From 3860fa278dc2b901705ffbddbed5cf59d70a85e4 Mon Sep 17 00:00:00 2001 From: EcoosUP Date: Thu, 10 Sep 2026 12:06:13 -0300 Subject: [PATCH] fix(concurrency): guard the three shared maps with a mutex MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit clientPointer, myClientPointer and killChannel are created once at startup and passed by reference into eleven packages. All of them read and wrote those plain Go maps from different goroutines, with no synchronisation. Go does not tolerate that: the runtime kills the process with fatal error: concurrent map writes and a fatal error is not recoverable — a deferred recover() does not catch it. Measured in production: the process died inside StartClient while five instances were connecting at once. The orchestrator restarted it within seconds, but every number was offline in the meantime, and it repeats on any restart that brings up more than a couple of instances together. The three maps become safemap.Map[T], a generic wrapper over a RWMutex. It lives in its own package because MyClient is defined in pkg/whatsmeow/service, and putting the type there would create an import cycle with the ten packages that receive the maps. 98 call sites changed across 12 files, with the compiler as the judge: anything missed is a build error, not a silent bug. Tests: with -race, a plain map running the same exercise reports DATA RACE and fails, while safemap.Map passes. Both halves verified. --- cmd/evolution-go/main.go | 5 +- pkg/call/service/call_service.go | 9 +- pkg/chat/service/chat_service.go | 9 +- pkg/community/service/community_service.go | 9 +- pkg/group/service/group_service.go | 9 +- pkg/instance/service/instance_service.go | 85 ++++++++--------- pkg/label/service/label_service.go | 9 +- pkg/message/service/message_service.go | 9 +- pkg/newsletter/service/newsletter_service.go | 9 +- pkg/safemap/safemap.go | 99 ++++++++++++++++++++ pkg/safemap/safemap_test.go | 71 ++++++++++++++ pkg/sendMessage/service/send_service.go | 31 +++--- pkg/user/service/user_service.go | 9 +- pkg/whatsmeow/service/whatsmeow.go | 77 +++++++-------- 14 files changed, 311 insertions(+), 129 deletions(-) create mode 100644 pkg/safemap/safemap.go create mode 100644 pkg/safemap/safemap_test.go diff --git a/cmd/evolution-go/main.go b/cmd/evolution-go/main.go index 5234583f9..7ca5055df 100644 --- a/cmd/evolution-go/main.go +++ b/cmd/evolution-go/main.go @@ -1,6 +1,7 @@ package main import ( + "github.com/evolution-foundation/evolution-go/pkg/safemap" "context" "database/sql" "flag" @@ -83,8 +84,8 @@ func init() { } func setupRouter(db *gorm.DB, authDB *sql.DB, sqliteDB *sql.DB, config *config.Config, conn *amqp.Connection, exPath string, runtimeCtx *core.RuntimeContext) *gin.Engine { -
