View Source Edeliver.Relup.Instructions.FinishRunningRequests (edeliver v1.9.2)
Notify request processes that a release upgrade starts.
This upgrade instruction waits a short time until current
requests finished and notifies the remaining, that a
code upgrade will appear. If a phoenix
version is used
which supports the upgrade notification feature, the
remaining requests that did not finish but failed during
the upgrade will be replayed with the original request
when the code upgrade is done. This instruction should be
used in conjunction with and after the
Edeliver.Relup.Instructions.SuspendRanchAcceptors
instruction which avoids that new requets are accepted during the upgrade.
To make sure that the http request connections can be found on the node, use this instruction after the
Edeliver.Relup.Instructions.CheckRanchConnections
instruction which will abort the upgrade if the http request connections accepted by ranch cannot be found in the supervision tree.

Functions
Returns name of the application and the timeout in ms to wait until running requests finish.
Waits until the list of processes terminated.
Calls the run/1
function of this module
This module depends on the Edeliver.Relup.Instructions.CheckRanchAcceptors
and
the Edeliver.Relup.Instructions.CheckRanchConnections
module
Appends this instruction to the instructions after the "point of no return"
Callback implementation for Edeliver.Relup.Instruction.modify_relup/2
.
Sends the given event to all processes representing http requests
Waits timeout

@spec arguments( %Edeliver.Relup.Instructions{ changed_modules: term(), down_instructions: term(), down_version: term(), up_instructions: term(), up_version: term() }, Edeliver.Relup.Config.t() ) :: term()
Returns name of the application and the timeout in ms to wait until running requests finish.
These values taken as argument for the run/1
function
@spec bulk_wait_for_termination(processes :: [pid()], timeout :: non_neg_integer()) :: [pid :: pid()]
Waits until the list of processes terminated.
Waits up to timeout
ms and the returns the process ids of the processes which are still running
@spec call_this(arguments :: [term()]) :: Instruction.instruction() | Instruction.instructions()
Calls the run/1
function of this module
from the relup file during hot code upgrade
@spec dependencies() :: [instruction_module :: atom()]
@spec dependencies() :: [Edeliver.Relup.Instructions.CheckRanchAcceptors]
This module depends on the Edeliver.Relup.Instructions.CheckRanchAcceptors
and
the Edeliver.Relup.Instructions.CheckRanchConnections
module
which must be loaded before this instruction for upgrades and unload after this instruction for downgrades.
@spec insert_where() :: Instruction.insert_fun()
Appends this instruction to the instructions after the "point of no return"
but before any instruction which loads or unloads new code, (re-)starts or stops any running processes, or (re-)starts or stops any application or the emulator.
Callback implementation for Edeliver.Relup.Instruction.modify_relup/2
.
Sends the given event to all processes representing http requests
@spec run({otp_application_name :: atom(), timeout :: non_neg_integer()}) :: :ok
Waits timeout
milliseconds until current http requests finished
and notifies remaining request processes that a code upgrad is running and new code will be loaded. This enables phoenix to rerun requests which failed during code loading.
