From 569854d6348e1cd74e8d654c88720e5517898f1a Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Tue, 4 Aug 2020 15:51:13 -0400 Subject: Unconditionally retrieve pod names via API The ListContainers API previously had a Pod parameter, which determined if pod name was returned (but, notably, not Pod ID, which was returned unconditionally). This was fairly confusing, so we decided to deprecate/remove the parameter and return it unconditionally. To do this without serious performance implications, we need to avoid expensive JSON decodes of pod configuration in the DB. The way our Bolt tables are structured, retrieving name given ID is actually quite cheap, but we did not expose this via the Libpod API. Add a new GetName API to do this.
