Remove mallopt and M_MMAP_THRESHOLD related code to support MUSL libc (Alpine Linux). The mallopt API is glibc-specific and causes compilation failures on MUSL-based systems. Changes: - Remove mallopt source files (linux.cc, darwin.cc, mallopt_win.cc) - Remove export_mallopt.cc and export_mallopt.h - Remove initMallopt binding from xprofiler.cc - Remove malloptInited and initMallopt from xprofiler.js - Remove enable_avoid_rss_leak and m_mmap_threshold config options - Remove mallopt.test.js test file This is a low-impact change since: - Only Linux (glibc) had functional implementation - macOS and Windows had empty stub implementations - The feature was for RSS leak prevention optimization only 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
fix: remove mallopt/M_MMAP_THRESHOLD for MUSL libc compatibility
This adds a new CI job that tests compilation and execution on Alpine Linux containers, which use MUSL libc instead of glibc. This ensures the mallopt removal changes work correctly on Alpine-based systems. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- Rename package to @youmindinc/xprofiler - Bump version to 3.2.0 for MUSL libc compatibility - Remove binary download config, always build from source - Update repository URLs to YouMindInc fork 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
The binary config is still needed for node-pre-gyp to locate the compiled .node file. Using --build-from-source flag ensures we always compile locally instead of downloading prebuilt binaries. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
__off64_t is glibc-specific and not available in MUSL libc (Alpine Linux). This adds a typedef to define __off64_t as off_t when not using glibc. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
