When `addFromLibrary` was called on an already-emitted dependency, it\n   returned `undefined`. Using `.filter((x) \u003d\u003e x !\u003d \u0027\u0027)` did not filter\n   out `undefined`, causing `.join(\u0027\\n\u0027)` to emit an empty line for each\n   already-emitted dependency.\n2. Because `deps` is always an array (`??\u003d []`), the `deps ? ... : \u0027\u0027`\n   ternary always took the truthy branch and appended `\u0027\\n\u0027`, even when\n   no dependencies were emitted. This gave every `addFromLibrary` return\n   value a leading `\u0027\\n\u0027`.\n\nUse a `joinChunks` helper (`chunks.filter(Boolean).join(\u0027\\n\u0027)`) to join\nnon-empty dependency, doc comment, and content strings without extra\nnewlines.\n\nAlso update `indentify` in `src/parseTools.mjs` to indent the first line\nof non-empty strings, which previously only happened because of the\naccidental leading `\u0027\\n\u0027` on each item."

      "message": "Map code without a DWARF line to no location in wasm source maps (#28033)\n\n`wasm-sourcemap.py` drops DWARF rows with line 0, which LLVM uses for\ncode that does not come from a single source line, for example when it\nmerges several calls to `abort()` into one. The previous mapping then\ncovers that code too, so it is reported at an unrelated line.\n\nThis writes an entry with only the wasm offset at these rows instead. An\nentry without a source location ends the previous mapping, so the code\ngets no location. Binaryen does the same when it writes source maps\n(WebAssembly/binaryen#5906): one such entry for each run of code without\na location, and none before the first mapping. Binaryen and emsymbolizer\nalready read these entries. When this tool was written, Binaryen could\nnot, which is likely why the rows were dropped.\n\nEach entry adds about two bytes. The new test checks that code at line 0\nmaps to no location and that consecutive line 0 rows share one entry."

Linux and the old FS both\nfail the open when the truncation fails (see `FS.truncate` inside\n`FS.open`), and both skip the truncation for devices and FIFOs.\n\nChanges:\n- `doOpen` returns the error from `setSize`, closing the backend file\nfirst.\n- Truncation is skipped for non-regular files.\n- Fixed a small leak where the `EISDIR` and `EACCES` checks for\n`O_TRUNC` returned without closing the backend file. Now the checks are\ndone before the file is opened.\n- Node backend: when a file was only open read-only, `setSize` called\n`ftruncate` on the read-only host fd, which failed with `EINVAL`. This\ncaused two issues:\n- `open(O_RDONLY | O_TRUNC)` succeeded but left the file unchanged (the\nerror was ignored).\n- `truncate(path)` failed with `EINVAL` if the file was already open\nread-only.\n \n  `setSize` now truncates by path when the host fd is read-only.\n\nTests:\n- `wasmfs_opfs.c`: opening a blob-backed file with `O_RDONLY | O_TRUNC`\nnow fails with `EIO`.\n- `wasmfs_open.c`: opening `/dev/null` with `O_TRUNC` succeeds.\n- `truncate.c`: `truncate(path)` on a file that is open read-only\nsucceeds. I also changed `assert(f)` to `assert(f \u003e\u003d 0)` for the\n`open()` fds, since `-1` would pass `assert(f)`.\n\n`ftruncate()` on an `O_RDONLY` fd still succeeds on WasmFS (Linux\nreturns `EINVAL`).

NFC (#28004)\n\nThe first two `FUNC` calls in `TEST()` lacked a `return` statement,\ncausing the JS snippet to return `undefined`. When invoked via\n`EM_ASM_DOUBLE`, JS `ToNumber(undefined)` produces `NaN`, and formatting\nit with `%f` in musl depends on the `NaN` sign bit (`nan` vs `-nan`).\n\nStarting in V8 14.8 (`v8_enable_undefined_double`), V8 represents\n`undefined` in double arrays using a `NaN` bit pattern with the sign bit\nset (`0xfff6fffffff6ffff`), which causes `printf(\"%f\", ...)` to output\n`-nan` instead of `nan`.\n\nReturn `0` explicitly in those two `FUNC` calls so the test does not\ndepend on the engine\u0027s `NaN` bit pattern for `undefined`.\n\nFixes: #27984"

An\nexception is `--safe-firefox-profile`, which passes `-no-remote` and a\nfresh `--profile` to Firefox so that `browser_process` runs as a\nseparate, long-lived browser instance.\n\nIn the handoff case, `detect_browser_processes()` expects\n`current_browser_processes` to end up empty so that\n`is_browser_process_alive()` falls back to waiting for the page to call\n`exit()`. However, if the existing browser navigates to the page before\nthe handoff stub has finished exiting, `detect_browser_processes()`\nwould record `browser_process.pid` in `current_browser_processes`.\nMoments later, when the stub finishes exiting,\n`is_browser_process_alive()` would see that `browser_process.pid` no\nlonger exists (via `psutil`) and immediately shut down the web server.\n\nExclude `browser_process.pid` from `current_browser_processes` in this\ncase so its exit is not mistaken for the user closing the browser. Even\nif `browser_process` is not a short-lived stub and remains running,\n`is_browser_process_alive()` and `kill_browser_process()` already check\n`browser_process.poll()` directly.\n\nFixes: #27504"
