+# Chrome OS Update Process
+
+[TOC]
+
+System updates in more modern operating systems like Chrome OS and Android are
+called A/B updates, over-the-air ([OTA]) updates, seamless updates, or simply
+auto updates. In contrast to more primitive system updates (like Windows or
+macOS) where the system is booted into a special mode to override the system
+partitions with newer updates and may take several minutes or hours, A/B updates
+have several advantages including but not limited to:
+
+* Updates maintain a workable system that remains on the disk during and after
+ an update. Hence, reducing the likelihood of corrupting a device into a
+ non-usable state. And reducing the need for flashing devices manually or at
+ repair and warranty centers, etc.
+* Updates can happen while the system is running (normally with minimum
+ overhead) without interrupting the user. The only downside for users is a
+ required reboot (or, in Chrome OS, a sign out which automatically causes a
+ reboot if an update was performed where the reboot duration is about 10
+ seconds and is no different than a normal reboot).
+* The user does not need (although they can) to request for an update. The
+ update checks happen periodically in the background.
+* If the update fails to apply, the user is not affected. The user will
+ continue on the old version of the system and the system will attempt to
+ apply the update again at a later time.
+* If the update applies correctly but fails to boot, the system will rollback
+ to the old partition and the user can still use the system as usual.
+* The user does not need to reserve enough space for the update. The system
+ has already reserved enough space in terms of two copies (A and B) of a
+ partition. The system doesn’t even need any cache space on the disk,
+ everything happens seamlessly from network to memory to the inactive
+ partitions.
+
+## Life of an A/B Update
+
+In A/B update capable systems, each partition, such as the kernel or root (or
+other artifacts like [DLC]), has two copies. We call these two copies active (A)
+and inactive (B). The system is booted into the active partition (depending on
+which copy has the higher priority at boot time) and when a new update is
+available, it is written into the inactive partition. After a successful reboot,
+the previously inactive partition becomes active and the old active partition
+becomes inactive.
+
+But everything starts with generating update payloads in (Google) servers for
+each new system image. Once the update payloads are generated, they are signed
+with specific keys and stored in a location known to an update server (Omaha).
+
+When the updater client initiates an update (either periodically or user
+initiated), it first consults different device policies to see if the update
+check is allowed. For example, device policies can prevent an update check
+during certain times of a day or they require the update check time to be
+scattered throughout the day randomly, etc.
+
+Once policies allow for the update check, the updater client sends a request to
+the update server (all this communication happens over HTTPS) and identifies its
+parameters like its Application ID, hardware ID, version, board, etc. Then if
+the update server decides to serve an update payload, it will respond with all
+the parameters needed to perform an update like the URLs to download the
+payloads, the metadata signatures, the payload size and hash, etc. The updater
+client continues communicating with the update server after different state
+changes, like reporting that it started to download the payload or it finished
+the update, or reports that the update failed with specific error codes, etc.
+
+Each payload consists of two main sections: metadata and extra data. The
+metadata is basically a list of operations that should be performed for an
+update. The extra data contains the data blobs needed by some or all of these
+operations. The updater client first downloads the metadata and
+cryptographically verifies it using the provided signatures from the update
+server’s response. Once the metadata is verified as valid, the rest of the
+payload can easily be verified cryptographically (mostly through SHA256 hashes).
+
+Next, the updater client marks the inactive partition as unbootable (because it
+needs to write the new updates into it). At this point the system cannot
+rollback to the inactive partition anymore.
+
+Then, the updater client performs the operations defined in the metadata (in the
+order they appear in the metadata) and the rest of the payload is gradually
+downloaded when these operations require their data. Once an operation is
+finished its data is discarded. This eliminates the need for caching the entire
+payload before applying it. During this process the updater client periodically
+checkpoints the last operation performed so in the event of failure or system
+shutdown, etc. it can continue from the point it missed without redoing all
+operations from the beginning.
+
+During the download, the updater client hashes the downloaded bytes and when the
+download finishes, it checks the payload signature (located at the end of the
+payload). If the signature cannot be verified, the update is rejected.
+
+After the inactive partition is updated, the entire partition is re-read, hashed
+and compared to a hash value passed in the metadata to make sure the update was
+successfully written into the partition.
+
+In the next step, the [Postinstall] process (if any) is called. The postinstall
+reconstructs the dm-verity tree hash of the ROOT partition and writes it at the
+end of the partition (after the last block of the file system). The postinstall
+can also perform any board specific or firmware update tasks necessary. If
+postinstall fails, the entire update is considered failed.
+
+Then the updater client goes into a state that identifies the update has
+completed and the user needs to reboot the system. At this point, until the user
+reboots (or signs out), the updater client will not do any more system updates
+even if newer updates are available. However, it does continue to perform
+periodic update checks so we can have statistics on the number of active devices
+in the field.
+
+After the update proved successful, the inactive partition is marked to have a
+higher priority (on a boot, a partition with higher priority is booted
+first). Once the user reboots the system, it will boot into the updated
+partition and it is marked as active. At this point, after the reboot, The
+updater client calls into the [`chromeos-setgoodkernel`] program. The program
+verifies the integrity of the system partitions using the dm-verity and marks
+the active partition as healthy. At this point the system is basically updated
+successfully.
+
+## Update Engine Daemon
+
+The `update_engine` is a single-threaded daemon process that runs all the
+times. This process is the heart of the auto updates. It runs with lower
+priorities in the background and is one of the last processes to start after a
+system boot. Different clients (like Chrome or other services) can send requests
+for update checks to the update engine. The details of how requests are passed
+to the update engine is system dependent, but in Chrome OS it is D-Bus. Look at
+the [D-Bus interface] for a list of all available methods.
+
+There are many resiliency features embedded in the update engine that makes auto
+updates robust including but not limited to:
+
+* If the update engine crashes, it will restart automatically.
+* During an active update it periodically checkpoints the state of the update
+ and if it fails to continue the update or crashes in the middle, it will
+ continue from the last checkpoint.
+* It retries failed network communication.
+* If it fails to apply a delta payload (due to bit changes on the active
+ partition) for a few times, it switches to full payload.
+
+The updater clients writes its active preferences in
+`/var/lib/update_engine/prefs`. These preferences help with tracking changes
+during the lifetime of the updater client and allows properly continuing the
+update process after failed attempts or crashes.
+
+The core update engine code base in a Chromium OS checkout is located in
+`src/aosp/system/update_engine` fetching [this repository].
+
+### Policy Management
+
+In Chrome OS, devices are allowed to accept different policies from their
+managing organizations. Some of these policies affect how/when updates should be
+performed. For example, an organization may want to scatter the update checks
+during certain times of the day so as not to interfere with normal
+business. Within the update engine daemon, [UpdateManager] has the
+responsibility of loading such policies and making different decisions based on
+them. For example, some policies may allow the act of checking for updates to
+happen, while they prevent downloading the update payload. Or some policies
+don’t allow the update check within certain time frames, etc. Anything that
+relates to the Chrome OS update policies should be contained within the
+[update_manager] directory in the source code.
+
+### Rollback vs. Enterprise Rollback
+
+Chrome OS defines a concept for Rollback: Whenever a newly updated system does
+not work as it is intended, under certain circumstances the device can be rolled
+back to a previously working version. There are two types of rollback supported
+in Chrome OS: A (legacy, original) rollback and an enterprise rollback (I know,
+naming is confusing).
+
+A normal rollback, which has existed for as long as Chrome OS had auto updater,
+is performed by switching the currently inactive partition into the active
+partition and rebooting into it. It is as simple as running a successful
+postinstall on the inactive partition, and rebooting the device. It is a feature
+used by Chrome that happens under certain circumstances. Of course rollback
+can’t happen if the inactive partition has been tampered with or has been nuked
+by the updater client to install an even newer update. Normally a rollback is
+followed by a Powerwash which clobbers the stateful partition.
+
+Enterprise rollback is a new feature added to allow enterprise users to
+downgrade the installed image to an older version. It is very similar to a
+normal system update, except that an older update payload is downloaded and
+installed. There is no direct API for entering into the enterprise rollback. It
+is managed by the enterprise device policies only.
+
+Developers should be careful when touching any rollback related feature and make
+sure they know exactly which of these two features they are trying to adapt.
+
+### Interactive vs Non-Interactive vs. Forced Updates
+
+Non-interactive updates are updates that are scheduled periodically by the
+update engine and happen in the background. Interactive updates, on the other
+hand, happen when a user specifically requests an update check (e.g. by clicking
+on “Check For Update” button in Chrome OS’s About page). Depending on the update
+server's policies, interactive updates have higher priority than non-interactive
+updates (by carrying marker hints). They may decide to not provide an update if
+they have busy server load, etc. There are other internal differences between
+these two types of updates too. For example, interactive updates try to install
+the update faster.
+
+Forced updates are similar to interactive updates (initiated by some kind of
+user action), but they can also be configured to act as non-interactive. Since
+non-interactive updates happen periodically, a forced-non-interactive update
+causes a non-interactive update at the moment of the request, not at a later
+time. We can call a forced non-interactive update with:
+
+```bash
+update_engine_client --interactive=false --check_for_update
+```
+
+### P2P Updates
+
+Many organizations might not have the external bandwidth requirements that
+system updates need for all their devices. To help with this, Chrome OS can act
+as a payload server to other client devices in the same network subnet. This is
+basically a peer-to-peer update system that allows the devices to download the
+update payloads from other devices in the network. This has to be enabled
+explicitly in the organization through device policies and specific network
+configurations to be enabled for P2P updates to work. Regardless of the location
+of update payloads, all update requests go through update servers in HTTPS.
+
+Check out the [P2P update related code] for both the server and the client side.
+
+### Network
+
+The updater client has the capability to download the payloads using Ethernet,
+WiFi, or Cellular networks depending on which one the device is connected
+to. Downloading over Cellular networks will prompt permission from the user as
+it can consume a considerable amount of data.
+
+### Logs
+
+In Chrome OS the `update_engine` logs are located in `/var/log/update_engine`
+directory. Whenever `update_engine` starts, it starts a new log file with the
+current data-time format in the log file’s name
+(`update_engine.log-DATE-TIME`). Many log files can be seen in
+`/var/log/update_engine` after a few restarts of the update engine or after the
+system reboots. The latest active log is symlinked to
+`/var/log/update_engine.log`.
+
+## Update Payload Generation
+
+The update payload generation is the process of converting a set of
+partitions/files into a format that is both understandable by the updater client
+(especially if it's a much older version) and is securely verifiable. This
+process involves breaking the input partitions into smaller components and
+compressing them in order to help with network bandwidth when downloading the
+payloads.
+
+For each generated payload, there is a corresponding properties file which
+contains the metadata information of the payload in JSON format. Normally the
+file is located in the same location as the generated payload and its file name
+is the same as the payload file name plus `.json`
+postfix. e.g. `/path/to/payload.bin` and `/path/to/payload.bin.json`. This
+properties file is necessary in order to do any kind of auto update in [`cros
+flash`], AU autotests, etc. Similarly the updater server uses this file to
+dispatch the payload properties to the updater clients.
+
+Once update payloads are generated, their original images cannot be changed
+anymore otherwise the update payloads may not be able to be applied.
+
+`delta_generator` is a tool with a wide range of options for generating
+different types of update payloads. Its code is located in
+`update_engine/payload_generator`. This directory contains all the source code
+related to mechanics of generating an update payload. None of the files in this
+directory should be included or used in any other library/executable other than
+the `delta_generator` which means this directory does not get compiled into the
+rest of the update engine tools.
+
+However, it is not recommended to use `delta_generator` directly. To manually
+generate payloads easier, [`cros_generate_update_payloads`] should be used. Most
+of the higher level policies and tools for generating payloads reside as a
+library in [`chromite/lib/paygen`]. Whenever calls to the update payload
+generation API are needed, this library should be used instead.
+
+### Update Payload File Specification
+
+Each update payload file has a specific structure defined in the table below:
+
+|Field|Size (bytes)|Type|Description|
+|-----|------------|----|-----------|
+|Magic Number|4|char[4]|Magic string "CrAU" identifying this is an update payload.|
+|Major Version|8|uint64|Payload major version number.|
+|Manifest Size|8|uint64|Manifest size in bytes.|
+|Manifest Signature Size|4|uint32|Manifest signature blob size in bytes (only in major version 2).|
+|Manifest|Varies|[DeltaArchiveManifest]|The list of operations to be performed.|
+|Manifest Signature|Varies|[Signatures]|The signature of the first five fields. There could be multiple signatures if the key has changed.|
+|Payload Data|Varies|List of raw or compressed data blobs|The list of binary blobs used by operations in the metadata.|
+|Payload Signature Size|Varies|uint64|The size of the payload signature.|
+|Payload Signature|Varies|[Signatures]|The signature of the entire payload except the metadata signature. There could be multiple signatures if the key has changed.|
+
+### Delta vs. Full Update Payloads
+
+There are two types of payload: Full and Delta. A full payload is generated
+solely from the target image (the image we want to update to) and has all the
+data necessary to update the inactive partition. Hence, full payloads can be
+quite large in size. A delta payload, on the other hand, is a differential
+update generated by comparing the source image (the active partitions) and the
+target image and producing the diffs between these two images. It is basically a
+differential update similar to applications like `diff` or `bsdiff`. Hence,
+updating the system using the delta payloads requires the system to read parts
+of the active partition in order to update the inactive partition (or
+reconstruct the target partition). The delta payloads are significantly smaller
+than the full payloads. The structure of the payload is equal for both types.
+
+Payload generation is quite resource intensive and its tools are implemented
+with high parallelism.
+
+#### Generating Full Payloads
+
+A full payload is generated by breaking the partition into 2MiB (configurable)
+chunks and either compressing them using bzip2 or XZ algorithms or keeping it as
+raw data depending on which produces smaller data. Full payloads are much larger
+in comparison to delta payloads hence require longer download time if the
+network bandwidth is limited. On the other hand, full payloads are a bit faster
+to apply because the system doesn’t need to read data from the source partition.
+
+#### Generating Delta Payloads
+
+Delta payloads are generated by looking at both the source and target images
+data on a file and metadata basis (more precisely, the file system level on each
+appropriate partition). The reason we can generate delta payloads is that Chrome
+OS partitions are read only. So with high certainty we can assume the active
+partitions on the client’s device is bit-by-bit equal to the original partitions
+generated in the image generation/signing phase. The process for generating a
+delta payload is roughly as follows:
+
+1. Find all the zero-filled blocks on the target partition and produce `ZERO`
+ operation for them. `ZERO` operation basically discards the associated
+ blocks (depending on the implementation).
+2. Find all the blocks that have not changed between the source and target
+ partitions by directly comparing one-to-one source and target blocks and
+ produce `SOURCE_COPY` operation.
+3. List all the files (and their associated blocks) in the source and target
+ partitions and remove blocks (and files) which we have already generated
+ operations for in the last two steps. Assign the remaining metadata (inodes,
+ etc) of each partition as a file.
+4. If a file is new, generate a `REPLACE`, `REPLACE_XZ`, or `REPLACE_BZ`
+ operation for its data blocks depending on which one generates a smaller
+ data blob.
+5. For each other file, compare the source and target blocks and produce a
+ `SOURCE_BSDIFF` or `PUFFDIFF` operation depending on which one generates a
+ smaller data blob. These two operations produce binary diffs between a
+ source and target data blob. (Look at [bsdiff] and [puffin] for details of
+ such binary differential programs!)
+6. Sort the operations based on their target partitions’ block offset.
+7. Optionally merge same or similar operations next to each other into larger
+ operations for better efficiency and potentially smaller payloads.
+
+Full payloads can only contain `REPLACE`, `REPLACE_BZ`, and `REPLACE_XZ`
+operations. Delta payloads can contain any operations.
+
+### Major and Minor versions
+
+The major and minor versions specify the update payload file format and the
+capability of the updater client to accept certain types of update payloads
+respectively. These numbers are [hard coded] in the updater client.
+
+Major version is basically the update payload file version specified in the
+[update payload file specification] above (second field). Each updater client
+supports a range of major versions. Currently, there are only two major
+versions: 1, and 2. And both Chrome OS and Android are on major version 2 (major
+version 1 is being deprecated). Whenever there are new additions that cannot be
+fitted in the [Manifest protobuf], we need to uprev the major version. Upreving
+major version should be done with utmost care because older clients do not know
+how to handle the newer versions. Any major version uprev in Chrome OS should be
+associated with a GoldenEye stepping stone.
+
+Minor version defines the capability of the updater client to accept certain
+operations or perform certain actions. Each updater client supports a range of
+minor versions. For example, the updater client with minor version 4 (or less)
+does not know how to handle a `PUFFDIFF` operation. So when generating a delta
+payload for an image which has an updater client with minor version 4 (or less)
+we cannot produce PUFFDIFF operation for it. The payload generation process
+looks at the source image’s minor version to decide the type of operations it
+supports and only a payload that confirms to those restrictions. Similarly, if
+there is a bug in a client with a specific minor version, an uprev in the minor
+version helps with avoiding to generate payloads that cause that bug to
+manifest. However, upreving minor versions is quite expensive too in terms of
+maintainability and it can be error prone. So one should practice caution when
+making such a change.
+
+Minor versions are irrelevant in full payloads. Full payloads should always be
+able to be applied for very old clients. The reason is that the updater clients
+may not send their current version, so if we had different types of full
+payloads, we would not have known which version to serve to the client.
+
+### Signed vs Unsigned Payloads
+
+Update payloads can be signed (with private/public key pairs) for use in
+production or be kept unsigned for use in testing. Tools like `delta_generator`
+help with generating metadata and payload hashes or signing the payloads given
+private keys.
+
+## update_payload Scripts
+
+[update_payload] contains a set of python scripts used mostly to validate
+payload generation and application. We normally test the update payloads using
+an actual device (live tests). [`brillo_update_payload`] script can be used to
+generate and test applying of a payload on a host device machine. These tests
+can be viewed as dynamic tests without the need for an actual device. Other
+`update_payload` scripts (like [`check_update_payload`]) can be used to
+statically check that a payload is in the correct state and its application
+works correctly. These scripts actually apply the payload statically without
+running the code in payload_consumer.
+
+## Postinstall
+
+[Postinstall] is a process called after the updater client writes the new image
+artifacts to the inactive partitions. One of postinstall's main responsibilities
+is to recreate the dm-verity tree hash at the end of the root partition. Among
+other things, it installs new firmware updates or any board specific
+processes. Postinstall runs in separate chroot inside the newly installed
+partition. So it is quite separated from the rest of the active running
+system. Anything that needs to be done after an update and before the device is
+rebooted, should be implemented inside the postinstall.
+
+## Building Update Engine
+
+You can build `update_engine` the same as other platform applications:
+
+```bash
+(chroot) $ emerge-${BOARD} update_engine
+```
+or to build without the source copy:
+
+```bash
+(chroot) $ cros_workon_make --board=${BOARD} update_engine
+```
+
+After a change in the `update_engine` daemon, either build an image and install
+the image on the device using cros flash, etc. or use `cros deploy` to only
+install the `update_engine` service on the device:
+
+```bash
+(chroot) $ cros deploy update_engine
+```
+
+You need to restart the `update_engine` daemon in order to see the affected
+changes:
+
+```bash
+# SSH into the device.
+restart update-engine # with a dash not underscore.
+```
+
+Other payload generation tools like `delta_generator` are board agnostic and
+only available in the SDK. So in order to make any changes to the
+`delta_generator`, you should build the SDK:
+
+```bash
+# Do it only once to start building the 9999 ebuild from ToT.
+(chroot) $ cros_workon --host start update_engine
+
+(chroot) $ sudo emerge update_engine
+```
+
+If you make any changes to the D-Bus interface make sure `system_api`,
+`update_engine-client`, and `update_engine` packages are marked to build from
+9999 ebuild and then build both packages in that order:
+
+```bash
+(chroot) $ emerge-${BOARD} system_api update_engine-client update_engine
+```
+
+If you make any changes to [`update_engine` protobufs] in the `system_api`,
+build the `system_api` package first.
+
+## Running Unit Tests
+
+[Running unit tests similar to other platforms]:
+
+```bash
+(chroot) $ FEATURES=test emerge-<board> update_engine
+```
+
+or
+
+```bash
+(chroot) $ cros_workon_make --board=<board> --test update_engine
+```
+
+or
+
+```bash
+(chroot) $ cros_run_unit_tests --board ${BOARD} --packages update_engine
+```
+
+The above commands run all the unit tests, but `update_engine` package is quite
+large and it takes a long time to run all the unit tests. To run all unit tests
+in a test class run:
+
+```bash
+(chroot) $ FEATURES=test \
+ P2_TEST_FILTER="*OmahaRequestActionTest.*-*RunAsRoot*" \
+ emerge-amd64-generic update_engine
+```
+
+To run one exact unit test fixture (e.g. `MultiAppUpdateTest`), run:
+
+```bash
+(chroot) $ FEATURES=test \
+ P2_TEST_FILTER="*OmahaRequestActionTest.MultiAppUpdateTest-*RunAsRoot*" \
+ emerge-amd64-generic update_engine
+```
+
+To run `update_payload` unit tests enter `update_engine/scripts` directory and
+run the desired `unittest.p`y files.
+
+## Initiating a Configured Update
+
+There are different methods to initiate an update:
+
+* Click on the “Check For Update” button in setting’s About page. There is no
+ way to configure this way of update check.
+* Use the [`update_engine_client`] program. There are a few configurations you
+ can do.
+* Call `autest` in the crosh. Mainly used by the QA team and is not intended
+ to be used by any other team.
+* Use [`cros flash`]. It internally uses the update_engine to flash a device
+ with a given image.
+* Run one of many auto update autotests.
+* Start a [Dev Server] on your host machine and send a specific HTTP request
+ (look at `cros_au` API in the Dev Server code), that has the information
+ like the IP address of your Chromebook and where the update payloads are
+ located to the Dev Server to start an update on your device (**Warning:**
+ complicated to do, not recommended).
+
+`update_engine_client` is a client application that can help initiate an update
+or get more information about the status of the updater client. It has several
+options like initiating an interactive vs. non-interactive update, changing
+channels, getting the current status of update process, doing a rollback,
+changing the Omaha URL to download the payload (the most important one), etc.
+
+`update_engine` daemon reads the `/etc/lsb-release` file on the device to
+identify different update parameters like the updater server (Omaha) URL, the
+current channel, etc. However, to override any of these parameters, create the
+file `/mnt/stateful_partition/etc/lsb-release` with desired customized
+parameters. For example, this can be used to point to a developer version of the
+update server and allow the update_engine to schedule a periodic update from
+that specific server.
+
+If you have some changes in the protocol that communicates with Omaha, but you
+don’t have those changes in the update server, or you have some specific
+payloads that do not exist on the production update server you can use
+[Nebraska] to help with doing an update.
+
+## Note to Developers and Maintainers
+
+When changing the update engine source code be extra careful about these things:
+
+### Do NOT Break Backward Compatibility
+
+At each release cycle we should be able to generate full and delta payloads that
+can correctly be applied to older devices that run older versions of the update
+engine client. So for example, removing or not passing arguments in the metadata
+proto file might break older clients. Or passing operations that are not
+understood in older clients will break them. Whenever changing anything in the
+payload generation process, ask yourself this question: Would it work on older
+clients? If not, do I need to control it with minor versions or any other means.
+
+Especially regarding enterprise rollback, a newer updater client should be able
+to accept an older update payload. Normally this happens using a full payload,
+but care should be taken in order to not break this compatibility.
+
+### Think About The Future
+
+When creating a change in the update engine, think about 5 years from now:
+
+* How can the change be implemented that five years from now older clients
+ don’t break?
+* How is it going to be maintained five years from now?
+* How can it make it easier for future changes without breaking older clients
+ or incurring heavy maintenance costs?
+
+### Prefer Not To Implement Your Feature In The Updater Client
+If a feature can be implemented from server side, Do NOT implement it in the
+client updater. Because the client updater can be fragile at points and small
+mistakes can have catastrophic consequences. For example, if a bug is introduced
+in the updater client that causes it to crash right before checking for update
+and we can't quite catch this bug early in the release process, then the
+production devices which have already moved to the new buggy system, may no
+longer receive automatic updates anymore. So, always think if the feature is
+being implemented can be done form the server side (with potentially minimal
+changes to the client updater)? Or can the feature be moved to another service
+with minimal interface to the updater client. Answering these questions will pay
+off greatly in the future.
+
+### Be Respectful Of Other Code Bases
+
+The current update engine code base is used in many projects like Android. We
+sync the code base among these two projects frequently. Try to not break Android
+or other systems that share the update engine code. Whenever landing a change,
+always think about whether Android needs that change:
+
+* How will it affect Android?
+* Can the change be moved to an interface and stubs implementations be
+ implemented so as not to affect Android?
+* Can Chrome OS or Android specific code be guarded by macros?
+
+As a basic measure, if adding/removing/renaming code, make sure to change both
+`build.gn` and `Android.bp`. Do not bring Chrome OS specific code (for example
+other libraries that live in `system_api` or `dlcservice`) into the common code
+of update_engine. Try to separate these concerns using best software engineering
+practices.
+
+### Merging from Android (or other code bases)
+
+Chrome OS tracks the Android code as an [upstream branch]. To merge the Android
+code to Chrome OS (or vice versa) just do a `git merge` of that branch into
+Chrome OS, test it using whatever means and upload a merge commit.
+
+```bash
+repo start merge-aosp
+git merge --no-ff --strategy=recursive -X patience cros/upstream
+repo upload --cbr --no-verify .

-# A test script for paycheck.py and the update_payload.py library.
-#
-# This script requires three payload files, along with a metadata signature for
-# each, and a public key for verifying signatures. Payload include:
-#
-# - A full payload for release X (old_full_payload)
-#
-# - A full payload for release Y (new_full_payload), where Y > X
-#
-# - A delta payload from X to Y (delta_payload)
-#
-# The test performs the following:
-#
-# - It verifies each payload against its metadata signature, also asserting the
-# payload type. Another artifact is a human-readable payload report, which
-# is output to stdout to be inspected by the user.
-#
-# - It applies old_full_payload to yield old kernel (old_kern.part) and rootfs
-# (old_root.part) partitions.
-#
-# - It applies delta_payload to old_{kern,root}.part to yield new kernel
-# (new_delta_kern.part) and rootfs (new_delta_root.part) partitions.
-#
-# - It applies new_full_payload to yield reference new kernel
-# (new_full_kern.part) and rootfs (new_full_root.part) partitions.
-#
-# - It compares new_{delta,full}_kern.part and new_{delta,full}_root.part to
-# ensure that they are binary identical.
-#
-# If all steps have completed successfully we know with high certainty that
-# paycheck.py (and hence update_payload.py) correctly parses both full and delta
-# payloads, and applies them to yield the expected result. Finally, each
-# paycheck.py execution is timed.

+// 2). this is a 'current' file. If you make a backwards compatible change to

+// You must not make a backward incompatible change to any AIDL file built
