CrashCatch v1.2.0

🚀 CrashCatch v1.2.0

CrashCatch v1.2.0 is our biggest update yet — bringing full Linux support, powerful callback hooks, and the groundwork for cross-platform crash diagnostics — all within a single header file.

---

✨ What's New

🔧 Linux Support Finalized

• ✅ POSIX signal handling now supports:
  • SIGSEGV – Segmentation fault
  • SIGABRT – Aborted process
  • SIGFPE – Floating-point exception
  • SIGILL, SIGBUS – Illegal instruction, bus errors
• ✅ Stack traces via backtrace()
• ✅ Demangled function names using __cxa_demangle
• ✅ Executable path detection via /proc/self/exe

🧠 New CrashContext Struct

• Contains detailed crash metadata passed into callback hooks:
  • .dmp file path (Windows)
  • .txt log path
  • timestamp
  • signal or exception code

🪝 onCrash and onCrashUpload Hooks

• New configurable callbacks:

  config.onCrash = [](const CrashContext& ctx) {
      // Cleanup or logging before app terminates
  };
  
  config.onCrashUpload = [](const CrashContext& ctx) {
      // Send crash file to your server/service
  };```
  

Enabled cleanup, telemetry, logging, or remote upload logic right from the app!

🛑 Skips Debug Exceptions

Windows debug control exceptions (DBG_PRINTEXCEPTION_C, DBG_CONTROL_C) are now ignored to avoid false positives.

🧪 Examples Added

• 🧵 Example_ThreadCrash.cpp
• ➗ Example_divideByZero.cpp
• 💼 Example_FullConfig.cpp — now includes onCrash
• ☁️ Example_UploadCrash.cpp — demonstrates using onCrashUpload to simulate a remote crash report

---

🛠 Internal Improvements

• Reorganized internal logic with clear inline documentation
• Hardened Linux support for production use
• Improved stack trace readability
• Unified timestamp generation and path formatting

---

📝 Documentation

• Updated README.md with full platform details
• New linux.md page under GitHub Pages
• Refined screenshots, quick start, and crash log examples

---

📦 CMake & CI

• Enhanced CMake integration remains header-only
• GitHub Actions CI runs automatically on push

---

---

🧭 Roadmap (Next Up)

• macOS support via Mach exceptions
• Remote crash uploads (via webhook or HTTPS endpoint)
• .json crash logs
• Crash viewer UI tool
• Auto-rotate / cleanup of old log

CrashCatch v1.1.0 – Now with Linux Support

[1.1.0] – 2025-04-04

Added

• 🐧 Linux support with POSIX signal handling
• Signal-based crash capture for SIGSEGV, SIGABRT, and SIGFPE
• Executable path resolution for Linux using /proc/self/exe
• Stack traces using backtrace() and backtrace_symbols()

Changed

• Refactored header-only implementation to be cross-platform
• Improved crash log structure and formatting on Linux
• Now detects and logs platform, architecture, and executable location

---

✅ Bug Fix: Linux Compatibility Crash (#1)

Resolved a Linux-specific compilation error reported in #1, which occurred due to the use of Windows.h-specific types and headers on non-Windows systems.

🔧 What changed:

• CrashCatch now conditionally includes only platform-appropriate headers (e.g., Windows.h for Windows, signal.h and execinfo.h for Linux).
• Windows-specific functionality (e.g., MiniDumpWriteDump, MessageBoxA) is fully gated behind #ifdef blocks.
• Linux support now builds cleanly on GCC/Clang without needing to modify the source.

💡 Impact:

CrashCatch v1.1.0 is now cross-platform out of the box and builds cleanly on Linux with no manual patching required.

---

Fixed

• Crash log generation on Linux wasn't triggered for certain signals
• Windows-only includes and defines now guarded by platform macros

Zip File

The zip file has the CMakeLists.txt and CrashCatch.hpp files included

CrashCatch v1.0.0 - Initial Public Release

🚀 CrashCatch v1.0.0 – Initial Public Release

CrashCatch is a single-header crash reporting library for modern C++ applications. This first release supports Windows and generates .dmp and .txt logs for unhandled exceptions.

• 💾 Minidump file (.dmp) generation
• 📋 Human-readable log (.txt) with:
  • Stack trace
  • App version / build info
  • Thread ID / exception code
  • Uptime
• ✅ Zero-config mode (CRASHCATCH_AUTO_INIT)
• ⚙️ Configurable versioning, notes, dialog, and crash callback
• 🪛 One-liner setup via CrashCatch::enable()
• 🪄 Optional message box on crash (GUI-friendly)

📦 Installation

🟢 CrashCatch is a single-header library.

To use it, simply copy 'CrashCatch.hpp' file into your project:

#include "CrashCatch.hpp"

Or you can auto-init with:

#define CRASHCATCH_AUTO_INIT
#include "CrashCatch.hpp"
