创建临时文件失败: %w

Error message

创建临时文件失败: %w

What it means

os.CreateTemp failed to create the temporary file used to stage the downloaded skill zip. This is a local filesystem error: os.CreateTemp fails when the temp directory (TMPDIR or /tmp) is unwritable, doesn't exist, or the system is out of inodes/space.

Solutions

1. Check TMPDIR and /tmp: ls -ld /tmp; touch /tmp/probe as the server user
2. Free disk space / clean the filesystem if 'no space left on device'
3. Mount a writable emptyDir/tmp volume in containerized deployments
4. Verify the wrapped error: permission denied vs no space vs no such file or directory

Example fix

// pin a known-writable temp dir in containerized deployments
// before (relies on TMPDIR)
tmpFile, err := os.CreateTemp("", "gva-skill-*.zip")
// after
tmpFile, err := os.CreateTemp("/var/tmp/gva", "gva-skill-*.zip") // dir pre-created with correct perms

probe := filepath.Join(os.TempDir(), ".gva-probe")
if f, err := os.Create(probe); err != nil {
    // temp dir unwritable/full — fix before attempting downloads
} else { f.Close(); os.Remove(probe) }

if err := DownloadOnlineSkill(ctx, req); err != nil && strings.Contains(err.Error(), "创建临时文件失败") {
    // check TMPDIR writability and disk space; surface a storage alert
}

When it happens

Trigger: Calling DownloadOnlineSkill on a server whose TMPDIR points to a nonexistent/unwritable directory, /tmp is mounted read-only or full (no space left on device), or the process user lacks write permission to the temp dir.

Common situations: Containers with read-only root filesystems and no writable tmp mount; disk full after large log accumulation; hardened tmp permissions (sticky bit/ownership); TMPDIR misconfiguration in systemd units or k8s pods.
