* Redundant checking of STL container elementMikhail Lappo2017-03-231-3/+1
| | | | | | | | As of C++ specification size_type erase( const key_type& key ); removes the element (if one exists). There is no need to perform the check twice. Change-Id: I4b057c08526abc7c2a483a60f9e166e4d8f56a74

* Fix the permission of stashed blocks created by updaterTianjie Xu2017-03-221-0/+12
| | | | | | | | | | | Our updater created the stashes with root permission. This causes an access denial when the RecoverySystem service tries to clean up these blocks after a failing update. As a result, the subsequent OTA updates may fail due to insufficient cache space. Bug: 36457133 Test: stashed blocks cleaned successfully after reboot Change-Id: If0ca99638cdfa1033646f29d9cc92b5ff1bacac1

| | | | | | | | | | This reverts commit bb0cd75a0e1f6760bdf96bd141f3a546ffa45fbc. Broke the 'free' command that deletes a stash. Bug: 36242722 Test: The previously failed incremental applies successfully. Change-Id: I1237cb0a33adfbeea57e0465b629704862ba13aa
* Print SHA-1 in hex for corrupted blocksTianjie Xu2017-03-131-3/+140
| | | | | | | | | | | It will be helpful for debug if we know which blocks are corrupted after a verification failure. This CL prints the SHA-1 for each source block in a transfer command if these blocks don't have an expected hash. And along with the correct SHA-1, we will catch the corrupted blocks. Bug: 21124445 Test: Printed the mismatched SHA-1 for bullhead during an update. Change-Id: I683d4bdaf9a335035045b3f532b3a265b2fcbbfc

| * Skip stashing source blocks in verify modeTianjie Xu2016-03-231-8/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently block_image_verify() stashes source blocks to /cache and in some case triggers I/O errors. To avoid this risk, We create a map from the hash value to the source blocks' range_set. When executing stash command in verify mode, source range is saved but block contents aren't stashed. And load_stash could get its value from either the stashed file from the previous update, or the contents on the source partition specified by the saved range.

However, we were using memset(3) to zero out the struct, which effectively assigned unique_fd(0) to fd. When it called fd.reset(), file descriptor 0 was unintentionally closed. When FD 0 was later reassigned via open(2), it led to lseek(2) errors: "Bad file descriptor". This CL switches to using braced-init (i.e. '= {}') instead, so that the default constructor unique_fd(-1) would be called.
