Openbox 3.8.0

A modernized, high-performance continuation of Openbox, re-engineered for strict memory safety, modern toolchains, native XLibre optimization, and a novel polyglot session management pipeline.

---

Overview

The 3.8.0 release bridges the gap between classic minimalist window management and modern systems architecture.

Development upstream has historically relied on legacy code dependencies that trigger extensive diagnostics under modern GCC/Clang toolchains and lack safe, flexible session initialization.

This continuation of Openbox implements a comprehensive modernization pipeline—delivered via an automated patch infrastructure (omni-patch-build.sh)—achieving a 100% zero-warning production build, fixing long-standing memory safety bugs, and introducing a first-of-its-kind Rust/Perl polyglot session manager with three-tier graceful degradation (legacy mode).

Technical Enhancements & Modernization

1. Polyglot Session-Init (New in v3.8.0)

A Rust-supervised, Perl 6-transpiled session manager that replaces legacy autostart exec with a three-tier graceful degradation pipeline:

• Tier 1 — Full Pipeline (Rust + Perl 6): Rust daemonizes and supervises; Perl 6 parses the legacy ~/.config/openbox/autostart config at runtime, strips noise, comments, normalizes ~/ > $HOME/, structures lockfile guards as native Perl 6 conditionals, and emits a clean exec script.
• Tier 2 — Safe Shell Executor (Rust only): When Perl 6 is unavailable, Rust still provides memory-safe daemonization, unified logging, and process supervision while exec the legacy autostart directly via /bin/sh.
• Tier 3 — Pure Legacy (Neither): When neither Rust nor Perl 6 is installed, Openbox falls back to its old native C/shell autostart path unchanged, ensuring zero breakage on minimal or legacy systems.

Unified session logging to ~/.cache/openbox/session-init.log.

2. Strict Memory Safety & Bug Fixes

• obt/prop.c Refactor: Resolved a critical -Wreturn-local-addr compiler violation. Legacy code returned a pointer to a temporary stack-allocated array (single), resulting in runtime undefined behavior and the notorious "Unnamed Window" bug where window title data became corrupted upon function return. This logic has been completely overhauled to utilize persistent heap allocation via g_memdup2, ensuring absolute data persistence and stability.

• obt/xml.c Const-Correctness: Patched libxml2 error handling structures to correctly match modern type checking definitions, shifting definitions to explicitly handle const xmlError pointers seamlessly.

3. GLib 2.70+ API Migration

• Integer Overflow Mitigation: Migrated all legacy, security-vulnerable g_memdup routines globally to the modern g_memdup2 API specification, preventing potential integer wrapped allocation exploits.

• Modern Pattern Matching: Refactored deprecated utility logic to leverage g_pattern_spec_match_string and g_pattern_spec_match.

• Diagnostic Hygiene: Suppressed persistent toolchain noise regarding legacy GTimeVal and Pango API deprecations via targeted localized #pragma overrides within foundational header structures (frame.h, render.h, obt.h).

4. Native Environment Optimization

• Display Server Target: Architecture and compilation parameters are explicitly optimized out-of-the-box for the modern XLibre display server environment, yielding dramatic rendering efficiency gains and a completely fluid, stutter-free compositor phase compared to stock legacy Xorg environments.

• Clean System Prefixing: Targets /usr/local defaults for cleanly separating modernized system libraries (libobt.so.2, libobrender.so.32) from legacy or vendor packages.

Dependencies

Required

• C Toolchain: GCC or Clang with C11 support
• GLib 2.70+: Core runtime library (g_memdup2, pattern matching APIs)
• libxml2: XML configuration parsing
• X11 (Xorg) / XLibre: X Display server libraries and headers
• Pango: Text rendering and font handling
• GNU Autotools: autoconf, automake, libtool (for building from source)

Optional, but highly recommended (Polyglot Session-Init)

• Rust Toolchain: Required to compile session-init from source. If absent, the build system uses the pre-compiled fallback binary included in the repository.
• Raku (Perl 6): Required for Tier 1 full transpilation pipeline. If absent, session-init automatically falls back to Tier 2 (safe shell exec) or Tier 3 (pure legacy mode) at runtime. No build-time failure occurs.

Note: The omni-patch-build.sh script performs automatic detection of both Rust and Perl 6 at build time and configures the appropriate execution tier. All three tiers function correctly regardless of which optional dependencies are installed.

Architecture & Build Strategy

The project employs a structured VPATH build execution matrix to separate binary generation from the immutable source tree.
