From 59617279c6ec53f15e13f52cc5d2dbbc5a4b570e Mon Sep 17 00:00:00 2001 From: Philipp Winter Date: Sun, 1 Dec 2024 11:29:00 -0600 Subject: [PATCH] Re-work the way we deal with Docker logs. In particular: * Don't overwrite a function's returned error when closing a reader because this can result in an error being overridden with `nil`. * Turns out that Docker already provides `DisplayJSONMessagesStream`, which does what we've been attempting to do. Use that instead. --- cmd/veil-verify/docker.go | 130 ++- cmd/veil-verify/main.go | 12 +- go.mod | 2 +- go.sum | 2 + vendor/github.com/Azure/go-ansiterm/LICENSE | 21 +
