From 3d2172d93a638972e4046c79341873caf2393436 Mon Sep 17 00:00:00 2001 From: Levi Neely Date: Wed, 29 Jul 2026 20:00:47 +0200 Subject: [PATCH] session: eliminate Core interface, use concrete *agent.Session - Delete session/core.go (the consumer-defined interface) - Change Session.Core field from interface to *agent.Session - Change NewSession and ManagerConfig.NewCore to use concrete type - Rewrite all tests to use real sessions with backend.Noop The 9p layer now depends directly on the concrete type from ollie/session. No more interface indirection. Tests exercise real session behavior instead of stub methods. --- main_test.go | 969 +++++++++++++++++++++------------------------ session/core.go | 55 --- session/session.go | 10 +- 3 files changed, 465 insertions(+), 569 deletions(-) delete mode 100644 session/core.go diff --git a/main_test.go b/main_test.go index 7babe14..40496bd 100644 --- a/main_test.go +++ b/main_test.go @@ -7,10 +7,10 @@ import ( "os" "path/filepath" "strings" + "sync" "testing" "time" -
