A misunderstanding of the ioctl() call interface. If mutable=False then fcntl.ioctl() actually returns the arg buffer back. This accidentally worked on Python2 because int and str comparison did not return an error. Error reporting is actually done by raising IOError on Python2 and OSError on Python3. * Properly handle errors in set_timeout(), have them result in only a warning if watchdog support is not required. * Improve watchdog device driver name display on Python3 * Eliminate race condition in watchdog feature tests. The pinged/closed states were not getting reset properly if the checks ran too quickly. Add explicit reset points in feature test so the check is unambiguous.

Feature: watchdog
|
|
Verify that watchdog gets pinged and triggered under appropriate circumstances.
|
|
|
|
Scenario: watchdog is opened and pinged
|
|
Given I start postgres0 with watchdog
|
|
Then postgres0 is a leader after 10 seconds
|
|
And postgres0 role is the primary after 10 seconds
|
|
And postgres0 watchdog has been pinged after 10 seconds
|
|
|
|
Scenario: watchdog is disabled during pause
|
|
Given I run patronictl.py pause batman
|
|
Then I receive a response returncode 0
|
|
When I sleep for 2 seconds
|
|
Then postgres0 watchdog has been closed
|
|
|
|
Scenario: watchdog is opened and pinged after resume
|
|
Given I reset postgres0 watchdog state
|
|
And I run patronictl.py resume batman
|
|
Then I receive a response returncode 0
|
|
And postgres0 watchdog has been pinged after 10 seconds
|
|
|
|
Scenario: watchdog is disabled when shutting down
|
|
Given I shut down postgres0
|
|
Then postgres0 watchdog has been closed
|
|
|
|
Scenario: watchdog is triggered if patroni stops responding
|
|
Given I reset postgres0 watchdog state
|
|
And I start postgres0 with watchdog
|
|
Then postgres0 role is the primary after 10 seconds
|
|
When postgres0 hangs for 30 seconds
|
|
Then postgres0 watchdog is triggered after 30 seconds
