创建编译目录失败: %w

Error message

创建编译目录失败: %w

What it means

After creating the build root, compileCliBinary allocates a per-build temp directory with os.MkdirTemp(absBuildRoot, "cli-"). Failure here (wrapped in this error) means a new temp subdir could not be created even though the root exists — typically a race, permission change, or filesystem full condition.

Solutions

1. Check disk space and inodes (df -h / df -i) on the volume holding the build dir and free space
2. Clean up stale cli-* directories left by crashed builds
3. Ensure no external cleanup job deletes the build root while builds run; scope cleanup to old dirs only
4. Grant the server user write permission on the build root again if it changed
5. If a previous build crashed, note MkdirTemp dirs are removed via defer os.RemoveAll only on clean returns — sweep orphans periodically

Example fix

# find and remove orphaned build dirs older than a day
find /var/lib/gva/cli-build -maxdepth 1 -name 'cli-*' -mtime +1 -exec rm -rf {} +

if st, err := os.Stat(cliBuildDir); err != nil || !st.IsDir() {
    return errors.New("build root missing or not a directory")
}

bin, content, err := svc.BuildCliBinary(cli, manifest, goos, goarch)
if err != nil {
    if strings.Contains(err.Error(), "创建编译目录失败") && isTransient(err) {
        time.Sleep(500 * time.Millisecond)
        return svc.BuildCliBinary(cli, manifest, goos, goarch) // one retry
    }
    return err
}

When it happens

Trigger: Disk full or inode exhaustion on the partition holding absBuildRoot; permissions changed on the build root between MkdirAll and MkdirTemp; concurrent cleanup scripts deleting the root mid-build; quota limits on the volume.

Common situations: Long-running servers whose build dir filled up with stale cli-* temp dirs; monitoring jobs or cron cleaning the build root while a build is in flight; small tmpfs volume allocated for the build directory.
