This mechanism was however never used and resulted in an misinterpretation in the force-kill PR #6793 introducing a bug fixed in PR #6870. The mechanism of `wait` and `timeout` was also never correctly implemented. In this PR we rectify the logic and simplify it by handling immediate and scheduled actions the same way. Related commits in aiida-core 83880185bd, cd0d15c79d and plumpy 1b6ecb8f One can specifiy a `timeout <= 0` to express that the action should not wait for a response while one can specify `timeout==float('inf')` (default value) to wait until a response has been received without a timeout. --- src/aiida/cmdline/commands/cmd_process.py | 36 ++++++------ src/aiida/cmdline/params/options/main.py | 7 --- src/aiida/engine/processes/control.py | 69 +++++++---------------- tests/cmdline/commands/test_process.py | 42 +++++++------- tests/engine/processes/test_control.py | 16 +++--- 5 files changed, 65 insertions(+), 105 deletions(-) diff --git a/src/aiida/cmdline/commands/cmd_process.py b/src/aiida/cmdline/commands/cmd_process.py index a8dd349f2a..7fa4483ea7 100644 --- a/src/aiida/cmdline/commands/cmd_process.py +++ b/src/aiida/cmdline/commands/cmd_process.py @@ -25,6 +25,16 @@ verdi daemon start """ +ACTION_TIMEOUT = OverridableOption( + '-t', + '--timeout', + type=click.FLOAT, + default=float('inf'), + show_default=True, + help='Time in seconds to wait for a response before timing out.
