via the API. TaskState is the current task state.

# Query for all tasks currently TaskState.RUNNING. This includes tasks
# currently in the overhead phase; mapping input files or archiving outputs
# back to the server.
# Query for all tasks currently TaskState.PENDING or TaskState.RUNNING. This
# is the query for the 'active' tasks.
# Query for all tasks that completed normally as TaskState.COMPLETED,
# independent of the process exit code.
# Query for all tasks that completed normally as TaskState.COMPLETED and that
# had exit code 0.
# Query for all tasks that completed normally as TaskState.COMPLETED and that
# had exit code not 0.
# Query for all tasks that are TaskState.EXPIRED.

# Query for all tasks that are TaskState.BOT_DIED.
# Query for all tasks that are TaskState.CANCELED.

# Query for all tasks that are TaskState.CLIENT_ERROR.
class TaskState(messages.Enum):
"""Represents the current task state.
Some states are still mutable: PENDING and RUNNING. The others are final and
will not change afterward.
A task is guaranteed to be in exactly one state at any point of time.
Do not confuse TaskStateQuery and TaskState. TaskStateQuery is to query tasks
via the API. TaskState is the current task state.
As you read the following constants, astute readers may wonder why these
constants look like a bitmask. This is because of historical reasons and this
is effectively an enum, not a bitmask.

# overhead to fetch input files, the actual task running, and the tear down
# overhead to archive output files to the server.
RUNNING = 0x10
# The task is currently pending. This means that no bot reaped the task. It
# will stay in this state until either a task reaps it or the expiration
# elapsed. The task pending expiration is specified as
# TaskSlice.expiration_secs, one per task slice.
PENDING = 0x20
# The task is not pending anymore, and never ran due to lack of capacity. This
# means that other higher priority tasks ran instead and that not enough bots
# were available to run this task for TaskSlice.expiration_secs seconds.
EXPIRED = 0x30
# The task ran for longer than the allowed time in
# TaskProperties.execution_timeout_secs or TaskProperties.io_timeout_secs.
# This means the bot forcefully killed the task process as described in the
# graceful termination dance in the documentation.
TIMED_OUT = 0x40
# The task ran but the bot had an internal failure, unrelated to the task
# itself. It can be due to the server being unavailable to get task update,
# the host on which the bot is running crashing or rebooting, etc.
BOT_DIED = 0x50
# The task never ran, and was manually cancelled via the 'cancel' API before
# it was reaped.
# The task ran and completed normally. The task process exit code may be 0 or
# another value.
# The task ran but was manually killed via the 'cancel' API. This means the
# bot forcefully killed the task process as described in the graceful
# termination dance in the documentation.
KILLED = 0x80
# The task was never set to PENDING and was immediately refused, as the server
# determined that there is no bot capacity to run this task. This happens
# because no bot exposes a superset of the requested task dimensions.
# Set TaskSlice.wait_for_capacity to True to force the server to keep the task
# slice pending even in this case. Generally speaking, the task will
# eventually switch to EXPIRED, as there's no bot to run it. That said, there
# are situations where it is known that in some not-too-distant future a wild
# bot will appear that will be able to run this task.
# The task run into an issue that was caused by the client. It can be due to
# a bad CIPD or CAS package. Retrying the task with the same parameters will
