Therefore, libinstall becomes the sole owner to handle the request from minadbd service. The change also includes 1. move logging.cpp out of librecovery 2. drop the dependency on common.h 3. now it's more sensible to move the wipe_cache as part of install_package. move the wipe_cache to the end of the function. Bug: 130166585 Test: wipe data and cache from menu Change-Id: I6f356dccdb38015c50acf756bac246f87c30fc1f

// Strictly to deal with reboot into system after OTA, then
|
|
// reboot while in system before boot complete landing us back
|
|
// into recovery to continue with any mitigations with retained
|
|
// log history. This simply refreshes the pmsg files from
|
|
// the last pmsg file contents.
|
|
//
|
|
// Usage:
|
|
// recovery-refresh [--force-rotate|--rotate]
|
|
//
|
|
// All file content representing in the recovery/ directory stored in
|
|
// /sys/fs/pstore/pmsg-ramoops-0 in logger format that reside in the
|
|
// LOG_ID_SYSTEM buffer at ANDROID_LOG_INFO priority or higher is
|
|
// refreshed into /dev/pmsg0. This ensures that an unexpected reboot
|
|
// before recovery-persist is run will still contain the associated
|
|
// pmsg Android Logger content.
|
|
//
|
|
// --force-rotate recovery/last_kmsg and recovery.last_log files are
|
|
// rotated with .<number> suffixes upwards.
|
|
// --rotate rotated only if rocovery/last_msg or recovery/last_log
|
|
// exist, otherwise perform 1:1 refresh.
