* Save the target file when applypatch tests failTianjie Xu2018-04-271-0/+8
| | | | | | | | | | | | | Save the target file to tempfile upon unittest failures so that we can try to decompress the deflate chunks in the flaky unittests. And print the zlib version in case that gets changed. Also the SHA1 of the uncompressed data seems correct; so only keep the final SHA1 to double confirm. Bug: 67849209 Test: recovery_component_test Change-Id: Ic6447c2b75c29379d6844cd23a0ff1c4305694a0
* Rename CacheLocation to Paths.Tao Bao2018-04-261-5/+5
| | | | | | | | | | 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. Test: mmma -j bootable/recovery Test: recovery_component_test Change-Id: Ia8ce8e5695df37ca434f13ac4d3206de1e8e9396
* Dump debug information for apply_patch unit testsTianjie Xu2018-04-241-0/+5
| | | | | | | | | | | | | The apply patch test should have a deterministic way to append patch data. Add debug logs to dump the length and SHA1 of each step to further track down the flakiness. Also redirect the debug logging to stdout in case the logcat becomes too chatty. Bug: 67849209 Test: Run recovery_component_test Change-Id: I42bafef2d9dee599719ae57840b3d8c00d243ebd
* applypatch: Drop the SHA_CTX parameter in Apply{BSDiff,Image}Patch.Tao Bao2018-04-201-8/+7
| | | | | | | | | | As they're accepting the SinkFn callback, it makes more sense to leave the work to their callers. Test: mmma -j bootable/recovery Test: Run recovery_component_test on marlin. Test: No other active user of the two functions. Change-Id: I8d67b38ce037925442296f136b483e0c71983777
* applypatch: Dump patch info on mismatching patching result.Tao Bao2018-04-191-1/+16
| | | | | | | | | | | | After splitting the previously flaky ApplyPatchModesTest#PatchModeEmmcTarget tests, PatchModeEmmcTargetWithMultiplePatches now becomes the sole victim. This CL dumps additional info to narrow down the cause. Bug: 67849209 Test: `recovery_component_test` on marlin. Test: It dumps additional info after using corrupt bonus.file. Change-Id: Ic5436de457cc882a51d03f49d5cee70077f7d3df
* Remove the old log files if cache space is insufficient for OTATianjie Xu2018-04-131-7/+7
| | | | | | | | | | | 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. Bug: 77528881 Test: unit tests pass Change-Id: Ia8bcb0ace11f8164ad9290bfb360e08e31d282cb
* Add a singleton CacheLocation to replace the hard coded locationsTianjie Xu2018-02-281-6/+5
| | | | | | | | | | | | 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 Change-Id: I528652650caa41373617ab055d41b1f1a4ec0f87
* Skip the cache size check on hostTianjie Xu2018-02-131-3/+2
| | | | | | | | | | | When running the update simulation, we choose to skip the cache size check for now due to the lack of "/cache" on host. And in later cls we can implement a cache size estimator to make the check more constrained. Also build the host version of support libraries. Test: unit test pass Change-Id: I3ed93c857fd02f7b62f5baba9130f75c3236e717
* applypatch: Remove the 'st' field from FileContents.Tao Bao2017-12-071-15/+3
| | | | | | | | It used to keep track of the stat(2) info (e.g. st_mode/st_gid/st_uid) while patching a file in file-based OTA. Test: Build and use the new updater to apply an update on bullhead. Change-Id: Ibf8f0f4b14298a9489bf24a2678bb279c5d9c8f3
* applypatch: Change the patch parameter to const Value& in Apply{BSDiff,Image}Patch.Tao Bao2017-11-101-4/+4
| | | | | | | It used to be "const Value*", but nullptr won't be a valid input. Test: recovery_host_test; recovery_component_test Change-Id: I904b5689ac3e64504088bf0544c9fb5d45a52243
* Switch to bionic gtest in bootable/recoveryTianjie Xu2017-11-031-9/+9
| | | | | | | | | | | | | | | | | We encountered segfaults in Imgdiff host tests due to the failure to reset states of getopt. The problem can be solved by switching to use bionic's gtest where a new process is forked for each test. Also modify the recovery_component_test to make sure it runs in parallel. Changes include: 1. Merge the writes to misc partition into one single test. 2. Change the hard coded location "/cache/saved.file" into a configurable variable. Bug: 67849209 Test: recovery tests pass Change-Id: I165d313f32b83393fb7922c5078636ac40b50bc2
* Move rangeset.h and print_sha1.h into otautil.Tao Bao2017-10-111-1/+1
| | | | | | | | | Also drop the "bootable/recovery" path in LOCAL_C_INCLUDES from applypatch modules. Test: lunch aosp_{angler,bullhead,fugu,dragon,sailfish}-userdebug; mmma bootable/recovery Change-Id: Idd602a796894f971ee4f8fa3eafe36c42d9de986

* applypatch: Let Apply{BSDiff,Image}Patch accept std::function.Tao Bao2017-03-281-14/+10
| | | | | | Test: mmma bootable/recovery system/update_engine Test: recovery_component_test Change-Id: I93c2caa87bf94a53509bb37f98f2c02bcadb6f5c
* applypatch: Change the ssize_t length parameters to size_t.Tao Bao2017-03-281-19/+18
| | | | | | | | | | | | | | | | | Mostly for applypatch family APIs like ApplyBSDiffPatch() and ApplyImagePatch(). Changing to size_t doesn't indicate they would necessarily work with very large size_t (e.g. > ssize_t), just similar to write(2). But otherwise accepting negative length doesn't make much sense. Also change the return type of SinkFn from ssize_t to size_t. Callers tell a successful sink by comparing the number of written bytes against the desired value. Negative return values like -1 are not needed. This also makes it consistent with bsdiff::bspatch interface. Test: recovery_component_test Test: Apply an incremental with the new updater. Change-Id: I7ff1615203a5c9854134f75d019e266f4ea6e714
* applypatch: Drop the support for patching non-EMMC targets.Tao Bao2017-03-161-277/+109
| | | | | | | | | | | Patching regular files is used in file-based OTA only, which has become obsolete. Bug: 35853185 Test: Apply an incremental that patches the boot.img. Test: /system/bin/install-recovery.sh works. Test: recovery_component_test passes. Change-Id: Id44e42c4bc63f2162ecc8a6df1cb528b7ae6b0a9

* Remove ota_close(int) and ota_fclose(FILE*).Tao Bao2016-11-281-2/+2
| | | | | | | | | | | We should always use unique_fd or unique_file to hold the FD or FILE* pointer when opening via ota_(f)open functions. This CL avoids accidentally closing raw FDs or FILE* pointers that are managed by unique_fd/unique_file. Test: recovery_component_test passes. Change-Id: If58eb8b5c5da507563f85efd5d56276472a1c957
* Add ota_close(unique_fd&) and ota_fclose(std::unique_ptr<FILE>&).Tao Bao2016-11-231-7/+7
| | | | | | | | | | | | | | | | | | | | | | We were using the below sequence prior to the CL in [1]. unique_fd fd(ota_open(...)); ota_close(fd); fd.reset(ota_open(...)); fd.reset() may unintentionally close the newly opened FD if it has the same value as the early ota_open. The CL in [1] changed to "ota_close(fd.release())" to avoid the issue. This CL adds a new overloaded function ota_close(unique_fd&) to handle the release automatically. Similarly add ota_fclose(std::unique_ptr<FILE>&). [1] commit 48cf770471ef53fbf0a1837196220862a0bdb18d. Bug: 33034669 Test: recovery_component_test passes. Change-Id: Ief91edc590e95a7426e33364b28754173efb1056
* applypatch: Release FD when explicitly calling close.Tao Bao2016-11-211-5/+5
| | | | | | | | | | | We use android::base::unique_fd() to avoid leaking FD. We also want to call close (or ota_close) to explicitly check the close result. When combining the two together, we need to release the unique_fd to avoid closing the same FD twice. Bug: 33034669 Test: Trigger applypatch with install-recovery.sh. Change-Id: I1a4f5d5fba7a23ef98d8bd7b7b07e87ae6f705c5
* applypatch: Use unique_fd to avoid leaking FDs.Tao Bao2016-11-171-282/+270
| | | | | | | | | Add unique_fd that calls ota_close() instead of the default closer. Test: recovery_component_test passes. Test: Apply a package that calls apply_patch(). Change-Id: I0c19921731757934f76cf7d5215916673a8f2777
* applypatch: Clean up LoadPartitionContents().Tao Bao2016-11-171-283/+257
| | | | | | | | | We don't need three vectors to sort the (size, SHA-1) pairs. Test: recovery_component_test passes. Test: Apply a package that calls apply_patch_check() to patch EMMC partitions. Change-Id: I4a6620630a6711f490822cf30f1e7fe5cea6ce49
* applypatch: Switch the parameter of Value** to std::vector.Tao Bao2016-10-291-8/+8
| | | | | | Test: Unit tests and install-recovery.sh pass on angler and dragon. Change-Id: I328e6554edca667cf850f5584ebf1ac211e3d4d1
* Fix applypatch_check failure when applying update on anglerTianjie Xu2016-10-181-1/+1
| | | | | | | | | | | Applypatch_check should be skipped if no sha is specified. As the comments said: "It's okay to specify no sha1s; the check will pass if the LoadFileContents is successful. Useful for reading partitions, where the filename encodes the sha1s." Test: The update package applied on angler successfully. Bug: 32243751 Change-Id: Ib8f3dadf19f745c2dbd350d60da46ab12d75bc87
* Change StringValue to use std::stringTianjie Xu2016-10-151-16/+12
| | | | | | | | | | | Changing the field of 'Value' in edify to std::string from char*. Meanwhile cleaning up the users of 'Value' and switching them to cpp style. Test: compontent tests passed. Bug: 31713288 Change-Id: Iec5a7d601b1e4ca40935bf1c70d325dafecec235
* Check an edge case when read(2) returns 0Tianjie Xu2016-09-011-0/+3
| | | | | | | | | | 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

* Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.Tao Bao2016-03-031-1/+1
| | | | | | | | | | | | | If two libraries both use LOCAL_WHOLE_STATIC_LIBRARIES and include a same library, there would be linking errors when generating a shared library (or executable) that depends on the two libraries both. Also clean up Android.mk files. Remove the "LOCAL_MODULE_TAGS := eng" line for the updater module. The module will then default to "optional" which won't be built until needed.
