The new command is part of the transfer.list and allows us to compute the hash
tree on non-ab devices.
The required arguments for the hash_tree computation are:
hash_tree_ranges
source_ranges
hash_algorithm
salt_hex
root_hash
Bug: 25170618
Test: unit tests pass; run simulator with compute_hash_tree

The getopt_long(3) implementation in Android (upstream freebsd) expects
a null-terminated array while parsing long options with required args.
if (long_options[match].has_arg == required_argument) {
optarg = nargv[optind++];
}
...
if (long_options[match].has_arg == required_argument && optarg == NULL) {
return (BADARG);
}
This seems to make sense in practice, as getopt(3) takes the first two
arguments of argc and argv that are "as passed to the main() function on
program invocation", and both of C and C++ spec say "the value of
argv[argc] shall be 0".
Prior to the CL, we may run into undefined behavior on malformed input
command line (e.g. missing arg for an option that requires one). This CL
fixes the issue by always appending a nullptr to the argument list (but
without counting that into argc).

This shortens the gap between A/B and non-A/B builds, by replacing the
dependency on build-time flag with runtime detection instead. It also
allows building and testing both paths regardless of the target OTA
type.
The size increase to /sbin/recovery looks negligible (< 0.01%).
- marlin: increased from 2084928 to 2085024;
- angler: increased from 2084776 to 2084896.
Test: Run recovery_component_test on angler and marlin.
Test: Sideload an A/B OTA package on marlin.
Test: Sideload a non-A/B OTA package on angler.

In order to support that, this CL adds Paths::set_resource_dir() to
override the default resource dir ("/res/images/") that's only available
under recovery. Note that since there're external modules depending on
libminui, it adds a separate function of res_set_resource_dir(), instead
of requiring the dependency on libotautil for everyone.
Test: mmma -j bootable/recovery
Test: Run recovery_unit_test on marlin.

This breaks the dependency on common.h (which belongs to
recovery/librecovery) from librecovery_ui. reboot() is now owned by
libotautil, which is expected to be a leaf node to be depended on.
With the change, recovery and updater also share the same reboot() code
now.

from libupdater / updater.

We have a general need for overriding more paths (e.g. "/tmp"), mostly
for testing purpose. Rename CacheLocation to Paths, and use that to
manage TEMPORARY_{INSTALL,LOG}_FILE.

We set the limit of the max stash size to 80% of cache size. But the
cache space can still be insufficient for the update if the log files
occupy a large chunk of /cache. So remove the old logs for now to make
room for the update.

Otherwise the applypatch executable will fail to back up the source

This class allows us to set the following locations dynamically:
cache_temp_source, last_command_file, stash_directory_base.
In the updater's main function, we reset the values of these variables
to their default locations in /cache; while we can set them to temp
files in unit tests or host simulation.
Test: unit tests pass

Prior to this CL, the block verification works were assigned based on
the pattern of the ranges, which could lead to unbalanced workloads. This
CL adds RangeSet::Split() and moves update_verifier over.
a) For the following care_map.txt on walleye:
system
20,0,347,348,540,556,32770,33084,98306,98620,163842,164156,229378,229692,294914,295228,524289,524291,524292,524348,529059
vendor
8,0,120,135,32770,32831,94564,98304,98306
Measured the time costs prior to and with this CL with the following
script.
$ cat test_update_verifier.sh
#!/bin/sh
adb shell stop
adb shell "cp /data/local/tmp/care_map.txt /data/ota_package/"
for i in $(seq 1 50)
do
echo "Iteration: $i"
adb shell "bootctl set-active-boot-slot 0"
adb shell "echo 3 > /proc/sys/vm/drop_caches"
adb shell "time /data/local/tmp/update_verifier"
sleep 3
done
Without this CL, the average time cost is 5.66s, while with the CL it's
reduced to 3.2s.
b) For the following care_map.txt, measured the performance on marlin:
system
18,0,271,286,457,8350,32770,33022,98306,98558,163842,164094,196609,204800,229378,229630,294914,295166,501547
vendor
10,0,42,44,85,2408,32770,32806,32807,36902,74242
It takes 12.9s and 5.6s without and with the CL respectively.
Fixes: 68553827
Test: recovery_unit_test
Test: Flash new build and trigger update_verifier. Check the balanced
block verification.

We used to CHECK and abort on parsing errors. While it works fine for
the updater use case (because recovery starts updater in a forked
process and collects the process exit code), it's difficult for other
clients to use RangeSet as a library (e.g. update_verifier).
This CL switches the aborts to returning empty RangeSet instead. Callers
need to check the parsing results explicitly.
The CL also separates RangeSet::PushBack() into a function, and moves
SortedRangeSet::Clear() into RangeSet.
Test: recovery_unit_test
Test: Sideload an OTA package with the new updater on angler.
Test: Sideload an OTA package with injected range string errors. The
updater aborts from the explicit checks.

Since it has grown much larger, users of the header shouldn't compile
and carry their full copies.
Also add missing header includes in imgdiff.cpp and imgdiff_test.cpp.

This reverts commit 26436d6d6010d5323349af7e119ff8f34f85c40c to re-land
"Move error_code.h into otautil.".
This way it stops requiring relative path ".." in LOCAL_C_INCLUDES
(uncrypt and edify). Soong doesn't accept non-local ".." in
"local_include_dirs".
This CL needs to land with device-specific module changes (e.g. adding
the dependency on libotautil).
