vm_tools: vmc/concierge: Implement SetCrostiniVmType command When migrating crostini installations to baguette, users will need to have a means of changing the vm type in chrome prefs. This patch creates a concierge command and a vmc frontend to it that allows a user to change vm type for the Linux Development Environment (aka crostini and baguette). The purpose of this command is as a final step in migrating an existing crostini install to a baguette (containerless) one. When the command is issued, the end result should be a change of vm type as represented 1. in the xattr on the underlying disk image 2. in the chrome pref BUG=b:476119187 TEST=deploy to DUT and issue command in vmc NO_IFTTT=IFTTT seems to not be recognizing that i did change both the 'if this' AND 'that' Change-Id: Id98dc6320b35dcd708de2da943bccca069669938 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform2/+/7512463 Commit-Queue: maciek swiech <drmasquatch@google.com> Reviewed-by: Zihan Chen <zihanchen@google.com> Tested-by: maciek swiech <drmasquatch@google.com> NOKEYCHECK=True GitOrigin-RevId: c7fc086328c9fc7add128a180fe65cbd575ee2db
This directory (platform2/system_api) contains constants and definitions like D-Bus service names that are shared between Chromium and Chromium OS.
This directory is only for things like headers and .proto files. No implementation should be added.
When writting a .proto file make sure to use:
option optimize_for = LITE_RUNTIME;
This will force usage of a lite protobuf instead of a full/heavy weight protobuf. The browser only links against the light version, so you will get cryptic link errors about missing parts of Message if you define a protobuf here and then try to use it in Chrome. Currently CrOS links against the full protobuffer library, but that might change in the future.
When declaring a protobuf, avoid use of required unless it is exactly what you mean. “Required is Forever” and very rarely should actually be used. Consult Protocol Buffer Basics: C++ for a detailed of this issue.
