How to reduce the number of displayed "changes" when running Ansible? -


when running ansible playbook on number of machines regularly, numerous "changes" displayed if nothing changed (anymore).

this can have different reasons. example 1 simple reason registering variables:

tasks: - name: fetch docker_compose_version   shell: docker-compose --version   register: docker_compose_version

this block results in

task [fetch docker_compose_version] ******************************************************************************** changed: [mysrv]

i see change if there has been changed on machine. how can achieve this?

that's changed_when for. example:

- name: fetch docker_compose_version   shell: docker-compose --version   register: docker_compose_version   changed_when: false

for scripts , commands need define condition (there no magic behind, regular modules handle manually too). have @ overriding changed result.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
