feat: cuttlefish driver - #936
Conversation
📝 WalkthroughWalkthroughThe pull request adds a Cuttlefish Host Orchestrator driver, composite client, Click commands, asynchronous operation handling, child power and flasher drivers, tests, documentation, and package registration. ChangesCuttlefish driver integration
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟠 High · up to The new driver can fail during normal device start and stop flows because it calls unavailable ADB methods, while some Host Orchestrator responses may trigger duplicate device creation or reject valid device data. These are concrete correctness and availability issues that should be fixed before merging. Sequence Diagram(s)sequenceDiagram

We should think about how to handle ADB, maybe a nested ADB driver within a Cuttlefish composite driver or maybe we just make an example of how to handle this since ADB is probably the most important aspect here.

in my testing I was using it as a sibling, but a child driver might actually be nicer here, since we have a bit of dance of:
j cuttlefish create ...
j adb connect <using output from first command> (added to the adb driver in another PR)
i'll check if it's simple to not have to do that

The ADB driver already does wrapping of the underlying ADB connection handling, so it might be easy to grab that and then automatically route it via j cuttlefish adb or something like that.

We might want to expose more complex configuration here like the image to download or host configuration, so the user can just do cuttlefish.on() and get a pre-configured device, but that might also be fine to put into the ExporterClass config. Thoughts @mangelajo?

EnvConfig is considered unstable (or they just forgot to remove the comment)
https://github.com/google/android-cuttlefish/blob/762bf3a532d7c7634cfe317d8c71b7cdcb4fdbae/frontend/src/host_orchestrator/api/v1/messages.go#L25
So we need to think about supported version, but perhaps simply adding an env_config field and forwarding would be enough

Adding flasher support might also be a nice thing to do later where we can "flash" an image to a local path and then boot from that.

_ADB_PATCHESholds module-level patcher objects. Four places start and stop the same objects: thedrvfixture and the tests at lines 240-248, 251-259, and 266-274. Two problems follow.First, the start/stop boilerplate is duplicated four times.

Google Android Cuttlefish cvd fetch --default_build build source format @ab/ aosp-android-latest-release
💡 Result:
The command cvd fetch is used to download Cuttlefish virtual device images and host tools from the Android Continuous Integration (CI) build server [1]. Regarding your specific query format: The --default_build flag accepts values in specific formats to identify which build to download [2]. The syntax for these build source flags is generally [2]: "branch/build_target" - The latest build of "branch" for "build_target" [2]. "build_id/build_target" - A specific "build_id" for "build_target" [2]. "branch" - The latest build of "branch" for the default target (aosp_cf_x86_64_phone-userdebug) [2]. "build_id" - A specific "build_id" for the default target (aosp_cf_x86_64_phone-userdebug) [2]. The example value "aosp-android-latest-release" represents a branch name, which is commonly used to fetch the latest available build for that branch [1]. While the command syntax does not typically use "@ab/" as a prefix directly in the flag argument, you would typically execute the command by specifying the branch or build ID to the --default_build flag [2]. For example: cvd fetch --default_build=aosp-android-latest-release The cvd fetch tool automatically handles the retrieval of the necessary images (such as vendor.img) and the host package (cvd-host_package.tar.gz) from the Android build system [1][2]. Always ensure you download the host package from the same build as your images to maintain compatibility [1].

Use the cvd fetch-supported build-source syntax.
The command-line example uses cvd fetch --default_build=aosp-android-latest-release/aosp_cf_x86_64_auto-userdebug, but the env_config build-source section documents Android CI builds as @ab/<branch>/<target>. Use the no-prefix branch/target form in the Android CI example unless the README adds support for @ab/ for disk.default_build.

Treat an unexpected /cvds body as a discovery failure.
Lines 151-152 return [] when the body is not a JSON object. CvdPower.on then reads that as "no CVD exists" and sends POST /cvds. A 200 response with a non-JSON body, for example an HTML page from an intermediate proxy, can therefore create a second CVD on a host that already runs one. This contradicts the docstring on lines 147-148.
If you apply this fix, update test_get_existing_cvds_non_dict in driver_test.py (lines 277-279) to expect the error.
🐛 Proposed fix
result = self._request("GET", "/cvds")
if not isinstance(result, dict):
- return []
+ raise CuttlefishError(f"unexpected response from GET /cvds: {result!r}")
all_cvds = result.get("cvds", [])📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Replace the invalid ADB helper calls. AdbServer and TcpNetwork do not define connect_device() or disconnect_device(). These calls raise AttributeError at runtime when an actual ADB child is used.

Add jumpstarter-driver-cuttlefish, managing Android Cuttlefish virtual devices (CVDs) through the Host Orchestrator REST API.
Composite driver with three children:
starts an existing one, off() stops it, off(destroy=True)
deletes it.
Also exposes cuttlefish-specific operations: powerwash, powerbtn, and CVD listing.
