迁移旧站点配置失败

Error message

迁移旧站点配置失败: %w

What it means

Thrown at plugin/gying.go:701 during config load/upgrade. When the stored baseURL matches a legacy URL form (isLegacyGyingBaseURL), the plugin rewrites it to DefaultGyingBaseURL and calls p.saveConfig; if persisting the migrated value fails, the write error is wrapped with this message.

Solutions

1. Inspect the wrapped %w cause to see the actual save failure (permission, path, disk).
2. Ensure the plugin's config/cache directory exists and is writable by the process user (chmod/chown as needed).
3. Manually update the stored baseURL to the current default so migration is skipped on next start.
4. Check for another process holding the config file and retry after freeing it.

Example fix

// before (read-only dir)
chmod 555 ./cache
// after
chmod 755 ./cache && chown $USER ./cache

// check config dir writability before load
info, err := os.Stat(configDir)
if err != nil || !info.IsDir() { return fmt.Errorf("config dir missing: %s", configDir) }
if err := os.WriteFile(filepath.Join(configDir, ".wtest"), nil, 0644); err != nil { return fmt.Errorf("config dir not writable") }
os.Remove(filepath.Join(configDir, ".wtest"))

if err := p.loadConfig(); err != nil {
	if strings.Contains(err.Error(), "迁移旧站点配置失败") {
		log.Printf("config migration failed, fix permissions on config dir: %v", err)
	}
	return err
}

When it happens

Trigger: Plugin startup or config load where an old-format baseURL is detected AND saving the new default fails — typically because the config file is read-only, the directory is missing, or disk is full.

Common situations: Upgrading the plugin while running under a read-only filesystem or a user without write permission to the config/cache directory; config file corrupted or locked by another process.

Understand the failure class

Background: "failed to write file", "Could not save figure", "Error saving remote file" — file write failed: causes and fixes across languages and libraries — this error's family across 38 libraries.
