From aed547f4abf8ec6f78ea7389dc5098fe0f40b0b1 Mon Sep 17 00:00:00 2001 From: Adib Rastegarnia Date: Fri, 11 Sep 2020 15:03:25 -0700 Subject: [PATCH] Employ mastership info for session management (#1189) * Implement session management using mastership information * Use exponential backoff retry package * Initialize topo channel from manager for now * checking term for updating the device state * Fix get current term * return the test to normal condition * Fix a small bug * Handle device updates * Use one single channel and single go routine for updating the device state * revert the change * Fix retries to make sure we stop it if there is mastership change * For debugging * Create a channel per session for handling device response events * comment out the session manager test * Fix consistency bug and make sure we check mastership term on the same device object * Remove old files and add some unit tests * update device state unit test * clean up the code * Move handling of mastership events to session manager * Set replicaCount to 1 * fix unit test * Use one mastership state instead of reading from store * Fix unit test --- go.mod | 3 + pkg/manager/devicehandler.go | 95
