devlake-go mysql connection failure

Closed this issue · 1 comments

Description

devlake-go fails to connect to devlake database. The problem appears to be related to the value of the default_authentication_plugin MySQL server parameter.

The MySQL server hosting our devlake database runs with the default_authentication_plugin set to mysql_native_password. In this case, devlake-go fails to connect no matter whether the devlake user' password is created with the native or caching_sha2_password plugin.

The connection can be established, however, when I recompile the client with the mysql config parameter AllowNativePasswords set to true.

Expected behavior

❯ DEVLAKE_DBUSER=devlake DEVLAKE_DBPASS=....  make run-api
--> Compiling the project
go build -ldflags "-X main.gitsha=ec5c1ab -X main.compiled=1709134032" -o bin/opendora-api api/main.go
--> Running the OpenDORA API
2024/02/28 16:27:15 connected to DevLake database

Actual Behavior

❯ DEVLAKE_DBUSER=devlake DEVLAKE_DBPASS=... make run-api
--> Compiling the project
go build -ldflags "-X main.gitsha=ec5c1ab -X main.compiled=1709134118" -o bin/opendora-api api/main.go
--> Running the OpenDORA API

exit status 1

Reproduction steps

  • set up devlake with MySQL 8.* and the server parameter default_authentication_plugin set to mysql_native_password
  • follow devlake-go README, execute make run-api with your devlake database details
  • devlake-go fails to connect to the database

The following modification to devlake-go/api/sql_client/client.go fixes the connection issue for this particular case:

diff --git a/devlake-go/api/sql_client/client.go b/devlake-go/api/sql_client/client.go
index a56eca4..ea359ad 100644
