From 22915102d4f9db6ac90b15c308fd8b6c91c83cac Mon Sep 17 00:00:00 2001 From: Alexander Renz Date: Wed, 7 Jan 2026 20:41:53 +0100 Subject: [PATCH] CRITICAL FIX: Eliminate all hardcoded /tmp paths - respect WorkDir configuration This is a critical bugfix release addressing multiple hardcoded temporary directory paths that prevented proper use of the WorkDir configuration option. PROBLEM: Users configuring WorkDir (e.g., /u01/dba/tmp) for systems with small root filesystems still experienced failures because critical operations hardcoded /tmp instead of respecting the configured WorkDir. This made the WorkDir option essentially non-functional. FIXED LOCATIONS: 1. internal/restore/engine.go:632 - CRITICAL: Used BackupDir instead of WorkDir for extraction 2. cmd/restore.go:354,834 - CLI restore/diagnose commands ignored WorkDir 3. cmd/migrate.go:208,347 - Migration commands hardcoded /tmp 4. internal/migrate/engine.go:120 - Migration engine ignored WorkDir 5. internal/config/config.go:224 - SwapFilePath hardcoded /tmp 6. internal/config/config.go:519 - Backup directory fallback hardcoded /tmp 7. internal/tui/restore_exec.go:161 - Debug logs hardcoded /tmp 8. internal/tui/settings.go:805 - Directory browser default hardcoded /tmp 9. internal/tui/restore_preview.go:474 - Display message hardcoded /tmp NEW FEATURES: - Added Config.GetEffectiveWorkDir() helper method - WorkDir now respects WORK_DIR environment variable - All temp operations now consistently use configured WorkDir with /tmp fallback IMPACT: - Restores on systems with small root disks now work properly with WorkDir configured - Admins can control disk space usage for all temporary operations - Debug logs, extraction dirs, swap files all respect WorkDir setting Version: 3.42.1 (Critical Fix Release) --- bin/README.md | 4 ++-- cmd/migrate.go | 20 ++++++++++++-------- cmd/restore.go | 14 ++++++++------ internal/config/config.go | 22 ++++++++++++++++++++-- internal/engine/snapshot_engine.go | 2 ++ internal/migrate/engine.go | 2 +- internal/restore/cloud_download.go | 3 ++- internal/restore/engine.go | 7 ++++--- internal/tui/restore_exec.go | 6 ++++-- internal/tui/restore_preview.go | 2 +- internal/tui/settings.go | 2 +- 11 files changed, 57 insertions(+), 27 deletions(-) diff --git a/bin/README.md b/bin/README.md index 2eceece..6f516d9 100644 --- a/bin/README.md +++ b/bin/README.md @@ -4,8 +4,8 @@ This directory contains pre-compiled binaries for the DB Backup Tool across mult ## Build Information -
