2016-10-18Replace minzip with libziparchiveTianjie Xu1-47/+26
Clean up the duplicated codes that handle the zip files in bootable/recovery; and rename the library of the remaining utility functions to libotautil. Test: Update package installed successfully on angler. Bug: 19472796 Change-Id: Iea8962fcf3004473cb0322b6bb3a9ea3ca7f679e

2016-10-11Refactor libupdater into a seperate module.Tao Bao1-2/+2
So that we can write native tests for updater functions. This CL adds a testcase for getprop() function. Test: mmma bootable/recovery; Run recovery_component_test on device. Change-Id: Iff4c1ff63c5c71aded2f9686fed6b71cc298c228
2016-09-01Check an edge case when read(2) returns 0Tianjie Xu1-0/+4
We might end up in an infinite loop if read(2) reached EOF unexpectedly. The problematic code in uncrypt mentioned in the bug has been fixed by switching to libbase ReadFully(). So I grepped through the recovery code and fixed some other occurences of the issue. Bug: 31073201 Change-Id: Ib867029158ba23363b8f85d61c25058a635c5a6b

2016-04-27updater: Don't zero out CommandParameters with memset(3).Tao Bao1-2/+1
[1] switched a few things to android::base::unique_fd including CommandParameters.fd. 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.

2016-03-25Skip stashing source blocks in verify modeTianjie Xu1-8/+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.

When automatically stashing overlapping blocks, should the stash file already exist due to an explicit stash command, it's not safe to remove the stash file after the command has completed. Note that it is safe to assume that the stash file will remain in place during the execution of the next command, so we don't have take other measures to preserve overlapping blocks. The stash file itself will be removed by a free command when it's no longer needed. Bug: 20297065 Change-Id: I8ff1a798b94086adff183c5aac03260eb947ae2c

2015-01-30Support resuming block based OTAsSami Tolvanen1-346/+1460
Add support for transfer list version 3, which allows us to verify the status of each command and resume an interrupted block based OTA update. Notes on the changes: - Move the previous BlockImageUpdateFn to a shorter and reusable PerformBlockImageUpdate, which can be used also in BlockImageVerifyFn for verification. - Split individual transfer list commands into separate functions with unified parameters for clarity, and use a hash table to locate them during execution. - Move common block reading and writing to ReadBlocks and WriteBlocks to reduce code duplication, and rename the readblock and writeblock to less confusing read_all and write_all. The coding style of the new functions follows the existing style in the updater/edify code.

2014-09-26support for version 2 of block image diffsDoug Zongker1-45/+209
In version 2 of block image diffs, we support a new command to load data from the image and store it in the "stash table" and then subsequently use entries in the stash table to fill in missing bits of source data we're not allowed to read when doing move/bsdiff/imgdiff commands. This leads to smaller update packages because we can break cycles in the ordering of how pieces are updated by storing data away and using it later, rather than not using the data as input to the patch system at all. This comes at the cost of the RAM or scratch disk needed to store the data. The implementation is backwards compatible; it can still handle the existing version 1 of the transfer file format.
