pfg	05d0475c6c	Update to zig 0.15.2 (#24204) ... Fixes ENG-21287 Build times, from `bun run build && echo '//' >> src/main.zig && time bun run build` |Platform|0.14.1|0.15.2|Speedup| |-|-|-|-| |macos debug asan|126.90s|106.27s|1.19x| |macos debug noasan|60.62s|50.85s|1.19x| |linux debug asan|292.77s|241.45s|1.21x| |linux debug noasan|146.58s|130.94s|1.12x| |linux debug use_llvm=false|n/a|78.27s|1.87x| |windows debug asan|177.13s|142.55s|1.24x| Runtime performance: - next build memory usage may have gone up by 5%. Otherwise seems the same. Some code with writers may have gotten slower, especially one instance of a counting writer and a few instances of unbuffered writers that now have vtable overhead. - File size reduced by 800kb (from 100.2mb to 99.4mb) Improvements: - `@export` hack is no longer needed for watch - native x86_64 backend for linux builds faster. to use it, set use_llvm false and no_link_obj false. also set `ASAN_OPTIONS=detect_leaks=0` otherwise it will spam the output with tens of thousands of lines of debug info errors. may need to use the zig lldb fork for debugging. - zig test-obj, which we will be able to use for zig unit tests Still an issue: - false 'dependency loop' errors remain in watch mode - watch mode crashes observed Follow-up: - [ ] search `comptime Writer: type` and `comptime W: type` and remove - [ ] remove format_mode in our zig fork - [ ] remove deprecated.zig autoFormatLabelFallback - [ ] remove deprecated.zig autoFormatLabel - [ ] remove deprecated.BufferedWriter and BufferedReader - [ ] remove override_no_export_cpp_apis as it is no longer needed - [ ] css Parser(W) -> Parser, and remove all the comptime writer: type params - [ ] remove deprecated writer fully Files that add lines: ``` 649 src/deprecated.zig 167 scripts/pack-codegen-for-zig-team.ts 54 scripts/cleartrace-impl.js 46 scripts/cleartrace.ts 43 src/windows.zig 18 src/fs.zig 17 src/bun.js/ConsoleObject.zig 16 src/output.zig 12 src/bun.js/test/debug.zig 12 src/bun.js/node/node_fs.zig 8 src/env_loader.zig 7 src/css/printer.zig 7 src/cli/init_command.zig 7 src/bun.js/node.zig 6 src/string/escapeRegExp.zig 6 src/install/PnpmMatcher.zig 5 src/bun.js/webcore/Blob.zig 4 src/crash_handler.zig 4 src/bun.zig 3 src/install/lockfile/bun.lock.zig 3 src/cli/update_interactive_command.zig 3 src/cli/pack_command.zig 3 build.zig 2 src/Progress.zig 2 src/install/lockfile/lockfile_json_stringify_for_debugging.zig 2 src/css/small_list.zig 2 src/bun.js/webcore/prompt.zig 1 test/internal/ban-words.test.ts 1 test/internal/ban-limits.json 1 src/watcher/WatcherTrace.zig 1 src/transpiler.zig 1 src/shell/builtin/cp.zig 1 src/js_printer.zig 1 src/io/PipeReader.zig 1 src/install/bin.zig 1 src/css/selectors/selector.zig 1 src/cli/run_command.zig 1 src/bun.js/RuntimeTranspilerStore.zig 1 src/bun.js/bindings/JSRef.zig 1 src/bake/DevServer.zig ``` Files that remove lines: ``` -1 src/test/recover.zig -1 src/sql/postgres/SocketMonitor.zig -1 src/sql/mysql/MySQLRequestQueue.zig -1 src/sourcemap/CodeCoverage.zig -1 src/css/values/color_js.zig -1 src/compile_target.zig -1 src/bundler/linker_context/convertStmtsForChunk.zig -1 src/bundler/bundle_v2.zig -1 src/bun.js/webcore/blob/read_file.zig -1 src/ast/base.zig -2 src/sql/postgres/protocol/ArrayList.zig -2 src/shell/builtin/mkdir.zig -2 src/install/PackageManager/patchPackage.zig -2 src/install/PackageManager/PackageManagerDirectories.zig -2 src/fmt.zig -2 src/css/declaration.zig -2 src/css/css_parser.zig -2 src/collections/baby_list.zig -2 src/bun.js/bindings/ZigStackFrame.zig -2 src/ast/E.zig -3 src/StandaloneModuleGraph.zig -3 src/deps/picohttp.zig -3 src/deps/libuv.zig -3 src/btjs.zig -4 src/threading/Futex.zig -4 src/shell/builtin/touch.zig -4 src/meta.zig -4 src/install/lockfile.zig -4 src/css/selectors/parser.zig -5 src/shell/interpreter.zig -5 src/css/error.zig -5 src/bun.js/web_worker.zig -5 src/bun.js.zig -6 src/cli/test_command.zig -6 src/bun.js/VirtualMachine.zig -6 src/bun.js/uuid.zig -6 src/bun.js/bindings/JSValue.zig -9 src/bun.js/test/pretty_format.zig -9 src/bun.js/api/BunObject.zig -14 src/install/install_binding.zig -14 src/fd.zig -14 src/bun.js/node/path.zig -14 scripts/pack-codegen-for-zig-team.sh -17 src/bun.js/test/diff_format.zig ``` `git diff --numstat origin/main...HEAD | awk '{ print ($1-$2)"\t"$3 }' | sort -rn` --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Dylan Conway <dylan.conway567@gmail.com> Co-authored-by: Meghan Denny <meghan@bun.com> Co-authored-by: tayor.fish <contact@taylor.fish>	2025-11-10 14:38:26 -08:00
