitly. This mitigates the overhead to update
the last command file for every command. I ran a simple test on angler
and the time to update 1000 times is ~2.3 seconds.
Upon resuming an update, read the saved index first; then
1. In verification mode, check if all commands before the saved index
have already produced the expected target blocks. If not, delete the
last command file so that we will later resume the update from the
start of the transfer list.
2. In update mode, skip all commands before the saved index. Therefore,
we can avoid deleting stashes with duplicate id unintentionally;
and also speed up the update.
If an update succeeds or is unresumable, delete the last command file.
Bug: 69858743
Test: Unittest passed, apply a failed update with invalid cmd on angler
and check the last_command content, apply a failed update with invalid
source hash and last_command is deleted.

The AbortFn() used to overwrite the error message, hiding the real
failure reported in ErrorAbort(). And we will miss the failure in
the script patterns like 'blockimageupdate() || abort()'
We will ensure there's one line break at the end of ErrorAbort's
error message; and append to the existing error message when calling
abort().
Test: Message from ErrorAbort shows up in the log

The update_channel field is used to store the Omaha update channel
if update_engine is compiled with Omaha support.
We need it to be in misc to persist through factory reset.

Make update_verifier check if it runs on A/B update devices at the
beginning, and quit immediately if it doesn't, instead of re-boot.

It used to keep track of the stat(2) info (e.g. st_mode/st_gid/st_uid)
while patching a file in file-based OTA.
Test: Build and use the new updater to apply an update on bullhead.
