* libsparse: Fix overflow of merged sparse chunk lengthHyeongseok Kim2020-08-111-4/+4
| | | | | | | | | | | | Merging sparse chunk can make sparse map block bigger than 4GiB, that can't be covered by unsigned integer type. Fix this by changing unsigned int to uint64_t type. Test: sparse build Bug: 162808120 Change-Id: Id4d3f88f9d531c25c3937c99b2c81efb915605ee Signed-off-by: Hyeongseok Kim <hyeongseok@gmail.com> Cc: hyeongseok.kim <hyeongseok.kim@lge.com>

* libsparse: Add sparse typed callbackJerry Zhang2018-07-251-7/+30
| | | | | | | | | | | | | | | | Currently, sparse_file_callback uses libsparse's own logic for reading a file into a buffer. However, a caller may want to use their own logic for doing this in order to customize the buffer size and parallelize the reads/writes. Also, a caller may want to implement fill blocks with their own logic as well. To do this add sparse_file_typed_callback which calls a different callback function depending on the type of the sparse chunk being written. Test: Use typed callback for fd writes Bug: 78793464 Change-Id: I75955a464fc05991f806339830fdfa05fda354b9
