From 135cad46a3b899d9711fef571a1e3b6677a919a3 Mon Sep 17 00:00:00 2001 From: Steven Cowles Date: Wed, 20 Aug 2025 12:06:29 +0200 Subject: [PATCH] Fix JIT compilation issues in v0.2.2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Bundle LLVM libraries with full variant distributions - Fix hardcoded library paths using install_name_tool - Add variant-specific JIT configuration (lite: off, full: on) - Add comprehensive JIT functionality test suite - Prevent configuration issues when switching between variants ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Makefile | 41 +++++- package.json | 2 +- tests/run-all.js | 20 +++ tests/test-jit-issue.js | 291 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 350 insertions(+), 4 deletions(-) create mode 100755 tests/test-jit-issue.js diff --git a/Makefile b/Makefile index 5899824..5358fdf 100644 --- a/Makefile +++ b/Makefile @@ -66,11 +66,11 @@ else ifeq ($(VARIANT),full) endif endif -.PHONY: all build clean download extract configure compile install package test +.PHONY: all build clean download extract configure compile install bundle-deps package test all: build -build: download extract configure compile install package +build: download extract configure compile install bundle-deps package test: build @echo "๐Ÿงช Testing built binaries..." @@ -111,8 +111,43 @@ install: cd $(PGVECTOR_SRC) && make PG_CONFIG=$(PREFIX)/bin/pg_config @echo "๐Ÿ“ฆ Installing pgvector..." cd $(PGVECTOR_SRC) && make install PG_CONFIG=$(PREFIX)/bin/pg_config + @echo "โš™๏ธ Configuring variant-specific settings..." +ifeq ($(VARIANT),lite) + @echo " ๐Ÿ“ Configuring lite variant (JIT disabled)..." + @echo "# Lite variant configuration - JIT disabled" >> $(PREFIX)/share/postgresql.conf.sample + @echo "jit = off # JIT compilation not available in lite variant" >> $(PREFIX)/share/postgresql.conf.sample + @echo " โœ… Added JIT configuration to postgresql.conf.sample" +else ifeq ($(VARIANT),full) + @echo " ๐Ÿ“ Configuring full variant (JIT enabled)..." + @echo "# Full variant configuration - JIT enabled" >> $(PREFIX)/share/postgresql.conf.sample + @echo "jit = on # JIT compilation available with LLVM support" >> $(PREFIX)/share/postgresql.conf.sample + @echo " โœ… Added JIT configuration to postgresql.conf.sample" +endif + +bundle-deps: + @echo "๐Ÿ“ฆ Bundling runtime dependencies..." +ifeq ($(VARIANT),full) + ifeq ($(PLATFORM),darwin) + @echo " ๐Ÿ”— Bundling LLVM libraries for JIT support..." + @if [ -f "$(LLVM_PREFIX)/lib/libLLVM.dylib" ];
