 4. **Troubleshooting:**
   * **FUSE:** If the AppImage fails to launch on newer distributions, ensure `libfuse2` (or `fuse2` on Arch/Fedora) is installed.
   * **Desktop Entry:** After installing via `.rpm`, `.deb`, or `.pkg.tar.zst`, the launcher should automatically appear in your App Library/Grid.
+   * Missing libxcrypt.so.1: Install `libxcrypt-compat` using your package manager

+# Steam Deck / Ubuntu LTS Crash Investigation
+
+## Status: UNSOLVED
+
+**Last updated:** 2026-01-27
+
+No stable solution found. jemalloc helps occasionally but crashes still occur randomly.
+
+---
+
+## Problem Summary
+
+The Hytale F2P launcher's client patcher causes crashes on Steam Deck and Ubuntu LTS with the error:
+```
+free(): invalid pointer
+```
+or
+```
+SIGSEGV (Segmentation fault)
+```
+
+The crash occurs after successful authentication, specifically right after "Finished handling RequiredAssets".
+
+**Affected Systems:**
+- Steam Deck (glibc 2.41)
+- Ubuntu LTS
+
+**Working Systems:**
+- macOS
+- Windows
+- Older Arch Linux (glibc < 2.41)
+
+**Critical Finding:** The UNPATCHED original binary works fine on Steam Deck. The crash is caused by ANY binary patching.
+
+---
+
+## What Was Tried (All Failed)
+
+### Memory Allocators
+| Approach | Result |
+|----------|--------|
+| `LD_PRELOAD=/usr/lib/libjemalloc.so.2` | Works randomly (3/10 times), not stable |
+| `MALLOC_CHECK_=0` | No effect |
+| `MALLOC_PERTURB_=255` | No effect |
+| `GLIBC_TUNABLES=glibc.malloc.tcache_count=0` | No effect |
+
+### Process/Scheduling
+| Approach | Result |
+|----------|--------|
+| `taskset -c 0` (single core) | Game too slow, stuck at connecting |
+| `taskset -c 0,1` or `0-3` | Still crashes |
+| `nice -n 19` | No effect |
+| `chrt --idle 0` | No effect |
+| `strace -f` | No effect |
+
+### Linker/Loading
+| Approach | Result |
+|----------|--------|
+| `LD_BIND_NOW=1` | No effect |
+| Wrapper script with LD_PRELOAD | No effect |
+| Shell spawn with inline LD_PRELOAD | No effect |
+
+### Patching Variations
+| Approach | Result |
+|----------|--------|
+| Null-padding after replacement | Crashes (made it worse) |
+| No null-padding (develop behavior) | Still crashes |
+| Minimal patches (3 instead of 6) | Still crashes |
+| Ultra-minimal (1 patch - domain only) | Still crashes |
+| Skip sentry patch | Still crashes |
+| Skip subdomain patches | Still crashes |
+
+**Key Finding:** Even patching just 1 string (main domain only) causes the crash.
+
+---
+
+## String Occurrences Found
+
+### Length-Prefixed Format
+Found by default patcher mode:
+
+| Offset | Content | Notes |
+|--------|---------|-------|
+| 0x1bc5d63 | `hytale.com` | **Surrounded by x86 code!** |
+
+### UTF-16LE Format (3 occurrences)
+| Offset | Content |
+|--------|---------|
+| 0x1bc5ad7 | `sentry.hytale.com/...` |
+| 0x1bc5b3f | `https://hytale.com/help...` |
+| 0x1bc5bc9 | `store.hytale.com/?...` |
+
+---
+
+## Binary Analysis
+
+When patching with length-prefixed mode:
+
+```
+< 01bc5d60: 5933 b80a 0000 0068 0079 0074 0061 006c  Y3.....h.y.t.a.l

+> 01bc5d70: 006f 006c 002e 0077 0073 8933 8807 0000  .o.l...w.s.3....
+```
+
+**Structure:**
+```
+5933 b8 | 0a000000 | h.y.t.a.l.e...c.o.m | 8933 8807 0000
+???????? | len=10   | string content      | mov [rbx],esi?
+```
+
+- `5933 b8` before string - could be code or metadata
+- `0a 00 00 00` - .NET length prefix (10 characters)
+- String content in UTF-16LE
+- `89 33` after - this is `mov [rbx], esi` in x86-64!
+
+**The string is embedded near executable code, not in a clean data section.**
+
+---
+
+## GDB Stack Trace
+
+```
+#0  0x00007ffff7d3f5a4 in ?? () from /usr/lib/libc.so.6
+#1  raise () from /usr/lib/libc.so.6
+#2  abort () from /usr/lib/libc.so.6
+#3-#4  ?? () from /usr/lib/libc.so.6
+#5  free () from /usr/lib/libc.so.6
+#6  ?? () from libzstd.so    <-- CRASH POINT
+#7-#24  HytaleClient code (asset decompression)
+```
+
+Crash occurs in `libzstd.so` during `free()` after "Finished handling RequiredAssets".
+
+---
+
+## Hypotheses
+
+### 1. .NET AOT String Metadata (Most Likely)
+.NET AOT may have precomputed hashes, checksums, or relocation info for strings. Modifying string content breaks internal consistency, causing memory corruption when the runtime tries to use related data structures.
+
+### 2. Code/Data Interleaving
+The strings are embedded near x86 code (`89 33` = `mov [rbx], esi`). .NET AOT may use relative offsets that get invalidated when we modify nearby bytes.
+
+### 3. Binary Checksums
+The binary may have integrity checks for certain sections that we're invalidating by patching.
+
+### 4. Timing-Dependent Race Condition
+The fact that it works randomly (~30% of the time with jemalloc) suggests a race condition that's affected by:
+- Memory layout changes from patching
+- Allocator behavior differences
+- CPU scheduling
+
+---
+
+## Valgrind Results (Misleading)
+
+- Valgrind showed NO memory corruption errors
+- Game ran successfully under Valgrind (slower execution)
+- This suggested jemalloc would fix it, but it doesn't consistently work
+
+The slowdown from Valgrind likely masks the race condition timing.
+
+---
+
+## Current Launcher Implementation
+
+The launcher attempts:
+1. Auto-detect jemalloc at common paths
+2. Auto-install jemalloc via pkexec if not found
+3. Launch game with `LD_PRELOAD` via shell command
+
+But this doesn't provide stable results.
+
+---
+
+## Potential Alternative Approaches (Not Yet Tried)
+
+### 1. LD_PRELOAD Network Hooking
+Instead of patching the binary, hook `getaddrinfo()` / `connect()` to redirect network calls at runtime. No binary modification needed.
+
+### 2. Local Proxy + Certificate
+Run a local HTTPS proxy that intercepts hytale.com traffic and redirects to custom server. Requires installing a custom CA certificate.
+
+### 3. DNS + iptables Redirect
+Use local DNS to resolve hytale.com to localhost, then iptables to redirect to actual custom server. Requires root/sudo.
+
+### 4. Container with Older glibc
+Run the game in a container with glibc < 2.41 where the stricter validation doesn't exist.
+
+### 5. Different Patching Location
+Find strings in a pure data section rather than code-adjacent areas.
+
+---
+
+## Files Reference
+
+**Binary:** `HytaleClient` (ELF 64-bit, ~39.9 MB)
+
+**Branch:** `fix/steamdeck-jemalloc-crash`
+
+---
+
+## Install jemalloc (Partial Mitigation)
+
+jemalloc may help in some cases (~30% success rate):
+
+```bash
+# Steam Deck / Arch Linux
+sudo pacman -S jemalloc
+
+# Ubuntu / Debian
+sudo apt install libjemalloc2
+
+# Fedora / RHEL
+sudo dnf install jemalloc
+```
+
+The launcher automatically uses jemalloc if found. To disable:
+```bash
+HYTALE_NO_JEMALLOC=1 npm start
+```
+
+---
+
+## Conclusion
+
+**No stable solution found.** The binary patching approach may be fundamentally incompatible with glibc 2.41's stricter heap validation when modifying .NET AOT compiled binaries.
+
+Alternative approaches (network hooking, proxy, container) may be required for reliable Steam Deck / Ubuntu LTS support.

+# Steam Deck / Linux Crash Fix
+
+## SOLUTION: Use jemalloc ✓
+
+The crash is caused by glibc 2.41's stricter heap validation. Using jemalloc as the memory allocator fixes the issue.
+
+### Install jemalloc
+
+```bash
+# Steam Deck / Arch Linux
+sudo pacman -S jemalloc
+
+# Ubuntu / Debian
+sudo apt install libjemalloc2
+
+# Fedora / RHEL
+sudo dnf install jemalloc
+```
+
+### Launcher Auto-Detection
+
+The launcher automatically uses jemalloc when installed. No manual configuration needed.
+
+To disable (for testing):
+```bash
+HYTALE_NO_JEMALLOC=1 npm start
+```
+
+### Manual Launch with jemalloc
+
+```bash
+cd ~/.hytalef2p/release/package/game/latest
+
+LD_PRELOAD=/usr/lib/libjemalloc.so.2 ./Client/HytaleClient --app-dir /home/deck/.hytalef2p/release/package/game/latest --java-exec /home/deck/.hytalef2p/release/package/jre/latest/bin/java --auth-mode authenticated --uuid YOUR_UUID --name Player --identity-token YOUR_TOKEN --session-token YOUR_TOKEN --user-dir /home/deck/.hytalesaves
+```
+
+---
+
+## Debug Commands (for troubleshooting)
+
+### Base Command
+```bash
+cd ~/.hytalef2p/release/package/game/latest
+```
+
+### GDB Stack Trace (for crash analysis)
+```bash
+gdb -ex "run --app-dir ..." ./Client/HytaleClient
+
+# After crash:
+bt
+bt full
+info registers
+quit
+```
+
+### Test glibc tunables (alternative fixes that didn't work reliably)
+
+**Disable tcache:**
+```bash
+GLIBC_TUNABLES=glibc.malloc.tcache_count=0 ./Client/HytaleClient ...
+```
+
+**Disable heap validation:**
+```bash
+MALLOC_CHECK_=0 ./Client/HytaleClient ...
+```
+
+### Binary Validation
+```bash
+file ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+ldd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+```
+
+### Hex Dump Commands
+```bash
+# Search for hytale.com UTF-16LE
+xxd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.original | grep "6800 7900 7400 6100 6c00 6500 2e00 6300 6f00 6d00"
+```
+
+---
+
+## Test Different Patch Modes
+
+```bash
+# Restore original
+cp ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.original ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
+rm ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.patched_custom
+
+# Test UTF-16LE mode
+HYTALE_PATCH_MODE=utf16le HYTALE_AUTH_DOMAIN=sanasol.ws npm start
+
+# Test length-prefixed mode (default)
+HYTALE_AUTH_DOMAIN=sanasol.ws npm start
+```

Auto-detects jemalloc if installed 2. Offers to auto-install if missing (password prompt) 3. Falls back to MALLOC_CHECK_=0 if jemalloc unavailable Install manually: sudo pacman -S jemalloc (Arch/Steam Deck) sudo apt install libjemalloc2 (Debian/Ubuntu) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-27 05:01:06 +01:00

Fazri Gading	e426690632	ci: add fixed-version PKGBUILD for Arch Linux releases this PKGBUILD intended for CI and GitHub release artifacts. targets tagged releases only and uses a fixed pkgver that matches the corresponding git tag. all of the VCS logic has been removed to PKGBUILD-git to ensure reproducible builds and stable versioning suitable for binary distribution. the build process relies on electron-builder directory output (--dir) and packages only the unpacked application into a standard Arch Linux package (.pkg.tar.zst). other distro format are excluded from this path and handled separately. this change establishes a clear separation between: - rolling AUR development builds (-git) - CI-generated, versioned Arch Linux release packages the result is predictable artifact naming, correct version alignment, and Arch-compliant packaging for downstream users.	2026-01-26 18:33:07 +08:00
Fazri Gading	78f76afe0a	aur: add proper VCS (-git) PKGBUILD created clean VCS-based PKGBUILD following arch packaging conventions. this explicitly marked as a rolling (-git) build and derives its version dynamically from git tags and commit history via pkgver(). previous hybrid approach has been changed. key changes: - use -git suffix to clearly indicate rolling source builds - set pkgver=0 and compute the actual version via pkgver() - build only a directory layout using electron-builder (--dir) - avoid generating AppImage, deb, rpm, or pacman installers - align build and package steps with Arch packaging guidelines note: this PKGBUILD is intended for development and AUR use only and is not suitable for binary redistribution or release artifacts.	2026-01-26 18:20:37 +08:00
