From 1ad42dbbee43afbcafbe1fe3522948cae92cb816 Mon Sep 17 00:00:00 2001 From: Kyle Isom Date: Wed, 25 Mar 2026 16:57:02 -0700 Subject: [PATCH] Migrate db and config to mcdsl - db.Open: delegate to mcdsl/db.Open (WAL, FK, busy timeout, 0600) - db.Migrate: convert function-based migrations to mcdsl/db.Migration SQL strings, delegate to mcdsl/db.Migrate - db.Snapshot: delegate to mcdsl/db.Snapshot (adds 0600 permissions) - config: replace local Duration with mcdsl/config.Duration alias, replace Load with mcdsl/config.Load[T] + Validator interface - Remove direct modernc.org/sqlite and go-toml/v2 dependencies (now indirect via mcdsl) - Update TestEnvOverrideInvalidDuration: mcdsl silently ignores invalid env duration values (behavioral change from migration) - All existing tests pass Co-Authored-By: Claude Opus 4.6 (1M context) --- go.mod | 13 +-- go.sum | 12 +-- internal/config/config.go | 124 ++++++++------------------- internal/config/config_test.go | 12 ++- internal/db/db.go | 38 +++------ internal/db/migrations.go | 151 ++++++++++----------------------- internal/db/snapshot.go | 11 ++- 7 files changed, 116 insertions(+), 245 deletions(-) diff --git a/go.mod b/go.mod index a6b55ce..397ad34 100644 --- a/go.mod +++ b/go.mod @@ -1,29 +1,32 @@ module git.wntrmute.dev/kyle/mc-proxy -go 1.25.0 +go 1.25.7 require ( + git.wntrmute.dev/kyle/mcdsl v0.0.0 github.com/oschwald/maxminddb-golang v1.13.1 -
